Upcoming hard fork [view tags?]

[plowsof]

Hello, the upcoming Monero hard fork will be introducing view-tags

It would be nice to have this supported by the outputs function

[emesik]

I agree it would be great. Anyone willing to submit a PR?

I reached out to @j-berman who confirms that the json will appear as :

{ 
  "target": {
    "tagged_key": {
      "key": "ea3f...",
      "view_tag": "a1"
    }
  }
}

and offered his initial suggestion of how it may end up looking like - and because older transactions will not have view_tags, we must try: if one is set first. An implementation / work in progress of which can be found here

It would be also really nice to have some benchmarks done with a working implementation / simulated 'view_tag' block data, my guess is the scan time might be sped up more than 40% in python.

The PR i have made is to get the ball rolling. We can test it on testnet next month :) - i believe you are using the json-rpc wallet to construct a transaction? so i think no changes will be needed other than to support the view tags in finding outputs (i hope)

What is the height/date of scheduled release to the testnet?

So far, I rebased it and merged into the viewtags branch.

Thanks!

I have read that it is usually 1 month prior to the hard fork date , so we would expect it to be 16th June, but i will confirm those details for you.

Testnet fork height will be decided in the next dev meeting https://github.com/monero-project/meta/issues/700
