Dot Leap 17

Kusama-powered NFTs, a parachain launch roadmap, tooling updates all around, a crowdcast for deploying Ethereum apps on Moonbeam, and more!

Thank you for taking the Dot Leap!

We cover Polkadot, Kusama, Substrate, and all related Web 3.0 projects!

Looking for human-friendly explainers and tutorials on how to get started building tools and UIs for Substrate chains? Check out our parent site:

NFTs on Kusama via RMRK.APP!

Tip: if you need a refresher on what NFTs are, this article is all you need.

As announced in the previous edition of Dot Leap, those who share this tweet qualify for a special kind of NFT on Kusama. The NFTs are now live-ish via!

The Dot Leap NFT will allow you special access to swag, early releases of any media (Podcasts, tutorials), and voting power in some decisions Dot Leap (this newsletter) and (the platform) will need to make in the future.

To find out how the NFT works, please go to! It’s a work in progress but pretty far along already!

Polkadot (v 0.8.23)


Rococo now has 8 parachains connected along with an additional candidate. Polkadot JS Apps UI now allows you to explore 7 of the 8 chains (change the network, all parachains are under Testnet→Rococo). If you are interested how far away parachains are, see this roadmap.

Polkadot Governance

  • Motion 10 rejected an erroneous proposal treasury proposal. The proposer re-submitted the same erroneous proposal to setCode. It looks like the UI has a long way to go to make it clear that this is not how things are changed on-chain.

  • Proposal 1 is still undefined and no one knows what it’s supposed to do. Curiously, it’s being seconded by some accounts.

  • A discussion of bumping the validator count and the approaches to take has been opened on Polkassembly. Meanwhile, with only a few days to go, it looks like Referendum 2 to bump the max number of validators in Polkadot is passing.

  • A discussion about funding Centrifuge’s maintenance of a  go-substrate-rpc-client (GSRPC) library for Substrate based chains. The proposal was submitted as Treasury Proposal 7 and passed.

  • Motion 13 is submitted: Polkadot runtime update to v23. Specs of the runtime can be found here. The motion is currently blocked by a pending audit of the new codec for NPoS selection, as you can see in the release notes. As soon as the audit passes, the technical committee will speed up this proposal and get it on-chain.

  • Motion 14 was Polkascan’s Treasury proposal for maintenance of their Python libraries for Substrate. It was approved.

  • The Encointer team’s proposal for a grant to continue the self-sovereign identity and local currencies parachain(s) was up for discussion and passed as motion 15.

  • Motion 16 dealing with the reversal of Web3Italy validator slashes in eras 69 and 70 has passed. You will find a short summary with the main points from the discussion on Polkadot Direction channel here.

  • Proposal 3 is an unknown submitter’s attempt to move an unclaimed DOT amount to another Ethereum address.

  • Treasury proposal 10 has not been clarified by its submitter. The beneficiary is attempting to pay himself 1500 DOT.

  • Proposals 4-7 are attempts to raise the max validator count to 299, 399, 499 and 599 respectively. The proposer has not come forward with details or metrics to substantiate the proposals.

  • Over a dozen tips are pending approval in the treasury.

Kusama (v 0.8.23)

How to Submit a Kusama Treasury Proposal

Looking to submit a proposal to the Kusama Treasury? The Council isn’t an easy group to convince - make sure your proposal is up to standards by following these guidelines!

🏛 Kusama Governance

  • v2023 runtime has been voted in and sped up via technical committee. It was in Motion 213, Referendum 82. Among other things, it included a bump to the number of council members and runners up - both at 19 now!

  • Proposal #32 (referendum 81) to upgrade the runtime code contains a hex-encoded suggestion in ASCII for changing commission calculations, instead of actual runtime code 😬

  • Some tips have been proposed and endorsed. As Council member, I published my activity report card here. Thank you for your vote!

  • Phala Network’s treasury proposal to build milestone 1 of a darkpool on Kusama has passed in motion 212. Full info on the darkpool proposal in this separate thread.

  • There are 3 proposals in queue aiming to increase the number of validators to 700 (proposal 33), 900 (proposal 34) and 1000 (proposal 35).

🔩 Core Stack

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.

  • September 21st: Deploying an Ethereum Smart Contract to Moonbeam, live follow-along Crowdcast as we port a raffle built on Ethereum using standard Eth tools to Moonbeam’s testnet.

  • November 6th: Sign up for TruffleCon and see how easy it is to use Truffle with Moonbeam to deploy and automate your smart contracts as if you never left Eth!

Also, Moonbeam is hiring!

🛠 Tools

  • PokadotJS API now has built-in support for historic queries wherein it auto-injects past metadata when dealing with blocks from a previous runtime. All this means is that it’s *much* easier to query past state from archive nodes now! The queries are a bit slower now, but to speed that up support for hard-coded chain-upgrade tracking was added, so the API doesn’t naively inject metadata into each block, instead it knows in advance when it will have to do so.

🤝 Ecosystem

📅 Upcoming Events and Webinars

  • 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 22nd - European 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 here 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! Special thanks to Bill Laboon’s daily digest for alerting me to many of these novelties!
