"All cryptocurrencies are not the same. Today, they share a common quantum vulnerability through use of non-quantum safe Elliptic Curve Digital Signature Algorithm (ECDSA) digital signatures yet they have very different risks of quantum attack" "The underpinning digital signature scheme (Elliptic curve) is vulnerable to a quantum computer attack." "Migration to an alternative quantum safe digital signature scheme will require a ‘hard fork’, a non-compatible new blockchain created." https://eprint.iacr.org/2021/967.pdf https://eprint.iacr.org/2021/967.pdf same/related question & answers: https://bitcoin.stackexchange.com/questions/10323/how-vulnerable-is-bitcoin-to-quantum-algorithms https://bitcoin.stackexchange.com/questions/10323/how-vulner...
