Nodes are essentially the backbone of any blockchain system. Within these is where the blockchain’s data is stored, and they can be run on both commercial servers or the average user computer.
All blockchain nodes are connected to each other and constantly exchange the latest data with each other to keep the network “updated.” Data is hence stored, spread, and preserved within the blockchain, with nodes that contain a full copy of the transaction history of the blockchain called “full nodes.”
The fast growth of the Ethereum network has now catapulted to the biggest blockchain network, even though it was created over six years after Bitcoin. This can be attributed to the wide number of applications, instances, and products run on Ethereum compared to Bitcoin, which has seen less usage as a tech network and more as a digital asset.
Where are all the Bitcoin (nodes)?
2820 nodes, as per Bitnodes, as classified under “n.a. Meanwhile, the US leads in Bitcoin node adoption (in terms of ‘reachable’ nodes), with over 1847 nodes (16% of the network) situated in the country. Tech player Germany comes next on the list with 1712 nodes (15% of the network), with France coming in way below — 578 nodes (5% of the network).
The Ethereum network saw strong growth in the past week, with over 2,200 nodes added after Nov. 23. This coincides with the upcoming ETH 2.0 network launch, which sees Ethereum shift from its current proof of work consensus design to a proof of stake mechanism.
It goes live on Dec. 1, i.e. tomorrow, and is the first of a number of various phases. Ethereum would see a faster network, lower fees, and more scalability once ETH 2.0 is rolled out, a move that could take years before being completed in its entirety (the various phases will be continually deployed).
