PCoin (PCN) — CoinMarketCap listing request

We have submitted PCoin to CoinMarketCap. The ticket number is 1446171, filed from pcoin@pc.am.

This post exists so that CoinMarketCap can verify the request genuinely comes from the project rather than from someone impersonating it. That check is why they ask for a public post from an account linked on the project's own website.

Verify us independently:
• Website — https://pc.am
• Block explorer — https://explorer.pc.am
• Source code — https://github.com/pars5555/pcoin
• News & releases — https://pc.am/news/

For clarity: PCN is not traded on any exchange, so there is no price or volume. The request is for a Preview / Untracked listing only.

⛏ 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.

PCoin (PCN) — exchange listing progress

Two real steps forward this week:

1. ElectrumX servers are live for PCN (2 nodes, real SSL) — the hard prerequisite for non-custodial DEX listings.
2. The first PCN atomic swap settled end-to-end: 100 PCN for 17.5 DOGE, verified independently on both chains.

On the strength of that, we've filed for listing on Komodo DeFi Framework (formerly AtomicDEX) — a non-custodial DEX where nothing is held in a wallet you don't control. The PR is open and under review, not yet merged:
https://github.com/GLEECBTC/coins/pull/1964

Disclosure, because you should know before you trade: one address is currently finding ~62% of blocks over the last 300 (95% confidence interval 57-67%). Pool miners together account for about 34% of the same window. We track this publicly and will report it again as it changes.

The best way to change that number is more independent miners. PCoin mines on an ordinary CPU — no ASIC, no GPU needed. One command to start:
https://pc.am

PCoin (PCN) — the majority-risk address is gone, and the pool tripled

Two days ago we disclosed one address finding ~62% of blocks — real majority risk. Fresh numbers just now, same method (300-block window, 95% confidence interval), cross-checked against two independent nodes:

The largest solo miner is down to ~23% (18-27% CI). No single address is anywhere near a majority any more.

In the same 48 hours, the pool went from 13 miners to 41, and from ~92K H/s to ~585K H/s — a 6x jump. Network-wide hashrate is up 48% to ~657K H/s.

Honest disclosure, because the number moved rather than disappeared: the pool itself is now at ~65% of the network (60-70% CI) — the same "51% problem" concentration represents, just in a different place. Structurally lower risk than a single address (no pool wallet, no withdrawal — you're paid straight from each block's coinbase, so there's nothing to run off with) but still worth watching, and still checkable by anyone at pool.pc.am/api/pools against the network's own hashrate.

If you're joining now: the app (from v1.3.11) has a Mining Mode card that recommends solo or pool based on live chain data — so if you want to help keep this balanced rather than just adding to one side, it'll tell you which one actually helps right now.

Either way, it's one command:
Windows (PowerShell): & ([scriptblock]::Create((irm https://pc.am/dl/mine.ps1)))
Linux: curl -fsSL https://pc.am/dl/mine.sh | sudo sh

No GPU, no ASIC — an ordinary CPU competes. We'll keep reporting this as it changes.

Correction: the pool number in my last post was already stale when I posted it

A couple of hours ago I said the pool holds ~65% of the network. That was a 300-block trailing average, and it was blending two very different periods without saying so.

What actually happened: the address behind the original 62% disclosure has gone completely silent — zero blocks in its most recent 186, after finding most of an earlier stretch. My 300-block window covered both the old hot period and the new quiet one, so it averaged them into a number that was already out of date.

Measured on just the blocks since that address went quiet: the pool is running 84-90% right now, not 65%. That's the number that actually matters if you're deciding whether to trust anything today.

There's real good news buried in the same data, and I undersold it: that address isn't at 23% either, it's at 0%, fully stopped. Solo mining is now spread across 16+ distinct addresses with no single one above ~3-6%. The single-address risk is more resolved than I said.

Lesson for us, said plainly: on a chain this size, one address can add or remove a large share of hashrate in a single config change, and a multi-hour average can describe a state that no longer exists. We've pulled the specific percentage off pc.am for exactly this reason — check pool.pc.am/api/pools yourself for the current number rather than trust a snapshot from either of us, us included.

Same conclusion as before, now for the right reason: the responsible venues are still the non-custodial ones. We caught this ourselves within hours by cross-checking against the same hourly chain monitor we already run — publishing that check is exactly why it's worth running.

PCoin v1.3.13 released

v1.3.13 - Android: the miner's coin gets room to breathe

Download and checksums: https://pc.am/#download

🔁 wPCN can be redeemed back into PCN

The door opens both ways. Holding wPCN and want real PCN? Call redeem() on the contract with your PCoin address. It burns your wPCN, and we send the PCN.

Why this matters
A wrapped token nobody can redeem is an IOU on trust. A redeemable one is checkable — and it is what lets arbitrage hold the two prices together.

Verify the backing yourself
Reserve: pc1q7hhzmdkkx0zjtzj6qkwmuvhlgwfqjrc6j2dk52
50,000 PCN held against 50,000 wPCN issued. Both numbers are public — check them on explorer.pc.am rather than taking our word for it.

⚠️ Redemption is manual. A person sends the PCN, so allow hours.

🖥 PCoin now runs two ElectrumX servers

Wallet infrastructure, the kind every real chain needs:

electrum1.pc.am
electrum2.pc.am
SSL 50002 · WSS 50004 · TCP 50001

Separate providers, separate countries, each with its own full node and a real certificate, checked from outside every 10 minutes.

And a listing has been filed
PCN is submitted to the Komodo DeFi Framework — non-custodial atomic swaps, where no exchange ever holds your coins. The first swap is already done: 100 PCN traded for DOGE, settled on both chains.

⚠️ Submitted is not accepted. It is a request and it can be refused. Track it yourself: PR #1964
