Summary
POA Network is building a Proof of Authority sidechain to Ethereum to facilitate secure, fast, and cheap transactions while being fully compatible with the existing Ethereum ecosystem. A cross-chain bridge allows easy transfer of tokens from a POA Network chain onto the main Ethereum chain and vice-versa. The POA Network system consists of many connected open-source components. Smart contracts form the core and give strong guarantees, dApps and APIs allow for easy access and a custom parity client is running an efficient Proof of Authority based version of Ethereum using the Aura consensus. The audit focused on the core part, the smart contracts deployed on POA Network.
Our audit investigated technical issues such as the initialization of keys and their distribution, the requirements of the validator set, and the upgradability of the smart contracts. We also looked into the reward system and the overall governance to check their soundness and design.
Overall, the ChainSecurity Ltd team found that POA Network is a very well-coded complex system with clean documentation. During the audit, several issues have been found by ChainSecurity Ltd and successfully addressed by POA Network. ChainSecurity Ltd sees no remaining security issues in the current version.
About POA
POA Network is an Ethereum-based platform that offers an open-source framework for smart contracts. Towards the end of 2017, POA Network launched its own blockchain utilizing a new and unique consensus mechanism known as Proof of Authority (POA). POA leverages an independent group of validators who are all licensed public notaries around the United States which increases security while enabling a method of governance on the blockchain. POA Network is scalable, secure and cheaper than other projects, aiming to provide a platform for small and medium sized organizations.
