&lt;p&gt;A team of specialised AI agents follows a verify before commit pattern: no diagnosis, explanation or transaction is recorded until it has been checked, and verified records are anchored on the Internet Computer blockchain. Farmers can pay for inputs through MTN MoMo, Airtel Money and Zamtel. Climate context comes from CHIRPS, ERA5 and NASA POWER, and the models improve through federated learning with differential privacy, so farm data stays on the farmer&amp;rsquo;s device.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Status:&lt;/strong&gt; In development.&lt;/p&gt;</description></item></channel></rss>
