Dot Leap #4

Run a full node for fun and profit, plus some incredible educational proliferation!

Thank you for taking the Dot Leap!

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

Top News: On-Chain Bounties Soon!

Emiel from Polkascan, arguably the most prolific former member of the Kusama Council, has put forth a suggestion to create a new instrument in Kusama’s Treasury module: Bounties.

Where Treasury Requests are for bigger amounts and the recipient is known ahead of time, and Tips are for minor awesome things, Bounties would be something in between in terms of budget size, but different in realization.

Bounties would have a predefined purpose and amount, but not a recipient. A curator would be in charge of vetting the deliverable, setting the recipient address, and closing the bounty. The curator would also be rewarded for this.

The issue in which the Bounties upgrade is described is here, and this is the accompanying draft PR.

There are still outstanding technical questions. Still, the ability to propose bounties, have them approved by the Council, and have a paid and qualified curator vet the outcome sounds like an incredible ecosystem boon for Kusama.


👇👇👇 Lightpaper Revamp 👇👇👇

An updated version of the Polkadot Lightpaper is out! Read it here:

  • The Westend testnet is now on version 2 after a full reset - keep this in mind if you’re using it in your experiments!

Parachains soon™


Parachain validation function upgradeability is now a thing. Click the image above to see the full resolution of a new skill-tree image of remaining tasks until Phase-1 of parachains is ready. Remember, you can keep an eye on the full process until launch in this roadmap issue.

Kusama (v 0.7.30.) 🎂 2 million blocks!!! 🎂

2 million blocks, yay!

You can now connect to Kusama full nodes through a RYO cloud instance! RYO stands for “Run Your Own” and is a load-balanced setup of community-run nodes exposed to the public.

If you set your Polkadot JS Apps to connect to wss:// you will randomly connect to someone’s node, probably running at home. Decentralization at its finest!

Read more about how this works and other endpoints you can connect to on this page.

🚨 Something I didn’t know! 🚨

A validator can have a maximum of 64 nominators. These are ordered by stake, so the 65th one will not get a payout and is wasting funds on the validator. When nominating, check how many nominators your validator candidates have!

💥 Chaos

For almost a month or so, Kusama’s treasury coffers had been filled less than expected - a bug snuck in during the Lazy Payouts release which basically discarded any remainder of inflation not part of the validator payout.

Jaco swooped in with a quick fix, and now we’re back on track as long as the next runtime upgrade (on-chain) is built from this code when submitted (the 0.7.30 binaries don’t have this in them!).

Technically we could mint the funds we’ve missed out on - they would help with the expenses of the latest treasury proposals too - but that’s all up to the council.

💥 Chaos 2

Certain Polkadot claims were not migrated to Kusama 🙈 the current referendum is to migrate these directly through governance.

SendNodes 💻

Kusama is running a #sendNodes challenge! Run your own full Kusama node (quick guide here) and win swag and money! So. Many. Memes. Details here!

⚠ Updates

🏛 Kusama Governance

  • Now both Polkadot JS Apps and Polkassembly show how many more votes a referendum needs to pass. Polkadot JS Apps goes one step further, showing how many Nay votes are needed to fail a proposal. They do not take into account conviction voting, but it’s a start.

  • Kusama superfan Jam proposed the creation of a multi-person council member, which would vote on matters through a multi-signature setup. Interesting direction to take things in!

  • Referendum 46 of a lone cowboy trying to give himself freshly minted KSM has failed.

  • Treasury council motion 129 to build LocalKSM apps and an ecosystem about p2p KSM trading has passed. Kusama governance has funded an experimental ecosystem development.

  • Treasury council motion 128 to finance LocalCoinSwap to do the same thing is still being voted on, but looks like that will pass too. Never put your experimental eggs in one experimental basket!

  • Emiel of Polkascan fame has created treasury proposals 130 and 131 based on a social contract to fund essential Kusama infrastructure. The motions have passed, for the most part smoothly.
