Is Decentralized Finance just another trend?

Have you been hearing about Decentralized Finance and wondered what it really is? Why has it become so popular? On our Nextrope blog, we break down the technology to decipher its constituents and understand what makes it tick. We compare it to Centralized Finance (the current status quo) and see how it holds up.

Why fix something not broken – Centralized Finance vs Decentralized Finance?

Humans have always had a centralized authority directing and regulating the way they earn and spend money. The norm is that a central mint prints and distributes money, the central bank lends to other banks who then lend to their customers, and these customers deposit their savings back into the banks. It has worked for hundreds of years. Why then do we feel like we need an alternative? Why is Decentralized Finance (DeFi) trending? The simple answer is that Centralized Finance (CeFi) has always had glaring problems, but most chose to ignore it since there was no other alternative at hand. With the introduction of distributed ledger technology (blockchain), this is no longer the case. Decentralized Finance has finally become a reality, albeit with drawbacks of its own.

Whenever power, especially financial power, is centralized, most people get locked out of the decision-making process. Consequently, only a small portion of the population reap the benefits of the financial system while the rest are charged exorbitant fees, high interest rates and low returns. Even in the US, only 7% of the bottom 80% of society own shares in companies, whereas in other nations, most do not even have access to stock markets. Currently, transferring money outside of the country involves countless middlemen and substantial fees, obtaining a loan is met with walls of red tape and bureaucracy and the interest rates on deposits is often abysmal.

Even the safety factor that was attributed to banks eroded after the 2008 housing bubble. 2008 showed us that when few control all the money, risk accumulates at the center and endangers the entire system. In addition, banks use money in ways that most people don’t understand. In times of emergency, bank runs (many clients withdrawing their money from a bank) can quickly lead to zero cash balances, as seen in places like Argentina, Venezuela and Zimbabwe.

Is it surprising then that Bitcoin was first launched in 2009, a year after the financial crisis? There was a dire need for the first-ever solution to have global peer-to-peer settlements with no intermediaries required so that individuals could keep control over their assets. However, Bitcoin and early cryptocurrencies only decentralized the issuance and storage of money, not access to a broader set of financial instruments.

Decentralized Finance (DeFi) – the unlikely hero?

On paper, Decentralized Finance (DeFi) is disruption defined, allowing individuals full control and access over their assets. DeFi is an umbrella term referring to all the financial applications, such as lending, borrowing, exchanging, and investing which occur through decentralized channels and exchanges. The idea is to create an open-source, permissionless, and transparent financial service ecosystem available to everyone via peer-to-peer (P2P) capability, operating without any central authority. DeFi is distinct because it expands the use of blockchain from simple value transfer to more complex financial use cases such as borrowing, insurance etc. The activity in DeFi has increased exponentially in 2020 with total value locked in increasing from $1 Billion to $10 Billion in a span of 4 months.

As mentioned previously, DeFi is primarily being used for loans, trading and payments but there are additional use cases such as insurance and investing being developed. The Ethereum blockchain eco-system is the most popular for the development of these applications since it provides increased security, transparency, and growth opportunities. The Ethereum platform functions through ‘smart contracts’ which automatically executes transactions if certain conditions are met, removing the human element from all transactions.

While more and more people are being drawn to these DeFi applications, it’s hard to say where they’ll go. Much of that depends on who finds them useful and why. Many believe various DeFi projects have the potential to become the next Robinhood (popular online brokerage that enables stock trading at very low fees), drawing in hordes of new users by making financial applications more inclusive and open to those who don’t traditionally have access to such platforms.

DeFi’s not so shining armor

As with any new technology, there are growing pains. Some of the ones hurting DeFi particularly have been highlighted below:

1. Incomplete decentralization - Although protocols are decentralized and based on consensus algorithms, many access points to the system, like exchanges, are still centralized. In addition, many crypto projects are managed through centralized organizations or companies that too often lack transparency or accountability, and do not openly show the development of new parts of the ecosystem.

2. Volatility - Many DeFi applications, such as meme coin YAM, have crashed and burned, sending the market capitalization from $60 million to $0 in 35 minutes. Other DeFi projects, including Hotdog and Pizza, faced the same fate, and many investors lost a lot of money.

3. Security – While there are no humans involved in the smart contract process, humans do create the contracts and that is a major source of errors. Smart contracts are powerful, but they can’t be changed once the rules are baked into the protocol, which often makes bugs permanent and increases risk.

4. Rising Network fees – Network usage is directly correlated with fees and due to the recent popularity of DeFi, the Ethereum fees have sky-rocketed. This has led to a decrease in profitability for DeFi users and is hindering user experience.

5. Risk of Fraud – While smart contracts have no human involvement in its execution, there are humans involved in its coding. This vulnerability leaves the door open for errors and subsequent attacks on the network.

Conclusion

Decentralized Finance is still at its nascent stage and is still trying to find solid ground beneath its legs. Blockchain and cryptocurrency enthusiasts seem to think there is enormous potential and have therefore poured significant sums of money into various DeFi platforms. Given the multiple challenges DeFi currently faces, worse comes to worst, it will at least force the centralized system to become more competitive by introducing changes to their structure.

Token Engineering Process

Kajetan Olas

13 Apr 2024
Token Engineering Process

Token Engineering is an emerging field that addresses the systematic design and engineering of blockchain-based tokens. It applies rigorous mathematical methods from the Complex Systems Engineering discipline to tokenomics design.

In this article, we will walk through the Token Engineering Process and break it down into three key stages. Discovery Phase, Design Phase, and Deployment Phase.

Discovery Phase of Token Engineering Process

The first stage of the token engineering process is the Discovery Phase. It focuses on constructing high-level business plans, defining objectives, and identifying problems to be solved. That phase is also the time when token engineers first define key stakeholders in the project.

Defining the Problem

This may seem counterintuitive. Why would we start with the problem when designing tokenomics? Shouldn’t we start with more down-to-earth matters like token supply? The answer is No. Tokens are a medium for creating and exchanging value within a project’s ecosystem. Since crypto projects draw their value from solving problems that can’t be solved through TradFi mechanisms, their tokenomics should reflect that. 

The industry standard, developed by McKinsey & Co. and adapted to token engineering purposes by Outlier Ventures, is structuring the problem through a logic tree, following MECE.
MECE stands for Mutually Exclusive, Collectively Exhaustive. Mutually Exclusive means that problems in the tree should not overlap. Collectively Exhaustive means that the tree should cover all issues.

In practice, the “Problem” should be replaced by a whole problem statement worksheet. The same will hold for some of the boxes.
A commonly used tool for designing these kinds of diagrams is the Miro whiteboard.

Identifying Stakeholders and Value Flows in Token Engineering

This part is about identifying all relevant actors in the ecosystem and how value flows between them. To illustrate what we mean let’s consider an example of NFT marketplace. In its case, relevant actors might be sellers, buyers, NFT creators, and a marketplace owner. Possible value flow when conducting a transaction might be: buyer gets rid of his tokens, seller gets some of them, marketplace owner gets some of them as fees, and NFT creators get some of them as royalties.

Incentive Mechanisms Canvas

The last part of what we consider to be in the Discovery Phase is filling the Incentive Mechanisms Canvas. After successfully identifying value flows in the previous stage, token engineers search for frictions to desired behaviors and point out the undesired behaviors. For example, friction to activity on an NFT marketplace might be respecting royalty fees by marketplace owners since it reduces value flowing to the seller.

Design Phase of Token Engineering Process

The second stage of the Token Engineering Process is the Design Phase in which you make use of high-level descriptions from the previous step to come up with a specific design of the project. This will include everything that can be usually found in crypto whitepapers (e.g. governance mechanisms, incentive mechanisms, token supply, etc). After finishing the design, token engineers should represent the whole value flow and transactional logic on detailed visual diagrams. These diagrams will be a basis for creating mathematical models in the Deployment Phase.

Objective Function

Every crypto project has some objective. The objective can consist of many goals, such as decentralization or token price. The objective function is a mathematical function assigning weights to different factors that influence the main objective in the order of their importance. This function will be a reference for machine learning algorithms in the next steps. They will try to find quantitative parameters (e.g. network fees) that maximize the output of this function.
Modified Metcalfe’s Law can serve as an inspiration during that step. It’s a framework for valuing crypto projects, but we believe that after adjustments it can also be used in this context.

Deployment Phase of Token Engineering Process

The Deployment Phase is final, but also the most demanding step in the process. It involves the implementation of machine learning algorithms that test our assumptions and optimize quantitative parameters. Token Engineering draws from Nassim Taleb’s concept of Antifragility and extensively uses feedback loops to make a system that gains from arising shocks.

Agent-based Modelling 

In agent-based modeling, we describe a set of behaviors and goals displayed by each agent participating in the system (this is why previous steps focused so much on describing stakeholders). Each agent is controlled by an autonomous AI and continuously optimizes his strategy. He learns from his experience and can mimic the behavior of other agents if he finds it effective (Reinforced Learning). This approach allows for mimicking real users, who adapt their strategies with time. An example adaptive agent would be a cryptocurrency trader, who changes his trading strategy in response to experiencing a loss of money.

Monte Carlo Simulations

Token Engineers use the Monte Carlo method to simulate the consequences of various possible interactions while taking into account the probability of their occurrence. By running a large number of simulations it’s possible to stress-test the project in multiple scenarios and identify emergent risks.

Testnet Deployment

If possible, it's highly beneficial for projects to extend the testing phase even further by letting real users use the network. Idea is the same as in agent-based testing - continuous optimization based on provided metrics. Furthermore, in case the project considers airdropping its tokens, giving them to early users is a great strategy. Even though part of the activity will be disingenuine and airdrop-oriented, such strategy still works better than most.

Time Duration

Token engineering process may take from as little as 2 weeks to as much as 5 months. It depends on the project category (Layer 1 protocol will require more time, than a simple DApp), and security requirements. For example, a bank issuing its digital token will have a very low risk tolerance.

Required Skills for Token Engineering

Token engineering is a multidisciplinary field and requires a great amount of specialized knowledge. Key knowledge areas are:

  • Systems Engineering
  • Machine Learning
  • Market Research
  • Capital Markets
  • Current trends in Web3
  • Blockchain Engineering
  • Statistics

Summary

The token engineering process consists of 3 steps: Discovery Phase, Design Phase, and Deployment Phase. It’s utilized mostly by established blockchain projects, and financial institutions like the International Monetary Fund. Even though it’s a very resource-consuming process, we believe it’s worth it. Projects that went through scrupulous design and testing before launch are much more likely to receive VC funding and be in the 10% of crypto projects that survive the bear market. Going through that process also has a symbolic meaning - it shows that the project is long-term oriented.

EVM-Compatible vs EVM-Equivalent

EVM-Compatible

EVM compatibility means a blockchain can interact with Ethereum's ecosystem to some extent. It can interact supporting its smart contracts and tools but not replicating the entire EVM environment.

EVM-Equivalent

An EVM-equivalent blockchain, on the other hand, aims to fully replicate Ethereum's environment. It ensures complete compatibility and a smooth transition for developers and users alike.

Berachain's Position

Berachain can be considered an "EVM-equivalent-plus" blockchain. It supports all Ethereum operations, tooling, and additional functionalities that optimize for its unique Proof-of-Liquidity and abstracted use cases.

Berachain Modular First Approach

At the heart of Berachain's development philosophy is the Polaris EVM framework. It's a testament to the blockchain's commitment to modularity and flexibility. This approach allows for the easy separation of the EVM runtime layer, ensuring that Berachain can adapt and evolve without compromising on performance or security.

Proof Of Liquidity Overview

High-Level Model Objectives

  • Systemically Build Liquidity. By enhancing trading efficiency, price stability, and network growth, Berachain aims to foster a thriving ecosystem of decentralized applications.
  • Solve Stake Centralization. The PoL consensus works to distribute stake more evenly across the network, preventing monopolization and ensuring a decentralized, secure blockchain.
  • Align Protocols and Validators. Berachain encourages a symbiotic relationship between validators and the broader protocol ecosystem.

Proof-of-Liquidity vs Proof-of-Stake

Unlike traditional Proof of Stake (PoS), which often leads to stake centralization and reduced liquidity, Proof of Liquidity (PoL) introduces mechanisms to incentivize liquidity provision and ensure a fairer, more decentralized network. Berachain separates the governance token (BGT) from the chain's gas token (BERA) and incentives liquidity through BEX pools. Berachain's PoL aims to overcome the limitations of PoS, fostering a more secure and user-centric blockchain.

Berachain EVM and Modular Approach

Polaris EVM

Polaris EVM is the cornerstone of Berachain's EVM compatibility, offering developers an enhanced environment for smart contract execution that includes stateful precompiles and custom modules. This framework ensures that Berachain not only meets but exceeds the capabilities of the traditional Ethereum Virtual Machine.

CometBFT

The CometBFT consensus engine underpins Berachain's network, providing a secure and efficient mechanism for transaction verification and block production. By leveraging the principles of Byzantine fault tolerance (BFT), CometBFT ensures the integrity and resilience of the Berachain blockchain.
