# 3.2 Multi-chain nodes + Cloud computing clusters

PemChain Edge Cloud Computing Network is a complex network composed of multiple blockchain nodes and cloud computing clusters. The core of the network is the cloud computing cluster, which serves as a powerful center for computation and storage, providing necessary resources and services for the entire system.

* Pem Token

   PemChain utilizes PemToken to maintain the economic operation of the network.

* Pem Worker

Cloud service nodes, known as workers, use slot technology to register within PemChain.    Developers create customized cloud services such as CDN, cloud computing, AI rendering, etc.,       based on the application registry services provided by Pem workers.

* Pem Scheduling

Pem Scheduling acts as a dispatch service, scheduling workers on the chain to serve customers' API requests.

* Pem API

PemChain provides services externally in the form of APIs/Clients.
