Applications and software technology as a whole architecturally exists in the form of a “Stack”; Layers of technology piled on top of one another.
The base layer technology is commonly referred to as Layer 1 & Layer 1 is a term used within the cryptocurrency and greater digital asset industry to refer to the ground floor level blockchain technology upon which further solutions are built. Typically it is the layer that offers consensus and security.
While there are no theoretic limitations as to how many layers can exist in a technology; when thinking in terms of blockchain technology there are generally addressable layers.
examples of Layer 1’s:
– Bitcoin – Ontology
– Ethereum – RavenCoin
– NEO – Ardor
