“Sepolia and Goerli are considered the two testnets the ecosystem plans to support,” said Parithosh Jayanthi, a DevOps Engineer at the Ethereum Foundation, to CoinDesk. “Goerli has a relatively large dapp (decentralized applications) ecosystem and allows users to join the validator set in order to test their staking setups. Sepolia is a relatively new testnet and has a small state size, making it easy to use for experimentation,” Jayanthi added.
