Bitcoin puzzles in lower ranges (starting with 66 as of now) can’t be cashed out because of bots and RBF #29793

   Please describe the feature you’d like to see added.

   As you might know, there is this bitcoin puzzle thing going on with the 66th at 10% and the prime candidate to be solved next. It’s guaranteed to be solved within 2-3 years if I’m not mistaken.

   It appears that whoever solves this puzzle first has no way to cash out because as soon as an outgoing transaction is published the public key of the wallet is revealed meaning that a great number of bots monitoring the 66th puzzle wallet pick up the public key, find out the private key within seconds using kangaroo or bsgs and repost the transaction with RBF using higher fee to essentially steal original finder’s funds.

   It is above all unfair.

   Can anything be done about it? The immediate solution that comes to mind is that RBF should be allowed only with the same wallet destination.

   Is your feature related to a problem, if so please describe it.

   Which puzzles? And what does this have to do with Bitcoin Core?

   Usually the issue tracker is used to track technical issues related to the Bitcoin Core code base.

   General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange or the #bitcoin IRC channel on Libera Chat, or one of the Bitcoin subreddits, or any other place that you feel is well suited.

   Network-wide consensus and/or P2P changes first need to be discussed with the greater community, for example https://groups.google.com/g/bitcoindev, or https://delvingbitcoin.org/. Also, they need a BIP to be implemented in Bitcoin Core and other software that connects to the bitcoin P2P network.

   Probably these low entropy private key “puzzels”.

   Can anything be done about it? The immediate solution that comes to mind is that RBF should be allowed only with the same wallet destination.

   This is unrelated to the Bitcoin Core software. Even if Bitcoin Core would limit RBF to transactions paying to the same address, there is no guarantee that other miners and users wouldn’t accept a new version of the transaction (especially if it pays a much higher fee to them).
