Abstract

The present invention provides a Scala-based blockchain contract implementation method and system. The method includes: statically compiling the contract in an integrated development environment, and implementing the contract interface call through interface abstraction combined with a class reflection mechanism; The class is named; the compiled contract is tested through the ScalaTest toolkit; the contract that passes the test is entered into the block through the signature transaction consensus of the Deploy type, and after the block is generated, the dynamic compilation and loading of the Scala contract class is realized through the class reflection mechanism. Network deployment; call the contract according to the contract identifier returned by the deployment. The present invention can use the Scala language which is Turing-complete and has been tested by engineering practice as the contract development language to expand the application scenarios of the block chain. difficulty.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a Scala-based block chain contract implementation method and system. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. [0003] However, with the widespread use of the blockchain, there are issues that need to be adapted to more application scenarios and allow third parties to write, sign, deploy, and sign calls to contracts. Contents of the invention [0004] The Scala-based block chain contract implementation method and system provided by the present invention can use the Scala language that is Turing-co...
