On July 1, OP_CAT supporter Udi Wertheimer, CEO of Taproot Wizards, said on the Xverse podcast that the probability of OP_CAT being activated is close to 100%. The OP_CAT feature, proposed by Ethan Heilman and Armin Sabouri last October, was recently launched on the Bitcoin testnet Signet and assigned a BIP-420 number, indicating that the ecosystem is seriously considering upgrading it. In addition, many crypto industry luminaries, including Solana Labs co-founder Anatoly Yakovenko, added "BIP-420" to the X platform's username to show support for this upgrade. Taproot Wizards launched the Quantum Cat Ordinals series in February to promote OP_CAT. In April, Taproot Wizards released a white paper outlining a framework for building applications using OP_CAT.
