Problems solved by technology

[0003] However, the above-mentioned bidding method also has many disadvantages: the bidding needs to arrive at the scene and be held at the same time and place, which is very dependent on the geographical location and time. For example, colluding with members to falsely quote bid prices, it is impossible to prove their innocence; as for bidding prices, they can only be determined by the bidders themselves, and there is no way to check historical bid prices, and there is no reference bid price for bidders to refer to, and there is no way to control top bids, which may lead to usury and Illegal fundraising, there is no guarantee that the bidding price is within the scope of the law

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...

Abstract

The invention discloses a bidding method and a terminal based on a block chain. The bidder can realize the competitive bidding through the competitive bidding terminal, the operation is convenient, and the bidding can be carried out without entrustment or arrival at the scene, so as to solve the limitation that the traditional competitive bidding needs the same time and the same place. At the sametime, through the preset bidding price prediction model, to provide competitive bidding reference prices for bidders, the bidding price of each bidding terminal is stored in the block chain, which issafe and reliable, and the bidding price and bidding rules can not be tampered with, thus ensuring the openness, fairness and impartiality of the whole bidding process.

Description

technical field [0001] The present invention relates to the field of bidding social finance, in particular to a blockchain-based bidding method and terminal. Background technique [0002] Private capital is abundant and private finance is very active. Among them, mutual aid finance is the most common. Ordinary people can help each other and benefit each other when they are in urgent need of money for marriage, illness, building a house, or doing business. Usually, the initiator invites several people to participate, and the agreed time is held on schedule. Each time, a certain amount of membership fee is paid each time, which is handed over to one person in turn. The promoters will give priority to using the first membership fund free of charge, and then adopt the method of bidding in each subsequent period, that is, each person writes a bid with a note, and puts it in a box without knowing each other, and the promoter will announce the result. If they are the same, draw lo...
