Layers Infrastructure
A layer within a layer architecture is a type of software architecture that organizes functionality into multiple layers, each of which contains a set of well-defined services.
The services within each layer interact with the services within adjacent layers using a well-defined interface, such as an application programming interface (API), while hiding the complexity of the specific implementations within the layer. This type of architecture is designed to provide modularity, abstraction, and facilitate scalability, flexibility and component reuse.
What is a layer?
Profile Management:

This service would provide tools and mechanisms for managing and sharing user profiles and other information about the different stakeholders in the ecosystem. This service would enable users to create and maintain their own profiles, as well as to share information about their skills, interests, and experience with other stakeholders in the ecosystem.
Platform Layer
Wallet and Payment Management:

This service would provide tools and mechanisms for managing and tracking the flow of value within the ecosystem. This service would enable users to create and manage their own digital wallets, as well as to send and receive payments and other forms of value within the ecosystem.
Identity and Access Management:

This service would provide tools and mechanisms for managing and verifying the identities of different users and stakeholders in the ecosystem. This service would enable users to create and manage their own digital identities, as well as to authenticate and authorize their access to different IP assets and services in the ecosystem.
