/What are nodes? #Crypto #Blockchain #Web3

Blockchains consist of numerous blocks of data. This data is stored on nodes, which can be compared to small servers.

Nodes are the framework of a blockchain. Nodes store, spread and preserve blockchain data. On a blockchain all nodes are connected to each other and they continuously exchange the newest info on the blockchain with each other. Ensuring all nodes are promptly updated.

Now, nodes can be any kind of device; computers, laptops or servers.

/Functions of nodes - nodes broadcast info of the block to all nodes across the network when a miner adds a new block of transactions to the blockchain. - nodes accept or decline the block dependent upon validity of signature and transactions.

- nodes save and store new blocks accepted on top of the other blocks already stored.

/Different types of nodes 1. Full nodes - support & provide security to the network. - maintain the consensus between other nodes/ensure verification of data and store a copy on the blockchain.

2. Lightweight nodes - establish connections/links between users outside blockchain. - users in network, who need to connect to a full node to be able to synchronise with the current version of the network to be able to participate.

3. Miner's nodes - These apply to cryptos such as $BTC as they operate on a PoW consensus; once nodes validate a transaction, its presented in a pending form until a specialised node known as a miner(s) picks up the transactions.

4. Listening nodes - Also referred to as supernodes are publicly visible & accessible full nodes. - Function as communication bridges by providing blockchain data to other nodes.

/Nodes for passive income Nodes have become increasingly popular as a source of passive income. Nodes can create a great source of passive income. However, even though they are high reward, they're also high risk.

2 projects for nodes passive income 1. Strong Block Current $STRONG price - $9.79 (taken a big hit due to current market climate; ATH of ~ $3.1k) Amount to create a node: 10 $STRONG Daily reward: 0.093 $STRONG strongblock.com/index.html

⬆️ This could potentially be a great investment as the entry cost is low & price is bound to increase again.

2. Vapor Nodes Current $VPND price - $0.003197 Amount to create a node: 15k $VPND Daily reward: 1% ROI vapornodes.finance/

Takeaways: - nodes store, save & preserve blockchain data. - nodes broadcast data across the network. - nodes can be used for passive income.
