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 6天前
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 1个月前 (02-04)

BlockSDN-VC: 基于SDN与虚拟坐标的高性能区块链交易广播框架 BlockSDN-VC 是一个面向高性能区块链的创新型交易广播框架。它针对传统区块链(如比特币、以太坊)中基于Gossip协议的交易广播机制所形成的性能瓶颈,提出了一种根本性的解决方案。该框架的核心思想是将虚拟坐标系统的计算从不可靠、易受攻击的P2P节点层“提升”至拥有全局网络... 中文社区管理员 4个月前 (11-06)
