Developer Gospel: Tools and Resources brought by Ethereum Upgrade

Ethereum upgrade provides developers with rich tools and resources, significantly improving development efficiency and security. The mainstream development frameworks Hardhat and Truffle have been upgraded and the online development environment Remix IDE has been updated to better support new smart contract functions and EVM features. At the same time, the upgrade also provides new data and storage resources.

Ethereum upgrade has brought many tools and resources to developers, as follows:

Development Framework and Tools

• Hardhat and Truffle: These two mainstream development frameworks have been further optimized after the upgrade of Ethereum, and have better support for the new smart contract functions and Ethereum Virtual Machine (EVM) features. Developers can more easily develop, test and deploy smart contracts. For example, using Hardhat's plug-in system, it can easily integrate new upgrade functions and conduct more efficient development processes.
• Remix IDE: Online smart contract development environment Remix, after the upgrade of Ethereum, has updated support for new syntax and new features. Developers can directly write, debug and deploy smart contracts in the browser, without the need for complex local environment configuration, providing convenience for beginners and rapid iterative development.
• Ethereum storage tools: Storage such as MetaMask, the interaction with the Ethereum network is smoother and safer after upgrading. Developers can use them to test smart contracts, user authentication and digital asset management to provide users with a better experience.

Data and Storage Resources

• Beacon Chain Data LayerEthereum Shanghai upgraded to realize the connection between the beacon chain and the main chain, so that smart contracts on the main chain can access and use the data on the beacon chain. Developers can build more complex and efficient applications based on this, such as obtaining on-chain staking data, verifier information, etc., to provide richer data support for applications such as decentralized finance (DeFi), decentralized identity (DID).
• Temporary Data Blob: EIP-4844 in the Dencun upgrade introduces temporary data blobs as temporary storage units that store intermediate results during contract execution, helping to reduce the overall Gas cost when executing complex smart contracts. When developers process smart contracts with large-scale data and complex computing, they can use blobs to store temporary data to improve contract execution efficiency.

Interaction and Communication Resources

• Shash Chain Interaction Infrastructure: Shanghai upgraded to provide infrastructure for interaction between shard chains, and smart contracts on different shard chains can call and transmit information to each other. This provides developers with more space for collaboration and innovation, such as developing distributed applications across shards to achieve more efficient resource utilization and data interaction.
• Cross-chain bridge technology : Ethereum upgrade promotes bridging with other blockchain networks, making smart contracts on different blockchain networks compatible and interoperable. Developers can integrate applications on Ethereum with resources on other public chains, expand the boundaries and user groups of applications, and realize cross-chain asset transfer, data sharing and other functions.

Safety and Verification Tools

• Zero Knowledge Proof (SNARKs): In Ethereum upgrade, such as the "The Surge" upgrade stage, enhanced cryptography tools such as zero-knowledge proof are introduced to further improve the security and trust mechanism of the network 1. Developers can use zero-knowledge proof technology to build more secure smart contracts and applications, such as in privacy protection, identity verification and other scenarios to ensure the confidentiality and integrity of data.
• KZG Commitment: During the Dencun upgrade, KZG Commitment is used to protect the integrity of off-chain blob data. When dealing with off-chain data storage and verification, developers can use KZG's commitment to ensure data tamper-proof and trustworthiness and improve application security.
