区块链世界自诞生以来，一直伴随着“挖矿”的概念，比特币因为挖矿的产生方式而火热，而因为代币本身具有价值产生了中心化的矿池和矿场。今天链茶馆采访到了新一代全新共识算法的区块链项目Ulam社区发起人刘辉，他将从自己多年的币圈经历讲起，告诉我们为什么现在需要新的共识算法去完善区块链挖矿机制。
Since its inception, the block chain world has been accompanied by the concept of “mining”, which Bitcoin is hot because of the manner in which the mining is generated, and because of the value of the tokens themselves, the ponds and mines have been centralized. Today, the chain teahouse interviewed the Ulam community founder of the new generation of new consensus algorithms, Liu Fai, who will tell us why a new consensus algorithm is now needed to perfect the chain mining mechanism.
币圈“活化石” 曾经错失多次创业机会
初见刘辉，他穿着朴素的牛仔裤、宽大的休闲卫衣，戴着前卫的半框架眼镜，看上去是一名典型的中年创业者。但他却不是想象中不苟言笑的严肃模样，见到链茶馆团队满面春风热情欢迎，夹杂着“京片儿”的谈吐马上拉进了我们这群后辈们跟他的距离。 I first met Liu Fai, who was wearing simple jeans, wide-ranging recreational suits, and half-frame glasses of the front guard, and looked like a typical middle-aged entrepreneur. But he was not as serious as he thought he was. He saw the chain teahouse team with a warm welcome, and the talk of "Kyochi" immediately pulled us into the distance with him. 刘辉算是北京最早接触区块链和币圈的一批人，与火币李林、OKEx徐明星等都是旧相识，2013年开始就入局了区块链创业，并曾经获得李笑来两次投资，堪称币圈的“活化石”。 Liu Hui is the first person in Beijing to touch the chain of blocks and the ring of coins, known as Li Lin, OkEx Xu and others, and has entered the chain since 2013 to start a business, and has twice invested in Li's laughter as a “vibrous fossil” of the currency ring. 刘辉作为圈内的老人，给我们讲起了他如何错过十亿美金的故事。2013年刘辉跟一位朋友合伙想搞教育实验，针对于开源软硬件这个主题每周六在北京进行集会。借着这个集会，刘辉团队结识了李笑来，他每周会来为大家讲解币圈和区块链的故事，后来频率加大到每天都讲。当时那个时间点，李林、徐明星都来听李笑来讲区块链，但是刘辉却因为大连孵化器的事情在忙，而且内心对于区块链的认知也不深，觉得没有太大的前途，就没有深入参与。 Liu Hui, as an old man in the circle, told us how he had missed a billion dollars. In 2013, Liu wanted to do an educational experiment in partnership with a friend on the subject of open-source software and hardware, a weekly gathering in Beijing. With this gathering, Liu's team met Li laughter, who came to tell you stories about currency circles and block chains every week, and then increased the frequency to every day. 2014年刘辉因为传统行业创业受阻，与朋友一起做起了区块链矿机生意。但是2014年也是熊市，矿机生意并不好做，矿机的利润降低但是成本不变，三个月回本都变成了奢望。2014年夏天刘辉就退出了矿机生意，并在下半年见过以太坊V神，但是由于当时V神影响力较小，说英语带有口音，英文特别好的刘辉并没有跟他有过多交流，又一次措施了与ETH合作的机会。 But 2014 is also a city of bears, where the mine business is not easy to do, where profits are lower but costs are constant, and where three months of return have become a luxury. Liu withdrew from the mine business in the summer of 2014 and met with the Ether V God in the second half of 2014, but since the V God had less influence at the time, English had an accent, English was a particularly good Liu Hui had not had much to talk to him, and yet another step was taken to work with the ETH. 2014年，矿机厂商跟交易所有很多协作会共同参与活动，刘辉也与徐明星非常熟悉，徐明星还让赵长鹏跟刘辉一起吃过饭，当时的赵长鹏还没有创建币安。虽然当时都是非常熟的朋友，但是刘辉仍然没有在区块链行业合作创业的想法。 In 2014, there were many collaborations between the miners and the exchange, Liu Hui is also familiar with Xu Sing, and Xu has allowed Zhao Changping to eat with Liu Hui, who did not create a currency. Although he was a well-known friend at the time, Liu Hui still does not have the idea of working together to start a business in the chain industry. 浸淫币圈多年的刘辉，诸如此类的事情发生很多，他平时出去参加一些会议，总会遇到一些币圈牛人问他：“辉哥，你还认得我吗？”。刘辉坦言这是他目前最不愿意听到的话了，因为这些人大多都是区块链行业的创业成功者，而自己因为犹豫、看错了方向，当时没有跟他们合作，错过了行业内很多赚钱的机会。 Liu Hui, who has been in lewd for years, has a lot of things to do, and he goes out to some meetings, and he's always met some of the coin bulls who ask him, "Do you recognize me?" Liu is the last thing he wants to hear right now, because most of them are entrepreneurs in the block chain industry, and because they hesitate and look in the wrong direction, they didn't work with them at the time, and they missed a lot of opportunities to make money in the industry. 即使区块链创业给了刘辉很多悔恨的回忆，但是他仍是看好整个行业的未来，相信仍有新的机会留给他。在2017年时候他关注到了清华大学高等研究院（数学）博士吴彦冰，他创建了一套新的挖矿共识算法，看上去更加合理和公平，又可能达到全民低门槛参与的水平。所以刘辉结识了吴彦冰，并创建了Ulam公链项目，他负责整个项目社区的组建。 Even though the block chain gave Liu a lot of remorseful memories, he looked forward to seeing the future of the industry and believed that there were new opportunities left to him. In 2017, he focused on Dr. Oh Ying Bing, at the Qinghua University Institute of Higher Studies (Mathematics), who created a new consensus algorithm for mining, which seemed more rational and equitable, and could reach a level of low-threshold participation for all. 区块链身上的好行业特点 Good industry characteristics on the 还有一个原因激发刘辉到区块链行业创业的决心，就是他坚信区块链是一个好的行业，他认为区块链具有以下几个好行业应该有的特点。 There is also a reason why Liu Hui's determination to start a business in the block chain industry has been inspired by his conviction that the block chain is a good industry and that it has the following characteristics of a good industry. 第1， 区块链行业逻辑失效，这是一个全新的领域，创业团队几乎都是新团队，没有母公司和大公司进入。全新的行业给予所有参与者的机会是一样的，让大家站在同一起跑线上，这是一场公平的竞争。 First, the block chain industry’s logic fails, which is an entirely new field, with business teams almost all new, with no parent company and no big company entering. The brand new industry gives all participants the same opportunity to stand on the same track, and it is a fair competition. 第2， 所有人对于区块链还不是很懂，刘辉认为不知道区块链是什么确实是好事情，标准说法是行业没落地。都不懂才是好的机会，因为创业团队可以边研发边学习、边探索边进步，且不用担心触及了行业的上限，因为没有人知道区块链到底能有多大作为。 Number two, everyone doesn't know what a block chain is. Liu thinks it's a good thing not to know what a block chain is. The standard is that the industry has fallen. No one knows it is a good opportunity, because an entrepreneurial team can learn while developing and exploring and progress without worrying about the industry's ceiling, because no one knows how much a block chain can do. 第三，刘辉认为一个行业要被人骂才是好行业。他谈到，大数据、人工智能、VR、AR一直在被夸是高精端的好技术，但是有一个项目做出来了吗？一个都没有，AI公司除了下棋什么都没做出来，自动驾驶Google做了10年还没做出名堂来。区块链行业动了别人的奶酪，改变了劳动关系，影响了所有行业，影响了美元的升值，所以被各行各业所有人讨厌。 Third, Liu Xi believes that a business is a good business if it is called a curse. He talks about big data, artificial intelligence, VR, AR, which has been boasted of as a high-end technology, but has one project come up? None, the company AI has done nothing but chess, has done nothing for 10 years and has not done it automatically. The sector has moved other people's cheese, changed labour relations, affected all industries and affected the appreciation of the dollar, and is therefore hated by everyone in all walks of life. 第四，年轻人能够有机会。在日本的行业规矩里，厨师进了厨房必须学徒十年，木匠需要进深山老林进修多年不能结婚。这样的职业价值观是不值得提倡的，完全摒弃了社会给予年轻人的机会，年轻人不应该妥协。而区块链行业中，大部分都是年轻人，不论是技术研发、还是市场商务，都是年轻人涌现在前线。 In Japan’s industry rules, cooks have to go to the kitchen for 10 years, and carpenters have to go to the mountains to study and not marry for many years. Such professional values are not worth promoting, completely rejecting the opportunities offered to young people by society, and young people should not compromise. 第五，好的行业不需要努力也可以赚钱。刘辉谈到英国在80年代拥有黄金十年，各行各业飞速发展，工厂的订单供不应求，那时候是卖方市场。消费者都在求着卖方提供商品，作为销售人员根本不需要工作，早上去公司报个到就出去喝茶了，钱也是大笔大笔的赚。而这样的卖方市场在现今中国传统行业中是不太可能出现的，而区块链充满着可能，虽然现在是漫长熊市，但是只要创业者找到一个能落地的创新方向，就有希望创造出卖方市场。 Liu Hui spoke of a decade of gold in the United Kingdom in the 1980s, a period of rapid growth in various industries, and a market for sellers when consumers were demanding goods from sellers, who did not have to work as salesmen, and went out in the morning to report to the company for tea, making a lot of money. Such a market for sellers is not likely in China’s traditional industry today, and the chain of blocks is likely, though it is a long-term bear market, to create a market for sellers as long as entrepreneurs find an innovative direction where they can find their way. 第六，行业具有明星效应。刘辉谈到了波场的孙宇晨，他表示孙宇晨是他见过区块链行业中赚钱最快的人。为什么他可以这么赚钱呢？因为他是一个网红，是一个明星，转化了大量的韭菜进入到波场生态。他有位台湾朋友做了从17年到18年连续18个月中的区块链创业项目调查，其中有一项指标非常有意思，叫名人效应，如果一个项目由明星代言的话，那么它有着大概率成功。另外一个指标显示，如果一个项目带头人是博士、学者，这样的项目很可能会大比例亏钱。 And sixthly, the industry has a star effect. Liu Xi spoke about Sun Woo-moo at the Playfield, who said that Sun Woo-moo was the fastest-earner in the block chain industry. Why could he make the money? Because he was a net red, a star, transforming a lot of herbs into the wavering ecology. He had a friend in Taiwan who did a survey of sector chain entrepreneurship projects from 17 to 18 years in a row for 18 months, one of which was an interesting indicator, called the celebrity effect, and one that was likely to be successful if a project was presented by a star. Another indicator shows that if a project leader was a doctor, a scholar, such a project would probably be very costly. Ulam项目提出的全新共识算法是怎样的？ What is the new consensus algorithm proposed by the 刘辉表示，区块链行业已经经历了两轮的共识创新，第一轮就是以比特币挖矿为代表的POW挖矿机制。这种机制虽然很稳定的固定了币值，并加强了矿工的挖矿信心，成为了目前区块链世界的最强大共识。但是高耗能、高污染、算力集中能弊端也显现无遗，刘辉谈到目前没有POW矿场是赚钱的。 Liu Hui states that the block chain industry has undergone two rounds of consensus innovation, the first of which is the Pow mining mechanism, which is represented by bitcoin mining. This mechanism, although stable, has fixed its value and strengthened miners’ confidence in mining, has become the strongest consensus in the world of the current block chain. 在ETH提出智能合约概念后，共识创新迎来了第二波，其中比较著名和被比较广泛使用的包括 POS，DPOS，PBFT，以 DAG 为基础的其他共识算法。POS 也需要通过寻找特定哈希值的方式挖矿，但其引入了币龄的概念。从而大大的降低了挖矿的能耗，部分地解决了 pow 的高能耗问题。但是其币龄系统很容易诱发马太效应，引起币的高度集中。过度集中的代币分配，会摧毁整个区块链的经济系统。这是 POS 共识算法所引发的代币集中问题。 Following the introduction of the concept of smart contracts by ETH, consensus innovation has ushered in a second wave, in which the more famous and widely used include POS, POOS, PBFT, and other consensus algorithms based on the DAG. POS also needs to dig mines by looking for specific Hashi values, but it has introduced the concept of currency age. This has significantly reduced the energy consumption of mining and partially solved the high energy consumption of pow. Ulam 共识可以做到超级碎片化节点（任何智能手机、笔记本电脑、pad、手表等智能设备均可以参与挖矿）；完全去中心化（百万级节点）；永不产生比特币一样的算力集中化；49%恶意节点容错（目前所有共识算法中的最大容错率）；TPS可达 10000+，确认时间1s，超低分叉率；可以证明安全共识协议；抗量子攻击。 Ulam Consensus can achieve super-debris nodes (any smart phone, laptop, pad, watch, etc., can be involved in mining); complete decentralisation (millions); never produce the same amount of bitcoin; 49 per cent malign node tolerance (the maximum tolerance rate in all consensus algorithms at present); TPS can reach 10000+, confirmation time 1s, super low fork rates; evidence of security consensus agreements; and resistance to quantum attacks. Ulam公链的挖矿体验在前端是这样的，用户最低支付2000Ulam进入挖矿，持币越多的用户获取幸运数的效率越高。每5秒Ulam公链就会产生1个幸运数，用户的幸运数序列中有该数字就会获得公链的出块奖励，一共22.5Ulam。如果用户获得了幸运数奖励，自身积累的幸运数数列就会被清零重新积累，所以持币时间越多，幸运数序列越广获得奖励的几率也越大。 The mining experience of the Ulam public chain is at the front end, where users pay a minimum of 2,000 Ulam for mining, and the more efficient it is that the more money-bearing users get the lucky number. Every five seconds the Ulam public chain will generate a lucky number, which will be rewarded by a public chain outlet in the user’s lucky number series, amounting to 22.5 Ulam. If the user gets the lucky number reward, the more time the currency is held and the more likely it will be rewarded in the wider series. 这种低能耗、对于硬件没有门槛的创新共识算法在Ulam开放挖矿的前几天中就获得了币圈用户的认可。4月8日Ulam开启挖矿，目前达到1800的日活，币价也在不断的上涨。 This innovative consensus algorithm, which has low energy consumption and no threshold for hardware, was endorsed by currency circle users a few days before Ulam opened mining. Ulam opened mining on 8 April, now reaching 1,800 days, and the price of currency is rising. Ulam项目未来方向与规划 刘辉表示，在Ulam项目启动早期进入挖矿的用户确实拥有红利，因为早期用户少，匹配到随机幸运数的几率就要大一些，如果未来用户增长到一定级别，被抽中幸运数的几率也要低一些。不过他认为，Ulam公链项目的愿景，就是降低区块链挖矿进入的门槛，并降低能耗，做到全民参与挖矿，团队未来的目标是让10亿人参与挖矿。 Liu Hui indicated that users who entered mining early in the start-up of the Ulam project did have dividends, because there were fewer early users, the probability of matching random lucky numbers would be higher, and if future users were to grow to a certain level, the chance of being drawn would be lower. But, in his view, the vision of the Ulam public chain project would be to lower the threshold for digging through blocks and lower energy consumption and to involve the entire population in mining, and the team would aim to involve 1 billion people in mining in the future. Ulam代币的发行总量是额定的，如果未来参与人数太多，奖池的代币不够了怎么办？刘辉表示，目前逻辑设计每5秒出块奖励22.5个Ulam，奖池内的代币还足够不间断挖6年，之后团队会用6年间取得的交易手续费来支撑挖矿，而且未来也有扩容的可能，奖池的问题其实不大。刘辉也表示，10年就是一个时代，如果Ulam能良好的度过10年，团队肯定也会思考出更加适合那个时代的事情。 The total amount of Ulam coins issued is set. If there are too many participants in the future, what if the pool’s tokens are not enough? Liu Hui states that the current logical design offers 22.5 Ulams every five seconds, that there are enough coins in the pool to dig continuously for six years, that the team will use the transaction fees acquired over six years to support mining, and that the future is likely to expand, and that the question of the pool is not a big one. Liu Hui also states that 10 years is an era, and if Ulam survives 10 years, the team will certainly think about something more appropriate for that time. 链茶馆密切关注区块链行业的发展，愿意为优秀的区块链创业项目发声，如果有开发者有宣传推广的需求，可以联系我们。 The kiosks follow closely the development of the block chain industry and are willing to speak out for excellent block chain start-up projects, and can contact us if there is a demand from developers for outreach.
