 Traditionally, when you run an application be it a website or something that connects to a server you are interacting with a centralized entity. This is the opposite of what you may recall from our distributed blockchain example, in that the server is controlled and run by a single centralized group.
 
-Blockchains, as we saw, run on a network of independent nodes. In our previous example, each of the `Peers` was representative of an independent `node` operator. The term `node` typically refers to a single instance of a decentralized system, Peer A would be a `node`. This network, this combination of these nodes interacting with each other is what creates a blockchain. What makes these networks so potent, is that anybody can join. All anyone needs is a little bit a hardward and you can participate in securing a blockchain network. You could go to GitHub and start operating a node in a few seconds!

 In the traditional world applications are run by centralized entities and if that entity goes down or is malicious or decides that they want to shut off - they just can. They're the ones that control everything.
 
-Blockchains, by contrast, don't have this problem. If one node or one entity that runs several nodes goes down, since there are so many other independent nodes running, it doesn't matter, the blockchain and the system will persist so long as there is at least one node always running. Luckily for us, the most popular chains like Bitcoin and ethereum have thousands and thousands of nodes. Malicious nodes are kicked from the network, or even punished in some cases. Majority rules when it comes to the blockchain.

 This gives blockchains this incredibly potent immutability trait where nothing can be changed or corrupted so in essence we can think of a blockchain as a decentralized database.

 `Proof of Work` is known as a sybil resistance mechanism because it defines a way to figure out who is the block author or which node did the work to mine a block. Sybil resistance is a blockchain's ability to defend against users creating a large number of pseudo-anonymous identities to gain a disproportionately advantageous influence over said system.

 `Proof of Work` also serves as a means to determine who receives transaction fees as we discussed earlier. These transaction fees are paid by whomever initiates the transaction. In a Proof of Work system, every node is competing against eachother to solve the block problem first. The first node to solve the problem gets paid the transaction fees accumulated in the block they mine. In addition to this, miners are also paid a `block reward`, the `block reward` is given by the blockchain itself.

 The first feature is decentralization; smart contracts do not rely on any centralized intermediary. Instead, they run on a blockchain which is maintained by thousands of individuals known as node operators. It's the collective effort of these node operators running the smart contracts that make the network decentralized. This aspect will be discussed more in-depth later.
