The core technical component of blockchains is consensus: how to reach agreement among
a distributed network of nodes. A plethora of blockchain consensus protocols have been …

Despite recent progresses of practical asynchronous Byzantine-fault tolerant (BFT)
consensus, the state-of-the-art designs still suffer from suboptimal performance. Particularly …

Recently, blockchain has emerged as a peer-to-peer (P2P) immutable distributed ledger
technology-based network, and its consensus mechanism is playing an important role in …

Partially synchronous Byzantine consensus protocols typically structure their execution into
a sequence of views, each with a designated leader process. The key to guaranteeing …

An urgent demand of deploying BFT consensus (eg, atomic broadcast) over the Internet is
raised for implementing (permissioned) blockchain services. The deterministic synchronous …

Tendermint is the replication engine at the core of Cosmos, a network of proof-of-stake
blockchains. In the lifespan of blockchains, Cosmos and Tendermint are mature …

In this paper we analyze Tendermint, proposed in 12, one of the most popular blockchains
based on PBFT Consensus. Our methodology consists in identifying the algorithmic …

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 …

Over the past years, blockchain technology has become more and more interesting since its
ability to carry out transactions without any mediator. To ensure the transactions' reliability …

Byzantine state-machine replication (SMR) ensures the consistency of replicated state in the
presence of malicious replicas and lies at the heart of the modern blockchain technology …
