We’ve covered what Proof of Work and Proof of Stake is, but what is PaaS?

In this article, we’re making this rather complicated-sounding term easy to understand as we explore where it came from, what it means, and why it’s likely to keep popping up in the crypto realm. 

What Is PaaS?

PaaS stands for Platform as a Service and refers to a cloud delivery service that uses third-party cloud service providers. “As a service” indicates that the cloud computing service is provided by a third party, rather than the user having to manage their own hardware and software.

PaaS providers offer a range of services, including operating systems, databases, middleware, and other software development tools. PaaS offerings can be used for both cloud-native and hybrid cloud applications.

PaaS solutions are popular among software developers and businesses looking to migrate their applications to the cloud. They provide an application development platform that can be used to build and deploy applications quickly and easily, without the need for specialized hardware or software.

Some of the key benefits of PaaS include reduced costs, faster deployment, and greater flexibility and scalability. PaaS providers offer a range of services, including operating systems, databases, middleware, and other software development tools. This allows users to develop, run, and manage applications without having to worry about the underlying infrastructure.

The History of PaaS

PaaS first appeared in 2005 as Zimki under the company Fontago. Zimki allowed users to build and deploy web services and applications through its code execution platform.

Billing was determined based on the number of JavaScript operations, the amount of web traffic and the total storage used, providing users with a much clearer cost structure than on other platforms. The platform was eventually shut down in 2008 by its parent company.

That same year the Google App Engine was launched allowing users to create web services and applications using languages like Go, PHP, Node.js, Java and Python.

Today, Google remains the biggest PaaS vendor in the world. 

How Does PaaS Work?

Instead of replacing its overall IT infrastructure and running these services in-house, PaaS streamlines access to its key services. This helps to reduce time in deployment as well as minimize startup costs. 

PaaS allows users to tap into resources and functions like capacity on demand, data storage, text editing, vision management and testing services despite being in geographically different locations. All while using a pay-per-use model. 

PaaS Offers Development Tools

PaaS, or Platform as a Service, is a cloud-based platform that provides users with access to the tools and resources needed to develop and run applications. Instead of replacing its overall IT infrastructure and running these services in-house, PaaS streamlines access to its key services, allowing users to easily tap into resources and functions like capacity on demand, data storage, text editing, vision management, and testing services. This pay-per-use model enables users to access the tools and resources they need without incurring the high costs of building and maintaining their own infrastructure.

PaaS technology offers a range of benefits for both developers and businesses, including the ability to easily integrate databases, manage infrastructure, and access data centers. This can provide a range of advantages, such as improved performance, enhanced security, and increased scalability.

PaaS technology providers also offer a range of services and support to their customers, including integration platforms and infrastructure management services. This can help businesses to quickly and easily integrate their applications with other systems and platforms, allowing them to take advantage of the benefits of PaaS without having to worry about the underlying infrastructure.

PaaS vs IaaS vs SaaS

PaaS, IaaS, and SaaS are all different models of cloud computing. PaaS, or Platform as a Service, provides access to the tools and resources needed to develop and run applications, while IaaS, or Infrastructure as a Service, offers access to the underlying infrastructure, including storage, networking, and computing power. SaaS, or Software as a Service, provides access to software applications over the internet.

These models differ in terms of what areas are handled on-site and which are handled by a third-party provider. For example, with PaaS, the infrastructure and operating system are managed by the provider, while the customer focuses on developing and deploying their own applications. With IaaS, the provider manages the infrastructure, while the customer is responsible for the operating system and applications. With SaaS, the provider manages everything, including the infrastructure, operating system, and applications.

Examples of companies that offer PaaS services include Amazon Web Services and the IBM Cloud, while IaaS providers include AWS, Microsoft Azure, and Google Cloud. Dropbox, Salesforce, and Google Apps are examples of SaaS providers.

These models offer advantages to businesses and developers looking to enter the cloud computing space. For example, PaaS offers the ability to focus on app development without worrying about the underlying infrastructure, while IaaS and SaaS provide access to cloud resources and the ability to quickly deploy and scale applications. These models can also be used to build communications platforms and other mobile applications, providing access to the necessary infrastructure and resources.

PaaS Provider In Blockchain

The use of PaaS technology, or Platform as a Service, within the blockchain industry is becoming increasingly popular. While blockchain platforms themselves are not typically structured in a PaaS way, the concept of BPaaS, or Blockchain Platform as a Service, offers businesses and enterprises the opportunity to focus on the development of software and other services for customers.

BPaaS provides numerous advantages for companies looking to enter the blockchain space. It allows businesses to leverage the power of cloud-based infrastructure and resources to develop and deploy applications without the need to manage their own hardware and software.

PaaS providers like Amazon Managed Blockchain and the IBM Blockchain Platform are leading the way in offering BPaaS solutions to businesses. These platforms offer a range of tools and resources for application development, including integrated development environments (IDEs), code libraries, and APIs. This allows developers to focus on building and deploying their own blockchain-based applications without worrying about the underlying infrastructure.

Overall, the use of PaaS in the blockchain industry offers numerous benefits, including reduced production costs, streamlined deployment, and the ability to easily integrate specific AI capabilities into applications. This makes it an attractive option for businesses looking to enter the blockchain space.

The stock market is a collective term for stock exchanges around the world. On these exchanges buyers and sellers can trade shares in publicly traded companies, known as stock. Similar to an auction, buyers can name the highest price they're willing to pay, known as the "bid", and sellers can name the lowest price they're willing to accept, known as the "ask". The trade will typically execute somewhere between these two figures.

The stock market exists across the world with stock exchanges situated in New York and Hong Kong, connecting traders through a mutual set of guidelines. Learn more about the role of stockbrokers, portfolio managers, and investors as we take a deep dive into the entire stock market.

What is the stock market?

The stock market can also be referred to as the equities market or share market. As mentioned above, the stock market encompases buyers and sellers of stocks of publically traded companies. Similar to a farmer's market, the stock market forms a base where buyers and sellers can exchange things. Unlike farmer's markets, however, stock markets are heavily regulated and more complex, with prices known to change quickly.

The primary functions that the stock market serves

• The buying of stocks: Both retail investors and institutional investors can purchase shares of companies.
• The selling of stocks: every trade needs a buyer and seller.
• The issuance of stocks: A company raising money may do so by selling a portion of ownership via an initial public offering (IPO). If the company is already public, it can raise money through a secondary public offering. After the individual stocks are issued in either case, it can be bought by or sold to members of the general public.
  Trades are typically placed by stockbrokers on behalf of individual investors or portfolio managers.

The primary market is when companies list their shares, while the secondary market is where investors trade these stocks. The secondary market is essentially the stock exchange where stock trading takes place.

It's not just stocks that can be bought and sold on the stock market. Other types of securities, such as exchange-traded funds (ETFs) or REITs, are also traded on the stock market (with some discrepancies in how they're priced and traded).

Around the world, there are 60 major stock exchanges, each varying in size and trading volume. In the United States, for instance, there are 13 different exchanges that make up the stock market, the most popular ones being the New York Stock Exchange and Nasdaq.

How does the stock market work?

The primary function of the stock market is to bring together buyers and sellers so they can trade stocks and other financial instruments. The price is set much like an auction would be.

Bid price

• Buyers determine the bid price. Stockbrokers can bid on the price they're willing to buy a stock for, and the highest price becomes known as the "Best Bid."

Ask price

• Sellers determine the ask price. When an owner of the stock or their stockbroker wants to sell, they place what's called an ask, which is the price that they would like to sell a stock for. The lowest prices become known as the "Best Ask."

The negotiation between the Best Bid and Best Ask is called the “Spread.” The two sides agree to meet somewhere in the middle, and the person who executes the trade gets paid by taking the difference.

As you follow a stock, you’ll notice the share price moves. The stock's price is always changing depending on how many people are buying or selling it and the number of trades that it goes through. As economic, political, and news stories specific to a company affect the movement of markets in general, that company's stock prices can change too as a result. This is known as stock market volatility.

Is trading on stock exchanges risky?

As with any investment pursuit, trading the stock market for both short-term and long-term periods carries a level of risk. Being prepared by knowing that stocks can increase or decrease dramatically at a moment's notice will allow you to prepare for such events in your trading strategy.

In some cases, stock prices can decrease to zero, losing all their value and resulting in a total loss of capital for the investor. While this is an extreme case, making the necessary precautions in one's trading strategy will go a long way.

Is the stock market and stock exchange regulated?

Yes, as the stock market handles trillions of dollars, government organizations around the world have been called in to regulate these markets. In the U.S. for example the SEC (US Securities and Exchange Commission) has been granted the authority by Congress to regulate the stock market because they handle such a large amount of money. Other countries have similar organizations that regulate and enforce different laws.

Regulators are responsible for:

• Safeguarding the investments of the general public
• Promoting a sense of equality and fairness
• Keeping markets running smoothly

Who are the main players in the stock market?

Below are the main players contributing to how the stock market works:

• Retail investors
  Buy or sell individual stocks through a brokerage account. When you place an order, it’s sent to exchanges where the trades are executed.
• Stockbrokers
  “Registered representatives” who have completed professional training and passed a licensing exam and are allowed to buy and sell securities on behalf of investors. Stockbrokers work for brokerages, which can either make their money through markups/markdowns or commissions on trades (known as principals or agents respectively). Fees are often charged by the brokerage to customers that use them to place orders and execute stock trades.
• Portfolio managers
  Portfolio managers are stockbrokers on a grander scale as they buy and sell stocks through large orders as they manage larger stock portfolios. These might include mutual funds, retirement funds, and pension funds, which contain a bundle of securities (stocks, bonds, etc) that are handled by the portfolio manager.
• Investment bankers
  Help companies list their shares publicly on exchanges.

Who makes up the stock market ecosystem?

To better understand how the stock market works you will need to understand the varying components that make up the primary market. Investors buying and selling stock make up the biggest component of the stock market, however, there are plenty of middlemen acting between those buyers and sellers earning money by providing services to them. Below are some examples:

• The stock exchanges charge a small transaction fee and listing fee to the companies that offer their shares on the exchange.
• Agents are the middlemen connecting the buyers with sellers. For connecting each side of the transaction they take a commission.
• Principals are broker-dealer firms that manage a portfolio of shares they're willing to sell. Broker-dealers usually earn a profit by adding a markup to stocks they sell and charge investors less than the full value when buying stock. For example, have you ever noticed how much more car dealerships will sell cars for versus what they offered to pay you for your old one? Brokerages do something similar with stocks.
• Retail investors are people who invest for themselves, and not as part of their job, are retail investors. These individuals manage their own stocks (or other assets) through personal accounts with brokerages.
• Custodians. Brokerage firms use custodians to physically hold stocks, which is seen as less of a risk in terms of loss, theft, or damage. For doing so they charge a fee.

What is the history of the stock market?

The original concept of the stock market is the opportunity for a company to divide its ownership, known as equity, and sell it to investors. This practice dates back hundreds of years to the 1600s where European explorers would raise money for their ventures by selling shares in the company.

Investors would then get a cut of the explorer's missions, whether it be bringing back foreign spices or animal hides. The Dutch East India Company was a pioneer in this movement, selling shares in exchange for future profits on Amsterdam's stock exchange.

A century later and the first modern stock exchange was launched in London. Due to a high amount of fraud and minimal information on the company available to the public, the London Stock Exchange was created in 1773 which provided a consistent and fair platform on which to trade stocks.

Across the pond in 1790 the first stock exchange was formed in Philidelphia, followed shortly after by the New York Stock Exchange. Fast forward to modern days and the NYSE now provides both digital trading and a physical trading floor on Wall Street, the latter of which is a National Historic Landmark.

Nasdaq (National Association of Securities Dealers Automated Quotations) launched in 1971 as the world's first electronic market. The electronic stock exchange is a popular option for tech companies looking to list their shares and a crosstown rival to the NYSE. From a trading perspective, where the shares are listed makes little to no difference to the investor.

In conclusion: what is the stock market?

The stock market is a collective term for stock exchanges around the world that facilitate the trade of stocks and other financial instruments.

Used across all markets, the spread is the difference between the buy (offer) and sell (bid) prices of an asset. Spreads provide an additional opportunity to traders to make money through buying and selling assets.

The spread of an asset will depend on the current demand or an asset and the market’s volatility and is presented in either a percentage or value form. Assets with markets displaying higher levels of demand will typically have smaller spreads and usually higher price points. 

As an example, when you look at an order book for Bitcoin you will usually see prices reflected in green and red reflecting the offer prices and bid prices. The spread will then be indicated above the most recent trades. As another example, consider foreign exchange counters where the buy and sell prices are different, this difference is known as the spread. Market makers use spreads to generate money from transactions completed at market prices.

Let's put this in context: George buys 100 shares for a £2 ask price in “ABC” a publicly listed company. George pays £200 in return for 100 shares. If he decides to sell the shares back at the same price he bought them for, he would sell the 100 shares for the bid price at £1.95 and would receive £1.95 each instead of £2. This would mean he gets a return of £195 and loses £5, which would be paid to the market maker.

Risk in trading is the chance that something might negatively impact an investment. Before engaging in any trading activities it is important to evaluate your appetite for risk, determining whether you are able to handle more risk or are more risk averse. 

Measuring risk will be dependent on the type of asset you are investing in, the amount of capital you have to use, and the time frames in which you expect to see results. Different assets and trading strategies hold different amounts of risk. 

For example, investing in an index fund is considered a low-risk investment and is better advised to investors looking to make a slow and steady return over a longer period of time. Index funds aggregate the performance of the 100 companies listed on a particular stock exchange and pay back dividends accordingly. Because they are large companies the growth is often more likely to be smaller yet consistent. 

With a little more appetite for risk, in the crypto markets, the same could be said about choosing to invest in an emerging altcoin versus established cryptocurrencies like Bitcoin or Ethereum. An emerging asset would encompass a higher risk higher reward ratio, however, no returns are guaranteed. 

You can speak to a financial advisor to get a sense of your risk appetite.

Risk management involves identifying and analysing the risks involved, and then choosing whether to accept this risk or make changes to avoid the risk. This process is one we carry out daily, from crossing the street to engaging with a stranger, however, in this realm we’re looking at it from a finance/investment point of view. 

If you have a fund manager or financial adviser, they will generally be responsible for calculating and communicating the risks associated with any type of investment. This will cover the potential returns as well as the potential risks to your capital. 

For example, investing in an emerging asset will hold a lot more risk than buying the stocks of a well-established institution. It’s worth noting that high risk doesn’t necessarily equate to a negative, typically assets with higher levels of risk bring about higher levels of return (high risk, high reward).

Each person’s level of risk will vary from one to another and should be decided prior to making any investments. Once this is established, your investment portfolio will work within those realms so as to manage that level of risk.

We have all heard older generations complain about the price of products "nowadays", talking about how $1 used to buy them a movie ticket and popcorn, compared to the average cost of $10 for just a ticket today. They aren't complaining about nothing, this is a very real issue the world is currently facing and it's known as inflation.

Although, with the way the economy has been going lately, hyperinflation may feel like a more fitting term. In basic terms, hyperinflation is referring to a very high and accelerating inflation rate. Let's cover what inflation is, and how this differs from hyperinflation.

What is inflation?

Inflation refers to a decrease in purchasing power related to a specific currency. This means a progressive increase in the price of goods and services results in a certain amount of money being able to buy less over time.

As already stated above, what $1 used to buy back in the day is merely a fraction of what the product or service now costs. Usually, inflation occurs at a gradual rate, however, there have been instances where inflation rates have accelerated at much faster speeds. This rapid acceleration rate leads to the value of a country's currency being diminished at an alarming rate. This is then referred to as hyperinflation.

Hyperinflation is measured when the inflation rate increases by 50% or more in one month.

What causes hyperinflation?

You may be wondering how hyperinflation occurs, and that's a great question. From an economic standpoint, there are two main causes, although external factors can also come into play. External factors might include war, natural disasters, a pandemic, and more, however, here we will be covering the two main causes.

Number one is an increased money supply. Most think that an excess supply of money sounds great, but it can have colossal impacts on a currency if not backed by economic growth. Countries usually grow through trading, businesses, and bringing money into the country from outside the borders.

This issue comes into play when countries print money at an accelerated rate, increasing government debt with central banks which they then have to pay back with interest. This additional interest and debt gets placed on citizens, who are then expected to pay more tax and pay more for products. 

The second is demand-pull inflation. This can also be described as supply vs demand. While some small businesses see this as a benefit, being able to increase prices due to their unique products, the same can not be said for common household items. This inflation occurs when the demand for products goes up, especially as capitalism rises, yet the production of said products can not contend. 

This creates a gap within the supply, making it hard for businesses and economies to make money unless they raise their prices. So again, we see product prices rising thus reducing the purchasing power of a currency. 

The effects of hyperinflation 

One of the most common effects of hyperinflation is the devaluation of currencies, moving those who hold them to switch to more valuable assets. Whether it is investing in the stock market or another currency, this takes additional money out of the currencies' economy and proceeds to make hyperinflation worse. Luckily those who have invested in other means of value are not as affected by this additional pressure.

Previously, inflation in Zimbabwe reached such dire levels that the country ultimately wrote off its national currency and switched over to the US dollar. At one point, their currency was so hyperinflated that their $100 trillion Zimbabwe dollar banknote could only buy a few loaves of bread. This impact affected banks, foreign trading, and basic government services, creating another ripple effect leading to further inflation. It's a problem that continues to occur, ravaging countries and livelihoods around the world.

Hyperinflation and monetary policies

Central banks play a vital role in preventing hyperinflation through the implementation of monetary policies.. As they control the money supply, regulate interest rates, and oversee the stability of the currency, central banks are responsible for maintaining a balance between growth and inflation. Done so by carefully monitoring economic indicators to manage and prevent potential risks of excessive growth and inflation.

In order to keep hyperinflation at bay, governments need to practise responsible fiscal policies, avoiding excessive borrowing and uncontrolled spending. Maintaining a stable exchange rate and encouraging foreign investments can also strengthen economic stability.

How to combat hyperinflation

In an attempt to curb the devastating effects of hyperinflation, below are four measures that governments and central banks could implement.

Tightening money supply

An obvious one, central banks can reduce hyperinflation risks by curbing the rapid increase in the money supply. This involves limiting the printing of new money and implementing stringent monetary policies.

Interest rate adjustments

By raising interest rates, central banks can discourage excessive borrowing and spending, which acts as a means of stabilising the currency's value and mitigating hyperinflationary pressures.

Currency controls

Implementing currency controls can be a smart move to stop money from leaving the country and prevent risky speculation, all while keeping the currency strong during uncertain economic times.

Currency reforms

In extreme cases, currency reforms, such as introducing a new, more stable currency or adopting a foreign currency as legal tender, can be considered to tackle hyperinflation and restore economic confidence, as was the case with Zimbabwe mentioned above.

Examples of hyperinflation in history

These instances from the past where hyperinflation wreaked havoc serve as a clear indication of the devastating economic impact it can have on countries.

Germany (Weimar Republic):

During the early 1920s, Germany experienced one of the most infamous hyperinflation episodes. Printing money to cover war reparations led to the German Mark's catastrophic devaluation, resulting in absurd price increases and widespread economic collapse.

Zimbabwe:

Mentioned above, in the late 2000s, Zimbabwe endured a severe hyperinflationary crisis, reaching unimaginable levels. Rampant money printing and political instability eroded the Zimbabwean dollar's value, rendering it practically worthless and forcing the country to abandon its currency.

Venezuela:

Starting in the 2010s, Venezuela suffered a hyperinflationary spiral driven by a combination of political mismanagement, plummeting oil prices, and economic turmoil. This ongoing crisis has caused immense hardships for the Venezuelan population.

Yugoslavia:

In the 1990s, Yugoslavia grappled with hyperinflation as a result of political fragmentation and war. Spiralling prices led to the eventual replacement of the Yugoslav dinar with new currencies in several successor states.

Hungary:

Post-World War II, Hungary faced hyperinflation of unprecedented proportions. Skyrocketing prices and economic instability plagued the country until it eventually switched to a new currency.

These history lessons serve as cautionary tales, showing us just how terrible hyperinflation can be and why it's crucial to have solid monetary policies in place to protect against these economic disasters.

In conclusion

Hyperinflation, rapidly increasing inflation rates, is a serious economic problem with disastrous effects, as seen in historical examples like Germany, Zimbabwe, Venezuela, Yugoslavia, and Hungary. While central banks play a crucial role in preventing hyperinflation through monetary policies, governments must too play their part and practice responsible fiscal policies.

While inflation rates might feel dire, hyperinflation is highly unlikely to ever take effect in the United Kingdom as The Bank of England and government have many tools at their disposal to identify and prevent the onset.
