Solidity foundation - 1 Introduction to Solidity & Ethereum
What is blockchainA blockchain is a public database that is updated and shared across many computers in a network. Block refers to data and state being stored in consecutive groups known as blocks.If you send ETH to someone else, the transaction data needs to be added to a block to be successful. Chain refers to the fact that each block cryptographically references its parent.In other words, blocks get chained together.The data in a block cannot change without changing all subsequent blocks, ...

Arbitrum 引领牛市的四个角度
根据DefiLlama的数据，1月31日之后，Arbitrum的TVL超过Polygon位列第四，并在与其拉开差距，持续巩固这一地位。前段时间大火的Treasure DAO生态（magic、the beacon等）、费用一度超过以太坊的GMX都是该链上的项目。作为Layer 2中的代表，Arbitrum凭借技术和生态上的优势吸引了一众明星项目迁移过来，也进入了广大投资者的视野。1. 简介Arbitrum是基于以太坊的Layer 2扩容解决方案，平台宗旨是希望开发者能够在Layer 2上轻松运行EVM合约以及实现以太坊协议。作为Layer 2，由于原生token为ETH，所以Arbitrum可以在尚未发币的情况下先运行起来。从四象限图中可以看出，Arbitrum采用的方案是基于链上数据的欺诈证明1.1 团队背景开发团队Offchain Labs由前白宫技术官员、普林斯顿大学计算机教授 Ed Felten与普林斯顿计算机博士生Steven Goldfeder 、Harry Kalodner 联合创立。1.2 融资信息共完成3轮融资，总金额约145亿美元，投资方包括Pantera Ca...
