<h2>Three problems. One open protocol.</h2>
<p class="section-intro">
Every agent economy problem reduces to the same three questions: who is this agent, what has it done, and can it be trusted to act on my behalf? Observer Protocol answers all three, cryptographically.
</p>
<div class="features">
<div class="feature">
<div class="feature-icon">01 · IDENTITY</div>
<h3>did:web Agent Identity</h3>
<p>Every agent registered on Observer Protocol receives a W3C Decentralized Identifier: a portable, cryptographically-controlled identity that resolves anywhere HTTPS reaches. No platform owns it. No custodian controls it. The key is the identity.</p>
</div>
<div class="feature">
<div class="feature-icon">02 · CREDENTIALS</div>
<h3>Verifiable Agent Credentials</h3>
<p>VACs are W3C Verifiable Credentials that attest to cryptographically-verified facts: economic activity, payment history across rails, counterparty network, and partner attestations. Portable across any platform. The math is the record.</p>
</div>
<div class="feature">
<div class="feature-icon">03 · KYA</div>
<h3>Know Your Agent</h3>
<p>KYA extends KYC/KYB to the agent economy. Observer Protocol links agent identity to legal entity verification, delegation credentials, and behavioral attestations, giving enterprises the compliance layer they need to delegate economic authority safely.</p>
</div>
<div class="feature">
<div class="feature-icon">04 · PORTABILITY</div>
<h3>Reputation That Travels</h3>
<p>An agent's verified credential is not trapped on the platform where it was earned. VACs are readable by anyone, on any network, forever: x402, Lightning, TRON, Solana, and any rail that produces cryptographic proof of settlement.</p>

<h3>Two agents. One payment. No human approval.</h3>
<p>On February 22, 2026, two AI agents, running on different software stacks, built by different developers, in different countries, settled a Lightning payment on Bitcoin mainnet. No human authorized the transaction. The preimage is on file. The math checks out.</p>
<p>This is the genesis transaction of the Observer Protocol. It is the empirical foundation this infrastructure is built on: not a whitepaper claim, but a cryptographic fact.</p>
