What Is a Blockchain Node? 🌐🔗
A blockchain node is a computer that participates in a blockchain network by receiving, storing, and verifying blockchain data according to the network’s rules.
⚙️ How Does a Node Work?
1️⃣ Receives Data
Nodes receive transactions and blocks through the peer-to-peer network.
2️⃣ Verifies Transactions
The node checks whether transactions follow the protocol rules.
3️⃣ Verifies Blocks
It checks the block structure, transactions, cryptographic references, and other consensus requirements.
4️⃣ Stores Blockchain Data
Depending on the type of node, it may store a large portion or the entire blockchain history.
5️⃣ Shares Information
A node can relay valid transactions and blocks to other nodes.
6️⃣ Helps Maintain the Network
By independently verifying data, nodes help the network maintain a consistent state without relying on one central server.
🧠 Key Idea
A blockchain isn't running on one powerful computer.
It operates through a network of independent computers communicating and verifying information according to shared rules.
Node → Verify → Store → Share → Maintain the Network
That distributed structure is one of the foundations of blockchain technology.
