Green Crypto's Energy Secret: 18x More Power Used

A recent investigation into the Chia Network, a cryptocurrency promoted as an environmentally friendly option, has uncovered significant discrepancies in its energy consumption claims. Researchers found that Chia's actual energy usage is approximately 18 times greater than the 50,000 tonnes initially stated by its creators. This figure places its carbon footprint significantly higher than many other major blockchains.

The primary driver of this elevated energy use is the "plotting" process, which is crucial for Chia's proof-of-space-and-time mechanism. This process intensely utilizes and wears out solid-state drives (SSDs), leading to considerable embodied carbon emissions from hardware manufacturing. Researchers estimate that creating just 160 plots could destroy a new SSD.

While Chia Network's CEO acknowledged the figures might not be "wildly off," he argued they represent an overestimate by including the full carbon footprint of drives that have already served years in enterprise data centers. He emphasized that Chia creates a market for such discarded hardware, preventing it from being landfilled.

Looking ahead, the Chia Network is preparing to launch "Proof of Space 2.0" in two months, a system they anticipate will substantially lower the network's environmental impact. The company expressed confidence in their ongoing efforts to improve efficiency and sustainability.
