As with my comment above: you trust the content that is ultimately (up the hierarchy) signed in an IPNS object with a valid signature.<p>And there must indeed by some central authority giving &#x27;ultimate trust&#x27;. This is Zooko&#x27;s triangle. By default IPNS gives you &#x27;decentralized&#x27; and &#x27;secure&#x27;, but you can also opt to tie an IPNS name to a DNS TXT record, and lose &#x27;decentralized&#x27; (at least for the initial lookup) but gain &#x27;human-meaningful&#x27;.
