Ethereum has successfully activated PeerDAS as part of its Fusaka upgrade, significantly enhancing on-chain data availability. This advancement introduces probabilistic sampling and erasure coding, which effectively reduce node storage requirements. The upgrade allows Ethereum to support up to 48 blobs per block, a substantial increase from the previous 3–6 blobs. PeerDAS is a pivotal step in Ethereum's scalability efforts, maintaining decentralization while advancing towards full Danksharding. This upgrade not only strengthens Ethereum's infrastructure but also positions it more competitively against alternative data layer solutions, reinforcing its roadmap for future development.
