Blockchain 101 - Assets, Transactions, and Hashes

In the previous chapters, you read two executive summaries that introduced the world of blockchain and the effects that it can have on you as an Oracle developer or customer. In Part II, we will cover the architectural building blocks of a blockchain.

In this chapter, we will look at the fundamentals that make up the blockchain technology, which include assets, transactions, and hashes. You will learn about the following topics:

• What are transactions, and how does a blockchain deal with transactions?
• How are transactions managed in a blockchain network?
• What is the general structure of a transaction, and how can we send them?
• How are transactions signed so that we can assume they are not compromised?
• Which hash functions are used by a typical blockchain?
