getblockchaininfo
Returns an object containing various state info regarding blockchain processing.
Result:
{ (json object)
"chain" : "str", (string) current network name (main, test, regtest)

"headers" : n, (numeric) the current number of headers we have validated
"bestblockhash" : "str", (string) the hash of the currently best block
"difficulty" : n, (numeric) the current difficulty
"mediantime" : n, (numeric) median time for the current best block
"verificationprogress" : n, (numeric) estimate of verification progress [0..1]
"initialblockdownload" : true|false, (boolean) (debug information) estimate of whether this node is in Initial Block Download mode
"chainwork" : "hex", (string) total amount of work in active chain, in hexadecimal
"size_on_disk" : n, (numeric) the estimated size of the block and undo files on disk
"pruned" : true|false, (boolean) if the blocks are subject to pruning
"pruneheight" : n, (numeric) lowest-height complete block stored (only present if pruning is enabled)
"automatic_pruning" : true|false, (boolean) whether automatic pruning is enabled (only present if pruning is enabled)
"prune_target_size" : n, (numeric) the target size used by pruning (only present if automatic pruning is enabled)
"softforks" : { (json object) status of softforks
"xxxx" : { (json object) name of the softfork
"type" : "str", (string) one of "buried", "bip9"
"bip9" : { (json object) status of bip9 softforks (only for "bip9" type)
"status" : "str", (string) one of "defined", "started", "locked_in", "active", "failed"
"bit" : n, (numeric) the bit (0-28) in the block version field used to signal this softfork (only for "started" status)
"start_time" : xxx, (numeric) the minimum median time past of a block at which the bit gains its meaning
"timeout" : xxx, (numeric) the median time past of a block at which the deployment is considered failed if not yet locked in
"since" : n, (numeric) height of the first block to which the status applies
"statistics" : { (json object) numeric statistics about BIP9 signalling for a softfork (only for "started" status)
"period" : n, (numeric) the length in blocks of the BIP9 signalling period
"threshold" : n, (numeric) the number of blocks with the version bit set required to activate the feature
"elapsed" : n, (numeric) the number of blocks elapsed since the beginning of the current period
"count" : n, (numeric) the number of blocks with the version bit set in the current period
"possible" : true|false (boolean) returns false if there are not enough blocks left in this period to pass activation threshold
}
},
"height" : n, (numeric) height of the first block which the rules are or will be enforced (only for "buried" type, or "bip9" type with "active" status)
"active" : true|false (boolean) true if the rules are enforced for the mempool and the next block
},
...
},
"warnings" : "str" (string) any network and blockchain warnings
