Ethereum’s Fusaka Upgrade: Sepolia Testnet Activation Marks Significant Progress

The Ethereum test network, Sepolia, has successfully activated the Fusaka upgrade, marking a crucial step towards enhanced scalability and performance. This milestone follows the activation of the Holesky testnet on October 1st, with the Sepolia deployment specifically focusing on stress testing the new data-availability system before final testing. The Fusaka rollout will see the block gas limit increased to 60 million, allowing for more transactions and complex smart contract activities within each block, while also evaluating the stability of nodes under higher capacity load.
