Instant execution method of block chain based on homomorphic encryption

Abstract

The invention discloses an instant execution method of a block chain based on homomorphic encryption. The instant execution method includes the steps: encrypting data needing to be shared by using ahomomorphic encryption algorithm; outputting the encrypted data; jointly generate cooperation parameters by multiple participants; and verifying that the input and output of the encrypted ciphertext amount in the transaction are equal, and executing a response or write operation on accounts of a transaction initiator and a transaction receiver with readable or writable authority, wherein incentivepayment is used for encouraging a resource provider to share redundant memory and bandwidth resources as cache nodes of a transaction flow. According to the instant execution method of a block chainbased on homomorphic encryption, the block chain is used to carry out hierarchical linking on each service node, so as to ensure that the data exchange record is real and reliable and cannot be tampered, and meanwhile, for the data distribution problem, in combination with a blockchain cross-chain and instant execution contract technology, the blockchain-based data distribution system is provided,thus changing the traditional data distribution mode, and promoting the system maintenance on the system safety, stability and other performances through an incentive payment excitation measure.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular, to an instant execution method of block chain based on homomorphic encryption. Background technique [0002] Multiple Atomic Chain (MAC for short) is the third blockchain underlying ecosystem developed outside of Bitcoin and Ethereum. Users can truly feel the value of blockchain technology, so that blockchain is not stagnant at the level of academic theory but more directly applied to the practice of development and application. The spark of technology collision is also a challenge to the existing technology of the blockchain, jumping out of the thinking of the existing technical field, and becoming the pioneer of the blockchain 3.0 ecological application system. In the Duoyuan chain system, point-to-point value transfer can be realized through the value transfer protocol. High performance, high throughput, fast and safe are the characteristics of Duoyuan chain, so t...

Problems solved by technology

The disadvantages of this method are: the client will directly hand over the private key to the proxy server, which will cause the proxy server to completely replace the client, which will cause a fatal privacy leak; only a single client will complete the determination of the ciphertext. The application range is too narrow, which is not conducive to promotion and use; the transaction occurrence server and transaction acceptance server can collude and are vulnerable to attack, which brings great security problems
