EIP-7607: Hardfork Meta - Fusaka
EIPs included in the Fulu/Osaka Ethereum network upgrade:
EIP-7594: PeerDAS - Peer Data Availability Sampling (source)
Introduces a method for nodes to sample small pieces of data from peers instead of downloading full blocks, improving Ethereum's scalability and reducing resource load on individual nodes.
In plain terms, PeerDAS means Ethereum will be able to handle way more transactions without overloading your computer. The network becomes faster and lighter, which means lower fees and a smoother experience—even during busy times.
EIP-7892: Blob Parameter Only Hardforks (source)
Allows developers to change parameters of blob transactions without requiring a full network upgrade (hardfork), making it easier to adjust how the network operates.
This makes Ethereum more flexible—developers can fine-tune how data-heavy transactions work without waiting months for a big upgrade. For everyday users, that means faster improvements and fewer disruptions.
