The biggest announcement of the month was the new kind of decentralized exchange proposed
by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response.
dcrd: Peer management and connectivity improvements. Some work for improved sighash algo
. A new optimization
that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue
for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage.
Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun.
Politeia is live on testnet! Useful links: announcement
, command line voting example
, example proposal
with some votes, mini-guide
how to compose a proposal.
Trezor: Decred appeared in the firmware update
and on Trezor website
, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue
dcrdata: Continued work on Insight API support, see this meta issue
for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged
and bumped version to 3.0. Work to visualize agenda voting continues
Ticket splitting: 11-way ticket split from last month has voted
Ethereum support in atomicswap is progressing
and welcomes more eyeballs.
decred.org: revamped Press page
with dozens of added articles, and a shiny new Roadmap page
: a new Decred dashboard by lte13. Reddit announcement here
Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart
Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s.
F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement
that they will consider measures like rising the fees to prevent growing to 51%.
Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak).
Nodes: there are 240 public listening and 115 normal nodes per dcred.eu
. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed
690 reachable nodes on Jul 1.
Extraordinary event: 247361
were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).
from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target.
Another Chinese ASIC spotted
on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.com
, also on asicminervalue
dcrASIC team posted
a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.
is a new mining pool spotted
- Huobi Pro added DCBTC and DCETH pairs.
- OKEx gradually rolled out trading DCR to BTC, ETH, USDT and OKB and added a page for Decred (note a bunch of N/As for ICO-related stats).
- Singapore-based DragonEx announced a DCETH pair.
- Netherlands-based Bitvavo recently added EUR to DCR conversion
- OOOBTC announced DCUSDT pair.
- Changenow announced the option to buy DCR with fiat.
Two OTC trading desks are now shown on decred.org exchanges
payment gateway added Decred and posted
Guarda Wallet integrated Decred. Currently only in their web wallet, but more may come in future. Notable feature is "DCR purchase with a bank card". See more details in their post
or ask their representative on Reddit
. Important: do your best to understand the security model before using any wallet software.
- NeverFiat marketplace now accepts Decred. Notably it utilizes GloBee and recently announced Lightning support for Bitcoin.
- Crypto and Tech Gear integrated Decred and has a branded mouse pad for sale, as well as other merch.
- TokenPride: "We are seeking feedback on the general setup of our payment processor. We have tried to make it simple and user friendly. 10% of all purchases made in Decred will be donated to the Decred Development fund - and we will be releasing original Decred designs in the future".
BlueYard Capital announced
investment in Decred and the intent to be long term supporters
and to actively participate in the network's governance. In an overview post
they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project).
The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below.

: a new website by @mm:
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack) @morphymore
translated Placeholder's Decred Investment Thesis
and Richard Red's write-up on Politeia
to Chinese, while @DZ translated Decred Roadmap 2018 to Italian
, and A New Kind of DEX to Italian
Second iteration of Chinese ratings released
. Compared to the first issue
, Decred dropped from 26 to 29 while Bitcoin fell from 13 to 17. We (the authors) restrain ourselves commenting on this one.
Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository.
An update on our communication systems:
- Matrix chat logs are now viewable on the web with the exception of some channels that are not bridged. The new web logs means our chats are now fully public and indexed by search engines.
- Slack had an outage on Jun 27 that disturbed communications for a few hours, discussions continued on Decred's bridged platforms.
Jake Yocom-Piatt did an AMA on CryptoTechnology
, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS. A new kind of DEX
was the subject of an extensive discussion in #general
channels as well as Reddit
. New channel #thedex
was created and attracted more than 100 people.
A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
about Decred fork resistance started on Twitter and continued in #trading
. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred.
"Against community governance" article
was discussed on Reddit
"The Downside of Democracy (and What it Means for Blockchain Governance)" was another article
arguing against on-chain governance, discussed here
Reddit recap: mining rig shops discussion

Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion
; possible hashrate
of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable
to SPV leaf/node attack.
DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market.
In the middle of the month Decred was noticed
to be #1 in onchainfx
"% down from ATH" chart and on this
chart by @CoinzTrader. Towards the end of the month it dropped to #3.
Launchpad service. The idea
is to work with coin developers to design a custom, ASIC-friendly PoW algorithm together with a first batch of ASICs and distribute them among the community.
Equihash-based ZenCash was hit
by a double spend attack that led to a loss of $450,000 by the exchange which was targeted.
Almost one year after collecting funds, Tezos announced
A hacker broke into
Syscoin's GitHub account and implanted malware stealing passwords and private keys into Windows binaries. This is a painful reminder for everybody to verify binaries
new asset listing framework for Poloniex. Relevant to recent discussions of exchange listing bribery:
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked
with a $30 m loss.
Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight
from Keynote Panel on governance: "There is no such thing as on-chain governance".
Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code
, just in case.
Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too?
