Vitalik updates 2023 Ethereum roadmap diagram: What has changed?

Vitalik Buterin has published a revised version of his 2023 Ethereum roadmap diagram, laying its old items over the Ethereum Foundation’s newer “Strawmap” to show which priorities held and which moved. 

In his X post that was shared on August 10, Buterin said the two diagrams share “a lot of overlap,” but a few things shifted in order of priority. 

Where is quantum safety on the roadmap compared to other items? 

Buterin stated that quantum safety has been up-prioritized. Some other items were deprioritized, though the example he linked was cut off in the post.

When the roadmap was shared in 2023, post-quantum work was just one concern among many.

Then he shrank the emphasis on verifiable delay functions, citing cryptographic weaknesses in existing constructions, and added research topics like obfuscation and delay-encrypted mempools. 

Two and a half years later, the direction has firmed up around defending Ethereum against future quantum computers.

What the Strawmap actually is

The document Buterin overlaid his old diagram onto is the L1 Strawmap, hosted at strawmap.org and maintained by the EF Architecture team of Justin, Thomas, Toni, and Buterin himself.
