Devnet / Testing Updates
peerdas-devnet-6 (specs)
Devnet-6 Open Question:

Devnet-6: Who is going to work on EELS/EEST for proof computation to tx sender?

STEEL Updates:

EL changes are limited to the network wrapper that encapsulate blob transaction information and blob data into a gossipable object between peers.  This can be tested via Hive’s Engine simulator.  Tests will be added / updated here.
As there are no changes to the EVM or EL block header, noo changes are required to EELS execution-specs or EEST’s consensus test set.  Therefore:


No peerdas-devnet-6 specific release will be made from EEST
EL clients can proceed with testing using the latest develop release (provided their branches are based on Prague) without waiting for a specific peerdas-devnet-6 release from EEST.

Spec / EIP Discussions
P0 : Open Spec PRs

EIP | Update EIP-7594: include cell proofs in network wrapper of blob txs (one last comment)
consensus-specs | Transition period from 4844-style blob transactions to PeerDAS-style blob transactions (link)
cell proof computation | Add EIP-7594 (PeerDAS) related changes (beacon-api) (builder-specs) (engine-api)
execution-spec-tests | feat(tests): peerdas tracking issue (guessing this is not a blocker, just for tracking)

P1 : Draft Spec PRs

beacon-metrics | PeerDAS metrics: add data column, kzg, custody metrics (link)
execution-specs | More post Prague re-factors (link)

Spec Updates:

Consensus Specs: v1.5.0-beta.4 is scheduled for release Wed April 2nd ( @jtraglia )

Open Discussion
Proposal: Blob schedule for Fusaka (here) by @ralexstokes
