AI agents are becoming economic actors at a pace that is outpacing the infrastructure around them, according to a16z crypto. In a recent post, the company argued that the real bottleneck in the agent economy is no longer intelligence, but identity.
Today’s agents can carry out tasks and move money, yet they still lack standardized ways to prove their identity, show what they are authorized to do, and more. The company suggests that this missing layer is where blockchain technology could come into play.
From KYC to KYA: a16z makes the case for Onchain identity for AI agents
In a recent blog post, a16z pointed this out Non-human agents indeed Employees outnumber humans about 100 to 1 In financial services. However, agents remain “virtually unbanked.”
“They can interact with financial systems, but not in ways that are portable, verifiable, or trustworthy by default. They lack standardized ways to prove their permissions, operate independently across platforms, or take accountability for the actions they take,” books.

The missing piece, according to the post, is a shared identity layer for customers. This could essentially be the equivalent of SSL that would standardize how formatting is done across platforms.
He noted that the approaches taken today are still fragmented. According to a16z encryption,
“Although there are notable attempts to solve this problem today, these approaches are fragmented: vertically integrated, fiat stacks on the one hand; native, open cryptographic standards (such as x402 and emerging proxy identity proposals) on the other; and extensions of developer frameworks such as MCP (Model Context Protocol) that attempt to bridge application layer identity. There is still no widely adopted, interoperable way for one agent to prove to another who it represents, what it is allowed to do, and how Push it.
The post outlined a major reform called “Know Your Agent” (KYA). This concept borrows from Know Your Customer (KYC). It requires cryptographically signed credentials that link each agent to its principles, permissions, restrictions, and reputation.
The company added that blockchain can serve as… Neutral coordination layer for Agents. They offer portable identities, programmable wallets, and verifiable certificates that are resolved via chat apps, APIs, and marketplaces. Without a common standard, a16z warns, merchants will continue to block proxies in the firewall.

A16Z also identified four additional Gaps beyond identity: Centralized control of AI governance, inappropriate payment rails for agent-to-agent trading, high cost of verifying machine decisions at scale, and diminished user oversight as agents take over more autonomous workflows.
She said that blockchain-based tools, onchain governance, Programmable stablecoin payments, Cryptographic audit trails, and permissions enforced by smart contracts, can bridge these gaps and support a more trustworthy agent economy.
