Struct ckb_jsonrpc_types::ChainInfo

pub struct ChainInfo {
    pub chain: String,
    pub median_time: Timestamp,
    pub epoch: EpochNumberWithFraction,
    pub difficulty: U256,
    pub is_initial_block_download: bool,
    pub alerts: Vec<AlertMessage>,
}

Chain information.

Fields

chain: String

The network name.

Examples:

• “ckb” - Mirana the mainnet.
• “ckb_testnet” - Pudge 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.
