Starting Your Token Journey


Blockchains, crypto exchange platforms and other key concepts

A beginners guide to the key concepts underpinning the token movement.

Token Takeaways

✨ Blockchains are decentralised networks that host cryptocurrency tokens.

✨ Blockchain technology is powerful as it is censorship resistant and immutable, and it offers people a way to move tokens anywhere at any time without relying on an intermediary. 

Crypto exchange platforms allow users to buy, sell, and trade various cryptocurrencies.

The token movement’s rapid growth has increased interest in cryptocurrency tokens and crypto exchange platforms. With every new market cycle, the space attracts new adopters to tokens like BTC, ETH, and SOL. But while tokens have grown in popularity, the technology powering them doesn’t always get as much attention. Tokens could profoundly change the world around us, and they offer huge promise thanks to blockchain technology. Blockchains host tokens, which are the essence of what makes them so powerful. So, we felt it would be apt to put together a guide covering all the essential blockchain basics. Read on to learn more.

Blockchain technology explained 🧠

So, what is a blockchain? 

A blockchain is a distributed digital ledger that stores data. Blockchains share some similarities with databases, but they offer many benefits that databases cannot. 

Blockchains live on the Internet; networks of nodes based all over the world are responsible for maintaining them. These nodes are responsible for keeping a record of all activity on a blockchain network, which means the blockchain’s transaction history can always be verified. 

Blockchains use cryptography to secure data and process transactions. The term “blockchain” comes from the way the network processes transactions—transactions are grouped together in “blocks,” and miners or validators verify new blocks before they join the “chain.” Once the chain adds a new block, the transactions appear on the public ledger. 

By far, the most popular use case for blockchain technology is facilitating cryptocurrency transactions. Bitcoin was the world’s first blockchain, and it’s used to transfer and store the BTC token. But as the technology has grown, many other blockchains have emerged, hosting a myriad of new tokens and cryptocurrency applications.  

Why are blockchains useful? 🤔

Blockchain technology has many benefits. By powering cryptocurrency tokens, blockchains offer ways to store, exchange, and generate value that were never previously possible. 

The most ardent token enthusiasts describe blockchain as a technological breakthrough that could disrupt entire industries and transform how our society functions.

Blockchains like Bitcoin have several powerful properties: 

Censorship resistance—As the nodes supporting blockchains are based worldwide, blockchains are very difficult to censor. In other words, they are censorship-resistant.

Immutability—Thanks to cryptography, blockchain transactions are immutable. This means that a token transfer is permanent once the transaction is confirmed. 

Borderlessness—As blockchains live on the Internet, they are borderless. This means blockchain users can send tokens around the world at any time without needing a wire transfer or bank service. 

Permissionlessness—Anyone with an Internet connection can join a blockchain network, create a wallet, and make a transaction. They don’t need to ask permission from anyone; the blockchain is permissionless. 

Trustlessness—At their core, blockchains remove the need to trust intermediaries. Anyone can transfer without relying on a trusted service, as the blockchain is trustless.

These properties combined closely relate to blockchain technology’s core tenet: decentralisation

Blockchains offer censorship resistance, immutability, borderlessness, permissionlessness, and trustlessness because they are decentralised networks. The blockchain and token movement aims to take power away from centralised entities and give it to individuals so they can independently support the causes they believe in and control their assets. 

The different types of blockchain 👀

Bitcoin was the first blockchain and the best crypto to invest in if we could travel back to those early days. Today, there are around 200 million Bitcoin wallets worldwide and Bitcoin accounts for approximately 47% of the space’s value. The Bitcoin network has thrived thanks to its simplicity; it has only undergone a few changes since it launched, and its primary function is storing and exchanging BTC tokens.

The advent of smart contracts in the blockchain ecosystem

Behind Bitcoin, Ethereum is the world’s second-biggest blockchain, representing around 19% of the global token market capitalisation. Ethereum differs from Bitcoin as it runs smart contracts, automated programs that allow for complex functions on a blockchain. Smart contracts power many different kinds of applications on Ethereum, fulfilling the network’s goal to create a decentralised version of the Internet.

Bitcoin and Ethereum both found huge success in their early years. Since Ethereum’s rise, many other smart contract platforms, such as Solana and Avalanche, have emerged, offering similar use cases and slight technological differences.

What are crypto exchange platforms?

Crypto exchanges or crypto exchange platforms are online platforms where users can buy, sell, and trade various cryptocurrencies. They provide a marketplace where users can trade cryptocurrencies for other digital currencies or fiat currencies like USD, EUR, etc.

There are different types, and finding the best crypto exchange depends on user preferences:

Centralised Exchanges (CEX)—These are crypto exchange platforms operated by a company or organisation that maintains control over users' funds. Users create accounts and deposit their funds into wallets managed by the exchange. Examples include Binance, Coinbase, and Kraken.

Decentralised Exchanges (DEX)—DEX operates without a central authority. They facilitate peer-to-peer trading directly between users, allowing them to retain control of their funds through their wallets. DEX platforms use smart contracts and blockchain technology to execute trades.

Hybrid Exchanges—These exchanges combine features of both centralised and decentralised platforms to offer various services. They might have a centralised order book but allow for decentralised settlement, or vice versa.

Crypto exchange platforms play a significant role in the cryptocurrency ecosystem by providing liquidity, enabling price discovery, and serving as a gateway for users to access different digital assets. However, users must do their homework and choose the best crypto coin exchange based on their investment strategies, whether they aim for short-term trading, long-term investment, or accessing specific tokens for various blockchain-based projects.

Proof-of-Work and Proof-of-Stake 🥩

As blockchains are decentralised, they rely on users to collectively verify transactions and achieve consensus on network activity. 

Most blockchains use one of two mechanisms to reach consensus: Proof-of-Work and Proof-of-Stake.

In Proof-of-Work networks, network participants called miners use hardware to solve complex mathematical problems to verify transactions. Miners put in “work” to compete to solve the problems and earn a reward whenever they add a new block to the chain. Bitcoin uses a Proof-of-Work algorithm. 

In Proof-of-Stake networks, validators put up a “stake” of the blockchain’s native token and verify transactions. Validators typically earn a yield in the blockchain’s token as a reward for securing the network. Ethereum switched from Proof-of-Work to Proof-of-Stake in September 2022, while most newer blockchains use Proof-of-Stake. 

Layer 1 and Layer 2

Blockchains can also be defined as “Layer 1” or “Layer 2” networks. 

Layer 1 blockchains are base layer networks where transactions settle, and new blocks join the chain. Layer 1 blockchains use a native token, and they must be secure, decentralised, and scalable. The term “Layer 1” is most frequently used to describe smart contract blockchains like Ethereum and Solana today.

Layer 2 blockchains are networks that live on top of a Layer 1 base chain. They help Layer 1 blockchains scale, offering benefits like higher transaction speeds and lower costs by reducing congestion on the base network. Layer 2 blockchains inherit the security of a Layer 1 blockchain, but they often have their own native tokens for processing transactions. Ethereum has committed to scaling by building out a Layer 2 ecosystem, with popular projects including Arbitrum and Optimism. Bitcoin also has a Layer 2 network called Lightning.
