CoinShares Says the Risk Is Real \u2013 but Far From a Crisis<\/strong><\/p>\n<h2 class=\"wp-block-heading\" id=\"h-bigger-signatures-smaller-capacity\">Bigger Signatures, Smaller Capacity<\/h2>\n<p>One of the central issues he raised involves the size of post-quantum cryptographic signatures, which are expected to be far larger than those used today. These expanded signatures could be 10 to 125 times bigger, increasing data demands across the network. As a result, fewer transactions would fit within each block, reducing efficiency and slowing overall throughput.<\/p>\n<p>Beyond performance concerns, Mow pointed to the risk of technical incompatibilities between new and existing systems, which could destabilise consensus and introduce exploitable flaws. He suggested that such disruptions may echo past disagreements over Bitcoin\u2019s scaling approach, particularly the block size conflicts that divided the community.<\/p>\n<p>Mow maintained that research into quantum-resistant solutions should continue, but emphasised that changes must be carefully evaluated before implementation. He noted that quantum computing remains a distant challenge, providing time for measured development rather than urgent intervention.<\/p>\n<p><strong>Related: Bitcoin Treasury Sell-Off Sparks Fears of Crypto Contagion<\/strong><\/p>\n<\/p><\/div>\n<p><script async src=\"\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>Bitcoin,Quantum Computing#Samson #Mow #Warns #Rushed #Quantum #Fixes #Backfire #Bitcoin1775565997<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Samson Mow warns that accelerating Bitcoin\u2019s quantum-resistant upgrades could introduce new vulnerabilities and weaken current security.
