Decentralized Mithril Signature Diffusion - Prototype

[jpraynaud]

Why

The CIP-0137 describes a Decentralized Message Queue which allows the diffusion of Mithril signatures in a decentralized fashion. We want to implement a prototype of the proposed mini-protocols in the Mihtril nodes as well as the integration to a DMQ node.

What

Implement the diffusion of Mithril individual signatures from signers to aggregators with DMQ mini-protocols and support a ramp up phase for the DMQ network.

How

• Phase 1:
  • Implement a publisher abstraction for publication of signatures in signer #2427
  • Implement a signature processor for DMQ node in aggregator #2470
  • Implement delayer and retrier decorators of the signature publisher in signer #2461
  • Optimize run intervals handling in signer and aggregator state machines #2428
  • Record signatures origin in the signature processor of aggregator #2478
• Phase 2:
  • Implement the n2c Local Message Submission mini-protocol in Pallas #2515
  • Implement the n2c Local Message Notification mini-protocol in Pallas #2516
  • Implement a publisher with the n2c Local Message Submission mini-protocol with Pallas #2539
  • Implement a consumer with the n2c Local Message Notification mini-protocol with Pallas #2540
