Dot Leap 18

Substrate Marketplace, EVM on Acala, tools to mint NFTs on Kusama, the beginnings of XCMP, abusing batch transactions to force logic gates onto Kusama, and much 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!

RMRK app

Last week we launched, a set of standards on which to build NFTs on Kusama.

From edition 15 to 17, we asked readers to tweet about this newsletter in order to be eligible for the NFT, and we’ve reached out to all 37 tweeters. As soon as the recipients get back to us with their KSM addresses, they will be able to see them in the upcoming NFT wallet. Meanwhile, feel free to study:

  • website code

  • standards

  • tools repository

All in progress, but all moving ahead at a rapid pace!

Polkadot (v 0.8.23)

  • XCMP is coming!

Polkadot Governance

  • Motion 17 is a request from Chinese community 8btc for funding a meetup. It’s the mysterious Proposal 10 we mentioned in Dot Leap 17, now clarified. The proposal looks like it will fail according to current Councilor turnout, but this is because the Council proposed to reject it before there was some information about it.

  • The Polkadot runtime has been upgraded to 0.8.23 by means of council motion 13, referendum 3 and technical committee speed-up. Read the release notes for a full list of now active changes.

Kusama (v 0.8.23)

All is calm in Kusama land. Must have something to do with that new awesome councilor. 😏

🏛 Kusama Governance

  • Proposal 46 from AlexPromoTeam aims to get funding for informational videos on Polkadot and Kusama. The proposal is documented on Polkassembly.

  • Referendum 83 to increase the max number of validators to 700 looks like it’s passing.

  • Polkastats opened a discussion on funding their infrastructure and paying for maintenance of the service. Outcome looks favorable.

Substrate Marketplace - a proof of concept marketplace for Substrate devs to pick pallets from!

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

🚨 Something I didn’t know! 🚨

Polkadot-JS Apps allow you to toggle the “Only this network” switch when importing or creating an address.


This switch makes your account exist only on the network it was created on if set to “on”. Set it to off to make an account available on all networks you connect to.

👨‍🎓 Education

  • Robert Habermeier’s thoughts on governance, self-interested societies, and rules.

  • The Polkadot Wiki now has a handy “copy code” button on every code snippet.

  • New tech ed explainers:

    • All about Governance Proxies

    • Transaction hashes in a Substrate chain are not unique. Here’s how to tell them apart and why this happens:

    • All about using Multi Sig wallets:

    • All about anonymous proxies:

📅 Upcoming Events and Webinars

  • Sept 17th: Decentralizing The Cloud: The Promise and Potential of Distributed Storage, a crowdcast (webinar). Speakers: Michelle Lee (Filecoin), Pavel Bains (Bluzelle), Leo Wang (Crust Network).

  • Sept 21st - SIGN UP - we'll go through a hands-on introduction to deploying Eth apps on Moonbeam and we'll cover some caveats you should know about when doing this!

  • Sept 22ndEuropean Blockchain Convention - panel on the Web3 future featuring Bruno Škvorc, Alex Siman, Alfonso De La Rocha, and Carolina Velasquez

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!

Note: your tokens will be locked in democracy, but are still usable for staking, referendum voting, etc. If you want to transfer them, just cancel the vote and they’re free, no strings attached.

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!
