One more concern is that a reputation-based community may turn into a social credit system where people with higher ratings will get more benefits and others may get banned. This raises ethical questions and doesn’t give people a chance to improve.
Another method requires a person to choose a group of so-called guardians and give them the right to change their wallet keys by majority vote. What if a person loses contact with one of them or their relationship sours? This is life, anything can happen, so it will be difficult to entrust your Soul recovery to a group of people who may let you down, even if they did not do it intentionally.
The whitepaper by Vitalik Buterin, Glen Weyl, and Puja Ohlhaver suggests a number of methods to recover Souls, but those methods still need to be tried out and approved. For example, a community recovery model would require a member from a qualified majority of a (random subset of) Soul’s communities to consent when recovering a Soul’s private keys.
There are several concerns related to the possible implementation of soulbound tokens in the future, and the absence of 100% proven methods to recover lost Souls is one of them.
Enhance trust among members of the decentralized society
SBTs will provide DeSoc members with the means to check people’s reputations, so they will trust each other more than they would through casual interactions on social media or through digital projects.
Guarantee document authenticity
Digital verification and documentation will be typical features of soulbound tokens, to the benefit of both individuals and institutions. Your documents will be easy to store and take with you anywhere, and it will be faster for agencies to verify their authenticity.
Non-tradable and non-transferable
Compared to NFTs, which are easy to buy, collect, or hoard, SBTs don’t offer that. Why is this a benefit? Because soulbound tokens will require effort to get, and they will serve a more important purpose than just making money, such as building a person’s reputation and allowing them to take out loans and access specific projects.
Reduce dependence on centralized services
Currently, most of the services are centralized, which means that companies can access and collect our personal information for marketing and other purposes. With soulbound tokens, people have sovereignty over their data. It will be users themselves who manage their personal info and decide who can access it and for what reasons.
Reputation indicator
Soulbound tokens can also become an indicator of reputation on the Web3 network. People with a good reputation can help develop decentralized autonomous organizations (DAOs) that will be even more active in Web3. For example, people holding respectable SBTs can get majority votes to stand guard over the DAO’s integrity and protect the organization from bad actors.
Attendance verification
This use case is very similar to what a Proof of Attendance Protocol (POAP) offers these days. The difference is that the SBTs’ main purpose is to verify that the user actually attended an event and a POAP is an NFT that organizations use as part of their loyalty programs and marketing campaigns.
Digital ID and memberships
Users will also find it convenient to keep all their IDs inside one digital wallet instead of always having to carry a physical wallet full of cards.
Our IDs and membership cards can also be presented in the form of soulbound tokens. Gyms, sports clubs, libraries, and any kind of institution can issue SBTs to their members and enable them to store tokens in their wallets. In this way, people will have access to their data and visits and can keep these tokens for life.
Medical record management
It will be patients who have full control and access to their medical records, and they will be able to quickly verify their identity and share their medical history with doctors. This is especially important when the patient switches doctors and hospitals and seeks insurance. With SBTs, they won’t need to make hard copies of their papers. Instead, they will share (as well as revoke) access to their data with a few clicks.
When people seek medical help, the extra headache of finding a doctor, explaining their medical history, and dealing with an insurance company is not exactly what they need at that moment. If doctors and patients start using SBTs to store medical records, most of these problems can be avoided.
Credit reports
If a user needs to take out a loan, they can provide lenders with access to their credit profile that will be represented by SBTs. In this way, lenders will be able to quickly check the user’s credit history and approve the loan (or not, depending on how diligent the user has been in their previous payments).
Proof of professional skills
Soulbound tokens can represent a person’s credentials related to their educational and work background in Web3. These can be diplomas, professional certificates, work history, and resumes. All this data will allow a potential employer to see that all documents are verified and the applicant’s skills are therefore proved.
All in all, the adoption of SBTs is a logical step towards decentralization. And this is exactly what blockchain and Web3 are striving to do.
Users will not be able to sell their soulbound tokens or transfer them to another person. Thus, SBTs will not bring users any financial gain, but instead will help people protect their identities and give them maximum control over their personal data. In fact, the soulbound token holder will be able to control who is granted access to the data behind the token and can decide to revoke this access.
It’s important to note that soulbound tokens, just like NFTs, cannot be issued without a blockchain. They will forever remain there and will be tied to a specific user for life.
On the other hand, wallets are also called Souls. People can have numerous wallets, or Souls, that will safely store records from different areas of their lives such as education, medical history, work experience, and so on.
Before getting into how SBTs work, we should first find out how and by whom they can be created. The term associated with the process of issuing and storing personal records is called a Soul. This can be a company, an institution, or an entity. For example, you graduate from a university and receive your degree certificate. Your university, which will issue a digital certificate and a token, will be the Soul in this case.
Who
The idea of soulbound tokens and a decentralized society (DeSoc) governed by its users was described fully in a whitepaper by Vitalik Buterin, Glen Weyl, and Puja Ohlhaver published in May, 2022.
Ethereum Blockchain: NFTs are predominantly built on the Ethereum blockchain, utilizing its smart contract functionality to ensure ownership and traceability.
Early Adoption: NFTs first gained significant attention with the introduction of CryptoKitties in 2017.
Key characteristics
Programmability: Smart contracts enable additional functionalities such as royalties for creators.
Interoperability: NFTs can be bought, sold, and traded on various marketplaces.
Ownership: NFTs provide verifiable ownership and provenance.
Uniqueness: Each NFT is distinct and cannot be replicated.
Explanation: Unlike cryptocurrencies such as Bitcoin or Ethereum, which are fungible and can be exchanged on a one-to-one basis, NFTs are unique digital assets that represent ownership or proof of authenticity of a specific item or piece of content.
Definition: NFT stands for Non-Fungible Token.
Lending
Higher Rates than tradional banking
DeFi applications offer various financial services, such as lending, borrowing, and yield farming, without intermediaries.
DeFi aims to recreate traditional financial systems with decentralized, blockchain-based alternatives.
Decentralized Finance, or DeFi, is an emerging sector within the cryptocurrency ecosystem.
SHIB operates on the Ethereum blockchain and utilizes decentralized exchanges for trading.
It takes its inspiration from the Shiba Inu dog breed and aims to be the "Dogecoin Killer" by offering meme-inspired features and a community-driven ecosystem.
Shiba Inu Coin was created in 2020 as an experiment in decentralized community building.

Fraudulent shitcoins can lead to scams, financial losses, and reputational damage to the cryptocurrency industry.
Shitcoins can create market noise and distract investors from legitimate projects.
Shitcoins can also serve as experimental platforms for testing new ideas or technologies.
Some investors see opportunities for quick profits by trading shitcoins during periods of market volatility.
Poor community engagement: Legitimate cryptocurrencies usually have active and engaged communities, while shitcoins often lack genuine support.
Excessive marketing: Shitcoins may rely heavily on aggressive marketing tactics, promising unrealistic returns or exaggerated features.
Lack of transparency: Shitcoins often have limited information available about their team, technology, or roadmap.
It's crucial to differentiate between legitimate cryptocurrencies and shitcoins to make informed investment decisions.
Privacy and Confidentiality: Certain Layer 2 solutions on Ethereum can provide enhanced privacy features. They allow users to transact with a higher level of anonymity and confidentiality, ensuring that their financial activities are kept private. It's like wearing a mask or using a secret code when conducting financial transactions, protecting your identity and sensitive information.
Interoperability with Other Blockchains: Layer 2 solutions in Ethereum can also enable interoperability with other blockchains. Through mechanisms like cross-chain bridges, assets and data can be transferred between Ethereum and other blockchain networks, expanding the possibilities for decentralized finance (DeFi) and other applications. It's like having a bridge connecting two islands, allowing people and goods to move freely between them.
Improved User Experience: Layer 2 solutions aim to enhance the user experience by making transactions faster, cheaper, and more efficient. Users can interact with decentralized applications (DApps) on Layer 2 with near-instant transaction confirmations and minimal fees. It's like upgrading from a slow and expensive internet connection to a high-speed and affordable one, enabling smooth and seamless interactions with online services.
Lower Transaction Fees: Layer 2 solutions can also reduce transaction fees on the Ethereum network. Since some transactions are processed off-chain and settled on the Layer 1 blockchain later, it reduces the burden on the main network, resulting in lower fees for users. It's like getting a discount or a special offer when using a specific payment method, making transactions more affordable for everyone.
Scalability and Transaction Speed: One of the primary use cases of Layer 2 in Ethereum is to improve scalability and transaction speed. Ethereum's Layer 1 blockchain has a limited capacity to process a certain number of transactions per second. Layer 2 solutions, such as Optimistic Rollups or Plasma, help increase the network's capacity by moving some transactions off-chain. It's like having a highway with limited lanes, and Layer 2 solutions add extra lanes to accommodate more cars, reducing traffic congestion and allowing for faster transactions.
The EVM operates as a sandboxed environment, isolating the execution of smart contracts from the underlying computer system. It provides a secure and standardized environment where smart contracts can run without affecting the network's overall stability. Each node on the Ethereum network has its own instance of the EVM, ensuring that all computations and contract interactions are replicated across the network.
The EVM works by processing transactions and executing smart contracts on the Ethereum network. It functions as a decentralized virtual computer, capable of running complex computations across a network of distributed nodes. Smart contracts, written in Solidity or other Ethereum-compatible languages, are compiled into bytecode that the EVM can understand and execute. The EVM's consensus algorithm ensures the integrity and immutability of the executed code, making it a reliable and secure platform for decentralized applications.
The EVM is responsible for processing and executing smart contracts written in Ethereum's programming language called Solidity. It ensures that smart contracts are executed accurately and consistently across all participating computers (nodes) on the Ethereum network. The EVM also manages the allocation and distribution of Ethereum's native cryptocurrency, Ether (ETH).
The Ethereum Virtual Machine (EVM) is a crucial component of the Ethereum blockchain. It's a virtual machine, which means it's a software environment where smart contracts are executed. Smart contracts are self-executing agreements with predefined rules and conditions. The EVM enables the execution of these smart contracts on the Ethereum network.
This means that their mining equipment, specifically ASICs or GPUs, will no longer be needed for mining Ether.
