Abstract

Embodiments of the present invention provide a method for providing an intelligent contract in a block chain network, comprising receiving an installation request for the intelligent contract, the installation request including an installation destination of the intelligent contract; generating encrypted smart contract source code; generating key acquisition information associated with the encrypted smart contract source code, the key acquisition information being used to acquire a key, and the key being used to decrypt the encrypted smart contract source code; and providing the encrypted smart contract source code and the key acquisition information to the installation destination. The method for providing the intelligent contract in the block chain network according to the embodiment ofthe present invention can effectively guarantee the transmission security of the source code of the intelligent contract on the block chain and ensure that the source code is not obtained by an unauthorized party, thereby protecting the privacy of the source code of the intelligent contract on the block chain.

Description

technical field [0001] Embodiments of the present invention relate to blockchain technology, and more specifically to a method for providing smart contracts in a blockchain network, a method for installing smart contracts in a blockchain network, and a method for installing smart contracts in a blockchain network. An apparatus for performing the above method and a corresponding computer-readable storage medium. Background technique [0002] Blockchain (Blockchain), as an emerging technology that has emerged in recent years, has been widely discussed and researched. Blockchain is an intelligent peer-to-peer network that uses distributed databases to identify, disseminate and record information, also known as the Internet of Value. Blockchain technology includes storing data in a block structure, using cryptography to ensure transmission and access security, etc., which can realize data consistent storage, anti-tampering, and a decentralized technical system. [0003] A smar...
