What Do ViaBTC Mining Statistics Reveal About Pool Performance?

A useful reading of ViaBTC’s Bitcoin mining statistics comes from comparing several figures at the same time. ViaBTC’s current BTC statistics page reports 99.73% total luck, 92.02% 30-day luck, 52,780 total blocks, 19 orphan blocks, and a 0.03% orphan rate. Its payment page lists PPS+ with a 4% fee on the PPS block-reward component and a 2% fee on the separately distributed transaction-fee component, while PPLNS applies a 2% fee to block rewards and transaction fees together. These figures show how pool size, block discovery, orphan frequency, payout rules, and network conditions affect a miner’s observed results.

ViaBTC’s published statistics give miners several numbers that can be read together: total blocks, orphan blocks, orphan rate, short-term luck, long-term luck, block runtime, block reward, and hashrate. A BTC pool with 52,780 recorded blocks and only 19 orphan blocks reports an orphan rate of 0.03%, while its total luck sits at 99.73%. Those two figures describe different parts of pool performance: one concerns how often found blocks fail to remain on the accepted chain, while the other compares observed block production with statistical expectation.

“Total luck” is more useful over a large sample than over a few days.

The difference can be seen in ViaBTC’s own recent block records. On September 3, 2026, its public table showed one block with a runtime of 4 minutes 45 seconds and a reported luck value of 2,554.37%, followed later by blocks with runtimes of 4 hours 49 minutes 50 seconds and 5 hours 6 minutes 39 seconds, carrying luck readings of 35.87% and 30.46%. The same pool can therefore show very high and very low short-term readings within a single day.

Those numbers come from the probability of finding a Bitcoin block, not from a schedule that guarantees one block every fixed number of minutes. A pool can find two blocks within less than 10 minutes and then wait several hours for another. Looking only at the latest block runtime would give a distorted picture, while a history containing thousands of blocks provides a much larger sample for judging whether actual production is broadly aligned with expected production.

The 0.03% orphan rate deserves separate attention because it is not a measure of luck. ViaBTC currently reports 19 orphan blocks out of 52,780 total BTC blocks on its statistics page. That is roughly one orphan for every 2,778 recorded blocks, based on the published counts. A low rate is consistent with effective block propagation and network connectivity, although the public figure by itself cannot isolate the contribution of every infrastructure component.

Block propagation matters because finding a valid block first is only part of the process. When two miners find competing blocks at nearly the same time, the network must receive and relay those blocks before another competing branch becomes accepted. A pool that regularly reports a low orphan share has fewer recorded blocks that later failed to remain in the main chain, which is useful information when comparing infrastructure records across long periods.

Pool luck should be read on several time horizons. ViaBTC currently lists 30-day luck at 92.02% and total luck at 99.73%. The gap is substantial: the 30-day figure is 7.98 percentage points below the 100% expectation level, while the historical value is only 0.27 percentage points below it. The two readings can both be true because a shorter sample is more affected by random block timing than a much larger historical sample.

A simple way to read the published figures is:

 

This table also shows why comparing pools by one percentage can be misleading. A 92.02% reading does not mean that the pool is operating at 92.02% technical efficiency. It says that the observed number of blocks over the stated window was below the statistical expectation used by the pool’s luck calculation. A separate figure such as 0.03% orphan rate addresses a different operational question.

The payment method determines how much of this block-production variance reaches an individual miner. ViaBTC currently lists PPS+ and PPLNS, with PPS+ as the default. Under PPS+, the block-reward component uses PPS accounting and the transaction-fee component uses PPLNS distribution. The published fee is 4% for the PPS block-reward component and 2% for the transaction-fee component. Under PPLNS, the published fee is 2% for the combined block-reward and transaction-fee distribution.

The distinction can be illustrated with a simplified 100-unit block-reward example. Under a 4% fee on the PPS-settled block-reward component, 96 units remain before considering the separately handled transaction-fee component. Under a 2% PPLNS fee, 98 units remain from the same 100-unit gross amount, but the actual payout depends on the pool finding a block and on the miner’s share during the specified measurement period. This is why the two percentages should not be read as a simple “4% versus 2%” contest.

ViaBTC states that PPS+ pays according to valid shares and the current difficulty, with the block-reward portion paid hourly. For PPLNS, the pool calculates the payout from the miner’s share of pool hashrate over the last 5 difficulty rounds after a block receives 6 confirmations.

That six-confirmation rule changes the timing of observed income. A miner using PPLNS can submit a large amount of valid work and still see the corresponding payout depend on when a qualifying block is found and confirmed. The same miner under PPS+ receives the block-reward component through the pool’s share-based calculation, so short periods of low pool luck are less directly reflected in that component of the payout.

The current ViaBTC Pool Fees page also reports an estimated BTC average daily earning of 0.00000048 BTC per TH/s under PPS+, based on the previous 7 days, and describes the figure as an estimate rather than a guaranteed payment.

The seven-day basis matters because it places a time limit on the number. A miner seeing 0.00000048 BTC per TH/s should not treat that amount as a fixed annual rate. Network difficulty can change, transaction-fee income can change, BTC market price can change, and pool conditions can change. Even without a change in machine efficiency, the amount of BTC associated with each unit of hashrate can move over time.

Network difficulty also has to be separated from pool performance. If two miners each provide 100 TH/s, but the Bitcoin network difficulty rises materially during the comparison period, both machines may produce fewer BTC per unit of hashrate even when the pool is functioning normally. Pool statistics therefore work best when the dates, difficulty conditions, payment method, and measurement window are aligned.

ViaBTC’s 2026 published guidance also states that actual mining income can be affected by difficulty, transaction-fee conditions, hashrate, pool luck, and market conditions. That is consistent with the structure shown on its calculation page, where the block-reward component and transaction-fee component are treated separately under PPS+.

A miner reviewing ViaBTC statistics can therefore use a compact four-part check:

• Scale: compare pool hashrate with total network hashrate.
• Production: compare actual block counts with expected production over a long sample.
• Propagation: examine orphan blocks and the reported orphan rate.
• Payout: compare PPS+, PPLNS, fee rates, and settlement timing.

The order matters because a large pool can have a poor short-term luck reading without having poor infrastructure. Likewise, a low fee can look attractive until the settlement method and variance exposure are included. A 2% PPLNS fee and a 4% PPS block-reward fee apply under different payout structures, so the percentages cannot be interpreted independently of the accounting method.

Recent block records provide a practical illustration of why longer observation windows are needed. On September 3, 2026, ViaBTC listed blocks at heights 965273, 965268, 965274, 965306, 965313, 965322, 965346, and 965381. The reported runtimes ranged from 4 minutes 45 seconds to 5 hours 6 minutes 39 seconds, while individual luck values ranged from 30.46% to 2,554.37%. Eight blocks from one displayed sequence already span more than two orders of magnitude in the luck readings.

That spread is also why a one-day ranking between pools can change quickly. Suppose Pool A finds an unusually early block while Pool B experiences a long block interval. Their displayed luck values may look very different even when both pools have similar hashrate quality and normal infrastructure. After several hundred or several thousand blocks, the influence of any single unusually fast or slow interval becomes much smaller.

The historical sample on ViaBTC is already large enough to make the long-term figure more informative than an isolated daily reading. With 52,780 BTC blocks reported, moving total luck from 99.73% to a materially different figure would require enough new blocks and a sustained difference in realized production to change a large accumulated sample. A seven-day statistic, by comparison, can shift much faster when only a limited number of blocks falls inside the measurement window.

Another useful distinction is between pool share and miner share. A pool can account for roughly one-tenth of the network while an individual miner contributes only a small fraction of that pool’s hashrate. Pool-level statistics tell the miner about the environment in which their shares are being processed, but they do not replace worker-level indicators such as accepted shares, rejected shares, stale shares, uptime, and effective hashrate.

That separation prevents an operational problem on one machine from being blamed on the pool. For example, if a miner’s configured hashrate is 100 TH/s but the pool consistently records only 92 TH/s while other workers are operating normally, the pool’s 99.73% lifetime luck does not explain the missing 8 TH/s. The relevant checks would instead include network connectivity, hardware temperature, firmware behavior, rejected shares, and the miner’s own runtime.

ViaBTC’s published calculations also show why transaction fees deserve separate attention. Under PPS+, the block-reward portion follows PPS while transaction fees follow PPLNS distribution, and the transaction-fee amount is explicitly described as variable. Under PPLNS, both block rewards and transaction fees are tied to the pool’s actual block-finding results.

A pool dashboard therefore gives a better picture when its numbers are treated as separate measurements rather than one overall performance score. The 99.73% historical luck figure speaks to long-run block production; the 0.03% orphan rate speaks to the fraction of recorded blocks classified as orphaned; the 52,780-block sample describes the scale of the historical observation; and the 4% and 2% fee figures describe different payment components and settlement structures.

For miners comparing ViaBTC with another pool in 2026, matching the measurement period is important. Compare 30-day with 30-day, not 30-day with lifetime; compare the same coin and reward system; use the same hashrate unit; and include the applicable fee structure. A pool showing 105% luck over a short period has not necessarily outperformed a pool showing 96%, just as a 2% fee does not automatically produce a higher realized payout than a 4% fee.

The statistics published by ViaBTC provide enough detail to make that comparison quantitative. A 0.03% orphan rate, 99.73% total luck, 52,780 recorded blocks, and 19 orphan blocks describe a very different information set from a dashboard that only reports current hashrate. Adding the 92.02% 30-day luck figure shows how recent conditions can differ from the long-run record, while the PPS+ and PPLNS rules explain how those pool-level conditions can be reflected in individual payouts.

For a miner, the most useful reading of ViaBTC statistics is therefore not whether one number is high or low. It is whether the historical block sample, recent luck, orphan rate, hashrate, difficulty environment, and payout method tell a consistent story. A long-run luck figure near 100%, a reported orphan rate of 0.03%, and tens of thousands of recorded blocks provide substantially more context than a single day of unusually fast or slow block discovery.
