Bitcoin → proof/btc · registry v1

Bitcoin goes in.
Proof comes out.

proof/btc is a Solana asset whose supply can only be created through irreversible Bitcoin burns verified from Bitcoin mainnet.

There is no Bitcoin inside proof/btc.

When BTC is used to create proof/btc, it is sent to a provably unspendable Bitcoin output.

  • — it cannot be withdrawn
  • — it cannot be redeemed
  • — it cannot be recovered

The confirmed Bitcoin transaction itself becomes the issuance event.

Issuance gets harder.

The conversion rate decreases as cumulative BTC burn increases. Early Bitcoin burns create more proof/btc. Later burns create progressively less.

There is no administrator changing issuance. The curve is deterministic.

Bitcoin determines what happened.
Solana determines what can happen next.

  • — correct burn destination
  • — required BTC amount
  • — Bitcoin block inclusion
  • — transaction ordering
  • — confirmation depth
  • — event has not previously been consumed

Don't trust the registry.
Rebuild it.

Every proof/btc state transition is deterministic. Anyone can start from the protocol genesis block, scan Bitcoin for valid burn events, execute the issuance rules, and independently derive the current registry state.

View Verification Specification
proofbtc · verifier
▌

Verification without trust.

A prover follows Bitcoin and produces evidence showing that:

  • ·the transaction exists
  • ·it is included in Bitcoin history
  • ·the output satisfies burn rules
  • ·the issuance calculation is correct
  • ·the resulting state transition matches the deterministic protocol rules

Solana verifies the resulting proof before accepting issuance.

What proof/btc is not

NOT WRAPPED BTC

No BTC custody account corresponds to individual tokens.

NOT A BRIDGE

BTC does not cross from Bitcoin to Solana.

NOT A STABLECOIN

proof/btc has no 1:1 redemption relationship with Bitcoin.

Bitcoin is the production cost.
Not the collateral.

ELECTRICITY→BTC
BTC→PROOF/BTC

Bitcoin mining converts external resources into BTC. proof/btc issuance converts BTC scarcity into a new asset by permanently removing BTC from circulation.
