About Hive-Engine
Hive Engine is a smart contracts side-chain platform for the Hive blockchain. This means that it can execute custom smart contracts based on data published to the Hive blockchain. This allows us to do things such as creating custom tokens, diesel swap pools, marketplace, NFTs or literally anything else achievable with a smart contract.
Hive Engine uses the Hive Smart Contracts software created by @harpagon. (https://github.com/hive-engine/steemsmartcontracts-wiki) The software scans all blocks added to the Hive blockchain for transfers, custom_json, or even comment operations that contain a certain sidechain ID. It then executes the smart contract function specified in the operation data and packages it into a block which is added to the sidechain. It also maintains the current state of the sidechain and all smart contracts running on it which can be queried using a familiar RPC API.
