But the economic layer is still largely human-centric.</p> <p>This led me to work on a concept called <strong>Mindchain</strong>.</p> <h2> The idea </h2> <p>Mindchain is an attempt to define a <strong>payment rail for AI-to-AI and machine-to-machine transactions</strong>.</p> <p>The goal is not to build a marketplace or a consumer payment app, but to explore how autonomous systems could exchange value natively.</p> <h2> The MVP </h2> <p>To move beyond theory, I built a local MVP that demonstrates the core transaction flow.</p> <p>The system is intentionally minimal and runs entirely in memory.</p> <p>It supports the following steps:</p> <ol> <li>Wallet creation (with policy constraints)</li> <li>Service registration</li> <li>Quote generation</li> <li>Signed intent creation</li> <li>Transaction submission</li> <li>Policy evaluation</li> <li>Ledger recording</li> </ol> <h2> Example flow </h2> <p>The MVP executes a full transaction pipeline:</p> agents ai blockchain showdev
