Authorization and Identity: Chainlink Use Cases

Chainlink stands at the forefront of enhancing security and compliance within smart contract-enabled blockchain networks. By enabling direct access to real-world data, Chainlink ensures that blockchain applications can operate with the same level of trust and verification as traditional systems. This integration is crucial for a wide range of applications, from financial services requiring Know Your Customer (KYC) and Anti-Money Laundering (AML) compliance to any form of digital agreement that needs to securely verify the identity of parties involved.

What is Chainlink

Overview

Chainlink is a decentralized oracle network that plays a critical role in bridging the gap between smart contracts on blockchain networks and real-world data. It enables smart contracts to securely interact with external data.

  • Decentralized Data Oracles. Chainlink's network of decentralized oracles ensures that data fed into smart contracts is accurate and tamper-proof, mitigating risks associated with relying on a single data source.
  • Smart Contract Connectivity to Real-World Data. It facilitates the seamless integration of external data sources, such as financial market data, weather information, and much more, enabling smart contracts to execute based on inputs from the real world.
  • Chainlink VRF (Verifiable Random Function). This feature provides a secure and provably fair source of randomness for blockchain applications, crucial for gaming, NFTs, and any application requiring random number generation.

When it comes to authorization and identity verification, Chainlink's role becomes even more crucial. By connecting smart contracts with external data sources, such as governmental identity databases or digital identity verification services, Chainlink enables the creation of blockchain applications that require verified human identities. This capability is essential for applications that must adhere to regulatory standards or for those seeking to mitigate the risk of fraud.

Moreover, Chainlink's decentralized nature ensures that the process of identity verification is not only secure but also resistant to manipulation. By leveraging multiple independent oracles to fetch and validate data before it's provided to a smart contract, Chainlink ensures a level of reliability and trustworthiness that centralized data sources cannot match. This decentralized approach to authorization and identity verification opens up new possibilities for blockchain applications, making them more accessible, compliant, and secure for users around the globe.

The integration of Chainlink's decentralized oracle network into the domain of authorization and identity verification heralds a new era of security, efficiency, and compliance for blockchain applications. By leveraging real-world data and external verification services, Chainlink enables smart contracts to perform functions that were previously unthinkable in the blockchain space. Here, we explore several key use cases where Chainlink's technology significantly impacts authorization and identity verification processes.

E-Signatures

In the digital age, e-signatures have become the norm for legally binding agreements, eliminating the need for physical presence or paper-based documents. Chainlink oracles facilitate the integration of blockchain applications with leading e-signature providers like DocuSign. This integration ensures that e-signatures can be verified and recorded on the blockchain, providing immutable evidence of agreement and authorization. Furthermore, by enabling smart contracts to interact with e-signature solutions, Chainlink opens the door to automated contract execution based on the completion of digitally signed agreements, thereby streamlining business processes and reducing the time and cost associated with manual verification.

Biometrics for Smart Contract Authorization

Biometric verification offers a high level of security and convenience for identity verification. It leverages unique physical characteristics such as fingerprints or retinal patterns. This use case is particularly relevant for access control systems and secure transactions. It also helps with identity verification processes that require a high degree of trust and security. By connecting smart contracts with biometric databases, blockchain applications can achieve a new level of security and fraud prevention.

Credential Verification

Credential verification is crucial in numerous applications, from financial transactions requiring proof of funds to access systems demanding specific security clearances. Chainlink oracles play a pivotal role by securely relaying credential verifications from external systems to the blockchain. This capability allows smart contracts to automatically verify users' credentials in real-time, facilitating seamless transactions and interactions that require verified identity or authorization credentials. For example, a decentralized finance (DeFi) platform can use Chainlink to verify a user's creditworthiness or asset ownership before allowing them to participate in lending or borrowing services.

Social Media Identity and Domain Names

The integration of social media identities with blockchain applications enhances user experience by providing more intuitive and human-readable identifiers, such as domain names or social media handles. Chainlink oracles facilitate this by securely linking off-chain social media identities to on-chain addresses or domain names. This use case not only improves the usability of blockchain applications but also adds an extra layer of verification, as users can easily confirm the authenticity of the parties they are interacting with.

Chainlink Twitter

Intellectual Property Management

Chainlink's decentralized oracle network enables smart contracts to interact with external IP databases for verifying ownership. This application is particularly useful for copyright and trademark management, patent licensing, and royalty distribution. By automating IP verification and transactions through Chainlink, creators and owners can more efficiently manage their rights and receive payments, while users gain access to verified IP assets.

Contribution Bounties in Open Source Projects

Open-source projects can leverage oracles to automate the verification of contributions and the distribution of bounties. By connecting smart contracts with public code repositories like GitHub, Chainlink allows projects to automatically track contributions, verify the fulfillment of predefined conditions, and release payments to contributors. This application streamlines the contribution process, incentivizes open-source development, and ensures that contributors are fairly compensated for their work.

Chainlink Identification Verification

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.
