Cryptocurrencies are digital assets designed to act as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.
Blockchain networks generate and manage cryptocurrencies, which you can use to buy goods and services online or exchange for traditional currency. Popular cryptocurrencies include Bitcoin, Ethereum, Ripple, Litecoin, and many more.
Here is a brief overview of the ten most popular cryptocurrencies and how they work.
Bitcoin (BTC)
Bitcoin is the world’s first and most popular cryptocurrency. It was created in 2008 by an unknown person or group using the pseudonym Satoshi Nakamoto. It uses a decentralized ledger system known as blockchain to record transactions, and it operates on a peer-to-peer network where users can send and receive payments directly.
Bitcoin uses a consensus mechanism called Proof-of-Work (PoW) to secure its network. In this mechanism, miners must use their computing power to solve complex mathematical puzzles to process a transaction and add it to the blockchain. When miners find the correct answer, the blockchain rewards them with newly created bitcoins.
Ethereum (ETH)
Ethereum is an open-source platform that developers can use to create decentralized applications (dApps). It enables developers to build and deploy smart contracts, self-executing agreements running on the blockchain without any third-party interference. It also has its cryptocurrency, ETH, used to pay for transaction fees or fuel dApps.
Ethereum uses a consensus mechanism called Proof-of-Stake (PoS) to secure its network. In PoS, blockchain validators must “stake” their ETH to participate in the consensus process and receive rewards for validating transactions. The transition of ETH from the energy-intensive PoW to PoS is called “The Merge.”
Ripple (XRP)
Ripple is a real-time gross settlement system designed for international financial transactions. Its native currency is XRP, which can be used as a bridge currency between different currencies when transferring money across borders. Many banks and other financial institutions worldwide are currently utilizing the Ripple network.
Ripple uses a consensus mechanism known as the Ripple Protocol Consensus Algorithm (RPCA) to secure its network. The consensus does not rely on miners to process transactions but rather on validators selected by the network and receive rewards for verifying transactions. The RPCA also allows users to customize their transaction fees and speeds.
Cardano (ADA)
Cardano is a decentralized platform that uses the Proof-of-Stake algorithm to validate transactions on its blockchain. Charles Hoskinson, one of the co-founders of Ethereum, founded Cardano to improve upon existing cryptocurrency protocols through a unique consensus model and enhanced scalability.
Cardano uses a consensus mechanism called Ouroboros to secure its network. Ouroboros does not rely on miners to process transactions but rather on validators selected by the network and receive rewards for verifying transactions.
The Ouroboros protocol design is more energy efficient than other PoW or PoS algorithms, and its consensus model is resilient to malicious attacks.
Ouroboros provides a provable way of selecting validators randomly.
Tron (TRX)
Tron is a blockchain-based platform facilitating payments, content creation, and peer-to-peer file sharing. Its native currency is Tron (TRX), whose utility is to purchase content or pay for services.
Tron uses a consensus mechanism called Delegated Proof-of-Stake (DPoS) to secure its network. In this mechanism, network users can vote for delegates responsible for validating network transactions. The delegates receive newly minted TRX tokens for their services.
The DPoS consensus model design is faster and more energy efficient than other PoW or PoS algorithms, allowing for improved scalability.
Tron also enables users to create custom tokens on its network, allowing them to tokenize assets or launch their crypto projects. Tron is, therefore, an attractive platform for developers and entrepreneurs who want to start their blockchain-based projects.
Avalanche (AVAX)
Avalanche is a decentralized platform that allows users to create and run their applications (dApps) on its blockchain. It utilizes a novel consensus algorithm called Avalanche Consensus, which strives to provide greater scalability and faster transaction times than other proof-of-stake blockchains. Its native currency is called Avalanche (AVAX).
Avalanche Consensus design allows faster transaction times and greater scalability than other PoS consensus algorithms.
The Avalanche family of protocols leverages repeated sub-sampled voting in validator decisions about transactions. When a validator evaluates the acceptance of a transaction, it polls a small, randomly selected set of validators for their preference. These validators may then reply with similar or conflicting transactions. If enough validators (alpha α) respond with the same transaction, then that is considered adopted, and the decision is final. This sub-sampled process and its quick majority voting allow transactions to be quickly accepted or rejected without requiring input from all the graph’s validating nodes.
It also includes a staking mechanism that allows users to earn rewards for validating transactions on the network. AVAX tokens are the base currency in this system, and holders can stake their tokens to earn rewards. The mechanism incentivizes users to help secure the network, making Avalanche an excellent choice for those interested in staking their crypto.
Solana (SOL)
Solana is a blockchain designed to provide high-performance, secure, and scalable infrastructure for decentralized applications. It utilizes a novel consensus algorithm called Proof of History (PoH) which provides fast transaction speeds while maintaining decentralization and security. Its native currency is called Solana (SOL).
Proof of History (PoH) is a novel consensus algorithm that utilizes the timestamps of previous blocks to create a “proof” to validate transactions. It ensures that all nodes in the network agree on the chronological order of events and prevents double-spending.
Additionally, Solana utilizes sharding technology to break up its data into smaller chunks to process faster. As a result, Sharding enables greater scalability than many other blockchains and allows Solana to process thousands of transactions per second.
Solana also includes a staking mechanism, allowing users to earn rewards for validating blocks on the network. Holders can stake their SOL tokens to earn rewards.
Tether USD (USDT)
Tether USD (USDT) is a stablecoin backed by U.S. Dollars and is therefore fixed one-to-one exchange rate with the Dollar. It is commonly used in cryptocurrency trading to transfer between exchanges and to hedge against market volatility.
Tether mints Tether USD when users deposit U.S. Dollars into the Tether reserve, where they back each token by one Dollar. The token’s value will never dip below $1, making it a safe asset to store in market uncertainty.
Additionally, Tether USD uses an open-source network called the Omni Layer built on the Bitcoin blockchain. As a result, it uses the same infrastructure as Bitcoin and benefits from its secure and decentralized nature.
Polygon (MATIC)
MATIC is the native currency of the Polygon blockchain, an Ethereum-based platform designed to provide scalability solutions. It uses a layer-two scaling solution called Plasma, which allows users to process transactions off the main blockchain to reduce congestion and fees.
The Proof-of-Stake (PoS) consensus mechanism secures the Polygon network. In PoS, validators stake their tokens to validate transactions on the network; the network then rewards them with transaction fees for their services.
The Plasma scaling solution design is more efficient than other Ethereum-based solutions, such as sharding or sidechains. It also allows users to process larger volumes of transactions with lower fees and faster speeds.
Polygon also provides developers with tools to create custom tokens with multiple applications making it an attractive platform for entrepreneurs who want to launch their blockchain-based projects.
DogeCoin (DOGE)
DogeCoin is a decentralized peer-to-peer cryptocurrency created as a joke in 2013. Despite its humorous origins, Dogecoin quickly gained popularity due to its fun and friendly nature, and it now has one of the largest market capitalizations of any altcoin.
DogeCoin uses a Proof-of-Work (PoW) consensus to secure its network. Miners use their computing power to solve complex mathematical problems, validate transactions, and receive rewards. The miners get rewarded in DOGE for their work.
Factors to consider when buying a cryptocurrency
1. Market Capitalization: The total value of a cryptocurrency’s circulating supply multiplied by the current price is known as its market capitalization. This metric is an important indicator of how established and valuable a crypto project is.
2. Network Security: It is essential to consider the security of a cryptocurrency’s network when investing. Cryptocurrencies can be vulnerable to attacks with weak consensus protocols or insufficient miner hashing power. Investing in cryptocurrencies with solid and secure networks will help protect your funds from malicious actors.
3. Transaction Fees: Different cryptocurrencies charge different transaction fees, so it is essential to consider this before investing in a particular token.
4. Development Activity: The level of development activity within a project can provide insight into its prospects and whether there is potential for growth. If a cryptocurrency has experienced developers actively working on its code, it is likely a good investment.
5. Market Trends: Before investing in a cryptocurrency, it is essential to research the project’s current market trends and price movements. Market trends help you make an informed decision about whether or not the token has growth potential. Additionally, keeping track of news regarding a particular project can give insight into its prospects.
