Cosmos hosted Sovereign Day Buenos Aires on November 18, bringing together financial and blockchain leaders to discuss how decentralized technology is reshaping global finance.
Buenos Aires, Argentina – Friday 21, 2025 – Sovereign Day Buenos Aires, hosted by Cosmos on November 18, welcomed financial institutions, policymakers, industry leaders, and blockchain industry leaders for a full day of programming. The event highlighted how blockchain is transforming global financial systems, featuring talks, live entertainment, and technical discussions. The event featured speakers from McKinsey & Company, Ondo Finance, the Argentinian Chamber of Fintech, LNET, Solana, Peersyst, and more.
To open the event, Maghnus Mareneck, Co-CEO of Cosmos Labs, delivered a keynote address, “Blockchain Technology Built to Rethink Finance” that outlined how the Cosmos technology stack now powers over 200 blockchains in production. He highlighted Cosmos’ expanding footprint across Latin America, where Cosmos Labs and partners are working directly with governments on digital currencies, national blockchain platforms, and cross-border interoperability pilots. This underscores Cosmos’ commitment to helping Latin America move on-chain.
In the panel “The On-Chain Debate: Diverse Visions for the Future of Open Finance”, Maghnus Mareneck, Co-CEO of Cosmos Labs, Antonio Neto, Head of Growth for LatAm at Solana, and Nick White, Chief Operating Officer at Celestia, highlighted how institutions are selecting the architecture that best fits their regulatory, technical, and operational priorities. The discussion pointed to a clear trend: global institutions increasingly demand customizable, compliance-ready blockchain infrastructure that offers end-to-end control. While private chains offer a stepping stone for experimentation, the panelists agreed that the future of open finance will be defined by interoperable networks capable of coordinating activity on a global scale.
Additional conversations examined the future of blockchain for institutions, addressing compliance considerations, the rise of real-world assets and stablecoins, and the importance of privacy and confidentiality. During the panel “How Banks & Enterprises Consume Web3 Services,” Nicolas Poggi, Chief Marketing Officer at Cosmos Labs, welcomed Tether’s Chief Expansion Manager, Andres Kim, and César Matienzo, former Systems Development Manager at Banco Galicia, to discuss the main frontiers that Latin American banking has to cross to move on-chain. On the matter, Poggi noted that, “Institutions are focused on the impact and the revenue or savings that a solution can create, only then they are concerned about the technology.”
Commenting on the success of the event, Mareneck said: “Sovereign Day Buenos Aires showcased just how quickly and decisively institutions are moving on-chain. Sovereign Day brought together the decision-makers shaping the next era of global finance, demonstrating how the Cosmos tech stack is enabling real-world adoption at national scale. We were excited to welcome Argentine institutions to Cosmos and had productive meetings with policymakers.”
Sovereign Day Buenos Aires was the second event of the Sovereign Series, a curated set of global gatherings aimed at exploring how blockchain solutions expand across markets.
