ChainIDE #6 跨链如何实现区块链价值

讨论背景

在区块链技术发展的过程中，网络孤立性阻碍了不同区块链之间的协同操作，于是跨链技术应运而生，跨链实际上实现了数据在链与链之间的流通。
区块链是一种分布式账本，每条区块链都是一个独立的账本，数据在账本与账本之间并不会流通，但我们可以从用户的角度去理解，用户存储在一条区块链上的数据，能够变成另一条链上的数据，这样就实现了数据的流通。更通俗一点，可以理解为人民币与美元的兑换。

常见的跨链技术：

公证人机制：公证人作为可信第三方，不同账本可以通过第三方直接传输数据。

侧链/中继：A为主链，B为侧链，A可以不知道B，但是B一定要知道A，C链可以读到所有链，整个过程就是“A-C-B”。当一条侧链链接了很多条主链时，它就变成了一条中继链。

哈希锁定：在一定时间段内在A和B之间通过押金锁定的方式创建一个支付通道。

另一种将其他链上资产跨链到自身公链的方式就是去中心化跨链资产桥，跨链桥可以将代币或数据在区块链之间转移。

跨链桥的类型：

托管+中心化（中心化交易所跨链、WBTC等）

托管+PoA（权威证明）

托管+PoS（权益证明）（Matic、xDAI）

托管+MPC（多方计算）（Thorchain、AnySwap）

非托管+MPC（Multichain）

其中，WBTC是一种基于以太坊、与比特币挂钩的ERC20代币，也就是说WBTC可以将BTC从bitcoin跨到ethereum，让人们在ETH链上也能交易BTC。

Omni Consumer Protocols（OCP）可以实现在ETH和BSC之间的加密资产双向跨链。
