Ben-Sasson also praised Buterin’s decision to make privacy and quantum-resistant cryptography a top priority.
“Quantum security – excellent,” he wrote on X. “I’m happy to see this as a high priority.”
But he argued that Ethereum should not wait three to four years to get there.
“’3-4 years,’ because the time frame is way too long,” Ben-Sasson said. “Especially for quantum preparation.”
Former Ethereum Foundation researcher Dankrad Feist took a similar tone. Calling the roadmap’s vision “really cool,” Feist said on X that features like near-instant transaction finality and dramatically higher throughput could transform the network.
But his biggest concern was speed. “But 3-4 years is very slow,” Feist wrote. “I think we should be ambitious and get there in about 1 year.”
Feist even suggested that recent advances in AI tools, including large language models, could help accelerate development.
Not all discussions were focused on timing. Some researchers have looked into the technical details of the roadmap.
Ben-Sasson questioned one of Buterin’s proposals to introduce new types of blockchain “states”, essentially data stored by Ethereum on accounts, balances and smart contracts.
“New types of state: what does it mean? Who is affected by it?” he asked, calling for more explanation.
Meanwhile, Barnabé Monnot, a researcher at the Ethereum Foundation, focused on how the roadmap has changed from an earlier version released in February.
