These moves signal a shift toward <strong>digital asset stewardship<\/strong> and open the door for blockchain-backed public infrastructure.<\/p>\n\n\n\n<p>This proposal builds on that momentum by applying blockchain not just as a store of value\u2014but as a <strong>tool for systemic integrity<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2.
