From Byzantine Replication to Blockchain: Consensus is only the Beginning
Alysson Bessani, Eduardo Alchieri, João Sousa +2
The popularization of blockchains leads to a resurgence of interest in Byzantine Fault-Tolerant (BFT) state machine replication protocols. However, much of the work on this topic f…
Smart Contracts on the Move
Enrique Fynn, Alysson Bessani, Fernando Pedone
Blockchain systems have received much attention and promise to revolutionize many services. Yet, despite their popularity, current blockchain systems exist in isolation, that is, t…
Partitioned Paxos via the Network Data Plane
Huynh Tu Dang, Pietro Bressana, Han Wang +6
Consensus protocols are the foundation for building fault-tolerant, distributed systems, and services. They are also widely acknowledged as performance bottlenecks. Several recent…
Early Scheduling in Parallel State Machine Replication
Eduardo Alchieri, Fernando Dotti, Fernando Pedone
State machine replication is standard approach to fault tolerance. One of the key assumptions of state machine replication is that replicas must execute operations deterministicall…
Challenges and pitfalls of partitioning blockchains
Enrique Fynn, Fernando Pedone
Blockchain has received much attention in recent years. This immense popularity has raised a number of concerns, scalability of blockchain systems being a common one. In this paper…
Network Hardware-Accelerated Consensus
Huynh Tu Dang, Pietro Bressana, Han Wang +5
Consensus protocols are the foundation for building many fault-tolerant distributed systems and services. This paper posits that there are significant performance benefits to be ga…
