New Wave of Eco-Blockchains – why it matters and how you can act

The Blockchain community starts to notice the environmental impact of cryptocurrencies and distributed ledger technologies (DLT). Now, there is a new class of projects which combine sustainability and environment with decentralization, which augments their business utility. In this article, we explore the new wave of eco-blockchains, and why you should get on board quickly.

  • Proof of Work alternatives
  • Eco-friendly blockchains
  • How to lower the energy consumption of alternative finance
  • Blockchain and carbon neutrality

Though undoubtedly successful and enormously powerful, early Blockchain protocols such as the one of Bitcoin, have suffered from limitations to their scalability and sustainability. Because of their consensus mechanism in encrypting new blocks and adding them to the transaction ledger.

So far, the main race in blockchain technology has revolved around combating high transaction fees, boosting algorithm efficiency, and improving the speed of crypto transactions. Those factors have had a clear impact on crypto prices. 

Electricity consumption and carbon footprint

With the growth in the number of users and transactions, Blockchain systems based on the Proof-of-Work (PoW) mechanism require an increased computing power for miners. That causes increasingly-advanced computations to consume more energy as the network size grows. In turn, PoW-based Blockchains – such as the one of Bitcoin – have over time become environmentally unsustainable, because of their high energy consumption. Proof-of-Stake consensus model – e.g. in Ethereum – requires slightly less energy but does not eliminate the problem of limited scalability. 

Energy consumption

BTC alone represents 43% of the overall crypto traffic, which makes it the most popular cryptocurrency. The Bitcoin network has the greatest carbon footprint due to its energy consumption. According to the Bitcoin Energy Consumption Index, it’s estimated that Bitcoin mining requires 178 TWh of electrical power – roughly the same as the annual consumption of energy in Poland.  

Because of the environmental impact of mining, cryptocurrencies are criticized and compared to centralized financial tools. For example, one BTC creating a new block requires 1779 kWh of power, while 100,000 transactions operated by the payment card provider VISA, consume 189 kWh only. In one transaction, Bitcoin uses as much electricity as an average American household in 67 days. 

Eco blockchains - more sustainable future

Taking into account all the environmental considerations, the new generation of sustainable Blockchains has emerged in response to skyrocketing consumption of miners in conventional cryptocurrencies. Apart from ethical arguments, the reason for their rising popularity is scalability. With the rising prices of cryptocurrencies, miners need to process a greater volume of transactions; especially in 2021, the problem of rising electricity prices and power consumption became a pressing issue, making eco-friendly Blockchains not only an environmentally-sound proposition but also a very convincing use case in business. 

1. Chia - energy-efficient alternative

The Chia coin, powered by the Blockchain called Chia Network, skyrocketed in mid-2021 after its public mainnet launch. The Chia founder, Brian Cohen, is the author of popular software and protocol, BitTorrent. The platform was valuated at $500 million in a recent investment round. The Chia Network is currently the fastest-growing green Blockchain. It is also a smart transaction platform that allows users to take advantage of available hard drive space. Because Chia is also a smart contract platform, there is a new wave of further innovative projects released on the Chia Network that take advantage of carbon-neutral, scalable solutions of the space-based consensus mechanism. 

The Chia solution uses much less electricity compared to cryptocurrencies powered by PoW or the PoS consensus mechanism and allows more people to start mining at a lower cost. To become a Chia miner, one has to simply devote their disc space or use cloud computing platforms such as Amazon Web Services. Since Chia's launch in March 2021, Chia's computer memory usage has grown exponentially. While in mid-May 2021 it was about half a million terabytes of memory, in October this figure multiplied ten times. 

Unlike previous cryptocurrencies, the Chia coin is powered by a Blockchain using the Proof-of-Space-and-Time mechanism. As a result, Chia mining uses neither GPU nor CPU architecture to enable the exchange of data and value, but computer memory. Miners’ hard drive or SSD space powering the Chia Blockchain is connected to the decentralized network where storing a certain amount of data over a certain amount of time is rewarded in XCH, Chia’s token. 

Chia farming is accessible, with neither specialized equipment needed nor massive amounts of power. This makes it not The network’s blockchain transaction platform can be downloaded at chia.net. Users can decide to dedicate a portion of uncommitted hard drive space to the network and receive XCH in exchange, without significantly affecting computer performance or requiring vastly more energy.

2. SolarCoin 

Unlike Chia, which is a brand-new Blockchain and consensus mechanism, SolarCoin exploits the simple idea of smart contracts. It follows the logic of all other cryptocurrencies, but the key difference is that the platform design aims to incentivize real-world environmental activity: verifiably produced solar energy. The smart contract distributes 1 SolarCoin (SLR) for every MWh (megawatt hour) generated from solar panel technology. 

SolarCoin relies on two forms of Proof-of-Work (PoW) protocol. The first is the traditional cryptographic PoW associated with the most conventional cryptocurrencies (e.g. Bitcoin). The second-layer PoW is a verified mechanism that indicates whether the said 1 MWh of power was proved to be produced from solar energy. Then the smart contract distributes SolarCoins using these two PoWs as a means of rewarding green electricity generation.

3. IOTA

As a great add-on to IOTA’s tech proposition, its environmentally-oriented approach is achieved by eliminating miners, since they are the cause of environmental problems of cryptocurrencies.  IOTA uses an alternative to conventional Blockchain called the ‘Tangle’. Instead of mining, the network is maintained by smaller devices and uses calculations that require less power and thus consume less energy per transaction (0.00011 kWh per transaction), making it the most environmentally sustainable among the leading cryptocurrencies. 

The whole crypto community is getting green – so should you!

There are visible signs that the crypto developers are increasingly aware and active to find new ways of offering all the benefits of cryptocurrencies, with none of the unsustainable and environment-harming drawbacks. 

Leading Blockchain firms and corporations signed the Crypto Climate Accord. Its objective is to decarbonize the crypto industry and make it a net-zero greenhouse gas emitter by 2040. It was signed by such important names as Ripple, Consensys, Polygon – and among corporate giants: KPMG and NortonLifeLock.

Whether environmentally friendly by design or business choice, the crypto industry has very convincing arguments to ‘go green’. In the current form, the most popular cryptocurrencies like BTC have been heavily criticised for their unsustainability. Decentralization efforts cannot be sustained if the environmental costs of powering transactions keep rising. Hence, the rise of a new wave of green Blockchains and green cryptocurrencies a clear call to action for several stakeholders.

Given the early stage of development, environment-neutral cryptocurrencies and decentralized protocols are a great space for entrepreneurs to get involved. They can develop their own solutions based on sustainable Blockchains. Beyond optimizations in consensus mechanisms and DLT architectures, there are some of the most exciting business cases, such as green NFTs, exchanges and storage platforms.

Aethir Tokenomics – Case Study

Aethir Tokenomics – Case Study

Authors of the contents are not affiliated to the reviewed project in any way and none of the information presented should be taken as financial advice.

In this article we analyze tokenomics of Aethir - a project providing on-demand cloud compute resources for the AI, Gaming, and virtualized compute sectors.
Aethir aims to aggregate enterprise-grade GPUs from multiple providers into a DePIN (Decentralized Physical Infrastructure Network). Its competitive edge comes from utlizing the GPUs for very specific use-cases, such as low-latency rendering for online games.
Due to decentralized nature of its infrastructure Aethir can meet the demands of online-gaming in any region. This is especially important for some gamer-abundant regions in Asia with underdeveloped cloud infrastructure that causes high latency ("lags").
We will analyze Aethir's tokenomics, give our opinion on what was done well, and provide specific recommendations on how to improve it.

Evaluation Summary

Aethir Tokenomics Structure

The total supply of ATH tokens is capped at 42 billion ATH. This fixed cap provides a predictable supply environment, and the complete emissions schedule is listed here. As of November 2024 there are approximately 5.2 Billion ATH in circulation. In a year from now (November 2025), the circulating supply will almost triple, and will amount to approximately 15 Billion ATH. By November 2028, today's circulating supply will be diluted by around 86%.

From an investor standpoint the rational decision would be to stake their tokens and hope for rewards that will balance the inflation. Currently the estimated APR for 3-year staking is 195% and for 4-year staking APR is 261%. The rewards are paid out weekly. Furthermore, stakers can expect to get additional rewards from partnered AI projects.

Staking Incentives

Rewards are calculated based on the staking duration and staked amount. These factors are equally important and they linearly influence weekly rewards. This means that someone who stakes 100 ATH for 2 weeks will have the same weekly rewards as someone who stakes 200 ATH for 1 week. This mechanism greatly emphasizes long-term holding. That's because holding a token makes sense only if you go for long-term staking. E.g. a whale staking $200k with 1 week lockup. will have the same weekly rewards as person staking $1k with 4 year lockup. Furthermore the ATH staking rewards are fixed and divided among stakers. Therefore Increase of user base is likely to come with decrease in rewards.
We believe the main weak-point of Aethirs staking is the lack of equivalency between rewards paid out to the users and value generated for the protocol as a result of staking.

Token Distribution

The token distribution of $ATH is well designed and comes with long vesting time-frames. 18-month cliff and 36-moths subsequent linear vesting is applied to team's allocation. This is higher than industry standard and is a sign of long-term commitment.

  • Checkers and Compute Providers: 50%
  • Ecosystem: 15%
  • Team: 12.5%
  • Investors: 11.5%
  • Airdrop: 6%
  • Advisors: 5%

Aethir's airdrop is divided into 3 phases to ensure that only loyal users get rewarded. This mechanism is very-well thought and we rate it highly. It fosters high community engagement within the first months of the project and sets the ground for potentially giving more-control to the DAO.

Governance and Community-Led Development

Aethir’s governance model promotes community-led decision-making in a very practical way. Instead of rushing with creation of a DAO for PR and marketing purposes Aethir is trying to make it the right way. They support projects building on their infrastructure and regularly share updates with their community in the most professional manner.

We believe Aethir would benefit from implementing reputation boosted voting. An example of such system is described here. The core assumption is to abandon the simplistic: 1 token = 1 vote and go towards: Votes = tokens * reputation_based_multiplication_factor.

In the attached example, reputation_based_multiplication_factor rises exponentially with the number of standard deviations above norm, with regard to user's rating. For compute compute providers at Aethir, user's rating could be replaced by provider's uptime.

Perspectives for the future

While it's important to analyze aspects such as supply-side tokenomics, or governance, we must keep in mind that 95% of project's success depends on demand-side. In this regard the outlook for Aethir may be very bright. The project declares $36M annual reccuring revenue. Revenue like this is very rare in the web3 space. Many projects are not able to generate any revenue after succesfull ICO event, due to lack fo product-market-fit.

Quadratic Voting in Web3

Quadratic Voting in Web3

Decentralized systems are reshaping how we interact, conduct transactions, and govern online communities. As Web3 continues to advance, the necessity for effective and fair voting mechanisms becomes apparent. Traditional voting systems, such as the one-token-one-vote model, often fall short in capturing the intensity of individual preferences, which can result in centralization. Quadratic Voting (QV) addresses this challenge by enabling individuals to express not only their choices but also the strength of their preferences.

In QV, voters are allocated a budget of credits that they can spend to cast votes on various issues. The cost of casting multiple votes on a single issue increases quadratically, meaning that each additional vote costs more than the last. This system allows for a more precise expression of preferences, as individuals can invest more heavily in issues they care deeply about while conserving credits on matters of lesser importance.

Understanding Quadratic Voting

Quadratic Voting (QV) is a voting system designed to capture not only the choices of individuals but also the strength of their preferences. In most DAO voting mechanisms, each person typically has one vote per token, which limits the ability to express how strongly they feel about a particular matter. Furthermore, QV limits the power of whales and founding team who typically have large token allocations. These problems are adressed by making the cost of each additional vote increase quadratically.

In QV, each voter is given a budget of credits or tokens that they can spend to cast votes on various issues. The key principle is that the cost to cast n votes on a single issue is proportional to the square of n. This quadratic cost function ensures that while voters can express stronger preferences, doing so requires a disproportionately higher expenditure of their voting credits. This mechanism discourages voters from concentrating all their influence on a single issue unless they feel very strongly about it. In the context of DAOs, it means that large holders will have a hard-time pushing through with a proposal if they'll try to do it on their own.

Practical Example

Consider a voter who has been allocated 25 voting credits to spend on several proposals. The voter has varying degrees of interest in three proposals: Proposal A, Proposal B, and Proposal C.

  • Proposal A: High interest.
  • Proposal B: Moderate interest.
  • Proposal C: Low interest.

The voter might allocate their credits as follows:

Proposal A:

  • Votes cast: 3
  • Cost: 9 delegated tokens

Proposal B:

  • Votes cast: 2
  • Cost: 4 delegated tokens

Proposal C:

  • Votes cast: 1
  • Cost: 1 delegated token

Total delegated tokens: 14
Remaining tokens: 11

With the remaining tokens, the voter can choose to allocate additional votes to the proposals based on their preferences or save for future proposals. If they feel particularly strong about Proposal A, they might decide to cast one more vote:

Additional vote on Proposal A:

  • New total votes: 4
  • New cost: 16 delegated tokens
  • Additional cost: 16−9 = 7 delegated tokens

Updated total delegated tokens: 14+7 = 21

Updated remaining tokens: 25−21 = 425 - 21 = 4

This additional vote on Proposal A costs 7 credits, significantly more than the previous vote, illustrating how the quadratic cost discourages excessive influence on a single issue without strong conviction.

Benefits of Implementing Quadratic Voting

Key Characteristics of the Quadratic Cost Function

  • Marginal Cost Increases Linearly: The marginal cost of each additional vote increases linearly. The cost difference between casting n and n−1 votes is 2n−1.
  • Total Cost Increases Quadratically: The total cost to cast multiple votes rises steeply, discouraging voters from concentrating too many votes on a single issue without significant reason.
  • Promotes Egalitarian Voting: Small voters are encouraged to participate, because relatively they have a much higher impact.

Advantages Over Traditional Voting Systems

Quadratic Voting offers several benefits compared to traditional one-person-one-vote systems:

  • Captures Preference Intensity: By allowing voters to express how strongly they feel about an issue, QV leads to outcomes that better reflect the collective welfare.
  • Reduces Majority Domination: The quadratic cost makes it costly for majority groups to overpower minority interests on every issue.
  • Encourages Honest Voting: Voters are incentivized to allocate votes in proportion to their true preferences, reducing manipulation.

By understanding the foundation of Quadratic Voting, stakeholders in Web3 communities can appreciate how this system supports more representative governance.

Conclusion

Quadratic voting is a novel voting system that may be used within DAOs to foster decentralization. The key idea is to make the cost of voting on a certain issue increase quadratically. The leading player that makes use of this mechanism is Optimism. If you're pondering about the design of your DAO, we highly recommend taking a look at their research on quadratic funding.
