What is BitcoinPurple?

Bitcoin, rebuilt
with 15 years
of lessons.

BitcoinPurple is a peer-to-peer cryptocurrency built on the same code as Bitcoin — the most tested and secure in the history of cryptocurrencies — with three key differences.

01

Bitcoin-proven codebase

A direct fork of Bitcoin Core — the most audited financial software in history, with 15 years of real-world use and hundreds of billions at stake.

02

Fair launch, no premine

No coins were pre-allocated to founders or investors. Every BTCP in existence was mined by someone providing real computational work.

03

You hold your keys

Peer-to-peer and censorship-resistant by design. No central authority can freeze, reverse, or confiscate your funds.

No premine.  No privileged founder.  Just open code and independent nodes.

Whitepaper

The protocol,
in detail.

Protocol architecture, consensus algorithm, emission schedule, and design rationale — fully documented in the BitcoinPurple technical whitepaper.

Technology

Built on proven foundations.
Upgraded for the future.

BTCP inherits Bitcoin's battle-tested architecture with three key improvements active from block 0 — no legacy to manage, no scheduled upgrades to wait for.

SHA-256d Mining

BitcoinPurple uses the same mining algorithm as Bitcoin (SHA-256d). Any ASIC hardware that mines Bitcoin can also mine BTCP.

Difficulty is recalculated every 120 blocks (~2 hours) to maintain the target of one block per minute — no drift over time.

Security

Built to last.
Designed to be verified.

Bitcoin Core foundation

A direct fork of Bitcoin Core — the most reviewed financial software in history, with 15+ years of real-world use and billions at stake.

MIT License

Every line of code is public. Anyone can read it, verify it, improve it, or build on top of it. No hidden algorithms, no secret backdoors.

Reproducible builds

Distributed binaries can be independently verified from source. Same source always produces the same binary.

Minimal attack surface

No node-side executable smart contracts. The scripting language is intentionally limited to Bitcoin's proven model.

Found a security issue? Open a report at GitHub Issues. Do not disclose publicly until a patch is available.

For Developers

JSON-RPC compatible
with Bitcoin Core.

Any Bitcoin Core library works — change the port and address prefixes. Drop-in compatible for exchanges and wallet integrators.
