According to Cointelegraph, Tezos ecosystem developers have launched the quantum-resistant privacy payment prototype TzEL on the testnet. TzEL employs post-quantum cryptography and zk-STARK proofs to defend against “harvest now, decrypt later” attacks, safeguarding transaction data and encrypted payment metadata. The prototype also integrates Tezos’ data availability layer to handle the relatively large size of post-quantum proofs. According to the whitepaper, the quantum-resistant zk-STARK proofs used by TzEL are approximately 300 KB in size. TzEL is currently running on the Tezos testnet, and the Tezos ecosystem’s transition to post-quantum cryptography remains in its early stages.
According to an official announcement, Coinbase has suspended trading of 25 perpetual contracts, as previously announced. All outstanding positions in these contracts have been automatically settled at the final settlement price. The affected contracts include TRB, RARE, NEIRO, A, ME, XTZ, KMNO, RAY, STX, ENS, GMT, SNX, 1000FLOKI, 0G, ORDI, NIL, BIO, UMA, BEAM, INIT, SOMI, EGLD, CLANKER, SOPH, and BIGTIME. The final settlement price was calculated as the average index price over the 60 minutes preceding the suspension. Coinbase stated that this action aims to focus on products that consistently meet liquidity and market quality standards, and that it will accelerate the launch of new perpetual contracts by optimizing internal processes.
