Cryptocurrency automatic extraction method and system

Abstract

The embodiment of the invention discloses an automatic cryptocurrency extraction system. The system comprises a transaction machine, a signature machine and a node machine, wherein the node machine isa blockchain network full node of cryptocurrency; the transaction machine generates an unsigned coin withdrawal transaction, sends the coin withdrawal transaction to the signature machine for signature authentication, and forwards the signed coin withdrawal transaction to the node machine for broadcasting; the signature machine stores the encrypted wallet file, and is responsible for obtaining ato-be-signed transaction from the transaction machine and sending the transaction back to the transaction machine after signing the transaction. The automatic extraction method specifically comprisesthe steps of generating a to-be-extracted currency record, and performing tamper-proof signature on the to-be-extracted currency record; sending the cryptocurrency transfer transaction to a signaturemachine; extracting a private key from a local encrypted private key file of the signature machine, and signing the to-be-signed transfer transaction; calling an interface provided by the node machineto broadcast the signed currency transaction to a blockchain network of the cryptocurrency; according to the scheme, transaction, signature and block data are separated, so that the wallet is prevented from touching the network and external attack risks are prevented.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of encrypted currency extraction, in particular to a method and system for automatically extracting encrypted currency. Background technique [0002] In recent years, with the widespread application of cryptocurrency based on blockchain technology, more and more B2C Internet platforms have begun to support cryptocurrencies such as Bitcoin and Ethereum. Members on these platforms use cryptocurrency payment platforms With the services on the platform, members can also spend their energy on the platform to earn cryptocurrency income. These platforms usually store the account balance of platform members in the database. Members will deduct the balance when they consume on the platform, and members will increase the balance if they earn cryptocurrency. Therefore, the platform needs to provide a cryptocurrency withdrawal system. This system is also called the platform's hot wallet. Members can...

Problems solved by technology

[0004] (1) This wallet is an encrypted currency full-node wallet. The private key of the wallet and the full node of the blockchain cannot be separated. The private key of the wallet has a security risk of being connected to the Internet. If the server gets the private key of the wallet, all the cryptocurrencies in the wallet may be stolen by hackers;

[0005] (2) In order to realize the automation of cryptocurrency extraction, the existing technology uses the interface provided by the business system to call the wallet to realize the currency extraction, which will expose the access interface of the wallet. Once the calling authority is maliciously controlled, the encrypted assets in the wallet Dangers of possible malicious extraction
