I'm trying to understand the distinction between 
Solana and Bitcoin. I know they are both cryptocurrencies, but what are the key differences in terms of their technology, transaction speed, and use cases?

    In contrast, Ethereum, another major cryptocurrency, initially employed PoW but is now in the process of transitioning.

    Ethereum aims to adopt a more scalable consensus mechanism known as Proof of Stake (PoS).

    PoS promises to address some of the limitations of PoW, including its high energy demands.

    Bitcoin, the forerunner in the cryptocurrency realm, utilizes Proof of Work (PoW) as its consensus mechanism.

    This PoW method, though known for its robustness and security, requires significant energy consumption.
