AI × Crypto Roundup: Agent Payments, Decentralized Compute, On‑Chain Identities, ZK Verification, and Model Marketplaces

TL;DR

AI agents are moving from experimental demos to real economic actors thanks to on‑chain payment standards (x402, x402‑style rails), decentralized compute networks, tokenized agent identities, zero‑knowledge proof‑based privacy, and emerging marketplaces for AI data and models.
