There was a problem hiding this comment.
Why 19 and not 9?
It is occupied by R0, see ErgoTreeSpecification for method ids checks :
{ import SBoxMethods._
(SBox.typeId, Seq(
MInfo(1, ValueMethod),
MInfo(2, PropositionBytesMethod),
MInfo(3, BytesMethod),
MInfo(4, BytesWithoutRefMethod),
MInfo(5, IdMethod),
MInfo(6, creationInfoMethod),
MInfo(8, tokensMethod)
) ++ (if (isV6Activated) {
Seq(MInfo(19, getRegMethodV6))
} else {
Seq(MInfo(7, getRegMethodV5))
}) ++ registers(idOfs = 8)
.zipWithIndex
.map { case (m,i) => MInfo((8 + i + 1).toByte, m) }, true)
}
