Blockchair is an online service that lets you search bitcoin’s blockchain for anything. Find out how it works today in our Blockchair review.
What Is Blockchair?
Blockchair is an online service found at Blockchair.com. You can use the website’s search form to find any type of information on the bitcoin blockchain.
It’s kind of like a search engine – but for the bitcoin blockchain. You can use Blockchair to find transactions involving over $1 million USD of currency, for example, or check out all the blocks mined by Slush. You can even search for terms like “Marry Me” to find transactions where users have proposed over the bitcoin blockchain.
Blockchair currently only works with the bitcoin blockchain. However, the company plans to add the Ethereum blockchain next, and then move onto other blockchains.
How Does Blockchair Work?
Blockchair maintains a library of all bitcoin transactions, all blocks, and all outputs. That library is completely searchable from the top of Blockchair.com.
You can see the average size of blocks by days and hours over the past few months, getting an idea of when bitcoin payments rise and fall. You can also see hashrate distribution over the past two weeks, or check blocks with the highest fee/kB in USD, the blocks with the most coindays destroyed, and the voting on scalability over the last 2016 blocks. All of this data is aggregated for convenience. Or, you can explore all 477,530 blocks yourself.
Blockchair maintains a library of all bitcoin transactions. You can explore all 241 million+ transactions that have taken place to date. Or, you can see the daily circulation of bitcoins over the past few months, the median transaction fees over time, or the coindays destroyed over the past few months. Blockchair appears to keep transactions just from the last three months.
You can view a distribution of output types over the last few weeks or months. You can also view the percentage of non-monetary outputs over the past few months, or the average fee per kB over the last three months. Or, just explore all 650 million+ outputs manually.
