Modeling Resources in Permissionless Longest-chain Total-order Broadcast
Sarah Azouvi, Christian Cachin, Duc V. Le +2
Blockchain protocols implement total-order broadcast in a permissionless setting, where processes can freely join and leave. In such a setting, to safeguard against Sybil attacks,…
State-Machine Replication Scalability Made Simple (Extended Version)
Chrysoula Stathakopoulou, Matej Pavlovic, Marko Vukolić
Consensus, state-machine replication (SMR) and total order broadcast (TOB) protocols are notorious for being poorly scalable with the number of participating nodes. Despite the rec…
Multi-Shard Private Transactions for Permissioned Blockchains
Elli Androulaki, Angelo De Caro, Kaoutar Elkhiyaoui +3
Traditionally, blockchain systems involve sharing transaction information across all blockchain network participants. Clearly, this introduces barriers to the adoption of the techn…
On the Interoperability of Decentralized Exposure Notification Systems
Marko Vukolic
This report summarizes the requirements and proposes a high-level solution for interoperability across recently proposed COVID-19 exposure notification efforts. Our focus is on int…
Can 100 Machines Agree?
Rachid Guerraoui, Jad Hamza, Dragos-Adrian Seredinschi +1
Agreement protocols have been typically deployed at small scale, e.g., using three to five machines. This is because these protocols seem to suffer from a sharp performance decay.…
Mir-BFT: High-Throughput Robust BFT for Decentralized Networks
Chrysoula Stathakopoulou, Tudor David, Matej Pavlovic +1
This paper presents Mir-BFT, a robust Byzantine fault-tolerant (BFT) total order broadcast protocol aimed at maximizing throughput on wide-area networks (WANs), targeting deploymen…
