Atomic Settlement
Atomic settlement is the simultaneous, instantaneous exchange of a digital asset and its payment in a single blockchain transaction — eliminating the settlement risk inherent in traditional financial markets where security delivery and payment occur at different times.
Delivery vs Payment (DvP)
Delivery versus Payment is the fundamental settlement principle that transfer of a security must occur simultaneously with payment — eliminating principal risk — and blockchain-based atomic settlement represents the most complete technical implementation of DvP yet achieved.
