At the Montevideo Blockchain Summit event on July 25th, Ignacio Hagopian, developer of Uruguayan, a member of the Ethereum Foundation (EF), analyzed it in Cryptootics.
After commenting on the role of EF in the Ethereum ecosystem, in this second part of the interview, the Hagopians exposed the estimated entities upon the arrival of a suspicious quantum attack.
“For the Ethereum Foundation, quantum risks come to fruition in 10 or 15 years.”
Ignacio Hagopian, developer of the Ethereum Foundation.
Quantum computing, when mature, promises computational power that can be solved by a second problem.
Among these challenges are specific algorithms that can be theories of Today we will destroy the encryption that protects Bitcoin to Ethereum Many cryptocurrency networks, and general cybersecurity.
In that sense, the Hagopians described the term “10 or 15 years” as far apart, but his vision was different.
“Quantum risks are not far from the point of protocol development. Each Ethereum fork takes time to plan, implement and activate. We are working on what changes we can make to ensure that Ethereum is safe before Quantum Computers.”
Ignacio Hagopian, developer of the Ethereum Foundation.
Today, Ethereum and Bitcoin use encryption based on elliptic curves, an efficient and secure system for traditional computers. However, before quantum algorithms like Shor These mechanisms are vulnerable.
To reduce that risk, Hagopians said they would study the Falcon Signatures scheme, a post-uterine cuosis algorithm based on reticle cryptography (LATICE). To date, it has not been shown to be possible to be destroyed by known quantum algorithms. Another possibility is the use of hash function-based signatures.
According to Hagopian, the Ethereum protocol uses encryption using elliptic curves linked to Blob (Introduced with the Dencun update) This uses the second layer (L2) to register the transaction. It also uses an elliptic curve called BLS. BLS is used by verifiers to vote for the truthfulness of transaction information.
Regarding these technologies: “It’s all going to have to be turned into quantum danger.”warned the developer. Justin Drake, one of the Ethereum Foundation’s most recognized collaborators, recently explained that the network’s data layer will be incorporated over the next decade. «Blobs 2.0» It features post-terage capacity and adjustable size to facilitate the developer experience.
Finally, regarding the number of qubits needed to break Ethereum and Bitcoin security, “it’s a bit complicated. The truth is that no one is very clear,” replied Hagopian.
Cryptonotics explained last July that after progress was made in quantum systems, analysts view the technology as a distant risk considering the amount of qubit needed to break Bitcoin security.
For example, Adam Back, Blockstream Co Founders approximated them as needed. «300 Million Physical Cubits» A survey from the University of Sussex also calculated that 13 million physical qubits would be sufficient to decipher Bitcoin encryption in one day. Meanwhile, today’s most powerful quantum chips have only eight physical Qubits.
