Crypto mining has not had the best reputation so far. This technology has been accounting for things like colossal amounts of energy, environmental costs, and, of course, those increasingly distinct carbon shadows.
In 2021 alone, crypto mining activities caused emissions of 139 × 106 tons of CO2-eq, around 0.4% of global carbon emissions in 2021
But in a twist that no one saw coming, blockchain innovators are turning over a new, greener leaf.
Enter the Green Blockchain: an environmental spin on the crypto world’s usage of energy.
With the rise of environmental consciousness in recent years, blockchain pioneers are remastering mining by embodying the excitement of trading digital gold for clean energy practices that might even draw the attention of the nature deity, Mother Nature herself.
The Origin of Green Blockchain
The idea of the ‘Green Blockchain’ emerged in response to emerging criticism for crypto mining’s extensive environmental harm. Typically, the existing decentralized blockchains, including Bitcoin and Ethereum, use an approach known as “proof of work” to authenticate payments.
In layman's terms, it involves using computers to solve difficult math problems, and whoever solves the problem gets to add the next block of data to a blockchain.
However, this process requires huge amounts of electricity, sometimes more electricity than some countries use in a year.
Why Is Crypto Mining Bad for the Environment?
“But why is mining cryptocurrency bad for the environment?”
Mining cryptocurrency is considered to be an energy-cost affair because of how the mining process is done.
Almost all cryptocurrencies use a consensus method known as “proof of work” (that we’ve mentioned before) in which computers compete to solve problems first to verify transactions and earn some coins in return. This race needs a tremendous amount of computation, and so more energy is used to feed these computers and their related systems.
The problem is compounded when electricity is generated using sources such as coal or natural gas, thus increasing carbon footprint. To that, one must consider that mining these cryptocurrencies themselves produces heat, often requiring the use of cooling systems to handle, and this is where you have the formula for environmental pressure.
In essence, the energy consumption by crypto mining can be as bad as that of some of the biggest polluters.
As climate change was disclosed, many people– including crypto lovers, began to ask themselves whether the advantages of blockchain could compensate for the environmental impact.
As such, there was growing pressure to come up with solutions that offered some form of preservation of the environment, and this was the trigger for the development of what has come to be termed Green Blockchain.
At the time of the writing of this article, Green Blockchain can be described as a blockchain network that was developed from this perspective. Instead of proof of work, they often use other methods, such as “proof of stake,” which consumes far less energy.
How Does Green Blockchain Work?
Green Blockchain employs the more efficient approaches to energy use due to the primary focus on reducing the emission of energy as a product of its operation, for instance, by not using the conventional ‘proof of work’ model.
The most popular of them is known as the ‘Proof of Stake.’ Unlike the energy-consuming computers striving to solve complex problems, proof of stake permits users to validate transactions proportionate to their amount of cryptocurrency and their willingness to risk them. This effectively helps to reduce energy usage because no powerful hardware is required.
The other approach is the utilization of renewable energy in the mining undertakings. Efforts are underway to incorporate renewable sources such as solar and wind energy and hydroelectric power into crypto mining centers to minimize the use of fossil energy.
Some blockchain networks also have carbon offsets and spend money on environmental projects such as tree planting to cater to carbon footprints.
In addition, some projects reduce the energy consumption of algorithms or create systems that utilize excess computer capacity– e.g., from other computers. Combined, these measures make Green Blockchain not only feasible but also a notion that Bitcoin and other similar forms are improving the world’s sustainability.
The Benefits of Green Blockchain
However, the Green Blockchain is not only about helping our planet. It is also about evolving the future of the cryptocurrency market. With reference to the challenges posed by regular cryptocurrency mining in the environment, Green Blockchain technology provides a much-needed way to achieve sustainability.
Fighting energy consumption, hurricane and earthquake resilience, and enhanced image are initiatives that demonstrate that green is not equal to unprofitable in the concept of blockchain. In this section, we’ll dive into how greenness is a win for both the planet and the whole crypto spectrum.
1. Reduced Energy Consumption
Another fundamental selling proposition of Green Blockchain is that it is prepared to lessen energy consumption significantly. Such shifts from “proof of work” to introducing “proof of stake” make the potency required to validate transactions within the network extremely low.
For instance, Ethereum's move from proof of work reduced energy consumption by 99.99% (According to the Crypto Carbon Rating Institution)-- we will talk more about this in the next section.
This not only decreases the expenditure on operational factors for the miners and network participants but also decreases as a result of the high electrical consumption in the environment.
2. Lower Carbon Footprint
Green blockchain minimizes the amount of carbon emitted during crypto mining activities. The conventional modes of operation entail the use of fossil fuels. Hence, the carbon emission is high. Its networks assume to decentralize their mining operations and use solar or wind, or hydroelectric power to run them.
The transition from proof of work to proof of stake assists in combating emissions of greenhouse gases, thus ensuring that the mining of cryptocurrencies is eco-friendly. Moreover, more and more blockchain projects today are also financially supporting reforestation, which undoubtedly positively contributes to the climate issue. It also has a major role to play in ensuring the crypto industry is moving in line with worldwide sustainability initiatives.
Take Chia Network, for example, a project that was designed to be green on purpose. Chia makes proof of space and time based on unused storage hard drive space instead of (energy inefficient) proof of work, which saves tons of energy and emissions.
3. Improved Public Perception and Adoption
Specific public perception always influences the further development of any business field, and the sphere of cryptocurrency is not an exception. Another way to improve the network image and demonstrate the ability to contribute to the sustainability of the planet is by adopting Green Blockchain technologies.
This shift also has the practical effect of appealing to those investors who want to make money while consuming less energy but also speaks to others who might not support an industry because of how energy-intensive it is.
By promoting the general acceptance of cryptocurrency among conscious customers and both large and small businesses, Green Blockchain can make the usage of cryptocurrency more attractive and profitable for those who are interested in sustainable investments and technologies.
4. Sustainability and Business Scalability for the Long-Term
Green Blockchain also focuses on the more extended development and growth of the Bitcoin market. Since cryptocurrencies are constantly being adopted, mining is going to continue to be needed. Such methods point to conventional techniques of mining that cannot continue in the same manner without worsening the situation.
With the help of such energy savvies as algorithms, renewable energy resources, and proof of stake, Green Blockchain guarantees that the expansion of blockchain networks will not exceed the capabilities of the Earth.
5. Cost Savings for Participants
Green Blockchain saves energy, which means miners and the network participants will have to pay less operational costs. Conventional mining rigs consume a large amount of energy to operate, which makes for expensive utility bills.
Shifting to proof of stake or renewable energy sources allows them to save money while leaving (or even increasing) network security intact. These reduced costs help establish Green Blockchain as both an organic and economic solution that helps encourage further participation within the crypto ecosystem.
6. Incentives for Innovation
Search for green BlockchainSolutions leads to better tech making. Now, developers are thinking outside the box to create more energy-efficient applications by building blockchains that utilize unused computing power or algorithms that dynamically adapt to changes in energy supply.
While striving for sustainability, development in blockchain technology continues on many other fronts and gives benefits in the supply chain management, health care, and even entrainment sectors. With this, Green Blockchain is not only transforming crypto but also expanding the horizon of the latest technology across sectors.
7. Alignment with Regulatory Trends
Not only is the crypto industry facing stricter environmental laws, but governments and regulatory bodies around the world are also hiding in those. By complying with these standards, Green Blockchain stays ahead of the curve.
Sustainable networks are more likely to avoid penalties for non-compliance with regulators, which may otherwise impose fines or other bans and limits on operations. Being aligned with environmental sustainability policies not only guarantees operations but also builds trust with governments and investors – an essential move for long-term success.
Top Green Blockchain Projects or Innovations
Given this, a few exciting projects and endeavors have emerged to spearhead the charge for a more environmentally friendly blockchain industry. These trendsetters are paving the way to revolutionize the way that some blockchain networks function while showing that sustainability, though previously the domain of the theoretical and the idealistic, can be not only achievable but also viable from a business perspective.
Here are three examples:
Ethereum’s Moving from Proof of Work to Proof of Stake
Ethereum hit the news in the second year of its launch with its critical upgrade from proof of work to proof of stake, also known as The Merge. This upgrade cut Ethereum’s energy consumption by more than 99% and thus became the new benchmark for blockchain energy efficiency.
The proof of stake system is the more efficient system of validation that needs the validators to lock their cryptocurrency to advance as the miners instead of burning the electricity. It also made Ethereum less carbon-intensive and encouraged other projects to do the same thing as well.
Chia Network’s “Proof of Space and Time”
We’ve mentioned Chia Network before. It has pioneered what they called “the proof of space and time” and even created some buzz on social media. Unlike most cryptocurrencies that employ heavy computation, Chia utilizes the unused space of a hard drive to guarantee the security of its network.
In return, they can pledge some of their extra hard drive storage space to become a validator with much lower energy consumption than mining. This new model has received attention as a sustainable option for those interested in blockchain and developers.
SolarCoin
SolarCoin is a special form of blockchain project intended to generate solar energy. In return for every megawatt hour of solar power produced, they get paid through SolarCoins, which is a form of cryptocurrency. Look at this video as a part of their video marketing strategy.
Solarcoins - and how to get them!
This initiative supports the use of renewable energy through an added favor for producers of solar energy. SolarCoin fits within the objectives of the Green Blockchain in that it promotes the adoption of solar energy solutions directly as the decentralized system affirms and rewards the use of solar energy.
Wrapping Up: What the Future Holds?
The crypto industry has seen the emergence of Green Blockchain as one of the most significant events that will define the market’s future and focus on the development of innovations tied to sustainability.
The hope is also for widespread adoption of energy efficiency, renewable energy sources, and better ideas on how to reduce the footprint of the blockchain. With this evolution, cryptocurrencies can finally part ways with their image of ‘costing the earth’ and reinvent themselves as paragons of environmentalism.
But challenges remain. The deployment of green solutions within every blockchain network will also be a major investment with the need for a global effort and circumventing technical barriers.
Public awareness will also be important in making and sustaining the necessary changes, and integration with the government and appropriate regulatory bodies will also be important in the long run.
At the end of the day, the buzz surrounding Green Blockchain cannot be fully stripped off the pack as a result. At this point, the crypto industry has to address the environmental issue to be part of the solution that the world needs to pursue, that of a future in which technology will become sustainable without harming our planet.
