Blockchain data download

[Rexall]

Hi All,

I'm looking for pre-parsed blockchain data downloads.  Ascii.  So I can use Awk, grep and sed. ;^)
I found http://addresses.loyce.club.
Is this the best/a really good site or are there other repositories to draw from?

I would like to analyze zombie addresses with a balance, sometimes called dormant addresses.
I did see some python code that might be helpful.

Any suggestions?
Thanks.

Here are Some popular sites where you can download blockchain data from

• Bitcoin Core
• Blockchair

You can make use of an external software to parse it
Do you intend on running a node?

Here are Some popular sites where you can download blockchain data from

• Bitcoin Core

That is a page to Download Bitcoin Core wallet software. It's not a link to download Bitcoin blockchain data.

After you download the software, you will have two options to run your wallet, prune node or full node.
Both will download all blockchain data but prune node will delete data from past blocks that exceed the storage you set. Full node will store all blockchain data on your device.

• Blockchair

At blockchair.com you can download blockchain data at https://blockchair.com/dumps#database

That is the list maintained by LoyceV, link to profile: http://bitcointalk.org/index.php?action=profile;u=459836
The user is one of the most prominent members here in the forum with lots of good contributions.

As for the list's safety and data integrity, there's no way to verify, but refer to LoyceV's trust rating which is in very high positive standing.

The site above collects data from Blockchair Database Dumps. You can do this by purchasing API packages form any block explorer and then using Python to arrange them or do whatever you want.

Bitcoin block data (728 GB): inputs, outputs and transactions
You can trust the data that comes from this site, but if you do not trust it or Blockchair, it is better to run a full node.

Wow! Thanks to everyone for responding so quickly.
Yes, I do plan to run my own node, but it seems like parsing my own blockchain data may be not the best way to go.
I've got lots to work with now.

Running a full node will help you a lot in privacy because you can use Tor and broadcast your transaction with your own full node.

Did you read this guide to run a full node with cheap cost?
[Guide] How to run a Bitcoin Core full node for under 50 bucks!

I've got lots to work with now.

Running a full node can help the Bitcoin network too because full nodes validate Bitcoin blocks. When you run a full node, you are contributing to Bitcoin network.
Live nodes: https://bitnodes.io/

To use blockchain data, you will have to do more tasks by yourself and sure it will take more time and efforts from you.

I figure you want to be able to list addresses such as those that figure on this site, that already list the top balance dormant addresses (in out terms, disregarding ins) for periods of time ranging from 1 to 9 years.

As an alternative to having to download stuff, I took a brief look to see if it was feasible to do using dune.com. There is a table there with bitcoin balance (balances_bitcoin.satoshi_day), and there are tables with inputs, outputs and TXs, so theoretically, using these tables, and filtering the joins with date intervals and minimum balance values, one should be able to derive the information on the platform.

I gave it a quick go, but despite using up some credits to use the middle sized engine, I kept on getting timeouts for a relatively simple query that tried to obtain all TXs with a current balance of over 2K BTCs and no outputs to date. It could be an alternative to explore further though, in case you don’t eventually create a custom solution on your own environment.

I like those

I don't think this is the data you're looking for. It doesn't have any information on when addresses were funded. You'll need the full blockdata.

Not practical option when they limit download speed at only 10 kB/s.

Actually, it's 100 kB/s nowadays, so it "only" takes you 3 months to download
That's why I've created a mirror:

Related topics
Bitcoin block data available in CSV format
List of all Bitcoin addresses with a balance
List of all Bitcoin addresses ever used
[~500 GB] Bitcoin block data: inputs, outputs and transactions
[800 GB] Ethereum data

This (donated) server burns through rougly 12 TB of bandwidth per month.

[LoyceV]

Shouldn't OP get what he wants by performing union between data on that link and http://alladdresses.loyce.club/ ?

Interesting idea, but I don't think so. That would put all funded addresses in chronological order of the first received transaction. That doesn't mean they're "dormant", they could have received more recent transactions too.

I can think of a combination of "comm" and "sort" to combine those 2 lists. If there's any interest, I'll do it, but only once. With limited RAM and HDD, I expect it to take a few hours to sort this long list.

Correct.  I should have said something like address, input, output, net and final TX date.
I'm actually trying to find a way to get similar output to this defunct google code project:
https://docs.google.com/spreadsheets/d/1xTROekDerP1TPOB3SOD_1bbQr580BPqbhF3YHdO96pw/edit?pli=1#gid=189298223
But that method looks useless without 2TB of memory.
 
So I was thinking to manipulate previously dumped data.

Thanks for mentioning dune.  I have a login there but thought it was just ETH.  I will have another look.

Aha... good stuff!  Thanks
