What does P2PKH stand for?

P2PKH stands for Pay to Public Key Hash, the most common transaction type.

Why is Bitcoin Script not Turing complete?

Bitcoin Script is deliberately limited to prevent infinite execution and ensure predictable transaction fees.

What is OP_RETURN used for?

OP_RETURN allows storing up to 80 bytes of data in the blockchain.

What does P2TR represent?

P2TR stands for Pay to Taproot, the latest transaction type enabling more privacy and efficiency.

What enables time-locked transactions in Bitcoin Script?

OP_CHECKLOCKTIMEVERIFY (CLTV) enables absolute time-locked transactions in Bitcoin.

Advanced Bitcoin Scripting

12 min readinteractiveIncludes quiz · 5 questions

Bitcoin has its own programming language called Script. It is intentionally limited — not Turing-complete like Ethereum's Solidity. This is a feature, not a bug. Fewer capabilities mean fewer attack vectors.

Dive deep into Bitcoin's scripting language and learn how complex transactions work.

Script Types:

•P2PKH: Pay to Public Key Hash (standard)
•P2SH: Pay to Script Hash (complex conditions)
•P2WPKH: Pay to Witness Public Key Hash (SegWit)
•P2WSH: Pay to Witness Script Hash
•P2TR: Pay to Taproot (latest)

Advanced Opcodes:

•OP_CHECKLOCKTIMEVERIFY: Time-locked transactions
•OP_CHECKSEQUENCEVERIFY: Relative time locks
•OP_RETURN: Data storage (80 bytes)
•OP_CHECKMULTISIG: Multi-signature verification

Key Takeaway

Bitcoin Script enables powerful features like multisig, timelocks, and hash locks while deliberately avoiding the complexity that has led to billions in smart contract exploits on other platforms.
