The last fifteen years have seen an impressive amount of work on protocols for Byzantine
fault-tolerant (BFT) state machine replication (SMR). However, there is still a need for …

State machine replication (SMR) uses Paxos to enforce the same inputs for a program (eg,
Redis) replicated on a number of hosts, tolerating various types of failures. Unfortunately …

Resilience is vital to blockchain systems and helps them automatically adapt and continue
providing their service when adverse situations occur, eg, node crashing and data …

A long-standing promise of Byzantine Fault-Tolerant (BFT) replication is to maintain the
service correctness despite the presence of malicious failures. The key challenge here is …

Incorporating resilience in design is important for the long-term viability of complex
engineered systems. Complex aerospace systems, for example, must ensure safety in the …

Byzantine fault-tolerant algorithms promise agreement on a correct value, even if a subset of
processes can deviate from the algorithm arbitrarily. While these algorithms provide strong …

We present Byzantine Fault-Avoidance (BFA), a fault-resilient architecture designed for
Byzantine Fault Tolerant (BFT) systems to withstand against attacks and failures. BFA allows …

The increasing level of sophistication of cyber attacks which are employing cross-cutting
strategies that leverage multi-domain attack surfaces, including but not limited to, software …

While the potential applications of consortium blockchain are becoming increasingly
evident, the fault tolerance of systems in the complex and changeable real environment has …

The last fifteen years has seen an impressive amount of work on protocols for Byzantine fault-
tolerant (BFT) state machine replication. However, there is still a lack of practical and reliable …
