About the coin (primary summary)

Summary on request

What the coin is: ParnianCoin (PARC) – a cryptocurrency based on PascalCoin, with its own web‑wallet, block explorer, and mining pool. The project is positioned as a more accessible version of PascalCoin that does not require installing a desktop client.

Mining algorithm: RandomHash2 (CPU‑friendly) – an algorithm specially designed for efficient operation on CPUs.

CPU‑only or not: Yes, the project is fully focused on CPU mining. The description explicitly states that PARC is “CPU‑friendly” and a regular PC or laptop can participate in mining.

Brief description: ParnianCoin – a fork of PascalCoin 5.4 with an expanded infrastructure: public node, block explorer, web‑wallet and mining pool. The main goal is to make the PascalCoin architecture more accessible to international users without the requirement of installing a desktop client.

Where to mine / pool: Mining is possible through the official pool https://pool.parniancoin.com or individually using the Parnian miner (rhminer fork) at https://parniancoin.ir/MinerFile/parnianminer-win64.zip

Wallet / links:

Community reaction: Early replies show that participants encountered connection problems to the pool (authorization errors), which were resolved after proper configuration via wallet.parniancoin.com. Announcements about the network launch and the search for new miners actively attract attention, and the team supports the project through Discord (https://discord.gg/m4AcMMReSs

Update history (deltas)

2026-09-25 00:15 UTC — 5 new posts

  • Main topic of new posts: Pool and miner updates for ParnianCoin, including fixing configuration bugs, port reorganization, and release of a new version of the Parnian miner with auto‑port, as well as clarification of a typical connection issue.
  • Key news / updates:
  • Fixed pool bug: with invalid characters in the public key the server no longer crashes; it now returns a clear message; the standard -pw flag is processed correctly and the Base58 key is displayed in the web‑wallet.
  • Pool ports changed: old 3334‑3338 closed, new ranges 38008‑38058 opened with variable difficulty (varDiff) for different hash‑rates (from ~100 kH/s up to >5 MH/s).
  • Released parnianminer v2.4: Smart Auto‑Port (port selection based on real hashrate), zero‑installation, improved API security, no developer fee.
  • Algorithm confirmed: RandomHash2 (same as PascalCoin v5+).
  • Problems / complaints:
  • Some miners could not save pool settings (public key, minimum payout, notifications) because the server crashed on invalid characters in the key and the password check was too strict for multithreaded connections.
  • A user received “Connection refused” and “not authorized” errors when trying to connect to port 38009 of the node instead of the stratum server; after specifying the correct stratum address and using the new miner version the issue was resolved.
  • Overall tone: Positive/neutral – the team promptly fixes bugs, improves infrastructure and provides clear instructions, which the community perceives as support and development of the project.

  • For solo mining, operate only against your own full node (http://127.0.0.1:<MINER_PORT>); everyone else is advised to use the official pool

Problems / complaints:

  • User HashCaliber reported an authorization error when connecting to the stratum server (node.parniancoin.com:38009: “px32a23c3eed9b03a2.rig1 is not authorized to connect”) and a connection refusal.

Main topic of new posts: Release of parnian‑miner 2.4.1 for HiveOS and mmpOS and fixing the high orphan‑block rate in the ParnianCoin network.

Key news / updates:

  • Release parnianminer 2.4.1: portable Linux build (glibc 2.17+), automatic pool‑port selection, primary and backup pools with automatic failover/failback, integration with HiveOS/mmpOS dashboards, secure local API, 0 % developer fee.
  • Instructions for adding the miner to HiveOS (Flight Sheet → Custom) and mmpOS (Custom URL pointing to the release).
  • Fixed an integer overflow bug in the solution‑submission path to the pool, which caused a high orphan rate (40‑60 %).
  • After the fix (08 Oct 2026, ~07:00 UTC): 130 blocks found by the pool, 128 confirmed, 2 awaiting maturity, 0 orphans; stable block flow, network height >10 824, hashrate ≈300 kH/s.
  • Miners should not change settings; payouts continue every 10 minutes for blocks with 100+ confirmations.
  • Re‑mention of HiveOS support via Custom miner and link to the guide.

Problems / complaints: Earlier reports of a high percentage of orphan blocks in the pool (up to 40‑60 %), leading to loss of miner rewards; the issue has been resolved with a server‑side fix.

Overall tone: Positive – emphasis on a successful miner update and restoration of stable network operation.

Main topic of new posts:

Network updates for ParnianCoin (orphan‑block fix, difficulty restoration), verification on Blockspot.io and release of a patched Windows miner, as well as community questions about the pool and marketplace.

Key news / updates:

  • Orphan‑block issue fixed: cause was an integer overflow in the node’s JSON parser (nonces > 2³¹ were rejected); the fix is already in place, and in the last ~280 blocks only one orphan block appeared.
  • Network difficulty is recovering after a hash‑rate spike and sharp miner exit on 9 Oct; difficulty is now roughly half of the peak and continues to decrease each block.
  • ParnianCoin received a ✅ Verified status on Blockspot.io; a short video was published and a call to vote “Bullish” to increase visibility.
  • Released parnian‑miner v2.4.2: bug in the BLAKE2s code of the Windows build that caused 30‑60 % share rejections (“low difficulty share”) has been eliminated; after the update, rejections are zero. Linux/HiveOS/mmpOS builds are unaffected.
  • Pool side: task switching reduced, “job not found” rejections now zero.
  • Mentioned active services: official pool (pool.parniancoin.com), web‑wallet (wallet.parniancoin.com), block explorer (explorer.parniancoin.com), merchant gateway Parnian Pay (pay.parniancoin.com).

Problems / complaints:

  • Windows miners experienced a high percentage of rejected shares due to the BLAKE2s bug (fixed in v2.4.2).
  • Temporarily increased block time after the sharp hash‑rate jump on 9 Oct (difficulty still being adjusted).
  • User Pinopnh asked how the pool and the LTC market were organized, expressing difficulty with their own project (not a complaint, but a request for information).

Overall tone:

Positive/neutral – focus on resolved issues, new achievements (verification, miner fix) and a call for community support, alongside constructive questions from participants.
