Multi-coin SHA-256 solo mining pool · BTC/BCH/BC2/BCH2/XEC · 9 global regions · Stratum V2 on BTC · 1% fee · 99% direct-to-wallet · No KYC

Official public documentation for SoloFury — a non-custodial multi-coin solo mining pool with truly global stratum infrastructure across 9 regions on 5 continents.

SoloFury is a multi-coin SHA-256 solo mining pool that supports five cryptocurrencies on a single platform:

• Bitcoin (BTC)
• Bitcoin Cash (BCH)
• Bitcoin II (BC2)
• Bitcoin Cash II (BCH2)
• eCash (XEC)

Solo mining means one miner wins the entire block reward when a block is found — no shared rewards, no pool payout schemes. Block rewards flow directly from the blockchain to the miner's wallet via the coinbase transaction.

• ✅ 1% pool fee (verifiable on-chain in every block's coinbase)
• ✅ 99% direct-to-wallet payout via coinbase transaction
• ✅ No registration, no custody, no KYC — your wallet address is your account
• ✅ 9 global stratum regions — sub-50ms latency from most populated regions worldwide
• ✅ Stratum V2 in production on BTC — encrypted end-to-end, coinbase verifiable from your own miner
• ✅ In development since 2024, publicly launched January 2026 — production-tested, transparent operator

Most solo mining pools support a single coin (typically BTC). SoloFury is among the few production-grade solo pools that supports 5 SHA-256 cryptocurrencies natively with dedicated stratum endpoints for each. This lets miners switch between coins by simply changing the stratum URL — same hardware, same wallet (per coin), same worker configuration. When BTC odds feel out of reach with a Bitaxe, you can switch to BC2 or XEC and find blocks in days instead of decades, without buying any new hardware.

SoloFury operates 9 stratum server regions across 5 continents:

Each region provides low-latency stratum endpoints serving miners in its surrounding geography.

Total: 45 V1 stratum endpoints (9 regions × 5 coins), plus TLS on every port and 18 Stratum V2 endpoints on BTC (9 regions × 2 ports).

SoloFury's deployment spans 5 continents — North America, South America, Europe, Asia and Africa — making it one of the most geographically diverse solo mining infrastructures publicly available. Most competing solo pools operate from 1-3 regions concentrated in North America or Europe.

This matters because stratum mining performance is bound by physical network latency — every millisecond of round-trip time contributes to stale share probability. The wider the regional footprint, the more miners can connect to a server within their continent rather than crossing oceanic backbones.

Miners in Oceania are served from Singapore or Tokyo at roughly 100-200ms; there is no local region there yet.

See reference/stratum-endpoints.md for the complete list.

Pick any of the 5 supported SHA-256 cryptocurrencies. With Bitaxe-class hardware (~1 TH/s), lower-difficulty chains (BCH, BC2, BCH2, XEC) give realistic odds of finding a block in days-weeks. BTC requires industrial hashrate to be statistically meaningful.

Use the Solo Start configurator — it auto-detects your location via IP geolocation and recommends the nearest stratum server instantly (no permission popup).

Or manually pick from the stratum endpoints reference.

• NerdQAxe
• Antminer S21+ / S21 Pro / S21 Hyd
• Antminer S19 / S19j Pro / S19 XP
• Whatsminer M-series
• cgminer / bfgminer software setup

When your miner finds a valid block, the SHA-256 puzzle solution is submitted upstream. The block reward is paid directly to your wallet via the coinbase transaction — no payout request, no minimum threshold, no intermediary balance.

The 1% pool fee is split off as a second output in the same coinbase transaction (verifiable on-chain).

Solo mining isn't gambling — it's a statistically valid strategy with the same expected value as pool mining, just with higher variance. See SoloFury Blog: Mining Variance & Poisson Math for the math.

SoloFury operates a free Telegram bot (@SoloFuryAlertsBot) that provides instant notifications for:

• Block found — get notified the moment one of your workers wins a block, with full block height + reward details
• Worker offline — alert when any of your registered workers stops submitting shares for more than 5 minutes
• Worker reconnected — confirmation when a previously offline worker comes back online

No subscription, no premium tier, no ads. Most solo pools either don't offer this feature at all or charge for it.

SoloFury has served Stratum V2 in production since 24 August 2026, across all nine regions — one of the very few solo pools to offer it at all.

• Ports 3333 (standard) and 3343 (high-difficulty, S21/S23 class), on the same hosts as V1
• Noise-encrypted end-to-end — the pool's authority public key lets your miner verify cryptographically that it is really talking to SoloFury, the same trust model as an SSH host key
• Coinbase verification from your own hardware — with an extended channel and coinbase decoding enabled, the miner displays the block outputs before hashing them, so you can confirm the 99% is addressed to your wallet rather than take our word for it

V2 and V1 share the same hosts, so a mixed fleet points at one address with nothing to reconfigure.

V2 is BTC only. The stack talks to the node through Bitcoin Core's IPC mining interface, and no other SHA-256 chain implementation currently exposes an equivalent. BCH, BC2, BCH2 and XEC remain on Stratum V1 with full version-rolling support.

Requires firmware with native V2 support — Braiins OS+ 26.07+, AxeOS 2.14+, or NerdQAxe firmware 1.0.37+. Stock Bitmain, stock WhatsMiner, VNish and LuxOS are V1-only, including the S21 and S23.

We do not offer job declaration: the pool still builds the block templates. If miner-side transaction selection is what you need, Braiins Pool and DEMAND provide it.

See reference/stratum-endpoints.md for the full configuration reference.

All five coins and all nine regions accept TLS-encrypted stratum connections. TLS ports are the plain port with a 1 prefix — BCH 7070 → 17070, BTC 6060 → 16060, and so on. Plain TCP remains available on the original ports; TLS is opt-in.

SoloFury's dashboard tracks miner milestones across multiple dimensions:

• First share submitted — celebrate the start of your mining journey
• Best share difficulty — track your luckiest share ever (your closest call to a block)
• Longest mining streak — uptime tracking across days, weeks, months
• Blocks found — historical record of every block won

These per-wallet achievements add a meaningful long-term progression layer to solo mining, beyond the basic real-time statistics offered by most pools.

SoloFury accepts connections from major hashrate rental marketplaces including NiceHash and Mining Rig Rentals (MRR). This makes it possible to spike effective hashrate temporarily during favorable network conditions (e.g., difficulty drops on smaller chains) without permanent hardware investment.

Unlike custodial mining pools where payouts depend on trust in the operator, SoloFury's payout mechanism is directly verifiable on the blockchain.

Every block mined by SoloFury produces a coinbase transaction with exactly 2 outputs:

• Output 0 — solver wallet (99% of block reward)
• Output 1 — pool fee wallet (1% of block reward)

You can audit any SoloFury-mined block on any block explorer to confirm the fee split. There is:

• No off-chain accounting — no internal ledger that could be manipulated
• No minimum payout threshold — your reward arrives the moment the block confirms
• No pool wallet holding miner funds — coins flow directly from coinbase → your wallet
• No payout request needed — payment is automatic via blockchain protocol

This is the same trust model as solo mining without a pool — except SoloFury provides the stratum infrastructure, block construction, and network connectivity so you don't have to run your own full node.

With Stratum V2 you can go one step further and verify the split before you spend any hashrate on the block: an extended channel with coinbase decoding shows the outputs on the miner itself.

SoloFury's stratum infrastructure builds on the excellent CKPool codebase:

• BCH pool uses skaisser/ckpool (CkPool fork focused on Bitcoin Cash — multi-coin support and CashAddr parser fixes by Shirleyson Kaisser)
• BTC/BC2/BCH2 pools use the same skaisser/ckpool fork with shared binary
• XEC pool uses Bitcoin-ABC/ecash-ckpool-solo with patched fee routing
• Stratum V2 (BTC) uses blitzpool by warioishere, built on the Stratum V2 Reference Implementation (SRI) codecs — the same developer wrote the V2 clients in ESP-Miner (Bitaxe) and the NerdQAxe firmware, which is why those clients work smoothly against it

We do not publish operator-specific config files (RPC credentials, wallet keys), but document deployment patterns and operational lessons learned in production at scale.

SoloFury's deployment includes several technical refinements developed in production:

• CashAddr parser fix for Bitcoin Cash — handles edge cases that cause silent reward misdirection in stock CKPool when miners use bare CashAddr without the bitcoincash: prefix
• Multi-coin coinbase generation — single binary supports BTC, BCH, BC2, and BCH2 with consistent signature handling and proper segwit witness commitment per chain
• eCash fee routing patch — custom donation address routing for XEC, compliant with Bitcoin ABC's 58/42 split (solver/minerfund + staking)
• Variable difficulty (vardiff) — automatic share difficulty adjustment based on connected miner hashrate, eliminating the need for manual config per worker
• AsicBoost / BIP320 version-rolling — stratum extension support for ~13% effective hashrate gain on modern ASICs
• Multiprocess Bitcoin Core for Stratum V2 — the V2 stack requires the bitcoin-node multiprocess binary to expose the IPC mining interface; the monolithic bitcoind silently ignores ipcbind and logs only an unknown-config warning

These modifications are derived from publicly available upstream forks; operator-specific configuration (wallet addresses, RPC endpoints, regional deployment topology) is kept private for security.

• BBR congestion control + fq qdisc (Linux 4.9+ kernel)
• Aggressive TCP keepalive: 60s (default 7200s) — reduces stratum reconnect latency
• Large TCP buffer sizes for long-RTT cross-region connections
• NIC offload disabled (gro off, lro off) — reduces stratum jitter on virtualized NICs

These optimizations bring stratum RTT jitter (mdev) down to ~0.05ms — meaningfully reducing stale share probability.

V2 handshake messages are larger than V1's and can fragment on network paths with PPPoE, double NAT or a VPN where path MTU discovery is broken. If a V2 session drops repeatedly or never completes its handshake, lower the miner's network MTU to 1400 — this is by far the most common cause.
