By adopting DPoS consensus mechanism with 2M blocksize, Lightning Bitcoin improves transaction speed, promotes decentralization and also supports smart contracts. Lightning Bitcoin combines the advantages of Bitcoin and Ethereum and creates a more valuable and functional blockchain system. The ticker of Lightning Bitcoin is LBTC. How to claim LBTC The original bitcoin holders can claim LBTC at a 1:1 ratio if you held BTC in the wallet or the supporting exchanges at Bitcoin block 499,999 (Dec. 18th, 2017). Please only use links provided by this post, website, twitter or official telegram. Why does LBTC use DPoS instead of PoW LBTC employs the DPoS Consensus Mechanism, which implements technological democracies to offset the negative effects of centralization problems posed by the PoW algorithm. As a result, true decentralization can be achieved with the voting right in the hands of the token holders, which ensures to maximize shareholder profitability and the network effect, minimize the costs of maintaining cybersecurity and the cost of operating the network. Significantly reduced the number of participating verification nodes, LBTC can reach the consensus in seconds, and the transaction speed is really FAST as lightning. Features Advantages IoV Protocol Roadmap How to forge LBTC First, one need to download the wallet and register as delegate. One address can register as one delegate. Then you can vote for yourself or ask others to vote for you. The number of votes is the number of LBTC held by the voting address. The top 101 addresses that get the highest number of votes can be regarded as bookkeeping nodes. The ranking and votes can be seen in the block explorer. The previous steps can be completed through the light wallet our the full node wallet, but if you're elected as a bookkeeping node, you need to run the forging process in the full node wallet. The detailed tutorial can be found in LBTC website. Supporting Exchanges ZB.com EXX.com CoinEgg.com BtcTrade.im YoBit.net KKEX.com AEX.com BCEX.ca digifinex.com FAQ 1. LBTC ticker. Lightning Bitcoin ticker is LBTC. You are right if you noticed that some coins have similar ticker or differ only by one letter. Litebitcoin (LBTC, LBTCX) and Bitcoin Lightning (BLT) are coins that are not related to Lightning Bitcoin. Please be careful and check the spelling before any manipulation with cryptocurrencies. 2. How to claim LBTC? How does this airdrop of LBTC work? The original bitcoin holders can claim LBTC at a 1:1 ratio if you held BTC in the wallet or the supporting exchanges at Bitcoin block 499,999. You can find the official wallet and the tutorial on our website. 3. Why price is so different in different exchanges? Some of the exchanges haven't install LBTC wallet yet. This situation should be solved in March. 4. Are there any bounty systems, how can I contribute? Yes! Anyone can contribute by writing articles, setting up promoting groups, or coding. The detailed rules will be posted on Medium in weeks. 5. 3sec + 2MB means the blockchain increases by 40MB/min and 57GB/day? The actual blocksize depends on the transactions during this 3 seconds, and normally it's less than 1KB at the beginning, so 57GB per day is a hypothetical growth with maximum loading. 6. Does LBTC has premine? How do you get the money to work things out? There is no premine, but Lightning Team will build a security node to make sure the network works at earlier stage. The addresses that have no transactions or only inflows less than 1BTC accumulated since Jan 31th 2013 are defined as inactive addresses. We took LBTC from inactive addresses for ecological construction, such as algorithmic research, smart contracts and DApps development, community rewards and global promotion.The wallet will be managed by LBTC foundation. We reserve the rights of these inactive addresses to claim their LBTC back. 7. Are LBTC and Lightning Network related? What's the difference? Lightning Bitcoin is a hard fork of Bitcoin; Lighting Network is an off-chain protocol built on Bitcoin. It is important to underline that these projects are not related to each other. The only thing that Lightning Bitcoin and Lightning Network have in common is the desire to propose solutions to the Bitcoin scalability problem and the word “lightning” . 8. Open source? The Light Wallet is open source: https://github.com/lbtcio, and other code is opened when the main network is stable.

  10. 主板: 主板是电脑中各个部件工作的一个平台,它把电脑的各个部件紧密连接在一起,各个部件通过主板进行数据传输。也就是说,电脑中重要的“交通枢纽”都在主板上,它工作的稳定性影响着整机工作的稳定性。 1、 控制器 控制器负责从存储器中取出指令,并对指令进行译码,并根据指令译码的结果,按指令先后顺序,负责向其它各部件发出控制信号,保证各部件协调一致地完成各种操作。 控制器主要由以下部件组成: ① 程序计数器。存放下一条将要执行的指令在内存中的地址; ② 指令寄存器。保存现在正在执行的指令; ③ 指令译码器。用来识别指令的功能,分析指令的操作要求; ④ 时序部件。产生计算机工作中所需的各种定时控制信号,对各种微操作控制信号进行定时控制。以协调各部件的工作顺序; ⑤ 微操作控制电路。一条指令的执行可以分解为一系列不可再分的微操作命令信号,即微命令,以指挥整个计算机有条不紊地工作。 2、 运算器 运算器是完成算术和逻辑运算的部件,又称算术和逻辑运算单元。计算机所完成的全部运算都是在运算器中进行的。运算器的核心部件是: (1) 运算逻辑部件 (2) 寄存器部件 3、 寄存器 4、 随机读写存储器 RAM:用于存放原始数据、中间结果、最终结果。开机前是空的,断电后数据消失 5、 高速缓冲存储器 Cache是一种高速缓冲存储器,是为了解决CPU与主存之间速度不匹配而采用的一种重要技术。其中片内Cache是集成在CPU芯片中,片外Cache是安插在主板上。高速缓冲存储器的存取速度比主存要快一个数量级,大体与CPU的处理速度相当。 6、 只读存储器 存储的信息只能读出,不能随机改写或存入,断电后信息不会丢失,可靠性高。在主板上的ROM里面固化了一个基本输入/输出系统,称为BIOS(基本输入输出系统)。其主要作用是完成对系统的加电自检、系统中各功能模块的初始化、系统的基本输入/输出的驱动程序及引导操作系统。 7、 硬盘 固态硬盘(SSD 盘,新式硬盘)、机械硬盘(HDD 传统硬盘),SSD采用闪存颗粒来存储,HDD采用磁性碟片来存储 8、 Dos 磁盘操作系统 9、 Linux 多用户、多任务、支持多线程和多CPU的操作系统 10、 Windows 微机操作系统随着微机硬件技术的发展而发展,从简单到复杂。Microsoft公司开发的DOS是一单用户单任务系统,而Windows操作系统则是一多户多任务系统,经过十几年的发展,已从Windows 3.1发展Windows NT、Windows 2000、Windows XP、Windows vista、Windows 7和Windows 8等等。它是当前微机中广泛使用的操作系统之一。Linux是一个源码公开的操作系统,程序员可以根据自己的兴趣和灵感对其进行改变,这让Linux吸收了无数程序员的精华,不断壮大,已被越来越多的用户所采用,是Windows操作系统强有力的竞争对手。 11、 语言处理系统 人和计算机交流信息使用的语言称为计算机语言或称程序设计语言。计算机语言通常分为机器语言、汇编语言和高级语言三类。如果要在计算机上运行高级语言程序就必须配备程序语言翻译程序(下简称翻译程序)。翻译程序本身是一组程序,不同的高级语言都有相应的翻译程序 12、 服务程序 服务程序能够提供一些常用的服务性功能,它们为用户开发程序和使用计算机提供了方便,像微机上经常使用的诊断程序、调试程序、编辑程序均属此类。 13、 计算机硬件系统的性能指标 (1) CPU的主频。主频越高,单位时间内完成的指令数也越多,CPU工作的速度也就越快。 (2) 字长。字长越长,计算机一次所能处理信息的位数就越多,表现为计算机的运算速度越快。 (3) 运算速度。它是一项综合性的性能指标。是指计算机每秒钟执行的指令数,单位是MIPS,即每秒百万条指令。 (4) 内存容量。内存容量越大,一次读入的程序、数据就越多,计算机的运行速度也就越快。 (5) 内存存取速度。内存连续启动两次独立的“读”或“写”操作所需的最短时间,称为存取周期。 (6) I/O速度。I/O的速度是指CPU与外部设备进行数据交换的速度。目前系统性能的瓶颈越来越多地体现在I/O速度上。 14、 信息编码的基本元素是0和1两个数码,称为二进制。 计算机仍采用二进制位数表示信息的原因: 1)物理上容易实现 2)运算规则简单 3)可靠性高 4)易于实现逻辑运算和逻辑判断 二进制和其它进制的转换 十进制转二进制:整数部分除以2取余,直至商为0;小数部分乘以2取整,直至小数部分为0或达到所需精度为止。 十进制转八进制:方法同上。整数部分除以8,小数部分乘以8。 十进制转十六进制:方法同上。整数部分除以16,小数部分乘以16。 15、 计算机中的数据单位 位(bit):计算机存储数据的最小单元(0、1) 字节(Byte):处理数据的基本单位(8bit/Byte) 常用的字节计数单位: 1KB=1024 Byte 1MB=1024 KB 1GB=1024 MB 1TB=1024 GB 1PB=1024 TB 1EB=1024 PB 字长:CPU一次处理数据的二进制位数。64bit 32bit 16、 网络IP地址 为了使计算机相互识别并进行通信,每台连入互联网中的计算机都有一个“号码”,这个“号码”称为该计算机的因特网地址,由于这个地址是在IP协议中定义并由该协议处理的,因此通常称为IP地址。IP协议是TCP/IP协议族中最为核心的协议,它是网络层的协议。在TCP/IP中,IP地址是一个很基本的概念,是理解网络通信的一个重要基础。 Internet接入方式 计算机接入Internet的最基本的方式有三种:通过局域网接入、电话线接入、有线电视电缆接入。另外,还可以通过无线方式接入。 17、 域名系统 域名:为方便记忆而为计算机进行命名。与IP地址作用同,但便于记忆。(通常95%的个人用户入网后由ISP提供一个动态IP地址,没有域名) 域名系统 DNS :完成域名向IP地址的转换。是由若干个域名服务器程序完成的。域名解析就是将域名翻译成IP地址的过程。

    共识机制之一:POW

    共识机制:一个时间段内对事物的前后顺序达成共识的一种算法。 POW Proof of Work(工作量证明) 通过与或运算计算出一个满足规则的随机数(一个符合要求的Block Hash由N个前导零构成,零的个数取决于网络的难度值),即获得本次记账权,发出需要记录的数据后,全网其他节点验证后一起存储。 *与或运算:参加运算的两个数据,按二进制位(除2取余,倒序排列,高位补0)进行“与”运算与“或”运算。“与”运算:当两位同时为1,结果为1,否则为0。“或”运算:参加运算的两位只要其中一个为1,即为1. 在获取随机数的过程中需要大量尝试计算,而在此过过程的时间取决于计算机的速度,取决于算力。 网络中每个节点都提供算力,通过竞争,让最出色的节点获得奖励。可以理解为算力越强,尝试次数越多,越容易得到随机数。 为什么说与中本聪本意相悖? 中本聪提出一CPU一票是节点和算力是平均分布的,随着技术发展:CPU——GPU——FPGA——ASIC矿机,逐渐演变成矿工中心化的局面。 优点:1.去中心化 2. 节点自由进出 3. 算法简单,容易实现 4. 不易破坏 5. 节点间无需交换额外的信息即可达成共识 缺点:1.目前比特币吸引全球大部分算力,影响其他POW的应用获得算力保障自身安全 2. 挖矿带来了资源浪费。 3. 效率较低,每次达成共识需要全网参与共同运算 4. 容易分叉,容错性方面允许全网50%节点出错 5. 永远没有最终性,需检查点机制来弥补最终性(?)

  14. 3月26日,2018全球区块链(杭州)高峰论坛在杭州国际博览中心(G20会馆)隆重举行。本次峰会由杭州市金融办主办,杭州市萧山区金融办、杭州区块链技术与应用联合会、巴比特承办。 杭州市金融办主任王越剑,中国电子技术标准化研究院院长、中国区块链技术和产业发展论坛的理事长赵波,蚂蚁金服区块链技术负责人张辉,中钞区块链技术研究院院长张一锋,巴比特和比原链创始人长铗,普华资本合伙人蒋纯等作主题演讲。 当前区块链处于风口,但千方基金的创始人张银海提醒投资人要注意风险,目前区块链处于非常早期的阶段,可能99%的项目都会死掉。千方基金要做的事情是把这个赛道铺好,更关注底层基础设施的投资机会。 以下是张银海演讲内容,由巴比特整理发布 张银海: 我的演讲题目是《新金融的启蒙与混沌》,希望能把区块链这个事情讲清楚。有一些国家支持区块链,也有一些国家对风险有一定防范,都是可以理解的,因为大家对一件未知的事物,或者一个未知的事物刚刚进入视野的时候每个人都有判断和价值观,区块链就像一个工具一样,最早接触互联网的时候也会碰到一些互联网上有黄赌毒的事情,但是现在好很多了,互联网已经走入千家万户了。 这张图大家可以看一下,这是整个数字资产的规模图,我首先想请问一下大家,什么是数字资产?可能虚拟货币算一个,我之前在金融机构工作,我认为数字资产有三类: 第一,不需要确权的数字资产,比如比特币、以太坊; 第二,智能资产; 第三,金融资产,什么叫做金融资产,金融资产就是资产上链,大家现在在天猫买东西,优衣库在实体店开了一个店,又在天猫上开了一个店,这对于你来说是一样的,比如说美国政府批准一些企业发行债券,区块链发行债券和在纳斯达克或者股权转让系统发行的债券逻辑也是一样的,未来资产上链是一个大趋势,但要合理、合法、合规地去做。 下面我谈四点: 一、区块链产业 我当时在金融机构工作,我看到了国外的一篇论文讲区块链,讲到了1.0、2.0、3.0、4.0,对我影响很深,从挖矿、交易、应用、垄断,是符合它的预测的。区块链每个人都有每个人的理解,我个人认为是这样的,比如说区块链的资产上链的过程和资产证券化是一样的,资产证券化是存款理财化、贷款证券化,资产代币化或者资产上链是一个国家,可以把份额化、证券化资产在链上确权交易,由于区块链不可篡改、全民监督、实时同步的账本,可以少掉很多中介机构,更好监督了,区块链最早的时候是科技金融,为什么叫做科技金融?区块链最早是一个技术,后面会慢慢演变成金融。 最早区块链是底层基础设施,比如说2009年到现在,底层基础设施是一个风口,目前我觉得如果你投资商业模式的话是比较难的,为什么?首先我们来看一下,要有人口才有商业模式,底层基础设施支持才有模式,比如说你在杭州或者在上海一个新的郊区买一套房子,房子周边什么人都没有,有人在那边便利店、开水果店、开美容院,但是两三年以后开什么都活了,因为当时基础设施缺失,现在很多应用层是有意义的,但是目前来说太早了,我们关注底层基础设施。底层基础设施最重要的几点是: 第一,区块链必须要保持不可篡改,能够告诉大家这个是可信区块链,要不然有一个官方认证机构背书,要不然做到完全公有链,像比特币一样。 第二,区块链现在转账手续费必须为0。大家想到没有?以太坊转让手续费、比特币转让手续费都非常高,今天你互联网收发信息需要付费吗?今天用电子邮件转账需要付钱吗?不需要。所以,未来的区块链转账手续率肯定为0。 第三,现在区块链公有链中有一些分叉,但是金融资产上链以后,分叉两条了到底认哪一条就有去中心化的决策治理问题,现在投资区块链项目关注的是,你是否能够解决某种问题或者尝试性的解决某种问题。 我当时接触比特币的时候白皮书是这么说的,比特币是点对点的支付协议,如果从工商银行转账到美国的花旗银行,首先需要2-3天,每笔转账手续费80块钱电报费,可能需要8%左右的手续费,非洲国家更高,我听到最高的是30%的手续费。现在金融机构是靠垄断和信息不对称赚钱,这就违背了金融本意,比如说我来自上海,上海人民广场1000米以内有两家招商银行,可是上海北部一个区,一个区只有两三家,到非洲去可能只有首都有非洲银行,有人评论说想让全世界没有银行的地方使用互联网就可以享受银行服务,这是区块链想做的事情。RTXP协议,这个协议让全世界没有银行的地方只要有互联网就可以使用他们的协议,刚才前面嘉宾提到资产上链,资产上链到底是什么问题?是代码问题还是逻辑问题,还是技术问题?我觉得不是技术问题,本质是一个逻辑问题,比如说跨境转账,今天存到工商银行500元,工商银行给你一个存着写着500,工商银行授权一个IOU,区块链可以干同样的事情,他们就是让全球100多家银行做了一个系统,银行和银行之间可以通过这个协议实时转账做到0手续费,日本、美国加起来100多家银行都在使用这个协议。 大家回想一下,互联网最早的时候大家觉得局域网是未来,一家企业做了U盘,插这个U盘以后可以上网,这家公司获得了风投大量青睐,投资额度很大,后来这家公司死掉了,选择比努力更重要。RTXP也干了这个事情,我也收费,你们银行之间来玩,现在大家都在讲跨链,RTXP跨链技术已经很厉害了,但是大家没有人用,因为不给你用,最早雅虎和163邮箱互相不能发送的,电子邮件实时可以发布,而且雅虎和163可以互相发送,因为有一个SNTP协议,并且不收费。现在区块链和RTXP做了这样一个事情,首先给银行用,银行觉得可以,但是这个逻辑像当年要插一个U盘上网的逻辑一样,不可持续。我们后来放弃了帮助RTXP做推广,帮助另外一个项目进行推广。 二、投资数据 我们认为这个协作像互联网一样应该给所有人免审核的接入,其实我觉得“币”的事情,我认为无非就是一个协议。大家有没有想过,美联储的副主席、德国前副总理都是RTXP的顾问,现在区块链来说目前是比较早期的,我们经常讲信息互联网到价值互联网是一个必然趋势,如果通过某种协议让任意价值和任意价值之间可以直接点对点互相转换,这个协议就是有意义的,如果互相转换你可以选择发送任意价值,对方也可以选择接受的任意价值,比如说你可以选择发送人民币、美金,对方可以选择接受印度的当地货币或者是英镑,这里会用到最优路径选择,比如说直接人民币换美金6.12,但是人民币换成100种货币,会有一个最优选择。 这幅图是区块链投资比较热的领域。这是Coindesk上的项目,大家仔细看这张图的年份,也就是比特币价格跌到最低的时候,区块链领域最大的几个投资正好是在币价跌的最快的时候。 这张图是今年的,投资人慢慢的开始从底层基础设施和底层和应用层开始布局。 这张图非常有意思,比特币的权重,未来可能比特币权重会越来越少。 看一下这张图,目前来说投资领域最靠谱的项目、收益最高的、确定性最高的还是技术类,金融类目前来说比较难,因为金融和强监管的,网络应用、现实应用、娱乐加密货币,我个人推测一下,除了技术类另外大家可以关注的就是物联网类,因为金融是强监管的,物联网类现在因为我当年也投资国民技术,我发现物联网确实底层基础设施缺失。 三、关于我们 第一,千方是一家基金,还有一些孵化器,孵化一些优秀区块链项目,我们和日本一家上市公司成立了一家合资公司,在日本金融厅备案通过,在日本交易所可以上线。 第二,我们投资了一些媒体,因为现在投资项目不赚钱,索性做一些不赚钱的事情,任何一个行业起来,媒体普及类工作肯定是需要。这是我们之前投过的项目,唯链、IOTA、新经、NEO、ARDOR、Lightning Bitcoin、DAF。 四、理念 目前区块链处于非常早期的阶段,我们要做的事情是把这个赛道铺好,纳斯达克最早一批互联网企业基本上都死掉了,但是纳斯达克早期投不到Google和腾讯这样的公司,因为Google和腾讯没有出来,所以我们要不断学习、不断提高自己的认知,还要分散投资、长线投资。 目前区块链是风口,但是还有一些风险,这些风险大家可以注意,99%的项目都会死掉,提醒大家一下。 本文作者 邱祥宇
  15. Lightning Bitcoin What is Lightning Bitcoin Lightning Bitcoin is a fork of the Bitcoin blockchain. By adopting DPoS consensus mechanism with 2M blocksize, Lightning Bitcoin improves transaction speed, promotes decentralisation and also supports smart contracts. Lightning Bitcoin combines the advantages of Bitcoin and Ethereum and creates a more valuable and functional blockchain system. How to claim LBTC The original bitcoin holders can claim LBTC at a 1:1 ratio if you held BTC in the wallet or the supporting exchanges at Bitcoin block 499,999 (Dec. 18th, 2017). Please only use links provided from the official resources! Why does LBTC use DPoS instead of PoW LBTC employs the DPoS Consensus Mechanism, which implements technological democracies to offset the negative effects of centralisation problems posed by the PoW algorithm. As a result, true decentralisation can be achieved with the voting right in the hands of the token holders, which ensures to maximise shareholder profitability and the network effect, minimise the costs of maintaining cybersecurity and the cost of operating the network. Significantly reduced the number of participating verification nodes, LBTC can reach the consensus in seconds, and the transaction speed is really FAST as lightning. Features 3 sec block interval| adjusting block size | forging with CPU | up to 24 million transactions per day Advantages Community Autonomous Rapidity Fair Distribution Smart Contracts & DApp IoV Protocol Internet of Value Roadmap Roadmap How to forge LBTC How to forge (mine) LBTC? First, one need to download the wallet and register as delegate. One address can register as one delegate. Then you can vote for yourself or ask others to vote for you. The number of votes is the number of LBTC held by the voting address. The top 101 addresses that get the highest number of votes can be regarded as bookkeeping nodes. The ranking and votes can be seen in the block explorer. The previous steps can be completed through the light wallet our the full node wallet, but if you’re elected as a bookkeeping node, you need to run the forging process in the full node wallet. The detailed tutorial can be found in LBTC website.
