Weekly Dev Update #53

Hey Y’all,

Last week we finally released the Loki iOS Wallet! Things went pretty smoothly – we only found a few bugs which were quickly fixed. Thanks everyone who participated in the Testflight.

This week will be busy as we approach testnet release for Loki Core and Loki Messenger on June 26. Loki Messenger is in the final stages of testing in office for both iOS and desktop clients, and we’re finishing up some final changes in Loki Core to catch some bugs present in Checkpointing.

Loki Core

Fix export_key_image and key image generation failures (reported by Tokerato): https://github.com/loki-project/loki/pull/640
Add an RPC endpoint for requesting random Service Nodes: https://github.com/loki-project/loki/pull/638
Fix get_reserve_proofs (reported by Tokerato): https://github.com/loki-project/loki/pull/647
Drop connection when requesting duplicate transaction indexes: https://github.com/loki-project/loki/pull/637
Service Node Checkpointing work continues here in anticipation of testnet release: https://github.com/Doy-lee/loki/tree/ServiceNodeCheckpointing4

Loki Launcher

The Loki Launcher is a node js package that will allow for the independent management of all the components required to run a full Service Node. This includes managing Lokinet, lokid and the Loki Storage Server. When Loki Service Nodes begin to route data and store messages for Lokinet and Loki Messenger, the Loki Launcher will need to be run on every single Service Node.

Right now the Launcher is in a testing phase, so you should only use it on testnet and stagenet – though feedback/issues and pull requests would be greatly appreciated!

What’s going on this week with Loki Launcher:

Several team members reviewed the Launcher and we incorporated their feedback with testing and fixes in preparation for the first release.

What’s going on this week with Lokinet:

Lokinet reliability is still our focus and we’ve been progressing on improving our opt-in metric collection. We have replaced a core part of our software with a third party software library which eliminates the need to audit our custom implementation for bugs. And we’ve made other minor tweaks to the system to improve reliability.
