Hi Bitcoin Developers,
Address re-use is bad for privacy and such transactions affect everyone
involved. A mempool policy to reject such transactions will be useless,
however packages could be redefined to avoid address re-use in package
transactions.
BIP 331 defines packages as a list of unconfirmed transactions,
representable by a connected Directed Acyclic Graph (a directed edge exists
between a transaction that spends the output of another transaction). With
the new definition, transactions with address reuse cannot be a part of
package relayed by nodes with SENDPACKAGES P2P message.
The only downside that I could think of is the scanning time required to
check address reuse. Maybe others could suggest solutions for this problem
or we can limit the address reuse check only for the chain of transactions.
I am not sure if BIP author would agree with this change and a new BIP wont
make a difference if its not implemented in bitcoin core.
