OBTC protocol / public source

Organic Bitcoin (OBTC)

Bitcoin made digital scarcity possible. OBTC asks whether digital scarcity can remain sustainable over centuries. Through UTXO lifecycle management, renewal, and REAP, it keeps monetary ownership active, funds the long-term PoW security budget, and makes the cost of permanent state explicit.

Repositories

Start with the implementation.

These are the main public references for protocol review, node operation, wallet review, and testnet reproduction. Limited reviewer onboarding is available by invitation, with manual test coin issuance and no public faucet.

Protocol surface

The core change is narrow and explicit.

OBTC keeps the UTXO model, then adds lifecycle rules and wallet-facing renewal machinery so dormant state, ownership activity, and PoW security-budget support are handled explicitly.

01

Create

A UTXO is created and receives an expiry height derived from its creation height.

02

Move or renew

The holder can spend or renew before expiry; the active path remains explicit.

03

Expire

After the window, ordinary spending closes and the output becomes a REAP candidate.

04

Reclaim

REAP processes expired outputs under deterministic ordering, input caps, and accounting rules.
