No redenomination for DOTs, an open source mobile Flutter-based wallet, a directory of Kusama projects, and more!
Thank you for taking the Dot Leap!
We cover Polkadot, Kusama, Substrate, and all related and unrelated Web 3.0 projects!

Story of the Week: Redenomination Proposal
A little over a week ago, Logan Saether of the tech ed team at Web3 Foundation used Kusama’s governance to put forth a referendum.
The goal of the referendum was to gauge people’s opinion on changing the redenomination of DOT. The decimal point would be moved two digits over and all DOT balances would effectively be increased by a factor of 100.
The proposal was explained on Polkassembly.
Fast-forward one week, and the referendum has been the most controversial and most active in Kusama’s short history. Not only was the turnout impressive (way above the officially reported 13% given that W3F and Parity - both large holders - abstained), but the amount of discussion it generated showed us that KSM holders are able and willing to participate in on-chain governance.
The referendum did end up having more Aye votes than Nay votes, but given that the opposition of the minority was so strong and definitely not trivial in numbers, the Web3 Foundation decided not to go ahead with the redenomination until it can be accurately gauged on Polkadot once launched.

Kusama (v 0.7.33.)
Remember a few weeks ago when we mentioned that due to a bug the Kusama treasury hasn’t been getting the fees it should have been getting? Well, that’s fixed now - observe the treasury balance after block 2.2m! Wheee! 📈
🚨 Something I didn’t know! 🚨
When batching transactions (sending multiple extrinsics at once), you can batch a bond and a nomination together. 🤔
In other words, if you’re bonding some tokens with the intent to nominate with them, and you immediately declare validators you want to nominate, it works just fine despite the bonding transaction not having been “mined” yet.
This is because transactions mutate state directly, not after a block is sealed, and so the data needed for the nomination to go through is already there - this is opposite to how other blockchains work. All that matters is that the order of transactions is correct - nomination after bonding.
🏛 Kusama Governance
A new tip has been proposed by Jam for 1000 KSM to Polkawallet. While this may sound like a lot, the result will be a median of endorsements from other council members so 1000 is probably the upper limit. There’s also the fact that Polkawallet deserves it - it’s an open source mobile Substrate wallet based on the highly performant Flutter framework.
Treasury Proposal 19 has been approved at 2000 KSM (~15000 USD at current market value) - originally mentioned in Dot Leap 5, this proposal by UseTech has been a long time in the making and targets a much simpler and more efficient staking user interface for Kusama and other Substrate-based chains.

BlockHashCount is now exposed as a system metadata constant. Your client (UI, wallet, etc.) will now be aware of this value from the chain’s metadata and be able to construct mortal extrinsics accurately regardless of chain. This constant is the number of blockNumber => blockHash mappings to keep around on chain.
This means that when building a mortal (expirable) extrinsic, you can have it be mortal from one to blockHashCount number of blocks. It’ll either expire if set to more than blockHashCount, or be immortal if sent as immortal.
Additionally, this value has been upped from `250` to `2400` which means a typical node of any Substrate-based chain now defaults to keeping the last 2400 block mappings around before pruning.
A new Prometheus metric now allows you to monitor rejected transactions as invalid from the pool:
Substrate CLI now allows multiple log statements. This lets you track a certain target in one mode (e.g. trace) and another target in another (e.g. debug), customizing verbosity of the output to your liking.
Operational and normal weights are now tracked separately. This prevents a deadlock which was previously possible if operational weights got placed into a block first, thereby not leaving room for normal weights.
Transaction versions have been added to signed transactions. This allows hardware wallets to know which transactions they can safely sign.
Successful and failed block imports are now also tracked and can be visualized via Prometheus / Grafana.
Emerald Moonbeam is an open source network crawler for Substrate chains, currently optimized for Kusama. It’ll connect to all available nodes and aggregate all peer data for current network stats and topography visualization. Launch post here.
Polkadot Apps now let you clear expired democracy locks from the Account list, which makes freeing up your funds post-vote a breeze!
Polkadot Apps now display turnout next to the active referendum.
Polkadot Apps now display the threshold and signatories of a multi-signature account in the sidebar if you click on that multi-signature account’s address or name.
Polkadot Apps now support ECDSA key pairs when creating accounts.
