Once the order has been received, the contract will be implemented in accordance with the predefined terms. At the same time, the smart contract will also automatically check the implementation of contractual commitments.
How is the Airchain integrated Smart contract specifically?
Smart contracts are the key element of Ethereum Blockchain. In them any algorithm can be encoded. Smart contracts can carry arbitrary state and can perform any arbitrary computations. They are even able to call other smart contracts.
This gives the scripting facilities of Ethereum tremendous flexibility. Smart contracts are run by each node as part of the block creation process, with nodes receiving mining rewards in Ether for their provision of network infrastructure.
