OP_CAT(BIP-420) Price

OP_CAT is an opcode designated as part of Bitcoin's scripting language, specifically Tapscript. Its primary function is to allow the concatenation of two stack values, a feature that was previously part of Bitcoin but retracted due to security concerns. This functionality is paramount for executing sophisticated scripts that can support enhanced operations within Bitcoin transactions.

By employing OP_CAT, developers can create and manage various advanced operations, such as constructing Merkle trees and evaluating hashed data structures. This is particularly important for maintaining data integrity and ensuring efficient transaction verification on the Bitcoin network. The reintroduction of this opcode is structured as a soft fork, which utilizes an existing opcode, OP_SUCCESS126, to facilitate the new concatenation functionality without disrupting the foundational aspects of the Bitcoin protocol.
