## Octopus Network

Fusotao uses the paradigm of *“execute off-chain, verify on-chain”*. We have a centralized service off-chain to store the order book and match the trading order. After the off-chain matching, the protocol will verify it on-chain. That means the assets are always in the user’s control and always on-chain. In addition, Fusotao will collaborate with Octopus Network to ensure blockchain security and enable Fusotao’s interoperability with NEAR or any IBC-enabled blockchain.
