OP_CAT explained: Merkle trees in Bitcoin Script and trustless ZK rollups
Quote160 words
Explains OP_CAT (concatenation) as the opcode that enables Merkle tree creation and verification in Bitcoin Script, which is the core operation needed for STARK verification. Argues this opens the door to fully trust-minimized rollups on Bitcoin without overloading the chain.
Key claims
OP_CAT enables Merkle tree verification inside Bitcoin Script
Enables STARK verification and trustless ZK rollups on BTC
OP_CAT is a key opcode that will enable Bitcoin to handle more complex transactions without overloading the chain.
This will open the door for fully trust-minimized rollups on top of $BTC.

Bitcoin's scripting language allows for certain programmable logic to be included in transactions.
However, it is limited compared to other chains.
One of the challenges with adding this degree of complexity to Bitcoin transactions is that it potentially increases computational & storage requirements, which could subesquently lead to congestion and higher fees or slower transaction processing.
A well-designed opcode like OP_CAT enhances functionality without excessively burdening the network.
OP_CAT is short for "Operation Concatenate".
OP_CAT would allow concatenation of data within the Bitcoin script.
This uniquely enables creating and opening entries in Merkle trees within Bitcoin Script as the core operation enabling Merkle tree creation & verification is composed of concatenating two values and subsequently hashing them.
Imajin STARK verification in Bitcoin script.
