• 完成专项课程需要多长时间？

  Knowledge of at least one modern, high-level programming language is required. Learners should have an understanding of object-oriented design and programming, as well as the command line interface of a Linux-like system. This object-oriented knowledge is necessary for understanding and designing a smart contract. Basic working knowledge of web applications, HTML and javascript are necessary for developing Dapps. Also required is a laptop or a desktop of this specification: 64 bit machine with minimum 4Gb ram, 10Gb free space and Windows 7 or above , or ubuntu 16.04 or Mac os x 10.0+.

• Do I need to take the courses in a specific order?

  It is important that learners take the courses in order, since the concepts and projects are developed based on the previous course, as described below.

  · The first course focuses on essential concepts and does not require programming.

  · The second course explores the smart contract, gradually building the skills to program smart contracts in Solidity and test them using the Remix IDE. It features a programming project.

  · The third course drills deeper into developing end-to-end applications for the blockchain. It features interaction of a blockchain ecosystem with traditional web applications. Learners will develop applications and a project in the Truffle environment.

  · The fourth course introduces other blockchain platforms and business applications. Learners will compose a white paper that compares industry blockchain platforms.

• Will I earn university credit for completing the Specialization?

  No.

• 完成专项课程后我会获得大学学分吗？

  On completion of this specialization, a learner will recognize foundational concepts of blockchain, and apply these program concepts on the blockchain, including:

  · Algorithms and techniques enabling trust in a decentralized peer-to-peer network

  · Transactions, account, block and the structure of a blockchain

  · The distributed immutable ledger of transactions

  · Smart contracts, a core idea and computational model of blockchain that enables automation, autonomy, scalability and transparency

  · The blockchain application stack and orchestrating blockchain Dapp solutions for business use cases

  · Ongoing industry-wide blockchain efforts, such as Hyperledger (supply chain) and R3 Corda (financial)

  More specifically, on successful completion of the specialization, a learner will able to

  · Have an understanding and working knowledge of the emerging blockchain technology

  · Design and program smart contracts and decentralized application
