Dot Leap 11
Polkadot's phase 2 begins, Hackusama, the god of all hackathons has launched, version and tool upgrades all around, and governance full speed ahead!
Thank you for taking the Dot Leap!
We cover Polkadot, Kusama, Substrate, and all related Web 3.0 projects!

Polkadot (v 0.8.13)
Polkadot has moved into Phase 2 and is now being secured by a community of third party validators - the W3F validators have been phased out.
The next step is increasing the number of validators in the system and removing the Sudo module. Once this is done, the community can initiate a referendum to activate balance transfers, and Polkadot will finally be fully decentralized. Voting on referenda is now allowed, though only on Council and Technical Committee submitted referenda - public referenda are next!
Kusama (v 0.8.13)
Hackusama, the first-ever hackathon for the Polkadot and Kusama ecosystems, has just started! ~40 more days to submit something awesome!
Seven in Seven
The Kusama treasury funded 7 teams in 7 weeks. We’re at the precipice of a new way of building blockchain tools and communities - on chain, through democracy, and funded by the chain itself. A full report is available in this post by council member Raul.
🚨 Something I didn’t know! 🚨
When nominating, if you set your reward payout destination account to a dead account (one which has not been instantiated by the existential deposit), the reward is burned instead. The system supports payouts only to alive accounts. The UI will now warn of this, but it’s a UI-level fix, so at the protocol level people still need to be careful.
That said, the account will be created if the reward is higher than the existential deposit. Caveat: on Polkadot, that means you need to be staking at least 18 DOT to earn more than 0.01 DOT per era.
Kusama is now running smoothly with 400 validators!
🏛 Kusama Governance
A user accidentally sent their Kusama tokens to their Ethereum address. Council was able to verify that the user owned the Ethereum address and fixed the mistake, moving their KSM to the correct address.
Motion 165 kicks off Forging Block's project for a Kusama Payment Gateway. The motion covers the first milestone of the project. Based on community feedback, the team split the payment by milestones. If passed, we should expect the first delivery at the end of July.
Motion 166 kicks off the vote for Usetech treasury proposal for M2 and M3, discussed this week. It’s sent to Council as
treasury.rejectProposaldue to a large amount of constructive feedback resulting in a UX pivot.
Runtime upgrade motion 168 was made into a referendum and voted into Kusama’s runtime. v2012 runtime includes a staking reward curves upgrade. The ratio on the ideal amount to be staked in Kusama will be now set at 75:25. Here is a summary of that discussion. More information on what the release includes can be found here on the release page.
While auditing/working on migration stuff, Alexander Popiak caught an error in one of the Democracy migrations on Kusama. There were still some old storage items under
Democracy.VoteOf. Shawn Tabrizi opened motion 169 to kill the storage prefix for this item via a Root call to System pallet. Unfortunately, 169 is not propose external (meaning it does not go into the regular queue alongside public referenda). For this, he opened a new motion, 170 with the same goal. 169 has been rejected by the Council, and 170 has been voted in as an external proposal.
Anyone can verify the existing storage items by querying Kusama under the prefix:
0xf2794c22e353e9a839f12faab03a911b02a7afbcd5cd4ad2c68bbc63279ae52ewhich is equal to
xxhash("Democracy") + xxhash("VoteOf"). It was a typo in the migration code that would normally have cleaned this storage up.
Motion 171 is a new runtime upgrade for Kusama which, among other things, includes a bugfix for the transaction pool (see core stack below).

You can now spin up a testnet of two validators and a sentry node with a single command by running the Docker file in
.maintain/sentry-node. Simply run
docker-compose -f .maintain/sentry-node/docker-compose.ymlup and enjoy. A set of monitoring dashboards is also prepared in
( ͡✧ ͜ʖ ͡✧)
A metric for number of transactions propagated to at least one peer has been added.
The atomic swap pallet now supports general atomic swaps. This lets you swap general calls, like for example, trading a SubstrateKitty for a StablecoinToken without going through an exchange.
The staking reward curve has been modified - until parachains are active, the optimal staking percentage is 75%, not 50%.
DataHighway has been approved for SS58 network prefix 33.
🐛 A bug which caused the tx pool to return the same transaction multiple times has been fixed.
A new proxy type - RegistrarProxy - has been added. This allows registrars to execute operations without exposing their main account.
Scheduled tasks can have custom origin now - useful for when you want to allow an entity to schedule a task that affects just some areas of the runtime.

Polkadot JS Apps is at version 0.47.1. Along with the updates in that release, the ones below are important too.
Polkadot JS Apps now default to 1x conviction when voting - take care when voting!
Polkadot JS Apps will now warn you if you try to bond your whole balance, thus locking yourself out of doing further transactions.
PolkadotJS Apps now shows balance info for accounts in the sidebar.
The democracy interface of Polkadot JS Apps now shows you if you voted for a referendum already:
Polkassembly.io now supports switching between Kusama and Polkadot:

The Parachain Implementers Guide now lives online as a static website.
The winners of the Build Polkadot contest have been announced. My personal favorite, milonite’s Network2Network shows trippy visualizations of different addresses and chains in retro and go-crazy formats. Highly recommended!
P2P.org has made a dashboard to monitor the validators that would get in the next set (state is updated every 10 minutes) and estimate the APR of each validator.
Staking4all did a similar thing - web based Phragmen.
The Web3.0 Quora Space is counting almost 500 members already. Are you one of them?
Soramitsu has announced plans to build Polkaswap, a non-custodial token swapping infrastructure which will connect to Polkadot.

That's it for this week - I hope this was as useful for you to read as it was for me to write! Special thanks to Bill for his Daily Digest!
