Post Body

Hey everyone!

Welcome to Weekly Update 81. This week weā€™ll be focusing primarily on the Raiden involvement for the events of DappCon and ETHBerlin Zwei. The Raiden team has grown quite a bit since the beginning of the Weekly Update series so thereā€™s development to cover as well. Letā€™s dig straight in!

Raiden at Berlin Blockchain Week #2

In the previous Weekly Update (#80) we introduced the plans for the Raiden team attending Berlin Blockchain Week. Being close to one of the Raiden home grounds, quite a few from the team attended. At DappCon, Lefteris participated in the Panel: The road to scalability moderated by Martin from Gnosis. He later presented ā€œThe Road to Alderaanā€. Videos of DappCon will be uploaded to DappCon youtube channel, so weā€™ll be sure to share once thatā€™s released and do a TL;DW in the Weekly Update following.

Later that day, Dominik from the Raiden team participated in Layer 2 Meetup hosted by GEO Protocol and CoinFund, the video has been uploaded here. They go into the fundamental scalability challenges of Layer 1, the innovation potential and upgradability benefits of Layer 2 (reducing load and flexibility of having separate layers) whilst maintaining functionality to be able to verify on layer 1. As a TL;DW about Raiden specific content, the moderator asked about the journey and current state, the main points were that itā€™s not so hard to build a PoC relative to building that into a stable decentralized system when you so many moving parts. For example, accommodating Parity nodes and the Federation of matrix servers for Raidenā€™s communication layer. The technical journey focused on security, then stability, the stage weā€™re at currently is working on latency (namely PFS), privacy and steps towards usability (e.g. Raiden Wizard and MS). There was also some interesting discussion on channel balancing and challenge of getting users so Iā€™d recommend watching the panel or leave a comment if it interests you!

On the Friday at ETHBerlin Zwei, Franzi held a Raiden Workshop. Originally this wasnā€™t going to be recorded although we had a field-deployed Raideneer (u/surferfc) help out with a video upload. The purpose of the Workshop was to give an idea to hackers of how to start to build utilizing Raiden Network at the hackathon, beginning later that day. Raiden specific resources were collected and listed in the Awesome Raiden hackathon section. During the hackathon the Raiden team set up an application for anyone to try out at ethberlin.raiden.network with instructions on their Twitter. Later on, there was a short cover on the details of the Raiden bounties and Raiden Trust. If youā€™re curious of what the scene at ETHBerlin Zwei looked like the Golem twitter short a short clip. There was also a collection of Raiden swag & flags throughout the event.

On the topic of hackathons, the winners of Grow Ethereum were announced during the weekend to be Tip Raiden (@nanspro), a twitter bot for micro-payments using Raiden Network. And Raiden API SDK (@drdgvhbh), the typescript SDK for interacting with the Raiden API.

Development progress

Development progress continued forward even during the events. For notable Raiden GitHub development this week, there was a new light client v0.1 release which comes with payment functionality for light client users. Along with the release an npm package (raiden-ts) was created for easier development. On the client-side, there was the addition of flat mediation fee on a per token network basis. In the contracts, there were improvements needed with the PFS handling of larger networks which became apparent during testing so the devs came up with a solution for that. Testing of the services continues with each nightly version having scenarios run by the Scenario Player.

If you hadnā€™t noticed already, the WebUI includes a payment identifier that allows the payer to easily supply the payer with some information about each payment. An example of the utility of this was featured in the ETHBerlin Zwei interactive Bauhaus Raiden artwork.

Conclusion

To finish, itā€™s been a full-on week to cover and we managed to collect everything related to Raiden in this Weekly Update (I hope)! Even people not attending physically seem to have managed to collect a bit of a DappCon ETHBerlin Zwei hangover. So thatā€™s it for now, thanks for reading, please leave a comment if thereā€™s anything in this update or Raiden in general that you want to know more about.

Cheers!
