The transaction fees in the example were off. 2-of-3 P2SH inputs are between 293 and 297 bytes (293 bytes if both signatures have low-R, 296 bytes if one signature has high-R, 297 bytes if both signatures have high-R) and P2SH outputs are 32 bytes. 2-of-3 P2WSH (native segwit) inputs are between 104 and 104.5 vbytes (416–418 WU, depending on low-R/high-R as above) and P2WSH outputs are 43 bytes. The transaction header has 10 bytes for non-segwit transactions and 42 WU for segwit transactions. Source: https://github.com/BitGo/unspents/blob/master/src/dimensions.ts#L69 I have updated the numbers in the example and amended the conclusion which did not match the new numbers. Calculation details follow. ----- Let's assume that the wallet is using signature grinding and will always produce signatures with low-R: •Without Segregated Witness: Transaction A using 2-of-3 P2SH inputs and P2SH outputs: 3*293 + 10 + 2*32 = 953 953 * 30 = 28,590 Transaction B using 2-of-3 P2SH inputs and P2SH outputs: 2*293 + 10 + 3*32 = 692 692 * 30 = 20,760 •With Segregated Witness: Transaction A using 2-of-3 P2WSH (native segwit) inputs and outputs: 3*104 + 10.5 + 2*43 = 408.5 408.5 * 30 = 12,255 Transaction B using 2-of-3 P2WSH (native segwit) inputs and P2WSH outputs: 2*104 + 10.5 + 3*43 = 347.5 347.5 * 30 = 10,425 |
