the year 2020 in Bitcoin Cash so far: a detailed history

the year 2020 in Bitcoin Cash so far: a detailed history
What follows at the bottom is a four page long chronological overview of what happened in BCH in 2020 so far. To make it more digestable and fun to read I start with my narrating of the story.
My attempt was to remain as objective as possible and "let the facts speak for themselve" with everything sourced. I also link to many read.cash articles, the decision of which are the important ones to include is certainly not easy, I count on the rest of the community if I overlooked anything important.

summary & my narrating of the story:
The year started out relatively calm, with cashfusion in "the news" and an older ongoing controversy between Amaury and Roger Ver being worked out. Starting Jan 22nd all debate broke loose with the announcement of “Infrastructure Funding Plan for Bitcoin Cash” by Jiang Zhuoer of BTC.TOP. To illustrate this point 2 days later coinspice ran the title " Roger Ver Praises Vigorous Debate, [...]" and 6 days, less than a week, later Chris Pacia made a read.cash post titled "The 253rd "Thoughts on developer funding" Article" which might have been only a slight exaggeration or he might have been counting. Part of the reason of the tsunami was the lack of worked out details. By the time of Pacia's post a lot had changed: Both BU, Bitcoin Verde and a group of miners had made announcements not to go along with "the plan".
On feb 1st, the second version of the IFP was announced by Jiang Zhuoer in a post “BCH miner donation plan update”. Two weeks later on Feb 15th, the third iteration was announced by Bitcoin ABC which was to be activated by hashrate voting and on the same day Flipstarter was introduced, a sign of the search for alternative solutions. After a few more days and a few more people coming out more against the IFP (including Jonald Fyookball, Mark Lundeberg & Josh Ellithorpe), BCHN was announced on feb 20th with a formal release a week later. Also feb 27th, the DAA was brought back into the conversation by Jonathan Toomim with his " The BCH difficulty adjustment algorithm is broken. Here's how to fix it." video. By early march the IFP was effectively dead with its author Jiang Zhuoer vowing to vote against it. This became clear to everyone when ABC, a day later sudddenly shifted gears towards non-protocol, donation based funding: the IFP was dead. End march ABCs 2020 Business Plan was announced as a way to raise $3.3 million. Mid april to mid may was the high time for voluntary funding with four node implementations and General Protocols, a BCH DeFi Startup successfully raising funds.
By May 15th, the 6th HF network upgrade things had pretty much cooled down. The upgraded included nothing controversial and even saw an unexpected doubling in the unconfirmed transaction chain. June 15th a month later things started to heat up again with the BCHN announcement to remove the "poison pill" or "automatic replay protection". 8th Jul Jonathan Toomim posted "BCH protocol upgrade proposal: Use ASERT as the new DAA" which promised the solution to the long dragging DAA problem. Jul 23th however an unexpected twist occurred when Amaury Séchet posted "Announcing the Grasberg DAA" an incompatible, alternative solution. This, again, sparked a ton of debate and discussion. Grasberg lasted just two weeks from Jul 23th to Aug 6th when ABC announced its plans for the november 2020 upgrade but it had successfully united the opposition in the meanwhile. ABCs plan for november included dropping grasberg in favour of aserti3–2d and introducing IFPv4. Now we're here August 8th, the IFP which was declared dead after just over a month (Jan 22-Mar 5) is now back in full force. The rest of the history is still being written but if p2p electronic cash is to succeed in any big regard it's very thinkable that these events will get into history books.

Warning: Blockchain difficulty adjustment affecting price movements

Below are notable difficulty adjustments when hash rate fell and block times become slower for Bitcoin.
  1. 26 Mar 2020 [difficulty adjustment -15.95%, avg block time 11min 54secs]. On the 28th price crashed from $6674 to $6138 ( -8%).
  2. 8 Nov 2019 [difficulty adjustment -7.1%, avg block time 10min 46secs]. On the same day price crashed from $9234 to $8783 ( -4.88%).
  3. The next big adjustment was around Nov to Dec 2018 and there were 3 big adjustments with high block times.

Current situation:
We are 1 day 10 hours from the next difficulty adjustment. Projected difficulty adjustment is -5.61% (https://fork.lol/pow/retarget), which could indicate a small dip. However, take note that the date of last adjustment was the 5th and the 3rd halving was on the 11th, between the 5th to the 11th there was increased hashrate from miners trying to mine the final week of 12.5btc that offset the really slow block times after the halving. Therefore it will be the next difficulty adjustment after the one on the 20th that will completely reflect the slower block times after the halving. Currently the median block time taken on the 17th was around 14min (-28.5% difficulty adjustment).
For people who do not understand blockchain, basically with the Bitcoin 3rd halving, mining profitability fell for a lot of miners and they probably turned off their miners therefore the blockchain mining time became considerably slower which is reflected with slow transaction speed and higher fees as seen currently. Bitcoin sellers moving their BTC from wallet to an exchange are faced with slow transaction speed and therefore the sell pressure of BTC fell considerably which will attribute to the current price increase. There is a correlation between sell pressure and blockchain congestion (the size of the correlation is undetermined).
There is going to be a race. A race between BTC price hiking high enough to attract more miners to reduce avg block times versus the closing window of roughly 2 weeks before the next difficulty adjustment. If the price does not jump high enough, the next difficulty adjustment in the first week of June could signal a huge dip.
I am not an expert. I just did some research on the above and wanted to share with fellow Bitcoin compatriots so that we can tread with caution and not lose our shirts. I do not plan to short BTC but I will exit my BTC positions if I expect double digit negative difficulty adjustment in early June.
Please visit the original post here https://www.reddit.com/Bitcoin/comments/gm23pe/warning_blockchain_difficulty_adjustment/
There are pictures in the original post as well as 2nd halving evidence with pics. I could not post pics here. If possible please upvote the original post, a lot of people downvote it. Not sure why people downvote it, maybe veterans attempting to hide information from newcomers to fleece them of their shirt.

Update 1:>! As of writing, I have opened a small short position on Bitcoin. Stop loss around 10k, estimated take profit around 8500. The reason is because the difficulty adjustment in the next 20 hours, even though is just -5% roughly is still significant. I direct you to look into all the difficulty adjustments in the last 2 years and you will know how rare it is. The ones I caught were all listed at the very top of the post. Since it is my first time shorting BTC, I take this as a learning opportunity so that I will have some experience to face the bigger difficulty adjustment in the first week of June. Analysis into execution, even in failure I am happy.!<
Update 2: The difficulty adjustment (DA) happened roughly 6 hours ago and the sell pressure from -6% DA did not seem to be affecting the market much. However, please take a look now at the estimation for the next DA.
On https://bitcoin.clarkmoody.com/dashboard/ it is estimated to be -25%.
On https://fork.lol/pow/retarget estimated to be -18%.
On https://www.blockchain.com/charts/median-confirmation-time the median block time for the last day was 16.8min.
My original proposition that the true DA of the halving can only be realized in the next DA stands and that it will be considerable. The increased sell pressure from that DA will be highly significant. That is why there is a race by current miners to get the BTC price up high enough to attract more miners to not have the DA drop too much.
Update 3: Current BTC price at $9100 ( ~39 hours after DA). Then again BTC could have dropped from all sorts of reason. However the coincidence with the DA and with all the past DA is just too high to simply shrug off as irrelevant. Anyways past result cannot predict future ones, stay safe with the trading. Will no longer check on this post.

[Paracosm Discord] Hans's Inspiring Conv: Tangle Inside

2/6
Disclaimer:
This is my editing, so there could be some misunderstandings.
Anyone who wants to read everything should go to the 'spec' of Paracosm discord.
IMHO, Hans's philosophy and motivation is worth sharing widely.



Hans Moog [IF]어제 오전 7:57
People are more motivated then ever

Hans Moog [IF]어제 오전 8:02
the point is that the IF is not going to be there forever - its not meant to
having a self sustainable ecosystem is very important for the maturity of the protocol

Hans Moog [IF]어제 오전 8:03
No it's not
if IF would cease to exist tomorrow - it would be finished by the people working for the IF anyway
I am 100% sure
and if i would have to do it alone ...

Hans Moog [IF]어제 오전 8:05
we can all do it together - and we are actually doing it already
hornet and goshimmer have VERY close ties
they are really good friends and very capable coders
its an honor to work with them

Hans Moog [IF]어제 오전 8:06
[when do you reckon the shift to binary will take place?]
its being merged in goshimmer tomorrow :smile:

Hans Moog [IF]어제 오전 8:14
[about Multiverse]
the last statements of popov was that it "might work"
he still has some concerns
i guess he still tends to think the chances of it not working as bigger than the chances of it working
I am 100% sure it works - but maybe its on me to prove that with a fully functional prototype.

Hans Moog [IF]어제 오전 8:17
My goal is to show a prototype being able to process 10 million tps by the mid of this year - we will see if I can pull this off
maybe time will be rare, considering the parallel work on coordicide
maybe I should aim for end of 2020 instead

Hans Moog [IF]어제 오전 8:19
of course it includes sharding
that whole point of IOTA is sharding
and a completely new form of sharding

Hans Moog [IF]어제 오전 8:19
[why 10m TPS?]
its just a random number
some kind of goal post
so you can process the entirety of bitcoins history in 1minute and 30 seconds?
would be a nice thing

Hans Moog [IF]어제 오전 8:21
coordicide and multiverse would essentially use the same sharding principles
I hope that we can share more on that soon
Oh its quite concrete
we are starting to write math papers about it already

Hans Moog [IF]어제 오전 8:23
FPC is perfectly fine for sharding
you have to forget the discrete sharding world of blockchains where you just make n copies of the same thing
its very different


Hans Moog [IF]어제 오전 8:30
I would LOVE to share that with you but maybe just wait a but longer - we will be more open about this pretty soon
let's just say that we still have some aces in our sleeves

Hans Moog [IF]어제 오전 8:49
nope
I am completely new in crypto but I am pretty sure that some people might "know me from before"
if they would know what I did before

Hans Moog [IF]어제 오전 8:57
dude the IF has reached a stage where it would survive without anbybody
I could drop dead tomorrow and the IF would continue, same goes for David or anybody else

Hans Moog [IF]어제 오전 9:00
all the corporates and everything ... it might not be fully reflected in the price yet but IOTA has a really really bright future

Hans Moog [IF]어제 오전 9:01
I think we are starting to see a pretty bullish sentiment around IOTA lately
I only hope that its due to our increased transparency with a clear roadmap and everyhting, and not just some random fluke in the prices
It would just feel much more "rewarding" to be a consequence of our efforts :joy:

Hans Moog [IF]어제 오전 9:05
i am buying more IOTA every month : was very happy about the low prices
but I can understand that if you just "have to believe" and have no insight about the actual progress, then these prices can feel more concerning than a "bargain"

Hans Moog [IF]어제 오전 9:13
Do you really expect a guy working on IOTA to not be bullish about the tech and everything?
I am not in IOTA for the moneyzzz

Hans Moog [IF]어제 오전 9:18
if you are asking for investment advice, then I am most probably the worst person to ask
as my trades in crypto have always been horrible

Hans Moog [IF]어제 오전 9:20
I didn't have the chance to be around in the ICO days so I need to take what's left

Hans Moog [IF]어제 오전 9:27
I don't know man - everybody that I know is not willing to sell

Hans Moog [IF]어제 오전 9:35
Yassin is the proof that "reputation" is worth something
A man of honor - my deepest respect to you man
People who stick to their word and can be trusted are sadly a rare thing in today's world

Hans Moog [IF]어제 오전 9:39
I anyway think that we have way too much tribalism in crypto
people should really stop praising "people and projects" and instead start to praise ideas and concepts

Hans Moog [IF]어제 오전 9:43
I mean I get the whole concept of having a single currency and shit, but if the tech is bad? I mean this is the first time in the history of humans that we can "design" the very foundation of our social and economical layer
why would we not go for the best available tech?
bitcoin was "a breakthrough" when it was released
and it helped to kickstart a whole field of research
but its clearly not the best possible solution

Hans Moog [IF]어제 오전 9:47
ultimately the best tech will win
just look at bitcoins dominance
its fading long term
sure it was time for a correction from the 2017 run of alts

Hans Moog [IF]어제 오전 9:47
but the overall trend is pretty clear
bitcoins days are numbered

Hans Moog [IF]어제 오전 9:54
maybe I can leak one thing about IOTA's sharding solution without giving away too much: Every single node can individually decide how much data it wants to process - so you can have very very resource-constrained nodes like sensors and stuff in the same network as nodes with hundreds of cores and they will be able to work together seamlessly
there will essentially be no "minimum hardware requirements" for a node (of course you have "some" requirements to even be able to run some kind of logic)

Hans Moog [IF]어제 오전 9:56
We are on the forefront of research when it comes to VDF's but its not really related
VDFs would maybe be a way to replace PoW in the future as a rate control mechanism

Hans Moog [IF]어제 오전 9:58
you don't need big nodes
you can be as big as you want to be
but naturally some nodes will have more power than others

Hans Moog [IF]어제 오전 10:01
possible - the whole mana system is based on "reputation", if you run a reliable cluster of nodes that people are willing to use, then you can earn mana
and since mana decides how many transactions you can issue, you can of course "allow others to use your resources" for money
so operating a reliable node cluster could be sth that people might do "for a living" in the future
maybe it would be best to build up a reputation already today

Hans Moog [IF]어제 오전 10:03
if you have funds in the network, then you will generate more than enough mana to have enough "shares" in the network to use it
for free
but if anybody wants to just piggyback on the network without holding tokens, then he might have to pay a "fee"

Hans Moog [IF]어제 오전 10:05
if you want to send a lot of data transactions, then you better have some tokens
I mean its just fair, right?
you don't have any stake in the network but you wanna use it? then pay for it
but people who have funds in the network can use it for free

Hans Moog [IF]어제 오전 10:07
i think ultimately the community will provide a plugin for the nodes, where you can "automatically" rent your excess reputation for some income

Hans Moog [IF]어제 오전 10:08
[what would the income be ?]
tokens
IOTA

Hans Moog [IF]어제 오전 10:09
by the people who want to use the network more than what their token holding would allow them to
so they rent "mana" from the people who have it

Hans Moog [IF]어제 오전 10:10
the internet took off when flat-rate emerged
and prices became predictable
the same is true for crypto

Hans Moog [IF]어제 오전 10:11
thats why companies like IOTA so much ... it creates a platform that has "predictable" prices
any mining based crypto will never be able to offer the same
Beeing feeless is not just a "funny feature", its the key to mass adoption

Hans Moog [IF]어제 오전 10:14
If I run a node and have funds in the network, then why would I pay anybody anything? I am supporting the network already by using it

Hans Moog [IF]어제 오전 10:16
Yeah we are using "mana 2" now which is also the one that is implemented in the goshimmer mana package
the formulas are going to change a bit tho
we had like 16 different versions of mana with all very different implications on game theory and code

Hans Moog [IF]어제 오전 10:18
but serguei is the expert when it comes to game theory and we are pretty confident that we have chosen the correct survivor

Hans Moog [IF]어제 오전 10:19
[The mana implementation does seem like the slipperiest slope]
it uses a few economic theories from the early 20th century (from silvio gesell) by having smth like a "demurrage function"
so the rich dont get richer
its software - if any design decision turns out to be problematic, you patch it

Hans Moog [IF]어제 오전 10:20
[So it’s hard to maintain a high mana]
its not like you have to live with it for thousands of years like in our current FIAT system
if you make it right from the start, the rich will never become that powerful that they could even dare to fork

Hans Moog [IF]어제 오전 10:22
you are "RENTING" out your excess resources
that doesn't mean that you will broadcast everything unseen
If somebody tries to use your node to perform an attack you will just ignore it
of course you might "lose the fees" that they would be willing to pay you to perform this attack,
but ultimately you will have to decide what is more valuable to you
the few cents of IOTA you earn or your "reputation / mana"

Hans Moog [IF]어제 오전 10:25
the nodes will perform all of the sanity checks, so they don't "accidently" take part in an attack of course
the point is that its a voting system based on mana
if I use your node to "issue a transaction",
then I maybe pay you for issuing this tx
but your "opinion on that tx" is independent of that

Hans Moog [IF]어제 오전 10:29
actually I even think that the whole coordicide principles especially in connection with the sharding are very much in line with cfb's initial vision - and I am actually a bit sad that he never really dared to honestly look into them

Hans Moog [IF]어제 오전 10:29
I was even thinking about "naming" the multiverse "cfbs vision" once
maybe its more (pauls's vision) than cfbs vision
paul handy was one of the other early developers of IOTA btw.
and a very very smart person I have to say
a lot of the ideas that we are currently pursuing go back to his line of thinking

Hans Moog [IF]어제 오전 10:32
the infamous "ontology principles"
the ultimate goal is to be able to run "anything" on the tangle - not just value transfers but literally anything, event remotely related to DLT's
I envision IOTA being a general purpose DLT platform
pretty much like TCP/IP was for the internet

Hans Moog [IF]어제 오전 10:36
I introduced "broadcasts" a few days ago as a new concept that is the equivalent of UDP messages

Hans Moog [IF]어제 오전 10:49
I think that one of the things where cfb and me disagree regarding the "vision of IOTA" is that he think thats we should "finalize" the protocol as soon as possible (or "set it in stone" as he likes to call it), so hardware manufacturer can start to build hardware, whereas I think that it makes much more sense for it to be something like an "open evolving standard" that is so flexible that you can literally build whatever the fuck you want based on this protocol.

The internet wouldn't have been the internet, if it would have "just" been for sending scientific messages between researchers.
I can not anticipate and know what humans might do with DLT in the future, so limiting myself to "only value transfers" is IMHO the wrong decision.
for something to be successful, it needs to be able to "model" everything that could possibly exist

Hans Moog [IF]어제 오전 10:51
IOTA will be able to run "anything" on top of it - even "virtual instances of other cryptocurrencies"
and its not going to be some quirky slow emulation - it would most probably even be faster and more reliable than when being implemented without it

Hans Moog [IF]어제 오전 10:52
similar to "INTEL inside" you will most probably see sth like "Tangle inside" soon

Hans Moog [IF]어제 오전 10:54
"any application" running on top of the tangle (MAM, DID, Qubic, Matrix ... you name them) would ALWAYS have to be able to process IOTA value transfers
THAT's what will give the token a value

Hans Moog [IF]어제 오전 10:55
if everybody can already "speak the same language" anyway, then people will also use that language to communicate
which means that people will use the IOTA token to transfer value
so we don't need to "force ourselves" on others - they will come by themselves
because its the only thing that makes sense

Hans Moog [IF]어제 오전 10:57
[so Hans, $10 EOY still ?]
if btc stays where it is?
hard to achieve i'd say
most probably not
it always takes some time for people to "wake up"
dunno maybe it goes fast
most weak hands are gone in IOTA

Hans Moog [IF]어제 오전 11:00
But seriously guys ... the price of course is interesting but if we are able to pull this off, then this will be the start of a new form of society
it will affect everything
the way we interact .... even the way we behave towards each other
I am not even sure if you need to be "rich" in that kind of society
Star trek sounds like a nice vision


Hans Moog [IF]어제 오전 11:20
[once IOTA is completely implemented, its gonna be a matter of energy consumption optimization race I guess?]
ultimately, yes
whatever crypto is going to be the "cheapest" one to "operate" will win

Hans Moog [IF]어제 오전 11:22
BUT that is at the same time "expressive" enough to not have "niches" for weird competitors, that claim to be even a "little bit better" in one of the aspects
it needs to be the best possible solution that humans are most probably able to come up with

Hans Moog [IF]어제 오전 11:23
if even the smallest something can be improved, then it should become part of the core rather than a competing project
not having miners and being able to "upgrade" whenever it is necessary, is what will give IOTA power
not setting stuff in stone today

Hans Moog [IF]어제 오전 11:29
I guess what fascinates me the most about IOTA is that people have a different kind of philosophy - in crypto people are usually sharing the mindset of "let's destroy the banks ... or .... the FED ... or whoever they consider to be their enemy
IOTA for me is not so much about "destroying somebody else" rather than "creating something new"

Hans Moog [IF]어제 오전 11:30
But the "mindset and motivation" makes all the difference
And I feel like large parts of the community "understand and share" that vision

Hans Moog [IF]어제 오전 11:34
there are plenty of "problems" where DLT is not the right answer
but there are most probably also quite a few that we haven't even thought about, yet
that go way beyond just "finance"

Hans Moog [IF]어제 오전 11:38
[Has IF any plans for anonymous transactions Hans?]
it's current not our main point of research but I would say ultimately yes
the fact thats its feeless make "mixing" funds a very feasible solution
But even on top of that (like zero knowledge proofs and stuff) If there is a use case, then you should be able to do it with IOTA.
that's what I mean with "general purpose DLT" platform
whatever is possible should be doable with the protocol - not "just" IoT value transfers

Hans Moog [IF]어제 오전 11:42
everything you could most probably think of
the same way as TCP/IP allows you to play computer games, send emails, or watch streams

Hans Moog [IF]어제 오전 11:48
tomorrow I start merging the first ledger-related stuff into the development branch
from the outside it will most probably look like any other day : but starting to work on the "final version" which is supposed to be ready end of Q1 is a big milestone for us
2 months left

Hans Moog [IF]어제 오후 12:04
100% agree - let's finish this shit!
we have "talked" for quite a while - the coming months, we will have to show what we "have"

Warning: Blockchain difficulty adjustment affecting price movement

Warning: Blockchain difficulty adjustment affecting price movement
Below are notable difficulty adjustments when hash rate fell and block times become slower for Bitcoin.
  1. 26 Mar 2020 [difficulty adjustment -15.95%, avg block time 11min 54secs]. On the 28th price crashed from $6674 to $6138 ( -8%).
  2. 8 Nov 2019 [difficulty adjustment -7.1%, avg block time 10min 46secs]. On the same day price crashed from $9234 to $8783 ( -4.88%).
  3. The next big adjustment was around Nov to Dec 2018 and there were 3 big adjustments with high block times.
  • 19 Dec 2018 [-9.56%, avg block time 11min 3secs]
  • 3 Dec 2018 [-15.13%, avg block time 11min 47secs]
  • 17 Nov 2018 [-7.39%, avg block time 10min 48secs]
  • There was huge drop off starting on 14th Nov all the way to a bottom on 14-15th Dec ($6351 to $3288 around -48%).

Current situation:
We are 1 day 10 hours from the next difficulty adjustment. Projected difficulty adjustment is -5.61% (https://fork.lol/pow/retarget), which could indicate a small dip. However, take note that the date of last adjustment was the 5th and the 3rd halving was on the 11th, between the 5th to the 11th there was increased hashrate from miners trying to mine the final week of 12.5btc that offset the really slow block times after the halving. Therefore it will be the next difficulty adjustment after the one on the 20th that will completely reflect the slower block times after the halving. Currently the median block time taken on the 17th was around 14min (-28.5% difficulty adjustment).

https://preview.redd.it/ysnv85wh0lz41.jpg?width=597&format=pjpg&auto=webp&s=e130b077f9dc2fc9d02666ef89e6f9249a05f535
For people who do not understand blockchain, basically with the Bitcoin 3rd halving, mining profitability fell for a lot of miners and they probably turned off their miners therefore the blockchain mining time became considerably slower which is reflected with slow transaction speed and higher fees as seen currently. Bitcoin sellers moving their BTC from wallet to an exchange are faced with slow transaction speed and therefore the sell pressure of BTC fell considerably which will attribute to the current price increase. There is a correlation between sell pressure and blockchain congestion (the size of the correlation is undetermined).
There is going to be a race. A race between BTC price hiking high enough to attract more miners to reduce avg block times versus the closing window of roughly 2 weeks before the next difficulty adjustment. If the price does not jump high enough, the next difficulty adjustment in the first week of June could signal a huge dip.
I am not an expert. I just did some research on the above and wanted to share with fellow Bitcoin compatriots so that we can tread with caution and not lose our shirts. I do not plan to short BTC but I will exit my BTC positions if I expect double digit negative difficulty adjustment in early June.

Bitcoin 2nd halving evidence:

2nd halving falls between the 5th and the 19th adjustment so it is only reflected on the 3rd of Aug difficulty adjustment ( -5.43%).

See the dip on the 3rd of August. Price fell from $600 to $533 about 11% drop.
Update 1:>! As of writing, I have opened a small short position on Bitcoin. Stop loss around 10k, estimated take profit around 8500. The reason is because the difficulty adjustment in the next 20 hours, even though is just -5% roughly is still significant. I direct you to look into all the difficulty adjustments in the last 2 years and you will know how rare it is. The ones I caught were all listed at the very top of the post. Since it is my first time shorting BTC, I take this as a learning opportunity so that I will have some experience to face the bigger difficulty adjustment in the first week of June. Analysis into execution, even in failure I am happy.!<
Update 2: The difficulty adjustment (DA) happened roughly 6 hours ago and the sell pressure from -6% DA did not seem to be affecting the market much. However, please take a look now at the estimation for the next DA.
On https://bitcoin.clarkmoody.com/dashboard/ it is estimated to be -25%.
On https://fork.lol/pow/retarget estimated to be -18%.
On https://www.blockchain.com/charts/median-confirmation-time the median block time for the last day was 16.8min.
My original proposition that the true DA of the halving can only be realized in the next DA stands and that it will be considerable. The increased sell pressure from that DA will be highly significant. That is why there is a race by current miners to get the BTC price up high enough to attract more miners to not have the DA drop too much.

I just looked up to mine btc and its a total loss.

I was looking foe options for mining, from cloud mining to buying an antminer. After much calculation everything is at loss. Miners how do you do it?? From where i live i pay 0.2 dollars for 1kw,and even with 20ths from latest bitminer, my calculations were still at a loss. Is the whole community operating on loss? What needs to be done for a profit sustained network.? EDIT >>

The biggest cryptocurrency thefts in the last 10 years

In this article, we will try to remember all the major theft of cryptocurrencies over the past 10 years.
1. Bitstamp $5.3 mln (BTC), January 4th, 2015
On January 4, 2015, the operational hot wallet of Bitstamp announced that it was hacked by an anonymous hacker and 19,000 Bitcoins (worth of $5 million) were lost.
The initiation of the attack fell on November 4, 2014. Then Damian Merlak, the CTO of the exchange, was offered free tickets to punk rock festival Punk Rock Holiday 2015 via Skype, knowing that Merlak is interested in such music and he plays in the band. To receive the tickets, he was asked to fill out a participant questionnaire by sending a file named “Punk Rock Holiday 2015 TICKET Form1.doc”. This file contained the VBA script. By opening the file, he downloaded the malware on his computer. Although Merlak did not suspect wrong and has opened the "application form", to any critical consequences, this did not open access to the funds of exchange.
The attackers, however, did not give up. The attack continued for five weeks, during which hackers presented themselves as journalists, then headhunters.
Finally, the attackers were lucky. On December 11, 2014, the infected word document was opened on his machine by Bitstamp system administrator Luka Kodric, who had access to the exchange wallet. The file came to the victim by email, allegedly on behalf of an employee of the Association for computer science, although in fact, as the investigation showed, the traces of the file lead deep into Tor. Hackers were not limited to just one letter. Skype attacker pretending to be an employee of the Association for computing machinery, convinced that his Frame though to make international honor society, which required some paperwork. Kodric believed.
By installing a Trojan on Kodriс's computer hackers were able to obtain direct access to the hot wallet of the exchange. The logs show that the attacker, under the account of Kodric, gained access to the server LNXSRVBTC, where he kept the wallet file.dat, and the DORNATA server where the password was stored. Then the servers were redirected to a certain IP address that belongs to one of the providers of Germany.
There are still no official reports of arrests in this case. Obviously, the case is complicated by the fact that the hackers are outside the UK, and the investigation has to cooperate with law enforcement agencies in other countries.
2. GateHub $9.5 mln (XRP), June 1th, 2019
Hackers have compromised nearly 100 XRP Ledger wallets on cryptocurrency wallet service GateHub. The incident was reported by GateHub in a preliminary statement on June 6.
XRP enthusiast Thomas Silkjær, who first noticed the suspicious activity, estimates that the hackers have stolen nearly $10 million worth of cryptocurrency (23,200,000 XRP), $5.5 million (13,100,000 XRP) of which has already been laundered through exchanges and mixer services.
GateHub notes that it is still conducting an investigation and therefore cannot publish any official findings. Also, GateHub advises victims to make complaints to the relevant authorities of their jurisdiction.
3. Tether, $30.9 mln (USDT), November 19th, 2017
Tether created a digital currency called "US tokens" (USDT) — they could be used to trade real goods using Bitcoin, Litecoin and Ether. By depositing $1 in Tether, the user received 1 USD, which can be converted back into fiat. On November 19, 2017, the attacker gained access to the main Tether wallet and withdrew $ 30.9 million in tokens. For the transaction, he used a Bitcoin address, which means that it was irreversible.
To fix the situation, Tether took action by which the hacker was unable to withdraw the stolen money to fiat or Bitcoin, but the panic led to a decrease in the value of Bitcoin.
4. Ethereum, $31 mln (ETH), July 20th, 2017
On July 20, 2017, the hacker transferred 153,037 Ethers to $31 million from three very large wallets owned by SwarmCity, Edgeless Casino and Eternity. Unknown fraudster managed to change the ownership of wallets, taking advantage of the vulnerability with multiple signatures.
First, the theft was noticed by the developers of SwarmCity.
Further events deserve a place in history: "white hackers" returned the stolen funds, and then protected other compromised accounts. They acted in the same way as criminals, who stole funds from vulnerable wallets — just not for themselves. And it all happened in less than a day.
5. Dao (Decentralized Autonomous Organization) $70 mln (ETH), June 18th, 2016
On June 18, 2016, members of the Ethereum community noticed that funds were being drained from the DAO and the overall ETH balance of the smart contract was going down. A total of 3.6 million Ether (worth around $70 million at the time) was drained by the hacker in the first few hours. The attack was possible because of an exploit found in the splitting function. The attackes withdrew Ether from the DAO smart contract multiple times using the same DAO Tokens. This was possible due to what is known as a recursive call exploit.
In this exploit, the attacker was able to "ask" the smart contract (DAO) to give the Ether back multiple times before the smart contract could update its own balance. There were two main faults that made this possible: the fact that when the DAO smart contract was created the coders did not take into account the possibility of a recursive call, and the fact that the smart contract first sent the ETH funds and then updated the internal token balance.
It's important to understand that this bug did not come from Ethereum itself, but from this one application that was built on Ethereum. The code written for the DAO had multiple bugs, and the recursive call exploit was one of them. Another way to look at this situation is to compare Ethereum to the Internet and any application based on Ethereum to a website: if a website is not working, it doesn't mean that the Internet is not working, it simply means that one website has a problem.
The hacker stopped draining the DAO for unknown reasons, even though they could have continued to do so.
The Ethereum community and team quickly took control of the situation and presented multiple proposals to deal with the exploit. In order to prevent the hacker from cashing in the Ether from his child DAO after the standard 28 days, a soft-fork was voted on and came very close to being introduced. A few hours before it was set to be released, a few members of the community found a bug with the implementation that opened a denial-of-service attack vector. This soft fork was designed to blacklist all the transactions made from the DAO.
6. NiceHash, 4736.42 (BTC), December 6th, 2017
NiceHash is a Slovenian cryptocurrency hash power broker with integrated marketplace that connects sellers of hashing power (miners) with buyers of hashing power using the sharing economy approach.
On December 6, 2017, the company's servers became the target of attack. At first, Reddit users reported that they could not access their funds and make transactions — when they tried to log in, they were shown a message about a service interruption. In the end, it became known that the service had undergone a major cyberattack and 4736,42 Bitcoins disappeared without a trace.
Despite heavy losses, NiceHash was able to continue working, but CEO and founder Marco Koval resigned, giving way to a new team. The company managed to maintain the trust of investors and began to strengthen the protection of its systems.
7. Mt.Gox, 850000 (BTC), June 19th, 2011
The Hacking Of Mt.Gox was one of the biggest Bitcoin thefts in history. It was the work of highly professional hackers using complex vulnerabilities.
A hacker (or a group of hackers) allegedly gained access to a computer owned by one of the auditors and used a security vulnerability to access Mt.Gox servers, then changed the nominal value of Bitcoin to 1 cent per coin.
Then they brought out about 2000 BTC. Some customers, without knowing it, conducted transactions at this low price, a total of 650 BTC, and despite the fact that the hacking hit the headlines around the world, no Bitcoin could be returned.
To increase investor confidence, the company has compensated all of the stolen coins, placed most of the remaining funds in offline storage, and the next couple of years was considered the most reliable Bitcoin exchanger in the world.
However, it was only an illusion of reliability.
The problems of the organization were much more serious, and the management probably did not even know about them.
CEO of Mt.Gox, Mark Karpeles, was originally a developer, but over time he stopped delving into technical details, basking in the rays of glory — because he created the world's largest platform for cryptocurrency exchange. At that time Mt.Gox handled over 70% of all Bitcoin transactions.
And, of course, there were those who wanted to take advantage of the technological weakness of the service. At some point, hackers made it so that Bitcoins could be bought at any price, and within minutes millions of dollars worth of coins were sold — mostly for pennies. World prices for Bitcoin stabilized in a few minutes, but it was too late.
As a result, Mt.Gox lost about 850,000 Bitcoins. The exchange had to declare bankruptcy, hundreds of thousands of people lost money, and the Japanese authorities arrested CEO Mark Karpeles for fraud. He pleaded not guilty and was subsequently released. In 2014, the authorities restored some of the Bitcoins remaining at the old addresses, but did not transfer them to the exchange, and created a trust to compensate for the losses of creditors.
8. Coincheck, $530 mln, January 26th, 2018
The sum was astonishing, and even surpassed the infamous Mt.Gox hack.
While Mt.Gox shortly filed for bankruptcy following the hack, Coincheck has surprisingly remained in business and was even recently approved as a licensed exchange by Japan’s Financial Services (FSA).
Coincheck was founded in 2014 in Japan and was one of the most popular cryptocurrency exchanges in the country. Offering a wide variety of digital assets including Bitcoin, Ether, LISK, and NEM, Coincheck was an emerging exchange that joined the Japan Blockchain Association.
Since Coincheck was founded it 2014, it was incidentally not subject to new exchange registration requirements with Japan’s FSA — who rolled out a framework after Mt. Gox –, and eventually was a contributing factor to its poor security standards that led to the hack.
On January 26th, 2018, Coincheck posted on their blog detailing that they were restricting NEM deposits and withdrawals, along with most other methods for buying or selling cryptocurrencies on the platform. Speculation arose that the exchange had been hacked, and the NEM developers issued a statement saying they were unaware of any technical glitches in the NEM protocol and any issues were a result of the exchange’s security.
Coincheck subsequently held a high-profile conference where they confirmed that hackers had absconded with 500 million NEM tokens that were then distributed to 19 different addresses on the network. Totaling roughly $530 million at the time — NEM was hovering around $1 then — the Coincheck hack was considered the largest theft in the industry’s history.
Coincheck was compelled to reveal some embarrassing details about their exchange’s security, mentioning how they stored all of the NEM in a single hot wallet and did not use the NEM multisignature contract security recommended by the developers.
Simultaneously, the NEM developers team had tagged all of the NEM stolen in the hack with a message identifying the funds as stolen so that other exchanges would not accept them. However, NEM announced they were ending their hunt for the stolen NEM for unspecified reasons several months later, and speculation persisted that hackers were close to cashing out the stolen funds on the dark web.
Mainstream media covered the hack extensively and compared it to similar failures by cryptocurrency exchanges in the past to meet adequate security standards. At the time, most media coverage of cryptocurrencies was centered on their obscure nature, dramatic volatility, and lack of security. Coincheck’s hack fueled that narrative considerably as the stolen sum was eye-popping and the cryptocurrency used — NEM — was unknown to most in the mainstream.
NEM depreciated rapidly following the hack, and the price fell even more throughout 2018, in line with the extended bear market in the broader industry. Currently, NEM is trading at approximately $0.07, a precipitous fall from ATH over $1.60 in early January.
The extent of the Coincheck hack was rivaled by only a few other hacks, notably the Mt.Gox hack. While nominally Coincheck is the largest hack in the industry’s history, the effects of Mt.Gox were significantly more impactful since the stolen funds consisted only of Bitcoin and caused a sustained market correction as well as an ongoing controversy with the stolen funds and founder. Moreover, Mt.Gox squandered 6% of the overall Bitcoin circulation at the time in a market that was much less mature than it is today.
Despite the fallout, Coincheck is now fully operational and registered with Japan’s FSA.
As practice shows, people make mistakes and these mistakes can cost a lot. Especially, when we talk about mad cryptoworld. Be careful and keep your private keys in a safe place.

I just looked up to mine btc and its a total loss.

I was looking foe options for mining, from cloud mining to buying an antminer. After much calculation everything is at loss. Miners how do you do it?? From where i live i pay 0.2 dollars for 1kw,and even with 20ths from latest bitminer, my calculations were still at a loss. Is the whole community operating on loss? What needs to be done for a profit sustained network.? EDIT >>

[Megathread] On August 1, 2017 at 6:12pm UTC (block 478559), a new altcoin called Bcash (BCH) has been created using Bitcoin's transaction history. Bitcoin itself continues to function normally.

What is happening?

In what has been touted as the culmination of a multi-year scaling debate, on August 1, 2017 at 6:12pm UTC (block 478559) a new altcoin was created from Bitcoin. The new altcoin is known as "Bcash" (BCH) or "Bitcoin Cash" (BCC) depending on which wallet/exchange you ask. In order to avoid confusion with actual Bitcoin and other altcoins, we recommend readers refer to the new altcoin as "Bcash" (BCH).
As with all altcoins, Bcash is technically off-topic for the /Bitcoin subreddit. However, Bcash was created based on Bitcoin's transaction history, and therefore all Bitcoin owners should be able to retrieve an equal amount of Bcash with some effort. Your Bitcoins are just as safe as they were before the chain split, but you should take care not to compromise your private keys if you wish to retrieve Bcash. This is not urgent unless you wish to trade immediately. If you choose to retrieve your Bcash, please be aware that consolidating your UTXOs will impact your privacy on both chains.
In order to help readers navigate this confusing situation and minimize disruption of relevant content, /Bitcoin has dedicated this sticky thread where readers can ask questions or leave comments pertaining to Bcash. If you are wondering how to retrieve your new altcoin holdings, please read the discussion thoroughly as your questions may already have been answered. If you don't see a similar question, please be sure to mention your wallet method and preferred exchange so that other readers can help address your concerns. You are also invited to submit new threads to the /Bcash subreddit if you so choose.
If you would like to understand the motives behind this new altcoin, please read The Future of “Bitcoin Cash:” An Interview with Bitcoin ABC lead developer Amaury Séchet.
A Beginner’s Guide to Claiming Your “Bitcoin Cash” (and Selling It) is a must-read for anyone feeling particularly lost.

But I thought we avoided a chain split?

For those of you who thought we avoided a chain split with the activation of BIP91 a couple weeks ago, here's a very loose summary of what happened on the Segwit (BIP141, BIP148, BIP91) front:
  1. Bitcoin Core team deployed Segwit (BIP141) last year
  2. Miners refused to activate Segwit via BIP9
  3. Users deployed UASF (BIP148 by shaolinfry) to require Segwit (BIP141) signaling by August 1st
  4. Miners activated BIP91 (by James Hilliard) on July 20th in response to UASF (BIP148)
  5. BIP91 complied with UASF (BIP148) by enforcing Segwit (BIP141) signaling ahead of August 1st
  6. Segwit BIP141 is expected to lock in on Tuesday, August 8th
  7. Segwit BIP141 is expected to activate on Monday, August 21st
  8. BIP148 activated successfully without any chain split
  9. Another altcoin called "SegWit2x" (B2X) may be created later this year, similar to Bcash but with less safety precautions regarding replay protection
Despite all the progress we're making in scaling Bitcoin both on-chain and off-chain, the Bcash crew has decided to part ways with the Bitcoin project by creating a new altcoin. The key differences are that they are attempting to gut Segwit from their forked client, as well as increasing the deprecated max_block_size attribute to 8MB.

Various Announcements:

Electrum 1 - Electrum 2 - Trezor - Ledger - Coinbase - Breadwallet - Bitfinex - Airbitz - Blockchain.info - Exodus - Jaxx - Kraken - Bittrex - Greyscale - Yobit - Bitcoin Core - Bitstamp - [Mycelium]() - [GreenAddress]() - BitcoinTalk - (Reply in comments to add other services)

/Bitcoin wishes Bcash a happy farewell and the best of luck in their new venture!

Possible hash rate reversal

Something very interesting that has happened which I haven't seen anyone comment on yet is the possible hash rate trend reversal. I've been keeping an eye on the bitcoin hash rate the last few weeks. As the price dropped I thought that with enough miners going offline there would be a chance of chain death, but watching it for 4 weeks I found my fears unfounded! However, I found it fascinating that even in this bear market, with price dropping for the past year, the hash rate still increased significantly until Oct. You can view the historical hash rate here:
https://bitinfocharts.com/comparison/bitcoin-hashrate.html#log
Since October, hash rate has been going down, which I was able to find also happened in Aug - Nov 2011. The bottom of the hash rate could be argued to be 20th / 27th Nov or 13th Dec. Price bottomed out during that time 21st November (I wasn't around during that time, have only been in the space for a year and was reading a coindesk article talking about price historical price highs and lows).
I've been watching hash rate for the last few weeks at this site:
https://bitcoinwisdom.com/bitcoin/difficulty
Looking at the most recent hash rate, it seems we're possibly back on the way up, with a hash rate reversal. I think it's still too early to know for sure, but seems to be a strong indication of hash rate rebounding. Another 12-24 hours I think should confirm it.
I am not calling the bottom, as there is no confirmed pattern here, more a hunch and some interesting metrics that are lining up, plus no one knows the future. However I am putting this forward as an interesting metric to discuss, as well as a possible reason for the increase in longs we've seen in the last few hours. Not sure if this is a lead measure or a lag measure, but worth discussing.
I'd be interested to hear what other people's thoughts are!
edit: Spelling and Grammar
edit2: This got a bit off topic, above when saying chain death, I was referring to chain death spiral, so not using correct terminology which may have contributed to the below discussion. Would prefer to move conversation to the original observation of hashing increase though.

The biggest cryptocurrency thefts in the last 10 years

In this article, we will try to remember all the major theft of cryptocurrencies over the past 10 years.
1. Bitstamp $5.3 mln (BTC), January 4th, 2015
On January 4, 2015, the operational hot wallet of Bitstamp announced that it was hacked by an anonymous hacker and 19,000 Bitcoins (worth of $5 million) were lost.
The initiation of the attack fell on November 4, 2014. Then Damian Merlak, the CTO of the exchange, was offered free tickets to punk rock festival Punk Rock Holiday 2015 via Skype, knowing that Merlak is interested in such music and he plays in the band. To receive the tickets, he was asked to fill out a participant questionnaire by sending a file named “Punk Rock Holiday 2015 TICKET Form1.doc”. This file contained the VBA script. By opening the file, he downloaded the malware on his computer. Although Merlak did not suspect wrong and has opened the "application form", to any critical consequences, this did not open access to the funds of exchange.
The attackers, however, did not give up. The attack continued for five weeks, during which hackers presented themselves as journalists, then headhunters.
Finally, the attackers were lucky. On December 11, 2014, the infected word document was opened on his machine by Bitstamp system administrator Luka Kodric, who had access to the exchange wallet. The file came to the victim by email, allegedly on behalf of an employee of the Association for computer science, although in fact, as the investigation showed, the traces of the file lead deep into Tor. Hackers were not limited to just one letter. Skype attacker pretending to be an employee of the Association for computing machinery, convinced that his Frame though to make international honor society, which required some paperwork. Kodric believed.
By installing a Trojan on Kodriс's computer hackers were able to obtain direct access to the hot wallet of the exchange. The logs show that the attacker, under the account of Kodric, gained access to the server LNXSRVBTC, where he kept the wallet file.dat, and the DORNATA server where the password was stored. Then the servers were redirected to a certain IP address that belongs to one of the providers of Germany.
There are still no official reports of arrests in this case. Obviously, the case is complicated by the fact that the hackers are outside the UK, and the investigation has to cooperate with law enforcement agencies in other countries.
2. GateHub $9.5 mln (XRP), June 1th, 2019
Hackers have compromised nearly 100 XRP Ledger wallets on cryptocurrency wallet service GateHub. The incident was reported by GateHub in a preliminary statement on June 6.
XRP enthusiast Thomas Silkjær, who first noticed the suspicious activity, estimates that the hackers have stolen nearly $10 million worth of cryptocurrency (23,200,000 XRP), $5.5 million (13,100,000 XRP) of which has already been laundered through exchanges and mixer services.
GateHub notes that it is still conducting an investigation and therefore cannot publish any official findings. Also, GateHub advises victims to make complaints to the relevant authorities of their jurisdiction.
3. Tether, $30.9 mln (USDT), November 19th, 2017
Tether created a digital currency called "US tokens" (USDT) — they could be used to trade real goods using Bitcoin, Litecoin and Ether. By depositing $1 in Tether, the user received 1 USD, which can be converted back into fiat. On November 19, 2017, the attacker gained access to the main Tether wallet and withdrew $ 30.9 million in tokens. For the transaction, he used a Bitcoin address, which means that it was irreversible.
To fix the situation, Tether took action by which the hacker was unable to withdraw the stolen money to fiat or Bitcoin, but the panic led to a decrease in the value of Bitcoin.
4. Ethereum, $31 mln (ETH), July 20th, 2017
On July 20, 2017, the hacker transferred 153,037 Ethers to $31 million from three very large wallets owned by SwarmCity, Edgeless Casino and Eternity. Unknown fraudster managed to change the ownership of wallets, taking advantage of the vulnerability with multiple signatures.
First, the theft was noticed by the developers of SwarmCity.
Further events deserve a place in history: "white hackers" returned the stolen funds, and then protected other compromised accounts. They acted in the same way as criminals, who stole funds from vulnerable wallets — just not for themselves. And it all happened in less than a day.
5. Dao (Decentralized Autonomous Organization) $70 mln (ETH), June 18th, 2016
On June 18, 2016, members of the Ethereum community noticed that funds were being drained from the DAO and the overall ETH balance of the smart contract was going down. A total of 3.6 million Ether (worth around $70 million at the time) was drained by the hacker in the first few hours. The attack was possible because of an exploit found in the splitting function. The attackes withdrew Ether from the DAO smart contract multiple times using the same DAO Tokens. This was possible due to what is known as a recursive call exploit.
In this exploit, the attacker was able to "ask" the smart contract (DAO) to give the Ether back multiple times before the smart contract could update its own balance. There were two main faults that made this possible: the fact that when the DAO smart contract was created the coders did not take into account the possibility of a recursive call, and the fact that the smart contract first sent the ETH funds and then updated the internal token balance.
It's important to understand that this bug did not come from Ethereum itself, but from this one application that was built on Ethereum. The code written for the DAO had multiple bugs, and the recursive call exploit was one of them. Another way to look at this situation is to compare Ethereum to the Internet and any application based on Ethereum to a website: if a website is not working, it doesn't mean that the Internet is not working, it simply means that one website has a problem.
The hacker stopped draining the DAO for unknown reasons, even though they could have continued to do so.
The Ethereum community and team quickly took control of the situation and presented multiple proposals to deal with the exploit. In order to prevent the hacker from cashing in the Ether from his child DAO after the standard 28 days, a soft-fork was voted on and came very close to being introduced. A few hours before it was set to be released, a few members of the community found a bug with the implementation that opened a denial-of-service attack vector. This soft fork was designed to blacklist all the transactions made from the DAO.
6. NiceHash, 4736.42 (BTC), December 6th, 2017
NiceHash is a Slovenian cryptocurrency hash power broker with integrated marketplace that connects sellers of hashing power (miners) with buyers of hashing power using the sharing economy approach.
On December 6, 2017, the company's servers became the target of attack. At first, Reddit users reported that they could not access their funds and make transactions — when they tried to log in, they were shown a message about a service interruption. In the end, it became known that the service had undergone a major cyberattack and 4736,42 Bitcoins disappeared without a trace.
Despite heavy losses, NiceHash was able to continue working, but CEO and founder Marco Koval resigned, giving way to a new team. The company managed to maintain the trust of investors and began to strengthen the protection of its systems.
7. Mt.Gox, 850000 (BTC), June 19th, 2011
The Hacking Of Mt.Gox was one of the biggest Bitcoin thefts in history. It was the work of highly professional hackers using complex vulnerabilities.
A hacker (or a group of hackers) allegedly gained access to a computer owned by one of the auditors and used a security vulnerability to access Mt.Gox servers, then changed the nominal value of Bitcoin to 1 cent per coin.
Then they brought out about 2000 BTC. Some customers, without knowing it, conducted transactions at this low price, a total of 650 BTC, and despite the fact that the hacking hit the headlines around the world, no Bitcoin could be returned.
To increase investor confidence, the company has compensated all of the stolen coins, placed most of the remaining funds in offline storage, and the next couple of years was considered the most reliable Bitcoin exchanger in the world.
However, it was only an illusion of reliability.
The problems of the organization were much more serious, and the management probably did not even know about them.
CEO of Mt.Gox, Mark Karpeles, was originally a developer, but over time he stopped delving into technical details, basking in the rays of glory — because he created the world's largest platform for cryptocurrency exchange. At that time Mt.Gox handled over 70% of all Bitcoin transactions.
And, of course, there were those who wanted to take advantage of the technological weakness of the service. At some point, hackers made it so that Bitcoins could be bought at any price, and within minutes millions of dollars worth of coins were sold — mostly for pennies. World prices for Bitcoin stabilized in a few minutes, but it was too late.
As a result, Mt.Gox lost about 850,000 Bitcoins. The exchange had to declare bankruptcy, hundreds of thousands of people lost money, and the Japanese authorities arrested CEO Mark Karpeles for fraud. He pleaded not guilty and was subsequently released. In 2014, the authorities restored some of the Bitcoins remaining at the old addresses, but did not transfer them to the exchange, and created a trust to compensate for the losses of creditors.
8. Coincheck, $530 mln, January 26th, 2018
The sum was astonishing, and even surpassed the infamous Mt.Gox hack.
While Mt.Gox shortly filed for bankruptcy following the hack, Coincheck has surprisingly remained in business and was even recently approved as a licensed exchange by Japan’s Financial Services (FSA).
Coincheck was founded in 2014 in Japan and was one of the most popular cryptocurrency exchanges in the country. Offering a wide variety of digital assets including Bitcoin, Ether, LISK, and NEM, Coincheck was an emerging exchange that joined the Japan Blockchain Association.
Since Coincheck was founded it 2014, it was incidentally not subject to new exchange registration requirements with Japan’s FSA — who rolled out a framework after Mt. Gox –, and eventually was a contributing factor to its poor security standards that led to the hack.
On January 26th, 2018, Coincheck posted on their blog detailing that they were restricting NEM deposits and withdrawals, along with most other methods for buying or selling cryptocurrencies on the platform. Speculation arose that the exchange had been hacked, and the NEM developers issued a statement saying they were unaware of any technical glitches in the NEM protocol and any issues were a result of the exchange’s security.
Coincheck subsequently held a high-profile conference where they confirmed that hackers had absconded with 500 million NEM tokens that were then distributed to 19 different addresses on the network. Totaling roughly $530 million at the time — NEM was hovering around $1 then — the Coincheck hack was considered the largest theft in the industry’s history.
Coincheck was compelled to reveal some embarrassing details about their exchange’s security, mentioning how they stored all of the NEM in a single hot wallet and did not use the NEM multisignature contract security recommended by the developers.
Simultaneously, the NEM developers team had tagged all of the NEM stolen in the hack with a message identifying the funds as stolen so that other exchanges would not accept them. However, NEM announced they were ending their hunt for the stolen NEM for unspecified reasons several months later, and speculation persisted that hackers were close to cashing out the stolen funds on the dark web.
Mainstream media covered the hack extensively and compared it to similar failures by cryptocurrency exchanges in the past to meet adequate security standards. At the time, most media coverage of cryptocurrencies was centered on their obscure nature, dramatic volatility, and lack of security. Coincheck’s hack fueled that narrative considerably as the stolen sum was eye-popping and the cryptocurrency used — NEM — was unknown to most in the mainstream.
NEM depreciated rapidly following the hack, and the price fell even more throughout 2018, in line with the extended bear market in the broader industry. Currently, NEM is trading at approximately $0.07, a precipitous fall from ATH over $1.60 in early January.
The extent of the Coincheck hack was rivaled by only a few other hacks, notably the Mt.Gox hack. While nominally Coincheck is the largest hack in the industry’s history, the effects of Mt.Gox were significantly more impactful since the stolen funds consisted only of Bitcoin and caused a sustained market correction as well as an ongoing controversy with the stolen funds and founder. Moreover, Mt.Gox squandered 6% of the overall Bitcoin circulation at the time in a market that was much less mature than it is today.
Despite the fallout, Coincheck is now fully operational and registered with Japan’s FSA.
As practice shows, people make mistakes and these mistakes can cost a lot. Especially, when we talk about mad cryptoworld. Be careful and keep your private keys in a safe place.

Let's get serious for a minute

Allright, to start up I'm possibly pro fork and shurely against what btc is turning into. (settlement layer bullshit)
Still, I had a few concerns about this fork, while reading around this thread it seems you guys want to make an altcoin with the name bitcoin... I read about switching the algo or adding an 2nd asic resistant algo, new logo, do you guys really want to fork btc or what ?!?
My idea of a fork is getting 51% of the hashrate (I can contribute 10-20ths for a limited time with my s2s and same gen equipment) and getting the control of the REAL btc back from core, NOT making another coin...
To get support we need to make something better than what you had before, how do you think you'll get the Chinese miners with an algo that will need them to change their asics? And we've worked so hard to get the name known and people to use btc, why would we want to change that?
Anyways, that's what I think, the initiative to fork is great to take back control over the mainchain, but we need to make the exact same replica with minor changes (blocksize for example), not a whole new logo, chain etc.(no pun intended)
Cheers, I'd be happy to discuss more about this if I'm not downvoted to oblivion :)
Q.
EDIT : after seeing the replies, it seems this fork doesn't coincide with what I think is a solution, I'll keep it in mind but I won't switch back on 1w/ghs HW with my 0,2eukw to support it (as of now)
I wish you all the best and hope I change my mind when you have a more precise roadmap :)

My growing collection of info about NEO

It can be very time consuming to keep up to date on a single blockchain project let alone multiple ones. If you just heard about NEO a few weeks ago it would be impossible catch up on past occurrences due to high volume of Reddit posts and articles made on the project. I’m going to try and simplify the past, present and future as much as I can into one well thought-out post. I hope I can be helpful to anyone who has been investigating like myself. I will include sources with all of my research.

Key notes from the White Paper http://docs.neo.org/en-us/
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries. On the NEO blockchain, users are able to register, trade, and circulate multiple types of assets. Proving the connection between digital and physical assets is possible through digital identity. Assets registered through a validated digital identity are protected by law.
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form. The more mature digital identity system is based on the PKI (Public Key Infrastructure) X.509 standard. In NEO, we will implement a set of X.509 compatible digital identity standards. This set of digital identity standards, in addition to compatible X.509 level certificate issuance model, will also support Web Of Trust point-to-point certificate issuance model. Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion WILL NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism. At present, quantum computers do not have the ability to quickly solve the Shortest Vector Problem (SVP) and the Closest Vector Problem (CVP), which is considered to be the most reliable algorithm for resisting quantum computers.
Reasons for choosing dBFT over PoW and PoS:
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 3.67 average American homes, which amounts to about 3000 times more than a comparable Credit Card settlement.
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion. This confusion is likely the source of the rumour about Antshares and Alibaba having a connection. Onchain and NEO are separate entities who are intimately related via cross-chain communications and similar designs.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses. It is here where the Da HongFei and Erik Zhang, entered the hyperbolic time chamber that is now known as Fabric, a platform by Hyperledger for distributed ledger solutions, and has consequently helped them to develop many aspects underpinning the design of DNA.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO for you to “go to the moon on your rocket powered lambos”. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
--Key Observations--
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
Crowdsale statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
Final Thoughts
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.

“As a leading open-source contributor in China’s blockchain community, Onchain shares the same values as the Linux Foundation and the Hyperledger project intrinsically. We believe international collaboration plus local experience are key to the adoption of distributed ledger technology in China; we are also very excited to see other Chinese blockchain startups join Hyperledger and look forward to adding our combined expertise to the project.” Da Hongfei, Founder and CEO of Onchain

Da Hongfei quotes
"There is no direct cooperation between Alibaba and NEO/Onchain, other than their mailbox service is using Law Chain to provide attested email service. In terms of Microsoft, yes we have cooperation with Microsoft China because NEO is built with C# and .NET Core, and NeoContract is the first in the world to support writing smart contract with C#"

"We have pretty good communication with government, with regulators. They don't have any negative impression with NEO and they like our technology and the way we deal with things. Regulation is not an issue for us"

“Before they started cleaning up the market, I was asked for information and suggestions” “I do not expect the government to call me in the short-term and say, ‘Let’s use NEO as the blockchain technology infrastructure of China.’ But in the medium term? Why not? I think it’s possible.”
