Chia cryptocurrency – A Misryoum investigation finds Chia’s energy and carbon footprint may be far higher than promoters reported, tied to hardware production and wear.
Chia, a cryptocurrency that positioned itself as an eco-friendlier alternative to Bitcoin, is drawing new scrutiny after analysis suggested it may consume far more energy and generate more emissions than its makers originally claimed.
In this context. Misryoum reports that Chia’s core approach—often described as “proof of space and time”—does not rely on the heavy. calculation-based competition used in Bitcoin’s proof of work.. Instead. it uses available storage: participants expand their chance of earning rewards by dedicating more disk space and keeping it online for longer.. Chia’s operation is typically divided into two stages. plotting and farming. with plotting requiring intense computing and memory to create the data. while farming focuses on keeping that data on disk and occasionally demonstrating it remains available.
An important part of the debate is that Chia’s “green” positioning often emphasizes the electricity used during farming. But Misryoum notes that the picture can change when the full lifecycle of the hardware is considered—especially the devices used for plotting.
A study examined how Chia affects storage equipment and how much energy is involved across the process.. The analysis indicates that plotting can cause significant wear on solid-state drives. meaning the equipment may need replacing more quickly than expected.. Researchers also considered the emissions tied to manufacturing the hardware in the first place. describing this “embodied” footprint as a major driver of the system’s overall impact.
The resulting estimates. according to Misryoum. place Chia’s likely annual carbon footprint substantially above the figure the network initially communicated.. Even the more conservative scenario in the analysis implies a gap large enough to undermine the original claim of low emissions. with the study finding that the difference is not just about day-to-day power draw.
This matters because sustainability claims for technologies like cryptocurrencies often hinge on a single metric, such as operational energy.. Misryoum highlights that when hardware production and turnover are included. environmental assessments can shift dramatically. changing how investors. policymakers. and the public interpret “green” innovation.
The analysis also points to trade-offs: attempts to reduce the burden on certain drives can increase demand on other components. such as memory and GPUs. which also carry their own environmental costs.. Even so. the study’s authors frame the findings as a more nuanced comparison rather than a simple verdict. suggesting that Chia may still be less demanding than Bitcoin’s proof-of-work model while still failing to meet the most optimistic sustainability expectations.
Chia Network leadership. as discussed by Misryoum. has acknowledged that the analysis is not wildly off while arguing that reported totals may reflect assumptions that overstate worst-case conditions—particularly around how the carbon costs of drive manufacturing are counted.. The company also points to planned changes to its protocol, describing upcoming upgrades as a pathway to reduce emissions.
Misryoum’s takeaway is that the next wave of “cleaner” blockchain designs will likely be judged not only by how efficiently networks run, but by how responsibly they source and use the physical infrastructure that makes them possible.
