As the world moves toward digital transformation, the technologies we choose will have a lasting impact on our planet. Blockchain, NFTs, and other crypto assets have attracted a lot of attention for their ability to store records securely and immutably. However, the environmental cost of maintaining these technologies is often overlooked. The energy consumption required to operate blockchains, especially those using proof of work (PoW), is enormous, contributing to the very problems of climate change and global warming that we should be working to mitigate.
In contrast, the Domain Name System (DNS), a technology that has reliably secured and managed digital assets for over 30 years, offers a sustainable and proven alternative. DNS, and in particular Whois records associated with domain names, perform similar functions to blockchain and NFTs, but with a much lower environmental impact.
The environmental assessment of blockchain and NFTs
The energy requirements of blockchain technology have always been staggering. Under the old PoW consensus model, a single Ethereum transaction could consume more energy than an average US household consumes in a day. However, following Ethereum’s transition to Proof of Stake (PoS) in September 2022, its energy consumption has decreased by over 99%, significantly reducing the carbon footprint of each transaction.
Similarly, the carbon footprint of an NFT, especially on platforms that still use PoW like Bitcoin or pre-PoS Ethereum, has been estimated at around 90 kg of CO.2 per year. Post-PoS, this figure has been significantly reduced, although the exact impact varies depending on the blockchain used. At the same time, the environmental impact of Bitcoin remains significant, with estimates suggesting it produces around 37 megatons of CO.2 annually.
DNS: a green and reliable solution
Domain names, particularly those in the DNS ecosystem, represent some of the first non-fungible digital assets. Each domain is unique and not interchangeable, sharing similarities with the concept of NFTs. Whois records associated with domain names function as an ownership registry, providing a level of transparency and security. However, it is important to note that Whois records are not inherently immutable and do not replicate the decentralized consensus mechanism of blockchain.
Consider this: the carbon footprint of a domain name is only 0.117 kg of CO2 per year, a stark contrast to that of an NFT, even in the current PoS model. DNS infrastructure, in place since the early days of the Internet, is incredibly efficient, with the energy required to maintain domain names minimal compared to blockchain technologies.
A trusted ecosystem with global reach
The domain name market is very competitive and mature, with growth rates comparable to those of the global economy. Despite this saturation, the DNS ecosystem has accumulated a high level of reliability and trust from users around the world. This trust provides a solid foundation for innovative developments, such as the patented Digital Twin process of the .ART registry.
This process adds additional fields to Whois records, providing detailed information about a work of art or object. Managed in a distributed manner by ICANN through a network of domain registrars and registry operators, these Whois records have provided a secure and trusted database for decades. This reliable digital record of artifacts meets a growing market demand, as evidenced by the continued interest in blockchain and crypto solutions, despite their inherent flaws.
Bridging the gap: domains and blockchain
While blockchain and NFT solutions are often considered inherently trustworthy, IT professionals understand that this is not always the case. Issues like the “51% attack” reveal vulnerabilities that are often overlooked due to high demand. However, the .ART registry does not pit domains against the blockchain; rather, we propose a way to combine the two in an efficient and economical way. Through the use of additional reference fields in our Whois records, domains can be linked to any cryptography solution, positioning DNS as a complementary technology that can improve the overall ecosystem.
DNS: a global and environmentally friendly alternative
As we approach the COP29 UN Climate Change Conference in Baku, Azerbaijan, it is crucial that we consider the environmental implications of our digital infrastructure. DNS and Whois records provide the ability to secure digital assets in a way that is both environmentally friendly and technologically proven. Unlike blockchain, DNS has more than 30 years of experience, with a distributed management system that guarantees security, reliability and scalability.
The COP29 conference is expected to include discussions on how DNS can be better leveraged as an environmentally friendly global data store, providing a sustainable alternative to the energy-intensive processes of blockchain and NFTs. Although DNS does not entirely replace blockchain, its role as a green technology should not be underestimated.
Conclusion
In our quest for technological progress, we must not lose sight of our responsibility to protect the planet. DNS, with its minimal environmental impact and robust security, is not only a viable alternative to blockchain and NFTs, but also a necessary alternative in the face of growing climate concerns. By choosing DNS, we are choosing a greener future.
