ViaBTC uses PPS+ (Pay Per Share Plus) as its default mining pool payment method and also supports PPLNS (Pay Per Last N Shares). PPS+ calculates the block subsidy component using PPS rules and distributes transaction fees using PPLNS rules. Under PPLNS, both components depend on blocks the pool actually finds.
These payment methods determine how mining earnings are calculated and credited to your ViaBTC account. Withdrawal settings determine when and how an eligible balance moves out of that account.
ViaBTC’s Payment Methods at a Glance
For Bitcoin, a block reward consists of the block subsidy—the newly issued BTC—and transaction fees. ViaBTC’s fee table labels the subsidy component “Block Reward.” This article uses “block subsidy” to distinguish it from transaction fees.
| Feature | PPS+ | PPLNS |
|---|---|---|
| Block subsidy component | Calculated from valid shares under PPS rules | Allocated from actual pool-found blocks under PPLNS rules |
| Transaction fees | Distributed under PPLNS rules | Distributed under PPLNS rules |
| Listed pool fees | 4% on the subsidy component; 2% on transaction-fee earnings | 2% on both components |
| Exposure to pool luck | Applies to the transaction-fee component | Applies to both components |
These are ViaBTC’s published standard fees at the time of review. Check the selected coin’s available methods and the current fee schedule before choosing a payment method.
How PPS+ Works
PPS+ combines two ways of calculating mining income.
The block subsidy component uses PPS, or Pay Per Share. A valid share is submitted work that meets the pool’s share target and helps measure a miner’s contribution; it does not necessarily qualify as a network block. ViaBTC calculates this component from valid shares using the current network difficulty and settles it hourly, deducting the listed 4% fee. Payment for this component does not depend on whether the pool finds a block during that hour.
The transaction-fee component uses PPLNS. It depends on transaction fees from blocks the pool actually finds. ViaBTC’s published rules specify allocation according to the miner’s contribution over the past five difficulty rounds, after the relevant block receives six confirmations, with a 2% fee deducted. See ViaBTC’s earnings calculation rules.
PPS+ therefore reduces exposure to pool luck for the subsidy component, but it does not make total mining income fixed. Submitted work, network difficulty, and transaction-fee earnings can still change.
The two fee percentages are not added together to make 6%. Each applies to a different earnings component, so the effective fee rate across total earnings depends on the mix of those components.
How PPLNS Works
Under PPLNS, both the subsidy and transaction fees are allocated from blocks the pool actually finds. ViaBTC applies a listed 2% pool fee to this income.
For each qualifying block, the miner’s allocation is based on their contribution over ViaBTC’s stated lookback window: the past five difficulty rounds. Distribution follows the six-confirmation condition. The lookback window measures contributed work; the found block provides the reward being allocated.
PPLNS earnings fluctuate with pool luck—whether the pool finds more or fewer blocks than statistically expected for its contributed work. This affects both earnings components, whereas PPS+ exposes only its transaction-fee component to this source of variation.
Settlement Timing Is Different from Withdrawal Timing
Hourly PPS settlement means earnings are credited within ViaBTC. It does not mean BTC is sent to an external wallet every hour.
For BTC Auto Withdrawal to an external address, ViaBTC currently lists a 0.001 BTC minimum, with processing once daily between 10:00 and 18:00 (GMT+8) when the applicable conditions are met. This processing window is separate from confirmation of the withdrawal transaction on the Bitcoin network.
Auto Withdrawal also offers two payout modes:
- Account balance: Pays the eligible account balance when the minimum payout condition is met.
- Daily earnings: Reserves mining earnings settled on the payout day and pays eligible earnings accumulated from previous complete calendar days, subject to the payout conditions.
The mode therefore affects the amount eligible for withdrawal, as well as the applicable conditions. It does not change how PPS+ or PPLNS calculates mining earnings. See the Auto Withdrawal documentation for setup and current requirements.
For example, a BTC miner using PPS+ may see hourly subsidy credits in their ViaBTC account while their external wallet balance remains unchanged. Auto Withdrawal is processed separately, and the eligible amount must meet the configured payout conditions.
Choosing Between PPS+ and PPLNS
The main trade-off is between exposure to pool luck and the fee charged on the subsidy component.
With PPS+, the subsidy component is paid for valid work independently of the pool’s short-term block discoveries. Its listed fee is 4%, while transaction-fee earnings carry a separate 2% fee and remain dependent on actual pool-found blocks.
With PPLNS, both components depend on actual pool-found blocks and carry a listed 2% fee. The lower subsidy-component fee is a cost difference to weigh against more variable earnings; it does not guarantee a higher realized payout over a particular period.
Compare these mechanics with the payout variability you are prepared to manage, and confirm the available options for your selected coin.
FAQ
What is the default payout method on ViaBTC?
PPS+ is ViaBTC’s default payment method. ViaBTC also supports PPLNS; check the options available for your selected coin.
Does PPS+ pay out every hour?
Its PPS subsidy component is settled hourly within the pool account. Transaction-fee earnings follow PPLNS rules, and external withdrawals follow separate settings and timing.
Is the PPS+ fee 6%?
No. The listed 4% fee applies to the subsidy component, while 2% applies to transaction-fee earnings. The percentages apply to separate amounts and are not added together.
Is SOLO still available on ViaBTC?
No. ViaBTC discontinued its SOLO payment method for all coin pools on May 20, 2026 (UTC+8). Existing SOLO users were switched to PPS+ where supported, or PPLNS otherwise, according to the official announcement.
What is the minimum BTC Auto Withdrawal amount?
The published minimum for Auto Withdrawal to an external BTC address is 0.001 BTC. This is specific to that withdrawal feature, not a minimum for earning or receiving internal mining credits.
