Fellowship Updates

Hot Topics

JAM & Polkadot 2.0 Roadmap


  • 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 :)


  • 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.
