Node

A node is a server that is connected to other nodes that form the blockchain network. The server runs the Tezos specific software that has two main responsibilities:

  • Handle the communication with other nodes using the gossip protocol1. Nodes exchange all the time information with each other, such as updating about new operations and blocks.
  • Keep up-to-date the current context of the node, by applying all operations from the block to the local state.

Overview of Protocols 📑

/protocols

You can query the different protocols the node supports. You can do it with the following command from your terminal:

/chains/main/blocks/head

We are interested in identifying the current protocol the node is running. This call is one of the most important ones in getting the current state of the blockchain:

curl https://mainnet-tezos.giganode.io/chains/main/blocks/head

To further investigate the protocol PsCARTHAGazKbHtnKfLzQg3kms52kSRpgnDY982a9oYsSXRLQEb, we query for that identifier:

Chef's note (clippy)

We have organized for you all RPC calls of this wiki in a Postman collection.

  1. Interestingly this protocol is also called epidemic protocol, because the way peer-to-peer communication is established mimics how a biological virus spreads.↩
