How to connect to a public node through json RPC?

0

I found a list of public bitcoin nodes here. I am using a php library. How can I connect to these nodes via JSON RPC? Is it safe to connect to public nodes? What should I give as username and password?

I had tried a bitcoin node on my ec2 instance. It is taking too long to sync and blockchain size is also increasing. I want to communicate with bitcoin network without running a bitcoin daemon.

Not all nodes will have the JSON-RPC enabled, and especially without private credentials. You will probably find a block explorer API much more accessible, because they are built to handle public traffic. There are many blockchain explorers online that have public apis, they are easy to find.

1You can run an SPV node (light node) – JBaczuk – 2018-12-21T05:48:26.393

1You'd be very foolish to trust a random node in the network to make private keys for you. – Anonymous – 2019-01-20T06:14:13.350
