The following steps will add a new node named eth101-a-node02 to the Ethereum network eth101-a of user A.
Click the Add Node button in eth101-a, fill in the "Node Name" as eth101-a-node02, and click the Create button.
Wait for the new node to be created. The new node defaults to "non-validator". If you need to change to "validator", you can initiate "voting" in the Ethereum network.
In Istanbul Byzantine Fault Tolerant (IBFT) based consensus, we call miner node the “Validator”. A minter is responsible for validating transactions and bundling transactions into a block just like an Ethereum miner. The boxer icon shown following is to indicate this node is validator/miner.
The node added by “Add Node” is the client node, also known as the “non-validator node”, which is not responsible for mining, but will synchronize the data on the blockchain. In Istanbul Byzantine Fault Tolerant (IBFT) consensus, to change the client node to a validator node, it need more than 1/2 of validators’ approvements.
