Expand description
Chain information.
Fields
chain: String
The network name.
Examples:
- “ckb” - Lina the mainnet.
- “ckb_testnet” - Aggron the testnet.
median_time: Timestamp
The median time of the last 37 blocks, including the tip block.
epoch: EpochNumberWithFraction
The epoch information of tip block in the chain.
difficulty: U256
Current difficulty.
Decoded from the epoch compact_target
.
is_initial_block_download: 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 the most P2P requests.
alerts: Vec<AlertMessage>
Active alerts stored in the local node.
