The EVM world mostly depends on pre-quantum cryptographic technologies – not just blockchains, but also many existing protocols built on top of and around them. It will still take some time to make EVM chains post-quantum, but these other protocols can often be migrated already. This talk focuses on common problems and solutions encountered when migrating existing protocols to Post-Quantum schemes
At HOPR, we're working on an incentivized mixnet – a privacy protocol for data transport which works offchain but has an EVM-based incentivization layer.
As we start to migrate HOPR towards post-quantum (PQ) cryptography, we’ve run into interesting interactions with pre-quantum EVM chains, which pose questions we believe will apply to everyone who goes down this road.
These questions include: How will security considerations have to change in a PQ world? Is PQ cryptography less practical or weaker than pre-quantum cryptography in certain contexts? Do we need to employ additional measures as a result? How does the efficiency of the protocol change when employing PQ?
This talk will explore these questions and some of our proposed solutions, which we hope can be transferred to other use cases.
