TechTalks: Fermato — how it works

Looking for cloud storage? Fermato’s got you covered!

💡 This article is reprinted here from Iagon corporate blog.

It’s time for yet another part of the TechTalks series aimed at explaining the technical aspects of Iagon’s shared storage platform. In this article, we will elaborate on Fermato, a part of our high-level architecture. The purpose of this protocol component is to make it possible for storage consumers to purchase and manage storage space on the Iagon’s decentralized network.

In short, Fermato allows storage consumers to communicate with relevant smart contracts deployed on the Cardano blockchain. This way, they can subscribe for storage as a service on Iagon’s platform and manage all their subscriptions later on. In the future, we will also implement a feature responsible for access privileges settings.

The Mechanics

If we take a closer look at the architecture, it turns out that Fermato is basically a subscription manager acting as an intermediary between consumers and the marketplace.

To use Iagon’s storage service, a customer has to interact with our web interface. They define the parameters, i.e. how much space they need and for how long they want to use it. If necessary, specific storage locations can be chosen to comply with GDPR or other data privacy regulations.

The validator layer component checks the network, searching for storage nodes that fulfill the requirements. Once the nodes are selected, the network performance explorer we’ve described in the article about Adagio evaluates their performance records. Service rates are established based on the performance scores as well as on current supply and demand. Once the calculations are done, the rates are relayed to Fermato.
