How to listen to block events since block_subscribe is deprecated?

[dhruvja]

Problem

I want a listen to a stream of finalized blocks and the block_subscribe is the one i need. But seems like it is deprecated and i couldnt find any other alternative. There seems to be a workaround by passing a flag to the validator but i was wondering if I could listen to the events without running it since i would be needing it on mainnet.

Please tell me what i can use to listen to block events.

Hey there, this really isn't an issue or bug report for the code, so it doesn't belong here.

To answer your question, the argument - which isn't a workaround it's just an explicit flag to tell the node to use an unstable feature - can be passed to a local validator while you test locally. On your way up to higher clusters (devnet -> mainnet-beta), you'll need to find an RPC provider who offers BlockSubscribe.

Ok thanks i will keep a note of that. What is the right place to ask these types of questions?

Thanks for answering the question, i will try to find the rpc provider which offers that.
