Every "new use case" bloats UTXO set. OP_RETURN opens up possibility for virtually unlimited, arbitrary nEw UsE cAsEs on Bitcoin.
Restrict the consensus rules so that so-called "OP_RETURN" arbitrary data is disallowed in order to curb bloating of the UTXO set.
Besides, use "datacarrier=0" option in Bitcoin Knots. It blocks the spam from propagation in P2P network mempools and so denies it anonymity.
Bitcoin P2P network is the best privacy tool for monetary transactions.
It is damaged by spamming attacks which are facilitated by Bitcoinβ’ Core and co.
Run Bitcoin Knots instead, set "datacarrier=0".
