Abstract

The invention provides a smart contract dedicated chip device, an execution method and a block chain node device. The smart contract dedicated chip device comprises an interface unit, a scheduling unit, a cryptography unit, an on-chip storage unit and a smart contract execution unit. The cryptographic unit is used for carrying out cryptographic operation in the execution process of the smart contract; the scheduling unit is used for realizing interactive scheduling and control operation among the units in the execution process of the intelligent contract; and the smart contract execution unit is used for performing smart contract execution operation according to the received smart contract code and the target data of the smart contract, and returning smart contract execution result data. By adopting the special chip device for the smart contract disclosed by the invention, the user privacy data and the smart contract code can be prevented from being maliciously read and leaked, and the data communication between the chip device and the block chain node host and the authenticity and integrity of the smart contract code are ensured, so that the security of smart contract execution is improved.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a chip device and an execution method dedicated to smart contracts. In addition, it also relates to a block chain node device. Background technique [0002] With the rapid development of network technology, blockchain-related technologies have gradually matured. More and more companies are beginning to research blockchain-related technologies as key content. Blockchain can be regarded as a special shared database, whose main feature is that the data or information stored in it is unforgeable, traceable, and collectively maintained. Building a digital "trust" foundation based on blockchain technology and incorporating it into the future digital infrastructure can provide a solid "trust" platform for digital information, build a reliable "cooperation" mechanism, and combine specific application and has broad application prospects. As an important extension and supplement of...
