The signatures of the proposal node, the anonymous auction node and the notarization node are checked for each auction to determine the validity of auction transaction, and if the auction node with the highest bid pays the money corresponding to the quotation message to the operation node, the operation node signature is needed before the block is finally fallen to confirm the payment condition; if the auction node with the highest bid pays the payment corresponding to the quotation message to the proposal node, the proposal node signature is needed before the final block is dropped to confirm the payment condition.
The following provides an application scenario of the online auction system, in which when a certain commodity is auctioned, such as a Buddha drawing, in an online auction transaction scenario based on the blockchain technology, an auction transaction proposal is generated by a proposal node, and the auction transaction proposal is broadcast to all nodes in a public blockchain network; after each anonymous auction node receives the auction trade proposal, bidding in the effective auction time, generating quotation messages for the auction trade proposal based on the anonymous accounts, and broadcasting the quotation messages to each node in the public blockchain network; executing a preset consensus algorithm, determining an anonymous auction node with the highest bid according to the quotation message, determining the anonymous auction node with the highest bid as an accounting right node, paying money corresponding to the quotation message of the accounting right node to an operation node or a proposal node by the accounting right node, and after payment is completed, signing a transaction block by the operation node or the proposal node by adopting a corresponding private key to confirm that the accounting right node pays money, so that a beat can be obtained. If the highest-bidding anonymous auction node comprises a plurality of anonymous auction nodes, comparing the bidding time of the highest-bidding anonymous auction nodes with the same price, and acquiring the block accounting right of the auction transaction by the highest-bidding anonymous auction node, wherein the whole process is realized through the anonymous auction nodes and the intelligent contract; if no anonymous auction node bids, the transaction is invalidated and the block account book is not written.
The following description of the related terms of Blockchain refers to many scientific and technical problems of mathematics, cryptography, the internet, and computer programming, for the Blockchain (Blockchain). From the application perspective, the blockchain is simply a distributed shared ledger and database, and has the characteristics of decentralization, non-falsification, whole trace, traceability, collective maintenance, disclosure transparency and the like.
