How are you? Hope so everyone would be safe and sound just like me as I am also safe Alhamdulillah....

Today my topic discuss is about Bitcoin nodes and network topology. I am going to share in depth about my topic along with some of the practical examples so that it may be clear to understand to all of you.

Bitcoin nodes are most crucial part of the Bitcoin network because they are helpful in verifying and relaying transaction so it ensures the integrity and decentralization of blockchain. There are multiple types of nodes and each contains their unique roles and responsibilities.

Full Nodes

Full nodes store whole copy of the blockchain, which include verification of each and every transaction and block. They are the main part of the network which provides a secure and trustworthy way for validation of the blockchain.

As an example let's imagine;

Ali is a person who runs full node at his computer and he download whole blockchain and verify each and every transaction.He is showing his contribution to security and decentralization of network.

SPV (Simplified Payment Verification) Nodes

These are other type of nodes storing only block headers which verify blockchain integrity without any requirement to store every transaction. These nodes are lighter and more efficient and this us really best option for everyday use.

As an example;

Ali is running an SPV node at his mobile
phone so it is permitting him in receiving and sending bitcoins without storing them at whole blockchain.

Node Network Topology

Bitcoin is decentralized and peer-to-peer network in which nodes remain connected and communicated with each other.If I talk about topology then it is dynamic, with nodes continuously connecting and disconnecting.

As an example imagine that;

Ali has connected his full node to Ahmad SPV node and it is also connected to a mining pool full node. It creates a network of nodes used for verification and reliance of transactions.

Now here I am with network topology Practical example

Imagine that Ali wants to send 1 Bitcoin to Ahmad.First he creates a transaction and the he broadcast it to official network. His full nodes are used for verification of the transaction and relays it to nearby nodes which includes Ahmad SPV node. Ahmad nodes would verifie the transactions by using block headers and by updating his wallet. The transaction would be relayed after that to mining pool full node, and it includes it in block and would also add it to a blockchain.

Now in the above example you can see how nodes work with each other for verification and reliance of the transaction so it ensures the security and decentralization of the Bitcoin blockchain.

In summarized words Bitcoin nodes and network which enables high level of security and integrity for Blockchain and decentralized transactions. It is important to understand different types of nodes and their role which they play really helpful in appreciating complexity and smoothness of Bitcoin network.
