OP_CAT's proposal to bring smart contracts to Bitcoin gets BIP 347

A serious attempt called OP_CAT to introduce smart contract functionality similar to Ethereum into Bitcoin has ultimately received "BIP number" 347. This is the first step in actually launching the long-proposed software upgrade. One of the co-authors of the proposal, Ethan Heilman of Armin Sabouri, said in an interview: "Obtaining a BIP number does not mean that the community has reached any consensus. It just makes discussions and software writing easier."
