In the era of the digital economy, a technology is quietly transforming the way multiple industries such as finance, healthcare, and logistics operate — and that is blockchain. Although many people have heard of this term, few truly understand it. Today, we will provide a simple and clear explanation of this world-changing technology.
What exactly is blockchain?
In simple terms, blockchain is a distributed ledger technology. Imagine a ledger that is not maintained by a single institution but is stored simultaneously by thousands of computers. Each transaction record is encrypted and stored, forming an immutable chain-like structure.
The brilliance of this design lies in — no one can modify the data alone. Because once a piece of data is changed, the cryptographic fingerprint of the entire chain will alter, and other nodes will immediately detect the anomaly. This is why blockchain has an inherent tamper-proof feature.
From academic concept to practical application
The story of blockchain begins in the 20th century.
