Ethereum has a “clear plan” for post-quantum security involving major upgrades to execution, consensus and even data blobs, explains researcher Antonio Sanso.
Antonio Sanso, cryptography researcher at the Ethereum Foundation, is confident the blockchain will be quantum secure long before a quantum attack is even possible.
”We as the Ethereum Foundation (EF) and Ethereum community are working massively on this topic,” he told Cointelegraph.
“The research part is probably the part that has been already figured out. And we are starting with the execution phase of it. And we’re really confident we’re gonna meet the timeline and the deadline.”
The EF has declared post-quantum (PQ) security a top strategic priority. On Jan. 24, it announced the formation of a Post Quantum team led by Thomas Coratger. Sanso is leading its new biweekly All Core Devs calls on post-quantum security from Feb. 4.
It’s a massive undertaking. He explained that Ethereum’s execution, consensus and data availability layers all need to be upgraded.
”When we talk about having a post-quantum solution, we are not talking about one part — there are all the different big macro areas of Ethereum that need to be migrated,” he said.
