FirePool Overseer's Guide - Pool Rules, Rewards & Mining Reference

◈ Welcome to FirePool

FirePool is a community mining pool built for Dwellers of all sizes — from a lone NerdMiner ticking at 80 KH/s to a full ASIC installation pushing terahashes. We run ten SHA-256 coins across both cooperative (PROP) and lone-wanderer (SOLO) modes, all on a flat 0.5% fee.

This guide covers the rules of the Vault, how rewards are calculated and paid out, which port to connect on, and everything else you need to operate in the Wasteland like a seasoned survivor. For the interactive config generator — where you pick your coin, mode, and device and get your exact stratum string — head to Pip-Boy Config.

◈ Mining Modes — PROP vs SOLO

☢ PROP — Cooperative

Every Dweller in the pool contributes shares toward finding a block. When a block is found, the reward is split proportionally among all miners based on the share work each submitted during that round.

Steady, predictable income
Great for smaller rigs and NerdMiners
Everyone wins when anyone finds a block
Reward scales directly with your hashrate

☢ SOLO — Lone Wanderer

You mine entirely on your own. If your miner finds a block, you keep 99.5% of the full block reward. If someone else finds one, you receive nothing for that round.

High-variance, lottery-style payouts
Best for high-hashrate setups
Full block reward goes to the finder
0.5% pool fee taken at payout

Which mode should I use? If your hashrate is under ~1 TH/s on a SHA-256 coin, PROP is almost always better — you'll see regular payouts without waiting months for a lucky block. SOLO is more worthwhile the higher your hashrate, or if you enjoy the lottery aspect regardless of hashrate.

◈ How PROP Rewards Are Calculated

When a block is found, Miningcore tallies every share submitted in that round and pays each miner in proportion to their difficulty-weighted contribution:

                    Your Payout = (Your Share Difficulty Sum / Total Round Difficulty) × Block Reward × 0.995
                

Block Reward is the full coinbase value — subsidy plus transaction fees — as reported by the coin's node.
0.995 reflects the 0.5% pool fee deducted before distribution.
Shares are difficulty-weighted: a share at diff 512 counts twice as much as one at diff 256. VarDiff adjusts your share difficulty automatically so all miners contribute fairly regardless of hashrate.

Round reset: Shares only count within the round they were submitted. A new round starts immediately after each block is found. Shares from the previous round do not carry over.

◈ Fees & Payout Thresholds

Flat 0.5% fee on all pools and all modes. No hidden charges, no withdrawal fees, no registration required.

Coin	Pool Fee	Minimum Payout	Confirmations Required
BC2	0.5%	0.01 BC2	20
BTC	0.5%	0.01 BTC	20
BCH	0.5%	0.01 BCH	20
DGB	0.5%	1.0 DGB	20
DGB-S	0.5%	1.0 DGB	20
BTCS	0.5%	0.01 BTCS	20
XEC	0.5%	10,000 XEC	20
LTC	0.5%	0.1 LTC	20
BCH2	0.5%	0.01 BCH2	20
NMC	0.5%	0.01 NMC	20
PPC	0.5%	0.5 PPC	20

How payouts work: When a block is found, it enters a pending state. After the coin network reaches 20 confirmations, the block is confirmed and each miner's balance is credited. Actual coin transfer happens automatically the next time your accumulated balance meets or exceeds the minimum payout threshold above.

SOLO payouts: In SOLO mode, the full block reward (minus 0.5%) is credited to the miner who found the block after 20 confirmations. This can be a large single payment. The minimum payout threshold still applies — if somehow the single block reward is below threshold (extremely rare for any major coin), it will accumulate until the threshold is met.

◈ VarDiff & Choosing Your Port

VarDiff (Variable Difficulty) automatically adjusts the share difficulty your miner receives so you submit shares at a steady rate — roughly every 30 seconds — regardless of your hashrate. This is how a 200 GH/s BitAxe and a 10 TH/s ASIC can both mine on the same standard port without one overwhelming the pool or the other going idle.

Port Suffix	Type	Difficulty Range	Best For
x333 / x339	Standard VarDiff	256 — 500,000	Any device — NerdAxe, BitAxe, single ASICs, multi-ASIC farms
x334	NerdMiner Fixed	0.1 — 256	NerdMiner, ESP32, any device under ~500 MH/s
x337	High-Hash Farm	500,000 — 50,000,000	Large ASIC farms with combined hashrate over ~70 TH/s
x338	Ultra-Farm	50,000,000+	Industrial-scale operations only
x336	▲ TLS PROP	Same as x333	Encrypted uplink for ASIC miners — use `stratum+ssl://`
x346	▲ TLS SOLO	Same as x339	Encrypted solo uplink — use `stratum+ssl://`

Not sure which to use? Use x333 (PROP) or x339 (SOLO). VarDiff will handle everything automatically for you. Only upgrade to x337 if you run a large farm (50+ TH/s combined) and see excessive stale shares on x333.

The x prefix is the coin identifier: 3=BC2, 4=BTC, 5=BCH, 6=DGB, 7=BTCS, 9=XEC, 2=LTC, 1=BCH2.

◈ Connection Format

All miners connect using the standard stratum protocol. The format is the same across all coins and devices:

Host:    stratum+tcp://firepool.ca:PORT
User:    WALLET_ADDRESS.worker_name
Pass:    x

WALLET_ADDRESS — your receive address for the coin you are mining. Do not use an exchange address.
worker_name — any label for your rig (e.g. bitaxe1, asic-rig). 1–15 characters, no spaces. Optional but strongly recommended so you can identify each machine in the dashboard.
Password — always x. The pool does not use passwords for authentication.

▲ ENCRYPTED UPLINK — TLS (OPTIONAL)

For miners that support SSL/TLS, FirePool offers dedicated encrypted ports. Connect using stratum+ssl:// and your coin's x336 (PROP) or x346 (SOLO) port. Everything else stays the same.

Host:    stratum+ssl://firepool.ca:x336  (PROP) or x346 (SOLO)
User:    WALLET_ADDRESS.worker_name
Pass:    x

TLS is supported by most modern ASICs and mining software. NerdMiners and BitAxe do not support TLS — use the standard x333 / x334 ports for those devices. TLS is available for BC2, BTC, BCH, DGB, BTCS, and LTC.

Use the Pip-Boy Config generator to get your complete, ready-to-paste stratum string for any coin, device, and connection type.

◈ Address Formats

FirePool's Vault automatically accepts multiple address formats for coins that support them. You do not need to convert your address manually.

Coin	Accepted Address Formats
BC2	Legacy (1...) format
BTC	Legacy (1...), SegWit (3...), Bech32 (bc1...)
BCH	CashAddr (`bitcoincash:q...`), legacy (1...), short CashAddr (`q...`)
DGB	Legacy (D...), SegWit (S...), Bech32 (dgb1...)
DGB-S	Legacy (D...), SegWit (S...), Bech32 (dgb1...) — same wallet as DGB
BTCS	Bech32 (bs1...)
XEC	CashAddr (`ecash:q...`), short CashAddr, legacy (1...)
LTC	Legacy (L...), SegWit (M...), Bech32 (ltc1...)
BCH2	CashAddr (`bitcoincashii:q...`)

◈ Pool Rules

☢ Vault Directive — Read Before Connecting

One wallet address per miner, multiple workers allowed. You can run as many machines as you like under the same wallet address using different worker names (wallet.rig1, wallet.rig2, etc.).
Use your own wallet address. Never use an exchange deposit address — payouts to exchange addresses are frequently lost, and we cannot recover them.
No proxy abuse. Do not run a large undisclosed proxy through a single connection. If your combined farm hashrate exceeds 70 TH/s on one port, please use the farm port (x337) to avoid stale shares.
No intentional duplicate shares or manipulation. Detected attempts to exploit the share submission system will result in immediate ban.
Be a decent Dweller. This is a community pool. Treat other miners and the admins with respect in Discord and the Facebook group.
Unclaimed balances. Balances below the minimum payout threshold remain in your account indefinitely — they will be paid out whenever your accumulated balance crosses the threshold. There is no expiry on balances.
Pool is not responsible for network issues — orphaned blocks, blockchain reorganizations, or node outages are outside our control. Orphaned blocks do not pay out.

◈ Vault Clearance Levels

The pool leaderboard on the home page assigns Vault-Tec clearance titles based on your rank among active miners for the selected coin:

Rank	Title	Description
#1	[OVERSEER]	Top contributor — commands the Vault
#2	[SENTINEL]	Second in power — keeps the Vault safe
#3	[KNIGHT]	Third — a proven Wasteland warrior
#4–6	[DWELLER]	Active contributor to the pool
#7+	[INITIATE]	Building up share count

Rankings reset with each coin selection and reflect active hashrate at the time of the leaderboard refresh.

◈ Frequently Asked Questions

► My miner is connected but not showing in the Dweller Terminal. Why?

The dashboard updates every few minutes. If your miner just connected, give it 5–10 minutes. Also confirm you are searching with the correct wallet address and the correct coin selected. Share data is tracked per-coin, so a BC2 miner won't show under BTC stats.

► When will I get paid?

In PROP mode: when the pool finds a block AND your accumulated balance meets the minimum payout threshold for the coin. In SOLO mode: if you find a block. In both cases, there is a 20-block confirmation wait after the block is found before the balance is credited. Payments are processed automatically — no action required on your part.

► My hashrate shows in the pool but I never seem to get paid. What's wrong?

Check your accumulated balance in the Dweller Terminal. If your balance is below the minimum threshold, it hasn't been paid out yet — it will pay automatically when the threshold is met. On lower-volume pools, blocks may be infrequent; your balance increases each time a block is found.

► I sent to an exchange address by mistake. Can you recover my payment?

No. Once a payment is broadcast to the network it cannot be reversed or redirected. Always use a personal wallet address (one where you control the private keys) to receive mining rewards.

► What is the pool hashrate and how often does it find blocks?

Check Vault Status for current pool hashrate and recent block history. Block frequency depends on the pool's combined hashrate relative to the network — higher pool hashrate means more frequent blocks.

► Can I mine multiple coins at the same time?

Yes — point different rigs to different coin ports. Each coin is tracked independently. You can mine BC2 on one machine and DGB on another simultaneously, each with its own balance.

► My NerdMiner keeps disconnecting. Which port should I use?

Use the NerdMiner port (x334 for your coin). For example, BC2 NerdMiner → port 3334. These ports use ultra-low fixed difficulty (starting at 0.1) designed for the low hashrate and limited connection stability of ESP32-based devices.

► Where do I get a wallet for these coins?

See the Wallet Resources section below.

◈ Wallet Resources

Always use a wallet where you control the private keys. Never mine directly to an exchange — they frequently reject or lose mining payouts.

Coin	Recommended Wallet
Bitcoin II (BC2)	github.com/Bitcoin-II
Bitcoin (BTC)	bitcoin.org/choose-your-wallet — Electrum, Sparrow, or hardware wallet
Bitcoin Cash (BCH)	bitcoincash.org/wallets — Electron Cash, Bitcoin.com Wallet
DigiByte (DGB)	digibyte.org/wallets — Official DigiByte Core or Go wallet
Bitcoin Silver (BTCS)	BTCS Core wallet
eCash (XEC)	cashtab.com — Official eCash web wallet
Litecoin (LTC)	litecoin.org — Litecoin Core, Electrum-LTC
Bitcoin Cash II (BCH2)	BCH2 Core wallet
