COSE-based envelope separating encryption metadata from ciphertext; single-shot and seekable chunked AES-256-GCM schemes
Open: Discussion #1253. Open: scheme 1 test vectors, shared 1 MiB prefix-read cap
Draft (@Kubuxu, @BravoNatalie); approved for draft, awaiting code-owner reviewsNot tied to a network upgrade—
Carried overFIP-0107: Implicit messages in block receipts
Adds implicit messages (cron, reward) to block receipts; deferred from NV29 for lack of Lotus & Forest bandwidth
Open: commit to NV30 with named Forest/Venus owners, or defer again
Accepted; Lotus PR #13539 open, Forest/Venus TODODeferred NV29 → NV30; decision at Implementors CallM
Carried overFork Signaling Repurposing
Uses the unused 64-bit BlockHeader.ForkSignaling field to signal miner software ID, upgrade readiness, actors bundle version and upgrade epoch offset
Open: Not consensus-critical; likely an FRC
In discussion; possible, needs bandwidth to implementDeferred NV29 → NV30; can ship without a network upgradeS
Carried overSealer ID
Assigns a unique ID to sealers; significant miner-actor change
Open: re-scope, defer again, or withdraw
Draft PR open since Apr 2024; not in progressDeferred NV28 → NV29 → NV30; high-risk, decision at Implementors Call—
Carried overF3 Calibration Smart Contract Activation
Lets the F3 activation date be set via smart contract on Calibnet for easier testing and resets
Open: still needed for NV30 testing, or close
Not in progress (implementation issue, not a FIP); F3 restarted on Calibnet 2026-02-12Deferred NV28 → NV29 → NV30; decision at Implementors CallL
