# Node API

Blockchain nodes are network stakeholders. Their devices are authorized to keep track of the distributed ledger and serve as communication hubs for various network tasks.

The primary job of a blockchain node is to confirm the legality of each subsequent batch of network transactions known as blocks.

Nodes do the following:

* Determine whether or not a transaction block is legitimate and accept or reject it.
* Save and store transaction blocks (blockchain transaction history).
* Broadcast the transaction history and disseminate it to other nodes that may need to synchronize with a blockchain.

On [whattofarm.io](http://whattofarm.io/), you can easily see that our nodes are faster than public ones.
