Each transaction is encoded with a cryptographic hash, uniquely identifying it within the chain. This makes it tamper-proof and secure against unauthorized modifications.
Transaction Process Explained
The transaction process in blockchain technology involves several steps:
- A user initiates a transaction, specifying the details.
- The transaction is broadcasted to a network of nodes for verification.
- Nodes validate the transaction through consensus mechanisms, ensuring all criteria are met.
- Once approved, the transaction is combined with others to form a new block.
- This block is added to the existing blockchain, updating the public ledger.
This systematic approach demonstrates how blockchain technology works, reinforcing trust and transparency.
Importance of Nodes
Nodes are vital as both validators and record-keepers in the decentralized network. They ensure valid transactions are accurately recorded and prevent fraudulent activities through consensus. A network of distributed nodes increases resilience, making the blockchain robust against failures or attacks.
