使用延迟塔去中心化许可区块链
Decentralizing Permissioned Blockchain with Delay Towers
摘要：
人们对无许可区块链的兴趣越来越大，这揭示了其潜在的可扩展性问题。许可型区块链提供高交易吞吐量和低延迟，同时损害去中心化。在寻求一个分散的，可扩展的区块链结构，即，为了在无许可的环境中提供许可区块链的可扩展性，我们提出了L4 L，以鼓励在许可的Libra网络上进行去中心化，而不影响其可持续性。L4 L采用延迟塔，--利用可验证延迟功能的拼图塔--用于在无许可设置中建立身份。延迟塔由于其顺序执行而无法并行化，使其成为生态友好的替代品。我们还讨论了替换参与共识的验证器以促进合规行为的方法。我们的评估发现，在许可网络上实现去中心化的成本几乎可以忽略不计。此外，延迟塔为现有的无许可共识机制提供了一种替代方案，而无需空投或预售代币。
英文摘要：
Growing excitement around permissionless blockchains is uncovering its latent scalability concerns. Permissioned blockchains offer high transactional throughput and low latencies while compromising decentralization. In the quest for a decentralized, scalable blockchain fabric, i.e., to offer the scalability of permissioned blockchain in a permissionless setting, we present L4L to encourage decentralization over the permissioned Libra network without compromising its sustainability. L4L employs delay towers, -- puzzle towers that leverage verifiable delay functions -- for establishing identity in a permissionless setting. Delay towers cannot be parallelized due to their sequential execution, making them an eco-friendly alternative. We also discuss methodologies to replace validators participating in consensus to promote compliant behavior. Our evaluations found that the cost of enabling decentralization over permissioned networks is almost negligible. Furthermore, delay towers offer an alternative to existing permissionless consensus mechanisms without requiring airdrops or pre-sale of tokens.
