Dot Leap 22
New multiaddress format, Substrate on nix, open source Fearless wallet by Soramitsu, W3F's free and open source identity registrar, a ton of events, and more!
Thank you for taking the Dot Leap!

There’s a bug in the validator election process which prevents nominators with less than ~30 DOT from being effective. For more information read the explanation post!
There is now a W3F Registrar which lets you validate your identity for only 1 DOT.
As Council member, I wrote up my activity report for transparency here.
Referendum 10 seeks to steal back some money from scammers and is currently failing.
Treasury Proposal 11 (for ALEXPROMOTEAM) has moved to Council as Council Motion #23.
Patract Labs’ treasury report post-delivery of Elara 0.1.
A user suggested the redenomination of KSM in a 1:100 ratio just like what happened with Polkadot. This is going to be a tricky sell given that Kusama is its own network and has been in production for a while, so this would cause some confusion across the ecosystem.
It’s even trickier because the proposal is non-binding - it’s just a system remark which doesn’t really do anything per se, only measures KSM holder sentiment towards the idea, so the maintainers would be the ones who would have to implement this. We’ll see how it plays out. As a councilor, I am against the idea purely due to the confusion it would cause.
🏛 Kusama Governance
As Council member, I publish all my decisions in regular posts whenever I act in this official capacity. Here’s the post from October 14th, one from October 20th, and another from October 27th.
I turned Treasury proposal 51 into Motion 226 to support further development of the NFC wallet project.
Motion 227 created the first Kusama bounty - a request for creating a Bounty UI for Kusama. I voted Aye to support the creation of the bounty.
Motion 228 proposed Jaco, the author of Polkadot JS Apps as the curator for a bounty focusing on the development of a Bounty UI addon for Polkadot JS Apps (see above). I agree with the general consensus that Jaco is the most qualified to curate this work, so I voted Aye. The motion ultimately passed but failed to execute because the bounty was not yet funded. It has been subsequently passed as Motion 231.
Motion 229 is a replacement for a motion from a while back which sought to increase the number of validators by 1 every era until 400 new validators have been added in (only this referendum caps this at 100 new validators). The previous referendum passed, but due to an invalid parameter in the scheduler's command wasn't executable, so it ultimately failed. I voted against the previous referendum, something I explained in my report from October 8th. The reason why this is a motion and not a public referendum again is because unclear instructions caused the previous referendum's failure, even though the referendum itself passed. The motion is a correction of that "bug". As such, despite me disagreeing with the ultimate aim of the referendum that will be the result of this motion, I must vote Aye because the referendum already passed previously.
🔩 Core Stack
( ͡✧ ͜ʖ ͡✧)
A new MultiAddress format for Account addresses is coming. This MultiAddress type is a wrapper for different formats that resolve to the same AccountId, so you can use it to target an address by index, raw bytes, hashes of different lengths or, later, human readable names in an ENS-like system.
( ͡✧ ͜ʖ ͡✧)
The import queue now prioritizes finalizing over block import.
The ability to inspect hex-encoded pubkeys has been added to subkey.
The queryStorage and storagePairs RPC calls are now considered unsafe.
wasm-builder now prints out the version of Rust being used to compile the project. This is useful as Substrate cannot be compiled on certain versions of rustc.
Transaction tips now go 100% to the author of the block containing the transaction, as originally spelled out in the research paper.
A nix shell definition has been added to Substrate, to build Substrate with nix.
GRANDPA equivocations should no longer happen with honest nodes that are trying to come back from a failure and aren’t fully in sync with their own past signatures yet. This caused the first Polkadot slash way back in the day and shouldn’t happen again. A slashing reform is also planned which should prevent slashing of benign nodes across the board.
Here’s an ongoing discussion about code rent - currently, uploading an ink! contract needs no rent. Instances of that code pay rent, but the source does not. This new proposal would add code rent.
ink!’s ERC20 example has been revamped to use traits and other best practices!
Going from Council Member to runner-up will no longer cause a slash of your bond. (ouch)
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.
Frontier now supports instant-sealing. This means a block is produced as soon as a transaction is in the pool, allowing for fast testing during local development.
🌟Substrate Sidecar API is at v1! This means old v0 endpoints are no longer supported! 🌟
The Web3 Foundation has released an open source implementation of the W3F Registrar service. You can now also run a registrar to validate on-chain identities using these repos: https://github.com/w3f/polkadot-registrar-challenger and https://github.com/w3f/polkadot-registrar-watcher
offchain-ipfs-manual: A native-level merger of IPFS and Substrate using off-chain workers. Need a blockchain that deals with data storage? This is a good starting point!
Polkadot JS Apps is now at version 0.64 and Polkadot JS API is at 2.4.
Polkadot JS API now has the ability to query all entries at a specific block with
entriesAt. Ever wanted to know all accounts and their balances at a specific block? Now you can.
Upset about the compile times of Substrate? Use a remote compiling SaaS like SubBox.
Soramitsu’s open source Fearless wallet is shaping up for a nice beta test. You can find the source on their organization’s Github:
And link to the apps themselves (early access to beta versions): Android v0.4, iOS v0.4
The Polkadot JS Extension will now auto-extend the “remember password for 15 minutes” window with every new interaction with a chain, as requested by Subsocial’s community. It only makes sense, considering how many interactions one has with Subsocial when using it!

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!
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!
