The invention provides a Blockchain-based sub-account transaction processing method, system and device. The method comprises the following steps: a terminal receives a private key of a user and account transfer information including a sub-account address, wherein the sub-account address includes a main account address; the account transfer information is signed through a private key to obtain a transfer information ciphertext; an account transfer request including the account transfer information ciphertext and a public key to the Blockchain node; the Blockchain node obtains a corresponding sub-account address and a main account address according to the account transfer request; and whether the sub-account is the sub-account of the user is determined according to the sub-account address and the main account address. A plurality of accounts of the user are constructed into a main account and a plurality of sub-accounts, and the addresses of the sub-accounts comprise the address of the main account. A plurality of accounts adopt the same private key, so that the situation that a plurality of private keys are mixed or forgotten is avoided. And whether the sub-account is an account owned by the user is determined according to the sub-account address and the main account address, so that the account can be identified in time under the condition that the account is stolen, and user loss is avoided.
Description
technical field [0001] The application belongs to the technical field of block chain, and specifically relates to a block chain-based sub-account transaction processing method, system and equipment. Background technique [0002] At present, in the blockchain account, a private key corresponds to an account. When a user initiates a transfer request, the private key is used to sign the transfer amount and the destination account address, and the signature and the public key corresponding to the private key are carried in the transfer request. After receiving the transfer request, the blockchain node decrypts the signature in the transfer request through the public key carried in the transfer request to obtain the transfer amount and destination account address. Then use the asymmetric encryption algorithm to calculate the public key to obtain the user's account address, then transfer the transfer amount from the user's account address, and transfer the transfer amount to the d...
