Bitcoin-IPC: Scaling Bitcoin with a Network of Proof-of-Stake Subnets
Marko VukoliÄ, Orestis Alpos, Jakov Mitrovski +3
This paper introduces Bitcoin-IPC, a protocol that scales Bitcoin through a network of permissionless, interconnected, programmable Proof-of-Stake (PoS) Layer-2 chains, called subn…
Pod: An Optimal-Latency, Censorship-Free, and Accountable Generalized Consensus Layer
Orestis Alpos, Bernardo David, Jakov Mitrovski +2
This work addresses the inherent issues of high latency in blockchains and low scalability in traditional consensus protocols. We present pod, a novel notion of consensus whose fir…
An overview of the efficiency and censorship-resistance guarantees of widely-used consensus protocols
Orestis Alpos, Bernardo David, Nikolas Kamarinakis +1
Censorship resistance with short-term inclusion guarantees is an important feature of decentralized systems, missing from many state-of-the-art and even deployed consensus protocol…
Consensus Under Adversary Majority Done Right
Srivatsan Sridhar, Ertem Nusret Tas, Joachim Neu +2
A specter is haunting consensus protocols--the specter of adversary majority. Dolev and Strong in 1983 showed an early possibility for up to 99% adversaries. Yet, other works show…
Light Clients for Lazy Blockchains
Ertem Nusret Tas, David Tse, Lei Yang +1
Lazy blockchains decouple consensus from transaction verification and execution to increase throughput. Although they can contain invalid transactions (e.g., double spends) as a re…
