Post-quantum signatures aren't one-size-fits-all, and now developers can find the SHRINCS setup that fits theirs. Blockstream Research's explorer lets you tune signature size, signing cost, and verification cost to match your wallet, node, or miner. Their sweep of 25,935 candidates found a fallback signature about 2 KB smaller than NIST's SLH-DSA, and 28% cheaper to verify. https://blog.blockstream.com/searching-for-shrincs-parameters/
