ETH Ethereum Foundation's strategic adjustment: Focus on verified cryptographic methods
The Ethereum Foundation announced a major adjustment to its subsequent quantum security strategy, deciding to abandon the use of the Poseidon hash function in favor of more traditional cryptographic methods. Justin Drake, a researcher at the foundation, revealed this strategic shift and said the foundation will prioritize algorithms such as SHA and BLAKE that are widely recognized by academia and proven in practice.
Why abandon Poseidon?
Drake explained that based on recent technological advances, the foundation has reevaluated its initial ideas for deploying Poseidon in post-quantum software, including the advanced virtual machine architecture leanVM. These technological breakthroughs allow traditional hash functions to achieve the same efficiency when verifying computational proofs, thereby weakening Poseidon's previously believed advantages.
Poseidon was originally designed to enhance zero-knowledge proof systems and was considered an ideal choice for future cryptographic deployments. However, Ethereum's new direction will integrate SHA and BLAKE algorithms, both of which enjoy high levels of reliability due to long-term scrutiny in the security field.
Future Challenges and Innovations
The Ethereum Foundation predicts that a production-ready version of leanVM may be operational in 2027, with a full integration plan completed in 2028. This timetable will be adjusted as research and development work progresses.
In making this decision, the foundation worked with academic and industry partners, including Eigen Labs. The company's founder, Sriram Kanan, pointed out that mature hashing methods such as SHA and BLAKE have passed rigorous evaluation and have less potential risks than emerging technologies.
Cooperation with institutions such as Succect, a leader in zero-knowledge certification technology, has significantly improved system efficiency and more than tripled the certification speed.
Poseidon was originally recognized for its compatibility with zero-knowledge proofs.
SHA and BLAKE are seen as safe and mature options in the Ethereum evolution architecture.
Algorithms that focus on academic support reduce the likelihood of unexpected vulnerabilities.
Sri Ram Kanan emphasized that adopting mature hashing algorithms will help Ethereum achieve cryptographic improvements faster. Advances in cryptographic proof have enabled existing hash functions to provide the efficiency needed for large-scale blockchain verification, eliminating the need to rely on more experimental solutions.
Ethereum's commitment to enhanced security is consistent with its macro goal of adapting to the development of quantum computing, ensuring that the blockchain system remains resilient and efficient in the future.
