Understand Bitcoin mining.
Clear explanations of how mining works, how datacenters are built and which numbers matter, written for people who run, or want to understand, a mining facility.
Bitcoin mining basics
What mining is and how the protocol works.
What is Bitcoin mining?
Bitcoin mining explained simply: how miners secure the network, what hashing is, how blocks and rewards work, and what hardware and electricity are involved.
READ →SHA-256 in Bitcoin mining
SHA-256 is the hash function behind Bitcoin mining. Learn what a hash is, why it is hard to reverse and how miners use it to find blocks.
READ →Proof of work vs proof of stake
Proof of work secures Bitcoin with computing power, proof of stake secures other networks with locked coins. Compare security, energy and trade-offs.
READ →How transactions get confirmed
From the mempool to a confirmed block: how miners pick transactions, what confirmations mean and why six is a common standard.
READ →The difficulty adjustment
Every 2,016 blocks Bitcoin recalibrates mining difficulty so blocks keep arriving about every ten minutes. Learn how and why.
READ →Hashrate, difficulty and the halving
What hashrate means, how Bitcoin adjusts mining difficulty every 2,016 blocks and why the block reward halves every four years.
READ →The next Bitcoin halving
The Bitcoin halving cuts the block reward every 210,000 blocks. See when the next one is expected, what changes for miners and what does not.
READ →Block reward and transaction fees
A miner is paid the block subsidy plus transaction fees. Learn how each part works and why fees matter more over time.
READ →When the last bitcoin is mined
The last bitcoin is expected around 2140. Learn what happens to miners, fees and security after the subsidy ends.
READ →Cloud mining
Renting hashrate: what you get, what it costs and what to avoid.
What is Bitcoin cloud mining?
Bitcoin cloud mining explained: how renting hashrate works, what you pay for, what you receive, and the risks to know before you start.
READ →Top 10 checks before choosing a cloud mining provider
Ten things to verify before paying for cloud mining: terms, risk notice, price, cancellation, withdrawals, support and more. Use it on any provider, including us.
READ →Cloud mining vs buying a miner
Compare renting hashrate with buying and hosting an ASIC: upfront cost, electricity, noise, flexibility and risk. This is not a comparison of returns.
READ →Cloud mining contracts explained
Monthly, fixed-term and lifetime cloud mining contracts compared. Which clauses to read: fees, duration, withdrawals and cancellation.
READ →How to spot a cloud mining scam
Red flags in cloud mining: guaranteed returns, no terms, no withdrawals, anonymous teams. A checklist to protect yourself.
READ →What is a terahash?
TH/s, PH/s and EH/s explained: how hashrate is measured, how it relates to rewards and why efficiency in J/TH matters.
READ →Hashprice explained
Hashprice is the expected revenue per unit of hashrate per day. Learn how it is computed and how to compare it with your costs.
READ →Is Bitcoin mining legal?
Bitcoin mining is legal in many countries and restricted in others. A general overview and why you should check local rules.
READ →Hardware and infrastructure
Machines, cooling, power and pools.
ASIC vs GPU mining
ASIC and GPU miners compared: specialised versus general-purpose hardware, efficiency, flexibility, cost and which coins each one can mine.
READ →History of mining hardware
Bitcoin mining moved from CPUs to GPUs, FPGAs and finally ASICs. See why each step happened and what it means today.
READ →Mining efficiency and J/TH
J/TH explained: how joules per terahash measure ASIC efficiency, how to compute power draw from hashrate and why lower is better.
READ →Immersion cooling for mining
How immersion cooling works in Bitcoin mining: dielectric fluids, single-phase and two-phase systems, benefits for overclocking and heat reuse.
READ →PUE: Power Usage Effectiveness
PUE explained: the ratio between total facility energy and IT equipment energy, what good values look like and how cooling affects it.
READ →How a Bitcoin mining datacenter works
Inside a Bitcoin mining facility: racks of ASICs, power distribution, cooling loops, networking and monitoring, and how operators keep uptime and efficiency high.
READ →How our mining infrastructure works
OnlineCryptoMining runs Bitcoin mining on real infrastructure you manage online. Learn how it works and what the live figures mean.
READ →Mining pools and Stratum
How Bitcoin mining pools work: shares, payout schemes such as PPS and PPLNS, and the Stratum protocol miners use to talk to the pool.
READ →Solo mining vs pool mining
Solo mining pays rarely but in full, pool mining pays small amounts regularly. Compare variance, fees and what suits a small miner.
READ →Pool payout methods
PPS, FPPS, PPLNS and PROP explained. How each method splits rewards, who carries the risk and how fees differ.
READ →Costs, wallets and withdrawals
Electricity, fees and keeping your bitcoin safe.
Electricity costs in Bitcoin mining
Why power price is the main cost of Bitcoin mining, how to compute the cost per BTC, and why location and efficiency matter.
READ →Bitcoin mining and energy
Why Bitcoin mining uses electricity, how efficiency is measured and why miners look for cheap, stable power.
READ →Withdrawals and network fees
How Bitcoin withdrawals work: addresses, confirmations, network fees and why identity checks may apply.
READ →Wallet basics for miners
