Cardano Foundation CEO Frederik Gregaard has raised concerns about the accountability gap in artificial intelligence (AI) within the blockchain ecosystem. Gregaard emphasized the importance of determining responsibility when AI agents make consequential mistakes, questioning who authorized actions, what constraints were in place, and where accountability lies. As AI agents become more integrated into daily life, Gregaard warns that organizations must address these accountability issues to maintain trust and business viability. In related news, Cardano has expanded its reach in Switzerland, with ADA now accepted at 137 SPAR stores. This integration, facilitated by DFX.swiss's platform and the Open Crypto Pay standard, allows customers to use ADA directly from native wallets for payments, marking a significant step in Cardano's adoption.
