Golden Finance reported that with the retirement of the Ethereum Goerli test network in January 2024, a new Ethereum test network named "Holesky" will launch next month. The name still follows the tradition of naming test networks after train stations, and the name "Holesky" comes from a subway station in Prague called Nádraží Holešovice. Although Holesky is designed to be very similar to Sepolia, its purpose is more focused on infrastructure and protocol development. Meanwhile, Sepolia will still be the preferred testing ground for Ethereum-based applications. Unlike Sepolia, Holesky will have a fixed supply of test network tokens. However, the upper limit of 1.6 billion is still far higher than the total supply of ETH on the mainnet, which is currently around 120 million.
