Does blockchain use websocket?

Question

Im programming an application for sharding on a p2p network but p2p networks have some serious problems like forwarding port , static ips and these things get a lot of time for me and it can be so bad for marketing and users. After all i wanna use smart contract on a blockchain to pay for it. Does blockchain use websocket for transfer blocks and data and give miners blocks ?

Answer 1

No blockchain's nodes relay transactions and blocks to their neighbours node after that they participate in the validation process. Ordinary users use wallets which connect to a node, this communication can base on socket or rest api
