Tech Debt: Modularize Leap

[bhazzard]

Enable the construction of special purpose tools that perform a subset of a node's functions by splitting individual services provided by Leap into standalone libraries.

For each proposal, indicate:

• What do we want to split out?

• Why do we want to split it out?

• Use cases: 3 example use cases of the standalone library

  • Leap is the first
  • A contrived use case can be the 2nd
  • A use case w/ real world value should be the 3rd

• Dataflow

  • What data is explicitly provided to the library? What provides it?
  • What data does the library implicitly depend on? Where does it come from?
  • What data does the library explicitly provide? To what?
  • What data does the library passively emit? Where does it put it?

• What constraints might we impose on potential proposals. Why?

• What is a rough estimation of LOE to implement? More than a week? More than a Month? More than 3 months? More than 6 months? Etc

• Spike: Decoupled instrumentation feasibility

• Spike: Evaluate prerequisites for WASM Build Target

• Draft a proposal to split execution environment into a standalone C++ library AntelopeIO/leap#1030

• Draft a proposal for splitting block processing into a standalone C++ loop AntelopeIO/leap#1031

• Modularization of nodeos

Ideas for Product Features capitalizing on Modularized Leap

• Deepmind logger for nodeos
• Loki log aggregation tool for nodeos
