//! Light client logic and implementation.
|
|
//!
|
|
//! A "light" client stores very little chain-related data locally
|
|
//! unlike a full node, which stores all blocks, headers, receipts, and more.
|
|
//!
|
|
//! This enables the client to have a much lower resource footprint in
|
|
//! exchange for the cost of having to ask the network for state data
|
|
//! while responding to queries. This makes a light client unsuitable for
|
|
//! low-latency applications, but perfectly suitable for simple everyday
|
|
//! use-cases like sending transactions from a personal account.
|
|
//!
|
|
//! The light client performs a header-only sync, doing verification and pruning
|
|
//! historical blocks. Upon pruning, batches of 2048 blocks have a number => hash
|
|
//! mapping sealed into "canonical hash tries" which can later be used to verify
|
|
//! historical block queries from peers.
