Bitcoin Mining, Explained for Beginners: What It Actually Does and Why It Matters
Mining isn’t a hobby for you. But it’s the engine that makes the rest of Bitcoin work. Five minutes here will save you a hundred misunderstandings later.
For years the honest answer to “can I mine Bitcoin at home?” has been no, not really. We said as much in our beginner’s mining guide: against industrial farms running hundreds of thousands of machines, a single home miner is buying a lottery ticket with a very expensive electric bill attached.
The BLAKE2b chain changes that math, at least for now. Because the chain switched to a mining algorithm that Bitcoin’s industrial ASICs cannot compute, its entire hash rate in early September 2026 was measured in tens of terahashes per second, less than one large mining container on the legacy network. A home miner with the right machine holds a genuinely meaningful share of the network. This guide explains what participating takes, in the order you would actually do it, with the risks stated up front rather than buried.
This is an educational walkthrough, not a recommendation to buy hardware. The chain is weeks old, has no established market price, and everything below is dated early September 2026. Verify current details on the project’s official documentation before spending money.
First, a 60-second recap of why this chain exists
In August 2026 a community of Bitcoin node operators activated BIP-110, a rule set restricting non-financial data in blocks. When the big mining pools refused to follow it, the community replaced the SHA-256d mining algorithm with BLAKE2b so that the pools’ machines could no longer produce blocks, and continued the chain without them. The full story is in our BIP-110 explainer. The consequence for miners is simple: it is a fresh field, and the tools are different.
Step 1: Understand what BLAKE2b hardware is
BLAKE2b is not a new algorithm. It was used for years by the Siacoin network, and manufacturers built ASICs for it. Those machines work on the BLAKE2b Bitcoin chain from its first block. Models the project has named include the Bitmain Antminer A3 and Goldshell’s SC-series units such as the SC5 Pro and SC-Lite. Goldshell also made small, quiet home units for this algorithm.
Because Siacoin mining had become marginal, this hardware sat on the secondhand market at a fraction of what a Bitcoin ASIC costs. Prices moved quickly once the fork was announced, so expect to shop around. When you look at a listing, confirm three things: the machine is a BLAKE2b (sometimes labeled “Sia” or “SC”) miner, its hash rate is quoted in gigahashes or terahashes per second, and its power draw is something your circuit can handle.
What about a regular computer? CPUs and graphics cards can technically compute BLAKE2b, and in the first days a few people mined with them. But they are thousands of times slower than an ASIC, and once even a modest number of ASICs are on the network, a GPU’s chance of finding a block drops to effectively zero. Treat CPU or GPU mining as a way to learn the software, not a way to earn coins.
Step 2: Run a full node (this is non-negotiable)
Mining on this chain requires two programs. The first is a full node: Bitcoin Knots in its BLAKE2b-enabled release. The release candidates were labeled RC5; look for the current stable version on the project site and download it only from there. Your node downloads and verifies the entire chain, the whole Bitcoin history plus the new blocks, and it is the only way to be certain you are mining valid blocks on the correct chain.
Practical requirements: a computer with well over 700 GB of free disk (an SSD makes a large difference), a reliable internet connection, and patience. The initial sync can take days on a slow connection. If you have never run a node before, our node guide covers the basics, and the process here is the same with a different software build.
Running your own node is also where the philosophy shows up in practice. On the legacy network, pool operators decide which transactions go into blocks. Here, your node builds the block template, which means you decide. For a chain founded on the idea that users should control what goes into blocks, that is the whole point.
Step 3: Set up the mining gateway
The second program connects your ASIC to your node. The project’s recommended tool is the DATUM Gateway, in the fork maintained by a group called CONVOY, which supports the new algorithm and the chain’s larger, version-2 block header. Your ASIC does not talk to the node directly; it talks to the gateway using the same stratum protocol it would use with any pool, and the gateway asks your node for block templates.
Configuration is a small text file: the address and port of your node, its RPC credentials, and the payout address where rewards should go. Generate that payout address from a wallet you control. A wallet on the node itself is the simplest option for a first setup.
Step 4: Point the ASIC at your gateway and watch
In the ASIC’s web control panel, where you would normally enter a pool URL, enter your gateway’s address and port instead. The machine will start submitting shares to your gateway exactly as it would to a pool. Then watch two things: the node’s log, which shows blocks arriving on the network, and the gateway dashboard, which shows your machine’s hash rate and any blocks it finds.
When your machine finds a block, the reward is 3.125 coins plus fees, paid to your address and spendable after 100 confirmations, the same maturity rule as Bitcoin. On a small network you may see it happen within days; on a growing one it may take much longer. That brings us to the part that determines whether any of this is worth doing.
Difficulty: the clock that is ticking
Bitcoin adjusts its mining difficulty every 2,016 blocks so that blocks arrive roughly every ten minutes; we explained the mechanism here. The BLAKE2b chain started far below Bitcoin’s difficulty so that a small group of miners could produce blocks at all, and it climbs as machines arrive. In the days after the chain restarted, hundreds of blocks were mined faster than the ten-minute target, which is exactly what a low difficulty and a rush of new hardware looks like.
The practical implication is that early participants earn a larger share of coins per unit of hardware than later ones. That is not an accident; it is the incentive the developers intended in order to bootstrap security. It also means that any calculation you do today about coins per week will be wrong in a month. Assume difficulty goes up, possibly steeply.
Solo versus pool on a small chain
On Bitcoin, solo mining is close to hopeless and pools are the only realistic option; we covered why here. On a chain whose entire hash rate is a few dozen terahashes, solo mining through your own node is realistic, and it is what the project’s developers encourage, because it keeps block-building in users’ hands. Pools for the BLAKE2b chain are beginning to appear. If you prefer steadier small payouts, favor pools that let your own node choose transactions, and keep an eye on whether any single pool is growing large enough to dominate a young network.
Electricity, noise, and the unglamorous parts
A Sia-era ASIC typically draws anywhere from a couple hundred watts for the small home units to a couple of kilowatts for the larger ones, and the larger ones are as loud as any other ASIC. Everything in our beginner mining guide about electricity rates, ventilation, and running the numbers applies. Do the arithmetic before you plug in: your rate per kilowatt-hour, the machine’s draw, and 24 hours a day. On the legacy network that arithmetic is what makes home mining unprofitable. Here the arithmetic on the other side of the ledger is unknown, which is the honest way to say what comes next.
What are the coins worth? The honest answer
As of early September 2026, no major exchange had listed the BLAKE2b coin and the large price trackers had not assigned it a ticker, though BIP110 has been proposed. Coins you mine are worth what another person will pay for them. One of the project’s developers, Chris Guida, has argued that the community should avoid KYC exchanges altogether and earn the coin by selling goods and services. That is an admirable vision, and it also means there is no easy way to convert rewards into dollars today. Anyone who tells you otherwise is selling something.
So who should mine? People who find the philosophy compelling and want to help secure a network they believe in. People who already own compatible hardware. Tinkerers who want the experience of running a node and finding a block with their own machine, which has been out of reach on Bitcoin for years. If your only goal is to turn electricity into dollars next month, this is not the project for you, and we would rather say so plainly.
Safety rules that apply no matter what
- Download software only from the project’s official sources. Forks attract fake wallets and fake miners that exist to steal seed phrases.
- Never enter a seed phrase that controls pre-fork coins into a new tool. Use a fresh wallet for mining rewards. Your pre-fork balance exists on both chains and is exposed to replay risk if moved carelessly.
- Treat confirmations as provisional. A small-hash-rate chain can be reorganized. Do not accept payment on the new chain as final the way you would on Bitcoin.
- Expect volatility in everything: difficulty, software versions, pool availability, and the rules themselves, which include temporary limits scheduled to expire in 2027.
Why we think this is worth writing about anyway
Every caveat above is real. And yet there is something remarkable in the fact that, in 2026, a person can buy a used machine, run a node in a spare room, and personally secure a Bitcoin chain that a group of users built to protect the original idea of small, verifiable, money-only blocks. That has not been possible on Bitcoin for more than ten years. Whether the BLAKE2b chain becomes a lasting network or stays a principled experiment, participating in it while one person can still matter is a rare opportunity, and it is why we added a full chapter on the fork to the September 2026 edition of our ebook.
