Just how do data miners pick up initiated transactions, order them, and verify them using Blockchain? Learn more about the work data miners do—and the very competitive races they run against each other—in this 8-video course, which begins by outlining the useful proof-of-work algorithm in Ethereum—as well as its hidden flaws. The course explains in detail how miners go about competing for and claiming mining rewards. As you progress, you will gain significant insights into the complex trial-and-error tasks facing miners and learn how hidden flaws in the process can then be addressed by the proof-of-stake algorithm. Learn to appreciate the functions and worth of smart contracts that eliminate the need for a trusted third party in many transactions. Finally, familiarize yourself with the important features of Solidity programing language, and begin to understand the important roles played by gas price and gas fields in any Ethereum transaction.
WHAT YOU WILL LEARN
-
describe the role of miners in picking up initiated transactions and then ordering and verifying them
outline the proof of work algorithm and the work which miners need to do to claim mining rewards
recognize the difficulty in finding the proof of work nonce and why it can only be found by trial and error
recall when a miner can claim mining rewards and how the other nodes in the Ethereum network will validate its claim
identify the flaws in the proof of work algorithm and how the proof of stake algorithm can address them -
describe the need for smart contracts to eliminate the need for a trusted third party in many transactions
list the features of the Solidity programming language
outline the concept of gas in Ethereum and the role of the gas price and gas limit fields in a transaction
recall the steps involved in the proof of work algorithm and the flaws in this technique and identify the functions of smart contracts
