🟣 Ethereum is deploying its most significant upgrade since The Merge on mainnet today: Fusaka. An improvement that remains invisible to users for now, but long-term effects are essential for the network scalability. Fusaka combines two upgrades: Osaka (execution) and Fulu (consensus), for a total of 13 EIPs that extend the work initiated with Dencun and Pectra on L2 scalability and blob infrastructure. The core advancement is PeerDAS, a system that distributes blob data across validators instead of requiring each of them to store everything. The goal is clear: increase blob scalability without raising hardware requirements, while preserving Ethereum’s decentralization. Fusaka also introduces several mechanisms to stabilize the blob market: a floor price to ensure validator profitability, and a simplified process to adjust the number of blobs per block as L2 demand grows. The gas limit per block is raised once again, and several internal optimizations strengthen client robustness and improve predictability for validators. Fusaka does not change the user experience today. But it prepares Ethereum to absorb the growing activity of L2 networks and blob usage over the coming years. Our full analysis is available below.
