Bitcoin : how to watch bitcoin transactions? looking for a friend..
I’d like to watch bitcoin transactions (incoming and outgoing) for a specific set of addresses, asynchronously. Blockcypher has a REST-API that works fine, as well as a [WebSocket API that doesn’t really work at all](https://github.com/blockcypher/node-client/issues/27) (see also [here](https://stackoverflow.com/questions/52275678/blockcypher-websocket-endpoint-not-working)).
I also created a [fiddle](http://jsfiddle.net/zaj6xL0y/3/). The only events that work are `ping` and `unconfirmed-tx`.
Is there any other event-based API that actually works, or do I really have to run my own full node?
PS – Go ahead and abuse my blockcypher API key 😉
The reason I included it is, because without the key not even the `unconfirmed-tx` event works. Also it’s a free-tier key, so you won’t be able to do anything fancy with it. 🙂
Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority.
