Most Ethereum testnets help people to experiment with deploying decentralized apps and smart contracts before they go live on the primary Ethereum network. However, only a few of these testnets are managing to stay secure and consistent. The latest Ethereum testnet app, Görli Testnet will resolve all of these problems.

Understanding the importance of testnets

Before a smart contract can be distributed onto the Ethereum mainnet, the developer must carry a range of test to guarantee the safety and efficiency of the platform. This testing process requires the creation of a similar network to that of the mainnet. Nevertheless, since most blockchain systems use smart contracts for paying gas for all their computations within the primary system, determining how to run these testnets for free remains a critical challenge that developers face.

Testnets are highly vital to the quick contract creation process as they allow developers to run comprehensive tests before the contracts go live with no need for paying for the service. The significant differentiating factor in these testing networks is their financial incentive. Most testnets use PoA as the consensus framework rather than the PoW that is utilized on blockchain systems. Although blockchain systems safeguard against mass computation, the PoW, testnets are protected by a preset validator nodes group, the PoA.

About Görli Testnet

According to the CEO and co-founder of ChainSafe Systems, Aidan Hyman, this Görli Testnet represents a new system where both Parity and Geth Ethereum clients can work as the network’s validators. Although the two primary clients used for running the Ethereum ecosystem are Parity and Geth Ethereum, the testnets that they use, Kovan and Rinkeby, are completely isolated from each other. Hyman added that the reason for this separation was because the testnet clients used different PoA consensus mechanisms.

The goal, therefore, for Görli was to create multiple testiness across different Ethereum clients, whether Parity or Geth. ChainSafe Systems took part in the recent ETHBerlin conference, where they noted that they had already started implementing Aura, Parity Ethereum’s consensus mechanism, into Geth. Upon further research and developments, the ChainSafe systems team decided to add a distinctive flag for the Görli blockchain in every client, and also write the Aura PoA in Go.


Hyman added that his Görli team of developers would continue to advance the project further, including reaching out to Parity and Geth Ethereum teams to better comprehend the inner workings of the Aura PoA consensus mechanisms. He reiterated that the plan was to re-implement Aura PoA into Geth and get it ready for upstream usage. The hopeful result for this new testnet is creating a safe and reliable solution that will enable smart contract developers to work efficiently.
