    4. Bitcoin is the OG of crypto. Satoshi Nakamoto launched it in 2009. However, Bitcoin didn’t have a smart contract option. Or did it? In 2010, Nakamoto disabled a function that indirectly allowed for smart contracts. That’s OP_CAT. The times they are a-changin, and we may see a comeback of this piece of script.

    What Is OP_CAT?

    Nakamoto created OP_CAT in 2009 when he created Bitcoin. However, in 2010, he disabled it. OP_CAT can bring smart contracts to Bitcoin. This would allow BTC holders to use it in BTCFi and make their BTC work for them. Currently, there’s a DeFi network on Bitcoin, but that’s all happening on layer 2 chains like Stacks or Rootstock. Putting the OP_CAT script back into action would allow for this to happen on the Bitcoin blockchain itself. It allows two pieces of data, like ‘A’ and ‘B’ to merge and become ‘AB’. Thus, making complex operations easier and simpler. This process is also known as concatenation. Now, the reason Nakamoto disabled OP_CAT is that it took too much memory to execute back in those days.

    What Is Taproot?

    Taproot is a soft fork upgrade for the Bitcoin blockchain. It dates from November 2021. Taproot increases scalability. It also improves efficiency and privacy. Taproot also opened the doors for smart contracts on Bitcoin. Now, with Tapscript, OP_CAT could start to play a role again.

    What Can OP_CAT Do?

    OP_CAT allows developers to build and manipulate larger integers straight within Bitcoin scripts. It also makes creating zero-knowledge apps easier. OP_CAT can allow Bitcoin to have smart contracts, leading to the rise of BitVM.

    Adding the OP_CAT script back into the Bitcoin script would add plenty of advantages. BTCFi would get a strong injection. OP_CAT would open plenty of new BTCFi opportunities. However, new developments in Bitcoin take time. It may not be until 2025 before we see OP_CAT being reactivated.
