PCoin (PCN) — the coin anyone can mine

PCoin is an independent Layer-1 blockchain — a fork of Bitcoin Core v29.4 with three consensus changes: proof-of-work is RandomX, the CPU-fair algorithm, so an ordinary phone or laptop is a first-class miner; difficulty is LWMA, retargeting every block from height 2800; and the future-block-time limit tightens from 2 hours to 15 minutes at and above that height. No ASIC farms, no premine, no investors.

The mission

Money creation for ordinary people. If you own a phone or a laptop, you can mine PCN.

1. Fair by physics. RandomX (the Monero PoW algorithm) makes general-purpose CPUs the best miners, neutralizing ASICs and mostly neutralizing GPUs.
2. Proven, boring economics. Bitcoin's monetary rules, untouched: 21 million cap, halvings, 10-minute blocks. Nothing clever, nothing new to break.
3. Community from zero. Every node is equal. There is no premine and no company; the founder's role dissolves as the network grows.

Key parameters

Parameter	Value
Ticker	PCN
Launch	August 2026
Consensus	Proof-of-work: RandomX, fixed key PCoin/RandomX/v1, light-mode (256 MB) verification; block IDs remain double-SHA256
Supply	21,000,000 PCN — 50 PCN subsidy, halving every 210,000 blocks
Blocks	10-minute target, LWMA difficulty retarget every block from height 2800 (the legacy 2016-block retarget applies only below that height)
Mainnet ports	P2P 9444, RPC 9443
Network magic	cf a2 d1 b8
Addresses	legacy start with P (base58 prefix 55); bech32 pc1...
Genesis	block ID a95d51f0cbf25cad10c35961c6189356525d079835f02e83e2395f382fbe264a, time 1785600628, nBits 0x1f0fffff (~4096 hashes/block at launch)
Config / data	pcoin.conf in ~/.pcoin (Linux) or %LOCALAPPDATA%\PCoin (Windows)
Seed nodes	seed.pc.am (static DNS seed, several addresses) and dnsseed.pc.am (crawler-backed DNS seed), plus compiled-in fixed seeds in src/chainparamsseeds.h

PCoin is not a token and does not run on any other chain. It has its own genesis block, network magic, ports, and address formats — a PCoin node can never connect to or sync from the Bitcoin network.

Quickstart (Linux)

1. Get binaries. Linux one-liner (verifies the download against the release's SHA256SUMS, installs, and runs the setup wizard): curl -fsSL https://pc.am/dl/install.sh | sudo sh. Windows, Android and plain archives: https://pc.am/download. Or build from source — see PCOIN.md. Binaries keep their upstream names (bitcoind, bitcoin-cli).

2. Run a node. It auto-connects to the network via seed.pc.am:

mkdir -p ~/.pcoin
printf 'server=1\nrpcuser=pcoinrpc\nrpcpassword=CHANGE_ME_long_random\n' > ~/.pcoin/pcoin.conf
./bitcoind -daemon
./bitcoin-cli getblockchaininfo   # genesis: a95d51f0cbf25cad...264a

3. Mine. The built-in miner is all you need. (If you already run mining software: SRBMiner-Multi ≥ 3.5.6 mines PCN natively against the pool with --algorithm randompcn --pool pool.pc.am:3333; stock xmrig does not work — it speaks Monero's protocols — see contrib/pool/MINER-INTEGRATION.md §9.)

./bitcoin-cli createwallet "main"
ADDR=$(./bitcoin-cli getnewaddress)
./bitcoin-cli startpoolmining "pool.pc.am:3333" "$ADDR" 0   # 0 = all cores
# or solo, all cores: ./bitcoin-cli startmining "$ADDR" 0
# status either way:  ./bitcoin-cli getcpuminerinfo

Difficulty now tracks the whole network's CPUs (LWMA, every block since height 2800), so a single CPU mining solo sees a block only every few days or longer. For a steady share use the pool — it pays in the coinbase, and the fee is shown on https://pool.pc.am. Rewards mature after 100 confirmations (bitcoin-cli getbalance).

Roadmap (near term)

• Android node + miner app shipped — https://pc.am/download
• First real-world micro-payments services accept PCN today — https://docs.pc.am
• 100 independent nodes
• Community-run seed nodes
• In-browser wallet

Honest disclosures

PCoin is a young, experimental chain — it is not an investment. A small, thin market exists (https://price.pc.am posts the rate the payment rails use; wPCN trades on PancakeSwap via https://wrapdesk.pc.am) and any price can be moved by one party. Like any small PoW network, its security grows with the number of independent participants; with few miners, a 51% attack is cheap. There is no premine and no sale, but the founder's own machines mined a large share of the early supply. The distribution is public and checkable at any time at https://explorer.pc.am/api/addresses/top — read that, not this sentence. The entire source is public and MIT-licensed — audit it yourself.
