New Proposal Could Help Ethereum Withstand Future Quantum Threats

The security of a blockchain relies on a simple promise: making the cost of an attack far greater than the expected benefit. This equation has held for over ten years thanks to cryptographic mechanisms considered solid. Yet quantum computing is beginning to shake everything up. The machines that could threaten bitcoin or Ethereum do not yet exist, but progress already made in this field forces developers to prepare for the future. A proposal presented by Nicolas Consigny, manager of the Kohaku project at the Ethereum Foundation, indicates that Ethereum could start protecting its accounts against quantum attacks today for a trivial amount: only 7 cents per account.
