Objective

To sync to the blockchain, nodes need to be able to retrieve blocks from peers. These blocks must be advertised to peers to be validated and applied in chronological order against state data before participating in the network. In order to begin syncing, a sync server should be implemented to advertise blocks from peers for other peers to request.

Origin Document

V0 Client Side Challenge Mechanism

Goals

  • Build a sync server that advertises blocks from peers

Deliverable

  • Sync server that advertises its blocks and height for full sync (block 1)
  • Sync server that also provides requested blocks and height to peers

Non-goals / Non-deliverables

  • Implementation of block requests by the client
  • Implementation of block retrieval by the client

General issue deliverables

  • Update the appropriate CHANGELOG(s)
  • Update any relevant local/global README(s)
  • Update relevant source code tree explanations
  • Add or update any relevant or supporting mermaid diagrams

Testing Methodology

  • All tests: make test_all
  • LocalNet: verify a LocalNet is still functioning correctly by following the instructions at docs/development/README.md
