1. What Is a Consensus Round
A consensus round is a single iteration of a blockchain consensus algorithm during which validators or miners agree on the next block (or set of blocks). It is the atomic unit of agreement in a network.
2. How It Works
In proof-of-stake, each round typically has a designated leader or committee that proposes a block while other validators attest to it; votes are aggregated to finalize. In proof-of-work, a round is the race to solve the puzzle. Different protocols (Tendermint, HotStuff, Avalanche, Algorand) structure rounds differently, affecting finality time, liveness, and resilience to attacks.
3. Why It Matters
Consensus round design determines a chain's speed, finality guarantees, and security. Shorter rounds mean faster blocks but may require more communication; round-based finality (vs probabilistic) changes how users and applications treat settlement certainty. Understanding rounds is key to evaluating chain performance claims.
4. Key Facts
- Tendermint/Cosmos: rounds with proposer + prevotes/precommits
- Avalanche: repeated random subsampling until agreement
- Algorand: pure proof-of-stake with cryptographic sortition
- Finality can be probabilistic (BTC) or immediate (PoS finalizers)
