Swift announced that it will add a blockchain-based shared ledger to its technology infrastructure, a pivotal step for global finance that promises to make instant, always-on cross-border transactions possible at unprecedented scale. Swift already has kicked off work with a group of more than 30 financial institutions globally to design and build the ledger, focused on a first use case of real-time 24/7 cross-border payments and starting with a conceptual prototype by Consensys.
