Overview of Web3
At a high level, Web3 aims to create a new iteration of the internet that is:
- Decentralized – Power and control are distributed, not concentrated in the hands of a few companies
- Open – Built on open-source protocols and software that anyone can use to build compatible applications
- User-centric – Users have ownership over their data and platform interactions
- Transparent – Transactions and interactions can be viewed publicly on the blockchain
This differs greatly from today’s internet (Web2) that is dominated by major tech platforms like Google, Facebook, and Amazon. Under the current model, these companies control most online activity from data to infrastructure.
Web3 shifts power back to individuals users through concepts like blockchain, cryptocurrency wallets, decentralized apps (dApps), decentralized storage systems, and decentralized autonomous organizations (DAOs). The result is an internet that is more secure, private, censorship-resistant, and peer-to-peer.
What are Web1 and Web2?
Web1 and Web2 refer to previous eras of the internet’s evolution:
Web1 (1980s – mid 1990s)
- Read-only, static web pages
- Very limited interactivity
- Early search engines and information portals
- Individuals mainly consumed rather than created content
Web2 (mid 1990s – present)
- Dynamic web applications
- Rise of social media, user-generated content, mobile apps
- Dominated by major centralized platforms like Google, Facebook, Amazon
- Huge amounts of data generated and monetized
- Shift towards user participation and interactivity
Web3 aims to build on Web2’s participatory aspects while decentralizing power away from big tech’s dominance over data, platforms, and economics. But it incorporates many of the technical innovations from the Web2 era like cloud computing and mobile access.
The evolution shows how the internet has progressively become more interactive, social, and decentralized from its initial roots as a read-only information network. Web3 represents the next stage in this evolution to create an internet that is open, transparent, interoperable, and user-owned.
What technologies support Web3?
Here are some of the key technologies that enable and support the development of Web3:
- Blockchain platforms – Such as Ethereum, Solana, Polkadot, Cosmos, etc. They provide the decentralized infrastructure for applications.
- Cryptocurrency protocols – Allow for creation and exchange of digital assets and currencies like Bitcoin, Ether, USDC.
- Decentralized storage – Filecoin, IPFS, Storj, Arweave enable distributed data storage.
- Decentralized identifiers (DIDs) – Enable user identity and data ownership without central authorities.
- Zero knowledge proofs – Allow validation of data without revealing contents, enhancing privacy.
- Oracles – Chainlink and others provide external data to blockchains.
- Layer 2 scaling – Solutions like Arbitrum and Optimism allow more complex dApps.
- Sidechains – Allow assets and data to be transferred between different blockchains.
- Decentralized cloud services – Provide computing resources like Dfinity and iEx.ec.
- Mesh networks – Allow peer-to-peer connectivity without ISPs like Althea Mesh.
- Crypto wallets – Enable users to safely access Web3 with non-custodial wallets.
- Decentralized VPNs – Encrypt network traffic without relying on VPN intermediaries.
- Virtual worlds – Web3-enabled metaverse platforms like Decentraland and The Sandbox.
This mix of protocols, infrastructure, and services collectively enable the decentralized web vision of Web3 to be realized.
How is Web3 different from Web2?
The core difference between Web2 and Web3 is the shift from centralized to decentralized control. In Web2, a few dominant platforms like Google, Facebook, and Amazon act as intermediaries that Web users must go through to access content and services. These companies centralize power and value creation.
Web3 utilizes new technologies like blockchain, cryptocurrency, and decentralized apps to remove intermediaries. Value accrues to networks of users rather than centralized platforms. Content, identity, payments, and infrastructure become open, transparent, and user-governed rather than controlled by corporate gatekeepers.
This shift promises to disrupt many digital industries. While Web2 democratized publishing and access to information, Web3 goes further to democratize ownership and economic participation online. Users can own assets, control identity, and collectively shape platform governance. Instead of handing over data to use free services, users can be compensated for their data and attention. Web3 puts users at the center rather than treating them as a product.
The core philosophies behind Web2 and Web3 internet models lead to profoundly different architectures and value distribution. Web3 aims to build a user-owned internet on open protocols and decentralized infrastructure.
In summary:
- Web2 concentrates power in large tech companies that control platforms and user data
- Web3 distributes power among users through open protocols, transparency, and token-based ownership models
- Where Web2 is closed, corporate, and centralized, Web3 aims to be open, community-driven, and decentralized
This shift to user-owned networks underpins the evolution from Web2 to Web3 models. However, in practice there is more of a continuum than a sharp divide between these web eras.
Key Components of Web3
Web3 is made up of several key components and technologies working together:
Blockchain
At the heart of Web3 is blockchain technology. A blockchain is a distributed digital ledger that records transactions in a verifiable and permanent way. Blockchains are the foundation for cryptocurrencies as well as smart contracts and other decentralized applications.
In Web3, blockchains allow digital assets and data to be stored and transacted without any central authority. Some of the most well-known blockchains used in Web3 projects include Ethereum, Solana, Polkadot, Cosmos, and Cardano.
Cryptocurrencies
Cryptocurrencies like Bitcoin and Ether provide the native currency used on blockchains. Cryptocurrencies allow for decentralized financial transactions and new economic models where users can pay for services directly without any intermediaries.
Wallets
Cryptocurrency wallets are software programs where users can store the private keys to their cryptocurrency holdings as well as interact with blockchain-based applications. Wallets are essential for accessing Web3 services and platforms.
Popular Web3 wallets include Metamask, Coinbase Wallet, WalletConnect, Slope, and Rainbow.
Decentralized Apps (dApps)
Decentralized apps (dApps) are applications built on top of blockchain networks. Because they eliminate centralized intermediaries, dApps allow users greater control over their data and digital assets.
Existing dApps cover areas like finance (lending, trading), gaming, identity systems, cloud storage, and more. dApps can also take the form of DAOs.
Decentralized Autonomous Organizations (DAOs)
DAOs are a new form of decentralized governance and organization. DAOs are community-led entities with rules encoded into smart contracts on the blockchain. This replaces the need for centralized management and creates a structure where decision-making power belongs to token holders.
Prominent DAOs include MakerDAO, AAVE, and dxDAO. DAOs manage collective resources from treasuries to protocols.
Decentralized Storage
Decentralized storage solutions allow data to be stored in a distributed network rather than centralized servers. This provides greater security, transparency, and user control. Projects like Filecoin, Storj, and Arweave enable decentralized storage for Web3 apps.
Oracles
Oracles are third-party services that provide external data to blockchains and smart contracts. This could include information like weather data, election results, sports scores, etc. Oracles are needed for many real-world use cases.
Chainlink is the most widely used oracle network for delivering data to different blockchains.
Consensus Mechanisms
Consensus mechanisms like proof-of-work and proof-of-stake are how blockchains can validate transactions and achieve agreement without a central party. These algorithms allow decentralized networks to ensure accuracy and security.
Bitcoin and Ethereum currently use proof-of-work while newer blockchains are transitioning to less energy-intensive methods like proof-of-stake.
Identity Management
Decentralized identity management gives users control over their digital identities and data. Rather than identities being tied to accounts on centralized platforms, Web3 identity systems use cryptography and blockchain to prove identity in a privacy-preserving and self-sovereign way.
SelfKey, Civic, and Blok are some of the major Web3 identity projects.
Key Benefits of Web3
The technologies and architecture behind Web3 aim to solve many of the problems associated with today’s centralized internet model. Some of the key benefits include:
- Reduced monopoly power – No single entity controls the entire ecosystem or can dominate markets through data monopolization.
- Censorship resistance – Content cannot be easily removed or blocked because there is no central platform regulating activity.
- Enhanced privacy – User data and identities are not controlled by third parties because interactions happen in a decentralized manner.
- True ownership – Users have actual ownership of digital assets verified on-chain rather than platform-dependent assets.
- Financial opportunity – New tokenized economic models powered by cryptocurrencies and DeFi allow wider participation.
- Transparency – All transactions and rules are recorded on public blockchains enabling accountability.
- Innovation – Open ecosystems fuel rapid innovation and collaboration rather than walled gardens.
- Accessibility – Everyone has permissionless access to the same underlying protocols to build or contribute.
What are some examples of Web3 in the real world?
Here are some real-world examples of Web3 applications and use cases:
- Cryptocurrency payments – Services like BitPay and Coinbase Commerce allow merchants to accept payment in crypto. This replaces traditional payment rails with decentralized blockchain transactions.
- NFT ticketing – Platforms like Yellowheart are selling event tickets as non-fungible tokens that provide proof of ownership on a blockchain. This prevents fraud and allows tickets to be resold peer-to-peer.
- Supply chain tracking – Businesses can track goods and inventory using the transparency of blockchains. For example, tracking the provenance of diamonds on a ledger.
- Decentralized storage – Filecoin and Storj allow users to rent out spare disk space in a decentralized manner rather than relying on centralized servers.
- DAO organization – Groups like MakerDAO and dxDAO have billions in assets under management while operating through decentralized governance models and proposal voting.
- Identity management – uPort and Civic allow users to control their identity via private keys instead of accounts on platforms. This maintains privacy while still allowing verification.
- Decentralized finance – Platforms like Uniswap and Aave have created an open financial system for trading, lending, and borrowing crypto assets without intermediaries.
- Non-fungible gaming – Games like Axie Infinity integrate blockchain to create scarce digital assets and provably rare game items.
- Metaverse spaces – Decentraland lets users buy virtual land NFTs and build immersive experiences owned and controlled by users rather than a platform.
These represent just some of the growing examples of Web3 adoption across industries.
