@seoincorporation: thanks for the scripts you provided, but: this should be very time-consuming and slow. Imagine you would run your script against the file of LoyceV which contains all funded addresses (1.8 GB file size). It would take weeks (?) until it gets finished ? what do you think, any ways for optimization ?

Code:

$ cat addyBalance.tsv | cut -f1 | sed '/.\{70\}/d' | sed '/^3/d' | sed '/^1/d' |wc -l
11407170

I know the data is big 1.1 Million addys starting with 1, but i don't think it would take weeks.

I replace cat with head -n 10000, and with the time command i get:

Code:

real	0m37.877s
user	0m31.956s
sys	0m5.951s

So, 10,000 on 40 seconds, that's 4,000 seconds for 1 million, that's 66 minutes, or a little more than 1 hour.

I think it should be faster if you do it all with Python and not calling python from Bash as i did.

Hello LoyceV, i have been working in the Address to HASH160 conversion and i made some scripts that i would like to add to your Linux Commands.

Script to get all the HASH160 from the addyBalance.tsv file from address starting with 1.

Code:

for a in $(cat addyBalance.tsv | cut -f1 | sed '/^b/d' | sed '/^1/d')
do
python3 -c "import binascii, hashlib, base58; hash160 = binascii.hexlify(base58.b58decode_check(b'$a')).decode()[2:]; print(hash160)";
done

Script to get all the HASH160 from the addyBalance.tsv file from address starting with bc1.

Code:

for a in $(cat addyBalance.tsv | cut -f1 | sed '/.\{70\}/d' | sed '/^3/d' | sed '/^1/d')
do
python3 -c "import bech32; hash1 = bech32.decode(\"bc\", \"$a\"); hash2 = bytes(hash1[1]); print(hash2.hex())";
done

Script to get all the HASH160 from the addyBalance.tsv file from address starting with 1.

Run:

You can print the HASH with:

Code:

sh addy.sh

Or oyu can send it to a file:

Code:

sh addy.sh > a.txt

The script prints an error because the first word in the file is 'Addres', but it works fine:

Code:

$ sh addy.sh
Traceback (most recent call last):
  File "", line 1, in 
  File "/home/windows/.local/lib/python3.10/site-packages/base58/__init__.py", line 157, in b58decode_check

And I made a small script for single address too:

sh bc.sh bc1qBitcoinAddress

Code:

python3 -c "import bech32; hash1 = bech32.decode(\"bc\", \"$1\"); hash2 = bytes(hash1[1]); print(hash2.hex())"

sh 1.sh 1BitcoinAddress

Code:

python3 -c "import binascii, hashlib, base58; hash160 = binascii.hexlify(base58.b58decode_check(b'$1')).decode()[2:]; print(hash160)"

You will need the Python dependencies to run this script.

Code:

pip install base58 bech32 binascii hashlib

Addresses with balance=0 AND outputs=0 should not be listed.

No balance and no outputs, that means the address is unused. Those aren't in any of the data dumps.

Quote

Only those matching this condition
if balance>0

That list I have

OR (balance=0 AND outputs>0)

I'm confused: why would the 2 addresses I gave above not qualify for this?

Not really. I am interested in addresses like that:

address, balance, outputs

1aDdressExampLeFundedxXxx, 123456, 789
bc1qnotfundedbutspent0utput, 0, 3

Addresses with balance=0 AND outputs=0 should not be listed. Only those matching this condition

if balance>0 OR (balance=0 AND outputs>0)

Hello all and thanks to LoyceV providing this great ressource of information. For a certain query I'd like to have a file containing all addresses which

either

are funded (=positive balance)

or

had an output in the past (=sent some coins to someone)

Is it possible somehow to generate such a big file with this data which I could use for a query? Alternatively, I don't mind having two separate files: one that already exists and one additional which contains all addresses with outputs. I could run my query agains both of those, that would certainly do the job.

I'm grateful for any helpful information. Thank you so much!

The question would be if you look for double hits per day/per file, or totally in any of files.

The total

For now, I got it covered.
I can try something else too: if I use the list of addresses that are used more than once, it's only 3 GB (instead of 67), and I can search against that list. That was slower in my initial test, but that didn't cause memory problems, and I have to do it less often so it may pay off.

I'm looking for all addresses funded with 1, 2, 4, ...., 8196 mBTC in one transaction, that don't have more transactions than 1 funding and (possibly) one spending. I want to count how many of those chips exist on each day. It could be a good measure for privacy.

I do not understand what do you mean by "directory" - is it a file with addresses? Or directory on hdd where each file has name like an address? Then how you may have the same address twice?

It's a directory with files. Each file has all Bitcoin addresses that were used that day, some of them more than once.

Ok, I understand now. That way I may change program to process all the files from the given directory, not only the one file (daily snapshot). The question would be if you look for double hits per day/per file, or totally in any of files.

If you change your mind, give it a try, maybe it will use less resources. I do not know how much memory will take 8.7mln addresses.

To my surprise, my grep script actually completed! It used up all RAM and added some swap, and after 24 hours of high load, it's done Cheesy

I have prepared a small program for you:
https://github.com/PawelGorny/Loyce60787783
It reads into memory list of addresses and then reads "directory" file with addresses - if address exists in memory, is marked, if the same address in hit for the second time, is removed from memory and saved to file.

Thanks for this! I tried to test it, but I don't really want to install java on the server just for this. I am curious how this would perform though.

I have a file (300 MB) with 8.9 million Bitcoin addresses. I also have a directory (67 GB) with all Bitcoin addresses. I want to know which address from the file is in the direcory more than once.

Main question: how do I put this in .db format?

You don't have to put it in a DB format at all because you can import text files to a data base. The tric is to use tabs and not space betweet the address and the balance.

Code:

echo "hello word" | sed -e 's/ /\t/g'

Once you have changed that, then you can load it in to a table with:

Code:

LOAD DATA INFILE '/tmp/addys.txt' INTO TABLE AddresTable;

Question

I use this:

Code:

grep -hf addresses.txt alladdys/* | sort | uniq -d > output.txt

For small lists of addresses, this works fine! However, with the 300 MB list, grep takes 94% of my 16 GB RAM, and there doesn't seem to be any progress. I didn't expect grep would use this much memory for a 300 MB file.
What would be a better solution?

Thanks! I only now realize I can just add all balances for each address, and sum them later when needed.

The drawback of such a versatile database is that I have a lot of catching up to do. Thanks for the links, I'll see if I can get something working tomorrow

Update: I don't need a database anymore, I'll stick to what I know: clear text

Mysql is also good, they give https://www.mysql.com/products/workbench/
I will not force you to install MS SQLServer or any monster from Oracle.
Let's say you decide to use postgresql. Then you receive a very nice client - pgAdmin https://www.pgadmin.org/ Using tool like that will be very helpful for you.

Then you may for example: create table (tx id, address, balanceChange),
txid could be our primary key (unique), you should also create index on recipient, as you will launch search using that field.
load data:
https://sunitc.dev/2021/07/17/load-csv-data-into-a-database-table-mysql-postgres-etc/
(create index after you load data, otherwise loading will take ages)

Then you may very easily check balance change (delta) for each recipient:

Code:

select address, sum(balance) from tableName group by address

It should give you list of addresses with their balance changes.

Just try to list all the possible use cases, think what do you need, how you want to use it - to build a correct data model. It may be the most difficult task - just not to duplicate data, etc
https://www.guru99.com/relational-data-model-dbms.html
https://en.wikipedia.org/wiki/Database_normalization

But if you start, sky is the limit Wink

it will be much easier than playing with text files.

Why not to launch mysql or maybe better postgresql server? Loading file like that to database table is trivial.
RAM has nothing to do with that I think. I mean - it helps, but is not a blocking constraint.

I've heard of mysql, but not PostgreSQL.

"Trivial" sounds great Cheesy

But I have no idea how Tongue

Google shows this, if that's the right track I can try it.
Any idea how to handle duplicate addresses: 1 address with 2 balances that have to be added together?

@iceland2k14: thanks, but it feels like I'm in over my head. I've abandoned the pubkey project (at least for now).

It looks like I'm going to need to learn using a database.
Let's say I have a list like this:

Code:

sender recipient value fee

Want I want, is a database that only contains Addresses and their Value. To get this, Value and Fee get subtracted from Sender's balance, and Value gets added to Recipient's balance. The input data will be around 200 GB, including many duplicate addresses.

Given that I know nothing about databases, how would I start doing this? Is it going to be a problem if the database is larger than my RAM? If needed, I can (easily) split this list up into 2 lists: one with Sender, Value and Fee, and the other with Recipient and Value.

Sorting is going to be slow for the full data set, and probably takes about 500 GB tmp space, but it's doable if it helps.

Main question: how do I put this in .db format?

@LoyceV The Values in Sigscript (Contains R,S, Pubkey) is not fixed but they have defined structure. One piece of the Structure is As shown by @MrFreeDragon in this Link https://pastebin.com/Q55PyUgB
But even in this structure the length is not always 0x21 or 0x20 or 0x41. it varies and therefore the length of R and S and Pubkey will vary. You will need to use dynamic sizing variables to extract them. Perhaps use a Awk script or Python. That might be easier. Don't know if the Bash Shell can do all of it.

The basic way to decode and extract the variable size of the data can be taken by following code below...

Code:

def get_rs(sig):
   rlen = int(sig[2:4], 16)
   r = sig[4:4+rlen*2]
# slen = int(sig[6+rlen*2:8+rlen*2], 16)
   s = sig[8+rlen*2:]
   return r, s

def split_sig_pieces(script):
   sigLen = int(script[2:4], 16)
   sig = script[2+2:2+sigLen*2]
   r, s = get_rs(sig[4:])
   pubLen = int(script[4+sigLen*2:4+sigLen*2+2], 16)
   pub = script[4+sigLen*2+2:]
# assert(len(pub) == pubLen*2)
   return r, s, pub

r, s, pub = split_sig_pieces(script)

Code:

script: 8b4830450221008bf415b6c4bc7118a1d93ef8f6c63b0801d9abe2e41e390670acf9677ee58e5602200da3df76f11ae04758c947a975f84dd7dba990e00c146b451dc4fa514c6cb52d01410421557041f930252b79b0fa28e6587680053b3a3672ff0c1dca6a623c79bdc0b6125a7a2be5450e28e49731ba8f60231dd8eceeff170923717d97a1ca5a67acd4
R: 008bf415b6c4bc7118a1d93ef8f6c63b0801d9abe2e41e390670acf9677ee58e56
S: 0da3df76f11ae04758c947a975f84dd7dba990e00c146b451dc4fa514c6cb52d
pub: 0421557041f930252b79b0fa28e6587680053b3a3672ff0c1dca6a623c79bdc0b6125a7a2be5450e28e49731ba8f60231dd8eceeff170923717d97a1ca5a67acd4

This way you can not only extract all the Pubkeys but can also extract all the R & S values of the Signature, if needed.

That is a good idea. You'll have to search for both the uncompressed and compressed keys in the list.

It is not like leading zero removed somewhere during the process?
I though pubkeys should always have 65 or 33 bytes (including the one for flag).

I'm not sure. If there are leading zeros when the pubkey is "shorter", I may be able to include them by simply counting from the right instead of from the left.

Keep the records that are 131 and 66 characters long. 131 chars are for the uncompress pubkey and 66 chars for the compressed pubkey. The uncompressed pubkey prefix is 04 and the compressed pukey is 02 or 03.

This one is 130 characters:

Code:

0405eec604993048314294f7c1f9b45c3ed8424ef940426336153831f8813228a788f845e1df353c2021174573e33f2fab05d94e1dd5e5449832ec83ac3d5db17e

The compressed ones are indeed only half the size. But I meant the ones where the length varies by only 2, which is probably caused by truncating the first 148 characters.
Could it be the 148 characters isn't always the same?
Compare those 2:

Code:

It seems like it's not always 148 chars that can be truncated.

It seems like it

Combined with the fact that only a part of the spending_witness data is the pubkey, and that the pubkey length itself can vary, I don't know how to proceed. If you can figure it out, I'll continue this, but I don't have the time to search for it myself now.

Hi, I have no idea why it is doing that.

Is it possible to keep with one of the lines?

I'd need to know which one to keep, and even better: how to decide that from the raw data. The current output is 81 GB (815,497,912 lines), which is too large to sort on this server (only 93 GB disk space remaining). Sorting is needed to remove all duplicates, which is needed to reduce the file size before checking for addresses with a balance.

Hi, I have no idea why it is doing that.

Is it possible to keep with one of the lines? I'd probably guess that the address will be empty anyways or might have to do some manual on the data and the final comparison for a positive balance.

Yes, I'm looking for spending_signature_hex. Sorry about the mixup.

I'm currently running this:

Code:

for day in `ls inputs/*gz`; do echo $day; gunzip -c $day | cut -f7,8,18 | grep -v spending_signature_hex | grep pubkeyhash | grep -vP "\t$" >> output2.txt; done

~~If it doesn't run out of disk space, I'll continue from there tomorrow.~~ It won't fit for sure Sad

That's going to be a problem, because I need a few times more disk space to sort the data. 1 TB might not even be enough.

This is a bit smaller:

Code:

for day in `ls /var/www/blockdata.loyce.club/public_html/inputs/*gz`; do echo $day; gunzip -c $day | cut -f7,8,18 | grep -v spending_signature_hex | grep pubkeyhash | grep -vP "\t$" | cut -f1,3 >> output2.txt; done

MrFreeDragon already described what we're looking for here.

I'll try this:

Code:

for day in `ls /var/www/blockdata.loyce.club/public_html/inputs/*gz`; do echo $day; gunzip -c $day | cut -f7,8,18 | grep -v spending_signature_hex | grep pubkeyhash | grep -vP "\t$" | cut -f1,3 > /dev/shm/tmp.file; paste <(cat /dev/shm/tmp.file | cut -f1) <(cat /dev/shm/tmp.file | cut -f2 | cut -c149-) | sort -u -S40% >> output2.txt; rm /dev/shm/tmp.file; done

Explanation: it truncates spending_signature_hex to only the pubkey (I used a detour, but it works without reducing performance much). This reduces the size, and I can remove duplicates for each day already. That should reduce the output size.
I'll let it run overnight.
Update: This produces different results:

Code:

1zxhKVZtMBt8kf7km2shn2mkR4NLHGigT 0405eec604993048314294f7c1f9b45c3ed8424ef940426336153831f8813228a788f845e1df353c2021174573e33f2fab05d94e1dd5e5449832ec83ac3d5db17e

Somehow the 148 characters isn't a constant.

Any idea why? The pubkey doesn't seem to have a fixed length either, so counting characters from the end won't work.

Kindly let it process all the blocks up to the current one.

Thanks again

Can you process the inputs data dumps by extracting the following columns from them: recipient, type=pubkeyhash only, spending_witness.

I did this:

Code:

for day in `inputs/*gz`; do echo $day; gunzip -c $day | cut -f7,8,19 | grep -v spending_witness | grep pubkeyhash | grep -vP "\t$" >> output.txt; done

It's still running (and will take many hours to complete), but up until 2014, there is no output at all. I'll let it finish to be sure.
Update: as expected: no output.

Are you looking for "483045022069e95f67cc6fed7db01885d76e3294e443d9833316228bbd057f0f3a3bdd516302210 09ef89fa8c34f37a245333c67d56feaef27b26651c4a30b6499e1bc386337ca8f0141047a51392b ace353f4c3788c9c090ef4f635ec211159ec3b9f1bb7da7679517e126e98e0012bcb4d2b023c479 afaaa1ad703ea1b24e1910e2cdad38744ba7aab8a"? That's not spending_witness, it's spending_signature_hex. For pubkeyhash entries, spending_witness is empty (there are double tabs in the .tsv file without any data in between, so without using a spreadsheet it's easy to overlook).

Hi LoyceV,

Can you do something similar to what you did for the outputs? Can you process the inputs data dumps by extracting the following columns from them: recipient, type=pubkeyhash only, spending_witness. Once done, remove duplicate entries and cross-reference with the "List of all funded Bitcoin addresses" keeping only the recipients with a positive balance. Compare the recipients with balance_addy_pubkey.txt and the difference will be the results I'm looking for. The spending_witness will contain the pubkey of those pubkeyhash addresses (truncating the 1st 148 characters will leave only the pukey remaining).

The instructions would be useful too.

Regards,

Get pubkeys out of Bitcoin block data (this was requested here).

Note: this list is not meant for verbatim copy/pasting, it's my own notes of what I did (more or less).

Get outputs data (currently 148 GB)

Code:

wget -r blockdata.loyce.club/outputs/

Get all addresses with pubkey

Code:

for day in `ls outputs/*gz`; do echo $day; gunzip -c $day | grep -v is_from_coinbase | grep -v pubkeyhash | grep pubkey | cut -f 1,2,4-11 >> output.txt; done

(output.txt includes more columns than strictly needed)

Get currently funded Bitcoin addresses and their balance (1 GB)

Code:

wget addresses.loyce.club/blockchair_bitcoin_addresses_and_balance_LATEST.tsv.gz

Get all unique addresses that are in both lists

Code:

Get list of balances, addresses and pubkeys

Code:

(the last for-loop is quick and dirty, slow and inefficient, but considering there's not that much data, I didn't bother improving it)

I like simple (Linux) commands that process a lot of data. A console is much more powerful than a GUI.
I've posted them in various topics, but from now on will collect them here. Use them at your own risk.

Warning
Don't just copy paste anything you find online into a console! Try to understand it first.
