Hot Topics

JAM & Polkadot 2.0 Roadmap

• JAM is a candidate design, it is not Polkadot 2.0
• We clarified the project dependencies to make JAM a reality
  • Alice und Bob summary doc
  • Alice und Bob project tracking sheet

Questions

• Oliver: How can we ensure we get different client implementations
  • Gavin sees two important things: Having a clear spec. And having proper incentives for different implementations
• Bryan: Ways for devs to participate in development?
  • Gavin: There will be a fund for developers that are helping to build it

ISMP as candidate implementation for XCMP

• Seun presented ISMP as a potential implementation of XCMP
• Gavin wasn’t against it :)

Snowbridge

• Vincent from Snowbridge presented the problem of having to set the DOTETH exchange rate regularly in the BridgeHub storage to properly calculate weights for Ethereum transactions.
• Gavin suggested that users have to obtain wrapped ETH to pay for transactions. This way we could avoid complicating designs.
