You'll clearly need bitcoin core or at least it's chain data. Option 1. There are programs like this one (Google result) (https://github.com/graymauser/btcposbal2csv) that parse the chain data and return more usable formats, from csv to proper database. The one I've found returns the addresses with balance. You'll search the addresses there (and if not found then the balance is 0) Option 2. Play directly with bitcoin core with RPC calls. ListUnspent (https://bitcoin.org/en/developer-reference#listunspent) will give you the list of unspent inputs for one or more addresses. You'll have to compose from them the actual balance though.

Post by: aplistir on June 10, 2019, 05:44:41 PM the fastest and easiest way to make unlimited searches without running a node, is to download the current list of all addresses with balances
And then do searches from that file. filesize is only about 900MB. The drawback is obviously that all the results you get are from the moment when the list was generated. If you need to know the balances from this exact second then this is obviously not for you. This thread has info on how to make or get a list of all addresses with balances. https://bitcointalk.org/index.php?topic=267618.320 Title: Re: How to check the balance of the list of 1 million Bitcoin Addresses?

As aplistir say, you can download the file about addys with balance and then compare it with your addys list, You could make an script for this... Lets supose you have your addys on a text file, first you have to download this https://balances.syndevio.com/ ( balances-bitcoin-20190611-0000 (673317892 bytes, 2019-06-11T00:20:22+00:00 - sample) ) Then a code llike: Code: for a in $(cat myAddyList.txt) With this bash script you will generate a file with the addys and balance...

This is extremely inefficient and probably will take quite some time. The fastest approach would be some sort of a perl script. But since the there aren't too many entries in bitcoin-balances, a simple grep would be 'ok', i think: Code: grep -f -F myAddyList.txt balances-bitcoin > final.txt This already is way faster than your bash script, however it is still far away from being really efficient.

I would rather personally use a 3rd party key/value database in order to manipulate small data set like this, like redis. A way to do it would be: First, import database (& go take a coffee, as it will take a few minutes): Code: $ awk -F ';' '{print "SET " $1 " " $2 }' < balances-bitcoin-20190617-0000-foryjL2u | redis-cli >/dev/nullCheck database import by cheching number of keys: Code: $ wc -l ~mycroft/balances-bitcoin-20190617-0000-foryjL2u Then, retrieve all wanted balances & build a k/v export set (where "randomset" is the list of addresses searched in database): Code: $ awk '{print "GET " $1 }' < randomset | redis-cli | tr -d \" > randomset.balancesNot found value would show (nil), which would make easy to know they are not appearing in database.

Code: some script > myAddyList.txt > balances-bitcoin > final.txt Title: Re: How to check the balance of the list of 1 million Bitcoin Addresses? Post by: bob123 on September 16, 2019, 06:34:17 PM is there an alternative script for windows ??? Code: some script > myAddyList.txt > balances-bitcoin > final.txt Sure, just take my example from above: Code: grep -f -F myAddyList.txt balances-bitcoin > final.txt and make a Select-string[1] statement out of it for powershell.

i put some addresses in myAddyList.txt dir: C:\Users\x Code: PS C:\Users\x> findstr.exe -f -F myAddyList.txt balances-bitcoin > final.txt Code: FINDSTR: Cannot open balances-bitcoin Title: Re: How to check the balance of the list of 1 million Bitcoin Addresses?

Did you download it ? Please read the thread from the beginning if you didn't download it yet. Also, you need to adjust the syntax. Windows does not take parameters with a "-" but with a "/" You can find a lot of explanations of findstr online, to properly adjust your syntax. |
