⚠️ Upgrade before block 2800
PCoin switches to per-block LWMA difficulty at height 2800. Right now the chain is at 2585 — about 215 blocks, roughly 26 hours away.
What happens if you don't upgrade
A node older than v1.2.0 will reject the new blocks and quietly carry on mining a branch of its own. It will look completely healthy: hashrate normal, block count rising, balance growing. But nobody else is on that branch, and when you eventually upgrade, everything mined after 2800 disappears.
Coins you have already mined are safe either way.
Check your version — properly
Do not trust the version the node reports. Every build prints the same string, so it will look fine whether you are up to date or not. Hash the binary instead:
Linux

Windows (PowerShell)

If it does not match
Update from https://pc.am — it takes about a minute and needs no resync.

PCN is now accepted by four live services
You can spend mined PCN today, not eventually:
• AI Control — an agent that operates your Windows PCs and Android phones
• 3dmodels.pc.am — ready-to-use 3D models
• checker.pc.am — gift-card balance checking
• @MyWebsiteBuilderBot — describe a site and it builds and hosts it
Each one issues you an address that only your account is credited for. Deposits credit automatically after 6 confirmations, at the rate published on price.pc.am — and every deposit is verified against two independent block explorers before any balance moves. If they disagree, it is held rather than credited.

AI Control — where to find it
The first of the four services in the previous post is at https://aicontrol.pc.am
It runs Claude-powered agents on your Windows PCs and Android phones, and accepts PCN for balance top-ups — so the same phone that mines can pay for what it uses.

⛏ The PCoin mining pool is open.
Until now mining PCN meant solo: you find a whole 50 PCN block, or you find nothing, and a small CPU can wait days between wins. The pool pays you for the work you actually did.
Connect:
pool.pc.am:3333
The part worth understanding: you are paid directly out of the coinbase of every block the pool finds. There is no pool wallet, no private key on the server, no withdrawal to request and no balance an operator could disappear with. The chain pays you, not us.
• PPLNS, 2% fee taken off the block reward
• Minimum payout 0.00000294 PCN — the network dust limit, not a threshold we invented
• Your login is your payout address. No registration, no account
• Needs v1.3.0 or newer — both the node and bitcoin-cli
Live stats and the exact command for your OS: https://pool.pc.am
Two honest notes. A pool does not increase your earnings — it reduces variance, and after the fee you earn slightly less on average than solo. And PCN is still not traded on any exchange, so there is no price; treat it as worth nothing until a real market exists. Solo mining keeps working exactly as before if you prefer it.

The PCoin mining pool is open
Mining alone is a lottery. Your computer either finds a whole block and earns the full 50 PCN, or it finds nothing — there is no partial credit, and a typical PC can wait days between wins. Most people install a miner, see zero for a week, and conclude it is broken.
The pool fixes that. You are paid for the work you did, whether or not you were the lucky one.
HOW TO JOIN — no new software
Pool mining is built into the PCoin node itself, from v1.3.0. One line:
pcoin-cli startpoolmining "pool.pc.am:3333" "<your pc1q… address>" 0
0 means every core. On Windows use bitcoin-cli.exe the same way.
One thing to get right: that command does not survive a restart on its own. Both the Windows tray and the Linux service re-issue SOLO mining when they start, so unless you also add the pool to your miner config, your machine quietly goes back to paying its own address after the next reboot. The one line to add is on the website.
Full instructions: https://pc.am/#pool
HOW IT PAYS
You are paid as an output of the block you helped find. The pool never holds your coins — there is no wallet on the pool, no withdrawal to request, and no balance an operator could walk away with. The chain pays you directly, every block, automatically.
• PPLNS, weighted by how hard each share was, so timing your arrival gains nothing
• 2% fee, taken off the block reward, never off coins already paid to you
• no minimum payout beyond the network dust limit
A freshly mined reward cannot be spent by anyone — pool or solo — until it is 100 blocks deep, roughly 17 hours. That is a rule of the chain, not a delay the pool invents.
BEING HONEST ABOUT IT
A pool does not increase your earnings. It reduces variance, and after the fee you earn slightly less on average than mining alone. What you are buying is predictability.
It also concentrates hashrate, which on a network this small is a real risk rather than a theoretical one. We publish the pool hashrate and the network hashrate at https://pool.pc.am/api/pools so its share is checkable rather than claimed — and we would rather see a second pool run by somebody else than grow this one.
Solo mining is unchanged and still fully supported. If you are large enough to find blocks regularly, it is the better choice — and it is what keeps deciding which transactions go into blocks spread across many hands.

PCoin v1.3.6 - Windows fast mode fix
If you turned on fast mode in the Windows miner, your PC has almost certainly not been mining.
Turning fast mode on stopped the miner app being able to talk to its own node. The node itself kept running perfectly - but nothing was mined, and the Start and Stop buttons stopped working too, so a machine that was already mining could not be switched off either.
You are affected if the app says the node is not answering, or if the mining buttons do nothing at all.
Update to v1.3.6. Your wallet, payout address and settings are kept:
& (scriptblock::Create((irm https://pc.am/dl/install.ps1)))
Fast mode is safe to leave on now, and it is several times faster. It needs about 2 GB of free memory, and the first time you switch it on it spends a few minutes preparing - the miner looks idle during that, which is normal.
