Environmental Impact of ASIC-Resistant Coins: Report by MiCA Crypto Alliance and Nodiens

The MiCA Crypto Alliance, in collaboration with Nodiens, has published a new report examining the environmental trade-offs of ASIC-mined versus ASIC-resistant Proof-of-Work (PoW) cryptocurrencies throughout 2024. The study leverages proprietary data from Nodiens offering an in-depth analysis of energy consumption, carbon emissions, and electronic waste linked to both mining models.

ASIC-resistant coins are cryptocurrencies designed to prevent the use of specialised ASIC (Application-Specific Integrated Circuit) hardware in mining, aiming to maintain decentralisation by allowing more participants to mine using general-purpose equipment. This design choice aims to prevent the mining power from becoming concentrated among a few with access to costly ASIC machines.

‍

The report highlights a nuanced dilemma faced by the blockchain community: while ASIC miners deliver superior efficiency per unit of computational power, ASIC-resistant coins tend to be less energy- and carbon-intensive on a per-transaction basis. This contrast underscores the ongoing challenge of balancing decentralisation, central to blockchain’s ethos, with the imperative of environmental sustainability.

‍

By analysing key environmental metrics, the report provides critical insights into how different PoW mining approaches impact energy use and ecological footprint. ASIC mining, despite its efficiency, often concentrates power in fewer hands due to the specialised and costly nature of hardware. Conversely, ASIC-resistant coins aim to promote wider participation by preventing ASIC dominance, yet this can lead to increased overall resource consumption per transaction.

The report aims to equips investors, researchers, and policymakers with valuable data to better understand the trade-offs inherent in fundamental design choices. The findings encourage a more informed dialogue about how blockchain networks can evolve to remain both equitable and environmentally responsible.
