purple-data

Technical reference for building infrastructure on top of BitcoinPurple (BTCP) — a Bitcoin fork with 1-minute blocks and a 1,000,000 BTCP supply cap.

Contents

technical-data.md is the single source of truth for all chain-specific constants, sourced directly from the BTCP codebase. It covers:

• Network parameters — ports, magic bytes, address prefixes, HD key version bytes, genesis hashes for mainnet, testnet, signet, and regtest
• Consensus rules — block time, halving schedule, difficulty retarget (every 120 blocks), soft-fork activation heights
• ElectrumX — coins_btcp.py coin class, Docker patch snippet, environment variables
• Electrum wallet — constants.py class definitions, derivation paths, checkpoints format, header verification logic
• Lightning Network — chain_hash values, BOLT11 HRP, block-time-scaled timeout parameters (×10 vs Bitcoin), CLN and LND fork notes
• bitcoinpurple.conf — full annotated node configuration

Quick orientation

Parameter	Mainnet	Testnet
P2P port	13496	23496
RPC port	13495	23495
ElectrumX TCP / SSL	50001 / 50002	60001 / 60002
Bech32 HRP	btcp	tbtcp
BOLT11 prefix	lnbtcp…	lntbtcp…
Block time	60 s	60 s
Halving interval	500,000 blocks	—
Max supply	1,000,000 BTCP	—

Lightning note: BTCP has 1-minute blocks. All LN timeout values expressed in blocks must be multiplied by ×10 compared to Bitcoin defaults (e.g. to_self_delay 144 → 1440, cltv_expiry_delta 40 → 400).
