A digital encrypted currency transfer method for a block chain

Abstract

The invention discloses a digital encrypted currency transfer method for a block chain, and the method comprises the steps that a user terminal sends a digital encrypted currency transfer request to ablock chain network, and the request comprises a first timestamp, one or more first private key signatures, a source transaction address, and a destination transaction address, wherein the first private key signature is a private key signature of other user terminals; the block chain network reads the digital encrypted currency transfer strategy according to the source transaction address and verifies the digital encrypted currency transfer request, wherein the digital encrypted currency transfer strategy comprises one or more first public keys and a transfer condition, wherein the first public key is a public key of other user terminals; if the digital encrypted currency is verified to be legal, the digital encrypted currency is transferred from the source transaction address to the destination transaction address, transaction behaviors are recorded, and transaction is finished; otherwise, the transaction is ended. According to the method and the system, the user can still use the digital encryption currency under the condition that the private key is lost, and the user is prevented from hosting the digital asset on the third-party platform, so that the security is improved.

Description

technical field [0001] The invention belongs to the field of block chains, and more specifically, relates to a digital encrypted currency transfer method for block chains. Background technique [0002] Digital encrypted currency refers to a digital currency that does not rely on any physical objects and uses cryptographic algorithms. The decentralized nature of the blockchain and the algorithm itself can ensure that the digital cryptocurrency cannot be artificially manipulated through mass production. The design based on cryptography can make digital encrypted currency can only be transferred or paid by the real owner, which also ensures the anonymity of digital encrypted currency ownership and circulation transactions. [0003] Digital encrypted currency is mainly divided into open mining encrypted currency and issued encrypted digital currency. Its core feature is that it does not rely on the issuance of legal tender institutions, and uses a distributed database composed ...

AI Technical Summary

Problems solved by technology

[0004] However, there are some problems that cannot be ignored in the current digital encryption currency: First, there is no effective and controllable solution to deal with the loss of the user's private key. Once the user's private key is lost, it means that the digital encryption currency owned It can no longer be used; secondly, the user hosts the digital encrypted currency on the third-party platform, which means that the user completely hosts the right to use his digital assets on the third-party platform, and the security is very low
