actually, don't run Knots, run Core..why?
because size of the OP_RETURN in Knots is 40 bytes while in Core is 80 bytes. For true freedom and privacy, Samourai Wallet used this field in Whirlpool activities and it is absolutely essential for the field to be 80 bytes. So if you are pro freedom and privacy stay with Core, despite Whirlpool no longer running since DoJ shackled Samourai Devs. Just need to be patient as Samourai shall rise again!!
Knots was probably agency's version of Core in order to stop Whirlpool which Luke was quite happy to oblige with.
