"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
