Dot Leap 23

Discussing re-genesis 👶, undoing retrobugs 🐛, a critical DoS fix ⚠, Zug and P2P slashed 🗡, HRMP merged in and parachains V1 added to Cumulus, huge Eth on Polkadot updates, atomic batches, and more!

Thank you for taking the Dot Leap!

👴 Re-genesis 👶

Wei, Parity dev and creator of Kulupu, recently started the discussion around re-genesis functionality in a Substrate-based chain. A re-genesis would “squash” the state of the chain up until a certain point and start a new era from the squashed state, continuing from block 0. So blocks could be uniquely identified only with era-block pairs.

This has the benefit of reducing state and sync size and is a good hard forking mechanism, but has major downsides - UX would degrade, there would be a pause between eras meaning no new blocks would get produced, so every app on every chain would hit a little delay, and it would become difficult, if not impossible, to do audits of past events and extrinsics, often needed for tax purposes.

I don’t think this is a safe play for Polkadot, but I personally wouldn’t mind seeing a re-genesis of Kusama every 5 million blocks or so, keeping it lean and unique, and staying in line with the cutting edge + expect chaos narratives.

Polkadot (v0.8.26.1.)

🚨 Something I didn’t know! 🚨

Because the number of votes for each Council motion to pass differs from chain to chain and is not exposed anywhere via chain metadata (🤪), it falls to UI developers to manually maintain these thresholds. Polkadot JS Apps have this file which is maintained by Jaco for Polkadot and Kusama and Wei for Kulupu 🙈. Any other chain wanting to process their Motions properly via Polkadot JS Apps UI has to contribute to this file.

🐛 Fixing retrobugs - refunds pending!

With the v26 runtime being in Polkadot and v2026 in Kusama, a bug that caused immature slashing of candidacy bonds in council was fixed, and now's the time to proceed with refunding affected accounts on both chains. A full explanation as well as the next steps are documented in these posts: for Kusama, for Polkadot.

The reason they are separate efforts is that the Council is composed of (to a degree) different people in the respective chains and the solution and way forward may differ. Kusama and Polkadot are, after all, each their own universe now.


Polkadot v0.8.26-1 has been released!

Upgrade priority: ❗ HIGH ❗ Please upgrade your node as soon as possible. This change fixes a DoS vector in our p2p networking layer.

Polkadot Governance

For a breakdown of my votes as Council member since the last Dot Leap, please see my Councilor activity reports: Nov 02nd, Nov 5th, Nov 13th.

  • Referendum 10, asking to force_transfer a sum to the alleged victim of a scammer, has failed.

  • Referendum 11 is a fast-tracked runtime upgrade to v26. It passed and has been applied.

  • Referendum 12 is asking to move a claim address. No further information has been provided.

  • Motion 36 and Motion 37 have both passed, approving LocalCoinSwap’s integration of DOT and Ramp’s integration of DOT respectively.

  • Treasury proposal 22 or Motion 39 by Subscan covers operating expenses of the platform on Polkadot from December 2020 to February 2021. A specification of the costs can be found here. I supported this proposal.

  • Treasury proposal 23 or Motion 40 is for Redspot 0.3. The report on 0.2 can be found here. I supported this proposal.

  • Motion 41 cancels proposal 8 as requested by the submitter. I have supported the undoing of this mistake.

Vote for a better tomorrow!

I’m running for Council Member on both Polkadot and Kusama! Read more about why and what I can bring to the table in this post. The writeup also explains how to vote. Remember, voting costs nothing but a transaction fee - and can be done with locked and staked funds - but has the potential to change the landscape forever!

Kusama (v0.8.26.1.)


Kusama v0.8.26-1 has been released!

Upgrade priority: ❗ HIGH ❗ Please upgrade your node as soon as possible. This change fixes a DoS vector in our p2p networking layer.

💥 Chaos

There were numerous equivocations in the last few eras, causing slashing in eras 1457 and 1458. The slashes have been applied and Zug Capital and their nominators have lost some stake. The same happened to the second most represented validator,, in eras 1492 to 1498 but for a much smaller amount.

🏛 Kusama Governance

For a breakdown of my votes as Council member since the last Dot Leap, please see my Councilor activity reports: Nov 02nd, Nov 5th, Nov 13th.

  • Motion 237, by Subscan, covers operating expenses for the explorer on Kusama Network from December 2020 to February 2021.

  • Treasury proposal 55 passed as Motion 236. The proposal was for funding PolkadotAssetJS - the initial version of a Kusama NFT UI app that would hook into RMRK and later native on-chain NFT solutions.

  • I requested more information about the Subbox proposal: a team wants to implement a hosted solution for cargo-remote to allow for faster Substrate compilation.

  • An interesting proposal about adding remarks and reputation weights to treasury proposals and votes has been posed on Polkassembly.

🔩 Core Stack

( ͡✧ ͜ʖ ͡✧)

Currently, validators can change commission at will. There is an ongoing discussion on restricting commission changes (to avoid "commission rug pulls", e.g., changing commission from 0% to 100% after getting enough nominators). The issue is also being discussed on Github where it will be implemented.

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.
