v0.3.1 - Seed Node LiveMaximum Supply
Block Reward
Block Time
Double Hash
Built from the ground up with security, decentralization, and transparency at its core.
Built with secp256k1 ECDSA signatures, Double SHA-256 hashing, and Proof of Work consensus. Same cryptographic standards as Bitcoin.
24/7 seed node running on DigitalOcean. Start your node and automatically connect to the CPH network. No central authority.
Only 21 million CPH will ever exist. With halving every 210,000 blocks, CPH Coin is designed to be deflationary.
Fully open-source codebase. Anyone can review, contribute, and build on top of CPH Coin.
Start mining CPH Coin with your computer. Proof of Work ensures fair distribution of coins to miners.
Built-in web block explorer to view all blocks, transactions, and addresses on the CPH blockchain.
Start using CPH Coin in minutes. No account required.
Download CPH Coin from our GitHub releases. Available for Windows and Linux.
Run CPH Coin and use createwallet to generate your ECDSA keys and CPH address.
Use startnode to connect to the live CPH network via our seed node automatically.
