Deep Dive
1. Purpose and value proposition
Bitcoin was designed as electronic cash that people can send to one another without a bank approving each transfer. Its network is open to anyone, though using it requires access to the internet and a wallet. The original design is described in the Bitcoin whitepaper.
2. Technology and architecture
Bitcoin runs on a public blockchain: a shared record of transactions maintained by computers around the world. Miners group transactions into blocks and use proof of work, a process requiring computing effort, to propose new blocks. Other network participants check that blocks follow Bitcoin’s rules. This design avoids relying on one organization to maintain the ledger. Bitcoin developer guide
3. Supply and governance
BTC is Bitcoin’s native currency. The protocol limits its total supply to 21 million BTC, and new coins enter circulation through mining rewards that decrease over time. No central authority sets the rules; changes to Bitcoin software depend on broad agreement among network participants. Bitcoin whitepaper
Conclusion
Bitcoin is both a digital currency and a decentralized network, combining direct transfers with a publicly verifiable ledger and a limited supply. How well can its base network serve everyday payments while preserving its security and decentralized structure?
