Functions

func CheckScript 

func CheckScript(ls LockingScript, us UnlockingScript) bool

CheckScript should return `true` to notify that it's a valid combination of transactions

It takes the opt-in's locking script and the other transaction's unlocking script and return a boolean.

func Checker 

func Checker(item interface{}, value interface{}) bool

Checker is a function to be sent to concurrent.Slice.Check to compare transactions. `item` will be the original and `value` will be either the new transaction we're trying to compare or its ID as a `Hash`.

func GenerateFinalOblivion added in v1.1.0 

func GenerateFinalOblivion() (o string, err error)

GenerateFinalOblivion creates the Ω' string, or an error if any
