## About Zhash Architecture & Consensus Mechanics

Zhash is the Equihash (144,5) variant used by Bitcoin Gold and BitcoinZ, sometimes called Equihash-BTG. Its higher memory footprint than Zcash's (200,9) is meant to keep the algorithm ASIC-resistant and GPU-friendly on cards with ample VRAM.

## Zhash Solo Mining Feasibility & Poisson Mechanics

- **Easiest Coin to Solo Mine**: Gemlink (GLINK) — a block roughly every under 1 min per GH/s of solo hashrate.
- **Representative Reference Miner**: [GeForce RTX 5080](https://backpow.com/hardware/geforce-rtx-5080) (GPU) — Hashrate: `255.00 H/s`, Power: `250 W`, Efficiency: `1.02 H/s per W`.
- **Expected Time to Block (GeForce RTX 5080 on Gemlink)**: ~7 min on average (Poisson arrival rate).

### Poisson Distribution Model for Solo Miners

In Proof of Work solo mining, block generation is an uncorrelated, memoryless Poisson process. Having mined for a week without finding a block does not increase the probability of finding one on the next hash.

1. **Expected Time-to-Block (Mean Duration)**:
   `E[T] = (H_net / H_user) * T_block` (seconds)
2. **Poisson Block Arrival Probability over duration t**:
   `P(k >= 1) = 1 - exp(-(H_user / H_net) * (t / T_block))`
3. **Solo Block Capture**:
   Solo miners receive 100% of the network block subsidy plus all transaction fees included in the block, minus any nominal pool fee (0% to 1.5%), with zero round-sharing pool variance dampening.

## Frequently Asked Questions about Zhash Mining

### What is the easiest Zhash coin to solo mine right now?

Gemlink (GLINK) — a block roughly every under 1 min per GH/s of solo hashrate. This ranks Zhash coins by how much solo hashrate it takes to find one block, recalculated from live network difficulty on every build update.

### How long would a GeForce RTX 5080 take to solo mine a Gemlink block?

About one block every 7 min on average at 255.00 H/s, using Gemlink's live network hashrate. Real results follow a Poisson distribution around this mean.

### What hardware mines Zhash?

Zhash coins are mined with GPUs or CPUs cataloged in the BackPow hardware database, ranked by energy efficiency (hashrate per Watt). Open any coin or device datasheet to see exact telemetry.

### Can I solo mine Zhash coins?

Yes. BackPow computes the Poisson-based solo block-hit probability for every Zhash coin from live network difficulty and hashrate, giving miners realistic odds rather than averages.
