Key Highlights: Bitcoin proposal BIP-360 alters Taproot spend paths to conceal public keys, but explicitly does not introduce post-quantum signatures or protect exposed keys during transaction broadcast. Ethereum smart accounts can already verify hash-based signatures like SPHINCS+ via the EVM, though native solutions like EIP-8141 frame transactions remain in early draft and testnet stages. Hardware ...
Key Highlights: Google research suggests quantum computers could break exposed Bitcoin public keys in roughly 9 minutes, threatening transactions pending in the mempool during standard 10-minute block confirmations. Over 6 million BTC—worth between $500 billion and $600 billion—sit in addresses with exposed public keys on-chain, while Bitcoin’s proposed BIP-360 upgrade offers risk reduction rather than ...
Key Highlights StarkWare has demonstrated a quantum-resistant Bitcoin transaction method that operates within current protocol rules, requiring no soft fork or network upgrade. The approach uses hash-based cryptography to protect against quantum computers deriving private keys from exposed public keys, but costs approximately $320 in computing per transaction under current implementation. Significant limitations remain: transactions ...
