## About Etchash Architecture & Consensus Mechanics

Etchash (the 'Thanos' upgrade) is Ethereum Classic's modified Ethash, tuned so the DAG grows more slowly and stays within reach of smaller-memory GPUs. It is memory-hard and GPU-mined, closely related to Ethash but with its own epoch schedule.

## Etchash Solo Mining Feasibility & Poisson Mechanics

- **Easiest Coin to Solo Mine**: Etica (Etchash) (EGAZ) — a block roughly every 5 min per GH/s of solo hashrate.
- **Representative Reference Miner**: [NVIDIA CMP 170HX](https://backpow.com/hardware/nvidia-cmp-170hx) (GPU) — Hashrate: `163.72 MH/s`, Power: `205 W`, Efficiency: `798.64 KH/s per W`.
- **Expected Time to Block (NVIDIA CMP 170HX on Etica (Etchash))**: ~31 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 Etchash Mining

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

Etica (Etchash) (EGAZ) — a block roughly every 5 min per GH/s of solo hashrate. This ranks Etchash 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 NVIDIA CMP 170HX take to solo mine a Etica (Etchash) block?

About one block every 31 min on average at 163.72 MH/s, using Etica (Etchash)'s live network hashrate. Real results follow a Poisson distribution around this mean.

### What hardware mines Etchash?

Etchash coins are mined with ASICs or GPUs 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 Etchash coins?

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