As a promising technology, blockchain has found widespread application in numerous
decentralized systems. However, the scalability problem of blockchain has drawn …

The Paxos algorithm is famously difficult to reason about and even more so to implement,
despite having been synonymous with distributed consensus for over a decade. The …

Current leader-based Byzantine fault-tolerant (BFT) protocols aim to improve the efficiency
for achieving consensus while tolerating failures; however, Byzantine servers are able to …

The software ecosystem is a trust-rich part of the world. Collaboratively, software engineers
trust major hubs in the ecosystem, such as package managers, repository services, and …
