The hottest narrative in the market right now is "privacy". Privacy coins like L1 (Zcash, Monero..) that hide transactions to obscure the sender/receiver, or mixers utilizing ZK (Tornado Cash, Railgun..) have been heavily suppressed due to regulations. In 2023, many privacy coins that were already listed on most CEXs were completely delisted. However, as movements advocating for the legitimacy of privacy on the blockchain centered around Ethereum are growing, the market is shifting in an unfavorable direction for privacy. The Ethereum Foundation even released the "Ethereum Privacy Manifesto" through its official blog. Despite regulatory suppression, Ethereum has consistently asserted the importance of privacy. (In fact, Vitalik is a regular user of Railgun and even donated 50 ETH to help the Tornado Cash developers with their lawsuit.) The most critical technology for privacy on the blockchain is ZK. Most privacy projects, such as Zcash, Railgun, and Tornado Cash, are implemented using ZK technology. As the importance of privacy increases, the necessity for ZK proof projects like @brevis_zk will also grow. Additionally, to prevent privacy leakage from the Prover generating ZK proofs, TEE will once again come into focus. Ethereum is for Privacy.
