What is the witness discount?

SegWit weighs witness bytes at a quarter of other bytes, so they cost a quarter as much.

The witness discount is SegWit's rule: a non-witness byte weighs 4 weight units and a witness byte 1, so at f sat/vB a witness byte costs f/4 sats. In the July 2026 measurement run, inscriptions measured 3.374 bytes per vbyte and runestones 1.0000. BVT proposes the discount sells the same resource at a quarter of the price.
