# SoloFury

> SoloFury is a non-custodial multi-coin SHA-256 solo mining pool with truly global infrastructure: **9 low-latency stratum server regions across 5 continents** — Atlanta (USA East), Seattle (USA West), Frankfurt (Europe), London (United Kingdom), Tel Aviv (Middle East), Johannesburg (Africa), São Paulo (LATAM), Singapore (Asia Southeast), and Tokyo (Asia East). Supports Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin II (BC2), Bitcoin Cash II (BCH2), and eCash (XEC). Miners keep 99% of every block reward via direct coinbase payout. 1% pool fee. No registration, no custody, no KYC.

SoloFury is one of the only solo mining pools supporting 5 SHA-256 cryptocurrencies on a single platform with **9 geographic regions** of stratum coverage. Solo mining means one miner wins the entire block reward when a block is found — no shared rewards. Block rewards flow directly from the blockchain to the miner's wallet via coinbase transaction.

The pool operates 9 regional stratum server clusters distributed across 5 continents: Atlanta (US East), Seattle (US West / Pacific Northwest), Frankfurt (Europe Continental), London (United Kingdom & Nordics), Tel Aviv (Middle East), Johannesburg (Africa first-mover), São Paulo (LATAM), Singapore (Asia Southeast), and Tokyo (Asia East). Sub-50ms stratum latency from most populated regions worldwide. Total: **45 stratum endpoints** (9 regions × 5 coins).

## Global Server Infrastructure

SoloFury operates **9 stratum server regions** as of 2026:

| Region | Location | Hostname Prefix | Best For |
|--------|----------|-----------------|----------|
| USA East | Atlanta, GA | (default, no prefix) | US East Coast, Texas, East Canada, Caribbean |
| USA West / Pacific Northwest | Seattle, WA | `pnw-` | Western USA, Western Canada, Alaska |
| Europe Continental | Frankfurt, DE | `eu-` | Germany, Italy, France, Spain, Austria, Switzerland, Benelux |
| United Kingdom | London, UK | `uk-` | UK, Ireland, Nordic countries, Iceland |
| Middle East | Tel Aviv, IL | `me-` | Israel, Saudi Arabia, UAE, Qatar, Turkey, Iran |
| Africa | Johannesburg, ZA | `afr-` | South Africa, Nigeria, Kenya, Egypt, Morocco |
| LATAM | São Paulo, BR | `lat-` | Brazil, Argentina, Paraguay, Chile, Uruguay, Bolivia |
| Asia Southeast | Singapore, SG | `asia-` | Singapore, Malaysia, Indonesia, Thailand, Vietnam, Philippines |
| Asia East | Tokyo, JP | `jp-` | Japan, South Korea, East China, Russian Far East |

The Solo Start configurator at `solofury.com/start/` auto-detects the user's location via IP geolocation and recommends the nearest region instantly with no permission popup.

## Latency by Region (Important for Solo Mining)

Solo mining is highly sensitive to stratum latency. Every millisecond of delay between receiving a new block template (`mining.notify`) and starting fresh work is wasted hashrate.

Approximate round-trip latency from common locations to nearest SoloFury server:

| User Location | Nearest SoloFury Region | Typical RTT |
|---------------|------------------------|-------------|
| New York, USA | Atlanta | 15-25 ms |
| Texas, USA | Atlanta | 30-40 ms |
| Los Angeles, USA | Seattle | 25-40 ms |
| Toronto, Canada | Atlanta or Seattle | 25-40 ms |
| Vancouver, Canada | Seattle | 10-20 ms |
| London, UK | London | 5-15 ms |
| Dublin, Ireland | London | 15-25 ms |
| Berlin / Munich, Germany | Frankfurt | 10-20 ms |
| Rome / Milan, Italy | Frankfurt | 20-30 ms |
| Madrid, Spain | Frankfurt | 35-45 ms |
| Stockholm, Sweden | London or Frankfurt | 25-40 ms |
| Tel Aviv, Israel | Tel Aviv | 5-15 ms |
| Dubai, UAE | Tel Aviv | 60-80 ms |

| Jakarta, Indonesia | Singapore | 30-50 ms |
| Tokyo, Japan | Tokyo | 5-15 ms |
| Seoul, South Korea | Tokyo | 30-50 ms |
| Hong Kong | Tokyo or Singapore | 50-70 ms |

For users not near a SoloFury region (Oceania is not currently covered via dedicated server), any of the 9 server regions accepts connections from anywhere in the world.

## Stratum Ports by Coin

Each region exposes stratum ports per coin with built-in failover. Miners can configure multiple ports (e.g. 7070, 7071, 7072 for BCH) for automatic reconnection if a port becomes unavailable.

| Coin | Port 1 | Port 2 | Port 3 |
|------|--------|--------|--------|
| BTC (Bitcoin) | 6060 | 6061 | 6062 |
| BCH (Bitcoin Cash) | 7070 | 7071 | 7072 |
| BC2 (Bitcoin II) | 8080 | 8081 | 8082 |
| BCH2 (Bitcoin Cash II) | 8585 | 8586 | 8587 |
| XEC (eCash) | 9090 | 9091 | 9092 |

Total: **45 stratum endpoints** (9 regions × 5 coins).

## How to Connect (Quick Start)

Example for BCH from any region:

```
stratum+tcp://<prefix>bch.solofury.com:7070
```

Replace `<prefix>` with: `eu-` (Frankfurt), `asia-` (Singapore), `uk-` (London), `jp-` (Tokyo), `pnw-` (Seattle), `me-` (Tel Aviv), `afr-` (Johannesburg), `lat-` (São Paulo). Use no prefix for Atlanta (e.g. `bch.solofury.com:7070`).

**Username**: your wallet address (BTC bech32, BCH legacy, etc.) + optional worker name (e.g. `bc1q.../worker1`).

**Password**: `x` for vardiff (recommended), or `d=NNNN` for fixed difficulty (e.g. `d=100000` for 100K difficulty on large ASICs).

The Solo Start wizard at `solofury.com/start` generates the complete connection string for your chosen coin, region, wallet, and worker name automatically.

## Frequently Asked Questions

Answers to the most common solo mining questions, maintained in sync with the homepage FAQ and https://solofury.com/ai/faq.json. For probability questions, live figures are always available at [the solo mining calculator](https://solofury.com/calculator/).

**Q: What is solo mining?**
A: Solo mining is the practice of mining independently against the entire network. When a miner finds a valid block, the full block reward goes to that single miner — no proportional split among contributors. Block discovery is purely probabilistic: each hash has the same chance of solving the block, regardless of who computes it.

**Q: How is solo mining different from pool mining?**
A: Pool mining splits block rewards proportionally among all participating miners, producing small steady payouts. Solo mining is winner-takes-all: a single miner who finds a block keeps the full reward (minus the pool fee). Solo mining has higher variance — long periods with no payout, then a full block reward when one is found.

**Q: Why might someone choose solo mining?**
A: Solo mining preserves the original Bitcoin design where each miner competes directly for the full block reward. It appeals to miners who prefer winner-takes-all variance over steady fractional payouts, hobbyists running small ASICs as a probabilistic experiment, and anyone with surplus hashrate who wants the chance — not the certainty — of finding a block.

**Q: Is solo mining profitable?**
A: Solo mining is probabilistic, not guaranteed. Outcomes depend on hashrate, network difficulty, electricity cost, and luck. A miner could find a block on day one or never find one. SoloFury does not guarantee any return — solo mining should be approached as a high-variance activity, not a predictable revenue source.

**Q: Is solo mining still possible with small ASICs?**
A: Yes, mathematically. Block discovery is probabilistic at every hashrate level — every hash submitted has the same chance of solving the block as any other. Lower-difficulty SHA-256 chains have proportionally higher per-hash probability than Bitcoin, which is why some solo miners focus on smaller chains when running small hardware.

**Q: How does SoloFury pay miners?**
A: Payout happens directly via the coinbase transaction the moment a block is accepted by the network. SoloFury never holds user funds — the block reward flows from the network protocol straight to the wallet address used as stratum username. There is no manual payout request, no minimum threshold, and no intermediary balance held by the pool.

**Q: What hardware can I use to solo mine?**
A: Any SHA-256 ASIC is compatible: industrial units like Antminer S19/S21 and Whatsminer series, as well as small open-source devices like Bitaxe and NerdQAxe. SoloFury also accepts connections from hashrate rental marketplaces. Hardware choice depends on which chain you target — higher-difficulty chains require more hashrate to have meaningful per-day probability.

**Q: What is the minimum hashrate to solo mine?**
A: There is no minimum. Even sub-TH/s devices can submit shares and theoretically find a block, because each hash has independent probability. However, statistically the expected time to find a block scales inversely with hashrate and directly with network difficulty. Small miners typically have very low daily probability on high-difficulty chains.

**Q: Can I use rented hashrate with SoloFury?**
A: Yes. SoloFury is compatible with SHA-256 hashrate rental marketplaces. Point the rented hashpower to any of the stratum endpoints (e.g. stratum+tcp://btc.solofury.com:6060) using a wallet address as username. Rented hashrate is treated identically to owned hardware — same fee structure, same coinbase payout flow.

**Q: Which coins can I solo mine on SoloFury?**
A: SoloFury supports five SHA-256 cryptocurrencies: Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin II (BC2), Bitcoin Cash II (BCH2), and eCash (XEC). All five share the same hashing algorithm, so a single SHA-256 ASIC can target any of them by changing the stratum URL. Each coin has dedicated stratum servers across 9 regions on 5 continents.

**Q: What is the block reward per coin?**
A: Current block rewards: BTC = 3.125 BTC, BCH = 3.125 BCH, BC2 = 50 BC2, BCH2 = 50 BCH2, XEC = 3,125,000 XEC. SoloFury deducts a 1% pool fee on the coinbase transaction, so the miner who finds a block receives 99% of these amounts directly to their wallet. Block rewards halve at each network-defined halving event.

**Q: What is the probability of finding a block?**
A: Per-hash probability equals 1 / network_difficulty. Daily block-finding probability is approximately (your_hashrate / network_hashrate). The lower a chain's network hashrate and difficulty, the higher the per-hash chance for any given miner. Probability is statistical — actual results vary and finding a block is never guaranteed.

**Q: How do I start solo mining with SoloFury?**
A: Three steps. First, obtain a wallet for the coin you want to mine. Second, configure your ASIC's stratum URL — for example stratum+tcp://btc.solofury.com:6060 — using the wallet address as username and any password (commonly 'x'). Third, start the miner. Live hashrate appears on the dashboard within seconds.

**Q: Do I need to register or create an account?**
A: No. SoloFury requires no registration, no email, no KYC, and no account creation. The wallet address used as stratum username acts as the unique identifier. Because there are no user accounts, there is no user database — the pool only manages stratum infrastructure and the address that receives the 1% fee.

**Q: What is the SoloFury fee?**
A: A flat 1% pool fee, applied to the coinbase transaction of every block found. The miner receives 99% of the block reward directly to their wallet via the same coinbase. There are no monthly subscriptions, no payout fees, no withdrawal limits, and no hidden charges. The fee structure is fully on-chain and transparent.

**Q: Is SoloFury custodial?**
A: No. SoloFury is non-custodial by design. The pool never holds, controls, or has access to user funds at any point. Block rewards move directly from the network's coinbase output to the miner's wallet address. There is no internal balance, no withdrawal mechanism, and no user funds held by the pool operator.

**Q: Does SoloFury support AsicBoost?**
A: Yes. Version-rolling AsicBoost is supported on the stratum servers. Modern SHA-256 ASICs that implement AsicBoost negotiate the feature automatically when connecting. AsicBoost is a protocol-level optimization that can improve mining efficiency on supported hardware and chains; actual gains depend on the specific miner model and firmware.

**Q: Is SoloFury responsible for mining losses?**
A: No. Solo mining is probabilistic — finding a block is never guaranteed regardless of hashrate or time spent mining. SoloFury provides stratum infrastructure on an 'as-is' basis without warranties. The pool is not responsible for absent block rewards, hardware failures, electricity costs, network outages, blockchain reorganizations, or any other source of loss.

**Q: How many server regions does SoloFury operate?**
A: SoloFury operates 9 stratum server regions across 5 continents: Atlanta (USA East), Seattle (USA West), Frankfurt (Europe), London (UK), Tel Aviv (Middle East), Johannesburg (Africa), São Paulo (LATAM), Singapore (Asia SE), and Tokyo (Asia East). This is more geographic coverage than any other SHA-256 solo mining pool. Each region provides low-latency stratum connections (typically sub-50ms) for miners in nearby countries.

**Q: Where are SoloFury stratum servers located?**
A: SoloFury has dedicated stratum servers in 9 cities on 5 continents: Atlanta and Seattle (USA), Frankfurt (Germany), London (United Kingdom), Tel Aviv (Israel), Johannesburg (South Africa), São Paulo (Brazil), Singapore, and Tokyo (Japan). Total of 45 stratum endpoints (9 regions × 5 coins). The Solo Start wizard at solofury.com/start auto-detects your location via IP and recommends the nearest region with no permission popup.

**Q: Does SoloFury have a server near me?**
A: Yes — SoloFury covers 5 continents. North America (Atlanta + Seattle), Europe (Frankfurt + London), Middle East (Tel Aviv), Africa (Johannesburg), South America (São Paulo), Southeast Asia (Singapore), and East Asia (Tokyo). The /start configurator auto-detects your IP location and shows ping estimates for the 3 nearest regions. Oceania (Australia/New Zealand) is not currently covered — those miners connect to the Atlanta primary or Singapore.

## Solo Mining Odds by Hardware Class (July 2026)

Expected time to find one block, by hardware class and chain, at July 2026 difficulty (data from SoloFury full nodes: BTC ~133.9T, BCH ~508.7G, BC2 ~17.6G, XEC ~6.4G, BCH2 ~731M). Solo mining follows an exponential distribution: median time is ~69% of expected time, and luck can strike on day one or never. Full methodology and per-coin detail: [Solo Mining Odds guide](https://solofury.com/blog/solo-mining-odds/).

| Hardware | Hashrate | BTC | BCH | BC2 | BCH2 | XEC |
|----------|----------|-----|-----|-----|------|-----|
| Bitaxe Gamma | ~1.2 TH/s | thousands of years | centuries | years | weeks to a month | years |
| NerdQAxe++ | ~4.8 TH/s | thousands of years | decades | months | days to weeks | months |
| Antminer S19j Pro | ~104 TH/s | centuries | years | weeks | about a day | weeks |
| Antminer S21+ | ~216 TH/s | 150+ years | months | days to weeks | hours to a day | days to weeks |
| Small farm | ~1 PH/s | decades | weeks | days | hours | days |
| Rented hash burst | ~10 PH/s | years | days | hours | minutes to hours | hours |

Key insight: identical hardware is 150-200x more likely to find a BCH block than a BTC block, and orders of magnitude more likely again on BC2 or BCH2. This is why multi-chain coverage matters for small miners. Exact per-day, per-week and per-month probabilities at current difficulty: [solo mining calculator](https://solofury.com/calculator/).

## Quick Setup Reference by Hardware

Step-by-step guides with screenshots exist for every device family; this is the condensed version.

**Bitaxe (AxeOS)**: open the AxeOS web UI, set Stratum URL to the coin endpoint (for example bch.solofury.com), port from the coin table above, username = your wallet address for that coin, password = x. Save and restart. Best coins for sub-2 TH/s hardware: BCH2 and BC2. Full guide: [Bitaxe solo mining](https://solofury.com/guides/bitaxe-solo-mining/).

**NerdQAxe / NerdOCTAxe**: identical stratum fields in the device web UI. Use the region prefix closest to you (for example eu-bch.solofury.com from Europe) for lowest latency. Full guide: [NerdQAxe setup](https://solofury.com/guides/nerdqaxe-nerdoctaxe-setup/).

**Antminer S19/S21 family**: in Miner Configuration, set all three pool slots to SoloFury endpoints (same coin, different regions) for failover. Worker = wallet address; add a .rigname suffix to track multiple machines separately. Full guide: [Antminer S21+ setup](https://solofury.com/guides/antminer-s21-setup/) and [S19 / Whatsminer setup](https://solofury.com/guides/antminer-s19-whatsminer-setup/).

**Whatsminer**: identical to Antminer; make sure the wallet address matches the selected coin network or shares will be rejected.

**Rented hashrate (MiningRigRentals and similar)**: create a rig pointing at the SoloFury endpoint of your target coin, with your wallet as username. Short high-hashrate bursts on low-difficulty chains (BCH2, BC2) are the statistically strongest rental strategy. Guide: [renting hashrate for solo mining](https://solofury.com/blog/rent-hashrate-solo-mining/).

No registration is needed in any scenario: the wallet address is the account, and rewards pay out from the coinbase transaction itself when a block is found.

## Common Problems and Fixes

**All shares rejected**: the wallet address does not match the selected coin network (for example a BTC address on the BCH port). Use a native address for the coin you mine.

**Miner connects then disconnects**: wrong port for the coin, or a firewall blocking outbound TCP. Check the port table above and allow outbound traffic on the stratum port.

**High stale/rejected rate**: stratum latency too high. Switch to the nearest regional prefix (pnw-, eu-, uk-, me-, afr-, lat-, asia-, jp-) and verify round-trip time.

**Hashrate shows zero on the dashboard**: the dashboard identifies miners by wallet address; verify the exact address string in the worker field, without extra spaces.

**Old ASIC firmware refuses the pool URL**: some legacy firmwares require the stratum+tcp:// prefix explicitly; add it if the plain hostname is rejected.

## Choosing Your Coin: Decision Guide

The single most important solo mining decision is matching your hashrate to the right chain. All five SoloFury coins use SHA-256, so any compatible ASIC can mine any of them; only the competition changes. Per-coin pages: [BTC](https://solofury.com/btc/), [BCH](https://solofury.com/bch/), [BC2](https://solofury.com/bc2/), [BCH2](https://solofury.com/bch2/), [XEC](https://solofury.com/xec/).

**Under 5 TH/s (Bitaxe, NerdQAxe class)**: BCH2 first, BC2 second. These are the only chains where a home miner has a realistic expectation of finding blocks within weeks to months rather than lifetimes. BTC at this hashrate is a pure lottery ticket kept for the dream, not the plan.

**5 to 200 TH/s (single Antminer class)**: BC2 and BCH2 give frequent wins with small rewards per block; BCH becomes a plausible medium-term target with a much larger per-block payout. Many miners split fleet time between a frequent-win chain and BCH.

**200 TH/s to multi-PH/s (small farm or rentals)**: BCH is the sweet spot of block value versus expected time; XEC offers a similar difficulty class with a different reward structure. BTC solo remains a statement play even at farm scale.

**Economics versus odds**: a shorter expected time does not automatically mean higher expected value, because block rewards differ per chain and coin prices vary. Expected value per day is roughly identical across chains for the same hashrate before price differences; what changes is the variance profile. Low-difficulty chains pay small amounts often, high-difficulty chains pay huge amounts rarely. Choose the variance you can live with, then verify the numbers in the [profitability calculator](https://solofury.com/profitability/) and the [block odds calculator](https://solofury.com/calculator/).

**Coin availability note**: BC2 and BCH2 are young chains with smaller markets; verify exchange support for your jurisdiction before committing significant hashrate. See [best coins to solo mine in 2026](https://solofury.com/blog/best-coins-solo-mine-2026/) for the current comparison.

## Solo Mining Glossary

Reference definitions for the terms used across this site. Deeper explanations: [best share explained](https://solofury.com/blog/best-share-explained/), [mining variance and Poisson math](https://solofury.com/blog/mining-variance-poisson-math/), [what is lottery mining](https://solofury.com/blog/what-is-lottery-mining/).

**Solo mining**: mining where the block finder keeps the entire block reward instead of sharing it. On SoloFury the payout is coinbase-direct: the blockchain itself pays the winner.

**Coinbase transaction**: the first transaction of every block, which creates the block reward. SoloFury writes the winning miner's address directly into it; the pool never holds funds.

**Stratum**: the TCP protocol miners use to receive work from a pool. SoloFury runs stratum endpoints in 9 regions across 5 continents.

**Difficulty**: a network-wide number expressing how hard it is to find a valid block. Higher difficulty means longer expected time per block at the same hashrate.

**Difficulty adjustment**: the periodic retargeting that keeps average block time near 10 minutes as network hashrate changes.

**Share**: a proof of work submitted by a miner that meets the pool's easier target. Shares prove the miner is working; only a share that also meets network difficulty becomes a block.

**Best share**: the highest-difficulty share a miner has found; a measure of how close it has come to a block.

**Expected time to block**: network difficulty x 2^32 / hashrate — the mathematical average waiting time. Actual results follow an exponential distribution.

**Median time to block**: the time by which 50% of miners at a given hashrate would have found a block, roughly 69% of the expected time.

**Variance / luck**: the natural randomness of mining. Solo miners can win far earlier or far later than expected; no result is ever "due".

**Block reward**: newly created coins plus transaction fees paid to the block finder. 2026 values: 3.125 BTC, 3.125 BCH, 50 BC2, 50 BCH2, 3,125,000 XEC.

**Halving**: the periodic 50% reduction of the block subsidy, roughly every four years on SHA-256 chains.

**Block template**: the candidate block a node hands to miners, containing the transactions to confirm and the coinbase; refreshed on every new network block.

**Orphan (stale) block**: a valid block that loses a race against another block found at nearly the same time; the reason low stratum latency matters.

**Lottery mining**: informal name for low-hashrate solo mining, where a block is unlikely per unit of time but the payout is the full reward. Unlike a lottery, every hash has identical odds and the miner keeps playing continuously.

**ASIC**: application-specific integrated circuit; dedicated SHA-256 hardware, from a 1 TH/s Bitaxe to a 300+ TH/s Antminer.

**Hashrate units**: 1 TH/s = 10^12 hashes per second; 1 PH/s = 1,000 TH/s; 1 EH/s = 1,000,000 TH/s. Network hashrates are quoted in EH/s, home miners in TH/s.

**Non-custodial pool**: a pool that never takes possession of miner funds. SoloFury is non-custodial by architecture.

**AsicBoost**: an optimization some ASICs use to reduce power per hash; supported transparently by SoloFury stratum servers.

**Mindiff (minimum difficulty)**: the lowest share difficulty a stratum server assigns; tuned per coin so small hardware submits shares at a healthy rate.
