A new Bitcoin protocol named Tacit has emerged, focusing on enhancing privacy within the Bitcoin ecosystem. Tacit is categorized as a "meta-protocol," similar to BRC-20 and Runes, but distinguishes itself by running its indexing directly within users' browsers, eliminating reliance on centralized servers. This protocol obscures transaction amounts while maintaining transparency of transaction flows, akin to "ZEC on Bitcoin." Tacit employs cryptographic techniques like Pedersen commitments and Bulletproofs to hide transaction amounts, ensuring no tokens are created out of thin air. It also features a mixer for enhanced anonymity, embedding deposit proofs in Taproot transaction notes. However, it cannot mix native Bitcoin without first wrapping it. Since its launch on May 7, Tacit has rapidly developed features such as a marketplace and token swaps, with its native token $TAC reaching a market cap of $4 million. Developed by ross.wei, known for his work on Ethereum's ZAMM, Tacit aims to further enhance privacy features, including encapsulating native Bitcoin and silent receiving. Despite higher transaction costs, Tacit represents a significant innovation in the Bitcoin ecosystem, offering a new level of privacy for asset transactions.
