揭秘区块链高级玩法–跨链的魔法

背景从2009年本聪大叔发明了比特币开始,区块链逐渐进入人们的视野,于是我们逐渐认识到竟然还可以有一种脑洞清奇的记账方式是去中心化的。慢慢的,人们很自然地发现这套账本协议不仅能用在支付领域,还能进一步扩展来搭建其他领域的各种应用。所以6年后一个俄罗斯的90后发明了一个叫以太坊的东西,让人们可以随心所欲地在区块链上搭建不同的去中心化应用(DApp)。如果把比特币当作区块链1.0,以太坊是2.0,我们就可以发现从1.0到2.0就是从“钱包”到“苹果商城”的跨越。可即便是有了“苹果商城”,上面的应用也是寥寥无几,普罗大众更是无人问津,似乎区块链是一种亚文化现象,总是处于不温不火的状态。直到以太坊上线的两年后,比特币价格一飞冲天,超越了千亿美金的市值,人们才认识到区块链巨大的商业价值。 于是功能各异的区块链层出不穷,市面上比较主流的就起码有30多种。可问题是这些主权链之间是无法相互通信的,因为它们各自使用了迥然不同的协议。就好比鸡同鸭讲,注定是无法交流的。那能不能在区块链2.0的基础之上设计一套更加通用的协议,从而能无缝衔接各种区块链?波卡(Polkadot)就是为此而生的。 ...

VCash Report

VCashVCash combines the characteristics of Bitcoin with Mimblewimble technology. It inherits Bitcoin’s distribution mechanism and leverages on Grin’s privacy protocol by using Mimblewimble implementation.VCash adopts Merged Mining to allow mining of VCash and Bitcoin simultaneously with the same ‘Proof-of-Work’ (POW) algorithm. Blockchains that utilize the POW algorithm are susceptible to the risk of a 51% attack on the network. However, Bitcoin has the largest number of miners worldwide and widely distributed hashing power, which significantly lowers the risk of a 51% attack. With Merged Mining, VCash is able to leverage on Bitcoin’s hashing power with the support from Bitcoin mining pools. Therefore, VCash possesses the same level of security as Bitcoin and launching a 5...

Libra Starts the End of Public Chains

In my previous article (So Many Public Chains, So Few Dapps), I pointed it out that too many public chains was one of the reasons that there were so few Dapps. App developers really do not want to develop their apps for so many blockchains. The over supply of blockchains is actually hindering the adoption of blockchain technology. The Libra blockchain provides an opportunity to solve this problem. Libra is composed of three parts, Libra stablecoin, Libra blockchain, and Libra Association. Currently, most attentions have been focused on Libra stablecoin. But, in my opinion, Libra stablecoin is just a Troy horse. The real threat hidden in Libra is Libra blockchain. According Libra whitepaper, Libra provides a simple financial market infrastructure. But Libra blockchain does not only...
