This week in Tari
Version changes
We have introduced a few changes to how we version code releases to make it easier to identify which codebases are running on which Tari network.
- Versions with a suffix of
rcare running on nextnet, - Versions with a suffix of
preare running on testnet (this is still currently Esmeralda).
We covered the reasoning in a recent developer update, and subsequent to that, we wrote a detailed guide on the versioning.
Testnet chain reset
With all of the breaking changes that where done recently it was decided to reset the Esmeralda testnet chain back to 0 again.
Balanced Merkle Trees
For the Dan layer, we have changed over from using Merkle Mountain Ranges to just using Balanced Merkle Trees as this should provide much better performance in terms of speed and size, see the PR #5189 for more details and actual numbers.
Wallet encryption
There have been multiple updates and changes to how the wallet handles its own encryption. Most of these have been breaking changes and require the wallet to run recovery. But in the end, we are trying to ensure that using the wallet the data is properly and securely encrypted.
DAN improvements
On the Digital Assets Network layer, more PRs relating to confidential assets have been merged, and we are getting closer to MVP for confidential assets. We have also merged a few PRs to start with claiming funds one the DAN. This will allow users to claim Tari burned on the main layer as funds to be used in the DAN layer.
And finally, here is the complete list of features and fixes we’ve made from version 0.46.0 to 0.49.0-pre.1
