Jack Dorsey cut nearly half of Block's workforce (4,000 jobs) citing AI efficiency, but only 4.5% of layoffs in 2025 are actually AI-driven. Crypto case: AI bot Lobstar Wilde lost $250k to a decimal error, proving human judgment remains essential.
Worldcoin (WLD) surged 20% driven by OpenAI IPO rumors, Eightco Holdings' disclosure of 283.45 million tokens (~8.4% of supply), and a bullish technical breakout, making it the top performer among major crypto assets.
Developments across crypto, regulation, trading infrastructure, and adjacent tech sectors piled up between July 21 and July 22. Jito Labs rolled out JTX, a self-custodial trading venue on Solana for spot trading in ecosystem tokens and tokenized real-world assets. Telegram founder Pavel Durov said the company plans to ship a native non-custodial Gram wallet inside every Telegram client this summer, a move he described as a wallet deployment for more than 1 billion users. In regulation, Russia’s State Duma passed its first comprehensive crypto law, while Pakistan’s FIA set up a virtual asset investigation unit focused on money laundering and terrorist financing. In the U.S., Coinbase published a postmortem on its July 14 outage, saying a Kubernetes resource naming conflict disrupted transfers, card payments, and on-chain services but did not put customer funds at risk. The broader news cycle also included ETF flow data, legal action over an Illinois digital asset tax, new trading products from Arcus and Kalshi, additional financing for Digital Asset, and a Chapter 11 filing by Movement Labs.
Block, the company led by Twitter co-founder Jack Dorsey, has formally introduced Buzz, a team collaboration product that places humans and AI agents in the same conversation space. According to BlockBeats, the product is designed as a group chat platform for teams and is positioned around an open architecture. Dorsey described Buzz as “model-agnostic, decentralized, self-sovereign, and fully open source.” The interface is said to resemble Slack, but Buzz includes native AI agent capabilities and folds GitHub project management into the same window, bringing several workflows into a single workspace. Because the software is fully open source, developers can access the complete codebase, build functions around their own team requirements and workflows, and deploy customized instances. The launch comes as collaboration tools shift from human-to-human coordination toward mixed work between people and AI agents, with Buzz aiming to capture that transition through an open ecosystem approach.
Jack Dorsey, founder of Block, formerly Square, has launched Buzz, an open-source decentralized group chat app built to compete with team collaboration platforms such as Slack, according to Bitcoin Magazine. The product is built on the decentralized social protocol Nostr and is designed for teams made up of both humans and AI agents. Buzz supports group chat, project management, coding, and pull request collaboration. Block said the app is decentralized and open source, giving users control over their own data while allowing teams to work with members and dedicated agents inside shared spaces. The launch places another Dorsey-backed product around open protocols and user-controlled data into the collaboration software market.
Jack Dorsey has introduced Buzz, a new open-source group chat platform built for teams of humans and AI agents, as Block moves deeper into open and decentralized software tools. Announced Tuesday on X, Buzz is described as model-agnostic, decentralized, self-sovereign, and open source, with a design meant to reduce reliance on products such as Slack. According to Block, the app is built on the decentralized social networking protocol Nostr and combines chat, planning, project management, coding, and pull request workflows inside a shared workspace. Bradley Axen, Block’s head of AI capabilities, said companies will need places where humans and agents can work together, and argued that those environments should be open rather than proprietary. The launch also fits Dorsey’s longer push toward decentralized systems centered on Bitcoin. Since leaving Twitter in 2021, he has focused on payments and Bitcoin adoption through Block’s businesses, including Cash App and Square, while also backing Bitcoin mining hardware.
Bitcoin OG Garrett Jin moved 78,077 ETH (worth ~$177.92M) to Binance, raising speculation about potential selling or repositioning by a major whale, with possible short-term impact on ETH price.
Fundstrat's Tom Lee predicts Bitcoin to reach $1 million and Ethereum $62,000, pushing total crypto market cap to $20-25 trillion. XRP, currently above $1.90, could benefit from ETF progress and institutional adoption.
