Blockchain And Internal Audit
|Blockchain Basics & Cryptography, Gary Gensler, Massachusetts Institute of Technology, 0:30|
The need for internal audit to provide effective oversight of organizational efficiency will require a change in the way that information is accessed in new formats. Blockchain adoption requires a framework to identify the risk of exposure associated with transactions using blockchain. The Institute of Internal Auditors has identified the need for internal auditors to address this transformational technology. New methods are required to develop audit plans that identify threats and risks. The Internal Audit Foundation study, Blockchain and Internal Audit, assesses these factors. The American Institute of Certified Public Accountants has outlined new roles for auditors as a result of blockchain.
What Is Cryptocurrency
A cryptocurrency is one medium of exchange like traditional currencies such as USD, but it is designed to exchange the digital information through a process made possible by certain principles of cryptography. A cryptocurrency is a digital currency and is classified as a subset of alternative currencies and virtual currencies.
Cryptocurrency is a bearer instrument based on digital cryptography. In this kind of cryptocurrency, the holder has of the currency has ownership. No other record kept as to the identity of the owner. In the year 1998, Wei Dai published B-Money, an anonymous, distributed electronica cash system.

What is it about? And how can you learn more about Blockchain yourself?
What is “Blockchain”?
The Blockchain technology is mainly known because the digital currency “Bitcoin” is based on it.
But what exactly does Blockchain mean?
- Blockchain technology allows for a . That may not sound exciting, but it enables some interesting applications.
- As a key application, a central authority can be replaced by a decentralized Blockchain system. The Blockchain system has the same level of reliability and lower costs.
- Instead of a bank controlling monetary transactions, for example, the no longer needs a higher authority and nevertheless works tamper-proof.
- Other possible applications include real estate land registers and other central registers for assets or documents.
While the cryptocurrency Bitcoin has already gained widespread recognition, most other Blockchain use cases are still at the very beginning of their realization.
Reason enough to learn more about this exciting new technology!

Types Of Blockchain Architecture
Now that we have understood the core components of any blockchain network, we should also learn about the different types of blockchain architecture.
Public Blockchain Architecture
In a public blockchain architecture, anyone can participate in the network. The transactions public info is available to everyone. However, this doesnt mean that the private data of a transaction are available anymore. Examples of public blockchain architecture include bitcoin, Litecoin, and Ethereum.
Private Blockchain Architecture
When it comes to private blockchain architecture, not anyone can access the blockchain. The administrator or the ruling set of nodes determines who can join the network.
Want to understand the differences between public and private blockchain? Heres a guide to the public vs private blockchain that you can check out.
Federated/Consortium Blockchain Architecture
The last type of blockchain architecture is the federated/consortium blockchain architecture. It combines the best features of both public and private blockchain. It is also heavily controlled and is best suited for enterprise blockchains.
To see the difference, lets go through the chart below.

Blockchain Crypto And Bitcoin Whats The Difference
The 3 notions of blockchain, cryptocurrency and Bitcoin are closely related. Indeed, the pseudonymous Bitcoin creator Satoshi Nakamoto actually created Bitcoin, the first successful cryptocurrency ever, and blockchain, i.e. the technology that supports it. However, while commonly mistaken for being the same, they are completely different topics that you must clearly understand and differentiate.
Lets use a simple analogy. Websites are a well-known Internet application to share peer-to-peer information. Search engines are among the most common ways to use websites by facilitating access to them. Google is one of the most famous and used search engines. To some extent, blockchain, cryptocurrency and Bitcoin share a similar relationship: blockchain is a groundbreaking technology to stock and share peer-to-peer value and information online.
Once This Is Launched Do You Have Plans To Extend It
We dont have specific plans at the moment, but we do have ideas for other things that could be taught. Cryptography for blockchain professionals might be interesting, or going deeper into a particular technology or programming language, or developing products with a particular framework. Im really looking forward to getting feedback from the people that take this course on what other kinds of things are they interested in, especially after they have finished and have a better understanding of whats out there. What are the things you wish we would have dived deeper into, or what other courses would you like to see?

What Is A Block
A Blockchain is a chain of blocks which contain information. The data which is stored inside a block depends on the type of blockchain.
For Example, A Bitcoin Block contains information about the Sender, Receiver, number of bitcoins to be transferred.
The first block in the chain is called the Genesis block. Each new block in the chain is linked to the previous block.

Hello, all hope you all are having a great time and are working towards your goals for this year. I have been sharing a lot of courses and tutorials recently about what to learn this year, starting from tools and frameworks to libraries and programming languages, but one of the most important technologies you can learn this year is blockchain development.
It’s one of most talked about technologies at the moment and is considered to be the Next Big Thing after the invention of the Internet, as blockchain technology can provide a way to attain digital trust on via the Internet.
Though I must say that the rally of cryptocurrencies has a huge role to play in the widespread adoption of blockchain. For example, I’ve known about Bitcoin for a long time but never invested in it, and the same goes for blockchain.
Even though I knew about it, I never thought to learn blockchain development or write tutorials about it. That is until I realized that it might worth my time to learn more about blockchain.
There is such a great emphasis on blockchain development as finance, real estate, healthcare, and other sectors are very keen to adopt them.
Venture capitalists are currently diverting a lot of investments into funding blockchain-based companies, which means there could not be a better time to learn about blockchain then this year, and there is no better way to start than with free online courses.
Become A Blockchain Developer Milestone #: Get Educated On Smart Contracts
How do you define a smart contract?
According to Wikipedia, a smart contract is a computer protocol intended to facilitate, verify, or enforce the negotiation or performance of a contract. While it was first proposed by American cryptographer Nick Szabo in 1996, Ethereum is often credited with popularizing the concept and making it mainstream.
You can learn more about smart contracts in our in-depth guide here.
So, what are the desirable properties that we want in our smart contract?
Anything that runs on a blockchain needs to be immutable and must have the ability to run through multiple nodes without compromising its integrity. As a result of which, smart contract functionality needs to be three things:
Feature #1: Deterministic
A program is deterministic if it gives the same output to a given input every single time. Eg. If 3+1 = 4 then 3+1 will ALWAYS be 4 . So when a program gives the same output to the same set of inputs in different computers, the program is called deterministic.
There are various moments when a program can act in an un-deterministic manner:
Feature #2: Terminable
In mathematical logic, we have an error called halting problem. Basically, it states that there is an inability to know whether or not a given program can execute its function in a time limit. In 1936, Alan Turing deduced, using Cantors Diagonal Problem, that there is no way to know whether a given program can finish in a time limit or not.
Feature #3: Isolated

Become A Blockchain Developer Milestone #: Learn The Process
It is pretty surprising to see how many budding developers have not had any real-world first-hand experience with cryptocurrency at all. How can you possibly innovate and improve upon a platform when you have not used it even once?
It is strongly recommended that you start getting acquainted with the system today.
Go to Coinbase or any other exchange that you are comfortable with or is accessible in your country and buy some coins. You dont need to create an extensive portfolio straightaway, just buy a few coins and see how the whole process works.
It is extremely straightforward. Since you are not going to be buying a lot of coins then simply use a basic online wallet.
These wallets are the easiest to use among all. The creation is super simple because its basically creating your own account on any of the exchange services. Furthermore, you can access this wallet from any server or any device in the world as long as it is connected to the net. Having said that, there is one big problem when it comes to online wallets. Your private key is going to be saved on another server. This is basically like serving up your key to hackers on a silver platter. Do NOT use online wallets to store huge amounts of your money. Store the bare minimum that you need for exchange purposes.
We are bringing this section to a close here, the tough part starts from the next milestone.
Your action steps are here:
- Learn how the exchanges work.
- Get acquainted with wallets.
