The Increasing Role of A Blockchain Developer | Simpliv

Blockchain technology revolutionized the world, no less. It is now being used in various industries, such as marketing or even banking. Even though this technology is relatively new, it is already widely known, and more and more companies are searching for ways to include it into their daily workflow and hire blockchain developer.

With its tendency to simplify business processes, blockchain will surely become an important tool of corporations’ organization. Having said all that, there is no surprise that the role of the blockchain developer became one of the most demanding in the modern market.

Let’s learn more about these specialists and what value they can add to the business.

Blockchain Development: An Overview

Probably everyone has heard of blockchain by now, however, not everyone knows what kind of technology it is and what it could be used for.

First and foremost, this technology is a record-keeping system that grants access to any Internet user out there. The data put into the blockchain cannot be removed and can only be further specified in case of changes.

This technology is insanely versatile thus it is being used in various industries. Even though most people associate blockchain with cryptocurrency, it is also being widely used in banking, medicine, retail, voting systems, digital retail, etc.

Due to the increased popularity of this technology and variety of cases where it can be used, there is no wonder that the role of the blockchain engineer is getting high in demand as well.

Blockchain Developer Duties

It would be hard to keep going about blockchain software engineercareer path popularity without explaining their duties first. Previously we have mentioned that blockchain is basically a chain of informational ‘nodes’ that are connected to each other and consist of encrypted data pieces. So blockchain developer is a person who is responsible for applications’ development that are being executed on each particular node of a blockchain.

The biggest challenge of this job is to make sure that the code, written for blockchain can be used in a successful cooperation with a ‘classical’ code.

Now, if you decide to hire blockchain developer, you will need to know that currently there are two main types of them – core and software ones.

Developers of the first type are usually responsible for the architecture of the blockchain, design of its protocols, and other high-level decisions. On the contrary, Software blockchain developers are being somewhat dependent on the previous type, as they use the results of the core blockchain developers’ work to build applications that would be run on blockchain.

Blockchain Developer Skills

Regardless of the type of a blockchain developer you are looking for, there is a set of certain skills that either of them should obtain:

  • Blockchain architecture. Obviously, a good blockchain developer should know this technology from inside and out, being expert in how blockchain protocols are being built, and so on. Also, a great specialist of this field should be familiar with all professional terms.
  • Proficiency with data structure. Data structure is one of the core elements of blockchain technology and is a key to understanding its true capabilities.

  • Cryptography. Blockchain is all about security so any good developer of this field usually knows two or three such methods to ensure the safety of the data.
  • Smart contract. Smart contracts are those particular functions that allow business seamlessly incorporate the blockchain technology into their workflow. Usually it means learning a few particular programming languages such as Viper or Chaincode.
  • Web development. Blockchain development might differ from web development as we know it, however, knowing the basics is a ‘must’ for anyone who is thriving to become an expert of it, especially major aspects of front-end and back-end development.

Public Speaking Fear: Steps To Overcome It (Like A Pro) | Simpliv

If you thought your fear of cockroaches was the most prevalent fear, you are wrong! The fear of public speaking beats this phobia by a mile. Would you believe it, if told, that the fear of public speaking exceeds the fear of death among Americans?

Illogical as this fact may sound, this fact is cause for some serious reflection. When we have such a large fear right in our midst-three in four people have it by some estimates-isn’t it time to look at this issue?

My intention is to help my readers understand this phobia from a few select perspectives. I will dwell into an understanding of what this phobia is, but more importantly, I will try my best to offer solutions on how to overcome it.

Ready? Let’s get started. Even before I venture out to laying out what all I will be covering in this blog, I want to warm up your minds with a course what fits this topic like a peg to a hole. Take some time off to go through this lovely educational material. It will aid and supplement the article that is going to unfold before you over the next few paragraphs.

As promised, I will first lay out the outline for this blog. This blog’s outline is as follows:

  • Public Speaking Anxiety
  • How do I know if I have social anxiety?
  • What are the signs of speech anxiety?
  • What are your greatest fears of public speaking?
  • What causes a fear of public speaking?
  • Why are so many people afraid of public speaking?
  • How to keep your nerves calm during a speech, aka tips for helping you overcome the fear of public speaking
  • What are the best ways to overcome social phobia?
  • How to deal with sudden anxiety or a panic attack in public
  • Is the fear of public speaking bad for you? How to know if it is good or bad for you?
  • What is Cognitive Behavioral Therapy?

Public Speaking Anxiety

The first step to dealing with public speaking anxiety is obviously, to get an understanding of what it is. So, let me get started on the common understanding of public speaking anxiety. The words spell out what this malady is: the fear or anxiety of speaking in public. Here, the public need not be the person on the street or the park, but someone who has a connection with the speaker in some or another way.

Let us say lecturing is a kind of public speaking. Why this qualifies so is because the lecturer is speaking to a set audience, mostly students, on a defined topic in a defined space, which here could be the classroom. If the lecturer had a fear of lecturing to the students, then, this anxiety would be called public speaking anxiety.

So, this is a bare definition of public speaking anxiety. Further, let us get down to the etymology of the common phrase used to describe public speaking anxiety. The word for public speaking anxiety is glossophobia. This phrase is derived from the Greek words, “glossa”, which means language, and phobia, whose meaning most of are familiar with.

How do I know if I have social anxiety?

So, how do you (or I) know if we have social anxiety? Simple: if we have public speaking anxiety, we are suffering from a kind of social anxiety, because psychologists consider this so. In fact, their relationship with each other is so close that many people use these two words interchangeably, which is what I too, am doing through most of this blog. People suffering from social anxiety are prone to their own unique signs, which I will explain in the next paragraph.

However, we need to draw a distinction here. The social anxiety we are talking about is something that affects people who are otherwise normal in every other sense. When social anxiety or fear of public speaking affects people who are diagnosed with speech issues, this does not make them candidates for social anxiety or glossophobia. Their case is quite different.

What are the signs of speech anxiety?

Well, it is important to note that what we classify as signs of anxiety can happen to most people once in a way, on specific occasions, such as while meeting strangers, giving a presentation for which we could be unprepared, facing tough situations at work, etc. But what is different about people with this disorder is that they exhibit these signs in their day-to-day interactions with people. With such people, it is a mental condition that can affect their daily routines.

These are some of the telltale physical sigs and symptoms of speech anxiety or fear of public speaking, each of which is quite self-explanatory. However, I want to go a little beyond just listing these. I will set out to suggest which of the tips I have suggested in the beginning works best for each of these:

The feeling of “butterflies in the stomach”: This is a fairly common trait not only among people who are nervous about public speaking, but also among top notch performers! Can you ever believe if I told you that some of history’s greatest names suffered from stage fear, but, like great men, overcame it? This “illustrious” list includes Warren Buffett, Mahatma Gandhi, Thomas Jefferson, Abraham Lincoln, and Joel Osteen! So, relax and stay inspired.

So, take heart, because, after all, only the first few moments can be like this. It will sort of iron out with time. To overcome this, the tip I would suggest is the one on getting used to the ambience. It is just like the darkness we experience when entering a cinema, to which we get adjusted after a little time.

Sweating: The medical world says that we sweat during anxiety because the brain perceives a certain degree of anxiety and releases the stress hormones, adrenaline and cortisol, which in turn stimulate the eccrine and apocrine glands, the sweaty glands. So, the way to address this problem is simple: apply the tip on deep breathing/meditation, because this calms the mind and works wonders.

Dry mouth: This again is related to the condition where the brain, when nervous, sends out a variety of signals to show that it is going through a tense situation. Dehydration is the direct physical cause of a dry mouth, so drink lots of water. And yes, meditiation is a readily available tip to overcome dry mouth when you are going through anxiety.

Shaking: Shaking is one of the most conspicuous signs of anxiety, especially public speaking. This requires you to cultivate the right frame of mind if you want to overcome it, because like sweating, this can also settle down after a few moments.

Quickened heartbeat: Another very identifiable symptom of anxiety; quickened heartbeat is something you can overcome with deep breathing. Let me assure you, it works wonders.

Difficulty in finding one’s voice: The main reason we get a difficulty in finding our voice is that when we are nervous, we are eager to show that we are not, as a result of which we end up exacerbating just what we wanted to suppress! Nothing to worry, because I have mentioned the tip on using some body gestures in helping to soothe the nerves. Just try them out.

What are your greatest fears of public speaking? 

According to Forbes magazine, there are as many as seven greatest fears of public speaking:

Selfdoubt:

Doubting whether one can summon all the talents and confidence at the precise time of facing the audience can rattle even gifted speakers

The audience: This is another fear of public speaking, and quite rightly so. This is all the truer if the audience consists of heavyweights

Surprises: We all love surprises, but certainly not of the kind an unexpected question or intervention at a public speech!

Nervousness: This trait is pretty common amongst most people, and hence needs no elaboration

Technology:

What if the ppt fails? What if I fumble with the app that I am using for the speech? These anxieties are quite understandable fears of technology that can impede public speaking

Forgetting: How will I manage if I forget important points of my presentation or speech? This question can bug most people who are required to give a public speech

Time: How do I pack my speech and finish within the stipulated time? Am I going to cover all the points or will I miss out important ones?

7 Academic Writing Essentials: Skills You Need To Master Today! | Simpliv

Academic writing plays a crucial role in day to day life of students at various universities. As per a study, academic writing is one of the skills students find difficult to develop. Even students from native English-speaking countries struggle to maintain the standards of academic writing. These challenges arise from a poor understanding of any of these:

  • Structure of academic writing
  • Purpose and different types of academic writing
  • Plagiarism
  • Research methods

If you can relate closely to any of these above challenges, then you are not alone. One of the common questions we get to read these days on platforms such as Quora is “What is academic writing?”

Academic writing is a skill that you need to learn to convey your ideas, share your thoughts, and engage in scholarly conversation.

It is a challenging task for any writer to present a good academic paper that is clear and effective, and which can be well received by the readers.

Academic writing is different from personal writing as this mode of writing follows its own set of rules and practices. In this format, ideas are usually organized in a formal order and are supported by references from academic literature.

Making a good research work on your chosen subject holds the key while writing your academic paper. Without proper research work, it will be very difficult to put your ideas and thoughts on paper about the subject.

We present here a blog for the benefit of people who are willing to learn the ways of writing an academic paper in a proper and effective manner. In this section, we will  discuss  some key points that you need to know while learning about academic writing.
