A pool full of water for every transaction

That's it Bitcoin costs the environment dearly. Not only does it burn more electricity than η Ελλάδα αλλά χρειάζεται και τεράστια ποσότητα νερού. Σύμφωνα με τα πρόσφατα στοιχεία στην επιθεώρηση Cell Reports Sustainability, κάθε συναλλαγή με Bitcoin καταναλώνει 16.000 λίτρα νερού. Η συγκεκριμένη ποσότητα είναι ικανή να γεμίσει μια πισίνα μεσαίου μεγέθους. Αυτό συμβαίνει καθώς το δίκτυο υπολογιστών που διεκπεραιώνουν τις με BTC έχει ανάγκη μεγάλες ποσότητες νερού για την ψύξη. Το ίδιο συμβαίνει και με τους θερμοηλεκτρικούς σταθμούς που τροφοδοτούν τους υπολογιστές με ενέργεια.

Experts του Πανεπιστημίου του Άμστερνταμ αναφέρουν σε μελέτη τους ότι μόνο το 2021 το of Bitcoin consumed almost 1,6 trillion. liters of water. By 2023 the total quantity is expected to reach 2,3 trillion. liter. At the same time the amount of water required for a credit card transaction is 6,2 million times less.

Why Bitcoin mining burns so much electricity

The heavy water consumption by the Bitcoin network adds to the huge energy footprint left by the world's leading cryptocurrency. Researchers at Cambridge University have concluded that Bitcoin consumes the same amount of electricity as Poland each year. Considering the practice of "proof of work" in mining, most of this energy is consumed in complex and sequential mathematical calculations "without substantial feedback" during mining.

It is noted that every time a Bitcoin transaction takes place, miners in different regions of the world engage in an online race to complete the transaction and receive the corresponding commission in BTC. Specifically, the transaction is awarded to the first miner to solve a complex mathematical problem. Every second that follows, miners around the world submit 350 quintuple million candidate mathematical solutions, of which only one will eventually be used and rewarded with Bitcoin.

The rest of the data is calculations that serve no other purpose and are discarded , the Dutch researchers also report. In this direction, they are calling for a change in the Bitcoin mining model through the creation of a net zero cryptocurrency market.
