Protects Smart Contracts

Developers welcome the innovative FireWall.X to the EOSIO family. Built to act as an effective security measure for smart contracts against malicious attacks and cyber threats, this development can only serve to protect the overall health of the EOS ecosystem.

We spoke to Zhong Qifu, Product Manager at SlowMist Technology Co. (the company behind FireWall.X), about how “the world’s first firewall for smart contracts” intends to be the security guardian of all EOS applications.

FireWall.X is a powerful and practical firewall for smart contracts — it is also the world’s first firewall for smart contracts.

Similar to traditional firewalls for operating systems that control network traffic, FireWall.X can also execute control over inline actions and prevent unauthorized access to smart contracts.

Used With Oracle Technology

Used in combination with oracle technology, there is the added benefit of risk management, which will help prevent hackers from obtaining any account information contained in smart contracts. For developers, FireWall.X makes their development process a lot easier since all they need to do is to directly import their smart contract security enforcement document into their own code, after which they will be able to create a smart contract that is more resistant against cyber attacks — all at zero cost.

Hacked Their Way To The Solution

In the latter half of 2018, they conducted some research into the many different ways one could carry out smart contract hacks and discovered some of the major pain points and challenges surrounding the safety precautions of smart contracts. Following one of their many brainstorming sessions, a cybersecurity researcher on their team proposed the idea of FireWall.X, which naturally led them to the creation of this project. Their team’s expertise also lies mainly in cybersecurity technology, which is why they chose to focus on this aspect in the first place.

Who Is On The Team?

Their team possesses deep expertise and experience in cybersecurity-related matters. Many of their members have worked at eminent tech corporations such as Google, Microsoft, W3C, Tencent, Alibaba, Baidu, etc., and some of their project achievements have been featured at the Black Hat Briefings — one of the most well-attended information security conferences in the world. So far, they have provided many EOS-based decentralized exchanges, wallets, and smart contract developers with security audits. Their clients include WhaleEx, Newdex, Chaince, MORE.TOP Wallet, MEET.ONE etc.

When the public network launched in June 2018, their team compiled a guide titled “EOS BP Nodes Security Checklist”, aimed at providing community members with smart contract security support. In the following September, they utilized their experience in carrying out smart contract security audits to create a ‘Best Practice’ guide on ensuring the secure implementation of EOS smart contracts.

User-Friendly Platform For Developers

At present, some of the fully functioning features of FireWall.X include malicious account screening, blacklist and whitelist management, statistical analysis, activity logging, as well as malicious transfer detection. These are all provided on a user-friendly platform for developers. Down the line, they will be launching a real-time statistical panel, as well as introducing risk management features in combination with an off-chain analysis tool. In a nutshell, these features and tools would enable apps to block off attacks in a timely manner, thus reducing the financial loss of users.

Blockchain technology is superior in that it offers the benefits of immutability and accountability, which ensure that no data can be tampered with in the process. Blockchain can also improve identity verification and data authorization, which helps massively with elevating the efficiency of threat intelligence sharing. This is especially pertinent to their project, as it is centered on preventing cyber attacks. As for choosing to build on EOSIO, that’s because it is fast and easy to use. Since the launch of the public network, they have continuously seen a growing number of apps developing on the EOSIO protocol — this gives them high hopes for the EOSIO ecosystem.

Large Volumes Of Contract Hacks Blocked

They have already seen lots of positive responses to their project among members of the EOS community. So far, they have managed to get 23 projects on board with implementing FireWall.X. They have successfully blocked off a large volume of smart contract hacks, in the process protecting many apps from cyber attacks.
