According to Foresight News, Udi Wertheimer, the advocate of OP_CAT and co-founder of Taproot Wizards, has announced that OP_CAT, also known as BIP-42, is expected to launch on the Bitcoin testnet Signet next Tuesday, April 30. This will allow developers to build OP_CAT applications using CatVM and conduct real-time testing on the official test network.
Signet is the name of the Bitcoin test network designed for developers to test their software. It operates without miners and does not require proof of work, creating a block every 10 minutes on average.
