Impact analysis document

[ch1bo]

Why

With the CIP published (#333), the protocol design is much less of a moving target and much more suitable to investigate what would need to change for Leios?. Conducting an impact analysis is useful to identify which systems and components will need to be adapted for Leios, as well gauge the complexity of changes we expect at this time. Thoughts collected here will be refined in a more detailed node-level technical design (#542) and inform the implementation plan. Making the impact analysis public will also help the community better understand the consequences of the proposed consensus change.

What

• Create a public document that discusses the impact, requirements and expected changes to
  • The cardano-node as a system
  • The individual components and subsystems in the node
  • The ecosystem integrating with the node
    • (optional) contrasting the baseline vs. sharding

How

• Investigate and interview ecosystem for impact
• Impact analysis onto ecosystem #560
• Network component-level impact analysis
• Consensus component-level impact analysis of Linear Leios IntersectMBO/ouroboros-consensus#1463
• Ledger component-level impact analysis
• Crypto impact analysis #557
• Performance & Tracing impact analysis #561
• End-to-end testing impact
• (maybe) Create an updated c4 component diagram with architectural changes
• Collect everything into a markdown document on ouroboros-leios repository Expand scope of impact analysis document #555
