Qustion about ETH and BTC etc in a post quantum world, what happens to the 'dead' wallets? I've seen estimates that like 20% of BTC is lost (lost keys, holders incapacitated etc), I assume a fair amount of ETH is in the same position. Assuming forks and wallet upgrades for the liquid coins, wouldn't it still be a huge problem in terms of some actor gaining access to wallets that won't be upgraded? Are there solutions in the works?

in post quantum, there will be a hard fork past which secp256k1 signatures no longer work. @vitalik.eth floated using post-quantum ZKPs to prove you know a seed phrase (many, but not all k1 keypairs are generated from a seed) to authenticate an account.

My technical knowledge is very limited, so forgive a naive question, but wouldn't the Quantum Actor in this case know the phrase?

what is a "quantum actor"? the short answer is no, the scheme V is proposing is secure in principle. it's just somewhat fancy and complicated, and only allows recovery for some EOAs (the ones generated from a seedphrase where the seed is still known) and not others (direct random gen keypair)

if you are curious to understand, good place to start is here--this explains what a seed phrase is under the hood https://learnmeabitcoin.com/technical/keys/hd-wallets/derivation-paths/
