What is Bitcoin (BTC)?

Deep Dive

1. Purpose & Value Proposition

Bitcoin was created to solve the reliance on trusted third parties in finance. Its 2008 whitepaper proposed a system for "online payments to be sent directly from one party to another without going through a financial institution." This design offers censorship resistance, lower transaction fees compared to traditional cross-border transfers, and gives users direct control over their assets.

2. Technology & Architecture

Bitcoin operates on a public, distributed ledger called a blockchain. Network participants called "miners" use specialized computers to solve complex cryptographic puzzles in a process called proof-of-work. This secures the network, validates transactions, and introduces new bitcoins at a predictable rate. The system is maintained by a decentralized network of nodes, ensuring no single entity controls it.

3. Tokenomics & Key Differentiator

A core, unchangeable rule is its absolute scarcity: only 21 million BTC will ever exist. New coin issuance is cut in half roughly every four years in an event called the "halving." This fixed, transparent monetary policy starkly contrasts with inflationary fiat currencies and is fundamental to its value proposition as a sovereign store of value.

Conclusion

Bitcoin is fundamentally a decentralized, cryptographically-secured network that provides a fixed-supply monetary asset and a permissionless payment system. As its ecosystem grows, how will its core functionality as a settlement layer evolve with new scaling technologies?
