## About Sia Architecture & Consensus Mechanics

Sia's proof-of-work uses Blake2b, a fast cryptographic hash that is not memory-hard, so throughput dominates. Efficient Blake2b ASICs (from vendors like Goldshell and Bitmain) long ago displaced GPUs on Siacoin and ScPrime.

## Sia Solo Mining Feasibility & Poisson Mechanics

- **Easiest Coin to Solo Mine**: ScPrime (SCP) — a block roughly every 36.6 years per GH/s of solo hashrate.
- **Representative Reference Miner**: [iBeLink BM-S3+](https://backpow.com/hardware/ibelink-bm-s3-1) (ASIC) — Hashrate: `25.00 TH/s`, Power: `3400 W`, Efficiency: `7.35 GH/s per W`.
- **Expected Time to Block (iBeLink BM-S3+ on ScPrime)**: ~12.8 hours 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.

## Sia Mining Hardware Benchmarks & Efficiency Rankings

## Sia Solo Mining Pools

No public solo mining pools are currently registered in the BackPow database for Sia. Miners can solo-mine directly by configuring hardware to point to a local full node daemon via RPC/Stratum bridge.

## Frequently Asked Questions about Sia Mining

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

ScPrime (SCP) — a block roughly every 36.6 years per GH/s of solo hashrate. This ranks Sia 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 iBeLink BM-S3+ take to solo mine a ScPrime block?

About one block every 12.8 hours on average at 25.00 TH/s, using ScPrime's live network hashrate. Real results follow a Poisson distribution around this mean.

### What hardware mines Sia?

Sia 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 Sia coins?

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