*** Note: there are plans to build and deploy a new version of state sync. As such, this version (v1) will be deprecated in the near future. See this issue for more information. ***
State synchronizer (State sync)
State sync is a component that helps Aptos nodes advance local blockchain ledger state by requesting and sharing transactions between peers. This helps nodes to synchronize with the most up-to-date state of the blockchain (e.g., if they fall behind or are freshly deployed).
Overview
Refer to the State Sync Specification for a high-level overview and description of State Sync.
Implementation details
This crate contains a state sync implementation as described in the specification mentioned above. The files of note in this crate are:
bootstrapper.rs
: the wrapper struct for creating state sync instances and local clients (client.rs
) to those instances.chunk_request.rs
&chunk_response.rs
: the definitions of the messages sent between Aptos nodes when making state sync requests and responses.coordinator.rs
: the primary state sync runtime that processes messages (e.g., from other Aptos nodes) and reacts appropriately.executor_proxy.rs
: the interface between the state sync coordinator and both storage and execution.request_manager.rs
: the actor that manages the network requests and responses between peers.
