Ethereum Foundation Unveils Quantum Security Roadmap for Network Protection

The Ethereum Foundation has taken a crucial step in safeguarding its network against the threat of quantum computers. According to the non-profit organization's research team, four key updates have been proposed to protect the network from future threats.

The first update, known as Fork I, aims to provide network validators with a public key that can be activated in the event of a sudden emergence of a quantum computer. This will ensure that the network remains secure even if a powerful quantum computer is developed unexpectedly.

The second update, Fork J, will reduce gas costs for verifying secure signatures, making it more efficient and cost-effective for users to interact with the network. The third and fourth updates, Fork L and M respectively, will further enhance the network's security by compressing its ability to express blockchain state in zero-knowledge proofs and protecting Layer 2 (L2) networks from future quantum threats.

The transition will affect all three protocol levels: execution, consensus, and data storage. The team plans to complete the network overhaul by 2029, but full migration is expected to take several more years.
