An independent proof-of-work blockchain. Bitcoin Core's consensus engine, RandomX instead of SHA-256, and a difficulty algorithm that retargets every block. No premine, no ICO, no allocation — every coin was mined.
Every figure on this page is checkable, and most are one HTTP request away. Where a number appears, the endpoint that produces it is named. Where something is a weakness, it is in section 10 rather than left out. This document describes what exists, not what is hoped for.
PCoin (ticker PCN) is a Layer-1 blockchain with its own genesis block, network magic, ports, address format and UTXO set. It is not a token, not an ERC-20, not a sidechain, and it does not settle on anyone else's chain.
It is a fork of Bitcoin Core v29.4 with two consensus changes: proof of work is RandomX rather than SHA-256, and difficulty is LWMA rather than the 2016-block retarget. Everything else — the 21 million cap, the 50 PCN block reward, the 210,000-block halving, the 600-second target spacing, the UTXO model, the script system — is Bitcoin's, unchanged.

Bitcoin's economic design is, in our view, close to correct: a hard cap, a predictable emission curve, and issuance paid only to whoever does the work. Its mining design is the part that aged badly. SHA-256 rewards whoever can buy the most specialised silicon, so mining left ordinary hardware within a few years and has not come back.
PCoin keeps the economics and replaces the hash function. RandomX is built so that a general-purpose CPU is close to optimal: it executes a randomly generated program against a large dataset, which is exactly the workload a CPU is designed for and exactly the workload an ASIC cannot specialise away profitably. The result is a chain an ordinary laptop can mine.
That is the entire thesis. There is no novel consensus mechanism here, no new virtual machine, and no claim to have solved a hard problem in distributed systems. PCoin is deliberately conservative: it inherits a codebase that has been attacked continuously since 2009, and changes two things.
Implementation: src/crypto/pow_randomx.cpp. The RandomX key is the
fixed ASCII string PCoin/RandomX/v1 on every network. Rotating that key
would be a hard fork and is treated as one.
Two details matter to anyone integrating:
RandomX(80-byte header) ≤ target, read little-endian. But
block ids, previous-block links and every hash in the RPC and the explorer are still
double-SHA-256, exactly as in Bitcoin. Code that conflates the two
will be wrong.Mining is available three ways: the node's own multithreaded CPU miner
(startmining over RPC), the public pool at
pool.pc.am, and third-party miners —
SRBMiner-Multi 3.5.6+ mines PCoin as algorithm
randompcn.
Bitcoin retargets every 2016 blocks, roughly fortnightly. On a chain with a small and volatile hashrate that is far too slow: a miner arriving with a large rig produces blocks in seconds until the next retarget, and a miner leaving strands the chain at a difficulty nobody can meet.
PCoin uses LWMA — a linearly weighted moving average over a 60-block window — and retargets every block. It activated at height 2800, and the transition happened with no chain split.
Three properties of the implementation are deliberate and documented in the source, because each protects against a specific attack or failure:
Clamps are asymmetric on purpose: difficulty may rise at most 3× per block but fall up to 12×, so the chain recovers quickly when hashrate leaves and cannot be ramped as quickly when it arrives.
Identical to Bitcoin's, deliberately: 50 PCN per block, halving every 210,000 blocks, converging on 21,000,000 PCN. At 600-second spacing the first halving falls roughly four years after genesis.
Supply is computed from the UTXO set, not from height × subsidy. Two consequences, both surprising the first time:
Live figures are machine-readable at
explorer.pc.am/api/supply,
with bare-number endpoints at /api/supply/total,
/api/supply/circulating and /api/supply/max.
There was no distribution event, because there was nothing to distribute. No premine. No ICO or IEO. No private sale, seed round or strategic allocation. No founder, team or advisor allocation. No vesting schedule, because nothing is vesting. No treasury carve-out.
All PCN in existence was produced by mining, block by block, from block 1 onwards — and the block 0 reward is unspendable, as in Bitcoin.
This is not a claim that requires trust. The chain is public and the issuance rule is in the source. Every coin traces to a coinbase transaction; there is no other way for PCN to come into existence. Anyone can walk the chain and check.
Circulating supply therefore equals total supply. There is no locked, reserved or otherwise non-circulating tranche to deduct.

Peer discovery follows Bitcoin's order: peers.dat, then the DNS seed,
then fixed seeds compiled into the node, then addr gossip. A node that
has run before needs no seed at all.
PCN is spendable today. Three independent products accept it and credit the payer automatically once the deposit confirms:
| Service | What it is |
|---|---|
| webai.pc.am | An AI assistant inside the browser: reads the page you are on, works across tabs, fills forms |
| webbuilderbot | A Telegram bot that builds websites |
| aicontrol.pc.am | Remote control and automation platform |
Each issues a permanent per-user pc1q… deposit address, watches
it, and credits the user's balance at the rate published at the moment the deposit
confirms — recording that rate on the transaction so it can be audited later.
None of them holds a private key: the deposit-watching design is custody-free by
construction, which is why a breach of any of those web servers cannot move funds. The
full specification is at docs.pc.am.
A miner can therefore pay for their own AI usage with what their CPU earned, which is the shape of utility we were aiming for: the coin acquired somewhere to be spent before it acquired a market.
PCN is a native coin on its own chain, so it cannot be traded directly on an Ethereum-style decentralised exchange. wPCN is a BEP-20 token on BNB Smart Chain, backed 1:1 by PCN held in a public reserve.
| Property | Value |
|---|---|
| Contract | 0x290A5779a419Cb9cB22fa087CDD1CD16dA2D95F1 |
| Decimals | 8 (not 18) |
| Supply | Fixed, minted once at deployment |
| Privileges | No owner, no mint, no pause, no blacklist, no transfer fee, no proxy |
| Redemption | redeem(), permissionless, at any time |
The contract is verified on BscScan and cannot be changed by anyone, ourselves included. Wrapping is a deposit to the reserve; redeeming burns wPCN and releases the matching PCN. Both directions are public and auditable on their respective chains.
This section exists because a white paper without one is marketing. Everything here is a real weakness of PCoin as it stands today.
Genesis was 1 August 2026. A chain measured in weeks has no track record, and its accumulated proof of work is correspondingly small. Treat it as what it is.
Most of the network's hashrate currently mines through pool.pc.am, which we operate. A pool holding a majority of hashrate could in principle reorganise the chain. We publish the figure rather than obscure it — both the pool's hashrate and the network's are in the pool's public API, so anyone can compute the share at any moment — and an automated monitor alerts on it. But the honest statement is that decentralisation of mining is a goal, not a present fact. More independent miners and more pools is the fix, and anyone is free to run either.
The wPCN/USDT pool on PancakeSwap holds a small amount of liquidity and trades rarely. A modest order moves the price substantially. Nobody should assume they can exit a position of any size at the quoted price.
Neither the consensus changes nor the wPCN contract has been audited by an external firm. The consensus code inherits Bitcoin Core's, which is heavily reviewed, and our own changes are covered by unit tests, a fuzz target and an independent reference implementation of the difficulty algorithm — but that is our testing, not an independent audit. An audit of the wPCN contract is on the roadmap.
The DNS seed and the fixed seeds compiled into the node are ours. If all of them disappeared, existing nodes would keep running and mining — they remember their peers — but new nodes would struggle to find the network without being handed a peer address manually. Community-run seeds are the fix, and they are the first item on the roadmap.
Blocks 2016–2799 were produced under a difficulty calculation that overflows.
Every node computed the same wrong answer, so consensus held, and those blocks are
valid only under that arithmetic. Correcting it would orphan real work, so the legacy
path is deliberately preserved and documented in the source; new blocks use the
checked LWMA path. We mention it because anyone auditing src/pow.cpp will
find it, and should know that we know.
Dates are commitments, so they are kept deliberately few. Anything not listed here is not promised.
