Proposal: derive the UNL from Task Node identity and ratify it through Cobalt

Validator lists on public ledgers are bought with grants and market-development fees. Post Fiat should instead derive its validator list deterministically from Task Node identity: a proven wallet, a replayable work history, and a public vouch graph. This proposal grounds that in the existing Admission Policy V1, the Task Node ledger replay, and the Cobalt ratification path, and evaluates World ID against a Task Node social graph for one-person-one-seat.

Arc/current-main H100 replay: historical proof passes, current merge remains gated

An H100 replay confirmed the archived Arc v1 Groth16 pipeline and reproduced its public values byte for byte, but the current v2 guest correctly rejects that old witness and Arc’s public RPC cannot supply the authenticated registry proof needed to recapture it. PR 37 remains unmerged.

pfUSDC on Arc: one USDC, there and back, authorized by proofs of both chains' finality

On 2 September 2026 we deposited 1.000000 USDC into a vault on Arc testnet, proved Arc’s validator quorum finalized it inside a Groth16 proof, minted pfUSDC on the PostFiat L1 against that proof, burned it, proved PostFiat finality of the burn under ML-DSA signatures in SP1, and released the USDC on Arc against that proof. Every hop is pinned to its hash and evidence file, 32 corrupted witnesses were rejected, and the one open finding (the SP1 gateway owner key) is stated up front with a reproducible PoC.

Runbook: Deterministic Qwen 3.8 Inference for Replayable Index Scoring

The locked serving profile that makes Qwen 3.8 27B FP8 produce byte-identical output across independent H200 hosts: exact model pin, runtime image digest, SGLang launch flags, fixed-batch request discipline, and the two-host replay gate that verifies every raw response byte for byte.

Trustless Wrapped Stablecoins on PFTL

A primer and technical specification for wrapping external stablecoins onto PFTL under consensus-enforced verification: user-initiated deposits into an on-chain vault, an evidence ceremony every validator checks, quorum-observed credits, challenge-windowed exits, a per-tier threat model, and a staged ladder from observed verification to full finality proofs.

Private NAV Swaps, Explained From Zero: What the Product Is and How It Becomes Real

A ground-up explainer of the private NAV swap product: what wrapped pfUSDC actually is, how NAVCoins are priced on PFTL and represented on Uniswap, what a transparent and a private transaction look like step by step, how the counterfeit problem was found and fixed, why Orchard transactions need warm-ups, how RFQ quoting fits a wallet, how NAV and TVL move when money subscribes, and an honest ledger of what is and is not implemented.
