About Post Fiat
Post Fiat is XRP 2.0: a private, quantum-resistant Layer 1 for on-chain capital markets. Machine intelligence will compound capital on chain. Post Fiat is the chain where that will happen.
It is built so that you can privately swap any asset on chain at low cost and hold market-neutral portfolios as NAVCoins whose net asset value is proven on chain, on a fixed-supply native asset, with Task Node as its network of pseudonymous contributors.
What it does
- Represents portfolios trustlessly. A NAVCoin is a floating-value unit issued only against a finalized, proven NAV.
- Swaps into them privately. Asset-Orchard settles both legs of an exchange in one atomic, shielded transition.
- Maintains a fixed supply. Native PFT is fixed at genesis; every fee burns; there is no validator reward.
- Runs an information network. Task Node assigns, verifies and rewards useful work by pseudonymous contributors and their agents.
How it differs from XRP
| XRP Ledger | Post Fiat | |
|---|---|---|
| Validator trust | Published list file | Protocol state, ratified by Cobalt |
| Signatures | Classical | ML-DSA-65, post-quantum, from genesis |
| Settlement | Transparent | Private atomic swaps (Asset-Orchard) |
| Instruments | Issued tokens | NAVCoins with proven reserves |
| Native supply | Fixed, fees burn | Fixed, fees burn |
| First market | Payments | Buy-side capital markets |

FAQ
What is a NAVCoin?
A floating-value unit whose reserve valuation, supply, methodology, custody perimeter and settlement representation can each be inspected. The ledger creates and retires units only against a finalized, proven NAV. NAV floats with the reserves.
What is the Task Node?
The community intelligence layer: contributors and their AI agents request tasks, submit evidence, are verified and earn PFT. It is the main way to take part in the network today.
What is PFT used for?
PFT is the fixed-supply native asset. It pays for ordering and proof verification, every fee burns, and it rewards verified Task Node work.
