Call summary
Targets
- •DevNet 5 spec PR to be opened by tomorrow (May 14) — 00:12:06
Decisions
- •Stay on 3SF Mini for now; do not switch to Goldfish until stability is confirmed — 00:22:19
- •Stabilization phase defined as: scale validators → integrate execution → launch public devnet — 00:23:47
Highlights
- Documentation:
- ·New 'Cryptographic Specs' repo created by Justine Traglia to formally verify cryptography (SSZ, Poseidon, XMSS) in Lean with Python bindings — 00:34:37
- Client Updates:
- ·Zeam: fixing multi-subnet aggregation issues; scaling to 128 validators next — 00:11:17
- ·Ream: running bottom-up multi-client devnets; stable to ~4700 slots with 3 clients — 00:12:57
- ·Ethlambda: new devnet 5 Docker image coming this week; passing most Hive spec tests — 00:17:14
- ·Grandine: CPU issue fix in progress; ~11 Hive tests will intentionally fail (no DB yet) — 00:19:11
- Testing Progress:
- ·Ream, Ethlambda, and Gean have integrated HiveSpec test runner; other clients urged to do the same — 00:12:57
- ·Multi-subnet devnet running; aggregation not completing within slot interval for some clients (3–4s observed) — 00:37:50
- Roadmap And Priorities:
- ·DevNet 5 spec PR expected imminently; focus is recursive aggregation with single on-chain proof — 00:22:06
- ·Decision to hold on switching from 3SF Mini to Goldfish until stability is confirmed — 00:22:19
- ·Agreed plan: scale validators first, then integrate execution layer for full validator lifecycle and public devnet — 00:23:47
- ·LeanVM DevNet 5 branch on Lin Multisig is usable; currently on Cole Albert field, not Goldilocks (2x+ perf penalty) — 00:33:15
Action Items
- •All lean client teams — All lean clients: integrate HiveSpec spec test runner in Hive — 00:12:57
- •Thomas Coratger, Gajinder Singh, lean client teams — Agree async on minimum validator count target before proceeding to execution integration — 00:27:24

- Parthasarathy Ramanujam
@Shariq Naiyer can you pls confirm if you are running these multi client devnets on the same machine? Or is this multi-machine devnet?
- Shariq Naiyer
Same machine currently. Will soon be shifted to multi-machines.
- Parthasarathy Ramanujam
Replying to "Same machine current..." Ok noted.
- Parthasarathy Ramanujam
Reacted to "Same machine current..." with 👍
- Gajinder Singh
yea it is sort of stable as such
