# peerdas-devnet-7 specs :::info :mega: peerdas-devnet-7 targets launched on 9th May 2025 ::: :::info :mega: peerdas-devnet-7 will have target/max blob 6/9 similar to pectra. Any bump in blob increase will be done via BPO in future devnets and not via `max_blobs_per_block_fulu`. ::: ### Changes include: - Data column sidecars by root - validator custody (optional) - distributed blob building - shifting cell proof computation to transaction sender ### Discussion: - Who is going to work on EELS/EEST for proof computation to tx sender? ## EIP List for peerdas-devnet-7 The list below links the specific commit versions of the EIPs included in devnet-7.
