ACK

Tested with Bitcoin Core 19 and 22 and tested basic DAO use cases.

Left a comment, not sure if that is relevant to address.

Testing:

• PRE: using v21 bitcoind or earlier.
• Setup genesis DAO environment for Alice/Bob.
• Go through 1 cycle with 2 comp requests & 2 votes.
• Make a BSQ transfer from Bob -> Alice.
• Shutdown, take a bitcoind chain snapshot/copy for future test (label it as v21).
• Run JSON seednode export using v21 bitcoind and set the JSON directory aside (marked as v21_run1).
• Repeat above step and set the JSON directory aside (marked as v21_run2).
• Verify JSON directories match using meld: v21_run1 == v21_run2.
• Switch bitcoind to v22 (POST environment).
• Run JSON seednode export using v22 bitcoind and set the JSON directory aside (marked as v22_run1).
• Repeat above step and set the JSON directory aside (marked as v22_run2).
• Verify JSON directories match using meld: v22_run1 == v22_run2.
• Compare JSON directories using meld: v21_run1 == v22_run1.

This PRE/POST test ☝️ is successful with the revised code solution 60db944. If the code is acceptable I can redo the more laborious mainnet test.
