Payment Protocol

Definition ∞ A payment protocol is a set of rules and standards that govern how transactions are processed and settled. In the context of digital assets, it defines the methods for transferring value between parties, often leveraging cryptography and distributed ledgers. These protocols ensure security, efficiency, and finality in payment operations. They are fundamental to the functioning of digital economies.
Context ∞ The current discourse on payment protocols often centers on their scalability, transaction fees, and the potential for broader adoption in mainstream commerce. Discussions frequently address the trade-offs between decentralization, speed, and cost. Future developments are expected to involve the refinement of existing protocols and the emergence of new solutions designed for micro-payments and cross-border transactions, potentially incorporating advanced cryptographic techniques.
