Expand description
The overall chain synchronization state of this local node.
Fields
ibd: bool
Whether the local node is in IBD, Initial Block Download.
When a node starts and its chain tip timestamp is far behind the wall clock, it will enter the IBD until it catches up the synchronization.
During IBD, the local node only synchronizes the chain with one selected remote node and stops responding to most P2P requests.
best_known_block_number: BlockNumber
This is the best known block number observed by the local node from the P2P network.
The best here means that the block leads a chain which has the best known accumulated difficulty.
This can be used to estimate the synchronization progress. If this RPC returns B, and the
RPC get_tip_block_number
returns T, the node has already synchronized T/B blocks.
best_known_block_timestamp: Timestamp
This is timestamp of the same block described in best_known_block_number
.
orphan_blocks_count: Uint64
Count of orphan blocks the local node has downloaded.
The local node downloads multiple blocks simultaneously but blocks must be connected consecutively. If a descendant is downloaded before its ancestors, it becomes an orphan block.
If this number is too high, it indicates that block download has stuck at some block.
inflight_blocks_count: Uint64
Count of downloading blocks.
fast_time: Uint64
The download scheduler’s time analysis data, the fast is the 1/3 of the cut-off point, unit ms
normal_time: Uint64
The download scheduler’s time analysis data, the normal is the 4/5 of the cut-off point, unit ms
low_time: Uint64
The download scheduler’s time analysis data, the low is the 9/10 of the cut-off point, unit ms
