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.

מהי 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

❓ שאלות נפוצות

▶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.
