Cluster of Workers

Cluster: Abstraction of Workers

Phala has many Workers but we do not expose them to developers directly. They are organized into Clusters and used by our developers.

• Contracts must be deployed to a Cluster, and a Cluster can hold multiple contracts

  • Contracts in different Clusters have no relationship, even if they share the same code

  • Contracts in one Cluster can call each other, and contracts in different Clusters need to call each other in an XCM-like way (BTW, the XCM support is WIP, so this should be supported soon)

• A Cluster is backed by one or more Workers

  • The Worker will run all the contracts in this Cluster

• Different access controls can be defined for different Clusters

  • like who can deploy how many contracts in this Cluster

Accordingly, we have a two-level contract tokenomics for this design.

• The L1 tokenomics define how you stake $PHA to rent Workers and form your Cluster

  • We will provide the public good Clusters, and people can stake $PHA to get the proportional computing power in our network

• The L2 tokenomics define how Cluster owners charge the contract deployers

  • We provide a template implementation (with Public and OnlyOwner rules) and will allow owners to implement their own logic with Phat Contract
