Discussion draft: a fourteen-scene immersive presentation explaining Post Fiat, PF Terminal, Task Node, NAVCoins, private foreign exchange, replayable AI governance, Cobalt, and two possible No Limit Holdings transaction structures.
What Post Fiat is, explained by contrast: zero-issuance economics, protocol-state governance, and shielded settlement, set against the XRP Ledger and the Canton Network — and the economic bet behind each design.
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.
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.
A research architecture for low-latency Post Fiat applications: FastPay for settlement, wallet-authenticated FastDB for realtime state, Post Fiat data ontology for durable replay, and asynchronous IPFS pinning for archival payloads.
A plain-English explanation of the correct NAVCoin transaction architecture: PFTL as the source of truth, proof-of-reserves epochs, USDC bridge-in, private Orchard swaps, atomic handoff to Uniswap-side a651, and the gates that keep supply honest.
A research design spec for moving NAVCoin supply between PFTL and an Ethereum Uniswap venue without inventory fronting: burn/lock on one side, verify finality, mint/unlock on the other, then optionally execute through Uniswap.
A devnet report on Post Fiat’s transparent and shielded NAVCoin swap demos: what happened, what PFTL checks, what Orchard hides, and what remains self-published.
A click-through visual primer for the shielding, private swap, certification, private egress, redemption, and transparent control steps behind the Private OTC Swaps post.
A grounded technical look at the devnet-proven, code-reviewed Halo2 circuit behind Post Fiat’s shielded NAVCoin swaps: every major constraint, the measured CPU prover bottleneck, the K=15/key-cache optimization sprint, and the remaining path to GPU-accelerated proving.
