Brief Background on Blockchain Technology
For those less familiar, blockchains are distributed ledgers that record transactions in an immutable, transparent way without needing central authorities. Data is stored in groups of blocks that link together to form a chain, giving the technology its name.
Some key properties that make blockchains invaluable across industries:
- Decentralization – No single entity controls the network
- Transparency – All participants have real-time visibility of transactions
- Security – Cryptography ensures integrity and prevents tampering
- Immutability – Transactions cannot be altered, only appended
Blockchains enable direct transactions between untrusted parties without intermediaries. This eliminates inefficiencies, delays, and costs posed by traditional transaction systems.
Popular blockchain platforms like Ethereum allow developers to build decentralized applications (dApps) that inherit the same useful properties. Smart contracts encode complex business logic and rules that execute automatically when conditions are met.
Common Use Cases
- Supply Chain – Track the origin and movement of goods in real-time
