It is aligned with the fact that +people putting data into blockchain are financially motivated to put +it into witness data, i.e. into HDD. If miners charge the same per 1 +byte in a transaction output and 1 byte in witness, then people +putting data into blockchain could put it into transaction outputs +(why not, if the price is the same), inflating the UTXO set and making +node operators buy bigger SSD (more costs for node operators). As a +node operator, I prefer the current structure. + +--=20 +Best regards, +Boris Nagaev + |
