## TLDR

Hubble's node count cut from 13k to 10k, with further reductions planned. Alchemy targeting free hubs, mainly airdrop farmers. Hub divergence fixes in progress. Warpcast sync status stable for 7+ days. Storage reduction paused to explore options. Composer actions expanding beyond initial set, now on web. NUX updates include a recommendation algorithm for feeds and improved signup flow. Spam detection enhanced. DC performance and feature improvements ongoing.

## Message Broadcasting

- Issues with job broadcasting at [status.warpcast.com](http://status.warpcast.com/).

- Sync issues between Neynar and Warpcast — working on shuttle improvements for migration.

- Hub performance problems — gRPC timeouts, long write times on Warpcast hubs under heavy load.

## Storage Extension

- FIP: Storage Extension — [github.com/farcasterxyz](https://github.com/farcasterxyz/protocol/discussions/191)

- Goal: Make it easier for users to stay on FC.

- Increasing storage duration for all existing users by 1 year.

- Reducing size of new storage units going forward.

- Rollout soon — no impact on existing users or devs, hubs need to upgrade.

## Sign In with Farcaster

- Positive feedback, but focused on reliability issues for 10-15% who can't scan QR codes.

- Want to improve reliability before expanding (e.g., support for other wallets like Supercast).

- Small changes: shortened SIWF URL and channel tokens to simplify the QR code process.

## Explore Page

- Aiming to make it easier for developers to get users, collecting data for future improvements.

- Potential to add features, such as logging users into the app directly.

## Feed Improvements

- Working on how feed construction changes based on user activity and follows.

- Experimenting with boosting underrepresented content.

- Deprecating power badge by end of August, finding better systems for priority notifications.

- Neynar continues to run a power badge API.

## DC Improvements

- Ongoing performance and feature enhancements.

- Stability improvements first, then focus on APIs and interoperability.

## Time to build is now
