ACeD: Scalable Data Availability Oracle
Peiyao Sheng, Bowen Xue, Sreeram Kannan +1
A popular method in practice offloads computation and storage in blockchains by relying on committing only hashes of off-chain data into the blockchain. This mechanism is acknowled…
Blockchain CAP Theorem Allows User-Dependent Adaptivity and Finality
Suryanarayana Sankagiri, Xuechao Wang, Sreeram Kannan +1
Longest-chain blockchain protocols, such as Bitcoin, guarantee liveness even when the number of actively participating users is variable, i.e., they are adaptive. However, they are…
BFT Protocol Forensics
Peiyao Sheng, Gerui Wang, Kartik Nayak +2
Byzantine fault-tolerant (BFT) protocols allow a group of replicas to come to a consensus even when some of the replicas are Byzantine faulty. There exist multiple BFT protocols to…
Free2Shard: Adaptive-adversary-resistant sharding via Dynamic Self Allocation
Ranvir Rana, Sreeram Kannan, David Tse +1
Propelled by the growth of large-scale blockchain deployments, much recent progress has been made in designing sharding protocols that achieve throughput scaling linearly in the nu…
Everything is a Race and Nakamoto Always Wins
Amir Dembo, Sreeram Kannan, Ertem Nusret Tas +4
Nakamoto invented the longest chain protocol, and claimed its security by analyzing the private double-spend attack, a race between the adversary and the honest nodes to grow a lon…
