Bitcoin Forum

Hi,

I need to supervise some bitcoin addresses and I need to launch a custom event, maybe a custom sound for incoming transactions (unconfirmed sound and 2 confirmations sound) or sending an email.

I'm thinking about using Bitcore, but 8 GB RAM and more than 200 GB HDD for the blockchain doesn't look like a cheap way to go for such a simple task...a friend of mine suggested me to use electrum, but I'm not sure where to start or if it's possible to use electrum for such a thing. A VPS with 8 GB RAM and 200 GB of HDD is about 50$-140$ USD, and that's just way too much...


I'd really appreciate your advice and suggestions about this little project.

Thanks a lot

Presuming you meant Bitcoin Core, and not bitcore which is something different, you can always enable pruning to cut the block chain storage size down.  (And btw, I've seen a vps similar to what you mentioned for less than $100/year.  But $50-140/month is way too much.)

I meant Bitcore, not bitcoin core. It has an integrated API to check an address and all that stuff.

So, I'll keep checking transactions on supervised accounts like from 3 months from now? Can I use Bitcoin core with custom notifications? is it straightforward?
Bitcore is nice because of it's API, but maybe bitcoin core doesn't need so much coding in orden to make those custom notifications

You simply want to check addresses and see the coming transactions ? If it's the case then you could simply use https://www.blockonomics.co/views/wallet-watcher.html?next=%2Fblockonomics instead of buying a VPS which may cost you a lot of money. (there is an API too)

Ok, never mind then. I had assumed you meant Bitcoin Core since it was in this section on bitcointalk.  ;-)

Anyway, I am not sure if you can run Bitcore with pruned mode or not to save disk space.

Omegastarscream: blockonomics.co won't let me create custom notifications. It comes with http push and email notifications but I need to develop my own notifications

Have you tried using blocktrail's web hook (https://www.blocktrail.com/dev/signup) notifications? It's insanely easy to setup, even has a UI. Fill out a form and then if you want provide a callback URL to run a url or fire off some code on notification.

Or you could even subscribe to a websocket like blockchain.info's to monitor for transactions on the network without having to run a node. Their websocket API doesn't require an API key.

In fact their API provides http callbacks which you can easily you to develop your own notifications https://www.blockonomics.co/views/api.html#paymentnotify

That's a great way to get things going, dude! thanks a lot

BTW, I might use BlockCypher, they look pretty professional and got tons of tools to work with.

I'm gonna take a look at it. But as far as I saw in 2 minutes, looks pretty similar to the other two options
