Unfortunately they don’t offer any size improvements:

```auto
bits 8 16 32 64 128
Flashproofs 385 513 738 994 1444
Bulletproofs 482 546 610 674 739
Bulletproofs+ 386 450 514 578 643
SwiftRange 353 481 610 738 867

```

Grin uses 64-bit proofs, where SwiftRange is significantly larger in size. The paper also fails to compare to Bulletproofs++, which is ony 416 bytes in size for 64-bir rangeproofs.

i see bp++ having 578 bytes from this table, guessing there’s a mistake

didn’t know there’s also a bp+ version so i didn’t pay attention to the number of plusses 😃
