WhoMined.com -- data on which miners mine which blocks

[RangerK]

Hey,

A friend and I just launched this website to try to better keep track of who mines which blocks.  It's not an exact science, but we're going to keep track of blocks based on receiving BTC address, Coinbase signature, and scraping miner websites.

B̶i̶t̶c̶o̶i̶n̶.̶i̶n̶f̶o̶,̶ ̶b̶y̶ ̶c̶o̶n̶t̶r̶a̶s̶t̶,̶ ̶u̶s̶e̶s̶ ̶t̶h̶e̶ ̶I̶P̶ ̶a̶d̶d̶r̶e̶s̶s̶ ̶o̶f̶ ̶w̶h̶i̶c̶h̶ ̶n̶o̶d̶e̶ ̶r̶e̶l̶a̶y̶e̶d̶ ̶t̶h̶e̶ ̶b̶l̶o̶c̶k̶.̶ ̶ ̶A̶l̶s̶o̶ ̶a̶ ̶v̶a̶l̶u̶a̶b̶l̶e̶ ̶m̶e̶t̶h̶o̶d̶.̶

Please let me know what you think.  Suggestions are very welcome.

One change I want to make is to display the data in different ways -- last 144 blocks (day) / last 288 blocks (48hrs) / 1015 (week).

Our analysis goes back to block #285451. You can use the URL to quickly look-up a specific block. For example: http://whomined.com/#301234

Million dollar question, but what's the url? the url is in the thread title AAAND that signals my bedtime. Cool project.

blockorigin.pfoe.be already does this.  Additionally, blockchain.info does NOT use Relay IP for determining which pool mined the block these days.

I didn't know blockchain.info changed their heuristic.  Is there a place I can read about it?

Thanks for this link, handy site to know about!

http://whomined.com/ is nice too OP!

[hydragroup]

could you add an api to return the percentage of what pool is mining?

[RangerK]

We'll do this for sure, but probably not this month.

[RangerK]

Not sure if this will reach anyone (since this is an old thread), but we've made a lot of improvements to http://whomined.com.

For developers --

API:

http://api.whomined.com - return JSON whith last 144 blocks
http://api.whomined.com/#blocknum  - return JSON with 144 blocks from blocknum
http://api.whomined.com/miners - return miners statistic and short info
http://api.whomined.com/miner/<minerid>/<blocknum>  returns last 144 blocks mined by miner staring with

Maybe a stupid question, but could this not be used to determine which cloud mining operations were legit?  A lot of the cloud mining operation threads have accusations of being pyramid schemes.  Something like this could allow a company to prove that they solved a block(s), and thus assure potential customers that they were legit?  Sorry if this is a stupid question, but it appears to be a tool that could become standard for legit companies.

I suppose it can help.  But realize that there is no way to absolutely determine the miner of a block.  (See our discussion: http://whomined.com/#how-it-works)

I think the unique thing we do is make the clues we use to determine the miner public.  So everyone can easily see the receiving BTC address, the coinbase in which some mining pools "sign" their block.

The receiving BTC address of the first transaction in the block is probably the strongest clue.  I can't imagine anyone having incentive to fake it.

Side note:

We can probably get even better by scrubbing more of the mining pool website for their self-reporting (we only do some of them now), but it's a lot of work because each one needs an individual script to parse it, and their websites sometimes change rendering our scripts useless.  We don't have time to do this.  Right now, we're trying to get our games to cover the hosting costs -- and we're still a long way off.  :-)

Sweet site. Great idea snd good stats/info. It is pretty straightforward, but the UX needs work. Design, ad placement, and especially colors need some attention. Let me know if you need help. Thanks & keep it up!

[RangerK]

Thanks!

Right now we're starting to market our games.  If they manage to even cover their hosting cost, we'll look at a serious re-design of http://whomined.com.

Right now, we don't want to invent too much time or any money.  But we're happy to hear specific suggestions.  Proposed CSS revisions are welcome too.  Though all we'll give you is our gratitude (and perhaps a bunch of coupons for http://block777.com).

This is a nice site which showing the type of miner that the person used I think you have to design a new logo and doing some re-design to the site

It's not like the blockchain isn't a public ledger.  Besides, I think most (all?) mining pools are outside of US jurisdiction.

That would be BTC Dig - happened to get an e-mail from them today about that pool finding a block.

Thank you, sir.  We'll add them and start checking for them.

I'll ask someone to PM you a couple coupons to our gaming site -- http://block777.com.

I actually just did a side project for fun to see which pools have mined empty blocks.  It's currently running and when done I will have a pretty concise list.

Looking at your site, I see that you've not included any p2pool stats.  Unfortunately p2pool is pretty tough to figure out, but here's how I do it.  First I parse the coinbase to see if it was Eligius that found the block.  If it wasn't Eligius, then I look at the number of vout in the coinbase transaction.  If there is more than one, I take a look at the very last vout in the list.  If there's no address in that vout, I'm pretty confident that it's p2pool that found the block.
