What is Arbitrum?

As the blockchain technology landscape continues to expand and evolve, two major challenges remain prominent, particularly within the Ethereum network: scalability and transaction cost. In response to these issues, we find Arbitrum as a promising solution. So, what is Arbitrum?

Arbitrum is a Layer 2 scaling solution designed exclusively for the Ethereum network. Its core function involves processing the majority of transactions off the primary Ethereum chain (off-chain) and submitting a summarized version, or 'rollup,' of these transactions to the main chain. This approach significantly alleviates the burden on the main Ethereum chain, leading to faster transaction times and considerably reduced gas fees.

Analysis of Arbitrum

In today's dynamic blockchain environment, continuous development and growth are imperative. As platforms like Ethereum become increasingly popular, scalability emerges as a considerable challenge. This is where Arbitrum comes into play - a Layer 2 scaling solution aimed at addressing many of the limitations Ethereum currently experiences. So, what is Arbitrum, and why is it garnering such attention within the blockchain sphere?

The Origin Story

Arbitrum, created by Offchain Labs, emerged due to the rising need for a more efficient transaction process on the Ethereum blockchain. As user adoption and decentralized applications on Ethereum began to surge, it became evident that the existing network structure could not efficiently manage high volumes without exorbitant transaction fees or delayed transaction times.

Fundamental Idea and Methodology

At its foundation, Arbitrum employs something referred to as "Optimistic Rollups." What does this entail? Generally, rollups involve consolidating or "rolling up" numerous transactions into one which gets recorded on the main chain. This translates to less on-chain data, leading to faster and more affordable transactions.

The "Optimistic" component of Optimistic Rollups stems from its mechanism. Rather than verifying every individual transaction (a burdensome and time-consuming effort), Optimistic Rollups operate based on trust by presuming each transaction is legitimate. There's a catch though - if any transaction is discovered to be invalid, mechanisms exist to penalize those involved. This approach effectively maintains a balance between trust and validation while enabling faster transaction times without sacrificing security.

Arbitrum's Enhancement of Ethereum

Ethereum boasts a strong and groundbreaking foundation; however, its shortcomings in scalability are apparent. This is where Arbitrum steps in. By processing the bulk of transactions off-chain and only submitting crucial data to Ethereum's main chain, it substantially eases the burden on Ethereum in the following ways:

  • Faster Transactions: No more lengthy waits for transaction confirmations.
  • Lower Fees: Reduced on-chain data processing leads to substantially lower transaction costs.
  • Improved Scalability: this layer 2 solution can accommodate a greater volume of transactions simultaneously, making it suitable for extensive dApps and platforms.

Essentially, Arbitrum serves as a connection point, maximizing Ethereum's advantages while concurrently offering solutions to its limitations. As the cryptocurrency community progresses and expands, innovative technologies like Arbitrum will take center stage in shaping the decentralized landscape of the future.

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.
