Is there any chance to adjust this to do a local search in the full list of all funded address? That guarantees privacy.

1 - To achieve the same result as using sochain (or any other) API the file would have to be updated every 10minutes (1 update after each block), like you said.

That means running your own node and parsing all new blocks by yourself. That's not something I can do (yet).

it would take several minutes to download this csv file

I don't really mind waiting a few minutes for certain things. In fact, I often download 800 MB now just to check a few addresses. A better system would be to only download changes after the initial download, so it would be much faster.

I can get the balance of any address in just one or two seconds

When I tested your site with 30 addresses, I got only 9 results. It was fast, but incomplete. But what if you want to check 10 million addresses? Or even just 10 thousand? As far as I know, there isn't a single website that can do this, while there are already a lot of websites that tell you the balance of one (or a few) addresses.

I don't know if CSV is really the best file type to work with big data (which is what the blockchain is). I would have to study more about it.

When I do a local search to find matching addresses, it doesn't really matter much for the search time whether it's 1 or a million addresses. I'm pretty sure using a database would be much faster to get one address, but I don't know if it can beat the speed of searching a text-file for a million matches.

Maybe I could do something with SQL? Or change it to JSON format (which has a faster processing, I think). I will have to study more about it.

Let me know if I can help, just know I still know nothing about databases Tongue

I'm pretty sure most people who want to get balances of (say) a million addresses are trying to brute-force private keys. That means All Bitcoin addresses ever used to keep any private key that has ever been used. I know there are people who brute-force for instance brain wallets, but I don't know what they use to check the address history for many (millions of) addresses per second.

Why not just create watch address book in Electrum wallet and import all your wallet addresses?
Much better than trusting any website or explorer.

Because you will be trusting electrum servers. You are just trusting someone else.

You can do this with Bitcoin Core without this privacy problem.

Those addresses are obviously of the same person

Not all the information you send has to be yours, you can easily add some other read-only addresses to your list. Some fake information can improve your privacy (but it won't make it easier to see the total balance).
