Tim Beiko posted a roadmap for upcoming #PectraUpgrade for #ethereum blockchain. Key points include:

1. Pectra-devnet-4 is tentatively set to launch by October 17. This is a developer network where teams can experiment with new features.

2. The EL test release (Execution Layer) is expected by October 11, allowing teams to test transaction processing and smart contracts updates.

3. Teams are advised to review the 7702 RPC changes, which involve updates to the Remote Procedure Call protocols used for communication between blockchain nodes.

4. A #BLSBreakout is scheduled for October 14 to finalize the specifications for Boneh-Lynn-Shacham (BLS) signatures and determine gas pricing (transaction fees).

5. The #Pectra Public Testnet is expected to go live before #Devcon , giving users a chance to test new features on a public blockchain test environment.

This roadmap outlines significant milestones for the project leading up to the Devcon event.
