FAQ

How is a Polygon supernet different from an Avalanche subnet?

Subnets and Supernets are both scalability solutions for building L1 blockchains quickly. Avalanche uses the Snowman Proof-of-Stake consensus protocol for probabilistic consensus and infinite decentralization, while Polygon’s IBFT consensus protocol guarantees consensus but limits permissionless participation and decentralization. Avalanche processes up to 4500 TPS, while Polygon processes up to 1500 TPS.

Subnets have around 1,300 validators, require a minimum staking amount of 2000 AVAX to become a validator and require all validators to validate the entire primary network. Supernets have 100 validators, need a minimum staking amount of 20,000 MATIC to become a validator, and do not have a similar validation requirement. Supernets and subnets also differ in their approach to Slashing, with Avalanche aiming to prevent centralization of staking while Ethereum favors higher stake validators.
