The update plan includes a step-by-step network overhaul.<\/p>\n<p>The existing validator signatures will be completely replaced with hash-based cryptography. A fast hashing algorithm will be selected for the new system, as standard solutions operate slowly.<\/p>\n<p>The network will abandon the current verification system (KZG) in favor of <a href=\"https:\/\/hub.forklog.com\/zk-starks-vs-zk-snarks-razlichiya-v-tehnologiyah\/\">STARK<\/a> proofs. This will require extensive technical work, as the new algorithms are space-intensive. The team will need to optimize information storage.<\/p>\n<h2 class=\"wp-block-heading\">User Wallets<\/h2>\n<p>A new type of transaction with validation and gas fee abstraction (<a href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-8141\">EIP-8141<\/a>) will be added to the protocol. This will allow the use of any cryptographic systems for transaction signatures, not just ECDSA. Quantum-resistant algorithms are bulkier and more expensive. To prevent network fees from rising, the network&#8217;s mathematical computation mechanisms will be updated.<\/p>\n<p>Quantum-safe proofs currently incur prohibitively high fees\u2014around 10 million gas. The solution will be protocol-level aggregation. Transactions will be verified before being included in a block, in the mempool. Every half-second, nodes will send only one &#8220;light&#8221; proof of all computations&#8217; correctness to the main network. This will reduce system load and lower operational costs.<\/p>\n<p>Back in January, the Ethereum Foundation <a href=\"https:\/\/forklog.com\/en\/news\/ethereum-foundation-establishes-post-quantum-security-team\">announced<\/a> post-quantum security as one of its main strategic priorities and formed a dedicated team of developers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ethereum is set to introduce protection against quantum threats.
