Since 2026-09-11 chain 2800 has ten validators (f=3, commit quorum 7 of 10), all still operated by the Foundation, one of them running the second, Nethermind-derived client. Since 2026-09-04 the anchor certificate is scheme-tagged and carries Falcon-512 seals, with SLH-DSA-SHA2-128s seals as well at every anchor until block 20,746,736 and at every 128th block since; from block 17,225,968 (2026-09-05) to block 20,746,736 there was one anchor every 128 blocks with at least six valid seals for each scheme, and since then (AIP-22 stages 1 and 2, updated 2026-09-30) a Falcon-512 certificate is required every 32 blocks and SLH-DSA seals every 128, with at least seven valid seals for each scheme, as many as the quorum of the ten validators (below block 24,148,752 the seals proved those validators signed the block, not that it was decided, per the AIP-22 erratum of 2026-10-01, and from that block a certificate that carries the quorum of one round proves the decision; this clause corrected on 2026-10-25), from block 20,715,632; since block 20,836,228 the validators are named in consensus by post-quantum ids.

-- Consensus on chain 2800 is QBFT at N = 10 (seven validators until 2026-08-09, nine until 2026-09-11): anchor blocks carry a post-quantum certificate under their hash since block 13,014,000, and since block 24,300,000 (AIP-22 stage 4) every validator attributes a consensus vote only through its verified post-quantum seal (headers are still admitted on their ECDSA commit seals until AIP-22 stage 5). Aere never claims post-quantum consensus. Post-quantum also applies to signatures, accounts and applications.
+- Consensus on chain 2800 is QBFT at N = 10 (seven validators until 2026-08-09, nine until 2026-09-11): anchor blocks carry a post-quantum certificate under their hash since block 13,014,000; since block 25,080,000 (AIP-22 stage 5) its headers no longer carry ECDSA commit seals and, since block 24,300,000 (AIP-22 stage 4), every vote counts only with the verified post-quantum seal of its author, and a commit still carries the ECDSA commit seal of its validator as an additional check. Aere calls that post-quantum consensus and never claims it without its limits: the transport between nodes is still authenticated by secp256k1, the ten validators are run by one operator, and no third party has audited it yet. Post-quantum also applies to signatures, accounts and applications.
