Abstract

The invention discloses an intelligent contract-based digital currency transaction method and device as well as computing equipment. The method comprises the following steps: when a digital current transaction request sent from a first transaction node to a second transaction node is monitored, triggering a script of an intelligent contract layer to automatically operate; in the script operation process, judging whether the digital currency transaction is secure or not according to address information of the second transaction node; if NO, intercepting or prewarning the digital currency transaction. The method monitors a transaction request of the first transaction node, judges a transaction object, namely the address information of the second transaction node, by using the intelligent contract, and intercepts or prewarns the transaction before the transaction is started if the digital currency transaction is not secure, so that the transaction security is guaranteed to the maximum extent, and invocatable economical loss caused by a user is avoided. Based on the characteristic of the digital currency transaction, the method effectively intercepts non-secure transactions by using the intelligent contract under the condition of not affecting normal transactions of digital currencies.

Description

technical field [0001] The present invention relates to the field of software, in particular to a smart contract-based digital currency transaction method, device, and computing equipment. Background technique [0002] Digital currency is an alternative currency in the form of electronic money. Unlike virtual currencies in the virtual world, digital currencies can be used for real goods and services transactions, not limited to online games. Existing digital currencies, such as Bitcoin, Litecoin, and PPCoin, mainly rely on checksum encryption technology to create, issue, and circulate. [0003] Digital currency transactions are different from ordinary currency transactions. After digital currency transactions are traded, there is a problem that they cannot be reversed. For example, in blockchain digital currency transactions, the blockchain associates data blocks into chains in chronological order, generating permanent irreversible records that are open and transparent to ...
