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, introduction, 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 (transaction). 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. decredinfo.com: 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 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).
Update 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 – translated, 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.
Changenow announced the option to buy DCR with fiat.
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. Arbitrade is now mining Decred.
Campus Party in Brasilia, Brazil. @girino, @Rhama and @matheusd talked about Decred. Matheus was interviewed by a TV channel. Check this quick report about the event, click "Show newer" to continue reading. (photos: 123)
Blockchain Summit in London, UK. This was not a full blown presence with stand but rather investigation of opportunities by @kyle and @Ani. The resulting detailed report is a good example of a document advising to stakeholders whether it is worth spending project funds.
Meetup in Berlin, Germany on July 18. @jz will give a talk and Q&A about Decred and chat with Ele from @oscoin about incentivizing developers. Hosted by BlueYard Capital.
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)
Decred Assembly - Ep20 - Governance: Driving the Future (youtube) @cburniske and @traceagain discuss the importance of governance protocols being foundational and problems with delegated proof of stake
"I think that developers in the future are going to base their decision on where to build on the basis of governance and community. And so I look for good governance mechanisms and strong communities in blockchains." (@decredproject)
What is on-chain cryptocurrency governance? Is it plutocratic? by Richard Red (medium)
Apples to apples, Decred is 20x more expensive to attack than Bitcoin by Zubair Zia (medium)
What makes Decred different and better from other cryptocurrencies? (cxihub.com)
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 nowviewable 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, #random, #trading 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)
A chat 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 and #governance. "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; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms. 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.
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?

Substratum leads Round 2 of Monthly Community Voting Round - AMA Transcript Inside!
Hey guys, If you haven’t noticed on Binance’s monthly community voting round – it has been a tight battle but Substratum has been taking the lead. I wanted to explain why Substratum has seemingly come out of no-where but has garnered some attention. Substratum is creating a solution to a very big obstacle in the world web. The below has been taken from Justin Tabb aka the Founder of Substratum and summarises what the purpose of the network is. I hope you guys can support their vision by voting for Substratum (SUB) on the https://www.binance.com/vote.html. The Substratum Network will bring the decentralized web worldwide without the need of special software for the average internet user. We will be able to serve Substratum Requests directly to the default browser (Safari, Firefox, Chrome, Internet Explorer) without any special software installed on the average consuming users computer. How Substratum Works Ease of Use: currently nearly everything that has to do with crypto or the blockchain is very difficult to use and requires technical knowledge. Through our 10+ years of experience working with companies like Apple we understand the importance of a good user experience. • The average internet user requires NO special software to use the Substratum Network. The default browser will service all requests for average users so they do not need to do ANYTHING different. Users who wish to service requests and receive SUB coins in return will have a point and click user interface that any user can setup. No technical knowledge required. SubstratumPay will be seamlessly integrated and geared towards high conversions of low technical expertise users. • Serving Up of Decentralized Content: Substratum provides a method for serving Decentralized Content (including Web Sites, Data, and Applications) through a Mac, Windows, and Linux application/service that is easy to install and run (requires no technical expertise) and serves up decentralized content using the toolkit that we have developed. This is a point and click process and requires zero technical knowledge. All the user has to do is install the application, click through a few settings and they are up and running and making Substratum Coin. Incentivizing Users to Serve the Content: in order to incentivize users to run the Substratum Network client on their machine we will be providing Substratum Coin to them for doing so. The coin is issued to the serving machine through a micro-transaction from the hosting site to the serving computer. By breaking fees down to a micro-transaction level this will greatly reduce the overall cost to companies and entities that want to host sites and applications on the internet solving yet another problem with the web as it stands today. Privacy / Security / Encryption: by allowing millions of Substratum Network users to serve content the biggest concern becomes privacy and security. Substratum solves these issues through advanced cryptography algorithms rooted in Artificial Intelligence that ensures all data remains secure. Following the lead of BitCoin this is the strength of cryptocurrency and the crypto movement. Storage and Serving of Content: in order to serve millions of sites, databases, and applications the Substratum Network employs custom developed advanced compression algorithms and machine learning to geolocate the right Substratum Network machine to serve up the content to the appropriate user based on geolocation, this will ensure the fastest load time with the lowest amount of latency and strain on the Substratum Network and both the serving and receiving machine. DNS (Domain Name System): DNS or the Domain Name System is the system that currently tells your browser where to go when you type in a domain name. For instance when you go to Chrome and type in apple.com a DNS lookup is performed to check where to send that request, the DNS system comes back with an IP address and your request is routed there. In the first version of SubstratumDNS will be a complex, AI enabled DNS server that will receive DNS requests along with the geolocation of the requestor and find based off of that information the closest available SubstratumNode that is able to fulfill the request. Development Tools for the Decentralized Web: the Substratum Network will provide an API and SDK for developing tools on the Substratum Platform. This will bring in strong developer support and will accelerate the growth of the decentralized web on the Substratum Network. Net Neutrality: with the Substratum Network ALL web-sites and applications will have EQUAL ability to be broadcast in an equal and fair manner. International Digital Barriers: currently countries like China have strict regulations on what their 1.379 billion citizens are able to interact with on the internet. Substratum will break down these barriers through a network of decentralized computers running the Substratum Network Software. Where other solutions that are currently used by residents in these countries require special software to be installed, like TOR, Substratum will take a reverse approach and require no special software for the average user. High Hosting Costs: currently businesses must pay high hosting fees to get their web-sites on the internet. Amazon Web Services launched a 3.5BIL USD per year business by attempting to solve this problem. They allow you to pay for how many minutes you run a web / database server. Substratum completely solves this problem through the power of cryptocurrency by only charging for each request that is processed. You can check out the website here: • Substratum.net o And the whitepaper is available in multiple languages inclusive of Mandarin. Furthermore, Substratum and the founders are very active in the slack – which they have recently hosted an AMA (ask me anything); I took the liberty of getting this information and if you are interested about the project to read more into it. Obviously they can’t reveal the inner workings of their product due to product sensitivity and being ahead of their competition but they are always up to date with the community through several videos on Youtube (https://www.youtube.com/channel/UCxUJoTH0XLERKl55zGnFI6g) and announcements through their social media. I recommend you follow them. Q: Any major talks with exchanges yet? A: We just announced that we are launching on our FIRST official exchange of COSS.IO on 9/30 trading against BTC and ETH. More to follow. Q: Will I be able to run a supernode? A: From the beginning NO. Supernodes will only be for Substratum; however, they will run the SAME software that are used to run a NODE. In time we will develop a requirement list to run a supernode. If you qualify you can then run a SuperNode and receive a premium payout Q: Is it possible to show a few examples of SUB payouts you get from running a node, and the tell us the ratios that affect the amount/way to calculate it somehow? (SUB owned, for how long you've been running a node etc..) Or is that still in testing? What's the difference in node rewards from someone who has 0 SUB's as opposed to someone who has X amount of SUB's? A: So the calculations for this are in process; however, you can watch our video "How Substrate Per Request Is Calculated" on our YouTube channel for an idea of what variables go into each calculation Q: How do we prevent DDoS? A: The first step is not talking about how we prevent DDoS or any other hack. We call that security through obscurity. :slightly_smiling_face: Secondly, one of the primary ways to prevent a DDoS attack is decentralization. Well that's perfect. Lastly, there are other techniques, like black-holing and basically shutting a node down. The great news is that we will be decentralized so we are only talking about a node or specific IP Address that will not disrupt the network. :thumbsup: Q: Say i got a website i want to publish on Substratum, how does this process go? A: Just a shout out if you ask for a lot of detail regarding technology stack and how exactly something will work we are most likely going to give you general answers. This is not to skirt the question. We want to be 10 steps ahead of anyone with nefarious plans before we get launched. You will be seeing more on this very soon. You should be seeing a video drop on this in the next week or two. The goal is to make this easy to use and powerful, plus empower others to use the tools. We're looking at things to different ways one is towards the average user who just want something sitting on their system and doesn't need any more details and the other is a super user who wants a lot of configuration options. Q: When more people will use Substratum and more will run nodes, the value of SUB will increase. How will it be calculated how much SUB you get as a reward for running a node as value increases? Will it be calculated by Substratum itself or will it be changed manually every so often? A: We will be calculating against the live value of Substratum Q: Is substratum detectable, for example if it’s used in a country like china and they are caught on these sites that are blocked by government… Can it be detected? A: The goal is to make it constantly moving. We do not want it to be. fast, easy, powerful, anonymous. Q: Will there be Master Nodes? A: We will have some services that are available that will help provision nodes into the network. We are still story mapping this flow and architecture. Q: Could we get more information about what you require to do to be a beta tester? A: To be a beta tester you only need to add yourself to the #beta-tester channel here in Slack. You will be notified when we are ready for you to download and install and the process and requirements to continue to run the software Q: Will you keep us informed on a at least weekly base to tell/ show us the progress made? A: Yes! We will continue to drop at least 2 professionally made update videos each week (with Jason Burns the guy who does them) and we will be doing more and more candid videos Q: Who is the winner of 10k subs and what idea did he give? And what about 2nd place and 3rd place. A: To be announced shortly. The Substrate is reserved for the payout Q: Can we mine Sub without the software? A: I will personally be selling pick-axes on my personal website "pixaxesforsale.biz" for a low cost of $19.99 Q: Unless they disclose intelligent life in space, people are still going to be mad at the end of this. A lot more will be happy though A: Haven't found intelligent life in space. Some would question finding it on earth. Q: From a legal stand point How are we protected if someone is running illegal content on our Node? A: Take a look at our video of "How Substratum Secures Your Site Content". You will never hold the entire piece of data except perhaps in memory if you are the one serving the request so you could never be culpable. Amazon isn't held responsible if I host illegal content now Q: What about content control? child porno .. and so on ... ? Is there anything to control the content or? A: Excellent question. This was a big concern for us. We do not want Substratum to become the dark web. The goal is to allow the community to self-govern, vote up and down, call out illegal activity. The utilities will allow those with bad intentions to be called out. The more we grow the better we will be about wiping out things like child porn, and just as bad human trafficking. Q: When will the raised money going to be donated? A: We have already donated $10K out and we have a pending wire for $40K going out Monday. We are working to find the BEST places with the IMMEDIATE needs. Q: When will the livestream of the burn be? A: Burn #1 will be a livestream of my computer screen later tonight. I will announce on twitter at least an hour ahead of time and we will record it so people can see it later Q: What will the final circulating supply be after all three token burns? A: We are still getting a FINAL number on this, we are still doing some FINAL Bonus sends but we will have the number VERY VERY soon and we will be posting it. We will be burning 60MIL tokens tonight so that should give you some kind of an idea. Q: can you stop slack from freezing my firefox? A: Use the downloadable app, or get better internet, or get a new computer. Sounds like a dumpster fire. Q: Everyone brings up the obvious choice of child porno that needs to be dealt with via content control. What about grayzones such as weed-selling sites? Its illegal in some countries, some not. How will Substratum deal with these grey-zones? A: Give me liberty or give me death. Q: Could i have an invite to beta test channel on slack? A: Yes, just let a moderator know. Q: could i get more information on what beta testers are required to do? I will happily be one if it helps the process and I actually manage to do it. A: Join the #beta-testers channel here Q: when will we see a new homepage? A: This is being worked on now! Q: is there a minimum amount of SUB needed to run a node? A: NO! 0 Substrate, don't worry, you will have some soon once you turn it on Q: What about running an "micronode" on any phone (there is a big % using phones all the time), I mean an app installed on phone to run a node and to host only small content like a photos... Did you think about of this? A: https://youtu.be/h6tZ_ZFuFmY Q: What if my website ethically and morally right and people downvote it out of jealousy will my website be removed if there are more number of downvotes and my content is clean? A: The process is NOT that simple, we will release more details later but this is being taken into consideration. I answered in a bit more detail above as well Q: Does the Sub team ever sleep ? A: Only when driving Q: Can I run a node on a VPS? A: I certainly won't be telling people how or where to run the node software. Do the best you can. I actually answered the VPS question above too. We will have a command line version if that is the question. That you can run on something like Ubuntu Server if you want Q: Can the voting system for all illegal stuff on the internet also be used in a 'bad' way on the regular websites to for example gain commercial/business advantages? A: It should not, no one will have 'master control' All control, so the market decides always. Q: Who will profit from cryptopay? How will this bring value to SUB tokens? A: Everyone will as we gain dominance. But also, Substratum the company will take a small percentage. This will enable us to continue building awesome apps. CryptoPay will be the cornerstone of many good things to come. Think retail, goods and services. Q: I work at a games company with 200+ high powered pcs. If I install sub nodes on every single one of them at night, will IT be able to catch and fire me A: See your HR manual, or HR supervisor for those questions. Q: How do websites and hosters remain protected from hacking, if sites are created with innate vulnerabilities does that expose other sites hosted by the same node? A: This is a great question. Hosting Nodes will have to vet out their security. Again, being decentralized goes a long way in providing security. So does encryption. We will help hosts be the best hosts possible. Q: Please explain the earning in SUB by running a node? A: So the SUB comes FROM the HOST (who purchases the SUB) to the NODE for the cost of the transaction. https://youtu.be/LWZ1DIGGOoQ Q: When will the tokens be sent for the 100 Sub giveaway A: Shortly Q: How will Substratum market themselves towards countries that needs SUB the most but are hard to reach, such as North Korea, Africa, China? A: Think spider web. The more that join, and use, the less it can be controlled. Q: How long will this bear market last for? A: Let me put the fortune teller hat on. Crypto is a young demographic currently. It will be bear'ish until we make the technology easier and they get older.
