Octopus Network is a brand new multichain network born to serve application-specific blockchains, aka Appchain. Octopus Network provides flexible and affordable leased security, out-of-box cross-chain interoperability, one-stop infrastructure, and a ready-to-be-engaged community for the appchains.Octopus RelayOctopus Relay is the core of the Octopus Network — a set of smart contracts (opens new window)running on the NEAR blockchain, aka mainchain, that implements the security leasing market.AppchainAn Octopus Appchain is a Substrate-based blockchain that is made for a specific decentralized application. Once integrating the pallet pallet-octopus-appchain (opens new window), the Appchain will be geared up to anchor off the Octopus Network.ValidatorIn the Octopus Network, OCT holders can stake OCTs to become validators or delegators. Validators secure Appchains by staking OCT and running the validator nodes of the Appchain. Delegators secure Appchains by delegating the OCT they stake to honest validators.
