Ultimate Go: Advanced Engineering Episode 17

Introduction

In episode 16, Bill implemented additional means of verification for his blockchain’s transactions. The first update he made was to verify if a transaction is destined for his blockchain by reading the first byte of the signature. The next one Bill made was to recalculate the public address from a signature and compare it with the from field of the transaction to verify if the request is valid. While building this, Bill demonstrates how a user’s private key transforms into their public address.

In this video, Bill will begin to design the system that will track his blockchain’s account balances. He plans on building an accounting database that is stored entirely in memory. The first step Bill takes is to reuse a concept from the first segment of the series and leverage a memory pool as a means to store account balances. Watch and learn how to determine the account balances of the users on your blockchain.

Things you will learn in this video

  • How to determine a user’s account balance on the blockchain.
  • Implementing an in-memory database.

Go Training

We have taught Go to thousands of developers all around the world since 2014. There is no other company that has been doing it longer and our material has proven to help jump start developers 6 to 12 months ahead of their knowledge of Go. We know what knowledge developers need in order to be productive and efficient when writing software in Go.

Our classes are perfect for both experienced and beginning engineers. We start every class from the beginning and get very detailed about the internals, mechanics, specification, guidelines, best practices and design philosophies. We cover a lot about "if performance matters" with a focus on mechanical sympathy, data oriented design, decoupling and writing production software.
