Bitcoin is the first fully decentralized permissionless blockchain protocol and achieves a high level of security: the ledger it maintains has guaranteed liveness and consistency properties as long as the adversary has less compute power than the honest nodes. However, its throughput is only 7 transactions per second and the confirmation latency can be up to hours. Prism is a new blockchain protocol which is designed to achieve a natural scaling of Bitcoin's performance while maintaining its full security guarantees. We present an implementation of Prism which achieves a throughput of 70,000 transactions per second and confirmation latencies of tens of seconds.

Prism：将比特币扩大 10,000 倍

比特币是第一个完全去中心化的无需许可的区块链协议，并实现了高度的安全性：只要对手的计算能力低于诚实节点，它所维护的分类账就可以保证活跃性和一致性。但是，其吞吐量仅为每秒 7 笔交易，确认延迟可能长达数小时。Prism 是一种新的区块链协议，旨在实现比特币性能的自然扩展，同时保持其完整的安全保证。我们展示了 Prism 的实现，它实现了每秒 70,000 笔交易的吞吐量和数十秒的确认延迟。
