# About the Closed Meeting

- Integration process for Polkadot SDK updates to Runtime
- Fundamental discussion around PVQ

# Polkadot Cloud

- Elastic Scaling (Rob K)
  - in principle ready to launch
  - still working on a feature to prevent latency issues. system is resilient to at leat 1/3 of validators misbehaving
  - no additional runtime upgrades needed. OpenGov runtime feature to be enabled

- NOMT (Rob K)
  - some changes to NOMT to become compatible with Substrate in principle → good progress
  - integrating into Substrate → started

- Basti Blocks (Basti)
  - going through new considerations. E.g. you have 3 cores and want to create 6 blocks, how do you split up blocks between cores?

# Hub

- Smart Contracts (Kian)
  - revive live in Kusama
  - have found some potential issues, e.g. contract sizes might be to big
    - for Polkadot currently exploring supporting PVM and EVM as secondary backend
    - upload PVM bytecode or EVM bytecode
    - details fleshed out, updates will come to the Polkadot forum

- Migration (Oliver)
  - targeting 28th July for Paseo
  - prepared runtimes for Polkadot, then have script to migrate the Polkadot runtimes to Paseo; to ensure the migration to run on Polkadot is properly tested first
  - have special allowance to test on Paseo before Kusama
  - communicated timeline for Polkadot (and Kusama?) might get pushed back because some partners aren’t ready, at least a month
  - Kian: On Paseo, there is the Polkadot Asset Hub. There is also Passet Hub, which was added to test early with smart contracts.

# Next Spammening

- What would be expectations for the next spammening
- Rob K:
  - Kusama: More cores. At least double. But low priority
  - Polkadot: would include more risk. have to be more careful. make it lag behind Kusama

# BLS BEEFY

- needs proof of posession to make the BLS keys secure. Audits and two RFCs have to pass.
- Hyperbridge needs the BLS BEEFY keys to be fully decentralized
