區塊鏈基礎課程概述
This first course of the Blockchain specialization provides a broad overview of the essential concepts
of blockchain technology – by initially exploring
the Bitcoin protocol followed by the Ethereum protocol – to lay the foundation necessary for developing applications and programming.
You will be equipped with the knowledge needed to create nodes
on your personal Ethereum blockchain, create accounts, unlock accounts, mine, transact,
transfer Ethers, and check balances.
You will learn about the decentralized peer-to-peer network,
an immutable distributed ledger and the trust model that defines a blockchain.
This course enables you to explain basic components of a blockchain (transaction,
block, block header, and the chain) its operations (verification, validation, and consensus model) underlying algorithms,
and essentials of trust (hard fork and soft fork). Content includes
the hashing and cryptography foundations indispensable to blockchain programming,
which is the focus of two subsequent specialization courses, Smart Contracts and Decentralized Applications (Dapps).
You will work on a virtual machine image, specifically created for this course,
to build an Ethereum test chain and operate on the chain.
This hands-on activity will help you understand the workings of a blockchain,
its transactions, blocks and mining.Main concepts are delivered through videos, demos and hands-on exercises.
智能合約課程概述
This second course of the Blockchain specialization will help you design, code,
deploy and execute a smart contract – the computational element of the blockchain technology.
Smart contracts allow for implementing user-defined operations of arbitrary complexity
that are not possible through plain cryptocurrency protocols. They allow users to implement conditions,
rules and policies of the domain applications. Smart contracts are a powerful feature that,
when properly designed and coded, can result in autonomous, efficient and transparent systems.
You will design and program smart contracts in Solidity language,
test and deploy them in the Remix development environment,
and invoke them from a simple web interface that Remix provides.
This course features best practices for designing solutions with smart contracts using Solidity and Remix IDE.
Main concepts are delivered through videos, demos and hands-on exercises.
去中心化應用 (Dapps)課程概述
This third course of the Blockchain specialization prepares
you to design and develop end-to-end decentralized applications (Dapps) – which provide anyone
with access to the blockchain’s features and services. You will use Truffle IDE,
smart contracts, a simple web client and a MetaMask client.
You will learn about the architecture of a Dapp: the front-end client interface,
backed by the blockchain and smart contracts. The course covers the basic design of a Dapp,
Truffle development process and commands (init, develop, test and migrate),
test-driven development of Dapp,
Dapp application models and emerging standards that are essential for predictable Dapp behavior.
Main concepts are delivered through videos, demos and hands-on exercises.
區塊鏈平臺課程概述
This fourth course of the Blockchain specialization provides learners
with an understanding of the broader blockchain ecosystem.
Learners are introduced to other blockchain platforms,
details of two decentralized application use cases, and challenges such as privacy and scalability.
They are prepared to discuss permissioned blockchain architectures
of Hyperledger and Microsoft Azure's blockchain as a service model
and analyze the Augur and Grid+ decentralized application platforms.
Course material includes emerging alternative decentralization models
such as IPFS and Hashgraph, challenges in broader blockchain adoption,
and continuous improvement solutions.
