The piece outlines the concept of "Banking 2.0," focusing on the evolution of banks towards on-chain systems. Traditional banking systems, which are often based on outdated core ledgers and localized currencies, will give way to a more integrated, digital approach. The article emphasizes that future banks will operate on blockchain technology, allowing for seamless management of multiple currencies and accounts. User experience is a key focus. Customers will be able to sign up and complete KYC (Know Your Customer) procedures to open accounts in different countries. When users fund their accounts with fiat currency, the funds will automatically convert to stablecoins. This setup enables the creation of multi-currency accounts, facilitating transactions across various local currencies while maintaining a clear on-chain ledger. The spending aspect is also addressed, highlighting how stablecoins can drive credit and debit card functionalities, including cashback rewards. Payments made with stablecoins will convert to fiat upon transaction initiation. For cross-border payments, stablecoins will exchange at interbank rates, ensuring real-time settlements around the clock. The integration of these features suggests a significant shift in how individuals and businesses will manage their finances globally.
