Bitcoin Block Origin

This site tries to determine which mining pool has mined a certain block.

This site has a database with all known bitcoin pools. We scrape the webpages of those pools to know which blocks these pools have mined. This information is available on these pages.

The blockchain website gives the same information, but it uses a different datasource: it uses the source ip address that first relayed the block. This is not accurate, blockchain contain many errors. This site will only use data which is publicly available from the pool websites, or within the blocks. The quality of the data on these pages depend on the quality of the data published by the pools.

No verifications are made, if a pool claims a block or a block claims a pool, it will be listed on this site. You will sometimes find that more then one pool has found a block. This is ofcourse impossible, but this only indicates that the data on the websites of those pools is incorrect, or perhaps a block has a coinbase implying a certain pool. This site is therefore not error free either, use with caution. Also note that some pools provide the block or generation hashes, others only provide block numbers. Block numbers are not trivial, if a block gets invalidated, this site cannot make the distinction between pools that have mined that block. Therefore, in the block list, pools that are announcing only block numbers are indicated with an asterisk.

If you notice that a specific pool is missing, please contact me, so I can add the pool. You can find me on irc (freenode) with nick kinlo, or email me at kinlo at triplemining.com

This website has the following pages: The block list page shows the last 2016 blocks in our database. The bitcoin network tries to adjust itself so there are exactly 2016 blocks per 2 weeks, so this will show about the last 2 weeks of data found. The chart page visualizes the same data, in a pie chart. The top pools page shows the same data in a table form, so you can see how high any pool ranks
