  1. Hello everyone With more and more contracts for market makers coming, these addresses are confusing. If the wrong address you send token to, you can't find it back.So I suggest adding a transfer interface for each market maker's contract on the wallet.enumivo.com, just avoid the same mistakes. 大家好 随着做市商的合约越来越多,这些合约地址非常容易混淆。如果你将token发错了地址,就无法找回它了。所以我建议能在wallet.enumivo.com上增加做市商合约的转账界面,以免再发送类似的错误。

    半年内 enu不到5元,直播吃鸡

    半年已经过去了,楼主该履行承诺了
  3. 各位大佬好 我准备搞一个能让每个人自助创建token的dapp,不需要额外部署合约。使用方法是发送3 enu到合约账户tokencreator(3enu用来买内存ram),在memo里填写要发行token的数量和符号,合约会创建token并发送给你。 合约我已经创建好了,能否请各位大佬帮我检查下合约是否安全呢,合约代码已经开放: https://github.com/smakeit/tokencreator 浏览器版的已经完成(需要安装Ironman)。地址: https://smakeit.github.io/dapp/enutoken/ TP钱包版的已经完成。
  4. Hello erveryone I want to create a dapp that everyone can create and issue a token by themselves, without deploy a contract. The way to use it is to send 3 ENU(for buy ram) to the contract tokencreator, and fill in the max supply and symbol of the token you want create in the memo. Then the contract will send you the token. The contract I have already created it, please help me to check if it is safe. Code of contract is opened : https://github.com/smakeit/tokencreator Browser version has been completed(need to install Ironman).website: https://smakeit.github.io/dapp/enutoken/ Mobile wallet version On TokenPocket is done.

  10. 中文翻译原帖: https://mp.weixin.qq.com/s/sxk_GRSgSxPPkjWhHcQHCA 全民基本收入(Universal Basic Income)是指全体公民都能定期的、无条件的收到帮助他们支付生活费用的津贴。实践已经表明,UBI项目确实能够降低住院率、犯罪率和贫困率。尼克松总统(Richard Nixon), 托马斯.潘恩(Thomas Paine), 马丁.路德.金(Martin Luther King Jr.),密尔顿.弗里德曼(Milton Friedman)都是有名的UBI项目支持者。 UBI项目一般被理解为一种政府补贴,通过补贴把钱直接发到每个人手中,然后所有的钱都会回流到市场中来,正如美联储的量化宽松政策让钱通过银行再回流到市场中来。 然而,加密货币的发展让我们以一种新的方式,即全球化的、免信任的、民主化的方式来实施UBI项目,而且不需要政府的参与。 最近涌现出了一批基于区块链的UBI项目,它们都处于项目的早期。除少数项目外,大多数项目还没有一个公共的产品,如果你对这类项目感兴趣,你可以看看下面这些项目。 Mannabase: SwiftDemand: 还有Solidar(界面类似于Facebook messenger 里的聊天机器人) 我们对这些项目的可能性充满好奇,并且也在思考一些重要的问题,比如发行代币的复杂性以及防止欺诈账户。 钱从哪来? 当通过区块链来实施UBI项目时,最初的钱是从哪儿来的呢? 大多数UBI区块链项目都是以通证的形式来发行自己的货币。也就是说,它们通过铸造新的货币来创造新的价值,而不是将已有的钱再流入到市场中。这里存在的挑战是,新创造出来的货币起初是没有价值的,直到有人接受这种货币,然而UBI项目的初衷是为人们创收,以便于人们支付房租、学费以及日用杂货。因此,每个UBI项目都要使得它们的货币有价值。 这些项目通过围绕它们发行的代币来建立一个经济体使得其货币有价值,在这个经济体中,人们可以互相兑换或者用这些代币购买商品和服务,Nick称这就是构建“最小可行经济体”(Minimum Viable Economy)。 构建一个最小可行经济体:杂货商和批发商 构建一个最小可行经济体的初衷是围绕其发行的代币来建立一个生态系统,代币的持有者在这个生态系统中可以用代币购买商品或服务,或者兑换其它货币。 要使得上述情况发生,这个项目就需要激励杂货商和批发商接受代币这种支付方式。 SwiftDemand可能是目前UBI项目里在开发商户方面做得最好的。该项目是通过将杂货商发展成为其项目所在社区的成员来扩大市场的。项目社区内的任何人都可以卖东西。 项目社区内的任何人都可以用它的代币Swift来买东西。 UBU项目(beta)则是通过为杂货商提供工具以便他们能够更容易支持UBU代币进行支付。Enumivo项目(pre-beta)则是通过EOS的分叉来建立自己的公链,目的是希望开发者在他们的公链上开发Dapp可以接受他们的代币$UBI。 如果确实有许多人持有某一种代币,那么去说服杂货商接受这种代币是很容易的。正如信用卡的使用,即使杂货商不喜欢信用卡,因为信用卡的发卡行会向商户收取一定的手续费,并且还要在店内提供相关的硬件设备,但它们还是有动力去接受信用卡支付,因为有许多人在使用信用卡。 要形成这种网络效应,许多UBI项目都有推荐机制来奖励给其带来新用户的人。比如UBU项目,就给推荐人奖励1000个UBU,给被推荐人奖励500个UBU。 有些项目不是采取一次性奖励的方式,而是只要用户在项目的网络中就给予持续的奖励。比如Frink项目(beta),计划无限期的给推荐人额外的10%代币奖励,Mannabase项目计划在一年内给推荐人额外的100%代币奖励。这样做的目的都是鼓励推荐人介绍高质量的用户,使他们能够在项目的网络中停留较长的时间。这样又产生了一个有趣的问题,那就是高额的代币推荐奖励是否会促使人们推荐造假来薅羊毛。 一般来说,这些项目增长到一定程度后,项目的推荐机制就失效。比如Solidar项目计划在其网络用户达到15000人时,其代币推荐奖励就减半,并且每次项目网络用户翻一番了,其代币推荐奖励再减半。 构建最小可行经济体:货币政策 这些项目还需要鼓励人们花费它们的代币。这些UBI项目可以制定一种货币政策使得代币的持有者更愿意花费代币而不是屯着这些代币。 有两种方法可以达到这种目的:一种是征收逾期费(一定数量的持有代币自动消失),另一种是增加代币供应量(每个持有的代币就相应的贬值)。这两种方法都可以鼓励代币持有者花费这些代币,否则的话,他们持有的代币都会相应的贬值。 UBU项目就是采用了征收逾期费的方式:用户的UBU钱包内的余额每年都会减少1%。Circles项目采用了增加代币供应量的方式:该项目计划按照每年5%的比例增发代币。最引人注目的是Solidar项目,该项目按照每年20%的比列征收逾期费。 另一种鼓励人们花费项目代币的方法是对每个账户单次持有的代币数量封顶。为了接受更多代币,每个账户都要将已有的代币取出或者花费掉。以SwiftDemand项目为例,该项目只允许账户一次持有7天的无偿收入。 构建最小可行经济体:流动性 另一种为代币制造价值的方法就是提供流动性,也就是说,让代币的持有者能够兑换其它货币,一般是法币,比如美元。 要使代币具有流动性,就需要有人愿意出钱从代币持有者那儿购买。Big Foundation项目(beta)为购买其代币的人提供奖励来创造流动性。 Greshm(pre-beta)项目通过持有储备的美元来发行其代币XGD,这些代币都由项目持有的美元来担保(需要说明的是该项目不是建立在区块链上的,而是有自己的系统)。最初的用户和杂货商就提供了项目的流动性,他们可以将代币兑换成等额的美元。 Greshm打算刚开始维持其代币与美元1:1的兑换比例,然后再提高代币兑美元的比率。这就允许他们把新的资金投入到流通中来(这种模式以前在美国经济中存在过,即联邦银行通过借出超出储备金的钱来创造新的资金,一直到某一个 借出资金/储备金 比例)。 Democracy Earth项目的分发则采取了另一种更有趣的方式。因为该项目发行的代币拥有和投票权一样的作用,人们更愿意去购买这种代币。Democracy Earth项目(beta)是一个治理平台,购买代币就意味着购买投票权。该项目的事先声明中提到项目中的所有组织可以设置宪法式的智能合约,这样就可以确保在每一个议题上做到一人一票,也防止了参与者购买投票权。 身份确认与反欺诈 在UBI项目分发代币前,他们首先需要确认每一个参与者是真实的人,并且每个人都只有一个账户。这就防止了“女巫攻击”的欺诈行为,即用户在封闭的系统中创建多个身份,彼此互相验证和信任。如果每个用户都可以创建多个账户来增加他们所获得的收入,这会消解公众对代币价值的信任,并且会贬低其价值。这还会损害项目的初衷,即每个人在项目中都是平等的。 解决这个问题有两种方法:投票和社会信任 第一种方法是通过投票让社区内的成员来验证新加入的人。在Democracy Earth项目中,新成员都要经历一个和其他之前已经验证过的社区成员进行验证的过程,以便能够加入该项目网络。他们实际上计划让每个参与者定期重复这个过程,以阻止一些僵尸账户。 第二种方法是依赖于来自现实生活中的信任关系。Circles项目就采用这种有趣的方法。在Circle项目中,每个新参与者都以自己的个人货币形式来发行UBI支付。这种代币刚开始是不值分文的,因为没人愿意用它来进行兑换。为了使他们的账户余额有价值,该项目的参与者就需要相信其他人发行的代币,并且愿意与他们相互兑换。引用Circle项目白皮书的话,“特定个人代币的价值可以通过多少其他账户信任它来度量,这也就意味着对于新用户来说,与那些在网络中已经建立了可信关系的人相比,其拥有的代币价值就低些。这也意味着随着时间的推移,新用户创造了更多的信任关系,他们的代币会更有价值。” Enumivo项目计划将上述两种方法结合起来。想要加入该项目的人必须找一个已经在该社区内的成员来支持自己。要支持某个人,社区成员需要持有200个代币,其他社区成员有30天的时间来投票决定是否接受这个人。 也有一些独立的身份项目,如uPort和Civic,未来的UBI项目可以借鉴这项项目的得失。一般说来,我们非常感兴趣了解更多的能体现自我主权的身份项目,这项项目可以实现像UBI这样的去中心化。 这些项目都是可持续的吗? 大多数UBI项目都通过两种方式来促进自己的发展,一种是持有一定比例的自己发行的代币(大多数项目都如此),或者是收取手续费(有一些项目如此)。 我看好这些收入来源,是因为它把核心团队的利益和用户的利益统一起来了。核心团队把网络和通证经济发展得越好,他们持有的代币就越有价值,通过交易收取的手续费也就越多。 总结 区块链技术在UBI项目中的应用是让我们感到非常兴奋的,我们也希望能够了解不同的UBI项目是如何结合区块链技术并实施的,如果你也在从事与UBI项目相关的工作,我们很愿意了解你的项目进展情况,我是丹尼(Dani),我的邮箱是dani@usv.com
  11. original post: https://www.usv.com/blog/an-overview-of-blockchain-based-universal-basic-income-projects An Overview of Blockchain-Based Universal Basic Income Projects JUL 10, 2018 Universal Basic Income (UBI) is the idea that citizens receive a regular, unconditional stipend that helps them cover their cost of living. Previous UBI experiments have shown to reduce hospitalization, crime and poverty rates. Richard Nixon, Thomas Paine, Martin Luther King Jr. and Milton Friedman were all vocal proponents of UBI. UBI has traditionally been imagined as a government subsidy that would put money back into the economy by giving it directly to people (as opposed to quantitative easing where the Federal Reserve puts money back into the economy through banks). The development of cryptocurrency, however, now gives us a way to implement UBI in a global, trustless and democratic way without the need for a government to implement it. Recently there has been an emergence of a handful of blockchain-based UBI projects. They are all very early. Most of them do not yet have a public product, but a few do, if you’re curious to try some out, a few you can check out are Mannabase: SwiftDemand: and Solidar (implemented as a chatbot on FB messenger). We are intrigued by this possibility and are wondering about some key issues, such as the complexities around issuing new currencies and preventing fraudulent accounts. Where does the money come from? When blockchain projects implement UBI, where does the initial money come from? The majority of the UBI blockchain projects issue their own currency in the form of tokens. That is, instead of recirculating existing money in the economy, they generate new value by minting a new currency. The challenge is that while the idea behind UBI is to provide real income that can be used for paying for things like rent, tuition and groceries, newly invented currencies are initially worthless until someone accepts them. It is up to each UBI project to make their currency worth something. Projects do this by building an economy around the currency where people can exchange and use their tokens to buy goods and services. Nick calls this building a ‘Minimum Viable Economy’. Building a Minimum Viable Economy: Vendors & Merchants The idea behind a Minimum Viable Economy is to build enough of an ecosystem around a token so that its holders can use it to buy goods and services or exchange it to other currencies. For this to happen, the project needs to incentivize merchants and vendors to accept the token as a form of payment. SwiftDemand is probably the UBI project with the most developed marketplace so far. Their hope is to seed the marketplace with vendors that are participants in their UBI community. Anyone in the community can submit something to sell: And then anyone in the community can buy those things using the Swift token: projectUBU (beta) is building tools for vendors to be able to easily add support for their UBU token. Enumivo (pre-beta) is building their own blockchain (a fork of EOS) with the goal of developers building dapps that accept their token, $UBI. It is easier to convince vendors to accept a token if there are a lot of people that hold the token. A good analogy for this is the credit card: even though vendors dislike credit cards because they are expensive and require extra in-store hardware, they are incentivized to accept them because so many people have them. To seed this network effect, many UBI projects have referral programs to reward people who bring in new users. projectUBU, for example, rewards 1,000 UBUs to the referrer and 500 UBUs to the referee per referral. Some projects, instead of doing a one-time bonus, continue to award the referral bonus as long as the referred person stays in the network. Frink (beta), for example, plans to indefinitely payout an additional 10% to referrers, and Mannabase plans to payout an additional 100% to referrers for one year. The idea is to incentivize people to refer “high quality users” that will stay in the network for a long time. An interesting question is whether a high referral bonus will increase the incentive and potential for referral fraud. These referral programs are often set to expire when the network grows to a desired size. Solidar’s program, for example, is scheduled to reduce the bonus by 50% when the network reaches 15,000 users and then again every time the network size doubles. Building a Minimum Viable Economy: Monetary Policy Projects also need to incentivize people to spend their tokens. UBI projects can build in monetary policy that makes it more attractive for token holders to spend the tokens than to hold them. There are two ways to do this: demurrage (some amount of held currency automatically dissipates) and by growing the money supply (so that each held token is now worth less). Both accomplish the same goal of incentivizing token holders to spend their currency, otherwise their held currency will lose some of its value. projectUBU is one of the projects utilizing demurrage: 1% of all UBU wallet balances dissipate every year. Circles is one of the projects planning to mint more currency: they plan to grow their money supply at a 5% annual rate. The most dramatic of these programs is Solidar, which has an annual 20% demurrage rate. Another way projects incentivize people to spend their tokens is by capping the amount of tokens any account can hold at one time. In order to receive more tokens, participants need to withdraw or spend the tokens they’ve already received. SwiftDemand, for example, only allows accounts to hold 7 days of unclaimed income at a time. Building a Minimum Viable Economy: Liquidity Another way to create value in tokens is to provide liquidity - aka the ability for a token holder to exchange the token for another currency, usually fiat, like USD. For there to be liquidity, there needs to be someone who wants to buy tokens from those that hold it. One project called Big Foundation (beta) is seeding liquidity by paying people a bonus for buying the token. Greshm (pre-beta) holds a reserve of USD and issues currency called XGD backed by that USD reserve. (Note that they are built on their own system and not on blockchain). That provides initial participants and vendors with a source of liquidity - they can cash out and receive an equal amount of USD for their XGD. Greshm plans to maintain a 1:1 peg to the USD at first, and then increase the ratio of XGD to USD over time. This will allow them to put new money into circulation. (This model exists in the traditional US economy where federal banks can create new money by lending out money they don’t have in reserve up to a certain lended_money:money_in_reserve ratio.) Another interesting approach here is Democracy Earth’s distribution program. Because their currency has immediate utility as a vote, there are more likely to be buyers of it. Democracy Earth (beta) is a governance platform, and buying currency can mean buying power. The caveat is that organizations built on Democracy Earth can set their constitutional smart contracts to limit only one vote per person per issue, which inhibits the ability for participants to effectively buy votes. Identity Verification & Anti-Fraud Before a UBI project can hand out tokens, they first need to verify that each participant is a real person, and that each person is limited to a single account. This prevents cheating via ‘Sybil attack’ where a user creates multiple identities that all trust and validate each other in a closed system. If every user could create multiple accounts to increase the amount of income they received, it would dissolve the public trust in the value of the currency, and depreciate its worth. It would also undermine the spirit of the project where in everyone gets the same amount. There are two main ways that UBI projects are solving this: voting and social trust. The first way is allowing members of the community to vote to verify a new participant. On Democracy Earth, for example, new participants have to go through a validation process with other previously validated community members in order to be able to join the network. (They actually plan to have every participant repeat this process periodically in order to prevent abandoned accounts). The second way is by relying on trust relationships from the real world. Circles (pre-beta) does this in an interesting way: On Circles, each new participant is issued UBI payouts in their own personal currency. That currency is not worth anything because no one agrees to exchange it yet. To make their account balance worth something, Circles participants need to trust each others currencies by being willing to exchange them. From the Circles documentation: "The value of a specific personal currency is a measure of how many other accounts trust it. This means that users who are new to the system and don’t have many trusted relationships have a less valuable currency than someone who is well-established in the network. It also means that the currency of new users gets more valuable over time as they create more trust relationships." Enumivo plans to do a combination of the social graph and voting solutions. People who want to join Enumivo will have to find someone already in the community to sponsor them. To sponsor someone, a community member stakes 200 tokens (10 weeks worth) and then other community members have 30 days to vote on them. There are also standalone identity projects like uPort and Civic that future UBI projects could potentially leverage. Generally we are very interested in learning more about self-sovereign identity projects that could enable decentralized programs like UBI. Are These Projects Sustainable? There are two ways most UBI projects fund their development: by holding a percentage of their tokens (most UBI projects do this), and by collecting transaction fees (some UBI projects do this). What I like about these revenue sources is that they align the core team’s interest with their users’ interests. The better the core team grows the network and token economy, the more their tokens are worth, and the more transactions there will be to collect fees on. Wrapping Up One of the applications of blockchain that we are very excited about is UBI, and we hope to keep learning about how different projects are implementing it. If you’re working on something in this space, we’d love to hear from you. Reach out, I’m dani@usv.com.
