Merge bitcoin/bitcoin#25943: rpc: Add a parameter to sendrawtransaction which sets a maximum value for unspendable outputs.
7013da07fbcddb04abae9759767a9419ab90444c Add release note for PR#25943 (David Gumberg)
04f270b4358417fc2827b9f91717816062b1864e Add test for unspendable transactions and parameter 'maxburnamount' to sendrawtransaction. (David Gumberg)
Pull request description:
This PR adds a user configurable, zero by default parameter — `maxburnamount` — to `sendrawtransaction`. This PR makes bitcoin core reject transactions that contain unspendable outputs which exceed `maxburnamount`. closes #25899.
As a result of this PR, `sendrawtransaction` will by default block 3 kinds of transactions:
1. Those that begin with `OP_RETURN` - (datacarriers)
2. Those whose lengths exceed the script limit.
3. Those that contain invalid opcodes.
The user is able to configure a `maxburnamount` that will override this check and allow a user to send a potentially unspendable output into the mempool.
I see two legitimate use cases for this override:
1. Users that deliberately use `OP_RETURN` for datacarrier transactions that embed data into the blockchain.
2. Users that refuse to update, or are unable to update their bitcoin core client would be able to make use of new opcodes that their client doesn't know about.
