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. Computationally near impossible.…
