Greenfield is a decentralized storage solution introduced by BNB Chain, designed to enhance data security, user autonomy, and storage efficiency. Leveraging blockchain technology, it enables users to manage, authorize, and trade data access rights seamlessly. With deep integration into BNB Smart Chain, Greenfield serves as a key infrastructure for DeFi and dApp ecosystems, playing a crucial role in advancing the Web3 landscape.
opBNB is a Layer 2 solution on BNB Smart Chain (BSC) powered by Optimistic Rollup technology. It aims to address the challenges of high transaction costs and network congestion in blockchain field. By handling most transactions on the Layer 2 network and batching them for final verification on the main chain BSC, opBNB delivers enhanced performance, reduced transaction fees, and outstanding scalability. Fully compatible with the Ethereum Virtual Machine (EVM), it allows developers to seamlessly migrate existing decentralized applications (DApps).
Ethereum is an open-source, decentralized blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (DApps). It was proposed by programmer Vitalik Buterin in 2013 and officially launched in 2015.
Mantle Network, an Ethereum layer-2 (L2) solution, is one of the fastest-growing Ethereum infrastructures. In this ecosystem, we will learn Solidity step by step from the basic syntax to advanced guided projects such as launching a token, an NFT, and “CryptoKitty”.
Telos is a high-performance, scalable Layer-1 blockchain using Delegated Proof of Stake (DPoS) consensus. It supports C++ and Solidity smart contracts, is EVM-compatible, and offers low-cost transactions and robust governance. Launched in 2018 with fair token distribution and no ICO, it aims to advance decentralized applications and the Web3 ecosystem.
OCID (Open Campus ID) is a decentralized identity solution at the heart of the Open Campus ecosystem, designed to empower learners with blockchain-based digital identity management. Built using Soulbound Tokens (SBTs) and Decentralized Identifiers (DIDs), OCID enables users to take full control of their academic achievements and personal data. It also integrates Verifiable Credentials (VCs), allowing achievements to be securely shared and verified across platforms.
Linea Network, an Ethereum layer-2 (L2) solution, is one of the most promising advancements in Ethereum's scalability landscape. In this ecosystem, we will start with a comprehensive introduction to the Linea ecosystem, progressing from basic Solidity syntax to advanced guided projects. Through this journey, you will develop skills to launch tokens, implement NFT Dutch Auctions, and build a decentralized social DApp. All projects can be deployed on the Linea Mainnet or Testnet, offering practical, hands-on experience within the Linea ecosystem.
Sonic is a high-performance network evolved from Fantom, aiming to address the blockchain “trilemma” of decentralization, security, and scalability. It achieves impressive performance with 10,000 TPS, sub-second finality, and transaction costs below $0.01. Additionally, Sonic introduces the innovative Fee Monetization (FeeM) mechanism, enhancing user experience and developer adoption, paving the way for the growth of decentralized ecosystems.
Open Campus is an innovative decentralized education ecosystem that leverages blockchain technology to connect learners, educators, content creators, and educational institutions, fostering collaboration and value creation. EDU Chain, consumer-facing education apps and on-chain education finance (EduFi), is built on the Open Campus platform. Here, you can Learn. Own. Earn.
