Remora: Scale-out Deterministic Execution for Smart Contracts

Zhengqing Liu, Alberto Sonnino, Igor Zablotchi +2

Modern blockchains rely on a modular architecture that decouples consensus from execution. Recent advances in consensus algorithms have shifted the bottleneck to the execution laye…

Walrus: An Efficient Decentralized Storage Network

George Danezis, Giacomo Giuliari, Eleftherios Kokoris Kogias +4

Decentralized storage faces a fundamental trade-off between replication overhead, recovery efficiency, and security guarantees. Current approaches either rely on full replication,…

Anthemius: Efficient & Modular Block Assembly for Concurrent Execution

Ray Neiheiser, Eleftherios Kokoris-Kogias

Many blockchains such as Ethereum execute all incoming transactions sequentially significantly limiting the potential throughput. A common approach to scale execution is parallel e…

Baxos: Backing off for Robust and Efficient Consensus

Pasindu Tennage, Cristina Basescu, Eleftherios Kokoris Kogias +3

Leader-based consensus algorithms are vulnerable to liveness and performance downgrade attacks. We explore the possibility of replacing leader election in Multi-Paxos with random e…

All You Need is DAG

Idit Keidar, Eleftherios Kokoris-Kogias, Oded Naor +1

We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol that achieves optimal resilience, optimal amortized communication complexity, and optimal time comp…

Brick: Asynchronous Payment Channels

Georgia Avarikioti, Eleftherios Kokoris Kogias, Roger Wattenhofer +1

Off-chain protocols (channels) are a promising solution to the scalability and privacy challenges of blockchain payments. Current proposals, however, require synchrony assumptions…

Enhancing Bitcoin Security and Performance with Strong Consistency via Collective Signing

Eleftherios Kokoris-Kogias, Philipp Jovanovic, Nicolas Gailly +3

While showing great promise, Bitcoin requires users to wait tens of minutes for transactions to commit, and even then, offering only probabilistic guarantees. This paper introduces…
