Cryptocurrencies vs. Crypto Tokens

In the realm of blockchain, digital assets primarily fall into two categories: cryptocurrencies and crypto tokens. While they're frequently spoken of as if they're one and the same, there's a crucial distinction to understand:

Cryptocurrencies are integral digital currencies of blockchain networks, playing a pivotal role in the operation of these networks.
Crypto tokens, on the other hand, are developed atop existing blockchain platforms and, unlike cryptocurrencies, are not fundamental to the network's operation.

Cryptocurrencies are exclusive to their respective blockchain networks, whereas crypto tokens are not. A single blockchain may support just one cryptocurrency but can host hundreds or thousands of different crypto tokens.

The term “crypto” is broadly used to encompass both kinds of assets.

What Exactly Is a Digital Asset?

Diving into the world of blockchain and cryptocurrencies for the first time? It's crucial to grasp how digital assets, cryptocurrencies, and tokens differ. Despite often being spoken about as if they're the same, these concepts have distinct characteristics. Generally, a digital asset refers to any asset that exists in a digital form, created, exchanged, and preserved electronically. Within the blockchain sphere, this encompasses both cryptocurrencies and crypto tokens.

Cryptocurrencies and tokens, both subsets of digital assets, leverage cryptography. This sophisticated method of encryption ensures the security and integrity of these assets, making it virtually impossible for them to be duplicated or fraudulently spent.

The primary distinction lies in their association with the blockchain; cryptocurrencies are the foundational assets of a blockchain, such as BTC on Bitcoin or ETH on Ethereum. Tokens, however, are generated within a platform built atop an existing blockchain, exemplified by the numerous ERC-20 tokens within the Ethereum network.

What Is a Cryptocurrency?

A cryptocurrency represents a blockchain network's inherent digital asset, capable of being exchanged, serving as a means of payment, and acting as a value reserve. It is generated by the blockchain's protocol, hence being known as the network's native digital currency. Cryptocurrencies often have roles beyond mere currency; they may be utilized for transaction fees and to motivate participation in maintaining the security of the network.

Functioning as either a medium of exchange or a store of value, cryptocurrencies facilitate the purchase of goods or services and can be saved or later exchanged for fiat money with minimal loss of purchasing power.

Cryptocurrencies are characterized by several key features:

They operate on a decentralized basis, without the need for a central issuing authority, relying instead on cryptographic code for the creation and management of transactions.
They are underpinned by blockchain technology or similar Distributed Ledger Technology (DLT), enabling system participants to apply rules in a secure, automatic, and trust-free manner.
Cryptography is essential to safeguard the infrastructure and network of the cryptocurrency, ensuring the integrity and security of transactions.

What Defines a Crypto Token?

Crypto tokens, or simply tokens, embody units of value issued by blockchain projects or entities, built upon pre-existing blockchain infrastructure. Although they are closely integrated with a network's native cryptocurrencies, they represent an entirely distinct class of digital assets.

Contrary to cryptocurrencies, which are inherent to a blockchain's protocol (like ETH is to Ethereum), tokens are generated by projects leveraging existing blockchain platforms. Ethereum's blockchain, for example, supports not just its native cryptocurrency, ether, but also a plethora of diverse tokens such as DAI, LINK, COMP, and even CryptoKitties, each serving varied roles from enabling decentralized finance (DeFi) participation to providing platform-specific utilities or gaming experiences.

There are key token standards facilitating the creation of these crypto tokens, predominantly on the Ethereum network. The ERC-20 standard facilitates the creation of interoperable tokens within Ethereum's decentralized application ecosystem, while the ERC-721 standard supports the creation of unique, non-fungible tokens (NFTs), making each token distinct and not interchangeable. The landscape of tokens is vast, with hundreds of ERC-20 tokens and thousands of ERC-721 tokens currently in circulation, a number that continues to grow as the blockchain sector evolves.

Crypto tokens are characterized by their programmability, permission lessness, trustless nature, and transparency. Being programmable means they operate on coded protocols and smart contracts that define their functionalities. Permission Lessness allows anyone to engage without needing special access, while their trustless aspect ensures operations without a centralized authority, relying instead on predetermined network rules. Transparency ensures that all transactional and protocol rules are open for verification.

Beyond their exchange value, crypto tokens can represent physical assets like real estate or art, digital commodities like computational power, or specific services and utilities. They're also instrumental in governance, allowing token holders to vote on critical project decisions. This process, known as tokenization, transforms various assets and rights into digital tokens, paving the way for a plethora of new uses within the blockchain ecosystem.

As the blockchain industry grows, so does the diversity of digital assets, catering to the complex needs of its participants from businesses to individuals. The digital asset creation process is more fluid and less bounded than in the physical world, promising to revolutionize how industries function, interact, and create value, opening up new possibilities for societal and economic innovation.

Why do Web3 projects prefer tokens?

Web3 projects typically opt for issuing tokens over creating their own cryptocurrencies due to the complexity, cost, and time required to develop a new blockchain. Leveraging existing blockchain infrastructure is a more straightforward and cost-effective approach, akin to how startups use cloud services like AWS to avoid the expenses and hassles of managing physical servers.

Tokens serve as a versatile tool for Web3 developers, facilitating user engagement and adding utility within decentralized applications (DApps). They offer a broader spectrum of applications compared to cryptocurrencies, enabling projects to tap into the security, stability, and established user base of existing blockchains. This foundation not only provides technical robustness but also a network effect, as building on a well-known blockchain brings the inherent advantage of a large, active community.

The primary focus for many developers is the creation and refinement of their Web3 offerings, be it games, decentralized finance (DeFi) protocols, or other types of DApps. The prospect of constructing and maintaining their own blockchain infrastructure, with all its attendant challenges, is a distraction they can do without. Thus, issuing tokens on established blockchains emerges as the pragmatic choice, allowing developers to concentrate on innovation and user experience without the overhead of managing a cryptocurrency's underlying technology.
