[User] Show me pairs of a block and its previous block where the previous block's difficulty was greater than 100000. Include details for both blocks.

[Assistant] SELECT t1.block_id AS current_block_id, t2.block_id AS previous_block_id, t1.timestamp AS current_timestamp, t2.timestamp AS previous_timestamp, t1.difficulty AS current_difficulty, t2.difficulty AS previous_difficulty FROM blockchain.blocks AS t1 JOIN blockchain.blocks AS t2 ON t1.previous_block_id = t2.block_id WHERE t2.difficulty > 100000;

[User] Okay, now filter those results to only include pairs where the time difference between the current block and its predecessor is less than 600 seconds.

[Assistant] SELECT t1.block_id AS current_block_id, t2.block_id AS previous_block_id, t1.timestamp AS current_timestamp, t2.timestamp AS previous_timestamp, t1.difficulty AS current_difficulty, t2.difficulty AS previous_difficulty FROM blockchain.blocks AS t1 JOIN blockchain.blocks AS t2 ON t1.previous_block_id = t2.block_id WHERE t2.difficulty > 100000 AND EXTRACT(EPOCH FROM (t1.timestamp - t2.timestamp)) < 600;

[User] Further refine the list to only include blocks mined in October 2023.

[User] Finally, from this filtered list, only show pairs where the current block's difficulty is less than the previous block's difficulty.
