This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Bitcoin was created by Satoshi Nakamoto in 2008, aiming to solve financial inequality and inefficiencies in traditional banking systems.

It was born during the global financial crisis, with the goal of providing a secure, fast, and decentralized payment system to change the status quo.

Bitcoin's launch brought new possibilities for individuals seeking financial autonomy.

Important Milestones

  • 2009: Mainnet launch, achieving the first decentralized peer-to-peer electronic cash system.
  • 2017: Major upgrade (SegWit) introduced improved transaction capacity and reduced fees.
  • 2021: Adopted by El Salvador as legal tender, pushing the price beyond $60,000.
  • 2024: Ecosystem explosion, with Lightning Network nodes surpassing 100,000.

With support from its community, Bitcoin continues to optimize its technology, security, and real-world applications.

How Does Bitcoin Work?

No Central Control

Bitcoin operates on a decentralized network of computers (nodes) worldwide, free from control by banks or governments.

These nodes collaborate to verify transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Core

Bitcoin's blockchain is a public, immutable digital ledger recording every transaction.

Transactions are grouped into blocks, linked through cryptographic hashes to form a secure chain.

Anyone can view the records, establishing trust without intermediaries.

Ensuring Fairness

Bitcoin uses Proof of Work (PoW) to validate transactions and prevent fraudulent behaviors like double-spending.

Miners maintain network security through computational power, and are rewarded with Bitcoin.

Its innovation includes a fixed supply cap and halving mechanism.

Secure Transactions

Bitcoin uses public-private key cryptography to protect transactions:

  • Private keys (like secret passwords) are used to sign transactions
  • Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, keeping transactions pseudonymous.

Additional security features include multi-signature wallets and time-locked transactions.

Bitcoin's Market Performance

Circulation Overview

As of November 14, 2025, Bitcoin's circulating supply is 19,948,537 coins, with a total supply of 19,948,537. The maximum supply is capped at 21,000,000 coins, reflecting its deflationary model.
New coins enter the market through mining, which impacts its supply and demand dynamics.

Price Fluctuations
