Struct Ext 

pub struct Ext(/* private fields */);

Extension for the group of transactions. It must be filled by the validator in Split or Merge types. Due to the check on create, extenstion cannot
be invalid. The valid extension must have: 1) unique coins, 2) the same
sender (validator), 3) correct coins ownership, 4) consistent transaction
order, types, values and count depending on the group type. Extension can be empty for Transfer type.
