Web 3, also known as the "Semantic Web" or "Web 3.0," is a concept and vision for the future of the internet. It represents a paradigm shift from the current state of the web (Web 2.0) to a more intelligent, interconnected, and decentralized web. Web 3 is still a conceptual framework and a work in progress, but it's driven by several key principles and technologies.
Web 3 aims to make data more meaningful and accessible. This involves using semantic technologies like RDF (Resource Description Framework) and ontologies to make data and information machine-readable, allowing computers to better understand the context and relationships between different pieces of data.
Web 3 seeks to reduce the dominance of large corporations and centralized services. Blockchain and distributed ledger technologies play a significant role in enabling decentralized applications and services. These technologies enable trust and transparency without relying on a central authority.
Web 3 promotes interoperability between different services and platforms. This means that data and services can seamlessly interact and be used across different applications and websites, reducing data silos and improving the user experience.
Artificial intelligence and machine learning are integrated into Web 3 to enhance data analysis, search, and recommendation systems, making the web more intelligent and tailored to individual users.
Web 3 emphasizes user control over their data and privacy. Users are expected to have more control over how their data is collected, stored, and shared, with the ability to grant and revoke permissions as needed.
Through the use of cryptographic techniques and decentralized networks, Web 3 aims to enhance trust and security on the web. It reduces the reliance on centralized entities, making it more resilient to attacks and censorship.
Smart contracts, often associated with blockchain platforms like Ethereum, are a key feature of Web 3. They enable self-executing contracts with the terms of the agreement directly written into code. This can automate various processes and transactions.
Web 3 envisions users having more control over their data and the ability to monetize their data and digital assets directly, potentially creating new economic models.
Web 3 is still a vision and a work in progress, and its implementation faces various technical and regulatory challenges. However, it represents a shift towards a more open, decentralized, and user-centric internet where data is more meaningful, and individuals have greater control over their online experiences.
A DAO, or Decentralized Autonomous Organization, is an organization represented by rules encoded as a computer program that is transparent, controlled by the organization members and not influenced by a central government. DAOs are typically implemented on blockchain platforms and operate using smart contracts, which are self-executing contracts with the terms of the agreement directly written into code.
DAOs are built on blockchain technology, which provides a transparent and immutable ledger of all transactions and actions within the organization. This transparency is a fundamental aspect of their operation.
The rules and operations of a DAO are defined by code, typically in the form of smart contracts. These rules determine how decisions are made, how funds are managed, and how the organization operates.
In a DAO, decisions are often made collectively by its members, who hold tokens that represent their stake or voting power in the organization. Each member's influence is directly proportional to their holdings of these tokens.
DAOs aim to be autonomous entities, meaning they can operate without a central authority. Once the rules are set in the smart contract, the DAO can execute decisions and manage its resources automatically.
DAOs are often open for anyone to join, and membership is based on acquiring or staking tokens. This inclusiveness allows a diverse range of participants to have a say in the organization's decisions.
DAOs often manage resources, which can include cryptocurrencies, assets, or even intellectual property. Members of the DAO can vote on how these resources are allocated and used.
DAOs typically use voting mechanisms for decision-making. Members can submit proposals, and the community votes on whether to implement them. The weight of each member's vote is determined by the number of tokens they hold.
DAOs have been used for various purposes, including decentralized finance (DeFi), governance of blockchain networks, investment funds, art collectives, and more. They offer a way to create organizations that are less reliant on traditional centralized structures, enabling more open and participatory decision-making.
However, it's essential to be aware of the potential risks and challenges associated with DAOs. These include issues with security (such as vulnerabilities in smart contracts), disputes within the community, and regulatory challenges. The most well-known case of a DAO, "The DAO," suffered a major hack in 2016, leading to a contentious hard fork of the Ethereum blockchain. This event highlighted the need for careful design, security, and governance in DAOs.
A non-fungible token (NFT) is a type of digital asset that represents ownership or proof of authenticity of a unique item or piece of content using blockchain technology. NFTs are distinct from cryptocurrencies like Bitcoin or Ethereum, which are fungible and can be exchanged on a one-to-one basis.
Each NFT is one-of-a-kind or represents a specific, distinguishable item. This could include digital art, collectibles, virtual real estate, in-game items, music, videos, virtual pets, and more. NFTs are often used to tokenize digital or digitizable assets.
NFTs are typically built on blockchain platforms, such as Ethereum, Binance Smart Chain, or Flow. These blockchains use smart contracts to manage NFTs, ensuring their scarcity and provenance.
NFTs cannot be divided into smaller units like cryptocurrencies. They are typically bought, sold, and owned as whole tokens.
One of the key features of NFTs is that they provide a transparent and immutable record of ownership and provenance. This means that the ownership history and origin of the NFT can be easily verified.
NFTs are often designed to be interoperable across different platforms and applications. This means that an NFT created in one application can be used or showcased in another, enhancing the value and utility of the digital asset.
NFTs are often associated with the concept of scarcity and rarity, which can make them highly sought after by collectors and enthusiasts. Creators can set specific parameters, such as the total supply of NFTs or the uniqueness of each item.
NFTs have gained significant attention in the worlds of art, entertainment, and gaming, and they are used to authenticate and trade digital content. They offer creators a new way to monetize their work, as NFTs can be sold in online marketplaces. Buyers acquire the NFT and, with it, ownership of the associated digital asset, along with the ability to resell it.
It's important to note that the NFT market is still relatively new and evolving, and there are debates and concerns regarding environmental impact (due to energy consumption in blockchain networks), copyright, and the speculative nature of NFT investments.
A smart contract is a self-executing contract with the terms of the agreement directly written into code. These contracts are stored on a blockchain and automatically execute when predefined conditions are met. Smart contracts enable trustless and automated transactions, removing the need for intermediaries, and making them a fundamental component of blockchain and cryptocurrency technologies.
Smart contracts are composed of code that defines the rules and conditions of the contract. These rules are typically written in a programming language that is supported by the specific blockchain platform on which the contract operates.
Once deployed on a blockchain, smart contracts automatically execute when the predetermined conditions are met. There is no need for manual intervention or third-party oversight.
Smart contracts, once deployed on a blockchain, are typically immutable, meaning they cannot be altered or tampered with. This immutability ensures that the contract's terms are not changed after deployment.
Smart contracts are executed on a decentralized network of nodes (computers) that validate and record transactions on the blockchain. This decentralization enhances security and trust.
Smart contracts operate in a trustless environment, meaning that participants in a contract do not need to trust each other or a third party. They trust the code and the blockchain's consensus mechanism.
Smart contracts are closely integrated with blockchain technology. They are often associated with platforms like Ethereum, which was the first to introduce the concept, but they can be implemented on various other blockchain platforms.
Smart contracts have a wide range of potential applications, including automated financial transactions (DeFi), supply chain management, digital identity verification, and more. They have the potential to streamline and automate various business processes.
In some cases, smart contracts rely on external information to execute. Oracles are used to feed real-world data into smart contracts. For instance, a smart contract for a weather-based insurance policy may need information about the weather conditions from an external oracle.
It's important to note that the term "smart contract" can be somewhat misleading, as these contracts are not necessarily "smart" in the way humans are. They simply execute predefined code when certain conditions are met. While they have the potential to increase efficiency and reduce the need for intermediaries, they are still reliant on accurate and secure programming and data inputs. Additionally, the legal enforceability of smart contracts may vary by jurisdiction, and they should not be confused with traditional legal contracts.
A digital wallet, often referred to as an e-wallet or electronic wallet, is a software application or digital tool that allows individuals to securely store, manage, and transact with various types of digital assets, including cryptocurrencies, traditional fiat currencies, payment cards, loyalty cards, and more. Digital wallets are used for a wide range of online and in-person transactions, offering convenience and security.
Digital wallets can store various types of digital assets, such as:
Digital wallets facilitate various types of transactions:
Digital wallets typically include security features such as encryption, biometric authentication (fingerprint or face recognition), PIN codes, and two-factor authentication (2FA) to protect the stored assets.
Digital wallets are available as mobile apps, desktop applications, web-based services, or hardware devices. Some wallets are specific to certain platforms or types of assets, while others offer multi-currency support.
Users are often encouraged to set up backup and recovery options to regain access to their wallet in case they lose their device or forget their credentials.
In the context of cryptocurrency wallets, the private keys that control access to your digital assets are typically stored within the wallet. Controlling your private keys is essential for security and ownership of your assets.
It's important to choose a digital wallet that suits your specific needs and the type of digital assets you intend to store and transact with. Security is a top priority when selecting a digital wallet, so be sure to research and choose a reputable wallet provider or app, and follow best practices for securing your wallet and assets.
DAO wallets are where the DAO receives its money, makes payments, or invests. You can call it the organization's bank account. All decisions, changes and use of funds are 100% transparent like everything else on the blockchain.
An Ethereum wallet is a digital tool that allows you to store, send, and receive Ether (ETH), which is the native cryptocurrency of the Ethereum blockchain. It also enables you to interact with decentralized applications (DApps) built on the Ethereum platform.
The primary purpose of an Ethereum wallet is to securely store your Ether. It does so by keeping track of your private and public keys. Your public key is your wallet address, which is visible to others and used for receiving Ether, while your private key is a secret code that should never be shared with anyone and is used to access and manage your Ether.
With an Ethereum wallet, you can send and receive Ether to and from other Ethereum addresses. To receive Ether, you share your public address with the sender, and to send Ether, you use your private key to sign the transaction.
Many Ethereum wallets support interactions with decentralized applications. These DApps can be related to decentralized finance (DeFi), non-fungible tokens (NFTs), games, and various other use cases. Your wallet allows you to authorize transactions and interact with these applications.
Security is a critical consideration when it comes to Ethereum wallets. There are different types of wallets, including software wallets (online, mobile, and desktop), hardware wallets, and paper wallets. Each offers varying levels of security. Hardware wallets are generally considered one of the most secure options because they store your private keys offline.
Ethereum wallets can be broadly categorized into the following types:
When choosing an Ethereum wallet, it's important to consider your security preferences, ease of use, and the features it offers. Ensure that you keep your private key safe and back up your wallet to prevent the loss of your Ether.

SAFT (Simple Agreement for Future Tokens) is often used as a fundraising tool for Web3 projects when tokens have not yet been issued, and the Token Cap Table has not yet been formed. At this stage, founders have only a rough understanding of the Token Cap Table, so SAFT usually indicates the relative size of the investor's token allocation (in percentages).
In instances where tokens have already been issued and there are plans to distribute further tokens from the investor pool, a Token Sale Agreement use be used. For both SAFT and Token Sale cases, founders need to conduct a detailed investor verification to meet AML requirements.
