Consensus Mechanism - Snowman++

Testnet will be live soon.

INVAST uses a custom Snowman++ based L1 with the following features:

• Leaderless: No single validator is responsible for block proposals, reducing attack vectors.

• High throughput: Can handle thousands of transactions per second (TPS), with sub-second finality.

• Byzantine Fault Tolerant (BFT): Secure even if up to 1/3 of validators are malicious or offline.

• Finality in under 2 seconds (often under 1 second on performant subnets)

• Validators gossip about transaction acceptance probabilities, updating iteratively until consensus is reached.

This approach enables fast and secure transactions while keeping energy use low. It also prevents centralization and protects against malicious attacks by applying public blockchain security checks, ensuring a fair and reliable system.
