Finality rule v3 on the devnet: the publish, 5 October 2026
Josh, 17:5xZ: "deploy n3 now". Published by the 0.3.9 release engineer with the fee-switch mechanism
(release-0.3.9.md section 10), from the runbook finality-v3-rollout-devnet.md sections 3 and 4, right after every
node carried the fee-switch digest ab8847da.... No new binary: the switch has been in every node since 0.3.4 (the
a24ab01a Mac, Windows and Linux builds all carry finality_v3_activation_daa, checked with strings).
N3 and the digest
N3 = 135,200: DAA 120,755 at 17:57:17Z (the observer's getBlockDagInfo) + 14,400 = 135,155, the next round hundred.
At the publish (17:59:14Z, DAA about 120,800) N3 - DAA = 14,400, over the 10,800 the rule asks. The switch keys on the
checkpoint's DAA score; at 0.965 blocks/s the sink crosses N3 about 22:05Z on 5 October and the first v3
checkpoint follows about a minute later.
The object: {"difficulty_v2_activation_daa":33000,"proving_v0_activation_daa":84100,"fees_v1_activation_daa":210000,"finality_v3_activation_daa":135200}.
Read on a scratch a24ab01a node (17:57:47Z, 22 s, ports 60995/60996):
Calibrated v1 fees from the override file: chain blocks metered with the adopted table, budgets and floors from DAA score 210000
Finality rule v3 from the override file: active from checkpoint DAA score 135200
