It’s been a week in the Nostr ecosystem that feels less like incremental progress and more like a protocol-level earthquake. While the broader crypto market logged its longest winning streak since May—pulling in over $981 million across seven consecutive sessions through July 22—Nostr developers were busy rewriting the rules of what this network can actually do.

The Block Bombshell

Let’s start with the biggest news. On July 21, Jack Dorsey’s Block unveiled Buzz, a free, open-source collaboration platform built on Nostr. This isn’t another social app. Buzz is positioned as a direct alternative to Slack and GitHub, offering channels, threads, code repositories, automated workflows—and perhaps most importantly, native AI agent integration.

“Buzz is a new group chat platform for teams and agents of all sizes, built to reduce our dependency on Slack and GitHub,” Dorsey announced on X.

What makes this genuinely significant isn’t the feature list—it’s the architecture. Every human and AI agent gets its own cryptographic identity on the Nostr protocol. Agents sign their work with their own keys. If an agent’s key is compromised, you can disable the agent without replacing the human identity.

This is the first major enterprise-grade deployment of Nostr as an AI communication layer, not a social network. And it changes the calculus for anyone who thought Nostr was just about replacing Twitter.

Ten New NIPs and Counting

The NostrMag weekly recap, published July 12, captured the moment succinctly: “Nostr isn’t just a Twitter clone. Block turned it into its own AI communication layer. Ten new NIPs just shipped”.

That flood of new NIPs isn’t hyperbole. This week alone saw substantial movement across multiple protocol specifications:

• NIP-47 got a major overhaul, with the core Wallet Connect spec slimmed down and optional features moved to a dedicated extensions repository. The goal: keep the core “small, stable, and easy to implement” while allowing richer features to evolve independently.

• NIP-26 (Delegated Event Signing) defines how events can be delegated to other keypairs, letting users generate new keys for each client while keeping their root key in cold storage.

• NIP-ee introduced E2EE messaging using the MLS Protocol, addressing the metadata leakage problems that plagued earlier Nostr DM schemes. This brings forward secrecy and post-compromise security to Nostr messaging for the first time.

• NIP-38 (User Statuses) enables users to share live statuses—what music they’re listening to, whether they’re working or playing.

• NIP-28 (Public Chat) and NIP-53 (Live Streaming) also saw updates.

That’s not a trickle—it’s a flood. And it speaks to a protocol that’s maturing faster than most observers realize.

The GitHub Sensation

If you want a signal of where developer attention is flowing, look no further than bitchat, which hit #1 on GitHub Trending this week. The project combines Bluetooth mesh networking with the Nostr protocol to create a decentralized, serverless chat app.

The numbers are staggering: 32,770+ stars, 5,138+ forks, and 2,346 new stars in a single day.

What’s driving this? bitchat’s dual-transport architecture uses local Bluetooth mesh for offline communication and Nostr for global reach, intelligently choosing the best path. It works without accounts, phone numbers, or central servers. In an era of increasing censorship and surveillance, that’s not a niche feature—it’s a lifeline.

“bitchat’s rise reflects users’ strong interest in decentralized, privacy-first, censorship-resistant communication tools,” the project analysis notes.

Google Trends: The Quiet Build

Google Trends data tells an interesting story. Nostr currently has a search volume of 22.2K with +433% growth. While user activity may have flatlined since late 2025, the protocol itself is humming with progress.

What we’re seeing isn’t a hype cycle—it’s infrastructure build-out. The kind of quiet, unsexy development that precedes major adoption waves.

The Marmot Adoption

Adding to the protocol’s maturity, the Marmot spec—which enables encrypted group messaging—was officially marked as “adopted” this week, with changes across 42 files. MarmotKit bindings for iOS and Android are now available, signaling that end-to-end encrypted group communication is moving from experimental to production-ready.

Why This Matters Now

I think what we’re witnessing is a fundamental shift in how Nostr is being positioned. For years, it was framed as a decentralized Twitter alternative. But the events of this week suggest something bigger: Nostr is becoming the identity and communication layer for the AI economy.

When Jack Dorsey says Buzz is built for “teams of people and agents of all sizes,” he’s not talking about the future—he’s describing the present. The protocol now supports delegated signing so agents can act on behalf of humans. It supports end-to-end encryption so agent communications stay private. It supports wallet connections so agents can transact.

This is the infrastructure for autonomous AI agents that can communicate, collaborate, and transact without centralized platforms controlling the interaction.

Summary

• Block launched Buzz (July 21): a Nostr-based Slack/GitHub alternative with native AI agent support, marking Nostr’s first major enterprise deployment.
• Ten new NIPs shipped this week, including major updates to NIP-47 (Wallet Connect), NIP-26 (delegated signing), and NIP-ee (E2EE messaging).
• bitchat hit #1 on GitHub Trending with 32,770+ stars, combining Bluetooth mesh and Nostr for decentralized offline-first messaging.
• Marmot spec was adopted across 42 files, bringing encrypted group messaging closer to production.
• Google Trends shows 22.2K search volume with +433% growth, suggesting sustained interest despite flat user activity.

The Nostr ecosystem isn’t just alive—it’s evolving into something its early builders probably didn’t anticipate. And if this week is any indication, the next six months will be anything but quiet.
