PoS

Crypto mining validates transactions using powerful computers in Proof-of-Work (PoW) blockchains like Bitcoin, requiring significant hardware and electricity costs. Crypto staking, conversely, involves locking up existing cryptocurrency in Proof-of-Stake (PoS) networks to secure the blockchain and validate transactions, providing passive income with lower energy use and capital investment.

As of 2025, Bitcoin (BTC) and Ethereum (ETH) remain the undisputed titans of the cryptocurrency world. Their dominance is not only a reflection of their historical importance but also of their continued relevance in driving market sentiment, innovation, and institutional interest.

As the blockchain space matures, new and existing networks vie for dominance in scalability, speed, developer experience, and ecosystem growth. Two standout contenders are Solana (SOL) and Sui (SUI).
