Ben-Sasson also welcomed Buterin’s decision to prioritize privacy and quantum-resistant cryptography.
“Quantum security is great,” he wrote on X. “Glad to see this as a high priority.”
But he argued that Ethereum shouldn’t wait three to four years to get there.
“‘3 or 4 years,’ as the timeline is too long,” Ben-Sasson said. “Especially for quantum preparation.”
Former Ethereum Foundation researcher Dankrad Feist took a similar tone. Calling the roadmap vision “really cool,” Feist said on X that features like near-instant transaction finality and dramatically higher throughput could transform the network.
Their biggest concern, however, was speed. “But 3 or 4 years is too slow,” Feist wrote. “I think we should be ambitious and achieve it in about a year.”
Feist even suggested that recent advances in artificial intelligence tools, including large language models, could help speed up development.
Not all discussions focused on timing. Some researchers delved into the technical details of the roadmap.
Ben-Sasson questioned one of Buterin’s proposals to introduce new types of blockchain “states,” essentially the data that Ethereum stores about accounts, balances, and smart contracts.
“New types of State: what does that mean? Who does it affect?” he asked, asking for more explanation.
Meanwhile, Ethereum Foundation researcher Barnabé Monnot focused on how the roadmap had changed from a previous version published in February.
