In an interview with crypto.news, Kadan Stadelmann, CTO of Komodo, describes the need to integrate sustainable practices and deflationary mechanisms to advance the blockchain industry while addressing environmental concerns.

Blockchain technology is at a crossroads where demand for sustainable tokenomics and is growing environmental awareness is reshaping the industry. As the world grapples with climate change, blockchain projects are innovating minimize your ecological footprint.

Deflationary mechanisms, like token burn, are not just financial instruments but are part of a broader strategy to create a greener and more sustainable economic model. It helps manage token supply, creating scarcity and attracting investors who prioritize value and long-term sustainability.

The industry’s focus on token sustainability and efficiency is setting new standards.

Stadelmann believes that the future of blockchain technology depends on the adoption of sustainable and deflationary tokenomics.

Considering the rapid evolution of tokenomic models, especially with the rise of deflationary mechanisms, how do these models influence the long-term value of tokens and investor behavior in the blockchain sector?

Tokenomic models, particularly those that incorporate deflationary mechanisms, have been influential in creating long-term value for cryptocurrency investors. On the other hand, projects that have inflationary tokenomics often create an environment that favors the creators or large holders of the cryptocurrency. Smaller holders, or people just discovering cryptocurrency, are at a disadvantage as they usually fail to accumulate enough supply to influence the market value. Furthermore, for centuries, we have seen the long-term negative effects of fiat currency inflation and hyperinflation in the global economy. Deflationary mechanisms such as block reward reduction (e.g. BTC) or token consumption (e.g. BNB) have historically led to an increase in the market value of cryptocurrencies.

Is Komodo making any moves in this regard?

Recently, the Komodo community has approved three proposals, two of which will lead directly to a more deflationary tokenomic model for KMD. These include KIP0002 (burning 100% of transaction fees and KIP0003 (reducing block reward from 3 KMD to 1 KMD). The other approved proposal – KIP0004 – will transition the Komodo blockchain from Proof of Work (PoW) to Proof of Stake (PoS) ) in 2025 or 2026 (exact date to be defined).

In terms of scalability and operational efficiency, what advantages does the model that supports independent blockchains for each project offer compared to traditional single-chain platforms?

The most important benefit of supporting a multi-chain model, rather than a single-chain model, is the autonomy of crypto projects to shape their own tokenomics. Projects that are based on Ethereum, for example, do not have the ability to reduce the underlying transaction fees (gas) on each transaction. Users must also hold ETH to pay for gas, even if their transaction does not otherwise involve ETH (e.g. exchanging one ERC-20 token for another ERC-20 token on a DEX). For cryptocurrencies that use their own blockchains, there is no need to charge a gas fee or rely on a secondary cryptocurrency. Projects can also set a minimum amount on transaction fees. Scalability is another factor. Since each cryptocurrency has its own blockchain, transaction completion times are generally much shorter due to less mempool congestion. Transaction fees are also typically much more consistent and cheaper.

What architectural innovations are currently leading the way in minimizing environmental impacts in the blockchain development industry? How do these technologies balance scalability with energy efficiency?

From the point of view of environmental sustainability, the biggest innovation is Proof of Stake. As we saw in September 2022, Ethereum’s move to Proof of Stake (PoS) reduced energy consumption by approximately 99.5% compared to Proof of Work (PoW). As a result, the network has also become more scalable. If we look at other PoS-based blockchains, on average they have a much higher transaction per second (TPS) limit than PoW-based blockchains. Another important aspect to consider is that PoS cryptocurrencies make it much easier for average, non-technical users to actively participate in network security and earn block rewards. This leads to higher participation among HODLers and creates a greater incentive to hold for a longer period of time than to sell during adverse market conditions.

How do deflationary strategies like token burning shape market dynamics and token valuation over time in the broader blockchain ecosystem?

It’s simple economics, or tokenomics in this case. In some cases, deflationary strategies such as token burn can contribute to price stability or mitigate downward pressure on prices. By reducing the supply of tokens, these mechanisms help counteract inflationary pressures that could otherwise devalue the token over time. This stability can boost investor confidence and attract more long-term investment. If demand for a specific cryptocurrency remains at least the same or increases over time, deflationary tokenomics should theoretically lead to an increase in prices.

What are the key architectural choices that can help blockchain platforms maintain high throughput and efficiency without compromising security or increasing costs?

There are several potential choices that can help crypto projects achieve high throughput and efficiency. While Proof of Work (PoW) often offers high-level security (especially for large blockchains like Bitcoin), it can be resource-intensive and limit throughput. Proof of Stake (PoS) and variants such as Delegation Proof of Stake (DPoS) offer higher throughput with lower resource requirements but require careful design to ensure security. Scaling solutions such as state channels (e.g. Lightning Network) or sidechains can enable off-chain transaction processing, reducing the load on the main blockchain and increasing throughput. However, they require careful integration with the main chain to maintain security and interoperability.

How crucial is it for blockchain platforms to keep transaction fees low?

The reality is that developers are more likely to rely on a blockchain that allows for cheaper transactions. As a result, users are also more likely to start using various dApps if they are convenient. Blockchains should allow developers to easily design smart contracts that minimize computational complexity and gas consumption. This is possible through techniques such as code optimization, gas-efficient data structures, and off-chain computing. Additionally, dApp developers should consider using pre-compiled contracts for computationally expensive operations.

From an industry-wide perspective, when designing blockchain solutions with a focus on environmental sustainability, what are some of the key considerations that developers should prioritize to ensure their platforms are efficient and have minimal impact?

As stated above, the simplest method is to use PoS. However, if PoW is necessary, consider implementing energy-efficient mining algorithms or variations that reduce computational workload and power consumption. Examples include Equihash (used in Zcash) or Ethash (formerly used in Ethereum). Operating nodes or mining farms prioritize energy-efficient hardware and data center practices. This includes using renewable energy sources and optimizing cooling systems to reduce energy waste. Another solution is to optimize the blockchain protocol and architecture for efficiency. This includes reducing block sizes, optimizing data storage and retrieval, and minimizing unnecessary computations. Efficient data structures and compression techniques can also help reduce your overall energy footprint.
