Bitcoin is the decentralized peer-to-peer network mode of computers or nodes that run the Bitcoin software. Bitcoin nodes are pillars of the Bitcoin network. These nodes continuously monitor the blockchain. These nodes closely detect the history and chronology of transactions simply acting like a ledger. Closely observing the history makes them capable of stopping fraudulent transactions.
It also contributes to the security of the Bitcoin network through the consensus mechanism because nodes will break any consensus that will reject the transaction that breaks the Proof-of-Work mechanisms.
Besides this, nodes distribute and confirm transactions to the network. These transactions which show to miners are picked up by a mining pool that will add them to the blockchain’s universal ledger.
Besides confirming the transactions, miners will bundle pending transactions into the block. The confirmed block is distributed across the entire network and sent back to all nodes to confirm that the block is valid and follows all the network rules.
Different Types of Bitcoin Nodes
Once this process is confirmed, the new block is added to previous blocks, creating a blockchain. There are different types of blockchain nodes. They are differentiated on the basis of the tasks they perform. This division is done to speed up the validation process. The different nodes are listed below.
Full Nodes
Full nodes work by downloading the full history of transactions each block performs. It minutely observes that each block sticks to the Bitcoin rules. All the transactions made should prevent double speeding issues. It means that the blockchains made should not be spent somewhere else.
Also, one rule that they will adhere to is to check that each block creates only a limited number of Bitcoins which is 6.25 per block. Bitcoin full nodes are like servers. When nodes run they rely on the server to transmit transactions to the network. In Bitcoin terms, running own nodes means achieving control over money.
Light Nodes
Light nodes do not download the full data but only the essential information. They act as wallets. Light nodes download the information like the block header which contains the hash number, the mining time, and the previous unique identifying number of the previous transactions.
They are good for the nodes that do not have more storage capacity and are cost-efficient. Their task is to verify whether the transactions included were on Simplified Payment Verification. It does not validate all the transactions nor does it download the whole history of the block.
Mining Nodes
Mining Nodes are the nodes that store all the information about the blocks and also use the mining equipment. This is done to solve the mathematical computational problems and the purpose behind it was to mine Bitcoin. In this way, new blocks are generated.
Until 2010, any CPU was used as a miner node. Over time, as the network of Bitcoin increased, the CPU was no longer sufficient to mine the Bitcoin. So, the need for mining equipment arises for regulating the intensive energy.
Summary
In conclusion, Bitcoin nodes verify the transaction and maintain the ledger’s accuracy. Whenever the transaction is made on the blockchain with the help of these nodes, it is transmitted to all the nodes of the network. Hence, it ensures the proper functioning of the blockchain.
