PCoinWindows and Linux update
A desktop release: the node, CLI and tray miner. The Android apps are unchanged and still come from their own releases — every download link here is pinned to the release that built it, so the parts move independently.
Android wallet update
A wallet-only release. The miner, Windows and Linux downloads are unchanged and still served from v1.2.6 — every download link on this site is pinned to the release tag that built it, so a single-component release like this one cannot break the others.
Release assets now name their role
Artifacts became pcoin-<platform>-<role>.<ext> —
for example pcoin-win64-miner.zip and pcoin-android-wallet.apk.
The previous names are still published as byte-identical aliases so that saved copies
of the install scripts keep working.
The Windows zip now also contains the tray miner. Earlier zips held only the node and the CLI, which produced an install that reported success and left a desktop shortcut pointing at a file that had never been installed.
LWMA difficulty activated at height 2800
Difficulty now retargets on every block using a 60-block linearly weighted moving average, replacing Bitcoin's 2016-block retarget. On a young chain with little hashrate, a two-week retarget window is far too slow — a single miner arriving or leaving distorts block times for days.
The change was height-gated, and so was the accompanying tightening of the future-block-time limit from two hours to fifteen minutes. Every node followed and there was no chain split.
Debian packaging fixed
The .deb had declared only libc6 as a dependency. The
binaries link libevent dynamically, so on distributions shipping only
libevent_core the node installed cleanly and then failed at every start.
All three libevent modules are now declared, with alternatives for the 64-bit
time_t rename.
Windows installer withdrawn
The Inno Setup installer was being quarantined by a Microsoft Defender machine-learning heuristic. It was a reputation false positive on the installer stub rather than anything in the code, and it aged out on its own, but the installer was dropped rather than shipped under a warning. Windows is distributed as a portable zip.
Note that all binaries are unsigned, so SmartScreen will warn on first run. That is a separate mechanism from Defender and only a code-signing certificate removes it.
Miner and wallet split into two Android apps
One source tree, two products: a miner and a wallet-only build with mining compiled out, for people who want to hold and send PCN without running a miner.
CPU miner concurrency fix
Two tray applications on one machine could issue startmining
simultaneously and terminate the process. The miner lifecycle is now serialised under a
single mutex.
Android, and the LWMA code ships
First Android build, and the release that carried the LWMA implementation ahead of its activation at height 2800 a week later. Shipping consensus code before the height it activates is what allowed the fork to land without a split.
First patch release
Windows and Android builds, one day after launch.
Mainnet launched
Block 0 was mined with the message
“PCoin 01/Aug/2026 an independent chain is born”, hash
a95d51f0cbf25cad…264a.
No premine, no founder allocation, no ICO, no token sale and no vesting. Every coin in existence was produced by RandomX proof-of-work from block 1 onward. Supply is published as machine-readable endpoints at /supply/supply.json.
What is being worked on
A mining pool. RandomX over a Bitcoin-style header means no existing pool software runs unmodified, so it is being written. The share validator agrees with the chain on 100 real blocks and assembled blocks are accepted by a node. It is open now at pool.pc.am, stratum on port 3333. Solo mining is supported today and is not going away.
No dates are promised for this or anything else.
