Bitcoin Script is a stack-based, Turing-incomplete language for specifying transaction conditions. Advanced developers use it for multi-sig wallets, atomic swaps, and custom spending conditions. Layer 2 solutions (Lightning, Stacks) require Script expertise.

什麼是 Bitcoin Script Programming

Bitcoin Script is a low-level, stack-based programming language for specifying conditions under which Bitcoin UTXOs can be spent. It's Turing-incomplete by design, prioritizing security and simplicity over expressiveness. Advanced developers use Script for multi-signature schemes, time-locked transactions, atomic swaps, and privacy enhancements. Modern developments (SegWit, Taproot) expand Script capabilities while maintaining security properties. - Bitcoin-Native: Only way to interact directly with Bitcoin's transaction model

❓ 常見問題

What is UTXO and how does it differ from Ethereum's account model?
UTXO = Unspent Transaction Output, Bitcoin's model. Account model (Ethereum) simpler but less flexible for privacy and scalability.
What is the difference between SegWit and Taproot?
SegWit (2017) separated signatures from transactions. Taproot (2021) added Schnorr signatures, Merkle trees for privacy and efficiency.
Can I build Turing-complete smart contracts on Bitcoin?
No; Bitcoin Script is intentionally limited. Use Layer 2 (Lightning, Stacks) for complex logic.
What is a multi-signature (multisig) wallet and why use it?
Requires N of M signatures to spend. Ideal for corporate funds (3 of 5 executives), custody, key recovery.
How do atomic swaps work in Bitcoin Script?
Use time-locked HTLCs (Hash Time-Locked Contracts) to swap coins across chains safely without intermediaries.
What is the block size and how does it limit transactions?
1MB base block + 4MB witness data (SegWit). Limit is intentional (decentralization); drives Layer 2 adoption.
How do I analyze Bitcoin transactions to detect vulnerabilities?
Use blockchain analysis tools (Glassnode), Script debuggers, and domain expertise in economic incentives.
