Unconditionally Safe Light Client
Niusha Moshrefi, Peiyao Sheng, Soubhik Deb +2
Blockchain applications often rely on lightweight clients to access and verify on-chain data efficiently without the need to run a resource-intensive full node. These light clients…
Babylon: Reusing Bitcoin Mining to Enhance Proof-of-Stake Security
Ertem Nusret Tas, David Tse, Fisher Yu +1
Bitcoin is the most secure blockchain in the world, supported by the immense hash power of its Proof-of-Work miners, but consumes huge amount of energy. Proof-of-Stake chains are e…
Securing Parallel-chain Protocols under Variable Mining Power
Xuechao Wang, Viswa Virinchi Muppirala, Lei Yang +2
Several emerging PoW blockchain protocols rely on a "parallel-chain" architecture for scaling, where instead of a single chain, multiple chains are run in parallel and aggregated.…
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…
PoSAT: Proof-of-Work Availability and Unpredictability, without the Work
Soubhik Deb, Sreeram Kannan, David Tse
An important feature of Proof-of-Work (PoW) blockchains is full dynamic availability, allowing miners to go online and offline while requiring only 50% of the online miners to be h…
