What is Altcoin?
Altcoins (ALT), short for alternative coins, refer to all cryptocurrencies apart from Bitcoin. They earned this name because they serve as alternatives to both Bitcoin and conventional fiat currencies.
The emergence of the first altcoins dates back to 2011, and since then, their number has grown exponentially, reaching into the thousands. Initially, these alternative coins were developed with the aim of enhancing various aspects of Bitcoin, such as transaction speeds or energy efficiency. However, more recent altcoins have been created to fulfill a diverse range of purposes, depending on the objectives set by their developers.
Given the significant presence of altcoins in the market, it’s imperative for every cryptocurrency investor to grasp their functioning. By delving into the realm of ALTs, investors can gain insights into their utility, advantages, disadvantages, and much more.
How does Altcoin work?
Altcoins (ALT) leverage the foundational blockchain technology introduced by Bitcoin, but they do not uniformly adopt Bitcoin’s Proof-of-Work (PoW) consensus model. In the PoW framework, nodes within the blockchain network compete to solve complex algorithmic puzzles periodically to validate new cryptocurrency transactions and earn rewards. While some altcoins, such as Litecoin and Dogecoin (DOGE), utilize PoW through the process of “crypto mining,” numerous other altcoins employ alternative consensus mechanisms. One prominent example is the Proof-of-Stake (PoS) algorithm, where nodes stake the cryptocurrency native to the blockchain, locking it in virtual vaults to verify transactions and earn rewards.
Prominent PoS altcoins include Ethereum, Polkadot (DOT), and Solana (SOL). As long as an ALT utilizes blockchain technology to facilitate decentralized peer-to-peer (P2P) transactions, it qualifies as a cryptocurrency.
Altcoins (ALT) typically fall into one of two categories: coins or tokens. Coins represent cryptocurrencies integrated into their blockchain’s protocol, while tokens are additional projects built on top of a coin’s blockchain. For instance, Litecoin qualifies as a coin because transactions occur exclusively within Litecoin’s proprietary network. Conversely, tokens like Chainlink’s LINK exist on platforms such as Ethereum rather than operating within a distinct “Chainlink blockchain.” Therefore, despite the “coin” designation in the term “altcoin,” tokens also meet the criteria of Altcoins as they serve as alternatives to Bitcoin.
