CAT Protocol

What's OP_CAT and why do I care about it? Bitcoin's computer is a bit like a clunky scientific calculator, the kind used in high school. Each button is called an "op_code." And from time to time, the Bitcoin community may agree on adding a new button. OP_CAT is one such…

✅ Example Without OP_CAT (Current Meta Protocol Situation) Let’s say Alice wants to lend 1 BTC to Bob using a DeFi app built on an overlay protocol like Stacks or RGB. Here’s what happens: Alice sends 1 BTC to a custodian (like a smart contract on Stacks). The smart contract…

打假聪网(Sat20)！！！ 比特币的底层架构决定了其网络难以实现复杂智能合约，无法支持类似以太坊虚拟机（EVM）的功能。多年来，众多技术大咖屡次尝试在比特币上实现智能合约，但均未成功，这也是 Vitalik Buterin 开发以太坊的主要原因。 比特币网络发币的早期尝试是染色币（最多时400多中），通过…

NEW GWART POD: OP_Cat, Bitcoin MEV, and Scaling Bitcoin With Post Capone Welcome back to The Gwart Show! Today, Bitcoiner Post Capone joins us to talk about the risks of OP_CAT activation, MEV extraction concerns on Bitcoin, how increased expressivity could lead to mining…

BitcoinFi isn’t waiting for OPCAT. @Starknet, @Stacks, BitVM — builders are here. Are you ready?

Imagine how high it'll go if you bundle in CAT, @theinstagibbs 🙃

BREAKING: Director of Research @ Blockstream and Co-inventor of Taproot says path for OP_CAT is finally clear - ETHAN AND ARMIN FINALLY DID IT - UNBELIEVABLY SIMPLE ”You look at CAT and there’s nothing to bikeshed on - almost no technical risk - everyone likes CAT”

I really hope Bitcoin adopts a soft fork of CTV+CSFS, because lots of devs I respect support it. I also hope that down the line CAT is adopted, to unleash STARK verification for Starknet and anyone else scaling bitcoin with proofs.

I'm enjoying talks at BTC Prague Dev/Hack day. Here's Tobias from @rhinofi surveying Bitcoin L2s

It would be sad if Bitcoin ossified into an asset held only by select few rich people, while all the rest will only access it via ETFs by tradfi. To prevent this, we need to allow Bitcoin to scale, via OP_CAT or other soft forks

We have been trying to build DeFi on BTC for nearly two decades... We are not at an early stage... To the contrary, the limitations of BTC are well known now Without changes to Core, like OP_CAT, DeFi remains impossible The political analysis is obvious; OP_CAT is not passing!

TLDR on BitVM trust assumptions + why BitVM isn’t the end game:
