What is ₿USD?
₿USD is a USD-pegged stablecoin and the first proposed Treasury-Backed Digital Currency (TBDC). One token equals one dollar. It is issued by a consortium of Bitcoin treasury companies. Each token is backed by Bitcoin held in a two-ledger reserve system, verifiable on the base layer in publicly addressable wallets.
₿USD is not an algorithmic stablecoin. It carries no endogenous token mechanism and makes no market-incentive assumptions. It is not a fiat-backed stablecoin. It holds no dollars, no US Treasuries, and no bank deposits. Its collateral is Bitcoin , the only asset whose supply is fixed by protocol and whose custody requires no counterparty.
The Two-Ledger Reserve System
Each consortium member maintains two Bitcoin ledgers on the base layer. Both hold actual Bitcoin in publicly verifiable wallets. Reserves are not lent, staked, or rehypothecated.
Holds Bitcoin purchased with incoming consumer USD at the moment of minting. Directly backs outstanding tokens. In a rising market, this ledger appreciates faster than the ₿USD redemption obligation it covers, generating surplus.
Holds Bitcoin drawn from each consortium member's existing treasury holdings. Covers redemptions when Ledger 1 is insufficient , i.e. when Bitcoin spot has declined below the acquisition price. The size of Ledger 2 determines the depth of the system's bear market protection.
The issuance process is straightforward. A consumer sends $1,000. The consortium purchases Bitcoin at spot with those funds and deposits it into Ledger 1. One thousand ₿USD tokens are issued. From that moment, the Ledger 1 Bitcoin tracks spot price while the ₿USD liability remains fixed at $1.00 per token. As spot rises above the acquisition price, Ledger 1 generates surplus. As spot falls below it, Ledger 2 covers the gap.
On redemption, the consortium sells the required Bitcoin from Ledger 1 and returns $1,000. The tokens are burned. If Ledger 1 has appreciated, the consortium retains the surplus. If Ledger 1 has fallen below the redemption amount, Ledger 2 covers the difference.
The Conservative Issuance Ceiling
Total ₿USD issuance is capped at the Bitcoin Currency (₿C) denominated value of the consortium's combined Bitcoin holdings, not spot value. This conservative ceiling means the consortium retains significant uncommitted reserves at all times. Individual ₿USD tokens are backed 1:1 at minting: each dollar of incoming fiat purchases Bitcoin at spot, and Ledger 1 holds exactly the obligation. If BTC spot rises after minting, Ledger 1 moves into surplus. If spot falls, Ledger 2 covers the gap.
For the peg to fail, Bitcoin's spot price would need to fall below its own lifetime cumulative average and remain there permanently. That event has no precedent in Bitcoin's history. Every time spot has approached the ₿C level, it has recovered, because sustained spot prices below the historical average imply that Bitcoin's entire market history has been repriced to zero, which is indistinguishable from Bitcoin's terminal failure as an asset.
| BTC Spot | ₿C Price | Issuance Capacity Ratio | System Status |
|---|---|---|---|
| $140,000 | ~$22,000 | ~6.4× headroom | Deep reserve surplus; wide issuance capacity |
| $70,000 (today) | ~$18,700 | ~3.75× headroom | Healthy; substantial uncommitted reserves |
| $35,000 | ~$17,000 | ~2.1× headroom | Issuance tightens; Ledger 2 backstop active |
| $18,700 (= ₿C) | ~$18,700 | ~1.0× | Floor; no historical precedent |
The Virtuous Cycle
Every ₿USD token minted requires the consortium to purchase Bitcoin. Consumer demand for ₿USD is therefore structurally identical to Bitcoin demand. As adoption grows, three things happen simultaneously:
- Incoming USD purchases Bitcoin for Ledger 1, increasing spot demand directly.
- Rising spot price increases the USD value of all consortium holdings, expanding the ₿C-denominated issuance ceiling.
- Fee revenue, reinvested into Bitcoin during the bootstrapping phase, deepens Ledger 2 and further raises the floor.
The consortium commits to a pre-determined fee reinvestment policy: 100% of fee revenue is deployed to purchase additional Bitcoin until the coverage ratio , total Bitcoin holdings valued at ₿C price divided by total ₿USD outstanding , reaches a defined threshold. Above that threshold, fee reinvestment tapers according to a fixed schedule and profits are distributed. The threshold is determined by the coverage ratio formula, not by board discretion.
Circulation and the Currency Layer
The reserve system is designed for the transition phase , the period when consumers still think of ₿USD as "digital dollars" and the option to redeem for USD remains relevant. As adoption deepens, that mental model changes.
When a merchant prices goods in ₿USD, a worker receives a salary in ₿USD, and a lender denominates a loan in ₿USD, redemption pressure approaches zero. Tokens circulate on the currency layer indefinitely. Ledger 1 and Ledger 2 accumulate appreciation without outflow. The coverage ratio compounds continuously.
At sufficient scale, the reserve requirement transitions from a defensive mechanism to an asymptotic certainty. The consortium's Bitcoin holdings, accumulated through years of issuance and fee reinvestment, represent collateral so deep that no plausible bear market threatens the peg. The bridge between fiat and the currency layer remains open , but fewer and fewer people need to cross back.
How ₿USD Compares
| Property | USDT / USDC | Algorithmic | ₿USD |
|---|---|---|---|
| Collateral | Fiat / Treasuries | None / endogenous token | Bitcoin (base layer) |
| Reserves verifiable | Audited periodically | On-chain (no real backing) | On-chain, real-time |
| Peg mechanism | 1:1 fiat backing | Market incentives | Bitcoin on-chain reserves, two-ledger architecture |
| Demand creates | US Treasury demand | Token volatility | Bitcoin demand |
| Holding value over time | Depreciates with USD | Unpredictable | $1.00 redeemable; reserves appreciate |
| Censorship resistance | Accounts can be frozen | Varies | Bitcoin base layer |
| Failure mode | Issuer insolvency / regulation | Reflexive collapse | BTC sustained below $1 per-token reserve , requires >99% Bitcoin decline |
Relationship to ₿C
₿USD is built on Bitcoin Currency (₿C) but is a distinct product. ₿C is a denomination protocol , it requires no issuer, holds no reserves, and makes no promise of redemption. Any wallet or merchant can adopt ₿C independently. ₿USD is an issued monetary instrument with specific institutional participants, reserve requirements, and redemption obligations.
The ₿C price serves as the conservative issuance ceiling: total ₿USD supply cannot exceed the ₿C-denominated value of consortium holdings. This means the consortium retains significant uncommitted reserves at all times, because the ceiling is set at the cumulative average rather than the higher spot price. Individual tokens are backed 1:1 at minting, with Ledger 2 providing the backstop when spot declines below the minting price. The gap between spot and the slowly-moving ₿C floor ensures the system has room to absorb drawdowns before the $1.00 peg is threatened.
