Continue reading this blog to learn about the in-depth concept of green blockchain, by featuring all the challenges, and solutions that can impact sustainability and how the innovation works to reshape the future of digital technologies.
What is Green Blockchain?
As the term speaks for itself, Green blockchain is a term that defines the usage of blockchain technology that prioritizes energy efficiency, sustainability, and environment-friendly practices. The usage of traditional blockchain, raises concerns over multiple diaphragms especially on those who employ the PoW consensus mechanism, using computational power and energy to validate the transactions and provide security to the network. This process led to criticism about the environmental footprint of blockchain networks especially in large-scale mining operations while contributing to the significant carbon emissions.
The innovative invention of green blockchain focuses on finding an alternative mechanism besides PoW and the algorithm that incorporates energy efficiency minimizing the cost of consumption. As the PoW was not that successful to partner with green blockchain, the Proof of Stake (PoS), and Delegated Proof of Stake (DPoS) are designed to reduce the environmental impact on blockchain transactions. Blockchain aims to integrate sustainable practices in blockchain’s broader ecosystem promoting use cases that directly benefit the environment.
The Environmental Impact of Traditional Blockchain
High Energy Consumption
The mainstream concern around traditional blockchain was Bitcoin and Ethereum, and their maximum energy consumption. Bitcoin works on a PoW consensus mechanism where the miners complete the whole mathematical puzzle to add new blocks to the blockchain. The process is known as mining. Which requires a vast amount of electricity for the mining rigs, cooling systems, and other infrastructure.
As per market stats, the price of Bitcoin rises and the activities of mining intensify by increasing the whole energy consumption. Energy demands a couple of facts: much of electricity is used as a fossil fuel making Bitcoin a controversial practice from environmental aspects.
Ethereum’s second-largest blockchain network has been employing the PoW for a long time, but now the transitioning of upgraded Ethereum 2.0 works on Proof of Stake (PoS). The shift works on reduced energy usage that dramatically utilizes the estimates suggesting Etherum’s energy consumption can drop up to 99.95%.
Carbon Emissions
The energy that was used in the conventional blockchain networks often comes from non-renewable sources that contribute to carbon emissions. The raised count on carbon footprint maximizes the concern as many mining operators are located in regions where the cost of electricity is less by much when they utilize coal and other fossil energies to conduct mining.
As the world moves towards climate change mitigation, industries, and the blockchain space increase the pressure to adopt sustainable practices. The carbon emissions elevate traditional blockchain networks that are contributing to global warming and pose a significant challenge to the environment.
The Solutions for a Greener Blockchain
Proof of Stake (PoS)
The adoption of the Proof of Stake (PoS) comes up as a primary solution for the green blockchain. Unlike the PoW, where miners need to solve mathematical puzzles to validate the transaction, PoS relies on validators where the user needs to select the amount of cryptocurrency they want to stake in the network. The significant reduction in the computational power needed to secure the network where there is no need for resource-intensive mining.
The shift of Ethereum from using PoW to PoS is one of the most successful yet notable examples of blockchain networking embracing the scalability and environment-friendly approach of Proof of Stake (PoS).
Delegated Proof of Stake (DPoS)
Another energy-efficient consensus mechanism is Delegated Proof of Stake (DPoS). The DPoS is similar to PoS which works to provide the democratic layer of the consensus process instead of validating each participant. The DPoS allows users to vote for a small number of delegates which are responsible for validating the transactions on behalf of users.
The DPoS reduces energy consumption by limiting the number of validators to develop a more efficient and scalable system. Blockchains that employ DPoS such as the EOS and the TRON, are more proficient than Bitcoin which utilizes PoW-based blockchain. That is the reason, they are more preferred alternatives for green blockchain initiatives.
Hybrid Consensus Mechanisms
The Blockchain networks are useful for exploring the hybrid consensus mechanism that combines PoW and PoS to balance decentralization, security, and energy efficiency. The Horizon blockchain utilizes the hybrid model combining the security of PoW with the energy efficiency of PoS. These hybrid systems are aimed to leverage the benefits of both the consensus (PoW & PoS) while reducing the respective drowning aspects.
Renewable-powered Mining
Another solution to manage the environmental issues associated with the blockchain is to shift the mining operations toward renewable energy sources. While it does not address the inefficiency of PoW, it reduces the carbon footprint of blockchain networks using clean energy that promotes mining activities. Several blockchain projects are already working on creating currency mining farms powered by Solar, wind, and hydroelectric power generators.
Projects like Bitcoin Mining Councils push the transparency in energy usage and encourage the miners to adopt cleaner energy sources. It showcases the maturity in industry, across mining operations with the transitions to renewable energy while further reducing the environmental impact on the blockchain networks.
Layer 2 Solutions
The development of Layer 2 solutions is built on existing blockchains enabling faster, cheaper, and more energy-efficient transactions. The processing of this off-chain and the only settling final state allow the Layer 2 solutions to drastically reduce the load on primary networking leading to reduced energy consumption.
The Lightning Network is a Layer 2 solution for Bitcoin that enables instant low-cost transactions without burdening the main blockchain. These solutions are useful to scale up the blockchain’s efficiency while reducing the whole environmental impact.
