According to ChainCatcher, Ethereum founder Vitalik Buterin introduced a new image compression mode called "Token for Image Tokenizer" (TiTok) on the decentralized social media platform Farcaster, saying "320 bits is basically a hash value. Small enough for every user to be on the chain."

It is reported that TiTok was developed by ByteDance and researchers from the Technical University of Munich, and can compress images into 32 small data blocks (bits) without losing quality. According to the TiTok research paper, advanced artificial intelligence (AI) image compression enables TiTok to compress 256x256 pixel images into "32 discrete markers."
