Understanding the Crucial Applications of Cryptocurrencies
Written on
Cryptocurrencies are often questioned for their necessity and real-world applications. This article delves into seven significant use cases that most digital currencies tend to embody. Although this list may not cover every possible application, it provides a comprehensive overview of how cryptocurrencies function in various contexts.
# 1 — Payment
The most immediate association with cryptocurrencies is as a medium of exchange. Many coins and tokens aim to facilitate decentralized payment methods, which can be categorized into three main groups:
- Stablecoins: These are digital assets tied to the value of fiat currencies, designed to minimize price volatility. Examples include UST, USDC, and DAI.
- Peer-to-Peer Currencies: These assets allow users to buy or sell products, both digital and physical, positioning themselves as alternatives to conventional money. Notable examples are XRP, XLM, and ZCash.
- Micropayments: Designed for small transactions, these assets allow users to pay minimal fees across various networks. Initially, Dogecoin was used for tipping content creators, while MIOTA facilitates payments between smart devices.
Example Token (Stablecoins)
Stablecoins maintain a stable value, often pegged to traditional currencies like the USD. This stability makes them a reliable option for transactions. Platforms that allow users to earn interest on stablecoins include:
- Celsius
- Nexo
- Blockfi
- Crypto.com
- Gemini
- Abra
- YouHodler
- Ledn
- Anchor Protocol
Some popular stablecoins include BUSD, DAI, USDC, and USDT.
# 2 — Transaction (Gas) Fees
Transaction fees play a vital role in blockchain networks, being essential for various user actions such as buying, swapping, and contract execution. There are two primary reasons for these fees:
- Network Security: Without transaction fees, networks become vulnerable to spam attacks, risking their stability. This issue is especially relevant in smart contract execution, where every action incurs a cost.
- Node Incentivization: Miners and validators receive tips through these fees, increasing their likelihood of processing transactions.
Example Token (ETH)
Ethereum utilizes its native token, ETH, to cover transaction fees across various activities, including:
- Transferring ETH between wallets
- Swapping for other ERC-20 tokens
- Purchasing NFTs
- Engaging in play-to-earn games
- Participating in decentralized finance (DeFi) protocols
Regardless of the activity, transaction fees are mandatory, incentivizing network participants.
# 3 — Incentives
Miners and validators are responsible for validating transactions on blockchains, securing the network through computational efforts or staking. To encourage their participation, various incentive structures are in place:
- Mining Incentives: In Proof of Work (PoW) systems, miners receive rewards in the form of native tokens for successfully mining blocks.
- Staking Rewards: In Proof of Stake (PoS) systems, validators earn rewards for validating transactions based on the tokens they stake.
Example Token (ATOM)
ATOM serves as the native token for the Cosmos blockchain, offering three key functionalities:
- Voting on proposed changes
- Staking for rewards
- Covering transaction fees
On its launch in late 2017, ATOM tokens were distributed among various stakeholders, including the Interchain Foundation and early donors.
# 4 — Governance
Governance in blockchain projects is a complex issue, primarily addressing how updates and changes to protocols are decided upon. Without a clear agreement, forks in the project can occur, as seen in Bitcoin's history. To address this, governance tokens are introduced, allowing holders to propose and vote on changes.
Example Token (YFI)
YFI, the governance token of the yearn.finance protocol, facilitates decision-making within the platform. The governance process involves:
- Discussing proposed changes on community forums.
- Submitting proposals for review.
- Voting on proposals with YFI tokens.
- Implementing changes based on majority support.
# 5 — Utility Token
Utility tokens represent the most prevalent use case for cryptocurrencies, providing various functionalities across platforms. Common examples include:
- Fan Tokens: Allow users to support artists or teams with perks like performance bonuses.
- Platform Privileges: Tokens can grant users discounts, VIP access, or other benefits on exchanges.
- Gaming and NFTs: Many blockchain games utilize tokens for in-game assets and trading.
Example Token (SAND)
SAND is an ERC-20 token integral to the Sandbox ecosystem. It serves multiple purposes, such as:
- Acquiring in-game assets
- Uploading to the marketplace
- Voting on governance matters
- Earning passive income through staking
# 6 — Equity Token
Equity tokens are essential in the DeFi space, allowing users to participate in decentralized finance without intermediaries. They represent locked assets in liquidity pools and enable users to claim back their contributions.
Example Token (bLuna)
The Terra blockchain employs two token types:
- Stablecoins (TerraX): Algorithmically pegged to fiat currencies, like UST.
- LUNA: A multi-functional token used for governance, staking, and price stabilization.
Delegators wishing to stake LUNA must consider a bonding period of 21 days, but tokens like bLuna provide liquidity options during this time.
# 7 — Store of Value
Cryptocurrencies, particularly Bitcoin, are often referred to as "digital gold" due to their perceived value retention qualities. Many view Bitcoin as a hedge against inflation and market instability.
Example Token (BTC)
While Bitcoin lacks smart contract capabilities, it has gained recognition as a store of value. Companies like Tesla and nations such as El Salvador have adopted Bitcoin for transactions, reinforcing its status as a long-term asset.
# Final Thoughts
