What's inside Free Web3 Resources

  2. Overview of the LearnWeb3 educational platform

    LearnWeb3 is a free online educational platform designed for both new and experienced web2 developers to learn web3 technologies. The curriculum covers blockchain fundamentals, the development of decentralized applications (dApps), and the creation of smart contracts.

  3. Introduction to Solidity

    Solidity is a statically-typed, object-oriented, high-level language designed specifically for implementing smart contracts that target the Ethereum Virtual Machine (EVM). It uses a curly-bracket syntax and supports inheritance, libraries, and complex user-defined types. Solidity files use the .sol extension.

contract HelloWorld {
    string public greet = "Hello World!";
}

  5. Overview of the InterPlanetary File System (IPFS)

    IPFS is a peer-to-peer hypermedia protocol designed to make the web more resilient, open, and upgradeable. It aims to preserve and grow humanity's knowledge by decentralizing how content is addressed and stored across a network of nodes.

  6. Overview of Flux Oracle

    Flux is a trustless data layer and cross-chain oracle for web3. It enables smart contracts to access economically secure data feeds across various data sources and blockchain networks.

  7. Introduction to Push Protocol

    Push Protocol (formerly known as EPNS) is a decentralized notification protocol designed for Web3. In addition to notifications, it provides Push Chat, which enables secure, wallet-to-wallet messaging for users within the Web3 ecosystem.

  9. Overview of Polygon Blockchain Scalability Platform

    Polygon (formerly MATIC Network) is a blockchain scalability platform designed to address Ethereum's limitations, specifically high transaction fees, poor user experience, and low transaction throughput (TPS). It achieves this by providing a framework for Proof of Stake (PoS) transactions.

  10. Overview of Moralis Web3 APIs

    Moralis provides a suite of APIs to integrate blockchain data into any tech stack. Key API offerings include:

    • Web3 Data API: General scalable blockchain data access.
    • Streams API: Real-time on-chain event listening.
    • Authentication API: Wallet-based user authentication for backends.
    • EVM API: NFT, token, and transaction data for EVM-compatible chains.
    • Solana API: User and token data for the Solana blockchain.
    • NFT API: Real-time NFT transfers, prices, and metadata.
    • Token API: ERC20 token information across multiple blockchains.
    • Balance API: Native balance retrieval for specific wallet addresses.
    • Transaction API: Transaction data across multiple blockchains.
    • Events API: Contract logs and events across multiple blockchains.
    • Block API: Data on specific blocks across multiple blockchains.
    • DeFi API: Liquidity reserves and pair data across multiple blockchains.

  12. Overview of Swarm distributed storage

    Swarm is a distributed storage platform and content distribution service designed as a native base layer for the Ethereum web3 stack. It provides a decentralized and redundant storage solution for dapp code, user data, blockchain, and state data. Beyond storage, Swarm provides base layer services including node-to-node messaging, media streaming, decentralized database services, and scalable state-channel infrastructure for decentralized service economies.
