Organic Bitcoin
A Bitcoin-derived lifecycle-money experiment for technical review.
OBTC explores expiry, renewal, and rule-bound reclaim in a Bitcoin-derived UTXO system. Active users can renew; long-dormant value can enter a deterministic reclaim path that preserves a refund share and contributes to the security budget.
Independent chain. Not Bitcoin. Not a production financial network. Not investment advice.
Safety notice
OBTC is not for sale on this website.There is no presale, no public faucet, no exchange listing claim, no yield claim, and no instruction to import Bitcoin private keys.
What OBTC explores
Expiry, renewal, and rule-bound reclaim.
OBTC is a Bitcoin-derived lifecycle-money experiment that makes long-term dormancy explicit through expiry, renewal, and rule-bound reclaim.
It asks whether a Bitcoin-like UTXO system should treat very long dormancy as first-class protocol state. Active users can renew; abandoned value can eventually enter a deterministic reclaim path that preserves a refund share and contributes to the security budget. The current materials are for developers, node operators, miners, and auditors, not for production financial use.
Review surfaces
Start with implementation surfaces that can be inspected.
These are the main public references for protocol review, node operation, wallet review, and testnet reproduction. The canonical public testnet self-test entry is available, with manual test coin issuance and no public faucet.
Wallet and renewal review
Wallet implementation: network selection, expiry inspection, manual renewal, batch renewal, auto-renew scheduling, and wallet automation surfaces.
github.com/organicbitcoin/obtcwalletProtocol parameters under review
Shown for reviewer context, not as a production launch promise.
These values are provisional mainnet-candidate materials. They are not a production launch promise, claim window, income promise, or invitation to move funds.
Lifecycle horizon
7 years by block height under the current mainnet-candidate window.
Expiry handling
70% returned to the original script, 30% counted as ReapTax under the current accounting rule.
Selection
Deterministic REAP order with per-block caps and consensus validation.
Replay protection
Separate chain identity and address domain; current status is mainnet-candidate / technical review.
Reading
Use the review path before treating any claim or wallet flow as operational.
