  • requestType is getBlockchainStatus


  • currentMinRollbackHeight (N) is the current minimum rollback height
  • numberOfBlocks (N) is the number of blocks in the blockchain (height + 1)
  • isTestnet (B) is true if the node is connected to testnet, false otherwise
  • includeExpiredPrunable (B) is the value of the xin.includeExpiredPrunable property
  • requestProcessingTime (N) is the API request processing time (in millisec)
  • version (S) is the application version
  • maxRollback (N) is the value of the xin.maxRollback property
  • lastBlock (S) is the last block ID on the blockchain
