The Ultimate Guide to Deciphering Blockchains vs Cryptocurrency

The purpose of this article is to untangle the confusion between blockchains vs cryptocurrency. I am going to spend quite a bit of time over the next week untangling the world of the blockchain and I will write what I have found. 

I described what is a blockchain in a previous article. 

I had researched and used blockchains a few years ago and I wanted to get updated on where the blockchain stands today. Boy, the blockchain world is confusing, to say the least. What was valid a few years ago has dramatically changed over the last few years. Blockchains have continued to morph and are starting to stabilize a bit. 

Here are some interesting statistics from Forbes. Cryptocurrencies reached $3 trillion dollars in 2021 from $800 billion in 2020. The two largest blockchains are BitCoin and Ethereum. The emergence of the Web 3.0, Metaverse, and Gamefi is going to drive the growth of the blockchain going forward. 

The Basics of Blockchain

Blockchain is a digital ledger where transactions are recorded in chronological order. Blockchain stores data in blocks, which are linked to each other. The size of the blocks is limited, which prevents the chain from being corrupted.

Blockchain provides an opportunity for people to send and receive money without any intermediary or third party involved. Blockchain technology is decentralized, which means that there is no central authority overseeing it – this makes it impossible for hackers to corrupt the system.

Mining is a process by which new transactions are added to the blockchain and verified by miners before they can be considered confirmed and processed by the network. Miners use their computers to solve complex mathematical puzzles and when they manage to do so, they get rewarded with bitcoins for their work.

Blockchain\’s Advantages and Disadvantages

Blockchain is a distributed database that is created by the network of nodes in the blockchain. The data in this database is public and can be accessed by anyone on the network. This data cannot be tampered with because it’s encrypted and every node has an updated copy of this information.

The blockchain is safe because it has a consensus mechanism to validate transactions. It also uses asymmetric cryptography to encrypt data in the database so that people can access it without compromising its security.

Centralized vs Decentralized Ledgers

A centralized ledger is a single shared database that is controlled by a single person or organization.

A decentralized ledger is a database that has been spread out over many different locations, and it can be accessed from anywhere.

The difference between the two types of ledgers is that centralized ledgers are more vulnerable to hacking and fraud since they are controlled by one person or organization, whereas decentralized ledgers are less prone to these risks because they have been distributed across many different locations.

The Basics of Cryptocurrency

A cryptocurrency is a form of digital currency that uses encryption to regulate the generation of units of currency and verify the transfer of funds.

Cryptocurrency is a digital currency that operates independently from any centralized bank or government. It relies on cryptography to secure transactions, control the creation of new coins, and validate transfers.

Some people see cryptocurrency as an investment opportunity while others see it as a means to make fast money. But for many people, it\’s just an interesting concept to keep up with in order to know what\’s going on in the world.

Cryptocurrency Advantages and Disadvantages

Cryptocurrency is a digital currency that can be transferred between individuals without the need for a central bank. Cryptocurrencies are not tied to any country or government and allow users to spend money anonymously.

The advantages of cryptocurrencies are that they are decentralized, more secure than most other forms of payment, and provide anonymity. The disadvantages of cryptocurrencies are that they can be expensive to use, there is no guarantee on the value of the currencies, and it is difficult to find people who accept them as payment.

Features of Blockchains vs Cryptocurrency

Blockchain is a technology that enables the creation of digital currencies and smart contracts. It uses cryptography to store data in an immutable way, which is then distributed across a network of computers. Blockchains are secure by design and are an example of a distributed ledger. The data on the blockchain cannot be hacked or tampered with, as it is encrypted.

Cryptocurrency is just one application of blockchain technology, but it is not the only one. Cryptocurrency can be used as digital money to buy goods and services online or in-person without having to go through banks or other third parties. Bitcoin was the first cryptocurrency ever created and it still remains the most popular one today, but there are many others like Ethereum, Litecoin, Monero, etc.

Web 3.0 Blockchain Technology Stack

The Web 3.0 blockchain technology stack is a concept that describes the potential future of the internet. The idea behind it is that the current web 2.0 model will eventually be replaced by a decentralized web 3.0 model that will be powered by blockchain technology.

Web 3.0 is considered to be the next generation of the internet and it will be built on blockchain technology, which means that data will not only be stored on centralized servers but also distributed across different nodes in a network so there won’t be any single point of failure or control over data and information stored on it. It also means that users would have full control over their data and who has access to it, because they would have their own private keys to their virtual assets instead of sharing them with other people.

The most comprehensive guides to the Web 3.0 Blockchain Technology Stack comes from from 2018 which still appears pretty accurate with some exceptions such as not all of the Web 3.0 technologies exist anymore but most of them still do. 


Features of the Web 3.0 Blockchain Technology Stack

The Web 3.0 Blockchain technology stack is a system for developers to work with digital assets and know that their code will be secure. It\’s a new take on the old web 2.0 that many people are familiar with, but this version has much more security and flexibility in its design.


In this article, I started to untangle the world of blockchains vs cryptocurrencies. I reviewed the blockchain, features of the blockchain, how it differs from cryptocurrencies, and the applications of Web 3.0.
