Blockchain Scalability and its Foundations in Distributed Systems

Sydney examines why making a blockchain larger is a distributed-systems problem. Consensus and security provide the foundation for scalability questions. Although labeled beginner, the provider describes an audience with knowledge of graphs, sets and data structures.

What you will learn

• Explain the purpose of consensus.
• Relate security assumptions to system design.
• Analyze tradeoffs involved in blockchain scalability.

Who this suits

Learners with basic mathematics covering graphs and sets, plus data-structure knowledge, as specified by the provider.

Before you enroll

Separate the technical curriculum from claims about asset prices or investment returns. Platforms, security practices and regulation change, so check the age of examples. Use a local development environment or test network for exercises involving transactions.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Compare two fictional consensus designs and list the assumptions that affect their security and ability to scale.
