Need advice on a web project (NODE/JS/PHP)

[jeezy]

Hey guys,

I'm currently planning a new web project and I'm not quiet sure how other sites handle this:

1) Scan the blockchain for transaction of certain addresses, save transaction to a DB
2) Handle found transactions one by one
3) Feed the web page with handled transaction data

My current thinking is this:

1) Develop a demon that subscribes to blockchain.info's websocket and scan for certain transactions
2) That's easy
3) Let the client poll the server every X seconds or only on refresh

The problems:

1) PHP or NODE.JS? Are there working libs for this? How do other sites do this?
3) What would you suggest? AJAX? Poll or push? Websocket server?

Cheers,
jeezy

You could have a local block explorer that you could make calls to with php... save to the db.. then use a websocket server to keep the website live.

That would be my approach.

Yeah, I guess the easies and probably most performant way would be to have a local bitcoind running on the server and make JSON calls to it. Since the transactions / addresses can all go into one wallet it would probably be the best option.

Only downside to this is that I need a lot of space on the VPS which will be expensive, since there is no bitcoind thin client, like an electrumd would be the optimal solution for this I guess.

Is a 10gb vps expensive? I would be more worried about the iops you will make.
