摘要:

在大数据区块链时代,存储可扩展性至关重要。一种存储可扩展的区块链可以将状态存储扩展到任意数量的节点,减少每个节点的存储压力,类似于分布式数据库。先前的研究广泛使用分片技术来实现存储可扩展性;然而,这些方法不可避免地会牺牲安全性和活锁保证。在本文中,我们提出了一种新的状态执行解耦架构,以及Supermassive Blockchain,一种新的存储可扩展的拜占庭容错(BFT)协议,能够维持传统BFT协议的确定性安全属性。状态管理系统采用擦除编码确保状态可用性,同时具有可扩展的存储消耗,而全局共识和执行层保持稳健的安全特性。我们的评估表明,Supermassive Blockchain在比先前方法更优的存储可扩展性的同时,带来了较低的网络开销。

英文摘要:

Storage scalability is paramount in the era of big data blockchain. A storage-scalable blockchain can effectively scale out state storage to an arbitrary number of nodes and reduce the storage pressure on each, similar to distributed databases. Prior research has extensively utilized sharding techniques to attain storage scalability; however, these approaches invariably compromise safety and liveness guarantees. In this work, we propose a novel state-execution decoupled architecture, and Supermassive Blockchain, a novel storage-scalable Byzantine fault tolerance (BFT) protocol that can sustain the deterministic security properties of conventional BFT protocols. The state management system employs erasure coding to ensure state availability with scalable storage consumption, while the global consensus and execution layers maintain robust security characteristics. Our evaluation indicates that Supermassive Blockchain achieves better storage scalability compared to prior approaches while incurring low network overhead.
