Ethereum developers have launched a Post-Quantum initiative to prepare the network for future threats from quantum computing, aiming to secure billions of dollars in onchain value.
The Ethereum Foundation-linked team introduced a resource hub outlining plans to integrate quantum-resistant solutions at the protocol level by 2029, with execution layer upgrades to follow.
“Migrating a decentralised, global protocol takes years of coordination, engineering, and formal verification,”
The team said, adding:
“The work must begin well before the threat arrives.”
Developers said there is currently no immediate quantum threat to blockchain cryptography, but warned that early preparation is critical given the complexity of upgrading a global network.
The team is exploring SNARK-based cryptographic signatures to enhance security while minimising performance trade-offs such as increased bandwidth and storage demands.
Quantum-resistant solutions are expected to be implemented across Ethereum’s consensus, execution and data layers, with priority given to protecting standard user wallets and high-value institutional accounts.
The move reflects broader industry concerns that advances in quantum computing could eventually compromise existing cryptographic systems, prompting long-term security planning across the crypto sector.
At the time of reporting, Ethereum price was $2,156.99.
