The most eco-friendly blockchain networks in 2022

2022 noticed the continued development of inexperienced crypto tasks as extra {industry} firms centered on sustainability to cut back carbon emissions. A collection of elemental forces drove the paradigm shift, together with person calls for for quicker and extra energy-efficient blockchains, rising local weather change consciousness amongst traders, and rising authorities considerations about vitality consumption within the crypto sector.

Among the many most notable eco-friendly crypto developments in 2022 was the transition of the Ethereum blockchain from a proof-of-work (PoW) to proof-of-stake (PoS) consensus layer. The Merge, accomplished in September, joined the unique execution layer of Ethereum with its new PoS consensus layer, the Beacon Chain. It eradicated the necessity for energy-intensive mining by enabling the community to be secured utilizing staked Ether (ETH). The conversion reduced the Ethereum network’s energy consumption by 99.9% instantly. Ethereum’s place as a number one programmable blockchain signaled industry-wide development to low-carbon-emission options.

Mohammed AlKaff AlHashmi, the co-founder of the Islamic Coin cryptocurrency, spoke with Cointelegraph about how the sector was evolving to cater to rising calls for.

“In 2022, inexperienced tasks observe three essential vectors. The primary is chopping their vitality consumption and emissions — similar to Ethereum lowering consumption by 99.9% and Polygon presenting itself as carbon-neutral. The second is ReFi — a brand new pattern of regenerative finance that experiments with monetary incentives to attract down carbon emissions.”

AlHashmi talked about that his community had adopted a brand new emission-reduction mannequin to realize its eco-friendly targets: “Within the case of Haqq [the blockchain that issues Islamic Coin], the protocol mechanically deposits 10% of the issued quantity right into a particular Evergreen DAO, a nonprofit digital basis centered on long-term sustainability and group influence.”

Dimitry Mihaylov, chief scientific officer at blockchain gaming metaverse Farcana, informed Cointelegraph that reducing emissions and on-chain transaction prices was good for the {industry} in the long run, as it will entice customers, traders, and governments.

“At present, a daily banking transaction consumes an order of magnitude much less electrical energy than a blockchain-based transaction, however we’re betting on the event of extra energy-efficient mining gear and quicker blockchain protocols. If profitable, ‘inexperienced’ crypto tasks are prone to obtain sturdy help from each governments and potential customers.”

That stated, 2022 noticed the rise of some distinctive, revolutionary, eco-friendly cryptocurrency tasks contributing to a greener world.

Chia Community

Chia Community takes a novel strategy to decrease carbon emissions by using a proof-of-space-and-time protocol that differs significantly from early energy-intensive crypto-mining mechanisms that require highly effective GPUs and processors. The community performs environment friendly transaction validations, also referred to as farming, and allocates customers’ empty pc space for storing into plots.

The method features via a decentralized community of nodes appearing as shoppers and servers connecting with their friends. The low processing energy necessities permit anybody with an honest spec pc to farm Chia (XCH) tokens.

The community depends on farmers to supply space for storing after which allocates mining privileges to every miner primarily based on randomly generated numbers assigned to every area. The space for storing whose saved numbers match carefully with these generated by the community wins mining privileges.

This algorithmic components rewards a higher allocation of random numbers to farmers with probably the most space for storing, creating extra successful probabilities.

XCH may be farmed utilizing a spread of infrastructures, together with cloud computing and information storage platforms similar to Amazon Internet Companies. Chia Community’s use instances embody help for decentralized finance tasks, asset tokenization platforms and decentralized exchanges.

On the vitality entrance, Chia Community claims to use about 0.12% of the annualized vitality utilized by the Bitcoin community. Whereas the idea is ingenious, it has drawbacks. Extra demand for onerous disk and strong state drives has emerged in international locations like China as a result of mining XCH wears out drives in as little as 40 days.

Regardless of this draw back, the community has introduced money-making alternatives for information storage suppliers with unused area and firms with worn however operational information storage {hardware} that’s now not in energetic use.


The Algorand blockchain community is built with an environmental focus and has made main strides towards changing into carbon-negative over the previous two years.

In 2021, Algorand partnered with ClimateTrade, a an organization that makes use of blockchain know-how to assist companies offset their carbon footprint, enabling them to trace their emissions in pursuit of broad sustainability objectives.

Associated: What is the Algorand blockchain, and how does it work?

The partnership enabled a portion of Algorand’s transaction charges to be put apart for buying the required carbon credit wanted to offset the community’s carbon footprint. Algorand is a proof-of-stake blockchain, making it extra vitality environment friendly than Bitcoin’s (BTC) proof-of-work consensus mechanism.

For perspective, one Bitcoin transaction consumes roughly 1,206.52 kilowatt-hours of electrical energy, whereas Algorand claims one transaction solely consumes about 0.000008 kWh of vitality.


Solana is a blockchain platform designed to host decentralized applications. It makes use of the PoS consensus mechanism to validate transactions and embodies the tenets of inexperienced token era. The platform can theoretically course of over 60,000 transactions per second. This eclipses the Bitcoin community, which processes seven transactions per second.

On-chain transactions are settled utilizing SOL (SOL) — the platform’s native cryptocurrency. The community has, since its inception, been working to realize carbon neutrality, and it reached the milestone for the primary time in 2021 by becoming a member of a carbon offset program.

Earlier this 12 months, Solana received a favorable carbon rating from the Crypto Carbon Rankings Institute (CCRI) for consuming the bottom vitality at a price of 0.166 watt-hours per transaction.

Whereas many blockchain networks use the energy-efficient PoS consensus mechanism, Solana’s effectivity is boosted by one other novel mechanism known as proof-of-history (PoH). With PoH, a timestamp creates a historic document to show an occasion has occurred at a selected time. The nifty, pioneering answer permits the community to concentrate on validating present transactions with out having to reference previous temporal claims by nodes.

This permits consistency, as nodes should abide by set transaction ordering. The method permits the protocol to be quick and vitality environment friendly.


Avalanche is a blockchain platform that aims to address the blockchain trilemma of scalability, effectivity, and safety by utilizing its distinctive proof-of-stake consensus mechanism. The platform makes use of its native AVAX (AVAX) token to facilitate transactions and distribute system rewards.

Avalanche has been lauded as one of the vital energy-efficient chains in 2022. Based on a analysis examine by the CCRI, the Avalanche public blockchain consumed about 0.0005% of the quantity of vitality utilized by the Bitcoin community, which is fairly spectacular.

These and different high-efficiency properties have made Avalanche the platform of choice for tasks with environmental issues.

The way forward for eco-friendly crypto tasks

Eco-friendly cryptocurrency tasks are right here to remain. They’re designed to be extra environmentally sustainable and have gotten more and more widespread amongst customers resulting from their scaling capabilities and decrease fuel charges.

The advantages they supply will doubtless result in the event of extra environmentally pleasant blockchains whereas encouraging the enhancement of present ones. That stated, 2022 sits on the cusp of a brand new period the place inexperienced crypto tasks develop into extra prevalent.
