🏙️ Imagine a city without traffic lights, traffic rules, where everyone drives as they please. Chaos, accidents, nobody gets through. In the cryptocurrency world, where money "lives" in the digital space, order is also needed. And it is provided by protocols - invisible rules that determine how cryptocurrency works.

What is a protocol?

A protocol is a set of instructions that defines how network participants should interact with each other. It's like the "constitution" of cryptocurrency, setting the basic rules of the game.

What types of protocols are there?

Cryptocurrency protocols can be divided into several categories:

• Consensus Protocols: Determine how network participants agree on the state of the blockchain. Imagine you need to agree on where the library will be located in the city. The consensus protocol "chooses" the location where the library will be located, and all participants agree to this decision.
  • Proof-of-Work (PoW): The most popular protocol. Imagine that in order for a participant's "voice" to be counted, they need to solve a complex puzzle. The more effort they put in, the more "votes" they will have. This is how consensus is established.
  • Proof-of-Stake (PoS): Instead of solving puzzles, "votes" are given by participants who "stake" their money. The larger the "stake", the more "votes" the participant has.
• Smart Contract Protocols: Allow for the creation of automated contracts that are executed without human intervention. Imagine a ticket vending machine where you put in money and get a ticket. The smart contract works on a similar principle, automatically fulfilling the terms of the contract.
• Decentralized Finance (DeFi) Protocols: Allow building financial services without the involvement of traditional banks and institutions. Imagine you can take out a loan or invest in the stock market directly through the blockchain. DeFi makes this possible.
• NFT (Non-Fungible Token) Protocols: Allow creating digital assets with unique properties. Imagine a painting in a museum. NFT makes it a digital version that is also unique and unrepeatable.

Why do we need protocols?

Protocols ensure security, transparency, and trust in the cryptocurrency network. They guarantee that transactions will be executed correctly and money will not be stolen.

What tasks do protocols solve?

• Consensus: Consensus protocols help network participants agree on the state of the blockchain, which is essential for the security and integrity of the network.
• Security: Protocols ensure transaction security and protection against hacking.
• Decentralization: Protocols make cryptocurrency decentralized, i.e. not controlled by one organization.
• Transparency: Protocols ensure transparency of all transactions, allowing tracking the movement of money and verifying their authenticity.

Who can create protocols?

Protocols can be created by both individual developers and teams of developers working on open source code.

How to determine if a protocol is secure?

The security of a protocol depends on many factors. It is important to pay attention to the following points:

• Audit: The protocol should be audited by an independent auditor to identify vulnerabilities in the code.
• History: The protocol should have a good history without known hacks and vulnerabilities.
• Community: The protocol should have an active and professional community of developers and users.

Protocols play a key role in the operation of cryptocurrencies, providing security, transparency, and trust in the network. Understanding them helps you navigate the cryptocurrency world better and make more informed investment decisions.

Remember, protocols are the invisible but very important part of the cryptocurrency system. Studying them is the key to successful movement in this dynamic and promising world.
