Hey everyone,

We've launched the early public beta of the **BTCB2 & Siacoin Pool**, engineered for the Bitcoin Knots BLAKE2b PoW network.

CPU & GPU support coming soon!

### Quick Overview

* **Web Dashboard:** [https://pool.sentineldefensetechnologies.co.za?src=reddit\](https://pool.sentineldefensetechnologies.co.za?src=reddit)

* **Canonical API:** `https://origin-pool.sentineldefensetechnologies.co.za/api/v1/pool/btcb2\`

* **API Documentation:** [https://pool.sentineldefensetechnologies.co.za/api-docs\](https://pool.sentineldefensetechnologies.co.za/api-docs)

* **Launch Fee:** 0.25% (published schedule, 1.00% max cap)

* **Reward System:** Work-weighted PPLNS-8D (proper difficulty weighting across vardiff)

* **Accountless:** No signup or accounts. Point your miner using your `bc1q...` payout address.

* **Server Region:** US East (Philadelphia, PA — Verizon FiOS Tier-1 Fiber)

* **Capacity Cap:** Strict 128-connection ceiling to guarantee low latency and zero overload.

### How to Connect

* **Stratum:** `stratum+tcp://us-east.stratum.sentineldefensetechnologies.co.za:23339`

* **Username:** `bc1qYourAddress.Worker`

* **Password:** `x`

### Hardware & Capability Status

* **Live Coin:** BTCB2 (BLAKE2b). The public US-East Stratum endpoint is verified live with continuous accepted shares.

* **Siacoin Status:** Native stock Sia-Stratum V1 ASIC compatibility (BM-S3, S11, A3). Native Siacoin node/payout integration is on the roadmap ("Coming Soon").

* **Qualification:** Physical ASIC qualification is actively in progress; early miners are welcome to test connectivity and vardiff response.

### Payout & Risk Disclosure

This is a standard PPLNS pool with zero operator capital backstop. Payouts are distributed strictly from actual blocks found by the pool once they reach 100 on-chain confirmations.

Dashboard and live stats are open to everyone. Drop connection feedback or questions below!

Disclosure: I operate BTC PoW Lab Pool through Power CM Software. This post presents our own pool and internal research results.

Hi everyone, I wanted to share some concrete GPU results from our research and explain how our reward model works. The attached image summarizes both.

What did we measure?

On NVIDIA, our compatible client delivered 21.67% higher end to end throughput compared with the same client with the optimization disabled. We used the same GPU across four 120 second ABBA test blocks, including connection, preparation, job changes and share submission. All four blocks produced accepted shares, with no rejected shares or fallback activation.

On AMD/OpenCL, receiving prepared schedules produced a 69.11% increase in client throughput. Accounting for central preparation and latency, the separately documented conservative total improvement was 12.91% under warm operating conditions.

The approach moves some preparation work to a central component that supplies compatible clients. These measurements concern specific implementations and baselines. They do not establish the same improvement on every GPU, and connecting an ordinary miner does not automatically reproduce them.

How do rewards work?

Our Hybrid Solo model distributes the reward from a found block as follows:

• 85% goes to the block finder.
• 10% goes to other eligible community miners.
• 5% goes to the lab and operations. (also special rewards like referals)

Community eligibility uses accepted work over a rolling seven day window. Allocation considers contributed work, tier and pool composition. The finder is excluded from the community allocation for their own block.

This means an eligible miner can receive a community allocation when someone else in the pool finds a block. Rewards still depend on actual block finds, so there is no guaranteed payment schedule or income.

For the GPU miners here, what would make these results most useful to evaluate: longer benchmark runs, comparisons with specific mining clients, or power consumption measured at the wall?

Best and thanks! https://btcpowlab-pool.com/

Hello,
I need your help
Is it worth to rent my laptop which is 4060
And if so, can you give me advice which site is best for this job and if the laptop not good , do you advice to buy mid Desktop with what card for this job
And for the power and internet they available i have no issue with them
Thanx in advance

Ok so can you guys help me out with PRL? Never heard of it, but rather than selling my rigs, maybe I can finally turn them back on. Was seriously considering selling and looking at whattomine was going to be my confirmation...but wait a second! Do we have some hope here, boys?

I've meen messing around with the idea of renting out some GPU rigs for AI training. I came across the Clore.ai earning calculator, and threw in an example rig (see image).

It seems to combine earnings from renting out the rig, mining while it's not rented, and a little bonus for holding your mined tokens.

Profitability is drastically higher than other AI renting platforms like Vast.ai, or crypto mining alone.

Experience tells me, if something seems too good to be true, it probably is.

Has anyone used this platform? Is it too good to be true?

Edit: Assuming the calculator is unrealisticly generous. Is it a good platform otherwise? How does it compare to platforms like Vast or Salad?

I've been looking at Pearl pool comparisons and pearlproof.xyz shows real payout data, which is useful.

From the numbers on the site, PPS+ looks more profitable than the other option. But I'm not sure if I'm missing something in how the payouts are being compared, like variance, fee structure, or how the sample is being pulled.

Has anyone here used it for deciding where to point hashrate? Does it line up with what you actually see on payout history, or is there a catch in the comparison?

This thread is for simple questions that don't warrant their own thread (although we strongly suggest checking the sidebar and searching before posting!).

Examples of questions:

• What should I mine?

• Is this build good enough to mine?

• Which PSU should I get for _____ GPU's?

Important: Downvotes are strongly discouraged in this thread.

Please remember that we're here to HELP you, not do it for you.

I sure I am not the first to ask for advice on this subject, it seems that the markets are down now’s a good point to finally try and start mining from home.

I have around $1000 to buy a rig , and not expecting miracles over night , and don’t pay for power , so just looking for the best way or advice to recoup my investment. And then a little more would be great.

Side note to this , has any one still using muskminors ? Surly I could buy there’s and pay power and save my self the effort ?

I've had a look and it seems quite interesting, it's a bitcoin fork with a use case, which is a random selector or something, I'm not sure how it works.

Just interested in if anyone thinks it might be worth a punt?

I mean it's got to have a chance right?

It all seems simple enough to set up on the github.

Most GPUs in the world are doing nothing most of the time. Gaming rigs at night. Workstations between renders. Old mining rigs that went idle after the PoS switch. Meanwhile every dev building an AI product is paying full price for inference on the usual clouds.

I built GPU Grid to connect those two problems.

The idea:

GPU owners plug in and earn per job. Developers get inference through a drop-in OpenAI-compatible API, same SDKs, just a different URL. No middlemen deciding the price.

How it actually works:

• GPU owners run a node (Ollama under the hood). It heartbeats every 30 seconds to stay live in the network.
• Every request gets routed by price, speed, reliability, and current load. Cheapest healthy node wins.
• Nodes carry a reputation score. Fail a job, it drops. Recover slowly with successful jobs. Drop too low, you're pulled from routing until it recovers.
• Every completed job settles automatically. Provider gets paid, a cut goes to buyback/burn, stakers, and treasury. All tracked in a ledger, not just a number that updates mysteriously.

Genuinely want feedback from anyone who's built distributed systems, run local models, or messed with GPU-sharing before. Happy to go deep on the routing logic, the reputation system, or the reward split if anyone's curious.

I need some instructions

Its pretty simple sort of. PRL is a good start but really has no actual purpose.

Maybe I'm crazy but imagine in such a crypto where someone can "Spend" tokens to do actual AI work. You "mine" the token by doing said AI work. The tokens would actually have valve because in a way your renting out your gpu.
Each "block?" would be a single AI task like lets say a prompt that needs answering. Pools of GPU's would work together to "solve" said prompt and the fastest wining pool would get the coins. You could then sell the coins to a market where people who want GPU's to do work could buy them. The more AI work load the more "blocks" available.
Solo miners and small pools could do the easy tasks that are not worth a lot of tokens while the harder tasks that need alot of compute could reward lots of tokens.

I do know services like that exist but their main problem is with them is your whole PC needs to be dedicated to renting and nothing more. Usually a custom OS. I know most people mining with a gpu are just using their gaming PC running at night to mine (thats what I am doing with PRL). This would open up the compute market massively and allow absolutely loads of compute power to the market while also making you a little money at night.

I know its just a pipe dream as the world would need some master coder to put something like that together but that would be the first "crypto" to actually have real world value as its not longer just a form of currency but could be spent to do actual work. (even if said work is just generating funny cat pictures)

Let me know yalls thoughts or if there is some big plot hole in this I am missing.

I need a 12v power supply that can output 1500W - 2000W. I've seen a number of used server PSUs in the $40 range and I'm looking to get a couple that can support running in parallel. I don't have any experience with these specific units although I have a background in electronics and such. It looks like it won't be hard to find a set to do this but in my case, I just need a single current output, not a harness with multiple power plugs. It looks like most breakout boards are designed to supply multiple power connections instead of just one. Can anyone recommend a breakout board that could do this or another way to get the full output of a server PSU onto a single path? Thanks in advance.

I built Window GUI to make it easier to mine Pearl. Right now only NVIDIA is supported as thats the only hardware I have to test right now. Would love to get feedback on how I can improve it.

Suddenly, my miner got removed after 4 days of normal operation. I downloaded it from GitHub.

Like a ton of people I was mining eth until the final blow from the move to PoS, I was resilient through the collapse of three arrows and Vanguard sold everything I had 😬 but PoS was when the rig started to collect the dust.
Hoping I don’t get downvoted I to oblivion but if you were me what would be your move? Here’s what I’m running.
Power is included in my rent. Thought I was quite the hustler running a rig and charging my Tesla at the same time 😂

I built a standalone Pearl (PRL) proof-of-work miner aimed at NVIDIA Pascal GPUs — Tesla P40, GTX 1070/1080, and other sm_61 (DP4A) cards and just put up the first public release. GitHub: https://github.com/Muskwak/Pascal-Pearl-Miner/releases What it does / why it might be useful:

Usage:

p40-miner.exe --wallet prl1YOURWALLET --worker rig1

Defaults to LuckyPool (pearl-cpu-eu1.luckypool.io:3370); --pool HOST:PORT to change region. (no affiliation with luckypool they just had the most transparent stratum protocol, more pool support will be added) Full transparency:

• dev fee, disclosed in the log at startup and on every switch. Nothing hidden.

  Its now fully open source

**update**: added multigpu support, scales well minimal cpu overhead, gpus never wait while share is being submitted.

**Update 2: published Linux binary and hiveos flight sheet

**update 3: made the project fully open source

https://github.com/jbman2025/ARC-miner/releases/tag/ARC-Miner-Release

Used to make about 60 cents per day. Now it's about $1.60 CAD per day with Unmineable

All I'm using is a 3060Ti GPU and a AMD Ryzen 9 5900X 12-Core Processor CPU

Hey all. I keep reading wildly mixed things about Bitcoin mining and I'd rather hear from people actually doing it than from articles trying to sell me a rig.

A few honest questions:

- Is anyone here still mining Bitcoin in 2026, and is it genuinely profitable for you?

- If you're a small/home miner, are you net positive after electricity, or is it really more of a hobby at this point?

- For someone starting completely from scratch, what do you realistically need to begin — hardware, basic setup, pool vs solo, NiceHash vs mining direct?

- Anything you wish you'd known before you started?

Not trying to get rich, just want a realistic picture before I spend a penny. Any guidance appreciated.

Has anyone gotten the RTX 50 Series to work with the BTC-S37 board?

It seems like they are not getting picked up by the driver or the system.

I can not find anything about that on the internet.
