## About X11 Architecture & Consensus Mechanics

X11 is Dash's proof-of-work, chaining eleven different hash functions (Blake, BMW, Groestl, JH, Keccak, Skein, Luffa, Cubehash, SHAvite, SIMD and Echo). It was designed to run cool and efficiently on GPUs, but is now firmly ASIC-dominated and is not memory-hard.

## X11 Solo Mining Feasibility & Poisson Mechanics

- **Easiest Coin to Solo Mine**: Kerrigan-X11 (KRG) — a block roughly every 32.7 days per GH/s of solo hashrate.
- **Representative Reference Miner**: [Bitmain Antminer D9](https://backpow.com/hardware/bitmain-antminer-d9) (ASIC) — Hashrate: `1.77 TH/s`, Power: `2839 W`, Efficiency: `623.90 MH/s per W`.
- **Expected Time to Block (Bitmain Antminer D9 on Kerrigan-X11)**: ~27 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 X11 Mining

### What is the easiest X11 coin to solo mine right now?

Kerrigan-X11 (KRG) — a block roughly every 32.7 days per GH/s of solo hashrate. This ranks X11 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 Bitmain Antminer D9 take to solo mine a Kerrigan-X11 block?

About one block every 27 min on average at 1.77 TH/s, using Kerrigan-X11's live network hashrate. Real results follow a Poisson distribution around this mean.

### What hardware mines X11?

X11 coins are mined with ASICs 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 X11 coins?

Yes. BackPow computes the Poisson-based solo block-hit probability for every X11 coin from live network difficulty and hashrate, giving miners realistic odds rather than averages.
