Chengdu LianAn Technology’s Ethereum Trial Version of its All New Smart Contract Formal Verification Platform VaaS is Now Online

Smart contracts serve as the core of the Ethereum ecosystem and has had rapid development throughout the past years. The earliest smart contract can be dated back to 1995, it was first mentioned by cryptologist Nick Szabo. Smart contract has a clear advantage when used intransactions that are complex and involves multiple parties.

However, with smart contract security problems becoming more frequent, it is evident that smart contract also has its disadvantages, including its incapability to control tangible assets, nor can it secure contract execution for tangible assets; it is also difficult to guarantee that the smart contract is executed exactly like how the designer intends it to with no vulnerability.

Problem caused by these vulnerabilities, made the market value of known projects like The DAO, Parity Multi-signature Wallet, BEC evaporate in one night. These problems may easily result in severe problems including the loss of cryptocurrencies, breaking financial order, etc. According to statistics, losses due to security vulnerabilities within smart contract itself make up over 30% of the total losses in the blockchain security industry.

Auditing and verifying smart contract codes is extremely important. Only when smart contract codes are audited and code security is ensured, then smart contracts can play its corresponding role in its future execution and truly avoid risks as well as financial losses that are caused by vulnerabilities in the source code of the contract. However, in the current market, experts have yet to see an effective way to verify and audit smart contracts.

Aimed to solve the security problem in smart contracts, Chengdu LianAn Technology (AKA Beosin) has launched its all new “One-Button” Automated Smart Contract Formal Verification Platform VaaS (you can find the free and simplified version online tailored specifically for Ethereum contracts at: http://www.lianantech.com).

LianAn spent over 1 year in developing the VaaS tool, which uses formal verification as its core technology. VaaS is the first smart contract auditing tool that is developed to support multiple blockchain platforms including (but not limited to) Ethereum, EOS, Fabric, with an accuracy rate of 95%. This makes Chengdu LianAn Technology the first company to utilize formal verification technology in the blockchain security field.

VaaS-ETH simplified platform

It is worth mentioning that compared to semi-automated smart contract formal verification, the VaaS platform’s “One-Button” formal verification tool not only can find smart contract vulnerabilities in 10 different macro categories and 27 micro categories in an automated, fast, high accuracy manner, it can also accurately locate risky codes and point out cause of the risks. Through the auditing process, VaaS can effectively verify common security vulnerabilities, security attributes, and functional correctness of a smart contract.

In order to contribute to the blockchain ecosystem, Chengdu LianAn Technology decides to globally publish its simplified version of VaaS tool for Ethereum contracts, allowing fellow blockchain enthusiasts to experience the “One-Button” smart contract verification tool, audit their own smart contracts, and preventing smart contract security problems in advance.

The three main types of service provided via the VaaS platform can be categorized as the following:

l Providing free smart contract security audit via the free VaaS-ETH trial tool
