Embodiment 1

[0079] like figure 1 As shown, the transaction information is broadcast to all nodes;

[0080] the node collects transaction information in a block;

[0081] The node starts to generate random strings continuously, and calculates the random number answer;

[0082] When a node's answer matches a random number, it broadcasts the generated block to all other nodes;

[0083] All other nodes verify the transaction, and when it is determined that the transaction contained in the block is valid, all other nodes accept the block.

[0084] All the other nodes start creating new blocks and add the cryptographic hash of the block just accepted.

Embodiment 2

[0086] like figure 2 As shown, the blocks are randomly hashed and linked into a blockchain.

[0087] The cryptographic hash formed by the previous block is used to connect the blocks to realize the ordering of past transactions.

[0088] The blockchain must be linked to the previous block before the transaction can be further confirmed.

Embodiment 3

[0090] like image 3 shown, the verification includes a key pair;

[0091] The key pair includes a public key and a private key;

[0092] The public key has publicity and is used to encrypt a piece of information and prove the authenticity of the information;

[0093] The private key has privacy, and the private key is only mastered by the information owner to decrypt the information encrypted by the public key;

[0094] The information encrypted by the public key can only be decrypted by the person who has the corresponding private key;

[0095] The public key and the private key code have asymmetry, that is, the private key cannot be derived from the public key;

[0096] The private key signs the information, and the public key verifies the signature;

[0097] The information verified by the public key signature is confirmed to be issued by the private key holder;

[0098] The public key is issued by the previous block, and the private key is owned by the next block hol...

Abstract

The invention discloses an asymmetric encryption block chain identity information authentication method, which is characterized by comprising the following steps that: transaction information is broadcasted to all the nodes; the node collects the transaction information in one block; the node starts to continually generate random character strings, and calculates a random number answer; when the answer obtained by one node is matched with a random number, the node broadcasts the generated block to all the other nodes; and all the other nodes authenticate the transaction, and accept the block when confirming that the transaction contained in the block is valid. All the other nodes start to create a new block, and add an encryption hash of the block accepted just now. The blocks are randomly hashed and chained together to form a block chain. The encryption hash formed by the previous block is used for connecting the blocks together, and arranging the blocks according to an order of past transaction. After the block chain is chained together with the previous block, transaction can be further confirmed.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular, to a method and device for verifying identity information of an asymmetric encrypted blockchain. Background technique [0002] The Internet TCP / IP protocol has brought us into the era of free transmission of information, and the innovation of blockchain will bring us into the era of free notarization of information! The blockchain establishes "credit" through the whole network accounting and P2P collaboration. It is the fourth milestone in the history of human credit evolution after blood kinship credit, precious metal credit, and central bank banknote credit. There are extensive and in-depth application scenarios in many fields such as global market remittance, intellectual property protection, property micro-notarization, Internet of Things finance, and smart agreements. [0003] The existing blockchain link encrypts the information content and sends it to a spe...
