The proposal details must be supplied via a JSON file. For values that contains
|
|
objects, only non-empty fields will be updated.
|
|
|
|
IMPORTANT: Currently parameter changes are evaluated but not validated, so it is
|
|
very important that any "value" change is valid (ie. correct type and within bounds)
|
|
for its respective parameter, eg. "MaxValidators" should be an integer and not a decimal.
|
|
|
|
Proper vetting of a parameter change proposal should prevent this from happening
|
|
(no deposits should occur during the governance process), but it should be noted
|
|
regardless.

$ %s tx gov submit-proposal param-change <path/to/proposal.json> --from=<key_or_address>
