A standard transaction is 225 bytes, leading to a savings of 8.6%. However, that is essentially the minimum saving. For other sizes (eg, 10 outputs) which seem to be pretty frequent savings can be greater. Furthermore, it is important to note that this is a memory saving for the UTXO pool so the

This also fits with the general model that you pay the miners for security. My belief is that when there is a savings benefit to be had large players wi

Rather than re-enable OP_LEFT, a NOP could be re-purposed in a soft fork. OP_DUP OP_HASH160 [pubKeyHash[:LEN_PARAM]] [LEN_PARAM] OP_LEFTEQUALVERIFY OP_DROP OP_CHECKSIG A B L OP_LEFTEQUALVERIFY checks if the leftmost L bytes of A and B match. If not, then the script immediately fails. If either a
