Blockchain technology is a type of decentralized and distributed technology used to store data and record transactions securely and transparently. The technology represents an improvement over traditional registry methods, and here are some key points:
1. **Chain of Blocks**: Data is stored in sequential blocks, where each block represents a set of transactions or data.
2. **Decentralized**: There is no central entity controlling the technology, but rather the data is distributed across many devices or computers (nodes).
3. **Security and non-tampering**: Once data is recorded in a block, it is difficult to modify or tamper with, which increases security and trust.
4. **Encryption technology**: It relies on encryption techniques to protect data.
5. **Multiple Applications**: The technology is used in a variety of applications beyond cryptocurrencies, such as supply chain tracking and voting systems.
In short, clustering is a way to maintain records that are tamper-proof and verifiable by everyone.
