3 月 26 日，据 CoinDesk 报道，加密初创公司 Plasma 近日公布了其稳定币专用区块链的技术特性，该链采用“HotStuff 启发”的共识机制，承诺实现快速高效的全球稳定币转账。
HotStuff 共识是一种拜占庭容错 (BFT) 机制，即使部分节点出现故障或恶意行为，系统仍能达成共识。与传统 BFT 系统中每个节点需要多次来回确认不同，HotStuff 机制简化了这一过程，由领导节点提出决策，验证节点一步确认，同时允许在领导节点行为异常时无缝替换，从而减少延迟并提高效率。
Plasma 在社交媒体 X 上宣布：“Plasma 核心采用 PlasmaBFT，这是一种基于 Fast HotStuff 的共识协议，针对快速最终性和低延迟进行了优化，支持高频全球稳定币转账。”
据悉，Plasma 区块链专为市值 1440 亿美元的全球最大美元稳定币 Tether 设计，该稳定币占据稳定币市场 60% 以上份额，其发行方去年盈利 137 亿美元。项目早期支持者包括风险投资家 Peter Thiel、Tether CEO Paolo Ardoino 和 Split Capital 的 Zaheer Ebtikar。
