Post-quantum migration is already doable, but the hard part is: who’s going to pay the performance cost first? BNB Chain’s migration test switched transaction signatures from ECDSA to ML-DSA-44, increasing single transaction data size from about 110 bytes to 2.5KB, with throughput dropping by 40%-50%. Solana has also deployed post-quantum signatures on its testnet. @cz_binance @heyibinance, if this upgrade cuts processing speed by nearly half, would you support BNB Chain migrating early, or wait until the quantum threat gets closer? Security needs to be prepared in advance, but users also have to bear the cost of data bloat and performance drops. Bitcoin’s trouble is even bigger. Satoshi Nakamoto is estimated to hold about 1,096,361 BTC, some of which are early P2PK outputs with public keys already exposed on-chain. Once Shor’s algorithm becomes practical, these assets will be the first at risk. MemeBitcoin MBTC @1096361BTC, which just announced an $8M funding round, has turned the quantum risk of Satoshi’s early addresses into a public experiment. Users can generate and test candidate private keys at http://memebitcoin.org. The community has already made over 20 million attempts, with a 1 BTC prize pool up for grabs. The odds of brute-forcing Satoshi’s early private keys are slim, but getting more people to participate hands-on in this security experiment is far more meaningful than waiting to discuss migration after the risks materialize.
