# Public Notes on ZSA Discussions

## 2/12/2021 - Arborist call

- how many assets can you fit in a single transaction / circuit
- probably around 10 could work
- there is also transaction size limit on the number of actions
- 2109 was the limit for Sapling outputs
- https://zips.z.cash/protocol/protocol.pdf#orchardbalance

- for issuance / minting:
- how much state does the full node have to maintain? Would add
- registry list as transparent UTXOs from TZE outputs
- or state from a new transaction type / version
- this yields a trade-off: how extensible are TZEs vs how much state must be maintained with new tx types?
- Do we want to (eventually) allow minting privately?
- In any case, if do TZE-based issuance, then think about extensibility: what if we want to change to registry-based in the future?

- backwards compatibility
- in order to use the Orchard-ZEC in the new ZSA-Orchard one can have either the type be all "0" or have a deafault note slot that does not have a type.
- Most likely will not need a turnstile method
