Polkadot Updates

🔴 ⭕️ Relay Chain

  • Runtime v0.9.3 was released as a HIGH PRIORITY upgrade for all relay chain validators. A couple of things to note:

    • Both Kusama and Polkadot validator nodes should upgrade to this release, although for Kusama validators it is more urgent

    • This release sets --wasm-execution Compiled as default. If you've set this flag before you can remove it

    • Polkadot validators can remove the --execution native flag.

    • This fixes some Docker issues with PvF for parachains. Kusama validators that use Docker should upgrade ASAP

  • On 24 May 2021, Polkadot nodes failed with an out-of-memory (OOM) error on block 5,202,216. The issue was resolved and precautions were implemented to prevent this from happening again in the future. Read the postmortem report published by Web3 foundation.

  • In a bid to promote decentralization, Polkadot-JS has been made available on IPFS. will always point to the latest version on IPFS.

🔴 🏛 Governance

  • 📃 Winkrypto published a proposal for discussion: aiming to boost the brand recognition of Polkadot, Kusama and Substrate to a broader audience in Asia-Pacific Region. Polkadot has gained good traction with blockchain audiences but certainly still has room to expand its media exposure and community awareness: "Winkrypto and ChainNews are here to help bring the general awareness of Polkadot to the Chinese speaking community to new levels". The scope of work and budget covering 2021 efforts can be found on this link.

  • Referendum 23, to add a lawyer as a registrar to Polkadot to verify real names, did not pass.

  • 🗳 Referendum 24, to increase the Wasm heap page size, is now up for a vote. The original proposer, RTTI-5220 from Polkadot, has asked for this to be rejected, stating that “the team decided to include heap pages increase on an upgrade and this seems to be the best way to approach the issue - If you vote on this, please be so kind to reject the proposal as it stands now.”

Kusama Updates

🦅 ⭕️ Relay Chain

🦅 🏛 Governance

  • Motion 299 to upgrade the Kusama Runtime to v9030 has passed as referendum 113. The proposal was executed in block #7,668,600.

  • 📃 The second Kusama Town Hall was held on 27 May to discuss Encointer's proposal for a common-good identity parachain. You can watch a recording of the e-meeting here. Encointer has an ambitious plan to give everyone a Universal Basic Income with the goal to create a sustainable, inclusive economy.

  • 📃 VaLibreNetwork has submitted a proposal for Sube v1.0, a library for submitting extrinsics to Substrate-based chains. VLN aims to become Kusama’s "bridge to the real world" by providing the decentralized infrastructure for fiat on-&-off-ramps to the Kusama-verse.

Polkadot Decoded "Gotta Find Them All!" competition has come to an end, and we're ready to announce the results! Check out whether you're among 50 winners to receive Polkadot-branded @Ledger Nano X's 👇

🔩 Core Stack

  • A new Gift pallet is being built by Shawn from Parity. This would allow Alice to “pre-send” some tokens to Bob, who has no idea about Polkadot yet. When Bob sets up an account, he basically uses a “coupon” to transfer some amount from Alice to himself without needing to have DOT for initial transaction fees.

  • If for some reason the validator election mechanism fails like it did on May 24th, instead of freezing the network it will just not try to roll a new set that time, and will reuse the old validator set.
