The Technology Behind Bitcoin: Blockchain
Bitcoin is one application of blockchain technology. To understand Bitcoin, let's first explain blockchain basics.
What is Blockchain?
Blockchain is a revolutionary data recording and transmission method that forms an immutable, cryptographically secured chain of information. It enables secure information sharing in decentralized networks by maintaining a transparent, permanent ledger of transactions stored in sequentially linked blocks.
Since blockchain data is encrypted and verified, no single party can alter records without network consensus. This tamper-proof nature makes blockchain a reliable, trustless system for tracking transactions like payments, orders, and accounts.
Key Blockchain Characteristics
Blockchain's core features are decentralization, transparency, and immutability. The decentralized network allows independent data validation across nodes without central control. Transparency enables public verification of all transactions, while cryptographic algorithms ensure data integrity once recorded.
Unlike centralized systems prone to trust issues, blockchain establishes consensus mechanisms through distributed networks. All transactions require participant consensus before updating the shared ledger in real-time, fundamentally solving traditional trust dilemmas.
Understanding Bitcoin
Bitcoin Basics
Bitcoin (BTC) is a decentralized cryptocurrency created in 2009 by Satoshi Nakamoto as a peer-to-peer electronic cash system. As the first and most established cryptocurrency, it operates without central authority using blockchain technology and cryptographic principles.
Bitcoin exists purely digitally through a process called mining rather than central issuance. Users can transfer value directly via P2P networks without intermediaries like banks. The system is designed to cap at 21 million BTC, with ~17 million currently circulating.
Why Does Bitcoin Have Value?
Bitcoin's value stems from:
- Scarcity: Hard-capped supply with lost coins reducing circulation
- Network Consensus: Collective agreement on its value, similar to gold or diamonds
After the 2008 financial crisis, Bitcoin emerged as an alternative to traditional finance, now becoming the most mature cryptocurrency.
How Bitcoin Works
Operational Principles
Decentralized P2P cryptocurrency system
Bitcoin operates like a democratic voting system where transactions require majority node approval. This design enables direct user transactions without intermediaries.
Transaction Process
Proof-of-Work consensus mechanism
Transactions are broadcast to the network where miners:
- Verify transactions via digital signatures
- Compete to solve complex mathematical problems
- Winner adds new transaction blocks to the blockchain
- Earns Bitcoin rewards through this "mining" process
Mining Rewards & Supply
Understanding the 4-year halving cycle
Miners receive BTC rewards for adding blocks:
- Initial reward: 50 BTC per block
- Halves every 210,000 blocks (~4 years)
- Total supply capped at 21 million BTC
- Final BTC expected by 2140
This controlled issuance mimics precious metal scarcity.
What Are Bitcoin Stocks?
Traditionally, Bitcoin stocks are publicly traded companies involved in:
- Cryptocurrency exchanges (e.g., Coinbase)
- Mining operations
- Blockchain technology development
- Crypto asset investments
- Related hardware/software services
Connection Between Bitcoin Stocks and AI Stocks
Many Taiwanese Bitcoin stocks overlap with AI concepts due to:
- Technical synergies: Shared reliance on high-performance computing (GPUs/ASICs)
- Data processing needs: Both fields require massive computational power
- Cross-applications: AI enhances blockchain through smart contracts and analytics
