New multiaddress format, Substrate on nix, open source Fearless wallet by Soramitsu, W3F's free and open source identity registrar, a ton of events, and more!

Thank you for taking the Dot Leap!

We cover Polkadot, Kusama, Substrate, and all related Web 3.0 projects! Want your content featured? Tweet at the author!

Polkadot (v0.8.26.)


Polkadot Governance

As Council member, I wrote up my activity report for transparency here.

Kusama (v0.8.26.)

⚠ Updates

  • A user suggested the redenomination of KSM in a 1:100 ratio just like what happened with Polkadot. This is going to be a tricky sell given that Kusama is its own network and has been in production for a while, so this would cause some confusion across the ecosystem.

    It’s even trickier because the proposal is non-binding - it’s just a system remark which doesn’t really do anything per se, only measures KSM holder sentiment towards the idea, so the maintainers would be the ones who would have to implement this. We’ll see how it plays out. As a councilor, I am against the idea purely due to the confusion it would cause.

🏛 Kusama Governance

As Council member, I publish all my decisions in regular posts whenever I act in this official capacity. Here’s the post from October 14th, one from October 20th, and another from October 27th.

  • I turned Treasury proposal 51 into Motion 226 to support further development of the NFC wallet project.

  • Motion 227 created the first Kusama bounty - a request for creating a Bounty UI for Kusama. I voted Aye to support the creation of the bounty.

  • Motion 228 proposed Jaco, the author of Polkadot JS Apps as the curator for a bounty focusing on the development of a Bounty UI addon for Polkadot JS Apps (see above). I agree with the general consensus that Jaco is the most qualified to curate this work, so I voted Aye. The motion ultimately passed but failed to execute because the bounty was not yet funded. It has been subsequently passed as Motion 231.

  • Motion 229 is a replacement for a motion from a while back which sought to increase the number of validators by 1 every era until 400 new validators have been added in (only this referendum caps this at 100 new validators). The previous referendum passed, but due to an invalid parameter in the scheduler's command wasn't executable, so it ultimately failed. I voted against the previous referendum, something I explained in my report from October 8th. The reason why this is a motion and not a public referendum again is because unclear instructions caused the previous referendum's failure, even though the referendum itself passed. The motion is a correction of that "bug". As such, despite me disagreeing with the ultimate aim of the referendum that will be the result of this motion, I must vote Aye because the referendum already passed previously.

Ethereum Compatibility

As Moonbeam and Parity’s Frontier mature, I believe it’s worth having a separate section discussing Ethereum compatibility with Substrate and Polkadot in general. The potential for collaboration between the two ecosystems is immense.

🛠 Tools

👨‍🎓 Education

  • Bill Laboon gave an overview of proof of stake and engaged in a roundtable discussion with reps from Ethereum 2.0, Tezos, Cardano and Concordeum at CV Labs' "2020 - The Year of Proof of Stake" discussion. 

  • All Sub0 recordings are available on Crowdcast.

  • Bruno Škvorc presented Substrate and Polkadot at a conference in Osijek, Croatia. Video of Day 1, video of Day 2. The content is in Croatian, share with your Croatian friends!

🤝 Ecosystem

📅 Upcoming Events and Webinars

  • Oct 28th:, Bruno Škvorc will show you how to build custom UIs for Substrate.

  • Nov 2nd:, Bruno Škvorc will show you how to query past data of a Substrate chain.

👷‍♂️ Jobs

Don’t forget to vote!

Your vote only costs a TX fee (a few cents) but it can change the protocol (both Kusama and Polkadot - depending where you vote for me!) for ever - good governance is responsible governance! Click the banner to learn about my candidacy!

That's it for this week - I hope this was as useful for you to read as it was for me to write! Many thanks to Bill Laboon for his daily digest, which helps me not miss some important updates!
