论文摘要
围绕无许可区块链的兴奋正在发现其潜在的可伸缩性问题。许可的区块链提供高的交易吞吐量和低延迟，同时损害分散性。为了寻求分散的，可扩展的区块链结构，即在无许可的环境中提供许可区块链的可扩展性，我们提出L4L，以鼓励通过允许的天秤座网络分散的情况下，而不会损害其可持续性。 L4L采用延迟塔， - 利用可验证的延迟功能的拼图塔 - 在无许可环境中建立身份。由于其连续执行，延迟塔无法并行化，这使其成为环保的替代方案。我们还讨论了取代参与共识以促进合规行为的验证者的方法。我们的评估发现，实现权力与权限网络的权力化成本几乎可以忽略不计。此外，延迟塔提供了无许可共识机制的替代方案，而无需飞机或代币预售。
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.
