LBTC-pool.io Explorer Edit descriptionexplorer.lbtc-pool.io Community Progress LBTC featured on NASDAQ billboard in the middle of New York’s Times Square March 16th, LBTC’s propaganda video landed on “the world’s first screen” NASDAQ billboard in New York’s Time Square, sharing LBTC’s resolution with the world! Thousands of people witnessed LBTC showing the world that we are the first DPoS fork in the history. A new Bitcoin experiment is in progress. According to statistics, at least 476 foreign media and websites reported LBTC, including Financial Content, Silicon Investor, The Post & Mail, The Evening Leader, Wallstreet Select,The Atlantic Report, Daily Herald, NewsOk. With more people of extraordinary ability joining in , LBTC is able to develop more fluently, and LBTC’s global influence is expected to further improve. Jack Zhang opened the Twitter account Jack Zhang opened his Twitter account. Welcome to follow our great Lightning Bitcoin inspirator! Twitter interaction is increasing With the raise of popularity, the number of LBTC twitter followers has increased significantly this week, with 450 fans/day on average. Thanks for suggesting us! Spanish Announcement has posted on Bitcointalk At present, we’ve posted four languages of announcement on Bitcointalk. Welcome to leave messages: English ANN Russian ANN Chinese ANN Spanish ANN LBTC Community Interview by Walian March 16th, Jack Zhang was interviewed by Walian on behalf of LBTC. He introduced the characteristics of LBTC, and shared his blockchain investment strategy. “There are many forks now, but how to determine whether a fork has value? First we need to see if it can solve some problem of Bitcoin, or at least try to. It’s more meaningful if they are in line with this point. Due to Bitcoin network congestion, the transaction fees are so high, and the time of arrival is slow, even compared with the traditional payment system such as SWIFT. LBTC has solved these two problems. LBTC uses the DPoS mechanism, thus supports 1,000/tps now, and our goal is to achieve 1,000,000/tps in the future, so it can be used by merchants and customers.” As for investments, I think the first is to invest in valuable projects, second, to invest for the long term. My suggestion to new investors is to invest a little more and a little less. A little more means to invest for a wide range, including technology here and abroad; a little less is to invest every project in a little amount before your own investment logic forms. One can take out 10% of their own mobile assets to try on. Read the article here Jack Zhang made a bet with Kuangren March 19th, Jack Zhang wrote a decleration in his WeChat timeline, which refers to the industry’s well-known market analysis of the self media: Cryptocurrency Trend Kuangren (Maniac). Kuangren published an article at March 18 saying that all Bitcoin forks will turn to zero eventually, and delisted out the drop range. “Most of the altcoins make you lose 60%~80% of assets, and the forks will make this process much sooner.” Unsurprisingly, LBTC is on his list. After seeing the article, Jack wrote a decleration in his WeChat timeline: “if LBTC really returns to zero, and be delisted by exchanges, I’ll give Kuangren 1,000 Bitcoin.” He showed the confidence of LBTC. Read more Interview with Darpal March 20th, Jack gave an interview to Darpal, the founder of the famous blockchain media “Darpal Rating”. The interview covered following topics: Introduction of LBTC team. Is there any breakthrough to solve Bitcoin’s problems? Do LBTC has pre-mine and how much? What do you think about “code hegemony” and “mining hegemony”? Is there a relationship between the core and the company holding the patent right of the Lightning Network? Suppose that in the end lightning network is popularized, will the entire Bitcoin network be completely held by the core? What do you think about Bitmain and Jihan Wu? Why does LBTC use DPoS? Will LBTC adopt smart contract? Besides, he also shared the view of the industry and the prediction of the trend. Here’s the article and the interview video Interview with JGY Interview topic: The dream keeps running, I keep chasing. In the interview, Jack talked about Bitcoin’s past, present and future, can LBTC replace Bitcoin, problems exist in exchanges, how to promote LBTC community. read the article Live broadcast on BiBiNews March 22th, The topic: The Buddhaish investment life of tycoon who got thousand-times return. Jack talked about his investment philosophy, and answered problems from audiences, such as LBTC, different kinds of consensus mechanism, the view of domestic and foreign projects, market analysis, industry celebrities, etc. More than 2.4million audiences have attented.

  6. 在比特币第499,999块分叉的闪电比特币(Lightning Bitcoin,LBTC)凭借颠覆性的DPOS共识机制获得了不少人气,以致于有几个后来的分叉也选择了同一个块高进行分叉,也冒出了一些新的采用DPOS机制的分叉币。看到“闪电比特币”,很多人会在第一时间联想到“闪电网络”(Lightning Network),我们就来普及、对比一下二者,看看谁更“闪电”。 闪电网络的名气已经很大了,Joseph Poon和Thaddeus Dryja在2016年1月发表的论文《The Bitcoin Lightning Network: Scalable Off-Chain Instant Payments》(《比特币闪电网络:可扩展的链下即时支付》),在当时引起巨大反响,而现已率先开始在莱特币上部署。比特币部署闪电网络的前提是“隔离见证”(SegWit)软分叉,目前已经实现,具备这样一个基础,闪电网络的启动仿佛指日可待。 “闪电网络提供了一个可扩展的微支付通道网络。交易双方若在区块链上预先设有支付通道,就可以多次、高频、双向地实现瞬间确认的微支付;双方若无直接的P2P支付通道,只要网络中存在一条连通双方的、由多个支付通道构成的支付路径,闪电网络也可以利用这条支付路径实现资金在双方之间的可靠转移。 闪电网络并不试图解决单次支付的银货对付问题,其假设是单次支付的金额足够小,即使一方违约另一方的损失也非常小,风险可以承受。因此使用时必须注意’微支付’这个前提。” 不得不说,闪电网络是非常聪明的设计,甚至可以说,闪电网络是在不对比特币底层架构进行大规模改动的前提下(比如区块扩容、改变共识机制等)的最佳扩容方案,即使这是一种变相扩容。 然而,很多人在看到了闪电网络的本质后,不仅不支持,反而开始极力反对闪电网络在比特币上的部署。 闪电网络的核心概念,也就是支付渠道(Payment)。使用一些复杂的比特币脚本,双方就可以建立一个“渠道”,这个“渠道”一旦被打开,就可以让他们做成无数笔无需信任的“链下”(Off-chain)交易。为了打开这个渠道,双方需要共同建立一笔交易,交易中的一方或者双方需要将比特币存入这个渠道中,然后这笔交易再被转移到比特币区块链中。当要关闭这个渠道时,双方中的任意一方均有1秒的反应时间,比特币网络的链上交易将替双方支付这次交易所需费用。然而,当这个渠道处于开放状态时,双方在任何时候都可以不通过上链交易就可以共同协商修改支付分配。 按照原有的设计,最终,闪电网络并不会成为白皮书中所讲的“分布式的对等支付层”,而会沦落为银行一样的准集中式的支付网络,最好的情况下,也是以中心辐射型拓扑结构(Hub-and-Spoke Topology)形式结束。 同时,由于支付通道中必须存有充足的资金,也就是说,支付中转站应该给每个渠道存入预存款,而为了实现支付的及时、有效,存款需要达到支付所需额度的10倍左右。即使网络没有受到攻击,沉淀资金的庞大也会带来很严重的资金安全和流通性问题。同时,当人们以不同数额的金额在不同通道中进行买卖时,数值不对称性就很有可能会频繁发生。从一个节点到另一个节点的路径是很容易被找到,但是每一次找到正确数值的跳跃路径则是最困难的部分。如果有超过百分之五十的交易找不到路径,闪电网络实际上会更多促成的是比特币上链交易,而不是在闪电网络上的交易。 无论如何,闪电网络及RSMC、HTLC等技术是先进的、革新的,我们必须为那些为闪电网络作出贡献的开发者点赞。然而,闪电网络作为平行于比特币的区块链,同时又要实现基于比特币协议的智能合约,起点之高必然带来非常复杂的技术问题,而有些问题是不会有完美解决方案的,因为那会触及比特币的本原。 Core团队反对单纯的扩容,矿工不要闪电网络,用户需要权利同时不要拥堵,多方的利益冲突,错不在比特币。比特币发展到今天,是从开始就注定了的结果,一切矛盾的根源在于——POW。 闪电比特币的出现,为比特币提供了一条新的出路,一条从未有人走过的路。DPOS分叉后的比特币,摒弃了矿工的算力竞争(DPOS机制轮流出块),提高了出块速度(3s),还把区块扩容到2M,每秒可处理交易量至少达到1000笔! 再来看看深层的变革——真正去中心化。 如今,比特币的核心权力掌握在算力也就是矿池手里,闪电网络可以为Core或者说Block Stream获得权力和利益,争斗结束,无论哪方胜出,只是改变了用户手续费的归属权,而 并不见比特币网络的根本转好,同时用户依然没有话语权。DPOS机制将权力还给用户,新比特币的发展方向将由用户决定,最终是会保护多数人的利益,而不是如今的比特币只为少数人服务。 如今的比特币储值属性被不断强化,而支付功能在不断衰退,闪电网络只是一种临时止痛的短期解决方案,也可能带来超级节点被监管、取缔的风险,即使这是一个不被Block Stream控制的网络。高难度的技术实现同样也会使用户资产面临安全风险,而归根结底,用户依然承担着高额的支付费用。相较之下,DPOS能够解决的问题实在太多了,一条是看不到未来的路,一条是阳光大道,相信用户会作出正确的选择。 分叉不全是好事,为了比特币的未来变得更好而做的分叉,我们都会支持;那些没有用途,为了分叉而分叉的链,最终都会走向消亡,市场决定一切。
  7. Written by Jordan Kovacs Mining, the bookkeeping of the cryptocurrency world, utilizes different consensus protocols in order to maintain a ledger. Three widely used protocols (or at least, gaining substantial momentum) are Proof-of-Work (PoW), Proof-of-Stake (PoS), and Delegated Proof-of-Stake (DPoS). Proof-of-Work (PoW) Proof-of-Work (PoW) functions are basically what you think it would be. It validates that a certain amount of work happened. Arguably, the most well-known instance of PoW is SHA256 — a hashing algorithm commonly used in digital signatures to verify integrity of data. Bitcoin, the first known cryptocurrency, utilizes PoW to complete transactions on its ledger. PoW functions are designed to be difficult to break in order to prevent malicious types of activity. PoW also allows decentralization in that no single person can gain control over the order of blocks in a ledger. The first miner that solves the block gets a mining reward, however, as more blocks are mined, the mining reward decreases…and will eventually reach zero. Once it reaches that point, miners will only receive transactions fees in exchange for their work. Further, as more blocks are added to a ledger, the difficulty level of the computing needed increases. Mining that uses PoW requires miners to basically break this system in order to solve a math problem. Since this math problem is quite difficult, a ton of computing power is needed. The process also becomes wasteful because all of this computing power only protects the ledger from spammers. Coming up with the computing power needed to solve a transaction that uses PoW is not only time-intensive, but the hardware to do this is expensive as well. Proof-of-Stake (PoS) This brings me to Proof-of-Stake (PoS). PoS is an attempt to mitigate the waste, time, and money that PoW brings to miners. PoS chooses miners in a deterministic way, based upon the miner’s wealth, aka their stake in the matter. There is no block reward, but miners receive transactions fees just like in PoW. In PoS, blocks are not mined, but rather, they are “forged” or “minted. Miners are known as “forgers”. Forgers are required to put their own cryptocurrency units at “stake” (as leverage) in case they validate a fraudulent transaction. This incentivizes forgers to validate correct transactions. Most cryptocurrencies that utilize PoS also give interest to users that stake their coins. The interest is the maximum rate of inflation for a currency’s supply. A notable downfall to PoS is that there is currently no way to handle coins when they are initially given to people. To mitigate this, one can have an ICO and give already-forged coins, or start with a PoW system and then switch to PoS later. A large part of making a PoS system effective is choosing a good way in which forgers are chosen. Two popular methods are: Randomized Block Selection — finds the lowest hash value and the size of of a forger’s stake. Coin Age Based Selection — finds the next forger based on the ‘coin age’ of their stake. Coin age= (# of days the coins have been held as stake) X (# of coins being staked) Some other interesting tidbits: A coin must have been held for at least 30 days before it can be held at stake. Once a forger has forged a block, their coin age becomes zero. They cannot forge another block for 30 days, but will be chosen to forge a new block within the next 90 days (max). These features allow the system to remain decentralized, lowers hardware and electricity costs, and allows a greater number of people to become forgers. A chain split can happen if nodes disagree with each other, just as in the case with the creation of Ethereum Classic. To help mitigate this possibility, the Delegated Byzantine Fault Tolerance (dBFT) was created. Delegated Proof-of-Stake (DPoS) Explaining PoS would not be complete without introducing its new cousin — Delegated Proof of Stake (DPoS). DPoS adds more democratic features to help maintain decentralization. Users vote for witnesses to serve on a panel, of which control transaction sizes, transaction fees, and deterministically choose other witnesses to confirm blocks. “Bad” witnesses can be voted off the panel, and their influence is directly proportional to their stake in the system. PoW Examples Bitcoin (BTC) Ethereum (ETH) — moving towards PoW/PoS then solely PoS Bitcoin Cash (BCH) Litecoin (LTC) Monero (XMR) ZCash (ZEC) DigitalCash (DASH) PoS Examples Cardano (ADA) NEO — technically uses dBFT (NEO) Private Instant Verified TX (PIVX) OkCash (OK) Reddcoin (RDD) DPoS Examples Steemit (STEEM) EOS (EOS) BitShares (BTS) Sources: CryptoCurrencyFacts, HackerNoon, CryptoCompare, Steemit,
