Smart Contract: QA Role for Decentralized Platform

Presenter: Marco Andrade

This presentation has been developed to meet the growing need for blockchain-focused QA Engineers.

 

Everyone is talking about blockchain technology, especially in relation to smart contracts. Blockchain-related jobs are the second-fastest growing in today’s labor market; there are now 14 job openings for every one blockchain developer. And as Nick Szabo, the developer who coined “smart contracts,” pointed out, there is an extreme “$/knowledge” ratio in the blockchain space, where capital by far outpaces talent.

 

But where are all the QA engineers? It’s unacceptable to see projects gone live with little or no testing by anyone other than the dApp developer. We all know what happens when we combine new technology with a lack of formal QA… Bugs. Some could be minor, some can cause the loss of hundreds of thousands of dollars.

 

We will discuss the role of the modern tester and how it applies to the blockchain:

  • Testing tools
  • Examples of Smart Contract bugs
  • The differences between a hard fork, a soft fork, and a chain split
  • Forks and replay attacks
  • Benefits of splitting Smart Contracts into 2 portions: 1. Business logic contract; 2. Data Contract
  • Testing to optimize and minimize costs
