Proof of stake explained: Why is it better than Bitcoin’s PoW?

As the popularity of cryptocurrency continues to grow, it’s important to consider the environmental impact of these digital currencies.

One of the most well-known cryptocurrencies, Bitcoin, uses a system called Proof of Work (PoW), which requires miners to solve complex mathematical equations to publish new blocks. This process consumes a significant amount of electricity, contributing to the carbon footprint of the currency.

However, there is hope for a more sustainable future for cryptocurrency. Proof of Stake (PoS) is a newer system that requires users to hold a certain amount of cryptocurrency to validate transactions. This reduces the system’s energy consumption and makes it a more environmentally friendly choice.

A Tale of Two Systems: PoW vs. PoS

Imagine a vast gold mine where hundreds of miners tirelessly dig, not knowing if they’ll find gold or not.

This is the world of Proof of Work — a competitive frenzy where participants, or miners, solve complex mathematical problems to publish a new block containing the latest record transactions

The first to solve the problem wins the block reward and publishes the new block, but the combined energy of all those participants, most of whom leave empty-handed, is immense.

Now, multiply that image by thousands — representing all the miners worldwide — and you can visualize the scale of energy consumption.
