Embodiment Construction

[0020] see Figure 1 to Figure 3 , a communication method based on blockchain, proceed as follows:

[0021] Step 1. Establish several clients on the blockchain network. The clients are divided into full-message clients and light clients. The full message client is a client used to store messages on the entire network; the light client is a client that only stores relevant messages of the client. The message processing and communication process of the full message client and the light client are the same, but the types of stored messages are different. A full-message client stores all messages, and a light client stores only its own client-related messages.

[0022] Step 2. Assign a communication address to each full-message client and light client. The communication address is a public-private key pair generated using an encryption algorithm, where the private key is stored locally and the public key is published as the address for receiving messages; the encryption algorith...

Abstract

The invention discloses a blockchain-based communication method. The method comprises: a plurality of clients are established in a blockchain network and clients are classified into full message clients and light clients; communication addresses are allocated to all full message clients and light clients, wherein the communication addresses are public-private key pairs generated by using an encryption algorithm, the private keys are stored locally, and the public keys as addresses for receiving messages are published publicly; when a message is sent out, the client sending out the message signs the sent message by using the private key generated by the local communication address, a main message body is encrypted by using the public key generated by a communication address of a receiver, the message is transformed into a ciphertext, and the ciphertext as an attached content of the transaction is broadcasted to each full-message client in the blockchain network; and after the full-message clients receive the ciphertext, the ciphertext is packaged into block data, and the block data are broadcasted to each client in the blockchain network. Therefore, a safe, trusted, anonymous, anti-listening communication method is established.

Description

technical field [0001] The present invention relates to a communication method, in particular to a communication method based on block chain. Background technique [0002] At present, many online chat tools are satisfied with people's communication, but they also expose some serious problems, such as security; the traditional centralized communication mode is easy to be attacked, resulting in the leakage of personal privacy, and there is a certain risk of information loss in the network of C / S architecture . [0003] The birth of Bitcoin brought blockchain technology into people's field of vision; the blockchain network based on the p2p protocol provides a decentralized, distributed, and tamper-proof environment without third-party credit guarantees, and uses powerful cryptographic algorithms to provide Communication establishes basic conditions for sufficient security, trustworthiness, anonymity, and anti-monitoring. Contents of the invention [0004] The technical prob...
