What's to be done

[kayabaNerve]

This is a scratch pad for work that needs to be done.

Networks:

• Finish/audit Monero (Monero Library Tracking Issue #102).
• Ethereum integration (including audit) (Ethereum Library Tracking Issue #110).

Processor:

• Economic policies regarding fees, insolvencies, and fee bumps (Support RBF #284, Dust handling #296).
• All its misc TODOs.
• Audit.

Tendermint/Tributary:

• Expand Tendemint evidence.
• Move Unsigned to Unordered, and Signed to Ordered.
• Signature aggregation for Tributary transactions.
• Audit.

Coordinator:

• Pruning of old tributaries.
• All of its misc TODOs.
• Audit.

Substrate:

• Liquidity airdrop pallet (Liquidity Airdrop Mechanics #354).
• Emissions.
• Weights/benchmarks.
• A variety of loose odds and ends in Substrate, documented in Substrate Considerations #379.

In general:

• A delay when having significant economic movement to further hedge against re-orgs (Increase confirmations needed for batch publication under large volume #281).
• Supply chain auditing (Audit the supply chain with cargo crev/vet #315, Supply chain integrity #317).
• Thoroughly test rotations.
• Thoroughly test DKG removals.
• Test validators with multiple keys.
• Test slash reports.

With regard to pruning, there's a TODO in the coordinator to spawn each tributary on their own volume to add a hard size cap to them (preventing a DoS on a tributary from crashing the entire system). Then pruning would simply be dropping their volume.

We likely want to spawn an independent DB, on the same volume, and then use the DB file size. If any DB grows too large, we'd cut off its P2P comms (effectively halting further growth). This prevents the DB from panicking, which will propagate to a service panic, while leaving pruning feasible.
