The evolution of Central Bank Digital Currencies (CBDCs) is a complex journey from initial domestic experiments to the development of interoperable networks, akin to the evolution of the internet with the adoption of TCP/IP. Since 2014, countries like Uruguay and China have led early CBDC experiments, followed by cross-border initiatives aimed at addressing inefficiencies in international payments. These efforts highlight the challenges of achieving a universal blockchain platform due to varying technological preferences and jurisdictional requirements. The need for interoperability is critical, drawing parallels to the early internet's fragmented networks that eventually unified through a common protocol. The future of CBDCs and tokenized assets relies on developing a blockchain equivalent of TCP/IP, enabling secure, seamless transactions across diverse networks while maintaining compliance and privacy. This would facilitate the integration of traditional and decentralized finance, ensuring a cohesive, global financial ecosystem.
