Commands for vrf evaluations

  mina.exe advanced vrf SUBCOMMAND

=== subcommands ===

  batch-check-witness     Check a batch of vrf evaluation witnesses read on
                          stdin. Outputs the verified vrf evaluations (or no vrf
                          output if the witness is invalid), and whether the vrf
                          output satisfies the threshold values if given. The
                          threshold should be included in the JSON for each vrf
                          as the 'vrfThreshold' field, of format
                          delegatedStake: 1000, totalStake: 1000000000. The
                          threshold is not checked against a ledger; this should
                          be done manually to confirm whether threshold_met in
                          the output corresponds to an actual won block.
  batch-generate-witness  Generate a batch of vrf evaluation witnesses from
                          "globalSlot": _, "epochSeed": _, "delegatorIndex": _
                          JSON message objects read on stdin
  generate-witness        Generate a vrf evaluation witness. This may be used to
                          calculate whether a given private key will win a given
                          slot (by checking threshold_met = true in the JSON
                          output), or to generate a witness that a 3rd party can
                          use to verify a vrf evaluation.
  help                    explain a given subcommand (perhaps recursively)
