熊市补课系列之 Harmony @harmonyprotocol

19年5月,Harmony 在币安 IEO。Harmony 是一个基于状态分片和 PoS 的高性能公链项目。
如何工作:随机状态分片

通过使用随机状态分片,将节点随机分配给分片,多个分片允许并行处理能力和更快地在区块链上创建块。TPS 可以达到 2000,而BTC和ETH分别只有 5 TPS 和 13 TPS。
需要说明几个概念:
- “随机”保证安全性:例如,总共有200个验证节点,10个分片,每个分片会分到20个节点,显然安全性降低了。节点随机分配给每个分片,导致作恶节点很难集中到某个分片上,从而提高作恶难度。
- “状态分片”:每组分片分别存储一部分账本信息,而不是存储全网所有账本。
如何工作:FBFT+Pos共识

Harmony采用的是FBFT+PoS的共识机制,FBFT是快速拜占庭容错协议。Harmony对Zilliqa的PBFT做了改进,PBFT每次通讯都要向所有节点广播,节点越多,通讯复杂度以指数级别上升。而FBFT运行一个多签过程来收集验证节点的投票。
FBFT可使超过 250 个节点在 2 秒内达成共识
Harmony CEO叫谢镇滔,中国人,据说是个神童。团队其他成员也都来自 Google、微软等互联网巨头。

「30天复盘100个NFT项目」
熊市就该多学少动,我决定30天复盘100个NFT项目,总结规律,为下个牛市做准备。
期间我不会分享全部100个项目,但会把有价值的分享出来。最后,我会写一个长文做总结,并把100个项目的笔记和总结一并分享出来。
