Keccak-256d Proof-of-Work
Keccak won the NIST SHA-3 competition. Simple, auditable, no hidden complexity. Mines on CPU and GPU — anyone with commodity hardware can participate.
v0.1.0 — Keccak-256d era
Open-source cryptocurrency
secured by Keccak-256d.
FlowCoin is a Proof-of-Work cryptocurrency using Keccak-256d — a proven, auditable hash from the SHA-3 family. CPU and GPU mining. No premine. No ICO.

Why FlowCoin
Bitcoin's monetary policy. Keccak-256d proof-of-work. Modern cryptography.
Bitcoin's monetary policy
21 million total supply. Halving every 210,000 blocks. 10-minute target. Exactly the same economic properties that made Bitcoin work — just more accessible mining.
Bitcoin-compatible tooling
Wire-compatible P2P. Bitcoin-Core-style JSON-RPC. Cookie auth. Same command-line patterns. If a tool works with bitcoind, it likely works with flowcoind.
No premine, no ICO
Every single FLC is mined from genesis on. No developer tax, no treasury, no venture allocation. The only way to get coins is to mine them or receive them.
Modern cryptography
Ed25519 signatures (RFC 8032). keccak256d block IDs and merkle roots. Real Bech32 v0 addresses — structurally identical to Bitcoin P2WPKH, just with the fl prefix.
Audit-friendly codebase
Vendored dependencies, no hidden magic. 500K+ lines of C/C++20. 55 assert-based test groups covering consensus, crypto, network, wallet. Reproducible builds.
Start mining in three commands
On a typical Linux box — no pool, no account, no registration.
# Install build deps (Ubuntu / Debian)
$ sudo apt install -y build-essential cmake git
# Build FlowCoin
$ git clone https://github.com/KristianPilatovich/flowcoin.git
$ cd flowcoin && cmake -B build -DCMAKE_BUILD_TYPE=Release
$ cmake --build build -j$(nproc)
# Start node + miner
$ ./build/flowcoind -daemon
$ ./build/flowcoin-miner --cookie ~/.flowcoin/.cookieFull mining guide: Documentation → Mining. Benchmarks and hardware tables in the mining doc.
