    DCR 科普内容其实在 https://docs.decred.org/ 都有很完整的记载。同时在社区讨论时 Matrix 里面也有专门的 Writers room 关于内容各方面的讨论。和Ditto的配合当中也包括了发展特定课题内容,让其中一些承包商成为某些课题的思想领袖。比如Medium 中或是最近 Ditto 推行发布在各大媒体的文章都是发展 DCR 为社区治理领先的角度推广,让更多有兴趣的人来了解的。

    当然这些活动暂时在国内还是欠缺,也有很大的改进空间。目前社区也有努力翻译内容和整理内容的工作在进行中。如果您或是社区有人愿意协助也欢迎加入我们。

    1. 目前staking看似大势所趋,DCR项目发布时间早,技术方面也受到国内很多开发者的认同,但是社区运营方面似乎欠了点火候,接下来是否有运营推广的新计划?

    2. 虽然Staking如火如荼,但如cosmos社区近期也在讨论销毁的价值是否大于增发,DCR团队怎么看这个问题?是否会坚持最初的路线走下去呢?

    DecredProject 版主 回复Keikei 发表于2019-04-29 16:06:54
    1. Currently staking seems like the trend. DCR project started early and technicality of DCR is recognized by many devs in CN but community operations are lacking. Is there any new plans on marketing ?


    2. Although staking are hot topic now, but in projects like cosmos community, there are also discussion on "is burning of coins more valuable than issueing more coins", how does DCR team see this? will it follow the initial plan?
    DecredGuang 版主 回复Keikei 发表于2019-04-29 17:36:11 嘉宾
    社区运营(特别是国内社区)方面确实欠缺了一点,由于DCR 的去中心化社区模式,推广计划都是社区自发,欢迎有意见或愿意贡献的社区成员一起参与讨论并发起提案。

    DCR 的 staking 与一般纯PoS staking 模式有点不一样。传统PoS是通过增发来发放PoS奖励,而 DCR 实际是个 PoW 币种,增加了 PoS 层面验证作为治理。DCR 的总量和比特币一样 21 mil 通过挖矿和 PoS治理线性发放,没有增发或销毁之说。
    一只胡萝北 管理员 回复Keikei 发表于2019-04-29 17:48:07
    Q: 1. Currently, staking is starting to gain popularity. DCR is a veteran in this field. Its technology has also been acknowledged by many developers. However, it seems to lose its steam in community operation. Do you have any promotion plan in the near future?
    2. Although staking is springing up, debate grows over whether destroying is more valuable than issuing more tokens among the Cosmos community. So what do you think? Will DCR develop team stick to your initial vision?

    DCR的社区自治模式很好, 但共识更改时间过长(至少2个月), 如果发生重大BUG, 如何保证能在短时间内修复并应用?
    DCR的PoS模式也很好, 但票锁定了大量的币, 造成流动性问题, 如何解决?
    DCR的开发过慢, 单单一个DEX去掉就提出来了, 现在还没什么动静, 怎么解决这个问题? 而且iOS, Android端最近才上线, 如何加快开发进程?
    DCR倒底解决了什么问题? DCR倒底能为社会贡献什么? DCR的主要应用方向是什么? 更进一步说, 区块链倒底在解决什么问题? 这些其实很难讲清楚, 如果开发者都不清楚, 那再造一个币有什么用呢?

    DCR self governance model is great but consensus changes take too long (at least 2 mths), if there are huge BUG, how do we guarantee shortest time fix and apply?


    DCR PoS model is great too but it locked up huge volume of coins causing liquidity issues, how is this resolved?


    DCR development is too slow, in the case of DEX, its been mentioned since last year but no action till now. How do we resolve this ? Also iOS and Android are only available recently, how can the development speed up ?

    What problems do DCR solve ? What can DCR actually do to the community? What is the main application of DCR? Further into this what does blockchain resolves? These are difficult to explain and if developers are not clear then what for to have another coin?
    DecredGuang 版主 回复6255b91558 发表于2019-04-29 19:25:19 嘉宾
    这个在社区里是讨论过的。如果有重大致命的漏洞,开发可以做个尽量小的改动先推出修复漏洞,至少降低/解除bug的危害。之后让所有人升级,同时走正常路线提案修复链上投票,实施完整解除bug的方案。

    PoS 是治理重要的一环,虽然锁定币对流动性有一定影响,但并不是低流动性的根本原因。这个可以参考其他PoS币种,并不能说所有PoS币种都有流动性问题。要解除根本问题是必须发展整体生态,有需求有供应。解决流动性问题的短暂方案也可以是一些花钱邀请做市商加入提供流动性,但这个还是需要投过提案系统投票。

    DCR 一直坚持开发质量而不追求速度,是因为主链底层的开发和应用层开发是不一样的要求。主链讲求稳定,安全。当然如果更多开发人员能参与项目开发会对项目进展速度有所提升。DCR 承包商模式其实非常鼓励更多的开发者参与。

    DCR 主要解决的是治理问题。在去中心化的治理模式中,DCR 是这么多项目中领先的。DAE 是区块链里非常新颖的实验,现在正在讨论的各个提案都是达成去中心化自治实体 DAE 方向前进的小步走。距离实现当然还有很遥远的路程但是在我看了 DCR是最有机会实现的一个项目。

    DecredGuang 版主 回复hmtabc 发表于2019-04-29 17:24:11 嘉宾
    DCR 的 PoW+PoS 混合共识机制,是在已经证明有效的 PoW 层面上增加 PoS 验证层。持币者可以通过锁定币换取选票(即买票),通过PoS 投票来确保矿工不作恶。

    投票分为一下几种。
    1. 每个区块会随机抽出 5 张选票,这些选票将会根据区块是否作恶作出投票。
    - 如果区块投票的票数少于3张,表示该区块没能达到PoS层面共识,该区块将不会被记录到区块链中,而矿工奖励将被剥夺。
    - 如果区块投票票数多于三张而否定票数多于3张,即该区块被 PoS 认定为作恶区块,矿工奖励被剥夺并且区块中的普通交易将被撤回。
    - 如果区块投票数多于3张并同意票多于3张,即该区块被 PoS 认定为合格区块,矿工才会获得奖励。

    由于矿工必须承担矿机即运行矿机的开销,区块奖励是矿工获利的重要一环。增添的 PoS 层面非常有效的阻止矿工作恶,或让矿工作恶的成本大大提高而起到防止作用。

    PoS 选票是随机抽取,而选票是通过锁定币购得,这个过程是非常去中心化而且大大提高攻击 DCR 的成本。
  • clobber 船员 发表于2019-04-26 10:04:29

    关于社区治理,我提一个问题:
    关于ticket splitting这个事情,不知道官方是如何考虑的?如果官方钱包支持ticket splitting,那会进一步抽干流动性,很有可能导致所有的币都进入票池 ,如果不支持ticket splitting,那随着票价上升,普通人买不起一张票会导致,会形成权利集中。不知道官方对ticket splitting这个功能是什么态度?官方中立?支持?或反对?

    我们知道POS的收益是为了鼓励大家参加社区治理进行投票,既然不满一票的人还渴望进行社区治理,那是否可以给予分票治理权(可以参与投票),但是没有POS收益? 这样既能解决社区治理的问题,又不至于导致流动性枯竭的问题。

    1 question about governance :
    What is the official team view about ticket splitting? If official wallet support ticket splitting, it will further withdraw liquidity, and possibly direct all coins into the ticket pool, if not to support ticket splitting, with increase in ticket price, ordinary users cant afford a ticket and cause the power centralization. What is the teams view on ticket splitting? Neutral? supportive or against it ?

    We know PoS rewards are to encourage people to participate in voting for governance, if people who doesnt own a ticket's worth like to participate in governance, should there be split ticket to participate in governance (participate in voting) but without PoS rewards? This can resolve community governance issue while not causing liquidity dryness.
    DecredGuang 版主 回复clobber 发表于2019-04-29 17:45:46 嘉宾
    官方是支持分票的,但目前分票的使用占全部选票很少的部分。至于会不会抽干流动性还是一个未知数,是否有这么多人愿意锁定币换取投票权?选票价格的浮动影响奖励的收益百分比,到了奖励不在吸引自然就会少人购票了,这是票价里独有的经济效应。买票是一个信任,要求未知期限锁定币换取投票权,票价自动调整,愿意投入的都可以买票,这不会形成权利集中,而是设计之一, 让愿意投入的持币者多一分话语权。

    社区治理设计是让持币者锁定币换取投票权,这样投票才会慎重,因为作出的决定会直接影响自己锁定的币的市场价值。如果没有锁定币也能对治理作出决定,这样无法防止投票者作恶,投向坏的选择。

    Ticket splitting will lower the access barrier to PoS voting, but there is no proof that it will increase the quality of governance decisions in the short term. We also lack the development capacity to simplify the ticket splitting process without delaying other (more important) projects within Decred. For these reasons, I am happy with the existing ticket splitting solution:

    currently seems like atomic swap development has stopped, and on cross chain operations, seems like Cosmos and polkadot has better implementation. Hope to see below points on DCR structure re-org

    3. support new economy model

    It is important to realize that Decred is a decentralized digital currency, used to store and transact value without censorship, confiscation, or inflation. Although atomic swaps are a very interesting technology, it is a side project. The focus of Decred is to build a solid Layer 1 blockchain.

    The Decred atomic swap tools can be found here: https://github.com/decred/atomicswap To put it simple, atomic swaps allow for trustless, p2p trade between two different blockchain users (we will use atomic swaps to build the Decred DEX, for example).

    What the tech projects you mentioned do, is act as trustless relays between different chains or projects to create interoperability (not directly p2p). This is a very different use case.
    DecredProject 版主 回复Noah_Pierau 发表于2019-05-04 15:27:11
    重要的一点是Decred是一个去中心化数字货币,用于存储和交易价值,无需被审查,没收或通货膨胀。虽然原子交换是一项非常有趣的技术,但它是一个侧面项目。 Decred的重点是构建一个可靠的底层区块链。这里可以找到Decred原子交换工具:https://github.com/decred/atomicswap。
    简单来说,原子交换允许在两个用户之间进行无信任,p2p交易(例如,我们将使用原子交换来构建Decred DEX)。 您提到的技术项目所做的是,在不同的链或项目之间充当无信任的中继,以创建互操作性(而不是直接p2p)。 这是一个非常不同的用例。

    1. To make sure that Decred will survive and thrive in the long run, Decred has both on-chain and off-chain governance systems to direct the project. More information on governance: https://docs.decred.org/governance/overview/

    2. If you would like to participate in the voting system, you need to demonstrate that you have skin in the game and obtain voting tickets (unique for Decred). Access to tickets is based on supply and demand. Learn more here: https://docs.decred.org/proof-of-stake/overview/

    3. The hybrid PoW+PoS consensus mechanism of Decred creates multiple significant differences compared to pure PoW currencies such as Bitcoin. Examples are formal governance, the ability to keep PoW miners in check, and sustainable funding. More benefits are summarized here: https://medium.com/decred/why-decred-let-the-community-tell-you-5479929e35d2

    DCR已经实现了闪电网络和原子交换,我相信这些都有利于DCR后期的发展。但是目前区块链有个大热点是跨链,典型例子为波卡和COSMOS,麻烦请问下DCR的原子互换技术和波卡等的跨链技术有和区别?是技术实现不同而已还是具体的应用场景就不同?谢谢。

    DCR has already implemented LN and atomic swap, i believe these are beneficial for DCR developments later. But at the moment one hot topic is cross chain, typical projects like Polkadot and COSMOS for example. Can i know what is the difference between DCR atomic swap in cross chain vs tech in projects like polkadot? Is it just different implementation or it is different application ? Thanks

    The Decred atomic swap tools can be found here: https://github.com/decred/atomicswap

    To put it simple, atomic swaps allow for trustless, p2p trade between two different blockchain users. What the tech projects you mentioned do, is act as trustless relays between different chains or projects to create interoperability (not directly p2p). This is a very different use case.

    While the two are very different and not comparable, it is good to note that atomic swaps have been tested for a longer time, while interoperability is still experimental.

    面对投票价格越来越高,对区块链有兴趣的新手纵使明白 Decred 的治理理念,但却因缺乏买选票的资金未能尝试去参与投票感到可惜。虽然知道有 Ticket Splitting 可以集成其他用户的分票,但这需要下载第三方软件去进行操作,这样欠缺技术的小白会担心操作失误及软件安全的隐忧而脚步。我想问的问题是,将来 Ticket Splitting 会否整合到 Decred 官方钱包预设功能之中,简化操作,让更多人可以尝试去参与投票。谢谢!Dsjqvx8xhEqRnKQk7VYkg6LGWNW4kAoZFrt

    With higher ticket prices, even if newbies understands Decred governance model but they are not able to participate because of lack of funds to purchase ticket. Even though there are Ticket splitting, that requires downloading third party software to execute, less technical users will worry about mistakes in operations or software security and thus not participate. My question is, will ticket splitting be integrated into Decred official wallet, simplify the operations so more people can participate in voting. Thank you!

    选票价格昂贵是社区对于DCR 治理信任的一种体现。将资金锁定来换取投票权,参与对项目发展方向的决定。DCR PoS 设计就是让持币者拥有投票权,自然的这个投票权会落在最愿意投资并锁定币的参与者。

    分票软件也是开发开源的软件,可以放心下载使用的。当然之前聊天室里面开发也多次提过分票整合到官方钱包是计划的一部分,当然这些整合都需要时间。目前分票的数量占了全部选票非常小的一部分,可能分票的需求也不是太明显。

    用户可以参与帮忙测试分票软件,多提宝贵意见,这样就能加速完善分票功能并发现任何漏洞,提高参与率并让开发者明白分票是个刚需,而早日整合到钱包中。

    In essence, Decred is similar to Bitcoin and Litecoin: you can store and transact value without censorship, confiscation or inflation. This is enough for most newcomers.

    The governance system is there to govern the project, to make sure that Decred will survive and thrive in the long run. If you would like to participate, you need to demonstrate that you have skin in the game and obtain voting tickets. Access to tickets is based on supply and demand.

    Ticket splitting will lower the access barrier, but there is no proof that it will increase the quality of governance decisions in the short term. Therefore, it is not a priority at the moment. We also lack the development capacity to simplify the ticket splitting process without delaying other (more important) projects within Decred. If you know Go (golang) developers that are willing to work on this issue, feel free to bring them on board: https://docs.decred.org/proof-of-stake/ticket-splitting/

    is DCR confident to compare with BTC ?
    DecredGuang 版主 回复DecredProject 发表于2019-04-29 18:19:06 嘉宾
    首先 DCR 的目标不是为了取代比特币。另外多个币种共存也是有可能的。
    但是机制上来说,DCR 解决了比特币几个核心,不容易解决的问题。
    第一,持续的资金问题 - 很多比特币开发都是资源性工作,依靠捐款或投资者的资助获得工资。DCR 通过分配 10% 的区块奖励设立一个社区基金,作为开发和持续发展的资金,让开发可以不受赞助商影响进行开发。
    第二,治理决定问题 - 比特币在决定方案上面的治理模式比较模糊,比如是否启动 Segwit,是否增大区块等课题缠绕多年仍未得到确定的决定。DCR 的链上治理有效的解决这个问题,让持币者作出投票决定。而链上投票决定直接锁定启动新功能。
    第三 PoS 层面增加了一层防护,防止矿工作恶,将关于区块链的决定归还给持币者。参考之前发布过的文章, DCR 的混合机制对比纯PoW 机制,作出51% 攻击的成本是要高出20倍。

    同时 DCR 是目前区块链项目中治理方面领先的项目,链上治理,提案系统,去中心化管理社区资金,承包商模式 都是DCR优越的地方。DCR开发团队的实力也是相当的,当初参与比特币开发,还有闪电网络和原子交换的基础设施都是DCR开发者贡献很多的项目。

    Bitcoin and Decred are different social contracts. They can coexist. Both projects have their own rules that are based on fundamentally different beliefs:

    For people who believe that "the market" makes the best decisions, Bitcoin may be the right choice. During any contentious change, the network may split in two or more forks that will compete for financial and social support of PoW miners, developers, investors and exchanges.

    For people who believe in collaboration, who aspire to pursue the common good, and who are willing to align themselves behind the general will of the decentralized voter collective, Decred may be the right choice.

    What is for sure: the values of freedom and sovereignty are present in both projects and both have a high chance of survival in the long run.

    DCR现在可以在那些国家使用,支持那些商店?
    DCR投票方式有想过改变吗?50%POS+50%POW?
    投票会减少DOC持有量如何让更多人参与吗?

    Which country can we use DCR now and which shops ?
    Will DCR change the voting to 50% PoS + 50% PoW?
    Will voting decrease holdings requirement to allow more participation?

    目前的实际支付应用并不多,但 DCR 用于支付目前也不是主要目标。

    DCR 的区块奖励目前是 60% 矿工 PoW,30% PoS 和 10% 社区基金。
    - 社区基金的目的是保持持久的运营和开发经费,让项目至少在近年都有相应资金维持开发的推广。
    - PoS 是为了保持各参与者不要作恶,保证区块链的运行
    - PoW 的区块奖励是最高的,这是因为矿工是保持区块链运行,记录交易,生成新区块,也是生态里最重要的一环。矿工运营的开销包括矿机,电费,技术都是很大的开销,所以获得大部分奖励是非常合理的。
    奖励的分配我觉得短期内不太可能会更改,当然DCR 最大的优势就是治理,如果社区共识认为更改奖励机制是很重要的,社区也可以发动更改,通过投票表决。

    选票价格昂贵是社区对于DCR 治理信任的一种体现。将资金锁定来换取投票权,参与对项目发展方向的决定。DCR PoS 设计就是让持币者拥有投票权,自然的这个投票权会落在最愿意投资并锁定币的参与者。就和公司只会听最大股份的意见一样,如果想认真参与DCR 治理只能存币买票了。 加油哦。

    If you dig deeper, there are many stores that already accept DCR. However, there is no directory where we collect all the stores in one place.

    Payment processors that let you accept DCR in your store:
    https://globee.com/
    https://coingate.com/accept/dcr/decred
    https://blog.coinpayments.net/coin-spotlight/decred

    One example of a store that accepts DCR: https://www.cryptoemporium.eu/

    两个问题:

    1.DCR的设计和技术都很好,但是目前都使用率很低,DCR设计的区块链大小是384K左右,但是实际上目前每个区块只有几K到十几K,不知道对提升使用率方面有什么规划和想法。

    图一 可以看出现在每个区块都很小,可以说明使用者很少

    图二 是区块高度339206,只有12笔交易,其中有5笔vote 5笔tickets,也就是说真实的使用率其实更低



    2.DCR的VSP除了排名靠前的,剩下的几乎都不赚钱,都是在贴钱运营,不知道社区对这个问题这么看。

    2 Questions :

    Q 1.DCR design and technicals are good but the current use rate is very low. DCR design block size to be around 384K but every block is only few K to tens K at the moment. What is the plan to increase usage.
    image 1 shows everyblock size is small - means usage is very low.

    image 2 is block 339206,there were only 12 transactions, including 5 votes and 5 tickets, which means the actual usage rate is even lower.

    Q 2.DCR's VSP are not profitable and running at a loss except the top few VSPs. What is community's view on this issue.
    Noah_Pierau 版主 回复zhaogang 发表于2019-04-30 01:22:26 嘉宾
    1. We are aware that usage of Decred / DCR is lower than projects such as Bitcoin or Litecoin. This is in part because Decred is a much younger project, and in part because BTC and LTC have stronger network effects. We all share the responsibility to make Decred stronger. The more people participate, the stronger the Decred network will be. My plan to increase usage is to keep promoting Decred, what is your plan?

    2. This is the first time I heard about it, I assume you are talking about losses in terms of fiat? (since the VSP fee should ensure that operators earn more DCR) The way I see it, VSP operators are responsible for their own operations. Their first option is to increase the user base of their VSP (via marketing, promotion, by offering additional services, etc.). Their second option is to help increase the price per DCR, so the DCR they own through fees is worth more fiat. This ties back to the first question: we all share the responsibility to make Decred stronger.
