Title: Can someone please explain this to me?
Post by: weather b0y4 on October 05, 2014, 12:40:25 PM
So i was looking at the top 500 richest bitcoin addresses to see how they changed in the last couple months, and I came across something I do not understand.

The address ranked #153 (was 160) is 1M4vL7mvrKcG2mHas11snsbpktXtqNYJiD

go here and scroll down to 153: http://bitcoinrichlist.com/top100?page=2

It supposedly has 6,309.08 bitcoins in it and has had 725 inputs, but when i search the address on blockchain.info, or click the address from the richlist page, I only see 2 inputs for 0.00001 btc each, and a final balance of 0.00002.

Does anyone know what could be up? I would love to know who is wrong and why.


EDIT: Now when i search the richlist, this address comes up as rank #153, 6,518.6 bitcoins, 728 inputs, but still I only see the 2 0.00001 inputs. (this was only 5 minutes later, and I also found 2 addresses with a last transaction out date of sometime in the last 2 days where blockchain.info shows no transactions whatsoever; the address has never been used)


EDIT 2: searching google for this address brought me to this, which I assume is showing all inputs/outputs.

http://bkchain.org/btc/address/1M4vL7mvrKcG2mHas11snsbpktXtqNYJiD


Well it looks like the address 3MkwFfGNQDve7vz1z6gUDVxkuQpcSV3Mz8  shows all the proper transactions on blockchain.info, so maybe it was just the wrong address being listed on the richlist and this other site in EDIT 2

Coins got moved to another address? Why must anything be "up" for people to move their coins around?

Edit: nevermind, I understand now. My guess is that bitcoinrichlist uses an API that is not very reliable or has some issues with their own software. I think they track every block when it gets broadcasted with blocknotify and a database in the background. If that database is wrong the data shown will be wrong. And apparently its easy to confuse these databases with orphaned blocks as we can see on blockchain.info on a regular basis.

If it was moved there should be an entry of that move on the blockchain. Only thing I can think is that they might have misquoted the key on that 100 rich list.

Yes, I just got it wrong. I edited my post above.

edited first post, looks like some sites are displaying the wrong address

3MkwFfGNQDve7vz1z6gUDVxkuQpcSV3Mz8  multisig addresses tends to confuse said databases. IIRC old versions of blockchain.info just showed "cant decode outputs" or something similar. Its probably something like that.

3MkwFfGNQDve7vz1z6gUDVxkuQpcSV3Mz8
decode to hex
Code:
Header byte: 05 (05 is p2sh, commonly known as multi-sig with a "3" at the beginning)
hash160: dc2047e70aeac3df47eb8a8aa676db7d8efe2278
checksum: 86ea9db1 (for error checking)

1M4vL7mvrKcG2mHas11snsbpktXtqNYJiD
decode to hex
Code:
Header byte: 00 (00 is p2pkh, normal bitcoin addresses with a "1" at the beginning)
hash160: dc2047e70aeac3df47eb8a8aa676db7d8efe2278
checksum: 13dacaa2 (for error checking)


Notice they are using the exact same hash.


I would bet a large sum of money that the rich list does not recognize the 05 header byte (meaning it is not optimized for multi-sig) and just made the address using the hash that was in the output assuming it was a normal bitcoin address.
