The Ethereum Foundation has released a roadmap for quantum-safe upgrades

Ethereum Foundation Lays Out Quantum Safety Roadmap

The Ethereum Foundation's quantum team just dropped a new roadmap. The initial phase of the network's quantum safety upgrade is expected to wrap up by 2029. That phase includes four key hard forks.

Now, here's the interesting part. Researchers think "cryptographically relevant quantum computing" is still about 8 to 12 years away. But they're not waiting around—the upgrade work has to start early. That's why the foundation set up a dedicated quantum team back in January.

So what are these four forks? The "I" fork gives validators quantum-safe public keys. The "J" fork cuts down the Gas costs for verifying quantum-safe signatures. And get this—both of these upgrades are being considered for inclusion in the Hegota fork later this year.

Then there's the "L" fork, which compresses blockchain state expressiveness into zero-knowledge proofs. And finally, the "M" fork aims to shield Layer 2 networks from future quantum threats. The full execution layer migration? That'll come a few years after all these forks are done.
