Qu’est-ce que Virtual byte (vB) ?

The unit transaction size is measured in for fee purposes, equal to four weight units, introduced so SegWit data is discounted.

SegWit moved signature data into a separate witness section that counts for one weight unit per byte instead of four. A block holds four million weight units, equivalently one million virtual bytes.

This is why SegWit transactions are cheaper: the same economic action occupies fewer virtual bytes and therefore costs less at the same fee rate.
