Hey everyone!

​

Welcome to Weekly Update 69. This update will be covering the latest mainnet release of the Raiden Network and the overall development progress. For anyone that happened to miss it, on the non-coding side of Raiden we also saw the ‘Smart contracts meet payment channels’ meetup in Frankfurt, hosted by AcceleratorFrankfurt, where Stefan from brainbot gave an introduction to payment channels. Let’s dive into update 69!

Raiden v0.100.3 - Rosemary

Last week, the Raiden team released the latest version of the Raiden client, v0.100.3 - Rosemary. It contains development progress of the last 3 months since the Pluto release.

In terms of features, Rosemary brings support for auxiliary services (monitoring and pathfinding) in development mode, compatibility with Görli Testnet and updated smart contracts. It also contains a lot of groundwork required for the complete integration of the auxiliary services which is still work in progress.

Additionally, the Rosemary release contains a considerable amount of bug fixes. The development team committed a significant amount of time towards fixing discovered bugs over the last 3 months which makes the Rosemary release much more stable compared to the previous release.

We invite everyone interested in the latest Raiden tech to install the Rosemary release and join the layer 2 community. If you have any technical questions you can reach the development team via the official gitter chat, while any potential issues can be reported on Raiden’s github.

Development progress

Parallel to preparing the codebase for the Rosemary release, the development team continued working on the open issues within the Ithaca milestone, new features related to the auxiliary services, the Light Client SDK, Raiden contracts and bug fixes.

Considerable progress towards implementing support for the withdrawal feature has been made during the last week. Once this feature is implemented, Raiden users will be able to withdraw funds from the channel without closing it. Furthermore, the development team started working on dropping support for the UDP transport layer. Continued progress on improving the test infrastructure (part of the Spring Cleaning) will make detection of bugs easier and accidental introduction of new ones less likely.

The part of the dev team that primarily focuses on the Raiden Services continued with features, such as:

• Implementing flexibility in mediation fees when a PFS is used, which will help to balance the network.
• Working on PFS routing feedback which will help allow users to get better routes over time.
• Improvements needed related to Raiden switching message implementation.

Conclusion

To wrap up this Weekly Update, the Rosemary release contains a number of features and benefits that help the Raiden project progress. If you’re interested in the summary of the Frankfurt meetup mentioned in the introduction, here’s a direct link. The next Raiden related events will be the ‘Understand & use Raiden’ workshop in London as well as a panel discussion on scalability at the Web3 stage of CogX two weeks from now.
