Wow Ethtective is very cool ! Thank you

With txflow you can add successively different addresses and it should add links if it exists. If there is no link you should see two separate flows. I'll see what I can do about it

I'm not sure yet how to do the index part. If I can use an external one like electrum's index (because I have a node running electrum) but I don't know if it can help. Maybe I can use an external tool to index it myself but that would require extra space :/
I'll probably make it open source yeah

.

The interface is generated by a browser code, the rendering has nothing to do with the hosting plan (unless you take into account the time to serve the script to the browser).
I'm using a library (react flow) which ... was maybe not really made to be stressed with big transactions.
I'll probably optimize the interface by, for exemple, not rendering the input/output addresses of a transaction if it has more than x input/output, and add an option to expand it at will.

And sorry for the missing feature, I do it after work when I'm bored ahah.

I'm glad you liked it


Sorry you didn't have a good experience :/ Try with small transactions first and see what are your limits. I'll try to improve the performances :p

Hello guys !

Thank you all for your responses.

SO, I'm a bit embarrassed, the app was not working because I forgot my cors extension ^^'
blockchain.info has a ?cors=true option on it's API routes but not on /latestblock ( I suppose to avoid spams) so I made a little backend that query the api and cache the response. The address API route is still called via the browser so every user will have it's own limit rates.

I bought a domain so it's a bit cooler (www.txflow.io).


Yeah, I saw it once existed but I think they removed the feature. What a shame. So I did it myself ^^


You are already able to zoom, you should be able to try it out now



If I make a backend I will have to because it's not free to store and index a 500g+ blockchain.
I run my own node with lnd and stuff like that. Maybe I'll make something that reads directly the chain on people's nodes. You would have the "demo" on my domain, and you could still run a local version that reads YOUR chain.

What happens exactly ? Does it freeze or does the API reject your call ?
The exemple address has another transaction with a lot of inputs, since I render a node for every input address, that might cause your the app to freeze (I should at least put a warning). It works for me tho, here's what I get :


Did you try with any other address ?


I considered the question. I just wanted to make a PoC here, using an external API.
I have different ideas for the backend and but I want something easy to deploy for anyone on their own node (so they could read their own chain) if they want (and a demo saas version).
I'll post updates here


It's actually implemented. The '+' button in an addres loads all of it's transactions and the target addresses. You can dig in the direction you want (until you have a big transaction that crashes the app lol)

Hello,

I though it would be cool to visualize the bitcoin transactions. Blockchain explorers are practical, but they lack, in my opinion, graphical representation.
It might be nice for educational purposes as well.

I made it in JS so it can be accessed from the web. I'm currently using blockchain.info api, and users will subject to api rate limitations (that might cause CORS issues).
Maybe I'll make something to talk directly to your node with RPC so I can use extended public keys to derivate addresses without the risk of exposing it (and read data directly, without limitations). (I'm thinking about the umbrel app store for exemple)
I also use their websocket api to live update the transactions.

Here's an exemple of a an address with recent transaction, try it out

(Edit) or here's a preview


It's still WIP, some features are missing, when you open big addresses it crashes, api limitations are annoying (use a vpn). But I'd like your feedbacks. What do you think about it ?

I think I would take celerity (299792458 sats), because I love light and no one did it yet. But since it's too expensive atm, someone else will probably do it before me ahah

Hello
This is an old topic but I just found it on google because I was looking for a solution to this problem.
There is this site, blockchair.com that provide various filters to explore the chain.

https://blockchair.com/bitcoin/addresses?q=balance(314159265)#

Here is an exemple where you search for all addresses with a pi balance (in satoshi).
Hope it helps !

Have a nice day.
