[User] Show me the top 5 NFT collections with the highest floor price on Ethereum, along with their names and contract addresses.

[Assistant] SELECT name, contract_address, floor_price FROM nft_collections WHERE blockchain = 'ethereum' ORDER BY CAST(floor_price AS decimal) DESC LIMIT 5;

[User] Can you also include the banner image URL and filter to only show ERC721 collections?

[Assistant] SELECT name, contract_address, floor_price, banner_image_url FROM nft_collections WHERE blockchain = 'ethereum' AND erc_type = 'ERC721' ORDER BY CAST(floor_price AS decimal) DESC LIMIT 5;

[User] I think there's a typo in your query - it should be 'nft_collections' not 'nft_collections'. Also, can you join this with the nft_metadata table to include the average rarity score for these collections?

[Assistant] SELECT nc.name, nc.contract_address, nc.floor_price, nc.banner_image_url, AVG(nm.rarity_score) as avg_rarity_score FROM nft_collections nc JOIN nft_metadata nm ON nc.contract_address = nm.contract_address WHERE nc.blockchain = 'ethereum' AND nc.erc_type = 'ERC721' GROUP BY nc.name, nc.contract_address, nc.floor_price, nc.banner_image_url ORDER BY CAST(nc.floor_price AS decimal) DESC LIMIT 5;

[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.

[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 AND t1.timestamp >= '2023-10-01' AND t1.timestamp < '2023-11-01';

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

[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 AND t1.timestamp >= '2023-10-01' AND t1.timestamp < '2023-11-01' AND t1.difficulty < t2.difficulty;
