AI × Crypto Roundup: Agent Payments, Decentralized Compute, Verifiable AI, and On‑Chain Marketplaces

TL;DR – AI agents are beginning to transact, compute, and prove their work on public blockchains, thanks to new payment standards (x402), privacy‑preserving identity layers, and decentralized compute marketplaces.

Agent‑Native Payments Enable Autonomous Commerce
