Question about txInfoData

[L-as]

Are there any restrictions on what can be put in txInfoData? Can we put arbitrary extra data into it for use in scripts?

[JaredCorduan]

No, there is no way to put any extra/auxiliary data into the transaction context. Any data that you want to pass to a Plutus script should be passed via the redeemer.

[L-as]

Would you be open to removing this restriction?

[L-as]

This would be a possible alternative to adding something like `dataHash :: BuiltinData -> BuiltinByteString` to UPLC as a built-in.

@L-as in general, https://cardano.stackexchange.com is a better place to ask questions, the issues here are really for the ledger team to track work. And CIPs are the better place to propose new ideas: https://cips.cardano.org

I think it is more likely that we would add a builtin hash function for Plutus than that we would allow data in addition to the redeemer, just for the purposes of getting a hash. But this is just my first impression, take it with a grain of salt. :)

[L-as]

Thanks! Considering we seemingly already have the approval for adding `dataHash`, I'll just do that. Wasn't sure where to post this initially, didn't know there was an active stack exchange.

[JaredCorduan]

Np, glad you are interested in Plutus and how we can make it better!

[JaredCorduan]

@L-as you'll be happy to see this: cardano-foundation/CIPs#218 :)
