Zetina

The Zetina is a shared peer-to-peer network of Zero-Knowledge Provers. This network allows any party to join and utilize its services, operating with two main user roles:

1. Delegators: Users who present jobs to be executed on the network.
2. Executors: Users who execute the jobs submitted by Delegators.

Key Components

Peer-to-Peer Network of Hosts

This component ensures effective event-driven communication among hosts, facilitating the distribution of tasks and information across the network. Hosts stay updated and informed about new jobs through this network.

Registry Contract

This component manages the rewarding process for Executors. It verifies and awards Executors for correctly executing jobs and provides a secure platform for Delegators to deposit funds, which are then used to reward Executors.

Workflow Overview

1. Delegator Initiates Job:

   • The Delegator defines a job, consisting of a Job Header and a Job Body, and stores the Job Body in a Distributed Hash Table (DHT) within the p2p network. The Job Header is then sent using a Gossip-Sub message.

2. Executor Receives Job:

   • An Executor receives and verifies the Job Header. If valid, they retrieve the Job Body from the DHT, check the Delegator's account solvency, and execute the job.

3. Job Execution:

   • The Executor executes the job, producing a Job Witness containing the results and a zero-knowledge proof of correct execution.

4. Submission and Reward:

   • The Executor submits the Job Witness to the Registry. Upon verification of the Delegator's signature, the Registry sends the reward to the Executor.
