@OpenSats , @ODELL , @jack , Brink, @Spiral and other wannabe Bitcoin funding organisations failed. The leading, most important, Bitcoin projects, e.g. Bitcoin Knots, are developed independently and haven't received any funds from the organisations.
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.
