[CHECKLIST] DKG Signing Manager v2

[drewstone]

Product Description

• The Signing manager currently suffers from a lot of redundancy. Every signing set signs the same message, and every signed message attempts to get submitted by each authority. We need to build a more parallelizable and fault-tolerant mechanism that helps us reduce our network throughput, while also increasing our signing throughput respectively.

Features List

• To be more parallelizable
• To reduce network throughput per unsigned proposal
• To increase signing throughput per batch of unsigned proposals

Task Checklist

• Leverage existing specs, and design + propose new Signing Manager mechanisms.
• Schedule time with key parties (Drew, Akilesh, Shady, Stanly, Thomas) and discuss.
• [TASK] Create rough diagrams that can be converted into well-designed visual descriptions of the Signing Manager. #530
• [TASK] Implement the new Signing Manager traits #531
• [TASK] Preprocess offline stages in bulk with an adaptable mechanism. #532
• [TASK] Parallelize signing operations for 1..n sized batches of unsigned proposals. #533
• [TASK] Implement resiliency logic in the event of failure at any step. #534
• [TASK] Track network topology and use to optimize signing set selection #536
• [TASK] Test using DKG harness and benchmark against previous signing mechanism. #535
