Origin and Development History
Background
Bitcoin was created by Satoshi Nakamoto in 2008 to solve the issues of centralized financial control and monetary debasement.
It was born during the global financial crisis, aiming to provide a secure, fast, and decentralized payment system that would change the status quo.
Bitcoin's launch brought new possibilities for individuals seeking financial sovereignty.
Important Milestones
- 2009: Bitcoin network launched, achieving the first decentralized peer-to-peer electronic cash system.
- 2017: Major upgrade (SegWit) introduced improved transaction capacity and laid the groundwork for Layer 2 solutions.
- 2021: Adopted by El Salvador as legal tender, pushing the price to break $60,000.
- 2024: Lightning Network expansion, with payment channels exceeding 1 million.
With support from its global 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) spread across the globe, 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 that records 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 to ensure scarcity.
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 capabilities and time-locked transactions.
Circulation Overview
As of December 15, 2025, Bitcoin's circulating supply is 19,962,275 coins, with a total supply of 19,962,334. The maximum supply is capped at 21,000,000 coins, adhering to a fixed deflationary model.
New coins enter the market through mining, which impacts its supply and demand dynamics.
Price Fluctuations
Bitcoin reached its all-time high of $126,080 on October 7, 2025, driven by continued institutional adoption and global economic uncertainty.
Its lowest price was $67.81, occurring on July 6, 2013, due to early market volatility and limited adoption.
These fluctuations reflect market sentiment, adoption trends, and external factors.
