Bitcoin mining has come a good distance because the days of GPUs and basement set ups. In that point, miners have superior in numerous methods. For instance, ASICs at the moment are the usual, not GPUs. Moreover, enterprise grade gamers have entered the sphere, opening new frontiers and bringing with them the scale and institutional recognition that opens the doorways to in any other case unreachable locations for smaller miners. These days, the mining panorama is one the place grid providers, curtailment methods, and power market participation are now not edge circumstances however core methods. Because the world round it has moved ahead, there’s one query we preserve listening to from miners: can PPLNS adapt?
Many miners, notably these working carefully with power suppliers or integrating Demand Response mechanisms, have come to view PPLNS with suspicion. They fear that it penalizes downtime and rewards solely uninterrupted hashrate—a foul deal for individuals who routinely curtail machines to assist the grid or present different providers.
This worry isn’t baseless. It traces again to a pivotal second within the mining trade’s latest previous, one which apparently sealed the deal for a lot of on PPLNS model payouts: the fallout between RIOT and Braiins Pool.
On the time, Braiins was utilizing the Rating payout system. Designed in 2011 by Slush himself, Rating was engineered to unravel the issue of pool hopping—when miners would leap between swimming pools to take advantage of reward techniques. There’s additionally been a false impression that Rating is a PPLNS model fee system, however as Rosenfeld’s bible on pool payout techniques describes, Rating and PPLNS are distinctly totally different payout strategies. The primary distinction is how they account for shares, particularly, Rating carried out a rolling window with exponential decay perform, this successfully made the lookback window very brief. Then again, PPLNS is a household of payout techniques with varied forms of mounted size lookback home windows.
As proven on this archived web site of how Rating labored, you may see that after 90 minutes your hashrate had no extra presence on the pool. Which means the second a miner begins mining, their share of rewards pretty rapidly reaches the truthful worth of the hashrate. Then again, when a miner stops mining, it drops equally quick, as proven on the gif beneath.
This may need labored properly within the period of cowboys and hackers, however it was by no means designed with in the present day’s advanced mining environments in thoughts. Actually not with Demand Response, the place miners deliberately and profitably take machines offline to stabilize power grids or bid into ancillary markets. To Rating, that form of habits appears to be like no totally different than a pool hopper—somebody making an attempt to cheat the system.
So when RIOT left Braiins, citing considerations about payout mechanics, it despatched a shockwave via the mining world. As a result of aforementioned false impression, Rating system’s flaws received unfairly projected onto a broader class of payouts, PPLNS received caught within the fray, catching a stray bullet within the course of, and the trade collectively threw the child out with the bathwater.
However the mining world has modified, and it’s time for the phoenix to rise from his ashes.
SLICE: A Payout Mechanism for the twenty first Century Grid
Enter SLICE, a contemporary, open-source Stratum-V2-ready payout system created by the DMND group. It’s an enchancment and evolution of PPLNS, that rethinks how miners receives a commission, rewards are calculated, and —most significantly— how downtime is handled respect
to Rating. All whereas preserving miner’s proper to construct their very own block templates with SV2.
At its core, SLICE is about equity and transparency. It preserves the foundational concept of PPLNS—paying miners in proportion to their precise contribution to fixing blocks—whereas modernizing it for in the present day’s decentralized mining panorama.
The important thing innovation lies in how SLICE buildings reward calculation, and on how the lookback window works. Reasonably than treating the complete pool as a monolith, SLICE breaks time into smaller, dynamic “slices” of labor to correctly distribute the payment part. These slices signify batches of shares submitted over a particular interval, the place we management for the quantity of charges within the mempool, and examine and rating totally different job templates for the monetary worth they signify. When a block is discovered, SLICE distributes the block subsidy and transaction charges individually. The subsidy is allotted proportionally by hashrate, whereas the charges are distributed primarily based on hashrate and monetary worth.
That is notably related in a world the place miners can select their very own transaction units. Some miners might prioritize high-fee MEV-style bundles; others might exclude sure forms of transactions for ideological, political or technical causes. SLICE ensures that, inside every slice, miners are rewarded in accordance with each the amount and high quality of their work—with out punishing them for downtime or strategic power selections. For these curious to study extra, this text can show useful.
Demand Response With out Penalty
What makes SLICE particularly enticing for miners taking part in Demand Response or curtailment packages is that it doesn’t penalize you for being offline.
That’s as a result of SLICE doesn’t decay your payout simply since you took a break. Your shares stay within the PPLNS window—the rolling window of latest work that’s eligible for payouts—so long as they’re latest sufficient. On this approach, every share is handled independently, and is anticipated to get 8 payouts, since SLICE makes use of an 8-block rolling window, every legitimate share stays eligible for payout throughout the following 8 blocks on common. Which means no matter how massive or small the pool is, you’ll by no means have the abysmal luck of consuming up dangerous luck days with out a block, disconnecting, having the pool discover a block, and never receives a commission.
Which means miners can energy down throughout peak demand hours, assist their regional grid, and nonetheless acquire their truthful minimize from blocks discovered after they resume operations, most significantly, even whereas they’re offline, if their shares are nonetheless within the window. In different phrases, if the pool has a streak of dangerous luck, after which the miner is known as to carry out demand response and shuts off, even when the pool finds a block throughout their down time, that miner will receives a commission their justifiable share for on a regular basis they had been on-line. That’s as a result of every share generated throughout that point might be lively and getting paid for 8 blocks on common.
This isn’t a workaround. That is the characteristic. It makes SLICE totally suitable with trendy power methods that require flexibility, whether or not you’re taking part in frequency regulation markets, ramping down throughout grid emergencies, or just optimizing for off-peak pricing.
For instance, let’s say {that a} miner is mining at a pool, and the pool hasn’t discovered that day’s block but. Which means the pool hasn’t discovered the block but, and thus the miners hasn’t gotten paid for that day but. Now, the miner shuts off to offer ancillary providers throughout peak summer season load for just a few hours, throughout that point, the pool finds the block. In a Rating primarily based pool, the miner wouldn’t see a single Sat of that after 90 minutes, when the decay has had full impact. However even when the pool discovered a block half-hour later, because of the exponential decay, the miner would barely see something. Then again, the miner would have all the shares they mined over the day obtain a fee, since every share receives on common 8 funds. Thus, the miner would profit within the good occasions, and never be penalized within the dangerous occasions.
Cost Transparency and Auditability
Moreover, SLICE doesn’t simply modernize payout equity—it does so in a approach that minimizes belief within the pool operator. Each slice is totally auditable. Every share is tracked, listed, and publicly verifiable by any miner, so miners can independently confirm their share of the block reward. There’s no black field, no “belief me bro.”
And if the pool operator makes an attempt to cheat—say, by injecting faux shares to dilute payouts—miners can problem the integrity of the slice. The Job Declaration extension to Stratum V2, which SLICE depends on, consists of mechanisms for publishing share knowledge, verifying Merkle roots, and guaranteeing that every share corresponds to actual computational work.
For miners who care about decentralization, SLICE isn’t only a fee scheme—it’s an accountability software.
From Defensive to Strategic
The shift from Rating to SLICE represents greater than a technical improve. It’s a psychological shift. Mining swimming pools now not have to defend towards dangerous actors by penalizing everybody. As a substitute, they’ll construction payouts in a approach that displays actuality: that miners are refined members working not solely within the Bitcoin blockchain, but in addition the power ecosystem.
With SLICE, PPLNS stops being a legal responsibility and turns into a strategic benefit. It allows higher income seize, extra transparency and auditability, and smoother integration with grid providers.
And in a world the place uptime is non-compulsory, however equity is non-negotiable, that’s precisely what enterprise-grade miners want, a strategic pool companion that pushes ahead and innovates, bringing the long run in the present day and enabling miners to earn more money with the identical {hardware}.
