2.14 Whisper和Swarm

Whisper和Swarm分别是去中心化的通信协议和存储平台,它们都由以太坊开发人员开发的。Whisper是一个去中心化的通信协议,Swarm则是一个去中心化的文件系统。
Whisper允许网络中的节点彼此通信。它支持广播、用户到用户、加密信息等,但不用于传输大数据。想更深入学习Whisper,请访问https://github.com/ethereum/wiki/wiki/Whisper
,在https://github.com/ethereum/wiki/wiki/Whisper-Overview
可以看到代码示例概述。
Swarm类似于Filecoin,二者最大的区别是技术细节和激励机制。Filecoin不惩罚存储;而Swarm
惩罚存储。因此,这进一步提高了文件可用性。那么,Swarm中的激励机制如何工作?它有内部货币吗?事实上,Swarm没有内部货币,而是用以太币进行
激励。在以太坊中有智能合约,智能合约记录激励情况。显然,智能合约不能与Swarm通信,但Swarm能与智能合约通信。所以用户基本上通过智能合约向
存储付款,该支付在失效后被释放给存储。用户还可以向智能合约报失文件,在此情况下它可以惩罚存储。可以访问https://github.com/ethersphere/go-ethereum/wiki/IPFS-&-SWARM
了解Swarm和IPFS/Filecoin之间的区别,访问https://github.com/ethersphere/go-ethereum/blob/bzz-config/bzz/bzzcontract/swarm.sol
查看智能合约代码。
在写本书时,Whisper和Swarm仍处于开发阶段,许多事情仍不明确。
