# Consensus Mechanism

Ottochain utilises a consensus mechanism that ensures the security and integrity of the network. The Octopus 2.0 Interchain Security mechanism named NEAR restaking is integrated through contracts maintained by Octopus Network, while Ottochain itself utilises the CometBFT consensus forked from the original consensus of Cosmos known as Tendermint. Ottochain validators stake tokens as collateral (Proof of Stake) to generate blocks while NEAR tokens are staked to the Octopus Network contracts to extend economic security beyond the Ottochain PoS. This consensus mechanism guarantees the immutability and finality of transactions on Ottochain, but also supports native interoperability with NEAR Protocol.
