From proposal to network
Satoshi Nakamoto published the Bitcoin paper in 2008; the software network began in 2009. The proposal combined signatures, proof of work and a shared transaction history to address double spending without a central payment operator. Satoshi’s identity and educational background remain unverified.
Bitcoin did not invent every underlying technique. Its paper cites earlier work on timestamping and proof of work. The contribution was a working arrangement of these components and incentives.
What miners and nodes do
Miners compete to propose blocks using proof of work. Full nodes independently check whether blocks and transactions follow the rules; mining does not give permission to create arbitrary balances. A transaction’s confirmations describe the blocks built after its inclusion.
Bitcoin represents spendable value through transaction outputs. A payment can consume earlier outputs and create both a recipient output and change. Wallet software normally handles this accounting for the user.
How to read Bitcoin today
Separate the protocol, the software implementations, businesses using Bitcoin and the market price of BTC. An exchange adding a product is a business development, while a consensus-rule change is a different kind of event.
For current quotes use our market page; for current developments use the Bitcoin news archive. When evaluating a technical claim, ask whether it is a proposal, released software or an activated network change. A roadmap is not proof that a feature is already operating.
