NullPool - Earn BTC Review: A Local secp256k1 Engine That Unseals Encrypted Mempool Payloads and Pays Per Payload

Most mining tools sell you the same thing: hashrate, a pool URL and a dashboard that slowly counts dust. NullPool points the engine somewhere else entirely. Instead of racing for block rewards, it works the mempool itself — encrypted pending payloads, taken apart locally with secp256k1 arithmetic and keccak-256 / sha-256 digests, then settled against the fee each payload already carries.

What the engine is actually doing

The math is the sales pitch, and it is real math. Elliptic-curve arithmetic runs across the full 2^256 space, with keccak-256 and sha-256 digests reproducing every address a payload can resolve to — the same computation a validator runs, executed on your own silicon instead of a rented cloud rig.

Payloads are unsealed as they hit the pool. Nonce ordering, signature recovery and the curve material behind each transaction are resolved byte by byte while the transaction is still pending, so the work happens inside the window where the fee is still attached to it.

That last part is the economics. Every pending payload carries its own attached fee, and resolution work settles against that fee, so BTC routes out the moment a payload is unsealed and scales with the traffic you process. There is no block lottery and no 10-minute wait for a share to be credited — the pool pays for the pool.

Inside the portal: five lanes and a live digest stream

The console is a single dark screen, and it tells you exactly what the machine is doing. Wallet connection is one click for EVM wallets, with Phantom wired in for Solana users, and the whole portal is gated until a wallet is connected — nothing runs unauthenticated.

The MEMPOOL SCAN arena is the centre of it: a FRONT counter, five scan lanes that report idle or working, and PAYLOADS and RESOLVED tallies that move as traffic is taken apart. Next to it, a KECCAK-256 STREAM panel prints the live digest stream in hex, so you can watch the hashing rather than trust a spinner.

The RUNTIME panel is the honest one. It reports the build (v1.0.0, stable), the engine (secp256k1 · keccak-256), a memory footprint of 12.8 MB and a scan throughput figure in units per second, which is the number to watch when you are tuning lanes. On a cold start it reads 0.00 u/s and an awaiting samples note until the first payloads land.

Then the OPERATOR ACCOUNT panel: an operator ID, the Start scanning button, a BTC profit meter sitting at 0.00000000 on a fresh session, plus routing rate, earned this operator and payloads resolved. Withdraw profit is marked premium only, which is the one gate worth knowing about before you start.

My first eleven days across five lanes

I took the seven-day trial, connected a wallet and started with three lanes to see what the traffic looked like. The first session ran 52 minutes and resolved six payloads for 0.00021 BTC — about $18 at the time — which is slow enough to be believable and fast enough to keep me watching.

By day four I had all five lanes open and the shape of the day mattered more than the settings. European morning and the US afternoon are busy; the quiet hours between roughly 02:00 and 06:00 UTC left the counters sitting still for long stretches, and no amount of lane tuning changed that. Eleven days in, the operator panel showed 0.0036 BTC earned, close to $313 at current prices, with the largest single payload routing 0.0009 BTC.

I upgraded to the three-month licence on day two, because the trial resolves but the withdrawal gate stays closed until you are on a paid plan. That is the honest trade: the trial proves the engine works, not that it pays out of the box.

What it costs

The trial is seven days and no payment is required — it starts the moment you take it. After that it is $49 for one month, $99 for three months (a $48 saving) or $199 for a year (a $389 saving over twelve monthly payments).

Payment runs in thirteen assets: BTC, ETH, SOL, ZEC, XMR, LTC, DOGE, DASH, XRP, TRX, SUI, BNB and USDT on ERC-20 or BEP-20. The engine itself targets encrypted mempool traffic on Bitcoin, Ethereum, Solana and Zcash, so paying in the coin you are already routing is the path of least friction.

Who this fits, and who it does not

If you want a set-and-forget cloud miner with a fixed daily number on the dashboard, this is the wrong tool. NullPool is an operator's console: you point it at a pool, choose lanes, and the return follows the traffic you actually process. Quiet mempool hours pay quiet numbers, and anyone promising a fixed daily BTC figure is selling something else.

If you already watch the mempool, understand what a nonce ordering and a signature recovery actually are, and want that work done locally on silicon you control, this is one of the few tools in the category that shows you its digest stream instead of a marketing graph.

The verdict

NullPool - Earn BTC is a v1.0.0 build that does one job on one screen, and it does it with real cryptography rather than a reward-share counter. Five lanes, a readable runtime panel, per-payload fee routing and a trial that lets you measure the traffic before you pay — that is a fairer deal than most of what passes for mining software in 2026.

Start with the free week, watch the resolved count instead of the profit meter for the first two days, and only then decide how many lanes your traffic justifies. The console is where the whole thing lives: open the NullPool portal and take the 7-day trial.
