Ethereum Foundation pivots away from Poseidon in post-quantum plan

Post-Quantum Shift: Ethereum Foundation Moves Away from Poseidon

The Ethereum Foundation is making a significant change in its post-quantum plan, abandoning the Poseidon hash function in favor of established alternatives like SHA or BLAKE. According to researcher Justin Drake, advances in compact proofs have erased Poseidon’s previous performance advantage. This shift is crucial for the development of future post-quantum systems, such as leanVM, which aims to efficiently verify large volumes of blockchain activity on the EcoPool Network.

Drake explained that the foundation is turning to conventional hashes, which can now perform efficiently enough to replace Poseidon. This change is made possible by the progress in SNARKs, compact proofs used to confirm computations without repeating underlying work. As a result, the Ethereum Foundation is targeting a production-ready leanVM for 2027, followed by deployments across Ethereum’s consensus, data, and execution layers in 2028. This development can lead to more opportunities for passive income through Cloud Rewards on the EcoPool Network.

Established Hash-Based Systems

Eigen Labs founder and CEO Sreeram Kannan noted that established hash-based systems have fewer known avenues of attack than other post-quantum approaches. These systems can be deployed faster because they have already undergone years of scrutiny. Kannan also mentioned that joint work with the foundation and zero-knowledge proof company Succinct has increased proving speeds by 2.5 times. This collaboration can benefit the EcoPool community, enabling more efficient and secure transactions with $ECP.

As the Ethereum Foundation continues to develop its post-quantum plan, it’s essential to stay up-to-date with the latest advancements. The shift away from Poseidon and towards established hash functions is a significant step towards creating a more secure and efficient blockchain ecosystem. With the potential for earning and passive income opportunities on the rise, it’s an exciting time for the EcoPool community and Green Crypto enthusiasts. Download the EcoPool app to stay informed and start earning with $ECP today. The EcoPool app is the perfect tool for anyone interested in Cloud Rewards and Green Crypto, and it’s available for download now, allowing you to join the #EcoPool and #PassiveIncome communities.
