This article is to share with you about the use of Beosin-VaaS for Fabric tools. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

What is Fabric?

Hyperledger Fabric is an open source block chain platform under the Linux Foundation, and it is also the chain platform with the largest number of industrial applications, which has been supported by many companies at home and abroad. IBM, AWS, SAP, Oracle, Ant Financial Services Group, Tencent, Baidu, Huawei and other companies have all launched Fabric-based blockchain solutions.

Intelligent contract is called chain code (Chaincode) in Fabric. Like the intelligent contract running on EVM and WASM virtual machines, chain code faces some problems, such as code loopholes, improper permission setting and business logic implementation errors.

Due to the distributed nature of the block chain, if the chain code has security problems, it will directly lead to the loss of the enterprise. The update and maintenance of the chain code requires a large cost, and if the chain code needs to be updated because of security problems, it will also make the enterprise spend a lot of manpower and material resources.

Beosin-VaaS for Fabric

In order to help the chain platform avoid risks and effectively reduce enterprise losses, Chengdu Lianan launched the world's first automatic formal verification tool for Fabric chain codes.

Aiming at Hyperledger Fabric intelligent contract, Fabric-VaaS uses formal verification to detect the contract source code, which can verify more than 20 kinds of risks that can not be detected manually. This technology has been widely used in common chains such as ethereum, ontology, eos and alliance chains such as ant baas.

Aiming at the Hyperledger Fabric intelligent contract, Fabric-VaaS can model the fabric contract system, enumerate all the possibilities on the chain, and verify whether there are security risks through the security rule base. At the same time, the security rule base of VaaS is also constantly strengthening and improving, continuously integrating more security vulnerability rules to protect the whole ecological security of the block chain.

Fabric-VaaS also provides services through API and plug-ins to facilitate user integration, make users use more freely, and develop contracts faster, more secure and more efficient.

The launch of Beosin-VaaS for Fabric, the world's first automatic formal verification tool for Fabric chain codes, provides "military" security verification for chain codes. Effectively detect the general security vulnerabilities of Fabric chain codes, and provide suggestions for vulnerability repair to users to provide security escort for block chain landing applications.
