Or maybe a bug in block-explorers ?

This address: "16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom"
Has different amounts of bitcoins in different block-explorers!
How can it be possible?

blockchani.info says it has 50BTC
https://blockchain.info/address/16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom
bitinfocharts shows 100BTC
https://bitinfocharts.com/bitcoin/address/16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom
and blockexplorer shows 0.00050026BTC
https://blockexplorer.com/address/16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom

What is going on in here?

Personally I think 100 BTC shown by bitinfocharts is the correct one. Could anyone running a full node check what address: "16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom" has in it?

Interesting find! If I try to import the address into Mycelium (on Android), it crashes first. After a restart it shows 50.00050026 BTC.

http://btc-priceimg.herokuapp.com uses blockchain.info's api: Balance:

https://blockexplorer.com/tx/d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599 shows the 50 Bitcoin created from mining, I haven't used this site before, it seems to not include it when checking the address itself. I'd say that's a bug on blockexplorer.com.

blockchain.info shows both 50 Bitcoin transactions to that address:
block 91812 and block 91842, both have the same txid: d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599.
I read this on I thought trxid is unique. It's fixed years ago:

What's more interesting is this:
Blockchain.info only shows 50btc in the address:
https://blockchain.info/address/16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom
In some sense Blockchain.info is right.  Only one of the two transactions is spendable.  To put it another way, there is only one transaction that just occurred in two blocks.
So who did this just "ignored" 50 deserved coins by overwritting previous unspent ones?
Yes, exactly.  That was presumably a bug in their mining setup (and not done intentionally).
If I interpret this correctly, it means one of these 50 Bitcoins block rewards was never mined. If that's true, the total number of Bitcoins will be 50 less than 20999999.9769! Only 20999949.9769 BTC can ever be created now.

this is a relaly interesting issue you got there.

How did you find this address and why did you start looking for the balance in different block explorers? I'm just curious.

Anyway, I thought at first this was a recently transaction and should need to "stabilize" in the network to show the real value but this is a transaction from 2010 ! Huh

I got no clue

Check out:

https://github.com/kristovatlas/interesting-bitcoin-data/blob/master/README.md

And in particular this:

https://github.com/bitcoin/bips/blob/master/bip-0030.mediawiki

It should help to explain this.

Wow. Good replies to this thread. I now realized, that I should have googled the address before posting. I thought I had found something new.

I was going through a list of old zombie-bitcoins using a script that uses blockchain.info instead of downloading the full blockchain and examining it locally.
Just to see how many zombie bitcoins have come to life after the list was made in 2014.
(The script is quite bad, as it takes a long time to check the list of addresses)

But anyhow among the differences between when the address-list was made and now, there were some odd looking numbers. Among them the  address: "16va6NxJrMGe5d2LP6wUzuVnzBBoKQZKom", where in the list it had 100BTC and now it only had 50BTC and this had happened without a single send action. (I did also notice the other one)

I checked it with other blockchain-explorers, because bitcoin.info handles some other things uniquely too. Eg. If there is a send action from an address to the same address, blockchain.info counts it as moving 0BTC and it not being a send action from the address ??, whereas other explorers show the actual amount moved and it being a send action. Increasing both the amount of coins send and received.
So basically I trust blockchain.info less when there is a difference among blockchain-explorers

And what did I find out when examining the zombie coins. Not much, except that during this year(2017) there have been quite many zombie coins from the beginning of 2011 that have come back to life. I thought that was unexpected, because I would assume that coins that have not been touched since 2011 most probable newer would.
Might have been a little wrong with my assumption...

Thanks for this.  As someone that wasn't around in the early years, these are very interesting transactions.  I've scanned that BIP but I'm going to read it closer now.

Much appreciated.

Can you show a list of addresses that became active after 6 years?

Cant show the complete list, because I didn't save it, but here is a list of addresses that have been created in January and February of 2011, and which have become active recently. (I only examined addresses having more than 100BTC in them)

BTC    when activated    address

1000   2017         12wHYjaPmCtAyorBMQcnJx24ifjZPSy7L2


I would say it is surprising how many BTC, came back to life.
