Witness Discount
Protocol● Common
A SegWit feature giving witness data (signatures) 75% less weight than other transaction data. Incentivizes SegWit adoption and enables larger effective blocks while maintaining the 1 MB base block limit for non-upgraded nodes.
Technical Notes
Weight = base_size × 4 + witness_size. Max weight: 4M WU ≈ ~1.5-2.5 MB actual. Base block limit: 1M WU (1 MB) for legacy compatibility. Signature data is witness; outputs/inputs are base. SegWit transactions save ~30-40% on fees vs legacy.
