Polkadot Updates

🔴 ⭕️ Relay Chain

• After Referendum 28 was executed, there is now a nominating minimum of 40 DOT and a maximum total number of 22,500 nominators.

  This change also included a bugfix, allowing nominators to change their validator preferences when the number of nominators is equal to or greater than the maximum allowed.

  It also restricts the use of chill_other, so that if the number of nominators is not near the nominator limits, the chill_other extrinsic cannot be called on other accounts.

🔴 🏛 Governance

• Referendum 26, to increase the number of validators in the active set from 297 to 499, is currently failing, 150,086.55DOT against to 5.61DOT in favor.

• A treasury proposal by DotLeap contributor Gilbert Bassey for a book about Polkadot for blockchain beginners is under discussion.

• Winkcrypto’s treasury proposal to boost the brand recognition of Polkadot to a broader audience in the Asia Pacific region is under discussion.

• The treasury proposal to reward all the activity by the Polkadotters community is under discussion.

Kusama Updates

🦅 ⭕️ Relay Chain

• Around June 30th, Karura and Moonriver, Statemine parachains, stopped producing blocks. The reason was a big extrinsic used on the final day of RMRK’s NFT sale. These extrinsics are used for emoting on NFTs, a feature so popular it has “broken” the chain twice now.

  1/ A quick post mortem of what happened to @KaruraNetwork, Moonriver and Statemine on Kusama block #8138863 and why it took so long for Karura to recover.

  Bryan Chen @XiliangChen

  Yes @KaruraNetwork stoped producing blocks, as well as Moonriver and Statemine due to https://t.co/0OXxU8kaMJ. Good job @RmrkApp the chaos bringer. We are working with Parity on a fix.

🦅 🏛 Governance

• OpenSquare’s proposal for StateScan: a Statemine fungible asset explorer, has passed a council vote. Development has started already and you can check features, timelines and budget on the post.

• The Helikon Team published a proposal aiming to build Subvalt (Substrate Validator Toolkit) for iOS and Android: a native mobile application for iOS and Android devices that provides node operators with tools helping them in running their validators on any Substrate-based blockchain network. It includes configurable notifications about the on and off-chain events, node monitoring features, and validator performance reports.

• Motion 321 is now up for vote! The CryptoLab Team submitted their proposal with the goal of helping non-technical nominators build a stable portfolio and manage it via a well-designed UI (the CryptoLab staking website) and including other tools as well. The platform will integrate both Kusama and Polkadot networks: the first milestone is to be covered by Kusama. Budget, milestones and timelines can be found on the Polkassembly post.

• There is a new Polkassembly discussion about adding an NFT registrar for verifying the originality of certain artists/minters.
