A Community Proof-of-Stake Cryptocurrency with Native Solana Bridge
420M supply • 1% staking APR • Solana DEX liquidity • Built for the cannabis community
PotCoin is a Proof-of-Stake cryptocurrency purpose-built for the cannabis industry. Operating on a Bitcoin-derived codebase (Bitcoin → Peercoin → NovaCoin → MotaCoin → PotCoin), it combines a 420,000,000 fixed supply, 1% annual staking rewards, and a bidirectional escrow bridge to Solana for instant DEX liquidity.
The bridge architecture uses pre-funded escrow wallets on both chains — not mint/burn — so the total supply is always verifiable and can never exceed the 420M hard cap. Users buy POT on Solana DEXes and bridge to the mainchain for staking rewards, or bridge back for trading.
PotCoin ships 28 custom RPC commands for staking management, bridge operations, coin control, and chain analytics — all accessible from the daemon CLI.

- 1% APR Proof-of-Stake — pure PoS after block 500, with stake split/combine automation, stake-for-charity auto-donations, and HyperStake kernel derivation
- Solana bridge built into the daemon —
bridgetosol <amount> <solana_address>sends POT to Solana directly from the CLI, usingOP_RETURNon-chain routing data (no external APIs in the transaction path) - Static supply escrow — the 380M premine is pre-distributed across 1,374 escrow UTXOs in graduated tiers; no minting, no burning, total supply always = 420M
- Tor-routed staking — P2P traffic can be routed through Tor (
proxy=127.0.0.1:9050) for IP privacy on staking nodes - 28 custom RPCs — staking management, bridge operations, coin control, chain analytics, wallet utilities (see RPC Reference)
- Deterministic multi-platform Guix builds — x86_64-linux, arm-linux, aarch64-linux, Windows (mingw), macOS (x86_64 and arm64)
PotCoin uses the standard Bitcoin-Core-derived autotools + Guix build system.
git clone https://github.com/<owner>/potcoin-core.git
cd potcoin-core
./contrib/guix/guix-buildThis builds all 6 target platforms deterministically. Artifacts land in guix-build-<commit>/output/<host>/. Each platform tarball contains both potcoind and potcoin-qt.
To build only one platform (e.g., x86_64-linux):
HOSTS="x86_64-linux-gnu" ./contrib/guix/guix-buildRequirements: Guix 1.4+ installed, ~40 GB disk for depends cache, 2-6 hours for full multi-platform build.
See BUILD_NOTES.md for a gotcha to be aware of after project renames.

potcoind helppotcoin-qt &The GUI exposes a Bridge tab for moving POT between the mainchain and Solana without touching the CLI. Full wallet features include staking controls, coin control, stake-for-charity configuration, and the integrated block explorer.
The daemon automatically discovers peers via DNS seeds (seeds.potcoin.com) and syncs the chain. Expect ~1-2 hours for a full initial block download depending on bandwidth.
PotCoin's bridge is chain-native — all routing data is embedded on the blockchain using OP_RETURN outputs. No external APIs, no centralized servers in the transaction path. Bridge instructions live permanently on both chains and are fully auditable.
potcoind bridgetosol 1000 "7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU"This sends 1000 POT to the bridge escrow with an OP_RETURN containing your Solana address. After 10 confirmations on PotCoin, the bridge service releases the equivalent SPL tokens to your Solana wallet.
potcoind bridgestatus # list all your bridge transactions
potcoind bridgestatus <txid> # details for a specific bridge TXSend SPL POT to the bridge escrow ATA on Solana with a Memo instruction containing your PotCoin address (starts with P). After 30 Solana confirmations, the bridge sends the equivalent native POT to your mainchain address.
See the Whitepaper §4 for the full architecture including UTXO tier selection, security properties, and escrow distribution.
PotCoin ships 28 custom RPCs beyond the standard Bitcoin set.

- Hybrid PoW/PoS bootstrap — blocks 1-500 are Proof-of-Work (X13 hashing, 15-minute target difficulty retarget); block 501 onward is pure Proof-of-Stake
- HyperStake-derived PoS kernel — stake hash depends on
nStakeModifier, block time, prev output, and UTXO age; must satisfyhash < target × coin-day-weight - Staking parameters — 15 min minimum age, 25 day max age, 10 block coinbase maturity, 260s block time target
- Automatic UTXO management — stake split above threshold (default 250 POT), combined stake outputs capped at 2,500 POT (Max Combine)
Block 1 mints 380,000,000 POT as the bridge escrow premine. The remaining 40,000,000 exists as the Solana SPL token reserve. Staking adds ~1% annually; the 420M hard cap is enforced in consensus via MAX_MONEY. The 0.420 POT minimum fee creates mild deflationary pressure.

Pull requests welcome. Please:
- Fork and work on a feature branch
- Match the existing code style (Bitcoin-era conventions)
- Include test coverage where practical
- Describe the change clearly in the PR body
Consensus-critical code (anything in src/main.cpp affecting block/tx validation, src/kernel.cpp stake rules, src/chainparams.cpp parameters) needs exceptionally careful review.
