PalletOne has currently completed the development of contract template specified node execution and joint-debugging function. The usage of contract template mainly includes three processes of installation, deployment and contract execution of contract template. The docker is used as the basic environment for contract operations, ensuring the security and independence of contract.

Normal user contract uses VRF to ensure the randomness of node selection, thus avoiding the situation of nodes doing anything forbidden. In addition, the function of specifying the node operation during contract installation is added, and the security is ensured by means of permission control to satisfy the scenario of some commercial deployment contracts.
