Thank you for taking the Dot Leap!
We cover Polkadot, Kusama, Substrate, and all related and unrelated Web 3.0 projects!

Dot Leap presents: Polkadash
Since last week’s launch of the new educational platform DotLeap.com, we’ve been hard at work polishing some dev resources for dapp and front-end developers who would like to enter the Web3.0 ecosystem. The new content is:
"Polkadot Behind the Code, Episode 1: The Idea", featuring Gavin Wood. Cool video about the origin and development of Polkadot.
Almost 100 accounts have signaled their intention to validate on Polkadot. The sooner we get this number up, the sooner NPoS can be activated. Consider running a Polkadot validator!
The identity pallet has been added to Polkadot’s runtime. This means everyone with some DOT will be able to claim an on-chain identity soon.
Polkadot has already had its first runtime upgrade which was uploaded with this Sudo transaction. Reminder: here’s a video explainer about the Sudo module. This runtime upgrade included a fix for for the "never-ending election" when ForceNone (no new eras) is set, which prevented Proof-of-Stake from kicking off properly. A bug in vested balances was also fixed.
There is an in-repository proposal by Acala to allow a single account to cast multiple different votes. This is already possible, but only if one splits the stash and this cannot be done if the tokens are locked.
Kusama now lives alongside Polkadot in the same code repository, and uses the same binary. To run Kusama, you need to pass in the option
--chain=kusamaor rename the binary to be called
kusama. How exactly it’s possible to run two different chains from the same source code and not have them be identical is explained in this Dot Leap post - special thanks to Jam for putting me on the right track here!
🏛 Kusama Governance
One of the community members has been working on a Proposal for Treasury funding for several media pieces on Kusama, its governance, future, and the current Council. The Proposal has already been voted on and passed in Motion 151.
Referendum 55 to increase validator count to 350 has passed and will be enacted around block 2.635.200. This is the biggest bump in validator slots since genesis.
Liebi’s proposal to add a new registrar has finally turned into Referendum 56, but has been met with some initial resistance. The main complaints right now are that it does the exact same thing as registrar #1 does. I personally think a backup option in case Registrar #1 becomes unavailable or tainted is nice to have.
Council member Kevin Li has proposed an undescribed Proposal 23 in error. He also proposed another registrar in Proposal 24. Due to the error in P23, Kevin proposed a clearing of the active Proposals (23 and 24) which was sped up and enacted by the technical committee in Referendum 57, purging them from the queue. This resulted in the re-creation of P24 as Proposal 25.
Several new Tips are pending confirmation from council in the treasury.
LocalKSM’s second milestone has been funded by the Kusama Treasury and described on Polkassembly.
A new Proposal is being discussed in Polkassembly about integrating KSM into a cross-blockchain clone of Bomberman. Apparently, the game is play2earn and is quite popular.

inspect-node-keycommand has been added to subkey. This prints the PeerId from a node key file.
It is no longer (easily) possible to get proposals that exceed a block’s weight stuck in storage forever. The clear call which clears a proposal no longer looks at weight and length, ignoring all computation costs.
It is now easier to find a block author’s account address using
Existential deposits can now be set to 0 in custom Substrate chains. This goes hand in hand with setups where users will hold many different tokens, but no native currency of the chain, like in Acala’s case.
An implementation of the Overseer has been merged into Substrate. It’s a component acting as a health-checker and message-passing bridge between background jobs (subsystems) in Substrate, explained in detail in the implementors’ guide.
Sentry nodes are now automatically reserved, so
Want to just include PolkadotJS libraries the old-school way in your next project? Use this bundle!
Substrate IDE, a graphical interface for Substrate development on Linux and Mac OS is at release 0.1.1.
Pierre from Parity has released his networking Grafana dashboard for Substrate. It’s what he uses when looking for connectivity problems between nodes, so if you’re seeing connection degradation or need to keep an eye on up time, check out the networking dashboard setup. If you’re unfamiliar with Grafana and Prometheus, I made an intro video, linked below.
You can use the
sub-benchtool to run benchmarks against your
Polkassembly now has comment anchor links so navigating long threads is much more pleasant!
Gantree released an all-in-one infrastructure setup and deployment kit for Substrate nodes and chains - set up a private network in a second!
A great beginner-friendly tutorial to generate a Bitcoin-like blockchain with Substrate and Rust by Nicole Zhu.
"Polkadot for Beginners", an entirely non-technical introduction to Polkadot featuring Bill Laboon and Dan Reecer. Explains the history of the Internet and blockchains, and how Polkadot is the next step in blockchain development.
Darwinia launched the Crab Node Grand Prix: Darwinia Project Moon, 100 Million cRING Grand Prize.
LocalKSM have delivered their first milestone as a Treasury-funded grantee. They are building a local p2p trading experience for KSM tokens, and the flow has been illustrated here and visualized in this video. The docs and implementation are both online, and they even have a Riot group in which one can get in touch with the team.
Over 6000 DAI are up for grabs in the Polkadot Bounty Challenge - Polkadot is live, so time to start building.
Acala just finished their grant milestone which included implementing a stablecoin on a Substrate-based chain, collateralized in Bitcoin and other cross-chain bridged assets, with abstract oracle systems that can support Chainlink integration. The chain comes with a built-in Uniswap-like exchange for instant and fast liquidations.
An paper was posted on arXiv.org which covers various blockchain interoperability protocols, including Polkadot's.
