An agreement method of a block in a blockchain network by a chair node includes: receiving, from a plurality of congress nodes in a congress, information on an exceptional situation which occurred during agreement processes of a block; transmitting an empty block agreement start message including information on the exceptional situation and verification data for the exceptional situation to the plurality of congress nodes; generating a candidate empty block which does not include a transaction when receiving a delegate request message from at least two congress nodes among the plurality of congress nodes and transmitting the candidate empty block to committee nodes; and generating a final empty block when the candidate empty block is verified by the committee nodes and transmitting the final empty block to all nodes in the blockchain network is provided.

A distributed transaction and data storage platform including a distributed notary ledger or blockchain and one or more individual user micro-identifier chains that together enable the secure effectuation and recordation of one or more transactions, and/or storage of data in an automated, real-time, zero-trust, globally data law and privacy law centric manner while maintaining transaction party confidentiality and preventing chain poisoning.

I present here methods to have 100 percent identification of an art /artifact at digital format.

A service providing method of the present invention includes receiving sound source information on a sound source to be registered to the music platform and issuing a blockchain-based NFT that represents an ownership for the sound source; receiving a request for using a service related to the sound source registered to the music platform from at least one at least one service use terminal connected to the blockchain-based network; and in response to the received request, providing a service related to the sound source based on the blockchain-based NFT issued in advance for the sound source to the at least one service use terminal.

In an aspect, an apparatus for managing smart contracts is presented. The apparatus includes at least a processor and a memory communicatively connected to the at least a processor. The memory contains instructions configured the at least a processor to generate a smart contract. The smart contract comprises at least a non-fungible token (NFT) having a unique token identification and a unique digital address. The at least a processor is configured to bridge the smart contract to a virtual machine. The at least a processor is configured to deploy the smart contract, wherein upon deployment a replica of the at least a NFT is generated. The replica has the same unique token identification as the at least a non-fungible token.

A distributed transaction and data storage platform including a distributed notary ledger, chain arrayed data store or blockchain and one or more individual user micro-identifier chains that together enable the secure effectuation, recordation and sharing of one or more transactions including electronic health record non-fungible tokens, and/or cybersecured storage of data in an automated, real-time, zero-trust, globally data law and privacy law centric manner while maintaining transaction party confidentiality and preventing chain poisoning.

The present application discloses a blockchain-based image transaction system, method, and apparatus. An exemplary method comprises: receiving a target image uploaded from a transaction node in a blockchain, wherein the target image is provided to the transaction node by a user; authenticating, based on image content of the target image, copyright of the target image; if the authentication is successful: generating a copyright certificate of the target image; sending the copyright certificate to the transaction node for the transaction node to display the copyright certificate and a preset prompt window to the user, wherein the preset prompt window inquires the user whether to make the target image as an image available for transaction; and if confirmation information is received, adding the target image into an image transaction pool, wherein the confirmation information indicates the user has determined the target image as an image available for transaction.

Disclosed are a method and device for performing credit evaluation on a work publisher on the basis of a blockchain. The method and device can perform originality analysis on a target work published by a target service node to the blockchain so as to obtain an originality representation value corresponding to the target work. If the originality representation value is low, a copyright credit score corresponding to the target service node is deducted. The deduction is subjected to consensus verification performed by a plurality of service nodes and can only be made public in the blockchain after the consensus verification is successful. The blockchain can publicize a copyright credit score deduction record corresponding to the target service node, based on which the copyright credit score corresponding to the target service node can be determined. The lower the copyright credit score, the poorer the credit level of the target service node.
