Bitflash (BTF) v0.1 ALPHA
=========================
A revival of Satoshi Nakamoto's original Bitcoin v0.1 client (2009), ported to
a modern toolchain and turned into its own Layer 1 network.
Philosophy: fair launch, no pre-mine, no ICO. One CPU, one vote.
Based on code Copyright (c) 2009 Satoshi Nakamoto.
Copyright (c) 2026 The Bitflash developers.
Distributed under the MIT/X11 software license, see the accompanying
file license.txt or http://www.opensource.org/licenses/mit-license.php.
This product includes software developed by the OpenSSL Project.
Differences from the original Bitcoin
-------------------------------------
- Own genesis block (22/Jul/2026 headline, independent chain)
- Own magic bytes (0xbf 0x1a 0x5c 0xfd) and P2P port 8433
- Addresses start with "B" (ADDRESSVERSION = 25)
- Consensus fixes applied: value overflow (CVE-2010-5139), duplicate inputs,
money range checks (MoneyRange)
- IRC peer discovery replaced by Nostr relay discovery
- Memory-hard Proof of Work (RandomX, CPU + RAM) instead of SHA-256d
- Economics identical to Bitcoin: 50 BTF/block, halving every 210,000 blocks,
21 million total
Build (Windows, MSYS2 UCRT64)
-----------------------------
Modern toolchain:
g++ 16 (MinGW-w64 UCRT), wxWidgets 3.2, OpenSSL 3, Berkeley DB 6, Boost,
libsecp256k1 (Schnorr), nlohmann/json, RandomX
Bundled dependencies are built from source into ../deps and ../RandomX.
In the MSYS2 UCRT64 shell:
bash build.sh (uses src/makefile.mingw)
The resulting executable is src/bitflash.exe.
Command-line options (in addition to the original ones)
-------------------------------------------------------
/port=N listen on P2P port N (default 8433)
/solomine mine without requiring a connected peer (local testing)
/operator operator mode (run pool server)
/participant=ADDR
participant mode; mine to pool .btf address ADDR
/poolname=NAME operator announcement pool name
/poolfee=PCT operator announcement fee percent (example: 0.75)
/pooldashboard=URL
operator announcement dashboard URL
/connectbtf=ADDR
keep an outbound .btf connection to ADDR
/rvrelay=HOST:PORT
override meeting relay list with one relay
/announcerelay=HOST:PORT
announce this relay on Nostr for discovery
Roadmap
