The key feature that makes blockchain engineering unique, and partially of why cryptocurrency has been sol revolutionary, is decentralization. Bitcoin and most early cryptocurrencies aren ’ deoxythymidine monophosphate controlled by a cardinal server or group of servers. rather, the network functions in a peer-to-peer ( P2P ) manner. People interact with each other directly quite than through a third-party mediator, thanks to network nodes .

How Do Blockchain Nodes Work?
For decentralization to work, there has to be a way for the network to maintain its integrity. Everyone has to be assured that all transactions are valid and that no matchless on the network is cheating by duplicate spend or reversing transactions .
The action of everyone on the network agreeing that transactions are valid in the absence of a central authority is known as “ achieving consensus. ” It is the network nodes that achieve this consensus among users, helping to make the blockchain guarantee .
consensus refers to the rules by which a blockchain network operates and confirms the robustness of data written in blocks. Confirming this information can be complicated with big networks involving large numbers of people, hence the motivation for a consensus algorithm .
The original consensus algorithm is Bitcoin ’ s proof-of-work ( PoW ) algorithm. Proof-of-Stake ( PoS ) is another popular consensus algorithm that works slightly differently but seeks to achieve the same goal. many DeFi protocols use PoS. Both algorithms trust on entire nodes for the validation of transactions and enforcement of network rules .
For the sake of ease, in this article we will assume that person is matter to in learning about Bitcoin nodes that run on PoW .
Anyone can download the entire Bitcoin blockchain and validate blocks. This increases both the security and the decentralization of the network, as more copies of the ledger come into universe and can be referenced by others. Bitcoin nodes can be run by anyone in the populace with the proper hardware and an internet connection .
7 Types of Blockchain Nodes
To recap : A node is one computer in a network of many that follows rules and shares information .
The term “ node ” is sometimes used interchangeably with the term “ full node, ” but they are not the same. A “ full node ” is a calculator in the Bitcoin network that stores and synchronizes a copy of the Bitcoin net ’ sulfur stallion blockchain history .
Full nodes are authoritative for respective reasons, not the least of which being that they vote on proposed changes to the network. When more than 51 % of full nodes don ’ t agree on a proposal, it gets skipped. sometimes this leads to a hard crotch, as was the case in 2017 with the Bitcoin Cash branch .

While there are several types of wide nodes, there are besides lightweight nodes. Below, we ’ ll highlight both lightweight and wax nodes .
1. Light Nodes
Lightweight nodes or “ light nodes ” do not hold full copies of the blockchain. Light nodes entirely download blockheaders, saving users meaning download time and storage quad. Nodes of this nature count on full nodes to officiate and are used for simplify requital confirmation ( SPV ) .
2. Archival Full Nodes
Most much, when person uses the term “ full node, ” they are referring to an archival wax node. This is the basal node type that forms the anchor of a blockchain network. Archival full nodes are servers that host the integral blockchain, with every single transaction recorded in their databases. The main task of these nodes is to validate blocks and maintain consensus .
Archival nodes can be broken down further into two subcategories : nodes that can add blocks to the chain and those that can not .
3. Pruned Full Nodes
A cut wax node is one that saves intemperate disk space for its users by “ pruning ” aged blocks in the blockchain. This type of node will first gear have to download the stallion blockchain from the begin. After that, it will begin deleting blocks beginning with the oldest and continue until the node entirely holds the most recent transactions up to a jell size limit. If a node operator were to set the size limit to 250 MB, then a pruned fully node would hold the most holocene 250 MB worth of transactions .
4. Mining Nodes
In crypto mining, miners are either full or clean nodes that try to prove they ’ ve completed the knead required to create a new stop. This is where the terminus “ proof-of-work ” comes from. To accomplish this job, miners have to either be an archival full node themselves, or get data from other nodes to learn the current status of the blockchain and how to work on finding the following block. ( Those who seek to run mining nodes might want to take into report crypto mining electricity costs. )
5. Authority Nodes
Authority nodes are used by consensus algorithm for networks that aren ’ t in full decentralized, including Delegated Proof of Stake and Proof of Authority. In these networks, either the development team will decide how many assurance nodes are needed and who will run them, or the community could vote for the decision. The undertaking of these nodes is the lapp as full nodes in other networks.
Masternodes can not add blocks to a blockchain. They only serve to validate and record transactions. Running a masternode can earn users a share of the network ’ sulfur rewards. Doing indeed requires first locking away a sealed measure of money in the form of the network ’ s native token. DASH is an exemplar of a network that uses masternodes .

7. Lightning Nodes
Lightning nodes don ’ deoxythymidine monophosphate quite fit the mold of any of the nodes discussed indeed far. The chief mind of a lightning node is to establish a association between users outside of the blockchain, enabling what are referred to as “ off-chain transactions. ”
This reduces the load on the network and allows for much faster and cheaper transactions. Bitcoin lightning transactions typically cost 10 or 20 satoshis, or the equivalent of a divide of a penny .
How to Set Up and Run a Full Node
Running a full blockchain node comes down to the play along :
• Choose a blockchain ( Bitcoin, for model )
• Acquire the hardware and/or software needed
• Start running the node
The first thing required for running any kind of lymph node is the necessary hardware. This often involves a little calculator like a Raspberry Pi. There are three different ways to run a full node. They include :
• Hosting a node in the cloud via Amazon Web Services or Google Cloud
• Running a node on your local device ( which requires a fortune of hard disk outer space and RAM )
• Using a “ node-in-a-box ” solution or building one from scribble .
After that, it ’ second just a count of maintaining and monitoring the node .
People might choose to run wide nodes for a variety of reasons, including increased privacy or a desire to support their network of choice. Lightweight nodes and wide nodes alike come with wallets that can be used for making cryptocurrency transactions. Full nodes provide greater privacy, as outside observers have a hard clock time distinguishing between transactions being processed by the node and transactions sent by the person running the node .
