AI agents are becoming the largest customer class in crypto. x402 has passed 100 million agentic transactions on Base, and the Linux Foundation's x402 Foundation now seats Visa, Mastercard, Stripe and AWS. Agents cannot be marketed to: they compare finality, fees and reliability, then execute in milliseconds. Winning this traffic requires sub-second finality, sub-cent fees, parallel execution and account abstraction at the protocol level.

    The Only Defence ESMA Accepts Is Technical

    This story was originally published on HackerNoon at: https://hackernoon.com/the-only-defence-esma-accepts-is-technical. ESMA says disclaimers cannot override facts. The one measure it recognises is technical, and the rest lands on brand architecture and product decisions. Check more stories related to web3 at: https://hackernoon.com/c/web3. You can also check exclusive content about #crypto, #mica, #regulation, #web3, #branding, #compliance, #fintech, #design, and more. This story was written by: @m1ke. Learn more about this writer by checking @m1ke's about page, and for more stories, please visit hackernoon.com. After the previous issue, the obvious question is what actually works. The usual answer is a banner saying the firm does not serve EU residents, and that is the one answer the ESMA guidelines rule out by name: the assessment is factual, and disclaimers cannot override facts to the contrary. The only measure ESMA puts forward is technical, either not onboarding new EU clients or a real geo-block. The rest lands on design: whether a client can tell which entity of a group they are dealing with, and whether the product records who took the initiative.

At launch it covers spot, futures and options trading, Bybit Earn, Copy Trading, Trading Bot, Loan, P2P, the Bybit Card, Spot X, the Rewards Hub and notification management, with customer support handled by the assistant working alongside human agents. Activating the feature creates a dedicated sub-account isolated from the user's main balance, with no API key or manual setup required. Bybit has also set out a roadmap to connect trading, earn, loans, card and support through a unified Open API. What is Bybit AI? A conversational assistant inside the Bybit app that interprets plain-language requests and carries out the corresponding action across trading, account management and customer support.

    Can chess moves be verified on-chain? — The answer is zero-knowledge proofs

    This story was originally published on HackerNoon at: https://hackernoon.com/can-chess-moves-be-verified-on-chain-the-answer-is-zero-knowledge-proofs. zkautochess, ZeroKing, and a zkEmail referee prove chess moves were legal on-chain. None of them can catch a player consulting Stockfish. Check more stories related to web3 at: https://hackernoon.com/c/web3. You can also check exclusive content about #zero-knowledge-proofs, #web3, #chess, #gaming, #decentralization, #cryptography, #future-of-nfts, #applied-cryptography, and more. This story was written by: @sriram-ramakrishnan. Learn more about this writer by checking @sriram-ramakrishnan's about page, and for more stories, please visit hackernoon.com. Zero-knowledge proofs let you prove a chess move was legal, or that a game ended in checkmate, without revealing the moves themselves. A small cluster of hackathon projects and research efforts — zkautochess, a Mina-based build called ZeroKing, a play-by-email "zkChess" referee, and general-purpose frameworks like ZkNoid — have actually built versions of this. It's a genuinely interesting corner of applied cryptography. It's also worth being honest about what it doesn't solve: proving circuits are expensive, chess has a large rule surface, and no proof can stop someone from quietly consulting an engine before typing a move in.
