One Type of Post-Quantum Cryptography Is Most Popular. Why Is Crypto Trying Out Three?

Some crypto products work with multiple chains on different post-quantum paths. NEAR’s Illia Polosukhin and Ledger's Charles Guillemet discuss how they manage that challenge. ======================================================== Thank you to our sponsor! ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Visit⁠⁠⁠ 1inch.com⁠⁠⁠ to swap tokenized securities, crypto and more.

Weeks later, an EigenLayer AI competition improved on that method in roughly 48 hours. Illia Polosukhin, co-founder of NEAR Protocol, and Charles Guillemet, CTO of Ledger, join Laura Shin for an update on the quantum threat whose deadline could be approaching fast. Both are creating products that deal with multiple chains that all have different post-quantum approaches. They discuss why, of the three NIST-standardized, post-quantum algorithms, the crypto industry has splintered into different chains working with different ones, whereas most industries are converging on one, called lattice-based. They also debate what to do with Satoshi Nakamoto's bitcoins: do nothing, freeze them, or freeze and tail-emit new bitcoin, an option Guillemet favors even though Bitcoin's leaderless governance makes consensus hard to reach.
