Could you elaborate on the mechanics of proof-of-work cryptocurrencies? Specifically, how does the consensus mechanism function in ensuring the integrity of the blockchain? I'm curious about the role of miners, the computational power they contribute, and how that leads to the validation of transactions. Additionally, I'd like to understand the concept of 'difficulty' and how it adjusts to maintain a stable block generation rate. Lastly, what are some of the key trade-offs and challenges associated with proof-of-work systems, especially in terms of energy efficiency and scalability?

Cryptocurrencies employing the Proof-of-Work consensus mechanism often undergo a significant event known as "halving".

This event is programmed to occur after a predetermined number of blocks have been appended to the blockchain.

However, as time progresses and more blocks are mined, the reward for each block decreases by half.

The purpose of halving is to regulate the number of new coins entering circulation through the mining process.
