Continuous Intra Node Block Synchronization Flow

The source of truth for block synchronization in the node is BlockStorage. Some of the other services in the node need to be synchronized to the latest block as well in order to fulfill their functions.

Block synchronization intra node takes place by push from BlockStorage to each of the other services. Whenever a new block is validated and committed to BlockStorage, it will push the block to the other services. If the services are not in sync, it's the responsibility of BlockStorage to push all of the missing blocks to them until they are.

Participants in this flow

  • Synchronizer

    • BlockStorage

  • Receiving services

    • StateStorage
    • TransactionPool

Assumptions for successful flow

  • BlockStorage is synchronized to latest block.

Flow

  • BlockStorage gets a new block committed and pushes the block to the other services.

  • Receiving service asks to be synchronized if missing blocks (the pushed block isn't the next needed).

  • BlockStorage synchronizes the service as needed with all missing blocks.
