Debunking: "Blockstream is 3 or 4 developers out of hundreds of developers at Core" - Tone Vays

He says this at 25:50 in this interview whilst making the argument that Bitcoin Core development is decentralised.
Let's check a few things.
First port of call is Github.
There are 32 contributors with over 30 commits. Out of these 32, 8 have made no contributions at all in 2017 so lets drop that number to 24.
There are 10 contributors with over 200 commits.
  1. Wladimir J. van der Laan he is funded by MIT Media Labs Digital Currency initiative.
  2. Pieter Wuille, co-founder of Blockstream.
  3. Matt Corallo. Matt also works for Chaincode Labs.
  4. Corey Fields, funded by MIT Media Labs Digital Currency initiative.
  5. Jonas Schnelli is cited as 'independent'. If anyone has more info on him, that would be nice.
  6. Marco Falke - Chaincode Labs
  7. Luke Dashjr - Blockstream
  8. John Newbery - Chaincode Labs
  9. Alex Morcos - Chaincode Labs founder
  10. Suhas Daftuar - Chaincode Labs founder (199 commits)
So just scratching the surface, this is far from hundreds of developers, and far from a decentralised team. 7 of the top 10 developers of Bitcoin Core work for Blockstream and Chaincode.
Now let's take a quick look at Chaincode. It was self-funded by its founders Alex Morcos and Suhas Daftuar who also started Hudson River Trading in 2002. Here's where it gets interesting. Alex Morcos also participated in funding MIT's Media Labs Digital Currency initiative, which is who funds Wladimir J. van der Laan and Corey Fields. Matt Corallo (Blockstream) is a team member of Chaincode. While everybody is focused on Blockstream, we have Alex Morcos funding 6 of the top 10 developers for sure. Only Jonas Schnelli is uncertain how he is funded.
Call me a tin foil hat wearing crazy man, but this does not look like a decentralised development team to me at all.
Edit: Thanks for all the tips and reddit gold. Honestly, I prefer tips to gold. I now have a year and a half of Reddit gold, and the tips I pay forward to other people, so more useful. But either way, it's appreciated :)

Is it possible to objectively discuss things without getting dragged to the "Dragons Den"?

The computer science debates about the best ways to scale Bitcoin are far too important for us to take “sides”.
“Beating” the other guy doesn’t serve any of us, and it doesn’t serve Bitcoin.
In these discussions we need to be as sure as possible that we are not just winning an argument, or making talking points but that we are factually correct.
One thing everyone should agree on is the need for truthful and factual statements when discussing these important issues.
Unfortunately, the Bitcoin community learned some very bad habits from the world of politics.
[Disclaimer: I do not work for Blockstream and I never have, just as I did not work for Roger Ver the other day when I defended him against a similar baseless attack about Mt.. Gox ]
For example, it is difficult to have any discussion in Bitcoin without someone bringing up the “Dragon’s Den”.
"Dragon’s Den" is brought up as an argument point often by everyone from major minors, to CEOs and analysts.
But what do we really know about “Dragon’s Den”?
What is the full body of evidence regarding the claims about Dragons Den?
Well, it’s pretty simple:
1) One lone LN developer claimed that there was a secret channel used for trolling
2) Someone posted a screenshot showing the existence of the slack channel and some people chatting in it
What is absent from this evidence:
So really, we have CEOs, miners and thousands of people who care passionately about Bitcoin using “Dragon’s Den” as a talking point when really – – – the entire thesis about dragons den comes down to “a guy said”.
One doesn’t even have to be critical of the developer who claimed its existence to have doubts about the story.
If you look carefully, Joseph Poon never even claimed to have first-hand knowledge about dragons den being used for trolling – he didn’t even mention that he ever visited the channel.
One guy saying something doesn’t make it true.
One doesn't even have to think that Joseph is a bad actor (and I don't) maybe he was misinformed, didn't think clearly before making his statement, had a misunderstanding or exaggerated.
There was a Reddit post asking him to clarify but it doesn't seem he did.
So what is Dragon’s Den really?
Honestly my best educated guess is that the slack channel simply existed as a place for like-minded individuals to discuss topics and opinions they share an interest in.
After it was revealed to the public, the channel was opened to a number of interested/concerned community members to review including me. This was the first time I knew about or entered the channel. What I saw was pretty similar to the regular Slack. Bias against BU? Of course? Bias in favor of the core roadmap? Sure? An organized trolling campaign? Doubtful.
My guess is that the channel was similar before it became public.
Now it is possible that, as part of an elaborate ruse, participants in the channel have gone and created a new double secret channel where the real trolling is being organized and are still participating in the existing “Dragon’s Den” channel as some sort of theater to throw people off their trail and fool someone like me into posting this.
Maybe, maybe, maybe
But I doubt it. Occams Razor is a good explanation – the most likely explanation is that it simply people who are like-minded gathering together
Just as the most likely explanation for a lot of behavior in Bitcoin is the simple one.
I don't think Gavin is in the CIA or Roger is secretly trying to harm Bitcoin or Blockstream is involved in some conspiracy to destroy Bitcoin with AXA and I don't think Bitmain purposely intended to shut down miners (but the risk was still real) and I don't think Greg Maxwell works for the CIA either.
People have human faults, they mess up, they are self interested etc. Occasionally they will be behind some elaborate ruse, but usually behavior comes down to just people being people.
What about the trolling?
Again absence any evidence I think the simplest explanation is that like-minded people hanging around in the channel are likely to react in similar manners to various news and tweets.
It’s most likely like “Hey did you see this ridiculous argument John Doe just tweeted?" and then a number of like-minded people make comments on that post. Could this be considered organized trolling? Maybe. Same way posting a tweet on one or the other Reddit sub will cause a dozen people to comment...this seems like organized trolling.
Having been attacked, criticized and trolled by many of the same people who are very active in that channel I know how it feels: even half a dozen people can easily make you feel overwhelmed by attackers. Between misconceptions, logical fallacies, name-calling, retweets, reposts and comments for multiple people you can feel like Boromir in the first Lord of the Rings movie with arrow after arrow shot at you.
But really – this is just part of the way the Internet works.
I once even found myself banned from the entire Slack in question. I annoyed people with my continual calls for compromise as well as occasionally defending people from exactly the type of unfair or inaccurate attack I’m talking about here.
Fortunately, cooler heads prevailed, I put my differences aside with the people at in the channel and since then have had a lot of productive and mutually respectful discussions about this important technology.
But core runs this!
This is the thing, they really don’t. I tried to get this point across in a recent blog post.
Down With Bitcoin Core (as a noun used to describe people)
I know it’s frustrating, and I used to feel the same way as many BU supporters in thinking that “core” was one monolithic, like-minded entity. ** It’s really not. It's just not factual to look at it this way**
*Only after a lot of time spending a lot of time meeting with and discussing issues with numerous core and non-core developers did I come to this opinion. *
I now think that it is only fair for us to judge individual people on the individual actions that they take. Not actions taken by a group.
Worse yet: Some core developers even use this word “core” as a noun to describe people when it suits them. This is equally wrong. Individual people and only individual people should be held accountable for the actions that they actually taken the words that they actually say.
If we do that, it’s harder to argue.
Groups are easy to hate. It’s very easy to discuss to prescribe opinions or characteristics on “Republicans” or “liberals” or "core" or "btc". If you are running for office, it’s a great idea to use these types of terms: they seek to divide and drive wedges.
The world of politics is not that simple: on major issues ranging from the drug war to war, foreign policy and taxes there are vast differences between people who carry the various political labels.
An open source project, particularly one as diverse as Bitcoin, has much more nuance than this even.
There is definitely no universal “core” opinion.
“Core developers” include a wide variety of people: Gavin Andresen, Satoshi Nakamoto, Greg Maxwell, Matt Corallo, Alex Marcos, Peter Todd, Vladimir and many others.
It just isn’t accurate or fair to put all people in the same category.
What happens if we do start holding individual people accountable for their actions?
Well, for one thing, it makes it a lot harder to argue against broad ideas such as “core believes X” or “core failed to X”.
If someone claims that the “Dragon’s Den” is some sort of effort by “core”, then the first question should be “Who specifically do you mean by “core””? As far as I can tell the only contributor to the core software project was active in that particular channel is the moderator.
In fact, it does not seem likely that even more than a couple other actual core developers ever even visited the channel – – let alone used it or engaged in any sort of organized trolling behavior from it. How many core devs total on the high end even visited? Five?
So instead of saying "Dragons Den is a core project to organize trolling" why don't we say "these five people organize trolling"? Well, because it's too damn hard. It's EASY to blame some nameless faceless group, but when you name specific people you usually have to back it up better, so those five people accused would (rightfully) respond "Huh? What evidence do you have of this?"
Bram Cohen was caught in this exact situation. Just by being in this now infamous chat channel it was assumed he was a participant in trolling. Why? Because a guy said that the channel exists for trolling
If someone has visions of Vladimir or Greg Maxwell sitting around this particular Slack channel planning troll campaigns – – the facts and evidence simply don’t show this to be reflective of reality.
So what should we do next?
This argument isn’t going to be solved by one post.
But what we can all do is work together to discuss things in his fair and accurate of a way as possible.
This means holding actual people responsible for actual actions they do. If you don't like the core roadmap, debate it with Nullc, if you don't agree with the people who signed it, take it up with them. If you don't think the peer review process is fair and objective, contribute technically to the discussion. If you don't like the "Dragons Den" then take it up with specific people. What this really ends up looking like is that instead of being able to say "Dragons Den is a massive troll army run by core" it ends up more like "BTCDrak and MrHodl and Alp are in a channel and I don't like what they tweeted". That second statement doesn't have the bite of the first....but it's true.
Working for better standards also means we should really avoid claims about either "side" unless they are backed by evidence and relevant to the discussion.
In fact, we shouldn’t even be having “sides” at all.
We are here to change the world. No one likes the bickering. Many don't participate...but almost all of us support it at some point. Whether it's up-voting a divisive post, sharing a meme attacking the other guys or using terms designed to place people in camps, we contribute even when we don't mean to.
What would happen if we all decided to no longer participate in division? What if we down voted every comment that attacks individuals or which is divisive and we upvoted everything positive?
What if we kept scientific debate more scientific?
Every piece of data and information in this discussion should be analyzed independently. Independent of the source ended up dependent of what our own motivations or narrative might be.
Anytime we engage in using terms designed to “beat” the other side red division, we don’t win paragraph we win and Bitcoin wins by us all working together to be as accurate and fair as possible.

I keep reading people say bitcoin development is stalled

But in practice there's more going on right now than there's ever been in the last few years. You just have to look in the right places. Here's a few days of documented github activity from the bitcoin slack and I've a feeling there are hundreds more people working on Bitcoin projects outside of the work being done by core:

If a pruning node ends up in a state where it has very few blocks on disk, then a node could fail to start up in VerifyDB. This pull changes the behavior for pruning nodes, so that we will just not bother trying to check blocks that have been pruned.
I don't expect this edge case to be triggered much in practice currently; this is a preparatory commit for segwit (to deal with the case of pruning nodes that upgrade after segwit activation).

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).


Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups. added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)


Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.


Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.


Meet our 17th voting service provider: It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.


The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.


Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)


We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)


August issue of Decred Journal was translated to Russian. Many thanks to @DZ!
Rency cryptocurrency ratings published a report on Decred and incorporated a lot of feedback from the community on Reddit.
September issue of Chinese CCID ratings was published (snapshot), Decred is still at the bottom.

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Adam Back says "Blockstream Core" is a conspiracy theory. What do you think?

Trying to rebut the suggestion that Blockstream has a conflict of interest owing to its influence over Core development, Adam Back claimed:
I dont think anyone other [than] conspiracy theorists even accepts that "blockstream core" exists! blockstream has 1.5x full time developers working on bitcoin ...
Here are some facts supporting the idea Blockstream and Core are in bed with each other and can be regarded together as "Blockstream Core":
Core developers founded Blockstream
Blockstream was founded in 2014 by Bitcoin Core developers Gregory Maxwell, Dr. Pieter Wuille, Matt Corallo, Jorge Timón and Mark Friedenbach, as well as several non-Bitcoin Core developers including hashcash inventor Dr. Adam Back and venture capitalist Austin Hill. (source)
Also Luke Dashjr source
The Core devs are still listed as part of Blockstream's team.
At least 10 Core devs work for Blockstream (or 9 if you exclude Adam Back - should we?)
  1. Gregory Maxwell, 2. Matt Corallo, 3. Jorge Timon, 4. Mark Friedenbach, 5. Patrick Strateman, 6. Warren Togami, 7. Adam Back, 8. Pieter Wuille, 9. Gregory Sanders, 10. Glenn Willen Edit: 11. Luke Dashjr
Sources: Mike Hearn and Aaron van Wirdum, see also Blockstream.
Core's contentious addition to Bitcoin, Segwit, is the baby of a Blockstream employee, Pieter Wuille: Blockstream are vocal in their advocacy of Segwit adoption.
The Hong Kong Agreement
The Hong Kong roundtable agreement was intended to prevent miners forking to Bitcoin Classic and ensure the adoption of Segwit. Several Blockstream personnel signed, but as Core members. Except Adam, who it is widely understood wished to sign as "individual", but changed this to "Blockstream" at the miners' insistence, the miners clearly regarding Blockstream itself as party to the agreement and underlining the common perception that Blockstream has significant influence over the development of Core code and that the two are intertwined.
Incidentally, anyone know who paid Adam Back's and the Core developers' expenses?
It seems to me the facts above strongly suggest there is enough of a connection between Blockstream and Core that it is perfectly justifiable to regard them for practical purposes as "Blockstream Core".
Adam's statement that Blockstream has 1.5x full time developers working on bitcoin may or may not be true in some narrow sense, but when 9 or 10 Core devs work for Blockstream his statement is hardly full and frank disclosure. It smacks of trying to hide something: what is his game?
Perhaps he is afraid that if everyone realises "Blockstream Core" truly describes reality then everyone will also realise Core and its reference client may have been captured for Blockstream's private profit?
Anyway, do you have any more facts or observations? For example, do Core devs have Blockstream shares or options on shares? What influence does Blockstream have on Core and vice versa and how is that influence exercised?
And do you agree with Adam that the idea of "Blockstream Core" is just a conspiracy theory?

Decred Journal — May 2018

Note: New Reddit look may not highlight links. See old look here. A copy is hosted on GitHub for better reading experience. Check it out, contains photo of the month! Also on Medium


dcrd: Significant optimization in signature hash calculation, bloom filters support was removed, 2x faster startup thanks to in-memory full block index, multipeer work advancing, stronger protection against majority hashpower attacks. Additionally, code refactoring and cleanup, code and test infrastructure improvements.
In dcrd and dcrwallet developers have been experimenting with new modular dependency and versioning schemes using vgo. @orthomind is seeking feedback for his work on reproducible builds.
Decrediton: 1.2.1 bugfix release, work on SPV has started, chart additions are in progress. Further simplification of the staking process is in the pipeline (slack).
Politeia: new command line tool to interact with Politeia API, general development is ongoing. Help with testing will soon be welcome: this issue sets out a test plan, join #politeia to follow progress and participate in testing.
dcrdata: work ongoing on improved design, adding more charts and improving Insight API support.
Android: design work advancing.
Decred's own DNS seeder (dcrseeder) was released. It is written in Go and it properly supports service bit filtering, which will allow SPV nodes to find full nodes that support compact filters.
Ticket splitting service by @matheusd entered beta and demonstrated an 11-way split on mainnet. Help with testing is much appreciated, please join #ticket_splitting to participate in splits, but check this doc to learn about the risks. Reddit discussion here.
Trezor support is expected to land in their next firmware update.
Decred is now supported by Riemann, a toolbox from James Prestwich to construct transactions for many UTXO-based chains from human-readable strings.
Atomic swap with Ethereum on testnet was demonstrated at Blockspot Conference LATAM.
Two new faces were added to contributors page.
Dev activity stats for May: 238 active PRs, 195 master commits, 32,831 added and 22,280 deleted lines spread across 8 repositories. Contributions came from 4-10 developers per repository. (chart)


Hashrate: rapid growth from ~4,000 TH/s at the beginning of the month to ~15,000 at the end with new all time high of 17,949. Interesting dynamic in hashrate distribution across mining pools: share went down from 55% to 25% while F2Pool up from 2% to 44%. [Note: as of June 6, the hashrate continues to rise and has already passed 22,000 TH/s]
Staking: 30-day average ticket price is 91.3 DCR (+0.8), stake participation is 46.9% (+0.8%) with 3.68 million DCR locked (+0.15). Min price was 85.56. On May 11 ticket price surged to 96.99, staying elevated for longer than usual after such a pump. Locked DCR peaked at 47.17%. jet_user on reddit suggested that the DCR for these tickets likely came from a miner with significant hashrate.
Nodes: there are 226 public listening and 405 normal nodes per Version distribution: 45% on v1.2.0 (up from 24% last month), 39% on v1.1.2, 15% on v1.1.0 and 1% running outdaded versions.


Obelisk team posted an update. Current hashrate estimate of DCR1 is 1200 GH/s at 500 W and may still change. The chips came back at 40% the speed of the simulated results, it is still unknown why. Batch 1 units may get delayed 1-2 weeks past June 30. See discussions on decred and on siacoin.
@SiaBillionaire estimated that 7940 DCR1 units were sold in Batches 1-5, while Lynmar13 shared his projections of DCR1 profitability (reddit).
A new Chinese miner for pre-order was noticed by our Telegram group. Woodpecker WB2 specs 1.5 TH/s at 1200 W, costs 15,000 CNY (~2,340 USD) and the initial 150 units are expected to ship on Aug 15. (pow8.comtranslated)
Another new miner is iBelink DSM6T: 6 TH/s at 2100 W costing $6,300 ( Shipping starts from June 5. Some concerns and links were posted in these two threads.


A new mining pool is available now: It uses PPLNS model and takes 1% fee.
Another infrastructure addition is, a newly audited stake pool with 0.8% fee. There are a total of 14 stake pools now.
Exchange integrations:
OpenBazaar released an update that allows one to trade cryptocurrencies, including DCR.
@i2Rav from i2trading is now offering two sided OTC market liquidity on DCUSD in #trading channel.
Paytomat, payments solution for point of sale and e-commerce, integrated Decred. (missed in April issue)
CoinPayments, a payment processor supporting Decred, developed an integration with @Shopify that allows connected merchants to accept cryptocurrencies in exchange for goods.


New merchants:
An update from VotoLegal:
michae2xl: Voto Legal: CEO Thiago Rondon of Appcívico, has already been contacted by 800 politicians and negotiations have started with four pre-candidates for the presidency (slack, source tweet)
Blockfolio rolled out Signal Beta with Decred in the list. Users who own or watch a coin will automatically receive updates pushed by project teams. Nice to see this Journal made it to the screenshot!
Placeholder Ventures announced that Decred is their first public investment. Their Investment Thesis is a clear and well researched overview of Decred. Among other great points it noted the less obvious benefit of not doing an ICO:
By choosing not to pre-sell coins to speculators, the financial rewards from Decred’s growth most favor those who work for the network.
Alex Evans, a cryptoeconomics researcher who recently joined Placeholder, posted his 13-page Decred Network Analysis.


@Dustorf published March–April survey results (pdf). It analyzes 166 responses and has lots of interesting data. Just an example:

Community Discussions

Community stats: Twitter 39,118 (+742), Reddit 8,167 (+277), Slack 5,658 (+160). Difference is between May 5 and May 31.
Reddit highlights: transparent up/down voting on Politeia, combining LN and atomic swaps, minimum viable superorganism, the controversial debate on Decred contractor model (people wondered about true motives behind the thread), tx size and fees discussion, hard moderation case, impact of ASICs on price, another "Why Decred?" thread with another excellent pitch by solar, fee analysis showing how ticket price algorithm change was controversial with ~100x cut in miner profits, impact of ticket splitting on ticket price, recommendations on promoting Decred, security against double spends and custom voting policies.
@R3VoLuT1OneR posted a preview of a proposal from his company for Decred to offer scholarships for students.
dcrtrader gained a couple of new moderators, weekly automatic threads were reconfigured to monthly and empty threads were removed. Currently most trading talk happens on #trading and some leaks to decred. A separate trading sub offers some advantages: unlimited trading talk, broad range of allowed topics, free speech and transparent moderation, in addition to standard reddit threaded discussion, permanent history and search.
Forum: potential social attacks on Decred.
Slack: the #governance channel created last month has seen many intelligent conversations on topics including: finite attention of decision makers, why stakeholders can make good decisions (opposed to a common narrative than only developers are capable of making good decisions), proposal funding and contractor pre-qualification, Cardano and Dash treasuries, quadratic voting, equality of outcome vs equality of opportunity, and much more.
One particularly important issue being discussed is the growing number of posts arguing that on-chain governance and coin voting is bad. Just a few examples from Twitter: Decred is solving an imagined problem (decent response by @jm_buirski), we convince ourselves that we need governance and ticket price algo vote was not controversial, on-chain governance hurts node operators and it is too early for it, it robs node operators of their role, crypto risks being captured by the wealthy, it is a huge threat to the whole public blockchain space, coin holders should not own the blockchain.
Some responses were posted here and here on Twitter, as well as this article by Noah Pierau.


The month of May has seen Decred earn some much deserved attention in the markets. DCR started the month around 0.009 BTC and finished around 0.0125 with interim high of 0.0165 on Bittrex. In USD terms it started around $81 and finished around $92, temporarily rising to $118. During a period in which most altcoins suffered, Decred has performed well; rising from rank #45 to #30 on Coinmarketcap.
The addition of a much awaited KRW pair on Upbit saw the price briefly double on some exchanges. This pair opens up direct DCR to fiat trading in one of the largest cryptocurrency markets in the world.
An update from @i2Rav:
We have begun trading DCR in large volume daily. The interest around DCR has really started to grow in terms of OTC quote requests. More and more customers are asking about trading it.
Like in previous month, Decred scores high by "% down from ATH" indicator being #2 on onchainfx as of June 6.

David Vorick (@taek) published lots of insights into the world of ASIC manufacturing (reddit). Bitmain replied.
Bitmain released an ASIC for Equihash (archived), an algorithm thought to be somewhat ASIC-resistant 2 years ago.
Three pure PoW coins were attacked this month, one attempting to be ASIC resistant. This shows the importance of Decred's PoS layer that exerts control over miners and allows Decred to welcome ASIC miners for more PoW security without sacrificing sovereignty to them.
Upbit was raided over suspected fraud and put under investigation. Following news reported no illicit activity was found and suggested and raid was premature and damaged trust in local exchanges.

Bitcoin dev IRC meeting in layman's terms (2016-01-14)

Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms. Link to last summarisation
Please bear in mind I'm not a developer so some things might be incorrect or plain wrong. There are no decisions being made in these meetings, but since a fair amount of devs are present it's a good representation. Copyright: Public domain


Main topics



BIP 9 Currently softforks have been done by the isSuperMajority mechanism, meaning when 95% of the last 1000 blocks have a version number higher than X the fork is deployed. A new way of doing this is currently being worked on and that uses all bits of the version number, appropriately being called versionbits. So instead of a fork happening when the version is larger than (for example) 00000000011 (3), a fork happens when (for example) the 3rd bit is up (so 00100000011). This way softforks can be deployed simultaneous and independent of each other.

meeting comments

Morcos is volunteering to take over championing this proposal as CodeShark and Rusty are busy on other things. He'll review both implementations and then decide on which implementation he'll base his work upon. He notes that if non-core implementations are trying to do something else (and are using nVersion for their signaling) while segregated witness is being deployed, not conflicting will be important so users of other versions can also support segregated witness. If there's an agreement with this approach it's necessary that versionbits is ready before the segregated witness deployment. jtimon has some suggestions to make the implementation less complicated and more flexible.

meeting conclusion

Morcos will champion the new reference implementation for BIP9: Versionbits.

Status of segregated witness


Segregated witness changes the structure of transactions so that the signatures can be separated from the rest of the transactions. This allows for bandwidth savings for relay, pruning of old signatures, softforking all future script changes by introducing script versions and solves all unintentional forms of malleability. During the last scaling bitcoin conference Pieter Wuille presented a way of doing this via a softfork, and proposed increasing the maximum amount of transactions in a block by discounting signature data towards the total blocksize. Segregated witness is part of the capacity increase roadmap for bitcoin-core. More detailed explanations: - By Pieter Wuille at the San Francisco bitcoin developer meetup (more technical) - By Andreas Antonopoulos in the let's talk bitcoin podcast (less technical)

meeting comments

Segnet, the testnet for segregated transactions, will be going to it's 3rd version soon. Luke-Jr has assigned all the segregated witness BIPs to a 14x range. Currently there are 4 BIPs: 141, 142, 143 and 144.

Status of 0.12 bitcoin-core release


Bitcoin Core 0.12 is scheduled for release around February and introduces a lot of fixes and improvements. (release notes) There's a release candidate 0.12rc1 available at

meeting comments

Luke-Jr feels PR's #7149, #7339 and #7340 should have been in 0.12, but are now really late and possibly impractical to get in. For gitian builders: 0.12rc1's osx sig attach descriptor fails due to a missing package (that's not actually needed). Rather than using the in-tree descriptor, use the one from #7342. This is fixed for rc2. "fundrawtransaction" and "setban" should be added to the release notes. At some point it makes more sense to document these commands elsewhere and link to it in the release notes, as they've become very lengthy. Wumpus thinks the release notes have too much details, they're not meant to be a substitute for documentation.

meeting conclusion

Close PR #7142 as it's now part of #7148 Everyone is free to improve on the release notes, just submit a PR.

consensus code encapsulation (libconsensus)


Satoshi wasn't the best programmer out there, which leaves a pretty messy code. Ideally you'd have the part of the code that influences the network consensus separate, but in bitcoin it's all intertwined. Libconsensus is what eventually should become this part. This way people can more easily make changes in the non-consensus part without fear of causing a network fork. This however is a slow and dangerous project of moving lots of code around.

meeting comments

jtimon has 4 libconsensus related PRs open, namely #7091 #7287 #7311 and #7310 He thinks any "big picture branch" will be highly unreadable without merging something like #7310 first. The longest "big picture branch" he currently has is He'll document the plan and "big picture" in stages: 1. have something to call libconsensus: expose verifyScript. (Done) 2. put the rest of the consensus critical code, excluding storage in the same building package (see #7091) 3. discuss a complete C API for libconsensus 4. separate it into a sub-repository Wumpus notes he'd like to start with 3 as soon as possible as an API would be good to guide this.

meeting conclusion

review #7091 #7287 #7311 and #7310

Locktime PRs


BIP 68 Consensus-enforced transaction replacement signaled via sequence numbers. BIP 112 CHECKSEQUENCEVERIFY. BIP 113 Median time-past as endpoint for lock-time calculations. In short: BIP 68 changes the meaning of the sequence number field to a relative locktime. BIP 112 makes that field accessible to the bitcoin scripting system. BIP 113 enables the usage of GetMedianTimePast (the median of the previous 11 blocks) from the prior block in lock-time transactions.

meeting comments

We need to make a choice between 2 implementations, namely #6312 and #7184. PR #7184 is a result of the CreateNewBlock optimisations not being compatible with #6312. jtimon thinks it could be merged relatively soon as #7184 is based on #6312 which has plenty of testing and review.

meeting conclusion

Close #6312 in favor of #7184. Morcos will fix the open nits on #7184 btcdrak will update the BIP-text

The latest bitcoin core IRC meeting is actually blockstream IRC meeting
Just find something amazing, open this link, there are 10 participants.
Gregory Maxwell, Pieter Wuille,Matt Corallo,Alex Morcos, Wladimir van der Laan,Suhas Daftuar,Luke Dashjr, Marco Falke,Glenn Willen,Bryan Bishop
These people are all from blockstream, companies founded by blockstream employee and allies(shows everywhere there is blockstream) of blockstream
Gregory Maxwell, Pieter Wuille, Matt Corallo, Luke Dashjr, Glenn Willen are from blockstream, Matt Corallo,Suhas Daftuar,Alex Morcos are from Chaincode Labs, a joint group of blockstream(Matt is in both), Bryan Bishop only shows with blockstream. Marco Falke is introduced by Wladimir,we know that Wladimir and gmax are the most importan guys who are restricting the block size, they are allies from the very beginning.
Bitcoin Core IRC meeting, is it really a proper name? What about call it blockstream IRC meeting? It looks like blockstream developers are making a public show every week like a bunch of clowns to please the public and make people believe they are open, while we do not know what happens in their own private show. Personally, I will not be surprised at all that one day this public show suddenly vanish.

Bitcoin dev IRC meeting in layman's terms (2016-01-07)

Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms. Link to last summarisation
Please bear in mind I'm not a developer so some things might be incorrect or plain wrong. There are no decisions being made in these meetings, but since a fair amount of devs are present it's a good representation. Copyright: Public domain
link to this week logs Meeting minutes by meetbot
Main topics discussed where:
0.12 Release candidate Detailed roadmap for next projects
Short topics/notes
Gmaxwell has asked Luke-Jr to take over as BIP-editor. He'll be working on clearing up the back-log. He mailed the mailinglist for information.
All platforms seem to compile bitcoin with C++11 now. Travis still needs a C++11 compiler, which cfields will enable.
Segnet will do a backwards incompatible change soon, to change the commitment structure.
0.12 Release candidate
Bitcoin Core 0.12 is scheduled for release around February and introduces a lot of fixes and improvements.
It still needs some more info in the release notes. PR's #7151 and #7149 are mentioned to possibly still be included in 0.12 as well as a quick fix for #7098 (to be written). Morcos feels strongly that releasing 0.12 as is, is pretty bad. Due to the smartfee changes stuck transactions should be really rare, but if they happen it's worse than 0.11, as the network more easily "forgets" transactions. PR #7312 "Add RPC call abandontransaction" is proposed by Morcos to be a quick-fix to enable users to make their wallet forget about the inputs to a transaction that's not in the mempool. Better solutions should be build for 0.12.1
Take a look at PR's #7151, #7149 and #7312 Cfields will work on a fix for #7098
Detailed roadmap for next projects
Morcos makes a request for some direction on what sort of timeline projects are on, and what the order of implementation should roughly be. This so there's a concentration of effort and focus. A more clear plan could result in investing resources into the right parts.
Jonasschnelli will work on RBF features for the wallet. Cfields is planning to post a request for comments for a network stack overhaul next week. BIP 9 versionbits is moved back in priority a bit. Libconsensus refactoring needs a scheduled time to do, as well as C++11. Clang format might not be worth it, if so we need to communicate that it won't happen.
Everyone that is working on something that they plan to have finished for 0.13 should send wumpus his proposals, so he can merge it into a plan.

More funds testing water on crypto-related assets

More funds testing water on crypto-related assets

Anthony Pompliano sees an ‘enormous upside’ for returns from direct investment in cryptocurrencies despite the worrying volatility. ALEX FLYNN/BLOOMBERG
Institutional investors, including public pension funds, have begun taking bets on fledgling funds, which invest heavily in cryptocurrency and blockchain-related companies.
But these funds also could invest directly in cryptocurrencies as well, which some industry sources argue are not a viable investment option for institutions, primarily due to volatility and valuation concerns.
In Virginia, the $4.2 billion Fairfax County Employees’ Retirement System and the $1.5 billion Fairfax County Police Officers Retirement System became the first known public pension plan to commit to a dedicated fund that invests primarily in blockchain technology firms. The investments were “deliberately sized to be a small portion of each system’s assets,” Jeff Weiler, the executive director of Fairfax County Retirement Systems, wrote in a February note published on the system’s website. The employees’ fund allocated $10 million and the police fund $11 million, mandates representing less than 1% of each fund.
Both investments were made in the Morgan Creek Blockchain Opportunities Fund, managed by Morgan Creek Digital Assets, a subsidiary of Chapel Hill, N.C.-based Morgan Creek Capital Management LLC.
While 85% of the Morgan Creek fund is invested in blockchain technology firms, up to 15% of the fund can be invested directly into cryptocurrencies, Mr. Weiler wrote, adding that the fund currently “has no exposure to any cryptocurrencies.”
Since June, other unidentified institutions, including a university endowment, hospital system, insurance company and private founda- tion have invested in the fund, said New York-based Anthony Pompliano, founder and partner at Morgan Creek Digital Assets.
Every investor in the fund is under the same structure, where up to 15% of the fund can be allocated to liquid cryptocurrencies, such as bitcoin, Mr. Pompliano said. The Fairfax plans made their allocations to the $40 million fund at the end of the year, he added.
“The fundraising target was $25 million, and we oversubscribed to $40 million. The fund is done fundraising and will not take any more investors,” Mr. Pompliano said.
“That 15% is kind of an artificial cap because we want to make sure we are sizing the liquid investments inside of the portfolio according to the risk-return profile that liquid cryptocurrencies present,” Mr. Pompliano said. Morgan Creek believes that certain cryptocurrencies, “although they are volatile, have enormous upside and, therefore, we want to make sure that we gain exposure to it. But we want to size it correctly within the portfolio.”
The University of Michigan’s $12 billion endowment committed $3 million in June to a dedicated fund investing in crypto-technology companies, which was created by Menlo Park, Calif.-based venture capital firm Andreessen Horowitz, according to agenda materials from the university’s Feb. 21 board of regents meeting.
The fund, CNK Fund 1, also received approval for a follow-on investment of an undisclosed amount, the documents show. Follow-on investments do not require approval, only a report to the board, a university spokesman wrote in a February email, declining to provide further information.
Last year, the $29.4 billion Yale University endowment, New Haven, Conn., run by CIO David Swensen, who is known for his bold approach in alternative investing, allocated an undisclosed amount to two cryptocurrency funds, according to an October Bloomberg News report. Mr. Swensen did not respond for comment, and a spokesman for the school declined to confirm whether investments were made into cryptocurrency funds.

Red flags

Giorgio Carlino, a managing director and CIO of the global multiasset team at Allianz Global Investors, New York, said in a phone interview that there are “too many risks involved” in investing in cryptocurrencies to date, with the primary risk being valuation. “As an institutional investor, you should not, you could not actually, explain a position in bitcoin … or any other crypto in your portfolio as an asset allocation.”
“The valuation of the cryptocurrency is not possible as of today,” he said. “They have no income, there’s no intrinsic value, there’s no guarantee by a state or a central bank. It is an interesting concept and I’m fascinated, but it’s not an investment.” But Mr. Carlino does see a case for gaining an exposure to the cryptocurrency industry itself, by way of venture capital investments targeting firms banking on the future of blockchain or so called cryptoassets. But he describes even these investments as “high risk.”
“There are different ways of using cryptocurrencies that are, I see in the future, absolutely there. … J.P. Morgan has made a gigantic investment themselves,” he said.
Last month, J.P. Morgan Chase & Co., New York, became the first U.S. bank to create and successfully test a digital coin representing a fiat currency. “JPM Coin” is a prototype which the bank plans to use to enable payment transfers between institutional customers, such as banks and broker-dealers, using blockchain technology, the company said in a Feb. 14 announcement on its website.
The development comes despite J.P. Morgan Chase CEO Jamie Dimon’s noted skepticism of bitcoin, having called it a “fraud,” and going as far as to say he would fire any employee trading the cryptocurrency, Bloomberg News reported in September 2017.
Earlier this year, Andreas Utermann, AllianzGI CEO and global CIO, offered his own thoughts on cryptocurrency investing in a LinkedIn post, writing: “As an asset or a currency … the value of a cryptocurrency is in the eye of the beholder. This makes cryptocurrencies entirely unsuitable for investing in.”
While some in the industry have issued a strong word of caution on framing cryptocurrencies as a legitimate investment option, at least to date, investment consultantCambridge Associates LLC, Boston, has signaled that institutional investors should be exploring opportunities in the cryptocurrency and broader blockchain industry.

Consultant sees opportunity

Cambridge published a white paper Feb. 19 that explained various types of “cryptoasset investments,” including ways investment managers can gain exposure — from purchasing liquid cryptocurrencies, like bitcoin, to making investments in companies “whose returns are connected to the growth of the asset class,” as the “liquidity of these investments is similar to traditional venture capital investments,” the paper said.
“Although the crypto industry remains in its infancy, we think institutional investors should begin exploring it,” the paper noted.
Cambridge cautioned that an allocation to cryptoassets exceeding 1% of a portfolio on a look-through basis “does not appear prudent, even for those comfortable assuming the very high risks involved,” the paper said.
Marcos Veremis, a Cambridge managing director in Arlington, Va., and co-author of the paper, confirmed that many funds which primarily invest in cryptocurrency or blockchain companies also allow direct investment in cryptocurrencies.
“We see many funds build in the option to invest in cryptocurrencies, such as bitcoin,” he wrote in an email.
Cambridge said that, despite challenges such as very high risks in the space, “we believe that it is worthwhile for investors to begin exploring this area today with an eye toward the long term.”
Other consultants, including Aon Hewitt Investment Consulting Inc., CallanLLC andMercer Investment Consulting LLC, have not given institutional clients the go-ahead regarding such investments, though they continue to monitor the field.
“Cryptocurrencies are themselves in a bear market and it would be dangerous to extrapolate future results from a past record that has really shown the ups and downs of this (potential) asset class with bubble-like qualities,” said Zornitza Taleva, a senior hedge fund consultant at Aon Hewitt, New York. “We are skeptical of the role of crypto funds in a global institutional portfolio.”
Mark Wood, Callan vice president and U.S. equity investment consultant, said in an April 2018 research paper that the firm “does not recommend our clients invest in cryptocurrency strategies due to concerns over asset security, liquidity, unclear tax implications and heightened volatility.”

‘We remain cautious’

Mr. Wood said in a February email that Callan still holds this view, but that its stance was “targeted at a direct investment in crypto tokens (or funds that invest in a basket of tokens) — we remain cautious given the heightened volatility, liquidity concerns, high fees and evolving custodial infrastructure.”
Mercer also does not recommend investment in cryptocurrencies or, so-called “cryptoassets,” including venture capital funds that look only at that sector, said Matt Scott, a strategic research specialist based in Bristol, England.
Mercer’s main concerns are related to volatility, Mr. Scott said, but there are also other factors such as environmental, social and governance issues. Some cryptocurrencies have been used “primarily for illegal transactions, like purchasing narcotics or circumventing a country’s capital controls,” for example, he said.

Strategies for quantum races

Date: 2018-09-27
Author(s): Troy Lee, Maharshi Ray, Miklos Santha

Link to Paper

We initiate the study of quantum races, games where two or more quantum computers compete to solve a computational problem. While the problem of dueling algorithms has been studied for classical deterministic algorithms, the quantum case presents additional sources of uncertainty for the players. The foremost among these is that players do not know if they have solved the problem until they measure their quantum state. This question of `when to measure?' presents a very interesting strategic problem. We develop a game-theoretic model of a multiplayer quantum race, and find an approximate Nash equilibrium where all players play the same strategy. In the two-party case, we further show that this strategy is nearly optimal in terms of payoff among all symmetric Nash equilibria. A key role in our analysis of quantum races is played by a more tractable version of the game where there is no payout on a tie; for such races we completely characterize the Nash equilibria in the two-party case. One application of our results is to the stability of the Bitcoin protocol when mining is done by quantum computers. Bitcoin mining is a race to solve a computational search problem, with the winner gaining the right to create a new block. Our results inform the strategies that eventual quantum miners should use, and also indicate that the collision probability---the probability that two miners find a new block at the same time---would not be too high in the case of quantum miners. Such collisions are undesirable as they lead to forking of the Bitcoin blockchain.

OneLedger: Avance tecnológico para las empresas
Una combinación mortal. Tecnología revolucionaria combinada con bombo y frenesí. Este proyecto tomará cripto mundo por sorpresa. Muy raramente llega un ICO al mercado que hace reclamos jactanciosos, pero también muestra tecnología prometedora para respaldarlo.
Cómo elegir entre cientos de ICO que tienen lugar cada semana / mes? Cómo se preselecciona? ¿Cuál es su criterio de elección? Si invierte en un solo ICO en un año, y mucho menos en ICO del mes o ICO de la semana, le presento OneLedger, fácilmente el ICO del año. Una combinación mortal: tecnología revolucionaria combinada con exageración y frenesí. Este proyecto tomará cripto mundo por sorpresa. Muy raramente llega un ICO al mercado que hace reclamos jactanciosos, pero también muestra tecnología prometedora para respaldarlo.
Cuando salimos del mercado cripto bajista, no hay mejor momento para volver a invertir en criptografía ahora. No solo Bitcoin está mostrando sentimientos alcistas, las monedas alt también se están preparando para otro rally, a las nuevas alturas y nuevos máximos históricos. Lo que les propongo hoy no es solo el cripto comercio, sino la oportunidad de invertir en el siguiente gran pensamiento para entrar en el espacio criptográfico. Entonces, ¿qué tiene de especial OneLedger, podrías preguntar? Veamos lo que OneLedger en sus propias palabras:
OneLedger es un protocolo independiente de contabilidad cruzada que permite la escala de alto rendimiento utilizando un esquema de consenso tolerante a fallas bizantinas difuso y modificado, que permite una configuración sin permiso o permitida. Al acoplar la infraestructura de claves públicas (PKI) con la gestión de identidades, los nodos (y los operadores de nodos) tendrán una jerarquía de confianza definida que les permitirá participar en el consenso de la cadena OneLedger o de cualquier cadena lateral. Las cadenas laterales OneLedger se pueden sincronizar con el estado actual de otras redes (Ethereum, Bitcoin, etc.). Cualquier criptomoneda que admita contratos de bloqueo de tiempo hash (HTLC) y canales de pago podría depositarse en una cuenta o dirección con el importe abonado en la cadena lateral de OneLedger. Esto permite una solución escalable y transparente que está fuera de la red o cadena principal y ahora está descargada a la cadena lateral de OneLedger. Se puede producir un número arbitrario de transacciones entre usuarios en una cadena lateral de OneLedger antes de que el usuario final solicite un retiro de su saldo de la cuenta / dirección de bloqueo temporal en la cadena principal a la dirección / cuenta de su elección. Esencialmente, OneLedger proporciona una solución escalable fuera de cadena de cualquier cadena principal y descarga el consenso a la cadena lateral OneLedger correspondiente que hereda todas las propiedades del protocolo OneLedger. Al usar el control de roles con PKI, las empresas también pueden lanzar sus propias cadenas laterales autorizadas. Las empresas podrán definir la función precisa de los operadores de nodo que participan en su cadena lateral. Además, al utilizar el marco unificado de OneLedger, las empresas pueden desarrollar su aplicación de tecnología de contabilidad distribuida con una única base de código y simultáneamente lanzar su producto a través de las redes de infraestructura múltiples que elijan.
En pocas palabras, desde propietarios de pequeñas empresas hasta empresas, la misión de OneLedger es simplificar la adopción de las empresas de la tecnología blockchain y su integración en sus aplicaciones y productos comerciales específicos.
Habiendo explicado la tecnología, echemos un vistazo a Token Economics: Los tokens se usarán de varias maneras. Por ejemplo, los usuarios de la plataforma tendrán que pagar tokens OLT a los corredores de nodo en tarifas. Es posible que los propios corredores de nodos tengan que replantear tokens OLT en el futuro para garantizar la calidad de la red. Además, los desarrolladores recibirán pagos en tokens OLT por la creación de módulos, con transacciones ejecutadas en contratos inteligentes predefinidos que permiten compras de una sola vez, pagos de modelos de suscriptores, etc. Los tokens se valorarán en función del valor que tenga la comunidad ve en OneLedger. Si hay muchas empresas que demandan módulos especializados, muchos usuarios aprovechan sus servicios y se ejecutan muchos nodos para admitir la red, la demanda y el valor de los tokens OLT crecerá.

El equipo de OneLedger tiene 9 miembros del equipo enumerados, siendo el siguiente el núcleo:
David Cao, fundador y CEO: más de 16 años de experiencia en el comercio, con su experiencia más reciente como Xerox como Lead Commerce Consultant.
Alex Todd, CTA — Más de 30 años de experiencia acumulada en gobernanza corporativa general y tecnológica, con su experiencia más reciente siendo PRESTO como CTO.
Stephen Li, Ingeniero Líder — Más de 15 años de experiencia en desarrollo de software y consultoría, siendo su más reciente fundador de Services Informatiques YANG-LI INC.
Paul W. Homer, ingeniero principal de Blockchain: más de 30 años de experiencia acumulada en ingeniería y análisis de software, siendo su más reciente consultor de aplicaciones para CIBC.
El equipo también tiene un conjunto de asesores que incluyen a Trevor Koverko, CEO de Polymath, Matthew Niemberg, Consultor de Led Distributed, Craig G. Brown, Senior Canad.

Lets get straight to the point. I know XXXXXXXX one of your passphrase. There is no one who has compensated me to investigate you. You do not know me and you are probably wondering why you are getting this email? Amrit Steven Richard Beverly Gina Valerie Dailin Karysa Maria Voncille Let me tell you, I placed a malware on the adult video clips (sex sites) website and you know what, you visited this site to experience fun (you know what I mean). When you were watching video clips, your internet browser began working as a Remote Desktop that has a keylogger which provided me access to your display screen and also cam. Right after that, my software gathered your entire contacts from your Messenger, social networks, and e-mail . Next I created a double video. First part displays the video you were viewing (you've got a good taste rofl), and next part displays the view of your web camera, & it is you. Lashaundra Yjii Jorge Patrick Andrea William Taylor Kristen Kevin Angela You got two alternatives. Why dont we look at these possibilities in aspects: Leila Tommy Theodore Stacey Jeovanny Rodney Joe Sante Holly Ileiny 1st solution is to just ignore this e-mail. In such a case, I will send out your very own video clip to all of your personal contacts and thus visualize regarding the disgrace you experience. And likewise should you be in a loving relationship, precisely how it will eventually affect? Carter Kenneth Joanna Victoria Deon Ben Allegra Thomas Keith Bre Next solution should be to compensate me $2000. We are going to name it as a donation. In this scenario, I most certainly will asap eliminate your video recording. You can keep going on everyday life like this never took place and you would never hear back again from me. Tracy Cathryn Maria Jacob Jennifer Gerard Pamela Patricia Esther Richard You'll make the payment by Bitcoin (if you do not know this, search for "how to buy bitcoin" in Google).

I have dealt with my actions. I am also not attempting to ask you for money a whole lot, I simply prefer to be paid for. I've a unique pixel within this email message, and at this moment I know that you have read this email. You have one day in order to make the payment. If I don't get the BitCoins, I definitely will send out your video recording to all of your contacts including family members, co-workers, and so on. Nonetheless, if I receive the payment, I will erase the video right away. If you really want evidence, reply with Yea & I definitely will send out your video recording to your 9 friends. It is a non:negotiable offer and thus do not waste mine time & yours by responding to this e mail.

Bitcoin dev IRC meeting in layman's terms (2016-01-07)

Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms. Link to last summarisation
Please bear in mind I'm not a developer so some things might be incorrect or plain wrong. There are no decisions being made in these meetings, but since a fair amount of devs are present it's a good representation. Copyright: Public domain
link to this week logs Meeting minutes by meetbot
Main topics discussed where:
0.12 Release candidate Detailed roadmap for next projects
Short topics/notes
Gmaxwell has asked Luke-Jr to take over as BIP-editor. He'll be working on clearing up the back-log. He mailed the mailinglist for information.
All platforms seem to compile bitcoin with C++11 now. Travis still needs a C++11 compiler, which cfields will enable.
Segnet will do a backwards incompatible change soon, to change the commitment structure.
0.12 Release candidate
Bitcoin Core 0.12 is scheduled for release around February and introduces a lot of fixes and improvements.
It still needs some more info in the release notes. PR's #7151 and #7149 are mentioned to possibly still be included in 0.12 as well as a quick fix for #7098 (to be written). Morcos feels strongly that releasing 0.12 as is, is pretty bad. Due to the smartfee changes stuck transactions should be really rare, but if they happen it's worse than 0.11, as the network more easily "forgets" transactions. PR #7312 "Add RPC call abandontransaction" is proposed by Morcos to be a quick-fix to enable users to make their wallet forget about the inputs to a transaction that's not in the mempool. Better solutions should be build for 0.12.1
Take a look at PR's #7151, #7149 and #7312 Cfields will work on a fix for #7098
Detailed roadmap for next projects
Morcos makes a request for some direction on what sort of timeline projects are on, and what the order of implementation should roughly be. This so there's a concentration of effort and focus. A more clear plan could result in investing resources into the right parts.
Jonasschnelli will work on RBF features for the wallet. Cfields is planning to post a request for comments for a network stack overhaul next week. BIP 9 versionbits is moved back in priority a bit. Libconsensus refactoring needs a scheduled time to do, as well as C++11. Clang format might not be worth it, if so we need to communicate that it won't happen.
Everyone that is working on something that they plan to have finished for 0.13 should send wumpus his proposals, so he can merge it into a plan.
