So, how receiving accounts are generated in a higher deterministic manner or randomly and if tags are known or private is still being discussed and explored.
Most of the tests have fit. Just hashing a file with certain algos like SHA1 makes for short hashes, but others can make very long ones. But currently we are using signatures for the final message on chain, so it should be okay. But yes, it would be nice if we had more message space. I’m sure we could find a way to use it for something nice.
What also would be really neat to me is if I was able to send two messages to two accounts in the same transaction. I’ve been playing around with that. (Different use cases for this)
Rev also has a system mostly ready that can chain transactions together, but that is more of a plan B.
Gimre is the core dev in charge of Lightwallet. QM is designing a fork that will have Apostille notarization in it. We are just going at it cowboy style. I also hope that this can be forked into the main Lightwallet, or just become the main lightwallet but ultimately Gimre will have to consider that and how it fits into the greater plans.
