Bitcoin: How It Works, Mining, Price, and History
The bitcoin hub: how the network works, what mining actually does, where the price history sits, and how bitcoin compares with stablecoins for payments.
Bitcoin is a network that settles payments with no central operator. This hub covers how it works, how mining mints new coins and secures the ledger, how the supply schedule halves, and how bitcoin compares with stablecoins for everyday payments.
What this hub covers
Bitcoin is a payment network with no central operator. Payments are grouped into blocks. Blocks are chained by cryptography. Anyone can hold the full ledger and check it themselves. That is the whole machine. The bitcoin.org walkthrough says it in those terms, and this library follows [1].
This hub opens the bitcoin side of the library. The pages below cover the basics, the mining system, the price record, the conversion routes, and the comparison with stablecoins: what bitcoin is, the price record, conversion, mining, and stablecoins versus bitcoin. Each page names its sources. Each dates its figures. The rules are the same everywhere on this site.
The two fixed rules
Two protocol rules do the heavy lifting. The first caps the supply. No more than 21 million bitcoin will ever exist [2]. The second halves issuance on a schedule. New coins per block drop by half every 210,000 blocks, roughly every four years [2]. Everything about bitcoin’s monetary character follows from those two lines. The mining pages cover what they mean in practice, block by block.
How a payment settles
A bitcoin payment is signed, broadcast, and picked into a block. Miners assemble valid blocks and compete for the right to append one. The deeper a payment sits under later blocks, the harder it is to reverse. Confirmation is therefore probabilistic. The how-it-works record walks each step, and the library’s own bitcoin pages follow that walk [1]. Payments that need to move faster than that cadence have a second layer, the Lightning Network, with its own specifications and its own costs.
What mining is
Mining is two jobs at once. One job is assembling valid blocks. The other is competing for the right to append the next one. The winner collects newly issued coins plus the fees inside the block. That is the payment model that secures the network. It is not a metaphor, and it is not a savings product for readers. The mining family covers it in exactly those terms: the mining overview, the full explainer, the question of what it takes to mine now, and the hardware history.
Price and history, without predictions
The price page holds the market record. The history page holds the protocol’s own timeline. Neither page predicts anything. Readers weighing a position have the investing page, which holds what the documents say and issues no verdict. That is a standing rule on this site. It is also why those pages carry a date on every figure. A price without a date is noise; a dated price is a fact about a moment.
Bitcoin versus stablecoins
The comparison page sets bitcoin against dollar stablecoins on facts: settlement speed, fee behavior, volatility exposure, and what each is for. The short version is that they solve different problems. Bitcoin is a fixed-supply asset with a variable price. A stablecoin is a fixed-price claim with counterparty structure behind it. The stablecoins hub holds the other half of that story.
Conversion routes
Turning bitcoin into other money is its own subject, and the hub holds it as one. The conversion family covers the routes: exchange trades, currency pairs, and swap services. The exchange page holds how the venue model itself works, layer by layer. Each route has a different fee shape and a different counterparty. An exchange trade holds your funds during the trade. A swap service quotes a rate and executes against it. The conversion pages state the mechanics of each route and the fee shape each one publishes, without ranking the venues that offer them.
Holding it: the one irreversible mistake
The library’s basics family carries the custody pages, and they apply to bitcoin first. A private key controls the coins. A seed phrase backs the key up. Anyone who learns the phrase holds the coins. There is no operator to freeze, reverse, or recover. The seed phrase page treats that as a safety subject, not a footnote, because it is the one error in this system that no correction policy can repair.
Where this hub sits
The networks bitcoin runs beside sit under chains. Spending either asset is the spend hub’s subject. The basics and the glossary live at cryptocurrency. The rules that govern all of it start at regulation. Each hub links the others, so the trail never dead-ends.
