What is a read only reference input

In the case where we are not using a reference input to reference another transaction input (at a Plutus script address), we can specify a read only reference input that is simply exposed in the Plutus script context.

how to use

  1. ./lockRferenceInput yourWalltName locks 25 Ada at contract
    • choose one utxo with only ada
  2. ./balance.sh yourWalletName shows utxos at given wallet name save the transaction hash of your token utxo
  3. ./unlockReferenceInput.sh yourWalletName will unlock all ada from contract utxo
    • first utxo only ada
    • second utxo the utxo with your token defined in the env.sh file used as reference utxo (not consumed)
    • third utxo just one from the contract
  4. use ./balance.sh again and compare the transaction hash, it hasn't changed
  5. other commands -./cbalance shows balance at contract

validator

Is valid if the reference input has the token, invalid if the token is a normal input.
