[ANN] ParnianCoin (PARC) - RandomHash2 CPU PoW | Pool | Web Wallet | Explorer

ParnianCoin (PARC)

What is it?

ParnianCoin is a cryptocurrency built as a fork of PascalCoin, rebranded and extended with its own infrastructure: a public node, a block explorer, a web-based wallet, and a mining pool. No desktop client is required — everything runs through the web wallet.

0How do I use it?

Create an account at the web wallet using email or Google/Microsoft OAuth — no key files to manage manually. Your account ID/public key appears on your dashboard, which you use to receive PARC. To mine, download the custom rhminer fork, point it at the pool with your account ID, and start submitting shares.

Why should I care?

- CPU-friendly RandomHash2 algorithm — no specialized hardware needed

- Network is newly launched with low difficulty — a good time for small and mid-size miners

- Fully transparent about being a PascalCoin fork; fee structure disclosed openly (20% dev fee + 0.5% pool fee)

- Multi-language site: English, Arabic, Persian

I don’t see the connection to Litecoin, is there any. Can we buy parniancoin with Litecoin?
You have a week to add it if or make it more visible.

Hi Nickz, thanks for the heads-up and the fair deadline. You’re right that the Litecoin link wasn’t clear. We’re adding a direct “Buy PARC with LTC” option on parniancoin dot com, with LTC as the primary payment method. I’ll update the first post with details and a link within the week. If you’d prefer we move the thread elsewhere in the meantime, just let me know.

Great once you are ready feel free to open an offer in Market Place. Give as much detail and make sure you mention to accept litecoin wherever you post.

Thanks Nickz, done. You can now buy PARC with Litecoin directly in our web wallet:
wallet.parniancoin dot com/market

How it works:

  • Pick an amount, the wallet shows the exact LTC to send plus a QR code.
  • LTC goes straight to the seller’s Litecoin address.
  • The PARC is held in escrow and released to the buyer automatically after 6 LTC confirmations (about 15 minutes).
  • Holders can also list their own PARC for LTC on the same page.

Current price: 0.0072 LTC per PARC (about $0.50), minimum order 1 PARC.
I’ll open an offer in the Marketplace with full details, as you suggested.

Update: Parnian Pay — accept PARC on any website

We’ve launched Parnian Pay, a non-custodial payment gateway for ParnianCoin. You can find it on the “pay” subdomain of our official website (listed in the first post of this thread).

• Payments go straight from the buyer’s wallet to the merchant’s own PARC account — the gateway never holds funds or keys
• Buyers sign in their own wallet; no shop (and not us) ever sees a private key
• Simple REST API with signed webhooks (full API docs on the gateway site)
• Ready-made plugins for WooCommerce, OpenCart and PrestaShop
• Available in English, Persian and Arabic

Merchants can create an account directly on the gateway site.

Feedback from developers and shop owners is very welcome — bug reports, feature requests, or plugins for other platforms you’d like to see.

Also: PARC is now listed on Blockspot dot io — search for “ParnianCoin” there to see our profile.

One thing worth spelling out next to the escrow terms: since the buyer’s LTC goes straight to the seller’s address, the escrow only covers the PARC side. If an order falls through after payment, getting the LTC back depends on the individual seller, and buyers should know that before they send. We’d also look closely at how payments are matched to orders. When several orders point to the same seller address, telling them apart by amount alone gets fragile, especially when a buyer pays from an exchange that takes its withdrawal fee out of the amount sent. A fresh address per order, derived from the seller’s xpub, is the usual way LTC payment processors avoid that, with the trade-off that sellers share their address history with the platform.

Thanks, this is exactly the kind of review we need, and you’re right on both points.

  1. Escrow scope
    Correct: the escrow only protects the PARC side. Once the buyer sends LTC directly to the seller, getting it back depends on the seller. We’ll make this explicit on the market page and in the order screen before the buyer pays, so nobody sends LTC without knowing it.

  2. Payment matching
    Also correct. Matching by amount works at our current volume, but it breaks down exactly in the case you describe (exchange withdrawals that deduct fees, or several open orders to the same seller). We’re looking at per-order addresses derived from the seller’s xpub, with the privacy trade-off clearly explained to sellers so they can choose. As an interim step we’ll stop allowing two open orders with the same amount to the same seller address, and flag underpaid orders for manual review instead of auto-matching them.

We’ll post an update in this thread once these changes are live.

If ChangeNOW ever looks at small CPU-mined coins, we’d be glad to provide a public node, RPC access and anything else needed for an integration review.

Update: how PARC pricing works now

When we opened the PARC/LTC market, we listed an initial price of 0.0072 LTC per PARC. That was only a starting reference. From now on, the team does not set the price.

- Sellers list PARC at their own price in LTC on the market page of the web wallet (wallet subdomain of parniancoin dot com, under /market)

- The market price shown in the wallet, pools and Parnian Pay is calculated from completed trades, using a weekly volume-weighted average (VWAP)

- Until the first trades complete, you will only see sellers’ asking prices, not a market price

There are open sell offers right now and no completed trades yet, so the first buyers will effectively set the first real reference price.

Other updates:

- Our CPU miner is now available as a HiveOS / mmpOS custom miner (see the releases page of our miner repository on GitHub, linked from the official site)

- A second independent pool and stratum are live for failover

Full details and all links are on the official site: parniancoin dot com

Following the review from Change_NOW above:

- The market page and order screen now state clearly that escrow only covers the PARC side, before the buyer sends LTC

- Two open orders with the same amount to the same seller address are no longer allowed, and underpaid orders are flagged for manual review

Update: parnianminer 2.4.2 is out.

It fixes a bug in the Windows build that caused many “low difficulty share” rejects (30-60%). One of the hash steps inside RandomHash2 (BLAKE2s) gave wrong results on Windows only. Linux and HiveOS were fine.

Same PC test: 2.4.1 about 50% rejected, 2.4.2 0% rejected.

Windows miners: please update. Downloads are on the ParnianCoin GitHub releases page (search “parniancoin-miner” on GitHub) or via parniancoin dot com. Your command line stays the same.
