Smart contracts are secure, self-executing digital contracts. They are being used more frequently to manage a variety of tasks, such as money transfers and property transfers. Smart contracts have a lot of advantages, but they also carry a lot of risk. Therefore, before deployment, a smart contract audit is essential. In this article, we'll go through why it's important to audit smart contracts, how to choose a smart contract auditor, and how to streamline the auditing procedure.

Introduction to Smart Contracts

Smart contracts have grown in popularity as a safe and open way to manage agreements and transactions. Smart contracts are digital contracts that are maintained on a blockchain and executed automatically when specific circumstances are satisfied. These agreements can be used for a variety of transactions, including as the trading of goods and services as well as the transferring of rights and ownership. Although smart contracts provide a number of advantages, including security, transparency, and immutability, it is essential to carry out an audit before deploying them in order to guarantee their dependability and security.

Why is Auditing Smart Contracts Important

Blockchain smart contracts must be audited in order to find and fix any potential flaws or mistakes before they are put into use. A smart contract that has been stored on the blockchain cannot be changed after that point because it is a decentralized and immutable record. Any defects or weaknesses in a smart contract could have severe repercussions, including monetary losses, legal troubles, or reputational harm. Therefore, before a smart contract is implemented, it must undergo an audit to confirm its security and dependability. In order to guarantee smart contracts' ongoing security and dependability when changes are made, it is also advisable to audit them frequently.

What is a Smart Contract Audit?

An audit of a smart contract's code is done systematically to look for any vulnerabilities or defects that might exist. A certified smart contract auditor who is proficient in the programming language used to create the contract does this process. In order to find any problems like wrong grammar, faulty logic, or insufficient security measures, the auditor thoroughly examines the code line by line during the audit. The audit also seeks to locate any malware or other potential security risks in the contract. The auditor then submits a report detailing their findings and recommendations for improvement.

Benefits of a Smart Contract Audit

The advantages of auditing smart contracts are numerous. It aids in making sure the contract is trustworthy and safe, which can lower the chance of monetary losses, legal problems, and reputational harm. Additionally, it assists in ensuring that the contract complies with current laws and norms.

Smart contract auditing enables the detection of possible problems before they have a chance to do much harm. This can assist in lowering the price of any necessary repairs or modifications. As any possible problems may be rapidly detected and fixed, it can also aid in reducing the amount of time required to deploy the contract.

What to Look for in a Smart Contract Auditor

Look for someone with experience and expertise when choosing a smart contract auditor. The auditor should be knowledgeable with the best practices for auditing smart contracts and have a thorough understanding of the coding language used to develop the contract.

Additionally, the auditor needs to be familiar with the particular platform that was used to draft the contract. For instance, the auditor needs to be familiar with the Ethereum Virtual Machine if you're using it. This will help to guarantee that the audit is thorough and correct.

The Process of Auditing Smart Contracts

Smart contract auditing often entails a more in-depth and exhaustive examination of the code. The following steps may also be included in the process:

  1. Setting up a testing environment: In order to deploy and test the smart contract, the auditor must set up a testing environment. Installing the required software and equipment, such as a local blockchain network or an emulator, may be required to accomplish this.
  2. Examining the overall structure of the code: The auditor will examine the code's overall structure to make sure it is clear and ordered. They will also look for any coding best practices or standards that have been adhered to.
  3. Checking for any vulnerabilities in the code: The auditor will carefully study the code to look for any possible flaws or vulnerabilities that might be taken advantage of. This involves keeping an eye out for unsafe coding procedures like the usage of unsecure libraries or improper input validation.
  4. The contract will be put through its paces by the auditor to make sure it performs as planned and that all of its features and functions are operationally sound. Writing test cases or scenarios to put the functionality of the contract to the test may be required.
  5. Making recommendations: After the audit is finished, the auditor will deliver a report with their conclusions and suggestions. Any concerns that were discovered during the audit will be described in this report along with recommendations for how to deal with them. The report might also make suggestions for enhancing the contract's general stability and security.

Best Practices for Auditing Smart Contracts

In order to guarantee the security and dependability of blockchain-based applications, smart contracts must be audited. When auditing smart contracts, it's crucial to adhere to established practices for the best outcomes.

Utilizing a trustworthy auditor with experience and understanding is a crucial best practice. A competent auditor who is well-versed in smart contracts would be able to see possible problems and make insightful recommendations.

Making a thorough audit strategy before starting the audit is another crucial best practice. The audit's scope, the exact sections of the code that will be examined, and any testing that will take place should all be specified in this plan.

It's crucial to examine the code line by line during the audit to find any potential problems. To do this, you might check for erroneous logic, poor syntax, or missing security precautions. The auditor should also search for any potentially harmful code or security issues.

The auditor should deliver a thorough report detailing their findings and suggestions after the audit is finished. Any concerns that were discovered during the audit should be described in this report along with recommendations for how to deal with them. Additionally, suggestions for enhancing the contract's general stability and security should be included in the report.

It's critical to frequently check on the contract to make sure it's safe and trustworthy. To make sure the code is current with the most recent best practices and security precautions, this may entail running tests or reviewing it frequently.

Conclusion

An essential step in assuring the security and dependability of these contracts is smart contract audits. It is feasible to prevent damage and lower the cost of repairs or modifications by identifying potential weaknesses or vulnerabilities. It's crucial to take into account a smart contract auditor's level of experience and familiarity with the applicable platform when making your decision.

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.
