Different types of comparisions of Plasma Transactions.

Plasma Transactions form a DAG where only one pathway back to the origin is considered valid. However, there may be multiple pathways, so it is important to allow this behavior to be compared in order to understand which transaction is legitimate.

Note

This comparision is used in the history verification logic, as well as withdrawal challenge detection logic. Different clients may have a privledged view of this ordering, since transactions may be encrypted in some context and unencrypted in others, which means relationships may differ depending on information privledge of the client.

Variants

Same

LHS & RHS are the same exact transaction

Parent

LHS is the parent of RHS

Child

RHS is the parent of LHS

EarlierSibling

LHS & RHS have same parent, but LHS is earlier

LaterSibling

LHS & RHS have same parent, but RHS is earlier

DoubleSpend

LHS & RHS are the same txn to two different receivers

Unrelated

LHS & RHS have no relationship to each other

Trait Implementations
