I’ve previously given an example using Bitcoin – users are free to download the whole blockchain and validate blocks, thus increasing security, as more and more copies of the ledger are created and used for reference.

While consensus must be achieved by a certain type of nodes, the beauty of a P2P network is that anyone can become a full node and thus achieve higher levels of independence and decentralization.

No matter which one has been chosen for a coin, they both have a crucial factor in common – reliance on full nodes for enforcing of rules and validation of transactions. The differences between the two, I’ll cover later down below. The most common ones are Proof of Work (PoW) and Proof of Stake (PoS). This is where consensus algorithms come into play. As you can imagine, agreeing on something with a large number of people is bound to lead to complications. The rules by which a blockchain network operates and confirms the validity of information written in blocks and/or work performed is termed “consensus”.Īs we’ve already covered, cryptocurrencies operate on a decentralized P2P network. You might be wondering what that relates to in crypto terms. In the previous section, I mentioned consensus. The second type is a lightweight node – each user participating, who needs to connect to a full node in order to synchronize to the current state of the network and be able to participate. Full nodes which store a copy blockchain and thus guarantee the security and correctness of the data on the blockchain by validating data. Take Bitcoin for example – you have two types of nodes. As they’re all crucial to the security and integrity of the network, becoming a member of a certain crypto coin community is not only exciting but also a responsibility. In most networks, there are no dedicated servers, not one authority, but a consensus among users. It’s based on the principles of a P2P (Peer to Peer) network. There are different types, but each of them shares one specific characteristic – you’ll require specific hardware in order to host or simply connect to one.īlockchain technology is decentralized by nature – one of the key properties that made it so appealing to the wide public. In general, every participant in a coin’s network is a node. Let’s begin by explaining what a blockchain node is.
