Linux Foundation

Nvidia and 36 other technology companies have formed the Open Secure AI Alliance to build open-source tools for defending AI systems. The move comes after a breach response exposed concerns around closed AI tools and as crypto networks remain under pressure from attacks that abuse trusted controls.

The x402 Foundation has launched as a neutral open-source venue for companies including Visa, Mastercard, Stripe, Google, Coinbase-linked participants and blockchain groups to shape a standard for AI-driven payments. The protocol aims to let AI agents, machines and users transact over HTTP without relying on subscriptions, advertising models or manual card entry.

The Linux Foundation has launched the x402 Foundation with 40 members, including Ripple, Visa, Mastercard, American Express, Stripe, Google, Amazon Web Services and Cloudflare. The protocol processed about 75 million transactions worth $24 million over the past 30 days, highlighting demand for small stablecoin payments between software agents.
