Title: Need advice on a web project (NODE/JS/PHP) Post by: jeezy on August 28, 2013, 05:13:50 PM 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 Title: Re: Need advice on a web project (NODE/JS/PHP) Post by: jeezy on August 29, 2013, 07:27:24 AM 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.
