Weekly Dev Update #61

Hey Y’all, 

This week we continued work on some key areas in Loki Messenger, including adding chat channel support for Android and iOS, and starting work on support for Loki Messenger across multiple devices. We also released an update to the Loki Storage Server which allows for the measuring of additional statistics, so we can continue to monitor the network and the success of the switch from testnet to mainnet for Loki Messenger. 

Loki Core

There’ll be a point release to Loki Core this week with a number of bug fixes that should increase Service Node stability. This is not a mandatory upgrade but is recommended for those running Service Nodes. 

• Update Seed Nodes to remove inactive Seed Nodes (please contact the development team if you believe you can run a Seed Node):

   

  https://github.com/loki-project/loki/pull/791

• Service Node data optimisations and code cleanups/simplifications:

  https://github.com/loki-project/loki/pull/788

• Don’t relay Service Node votes or uptime proofs if node is syncing:

  https://github.com/loki-project/loki/pull/779

• Preserve pre 4.0.4 quorum states:

  https://github.com/loki-project/loki/pull/786

• Remove boundary HF12 uptime proof code:

  https://github.com/loki-project/loki/pull/785

• Make the rollback code for update_checkpoint be a soft fork compatible on the mainnet:

  https://github.com/loki-project/loki/pull/782

• Handle multi state changes in the pool:

  https://github.com/loki-project/loki/pull/781

• Remove NOTIFY_NEW_DEREGISTER_VOTE_CODE, inline the use of update_miner_block_template as it’s declared publicly but only used in cryptonote_core. Remove legacy P2P vote conversion methods:

  https://github.com/loki-project/loki/pull/778

• Fix checkpointing regression:

  https://github.com/loki-project/loki/pull/792

• Filter vote age before querying a Quorum (prevents vote spam):

  https://github.com/loki-project/loki/pull/777

Lokinet

If you’re on our Discord you can catch Jeff, the lead developer of LLARP, live streaming as he codes at https://www.twitch.tv/uguu25519. He typically streams on Tuesday mornings, 9am – 12pm Eastern (US) time.

What’s going on this week with Lokinet:
