# 14-4 Application Layer

Application Layer is for end-user DApps or mobile/web applications which use DonaBlock to integrate Commerce features on their services.

Commerce Service Providers, who provide end-user applications for customer transactions, are current e-Commerce service providers and, also, community/contents/social media app services wishing to implement influencer commerce.

Transactional and activity-related data from connected app services will transfer to Core Layer via Commerce Service Layer.
