There are a few ways that blockchain nodes can find each other. One way is through the use of a discovery protocol, which is a mechanism that allows nodes to find and connect to each other. Another way is through the use of a bootstrap node, which is a node that is manually configured to connect to other nodes in the network.

Q: How do blockchain nodes connect to each other?
A: Blockchain nodes connect to each other through a process of discovery. Nodes broadcast their presence on the network and listen for other nodes. When a node hears about another node, it will try to connect to it.
Q: How do crypto nodes find each other?
A: There is no one answer to this question as there are a variety of mechanisms that can be used for crypto nodes to find each other. Some of the more common methods include using a central directory server, using a distributed hash table (DHT), or using a peer-to-peer (P2P) network.
Q: How do nodes communicate with each other Bitcoin?
A: Nodes communicate with each other by sending and receiving messages through the network. The messages include information about transactions, blocks, and other events that have occurred on the network.
Q: How does Bitcoin node discovery work?
A: Bitcoin nodes use a mechanism called “address broadcast” to discover each other. When a node starts up, it broadcasts a special message called an “address” message to the network. This message contains the node’s IP address and port number. Other nodes receiving this message add the sender’s IP address and port to their list of known nodes.
