Differences Between A Full Node And Light Client In Bitcoin Blockchain Mining


This is The Difference Between a Node and a Light Client

If you are a newcomer to the Bitcoin world, you might know that it is possible to download the entire blockchain. In this way, you will have registered all the transactions that took place on the Bitcoin ledger. But clearly, this is a very time-consuming task and it may take a lot of space. However, there is a very simple way to improve this process.

Being a node means that you are connected to the blockchain network and you are able to control and enforce the rules of the blockchain. Full nodes help the network in many ways, making the blockchain much more secure.

But as mentioned before, being a full node requires a lot of space and it is a time-consuming task. This is why, there are also lightweight nodes. These are light clients that are referencing a trusted full node’s copy of the blockchain.

In this way, it is possible to transact without having to download the entire copy of the blockchain. Currently, the Bitcoin blockchain is a 27 GB ledger that must be synchronized with the network’s nodes, which are more than 6000.

Light nodes use a different method to verify transactions. Full nodes are the best option for services providers, miners and developers. Users like we are are going to use light clients that use the simplified payment verification method (SPV) allowing a node to verify whether a transaction has been included in a block or not. And everything without having to download the entire blockchain.

For example, mobile wallets use this method since they are not able to download the full blockchain on smartphones.

As mentioned before, light clients will allow users to interact with the Bitcoin blockchain and to make and confirm transactions in a simple manner. It is important to mention that full nodes are trustless, meaning that they would not accept a transaction that violates the consensus rules.

Light clients are the best option if you are not a miner or a services provider. If you believe that you have the necessary space and experience to run a full node, then, you can start to do it since full nodes are the backbone of the Bitcoin network. Full nodes route mining, provide wallet services and verify transactions. Light clients provide accessibility and ease of use.
