Perlin is a scalable directed acyclic graph (DAG) protocol that introduces a different technical angle to distributed ledgers. Perlin attempts to create a marketplace where users and suppliers can buy and sell distributed computing resources in an unstable environment.
Perlin innovatively uses the Avalanche protocol to develop distributed ledgers, leveraging the concept of metastability to provide high throughput and scalability. The Avalanche protocol is briefly introduced later to help you understand it quickly.
