I Heard About Blockchain From a Research Paper

One of my seniors wrote a research paper on blockchain. I remember thinking "that sounds complicated and only for

crypto people."

I was wrong on both counts.

Blockchain is one of the most underrated concepts in computer science right now.And as CS students, we should be talking

about it more.

What Is Blockchain? The Actual Definition

A blockchain is a distributed, decentralized ledger that records transactions across a network of computers in a way that makes

them tamper-proof and transparent.

Breaking that down:

Distributed - No single server owns the data.Every node in the network holds a copy.

Decentralized - No central authority controls it.No bank. No government. No admin panel.

Ledger - It records transactions chronologically,

permanently, and publicly.

Tamper-proof — Once data is recorded in a block,altering it would require changing every

subsequent block across every node simultaneously.…
