如何防止从仲裁节点部署合约

Question

In quorum.network, every node can deploy smart contract. How can I prevent the node from deploying smart contract or allow only specific node to do this.

Thank.

Answer 1

You can use "privateFor" field while deploying contract.In privateFor object pass the publicKey of participant node. Please refer below code:

web3.eth.contract(contract.abi).new({
            data: "0x" + contract.bytecode,
            gas: 80000000,
            privateFor: ["bvpFyZCYmtPX3hyxNhmPXu0Rn/95S3IoqyK+IiZPlHw="],
            from: owner,
        }

Thanks,

You should consider using enhanced permissioning for Quorum. https://consensys.net/docs/goquorum/en/latest/configure-and-manage/manage/enhanced-permissions/
