#BTCvsETH Bitcoin (BTC) operates with a consensus model based on Proof-of-Work (PoW), prioritizing security and immutability. Its fixed supply of 21 million units reinforces its role as a digital store of value. The network is highly decentralized, but there are limitations regarding scalability and programmable functionality.

Ethereum (ETH), on the other hand, has evolved to Proof-of-Stake (PoS), reducing energy consumption and allowing greater flexibility in updates such as sharding and the integration of layer 2 with rollups. Its focus is on functionality, being the main infrastructure for smart contracts, decentralized applications (dApps), and tokens via the ERC-20 standard.
