Intro to Blockchain: How Protocols Work

·

This post marks the beginning of Part Two of a three-part series on blockchain technology. In Part One, I explored the historical context of blockchain, covering the evolution of both the modern internet and blockchain networks.

Part Two delves into the mechanics of blockchain technology, starting with this post on protocols, followed by posts on decentralized applications and initial coin offerings. Part Three will highlight promising investment opportunities in the sector.

Now, let’s dive into the core topic: why protocols matter.


Why Start with Protocols?

Protocols are the foundational innovation of blockchain technology. When Satoshi Nakamoto introduced Bitcoin in 2008, the real breakthrough was the underlying blockchain protocol that powered the network.

Before examining blockchain protocols, it’s essential to understand the protocols that enable the modern internet—after all, blockchain wouldn’t exist without them. If you’re already familiar with these, feel free to skip ahead!

FAQ

Q: Why are protocols crucial for blockchain?
A: They define the rules for secure, decentralized transactions, enabling trustless interactions.

Q: How do internet protocols relate to blockchain?
A: Blockchain builds on existing internet infrastructure (e.g., TCP/IP) but adds decentralization and cryptographic security.

Q: What’s the difference between Bitcoin’s protocol and Ethereum’s?
A: Bitcoin’s protocol focuses on peer-to-peer cash, while Ethereum supports programmable smart contracts.
