Embodiment Construction

[0022] In order to make the purpose, technical solution and technical effect of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The present invention constructs an account-based blockchain system, which supports smart contracts, and the funds in the system are anonymous, and the consensus mechanism is no longer limited to PoW, but can be realized through the alliance chain. At the same time, by combining the account-based alliance chain with anonymous funds, smart contracts, zero-knowledge proofs, and ring signatures, a blockchain-based sealed bidding domain name auction method is proposed, which achieves fair transactions, fair bidding, and funds Guarantee and privacy of funds.

[0024] The block chain system includes: an account structure module, a transaction structure module, a transaction propagation module, and a transaction packaging module.

[0025] The account struc...

Abstract

The invention relates to the technical field of blockchains, in particular to a sealed bidding domain name auction method based on a blockchain, and the method comprises: in the blockchain, a domain name owner creates a domain name auction contract, carries out the validity check of the domain name auction contract through employing a consensus mechanism, and records the information of a bidder; when the bidder finds the domain name auction contract existing on the blockchain, the bidder calls and verifies the commitment, and participates in bidding after the verification is passed; after the bidding time is up, each bidder completes bid uncovering after passing the inspection of a consensus mechanism; and after the bid is uncovered, anyone can check the bidding record, the bidder completes bidding according to the respective state, and the auction is finished. According to the invention, transaction fairness, bidding fairness, fund guarantee and fund privacy in the domain name auction transfer process are realized.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for auctioning domain names with sealed bids based on block chains. Background technique [0002] The Domain Name System (DNS) is one of the important infrastructures of the Internet. Because of its appearance, people no longer use difficult-to-remember IP addresses to access websites, but use easy-to-understand and remember domain names. The basic function of DNS is the management of root domain names and top-level domain names. At present, root domain names and top-level domain names are mainly maintained by the Internet Corporation for Assigned Names and Numbers (ICANN), so this centralized architecture is vulnerable to attacks, such as single point of failure and abuse of power. The famous DNS single point of failure event is the Dyn network attack event in 2016. Due to the failure of the DNS provided by Dyn, many websites including Amazon.com, GitHub, Twitte...
