Protocols running on this layer govern the key attributes of a payment transaction.
Examples of application layer protocols include Simple Payment Setup Protocol (SPSP) and Open Web Payment Scheme (OWPS).
A Complete Guide to Understanding This Blockchain Concept
SPSP is an Interledger protocol that allows secure payment across different ledgers by creating connectors between them.
OWPS is another scheme that allows consumer payments across different networks.
Once the protocols on this layer have run successfully, protocols from the transport layer will be invoked in order to start the payment process.
Why This Matters for Blockchain Technology
Understanding Application layer is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
