so the "checksum" is a few values determined from the series based on a "point system" like going up ladders to then have a series validate that. This opens a new attack surface if they get that algorithm wrong the entire system breaks.
NIST has already approved WOTS signatures and claimed its safe along with checksum
But I think the coding is messy and new signature schemes should be easy to audit. Bad implementation bugs are just as dangerous as bad cryptography even potentially more so!! So I wrote a validation function based on the ORIGINAL Lamport from 1970s or whatever... which suggest to validate the entire message
this is what you would call a "mirror Winternitz" at least in my design. The advantage is it's super easy to market because the verification of signature is probably one of the easiest in the world to verify... my demo is only like under 30 lines of code
the proposal is simple, you hash a hash of something you wanna sign, 64 characters typically for hash
each letter of the 64 characters is hex(16 possible digits 0-9 A-F)
so create a "ladder" of 16 rungs
for each digit hash in series do this 64 times if you have number 0 lets say you are at top of ladder if F at the bottom if 8 in the middle
you can't have hash of 8 and know lower hash of 9... so far so good can go up a ladder but not down
however we need to verify that signature so nobody can forge it after all we do give away the hashes for all 64 characters... they can try to forge it by finding some messages that move UP the ladder, miner throws out your transaction and broadcasts one of his own! So this is where you replace the "checksum" mentioned earlier so no new message can be generated
you create a SECOND ladder the "mirror" that does the OPPOSITE of the first
when attacker moves UP (hash 8 to 7) on any ladder in the series of 64 ladders they must move DOWN on the second series of 64 ladders at the mirror ladder (7 to 6)
since moving down a ladder without knowing the secret is almost impossible this mirror system is secure. At least as secure as any hashing algorithm.
public key is simply the hash of 128 ladder "tops" and secret (private key) is random 128 ladder bottoms. 64 ladders to sign message, 64 mirror ladders to verify
Its post quantum secure. Researching the idea is not novel but the implementation is. It's been suggested maybe once but nobody has done it to my knowledge
Just shows yet again, the simplest ideas are usually the best
Its so simple you can create a visual aid to show a kid. To me that is very good cryptography.

One caveat is the private hashes for that particular public key hash can only be used once. So its deployment would be in a smart contract with millions of disposable keys in a merkle tree

## Explain it like I'm five Update Hey everyone — quick update! ### Pool update The pool now adjusts its position every 1.5 days instead of every 3 days. Before, we waited 3 days because we wanted to be very careful and avoid paying too many trading fees from moving the position too often. But after testing it a lot, we think moving it a little more often should help the pool earn more fees. Why? Because if the pool is out of the best range for a couple of days, it can miss out on profits. Stablecoin pairs usually do not move much, so adjusting every 1.5 days still seems safe and may help squeeze out a bit more profit. --- ## Post-quantum crypto side experiment I’ve also been experimenting with post-quantum cryptography. In simple terms: One day, computers may become much faster. If that happens, some current crypto systems, like elliptic curve signatures, could become weaker. So I’m looking at a different kind of signature system based on hashes. A hash is like a one-way machine: - You can put something in and get a result. - But if you only have the result, you cannot easily figure out what went in. Think of it like a ladder: - Going up the ladder is easy. - Going down the ladder is almost impossible. --- ## The ladder idea Imagine we make a bunch of hash ladders. Each ladder has 16 steps, matching the 16 possible hex characters: 0 1 2 3 4 5 6 7 8 9 A B C D E F A normal hash is 64 characters long, so we make 64 ladders. Each character in the message decides which step of the ladder gets revealed. But there is a problem: If someone sees your revealed step, they might be able to move up the ladder and fake a different message. So we add a second set of ladders. --- ## The mirror ladder The second ladder works in the opposite direction. So if an attacker tries to move up on one ladder, they would also need to move down on the mirror ladder. And moving down is the hard part. That makes forgery extremely difficult. So the system uses:
