May was quite an epic month for Decred:
DCP-0007 - the algorithm that determines the maximum monthly spend from the new treasury was fixed, and should no longer interfere with making monthly payments to contractors.
DCP-0008 - nodes now reject newer transaction versions they can’t handle, and explicit consensus upgrades are now required to define and allow newer versions. It will be easier and less error-prone for all actors in the Decred ecosystem to integrate with future consensus changes. Some engineers would even say that fully-validating nodes rejecting data they cannot fully validate is the only sensible way to operate. With this upgrade, Decred doubles down on hard forks as the most secure and reliable way to upgrade consensus, “because we can”.
DCP-0009 - miners now revoke missed and expired tickets automatically. This removes a big user frustration of dealing with revocations, and especially the pain of lost (not backed up) redeem scripts. Wallet code and GUIs become simpler, staking becomes easier.
DCP-0010 - 50% of each block’s reward is redirected from PoW miners to PoS voters, changing the split from 60/30/10 to 10/80/10 for PoW/PoS/treasury. This will hopefully rebalance the supply and demand of DCR and reduce the ability of malicious actors to manipulate the markets. As a byproduct, higher PoS rewards make it more attractive to stake DCR. This was the most debated proposal so far, but stakeholders said Yes and after around 6 months it is live.
This is perhaps the biggest consensus upgrade in Decred’s history.
dcrd and dcrwallet v1.7.2 were released on May 11 - the latest version as of writing. dcrd got a fix for a rare and hard to hit case when optional indexing is enabled. dcrwallet received a fix for
verifymessage, enabled change of public wallet passphrase, and some internal/developer changes. Release notes.
Decrediton v1.7.2 added support for voting on treasury spends, more information in VSP staking, updated DEX module, and several bug fixes. v1.7.3 has followed on May 18 with fixes for macOS 10.15 and setting treasury spending vote choices. Release notes.

Android and iOS wallets v1.7.0 were released on May 11.
Changes since v1.6.1 include:
The work reported below has the “merged to master” status unless noted otherwise. It means that the work is completed, reviewed, and integrated into the source code that advanced users can build and run, but is not yet available in release binaries for regular users.
dcrd is a full node implementation that powers Decred’s peer-to-peer network around the world.
The general direction in May was to further leverage the consensus changes that activated recently, by adding optimizations and removing unneeded code.
mainnetand can not be exploited since the automatic revocations agenda has activated.
assumevalidblock (hard-coded in each release). Semantics have been clarified to reflect that “checkpoints” are now only used for handling old forks and are no longer used for optimizations (that now rely on other methods). The
--nocheckpointsCLI option has been replaced with
--allowoldforks. With this change, the role of checkpoints is reduced to a minimum, which is desirable since they are a kind of a workaround.
searchrawtransactionsJSON-RPC. Address index was a lot of overhead from a development perspective to maintain, it wasn’t used by anything of note, and it didn’t really easily provide what most people want from addresses anyway, which is a full balance as opposed to all of the individual transactions. All of the information it provided, and more, is available via dcrdata.
blockchain/standalonemodule, which is nice for consumers (e.g. DCRDEX) since this module has very few dependencies.
blockchainpackage internal and not exported. This is part of a continuing overall effort to reduce the total number of exported packages and modules to reduce the maintenance burden, and eventually get to the point it will be possible to follow semantic versioning for the root module.
Released with the v1.7.2 patch:
walletpubpassphrasechangeto JSON-RPC methods. It allows to change wallet’s public passphrase.
getstakeinfocommand (caused by changes regarding expired tickets).
Decrediton is a full-featured desktop wallet app with integrated voting, StakeShuffle mixing, Lightning Network, DEX trading, and more. It runs with or without a full blockchain (SPV mode).
Merged and released with May’s v1.7.2 and v1.7.3 patches:

Changes in the pi-ui library (common UI elements for Politeia and Decrediton):
vspd is server software for running a Voting Service Provider. A VSP votes on behalf of its users 24/7 and cannot steal funds.
dcrlnlpd stands for “DCR LN Liquidity Provider Daemon”.
Meet the the newest project in Decred’s LN ecosystem:
This service allows running a Lightning Network Liquidity Provider in the Decred network.
This LP allows remote clients to request the node associated to the LP to open an LN channel back to the requesting client. This allows the requesting client to have some inbound bandwidth to receive LN payments.
To create the channel, the LP charges some amount, specified as a percentage of the desired channel size. [README file]
DCRDEX is a non-custodial exchange for trustless trading, powered by atomic swaps.
Internal and developer changes:
Dev team has started a discussion on renaming DCRDEX and are accepting name and logo ideas.
Probably found a vendor to perform an audit of our Solidity atomic swap contracts. Notably, our contracts are so simple, we’re under their minimum order size. That’s what happens when you’re not trying to extract trading fees and there’s no admin functionality. [@blockchainbuck]

GoDCR is a lightweight desktop GUI wallet with integrated staking, privacy, Politeia voting, consensus voting, and more.
Android and iOS builds of GoDCR already function in some capacity, although there remains a lot of work to polish the mobile/touch UX.

Community stats as of Jun 1 (compared to May 2):
See June 2022 report on Decred SM performance for a more in-depth look at Feb vs Jun numbers.
In May the new treasury received 9,407 DCR worth $390K at this month’s average rate of $41.46. 2,950 DCR was spent from the legacy treasury to pay contractors, worth $122K at May’s rate, or $179K at April’s billing rate of $60.62. These payments were to cover both March and April’s contractor invoices.
A new proposal was submitted by Raedah Group to fund GoDCR, the desktop GUI wallet built in pure Go which will also replace existing mobile wallets as development continues. This proposal requests $250K for 12 months of funding, a greater amount than the previous proposal which was narrowly rejected in October 2021. The extra budget is due to larger number of workers, a longer duration and covering the maintenance of existing Android/iOS wallets. The budget was reduced from the initial $300K in response to some comments.
Four proposals were published on Politeia in May:
The proposal from @Exitus to fund Decred Journal and Politeia Digest until December 2022. DJ was inactive for 3 months since @bee announced the halt, until @Exitus took over the lead of the April issue and eventually a full new proposal. A detailed report on the 2021 proposal’s deliverables and finances was published here, with key stats being $24,800 spent out of $39,000 to release 12 issues of DJ and 10 issues of PD. The new budget is capped at $33,000.
The proposal from @kozel to fund Decred content and asset translations throughout 2022. A report on Phase 2 informed that only $8,180 out of $33,000 was spent, so Phase 3 will have a lower limit of $20,000.
The proposal to fund continuation of the Bug Bounty program until December 2023. For the last 12 months the operating costs were ~$2,100 and ~$1,000 were paid as bounty rewards. The new proposal has duration increased from 12 to 18 months, the budget is split between $5,000 for operating costs and up to $100,000 for reward payments. The leadership was transferred from @degeri to @jholdstock.
The proposal from @juliana requested $3,575 to run 3 events at universities in Uganda in 2022, with 30 people expected at each event.
See Politeia Digest issue 51 to catch up on proposal activity between January and May.
Hashrate: May’s hashrate opened at ~345 Ph/s and closed ~115 Ph/s, bottoming at 74 Ph/s and peaking at 381 Ph/s throughout the month.
Image: Anticipated hashrate drop after the mining reward reduction.
Distribution of hashrate reported by the pools on Jun 1: Poolin 55%, ViaBTC 21%, F2Pool 7%, AntPool 7%, Luxor 5%, BTC.com 4%, CoinMine 0.3%.
Distribution of 1,000 blocks actually mined before Jun 1: Poolin 55%, ViaBTC 20%, F2Pool 8%, DsV1GF7 6.5%, BTC.com 6%, Luxor 4%, CoinMin2 0.2%, DsmLNFC 0.1%.
All missed and expired tickets have been revoked, unlocking a total 175,957 DCR from 1,719 tickets (average price 103 DCR per ticket). ~45K of that DCR have moved already, while the remaining ~131K DCR are likely lost due to lost seeds and other reasons. One of the revoked tickets was from an old block 767, around the time when first complaints about the high ticket price appeared.
All new missed votes are revoked automatically, the first one revoked in block 657295.
VSP: On Jun 1, ~6,900 (+120) live tickets were managed by 16 listed vspd servers, or 16.8% of the ticket pool (+0.2%).
Legacy (dcrstakepool) tickets can no longer be voted since May 8 when the chain forked to the new rules. Unlike all other shutdown/stalled legacy VSPs, on Jun 1 coinmine.pl and decredbrasil.com reported that they’re on a current block height and collectively hold 19 live tickets. We are not sure how this is possible and these tickets are not included in the above stats.
Nodes: Throughout May there were around ~185 reachable nodes according to PD Analytics.
Node versions as of Jun 1 snapshot (160 total, dcrd only): v1.7.1 - 41%, v1.7.2 - 20%, v1.7.0 - 12%, v1.7.0 dev builds - 9%, v1.8.0 dev builds - 4%, v1.6.x - 6%, v1.5.x - 4%.

Decred Magazine has been launched by @phoenixgreen to collect all Decred content in one place, give new writers a platform, and archive great past content (Decred Journal included). The latter is valuable since websites and blogs commonly “evaporate” their content over time and it becomes hard or impossible to recover. As of writing, around 300 posts have been imported and 8 authors have explicitly agreed to add their content. Decred Magazine is intended as a replacement for decredsociety.com launched earlier as a pilot project.

Weekly Contribution Streaks is a new weekly activity from u/ersfbddfgwe that seeks to break the common mental barrier “I can’t contribute anything because I’m not a developer :(“. The “rules” are simple: just show up and write about anything you did, big or small, with an optional DCR address for tips. There is an ongoing discussion about how to better rank and reward contributions.
In Decred Mining Thread miners have been sharing the challenges of mining DCR after their block reward share was reduced from 60% to 10%.

In May DCR was trading between USD 30.00-58.68 / BTC 0.00103-0.00190. The average daily rate was $41.46.
@Applesaucesome is posting technical analysis of DCR, crypto, and the broader market on the new Decred Magazine website, about once a week.
In May, DCRDEX has facilitated the trading of ~74K DCR, equivalent of ~3M USD.
Insider trading in the crypto space is increasingly in the spotlight. The Wall Street Journal featured an article about suspected insider trading around exchange listings on Binance, Coinbase and FTX. The analysis was conducted by Argus Inc based on public blockchain records.
The former OpenSea product manager Nathaniel Chastain, who lost their job over profiting from the listing of NFTs on the OpenSea front page in September, has now been arrested and charged with insider trading by prosecutors in New York’s Southern District. Although the NFTs in question are not the usual securities which insider trading laws apply to, the DA is alleging that Chastain injured his employer (OpenSea) by misappropriating information.
Actor Seth Green lost his Bored Ape NFT in a phishing incident, made even more consequential by the fact that the ape had been set to star in a new show he was developing, White Horse Tavern. In June Green paid a $260,000 ransom to secure the return of the ape, so that the show could go on (without raising a lot of copyright questions over whether the stolen ape’s image could be used).
