Fast-HotStuff: A Fast and Robust BFT Protocol for Blockchains 在区块链系统中,共识协议决定了整个网络的性能、安全性和扩展能力。近年来,HotStuff 被认为是拜占庭容错(BFT)共识领域的重要突破,并被 Facebook 的 DiemBFT、Flow 等区块链系统采用。然而,尽管 HotStuff 在设计上非常优雅,它仍然存在一些性能上... 韦帆 4周前 (03-13)
Algorand: Scaling Byzantine Agreements for Cryptocurrencies 一、传统区块链为什么慢? 比特币采用 PoW(Proof of Work)工作量证明。 这种机制通过算力竞争决定谁生成新区块,同时依赖“最长链规则”解决冲突。 但它存在两个问题: 1、 分叉不可避免 多个矿工可能同时挖出区块,导致区块链短暂分叉。 ... 韦帆 1个月前 (03-05)
ByShard: Sharding in a Byzantine Environment 传统区块链系统往往选择: 全量复制(所有节点存全部数据) 每笔交易全网共识 结果是:安全有了,但吞吐量惨不忍睹 一旦数据量或交易规模上来,系统直接“卡死”。 那有没有可能: 既能分片扩容,又能抗拜占庭攻击,还能支持数据库级事务? B... 韦帆 2个月前 (02-04)
