Embodiment Construction

[0054] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055] The emergence of blockchain technology solves the problem of mutual trust in multi-party transactions, and the distributed ledger is an important part of it. How to quickly and safely obtain data from the ledger is a problem that blockchain technology is committed to solving. However, in the existing technology, there is a gap in the control of calls between smart contracts, allowing blockchain attackers t...

Abstract

The present application provides a method and apparatus for managing invocation between intelligent contracts. The method comprises the following steps: when detecting that the first intelligent contract initiates the invocation request to the second intelligent contract, analyzing the invocation request, wherein the invocation request comprises a caller, a called part, a first credential and a timestamp; according to the caller and the callee in the call request, searching the operation factor of the corresponding caller in the registry of the block chain, and obtaining the second credentialaccording to the operation factor and the timestamp of the caller; Judging whether the second voucher matches the first voucher; If the second credential matches the first credential, the first smartcontract is executed to invoke the second smart contract. Thus, the invocation between intelligent contracts can be managed, and the invocation between intelligent contracts can be guaranteed to be reliable and safe.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a method and device for managing calls between smart contracts. Background technique [0002] Blockchain is a decentralized distributed accounting technology derived from Bitcoin, which generates persistent unmodifiable records by superimposing encrypted block data in chronological order, and stores the records in the blockchain network In each node, each node participating in the blockchain jointly maintains its own database. As a result, the blockchain has technical advantages such as decentralization, anti-tampering, consistent data storage, and transparent and traceable processes. Wide application prospects. [0003] Smart contracts are computer programs that can run exactly on the blockchain. Users use smart contracts to conduct transactions, share data, and establish trust, and the characteristics of blockchain technology ensure that the entire process of ...
