the post-quantum debate is about to fracture crypto into 2 camps
one camp is going hash-based
that's the path
@adam3us is laying out for bitcoin. decades of peer review, conservative hardness assumptions, larger signatures
the other camp is going lattice-based. falcon, or dilithium
that's the path most high-throughput chains will be forced into
because a hash-based signature runs multiple kilobytes and their transactions were sized for a different era
every chain in this debate is going to commit to one algorithm forever, because their architecture gave them no other option
the stablecoins moving across these camps will need a chain that speaks both
every bitcoin holder bridging into defi will need a chain that speaks both
every agent routing the cheapest path through a post-quantum world will need a chain that speaks both
this is why we built
@SuiNetwork the way we did
our chief cryptographer
@kostascrypto shipped the first stateless post-quantum signature for a blockchain in 2017-2018
9 years before this debate existed
when every other chain hardcoded one signature scheme into the protocol, we built an authenticator layer where every algorithm gets a flag
adding a post-quantum scheme means adding a flag, not a hardfork of the chain
while every other chain shrank transactions to fit the cryptography of 2018 and ran out of room
we built transactions with a 100x the space
solana's transactions cap at 1232 bytes. ethereum's gas model penalizes anything larger
sui's transactions cap at 128 kilobytes. that's nearly a 100x compared to solana
sphincs+ at 8 to 50 kilobytes fits. dilithium at 2 to 4 kilobytes fits. falcon at under 2 kilobytes fits
so does any combination of them in native multi-sig
while every other chain is now staring down a forced choice about which algorithm to commit to, we never put ourselves in that position
@adam3us can be right about bitcoin.
@toly can be right about solana. both can be right at the same time
the chain that doesn't have to pick a side is going to ultimately win
and that's
@SuiNetwork
