Decred Journal - August 2018


dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.

The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCR/kB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.

Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.

The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.

The testnet was reset and bumped to version 3.

Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.

@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.

dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.

Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.

Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.

@degeri joined to perform security testing of Politeia and found several issues.

dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.

The upcoming v3.0 entered beta and is deployed on Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on

Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.

iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.

Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.

docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.

@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals. 8 contributors added and 4 removed, including 2 advisors (discussion here). is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.

Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)


Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by at 5% and Luxor at 3%.

Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.

Nodes: there are 217 public listening and 281 normal nodes per Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.


Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.

Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.

FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.

Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations joined the list of stakepools for a total of 16.

Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.

Three new OTC desks were added to exchanges page at

Two mobile wallets integrated Decred:

  • Coinomi added Decred to their Android and iOS wallets. In addition to the Apple App Store and Google Play you can download the APK directly. Coinomi features an integrated cryptocurrency exchange and is the first company to offer a mobile Decred wallet.
  • BitBill Android and iOS wallet also added Decred.

Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?



  • Bit Dials announced DCR support via GloBee at their luxury boutique. Their separate supercar and classic car shop also accepts DCR, either via GloBee or with manual invoicing in case of privacy concerns.
  • Sheldon Store re-enabled DCR payments. The shop sells gift cards for Amazon, iTunes, Netflix and many more.


Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.

Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Comm systems news:

  • Interruptions in the chat bridge led to some Slack messages not reaching other platforms, and consequently not being archived in Matrix.
  • Several impersonators were detected and banned.
  • Inactive Slack channels were archived. If you miss them, let it be known.
  • Mastodon was mentioned by several people as a possible alternative for Twitter.
  • Two new Reddit rules were added to prevent CAPS flood and duplicate submissions.

After another debate about chat systems more people began testing and using Matrix, leading to some gardening on that platform:

  • Decred Matrix community was created:, it helps to see all Decred-related rooms and people.
  • #privacy and #design are now bridged.
  • One private work channel was successfully migrated to Matrix.
  • Stylish room avatars were set.
  • @Haon has prepared a short guide to help new Matrix users get started and join the Decred rooms.


  • A thread was started to discuss changes to Decred jargon with the intent to make it more consistent and accessible to newcomers. The question whether changing "official" terminology requires stakeholder approval was touched in this thread and in #documentation.
  • Project fund transparency and constitution were extensively discussed on Reddit and in #general.
  • Pre-proposal to use Politeia to approve Politeia as a legitimate decision-making tool for Decred.

Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1.

Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment.

An unusual event was the chat about double negatives and other oddities in languages in #trading.


DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.

@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.

The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.

Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)

Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).

Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.

Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.

Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.

Finally, unrelated to Decred but good for a laugh:
