Learn blockchain development: What are nodes and masternodes?

Posted on by Imarticus

The base of any type of development is the proper infrastructure. Blockchain development is no different! When you learn blockchain development, you will be coming across terms such as nodes and master nodes. These are some crucial components of the infrastructure of blockchain. They help with the accessibility of the data in a blockchain. What are they? What do they mean? Let’s find out!

What is a node in blockchain?

As you know, in a blockchain, data is stored in blocks. Nodes refer to the specific areas in these blocks where the data is stored. In simple terms, nodes are the building blocks of blockchain and comprise the computer systems, servers, or any devices that are used for transactions. The nodes are all interconnected to form a strong network that will be hard to manipulate. 

There are different forms of nodes such as light nodes which are the users, full nodes which means the systems used for the information transfer, and the master node that has a larger role over the others. There also are other types of nodes depending on their functions and capabilities. A blockchain developer course in India provides more insight into the various types of nodes. 

Masternodes are the components that have more authorization for the various functions among the nodes. They come with sophisticated software specifications to perform additional tasks other than the common function such as storage, validation, or broadcasting. They also act as the governing center and the law enforcement department of the blockchain. 

To become a blockchain developer one must master the knowledge about nodes and master nodes. Even then, operating master nodes is not easy as it requires paid permission to gain access to it. 

How to become a blockchain developer?

Now, you might have got a glimpse of what constitutes a blockchain. So to become a master developer, the primary requirement is to learn blockchain development with the help of a top course. 

The SCBI course here at Imarticus will be a great start. This is a 9-month course offered in collaboration with IIT Guwahati. This Certification in Software Engineering for Cloud, Blockchain & IoT course provides in-depth knowledge in all three areas. The course is suitable for anyone starting from scratch as well as for those having some experience in this field. But obviously, it will be easier for those with some experience. 

What more is there with blockchain development?

Understanding nodes and master nodes are just entry points for blockchain development. They are just some significant parts of the blockchain system but there is a lot more to learn for developing a system. 

The road ahead reveals some programming languages, concepts of mining, hashing, etc. A quality course will also give you the opportunity to learn from the experts in this industry and a chance to be mentored by them. 

Having hands-on experience with a project to finish off the course will prepare you well for the job description and the challenges associated. It will also enable you to come up with an innovative way for the models and their implementation. 

Types of blockchain developers

There are two types of blockchain developers- Blockchain software developers and Core blockchain developers. The former create applications based on the protocols and provided architecture. The latter type of developers is the ones who create a blockchain architecture from scratch. 

The SCBI course helps the former type of developers to create application-based blockchains. It also covers the data science areas such as programming languages, AI, ML, etc. 

2022- The Wake-Up Call for Strong Logistics Management?

Posted on by Imarticus

The global pandemic was a downward spiral for several industries but the logistics industry handled it as a wake-up call. Even though there are several areas where they incurred loss, the overall outcome of the pandemic proved to be positive for it. Increased use of AI-driven technologies has helped this industry map a new strategy for the upcoming years. 

The last two years have been a learning curve for the logistics industry so, in the year 2022, the industry needs to strategize its moves for the upcoming years. With the help of the latest technologies, those who have completed a Logistics and supply chain management course could extend their services to change the overall face of this industry. 

Future of logistics industry in 2022

The COVID-19 pandemic forced the supply chain system to shift from the low-cost management system to an agile framework of data-driven technologies. A major percentage of companies in this industry have already invested in such technologies. It helped the management to make decisions based on the data. The future of this industry will be seen in some key areas. The future trends in these areas are mentioned here. 

  • Better visibility

One of the strong positive outcomes of the pandemic is higher visibility of the supply chain system. The real-time tracking of the consignments and instant feedback from the customers etc will enable the companies to have a re-evaluation of themselves. They can use the data to make appropriate decisions and make their service more impactful. 

  • Optimized network

A logistics company may be provisioning shipments internationally, nationally, and in local areas. They must have a quality optimized network to have customized changes according to the region and the behavior of the customers. 

  • Changing customer expectations

When the supply chain system has improved its functioning the expectations of the customers have also increased many folds. They expect lower costs with faster shipping and a simplified return policy. They are even ready to pay for the same-day delivery so the companies must comply with such demands and make the necessary changes. 

  • Better risk mitigation

Utilizing centralized data to come up with reliable forecasting plays a huge role in preventing losses. The major steps that can prevent loss or risk are automation and optimization of the various processes. It helps minimize the possible errors. This is one of the strong points that you can learn from a supply chain management online course. 

  • Stronger relationship management

A resilient industry requires stronger relationships between the various departments and the personnel involved. A larger company may find it difficult to comply with this but they can share the data among all the departments and bring them all to the same page. This will eliminate the issue of lack of visibility in the lower levels of the chain. 

Conclusion

The best approach for logistics companies is to hire professionals who are trained to achieve these goals. They can understand the changes much better and can also come up with successful strategies that have a positive impact and reduce risks. 

One of the best and most popular choices for the aspirants is to choose the Certification in Supply Chain Management and Analytics course from Imarticus. The course is in collaboration with IIT Roorkee. 

This course will be ideal to prepare you for the job description of a Supply Planning Analyst, Supply And Operations Planner, or Logistics Manager with the right knowledge in the key operational areas. Upskilling with the latest technologies and methods will be essential to understand future trends so that you can make appropriate decisions. 

An introduction to Cybersecurity certification and capture the flags contest

Posted on by Imarticus

The Cybersecurity course we offer at Imarticus delves into the vast topic of cybersecurity, focusing on the significance of data confidentiality, cybersecurity, best practices for using social media and the internet securely, and prospective job prospects in this rapidly increasing industry. It discusses how to secure your privacy and personal data online and on social media, as well as why cybersecurity knowledge and awareness are becoming increasingly important in IT careers.

We are all increasingly exposed to cyber-attacks in today’s linked society. The cyber security certifications online are for you whether you’re drawn to the relatively new field of cybersecurity professions or just want to safeguard yourself online and on social media.

It delves into cyber trends, risks, and the broader issue of cybersecurity in a way that is personally relevant to you. You will, for example, learn how to safeguard your privacy online and about the issues that corporations, governments, and educational institutions face.

Cybersecurity: Necessity and Opportunity for Every Profession.

From a hazy rumor to an ethereal reality, the phrase has come a long way.

Functioning in an ever-changing, fast-paced, and frequently hostile environment is becoming increasingly challenging for security employees with minimal IT or administrative abilities. As the globe becomes increasingly networked and globalized, the lines between security and technology departments are dissolving and merging.

Every social, commercial, and governmental layer is affected by cybersecurity. To interfere with the US election, a country can manipulate public opinion. Terrorists may attempt to hack into a nuclear power plant’s network. For ransom, a criminal network might take over a company’s database. Hacking into ATMs in Taiwan resulted in the theft of more than $200,000 in one night. Hackers gained access to the computers of prominent stock market investors, allowing them to purchase shares in milliseconds.

To pass on secret information, a manager may be blackmailed for virtual sex (“Sextortion”). With a single mouse click, an employee may download a virus and shut down the firm for a day, resulting in millions of dollars in damages. This is only the tip of the iceberg when it comes to the possibilities. We must prepare for what is still to come, which we cannot conceive. It is necessary to plan ahead.

Surveillance cameras, physical barriers and high walls, and ongoing training are all part of today’s security systems, yet everything is placed in danger every time someone walks past the security arch with a smartphone and a flash drive, and no one seems to notice.

CTF

Today’s security measures include high walls and physical barriers, surveillance cameras, and continual training, yet everything is put in jeopardy whenever someone passes past the security arch with a flash drive and a smartphone, and no one appears to notice.

To summarize, each CTF’s goal is to complete a sequence of tasks that progressively become more difficult as the number of points indicated in each job increases. These tournaments normally last 2-3 days, after which writeups for each suggested challenge are released willingly, allowing other players to learn about their strategies. If a challenge is not completed by a particular number of teams, the CTF organizers will generally provide some tips to make obtaining the flag, also known as a key, simpler.

CTFs can be classified into the following groups:

  • Miscellaneous [Misc]: Random challenges that can belong to different unspecified categories.
  • Trivia: Different questions related to computer security.
  • Recognition [Recon]: Searching for the flag in different sites on the Internet. Clues, such as a person’s name, are given to solve it.
  • Web: Discovery of vulnerabilities in a web application.
  • Programming [PPC]: Also known as PPC (Professional Programming & Coding), challenges that require developing a program or script that performs a certain task.
  • Reverse engineering [Reversing]: Inferring in the operation of the software. Most commonly, Windows and Linux binaries.
  • Pwning: Discovery of vulnerabilities in a server.
  • Steganography [Stego]: Images, sounds, or videos that hide information inside.
  • Cryptography [Crypto]: Texts encrypted using a specific cryptosystem.
  • Forensics: Most common; memory images, hard disk images or network captures, which store different types of information.
