     }, ...
  ],
  "bip9_softforks": {          (object) status of BIP9 softforks in progress
     "xxxx" : {                (string) name of the softfork
        "status": "xxxx",    (string) one of "defined", "started", "locked_in", "active", "failed"
        "bit": xx,             (numeric) the bit (0-28) in the block version field used to signal this softfork (only for "started" status)
        "startTime": xx,       (numeric) the minimum median time past of a block at which the bit gains its meaning
        "timeout": xx          (numeric) the median time past of a block at which the deployment is considered failed if not yet locked in
