Besu Fleet Mode Feature

[garyschulte]

Description

As a besu user, I want to enable a fleet of besu nodes that can follow a single parent besu instance to keep up with the chain head, without a consensus client.

Acceptance Criteria

• Implement trielog shipping mechanism from parent-to-child rather than a consensus client to follow the head
• Implement trielog query endpoints such that 'child' besu nodes can query for trielogs from 'parent' nodes
• implement light authentication, similar to execution api to enable authenticated/permissioned communication between parent and children fleet nodes
• Implement flat db sync and heal mechanism
• fleet mode trielog features should be developed using the besu plugin
• Enable besu to operate without a state trie, utilizing just flat databases
• Fleet mode should be compatible with the 'light mode' features defined in Bonsai & Blockchain Storage Improvements #5387

Additional Information (Add any of the following or anything else that may be relevant)

Flat db sync mechanism may not be required for V0, but discovery and benchmarking is part of this epic
