Altcoins, short for "alternative coins," refer to any cryptocurrency other than Bitcoin. Since Bitcoin's inception in 2009, thousands of altcoins have emerged, each aiming to improve upon or offer alternatives to Bitcoin’s functionality.
Understanding Altcoins
Origins of Altcoins
Bitcoin’s open-source code allowed developers to create new cryptocurrencies by modifying its protocol. The first altcoin, Namecoin (NMC), launched in 2011, introduced decentralized domain registration.
Key Differences from Bitcoin
Altcoins often differ in:
- Consensus mechanisms (e.g., Proof-of-Stake vs. Proof-of-Work).
- Transaction speed (e.g., Litecoin’s 2.5-minute block time vs. Bitcoin’s 10 minutes).
- Supply limits (e.g., Ethereum’s uncapped supply vs. Bitcoin’s 21 million cap).
