List of L2 companies in Web3 (2026)

Hyperbridge Parachain is a Polkadot parachain operating with ParaId 3367 and chainId 'nexus' on mainnet. Block candidates are produced by collators and submitted with proofs to Polkadot relay chain validators, which re-execute state transitions to confirm correctness. Finality is inherited from the Polkadot relay chain through this validation process. Each collator additionally runs an in-node fisherman task that monitors connected L2 state across multiple independent RPC providers, submitting a veto when providers disagree on L2 state before Hyperbridge commits to that height. Collator selection is determined by a reputation asset accumulated through prior relayer and prover contributions, with each authored block rewarding the collator 0.7 BRIDGE from the network treasury.
