Embodiment 1
[0089] Please refer to figure 1 , a blockchain-based bidding method comprising the steps of:
[0090] S1. The Ethereum client receives the bidding rules sent by the server, generates a corresponding smart contract according to the bidding rules, pushes the smart contract to the blockchain, and receives the smart contract’s blockchain address and application program Binary Interface ABI;
[0091] Wherein, generating a corresponding smart contract according to the bidding rules, and pushing the smart contract to the block chain specifically includes:
[0092] According to the bidding rules, use the solidity language to write and generate the corresponding smart contract;
[0093] Compile the smart contract to generate the corresponding smart contract binary code;
[0094] Start a private Ethereum network node, and send the smart contract binary code to the private Ethereum network node;
[0095] The binary code of the smart contract is tested through the private Ethereum net...
Embodiment 2
[0116] Please refer to figure 2 , a blockchain-based bidding terminal 1, including a memory 2, a processor 3, and a computer program stored on the memory 2 and operable on the processor 3, and the processor 3 executes the computer The following steps are implemented in the program:
[0117] S1. Send the bidding rules to the Ethereum client, so that the Ethereum client generates a corresponding smart contract according to the bidding rules, pushes the smart contract to the blockchain, and receives the area of the smart contract Blockchain address and application binary interface ABI;
[0118] Wherein, generating a corresponding smart contract according to the bidding rules, and pushing the smart contract to the block chain specifically includes:
[0119] According to the bidding rules, use the solidity language to write and generate the corresponding smart contract;
[0120] Compile the smart contract to generate the corresponding smart contract binary code;
[0121] Sta...
Embodiment 3
[0141] In this embodiment, the above-mentioned block chain-based bidding method is applied to an actual application scenario, the application scenario is bidding at a bidding conference, and the specific implementation method is as follows:
[0142] S1. The Ethereum client receives the bidding rules, generates a corresponding smart contract according to the bidding rules, pushes the smart contract to the blockchain, and receives the blockchain address and application binary interface ABI of the smart contract ;
[0143] The bidding rule is the bidding rule of the highest bidder, that is, the initiator of the first phase of bidding will win the bidding, and the bidding starting from the second phase will be won by the bidder with the highest bidding price;
[0144] Wherein, generating a corresponding smart contract according to the bidding rules, and pushing the smart contract to the block chain specifically includes:
[0145] According to the bidding rules, use the solidity l...
