Several members of the Bitcoin community believe that the recent buzz about re-enabling Operation Concatenate (OP_CAT) could pose a significant security risk. OP_CAT was first introduced by Satoshi Nakamoto to allow two datasets to be combined into a single transaction script, but was banned in 2010 due to security risks. While reintroducing OP_CAT could facilitate asset tokenization, especially based on the success of Ordinals, rushing to implement it could jeopardize Bitcoin's security.
