What is the technical foundation of Bitcoin?

Bitcoin relies on blockchain technology to achieve peer-to-peer transactions through a decentralized network, without relying on central institutions (such as banks or governments). Its core algorithm verifies transactions through a large number of calculations and records them in a public ledger (blockchain), ensuring data is tamper-proof and secure.

Decentralization and Anonymity

The system is jointly maintained by global nodes, and transactions do not need to go through intermediaries such as banks. Users use private keys for digital signatures to achieve anonymity (addresses are not directly associated with identity). This characteristic gives it the ability to resist censorship and inflation.

Limited Supply and Scarcity

The total supply of Bitcoin is limited to 21 million coins, distributed through a "mining" mechanism, halving every four years (currently every 210,000 blocks). This scarcity is similar to gold, and some views regard it as "digital gold".
