a charm, and it quickly found the correct nonce value: You might be wondering why I used like inside the where clause to filter the correct result. I quickly realized, however, that it was just reversed! According to the"s page, you can read up to 50 concurrent queries, which can, theoretically, result in up to 50 times faster hashing. Given the impressive scalability of BigQuery, it seemed it could be a good match. Youve got to wonder what wed achieve if we used even a fraction of this computing power for medical research instead. By the way, yes, I understand CPU mining doesn't make much money, I just wanted to see if this was possible. This basically means that if we only vary nonce, we will check 2 possibilities, and our chance to actually find a desired hash is super small: so we need more bytes to play with. I randomly picked one of the recent blocks, number 514868: Bitcoin Blocks At Height 514868, bitcoin blocks at height 0 in the Bitcoin block chain fo, you can get the binary data for this block (hex encoded by clicking on the blocks hash, and then. If we wanted to use BigQuery to mine, wed want use the same set of functions, except we wouldnt have the complete header: we would have to search for a valid header with a small enough hash value.

I m not that familiar with bitcoin mining.
All I know is you need servers for.

The point is, in order to be a successful miner, one has to try different combinations of transaction list and/or vary the time field, in addition to the nonce. A crude calculation shows that even if such a miner was built, when competing with all the dedicated mining hardware running around the world, it would make me roughly 5 a year. This means that we can run the query that we found multiple times, in parallel, each time with a different block header. If you have any concern, please stop using it immediately. But where do we find a block? I've spent several hours pounding my head into a desk for this project. I do not know, I havent tried. 4 Terabytes in less than 30 secs! When I went home after the meetup, I had my BigQuery console open with some analytics query I wrote the day before, and I got this idea: What if I could use BigQuery for mining Bitcoin? The header includes the identifier of the previous block (i.e., the hash of the previous blocks header as well. Then the outer query makes sure we only get values which actually result in a low enough hash which is what we are looking for!
