The Octopus Network is a multichain cryptonetwork for launching and running Web3.0 application-specific blockchains — appchains. Appchains in the Octopus Network benefit from flexible and cost-effective leased security (LPoS), out-of-the-box multichain interoperability, complete infrastructure, and a ready-to-be-engaged community. The core of the Octopus Network is the Octopus Relay — a set of smart contracts running on the NEAR blockchain, aka mainchain, that implements the security leasing market.
