What Are Public, Private, and Consortium Blockchains

When people hear the word “blockchain,” people usually think of Bitcoin. Bitcoin is known as a public blockchain, which is the most common type of blockchain. However, many people are not aware that other blockchains exist in addition to public blockchains. The list includes private and consortium blockchains. So, what is the difference between public, private, and consortium?

Public Blockchain

A public blockchain is the most popular type of blockchain. Bitcoin, Litecoin, and Ethereum are public blockchains. The common denominator in a public blockchain is the fact that all transactions can be sent and received by anyone in the world.

All nodes within a public blockchain are given the same transmission power. Additionally, each node has the authority to audit transactions. Therefore, all nodes in a public blockchain are decentralized and fully distributed.

Most people in the crypto community would agree that decentralization is a major benefit offered by public blockchains. Another added benefit is the high level of security. Due to the fact that all transactions can be checked by anyone, fraudulent activity is much easier to detect.

Private Blockchain

A private blockchain is the exact opposite of a public blockchain. A single authority or organization has control over the network. Users must obtain permission from the organization to gain access.

Private blockchains are most useful to businesses that need to maintain privacy and security. For example, two companies that are collaborating on a top-secret project would benefit from a private blockchain.

A private blockchain is completely centralized because public access is not ordinarily permitted. But private blockchains have similarities with decentralized public blockchains.

The network is based on a peer-to-peer format, where each user maintains a complete copy of the ledger. Additionally, the ledger is immutable, which means it can’t be changed or altered. Also, the private blockchain requires consensus approval for any additions to the network.

Consortium Blockchain

A consortium blockchain is a mixture of public and private blockchains. In a consortium blockchain, only a select few nodes of the network reserve the right to authorize transactions. The remaining nodes within the network are assigned the tasks of creating new transactions, reviewing transactions, and examining blockchain history.

The division of power within the consortium is dependent on the network. Each consortium can be different from other consortiums in terms of the consensus process. The remaining features of a consortium blockchain are generally a mixture of public and private blockchains.

Brief Summary of Public, Private, and Consortium Blockchains

  • A public blockchain is the most common blockchain.
  • Bitcoin blockchain is an example of a public blockchain.
  • All nodes in a public blockchain are decentralized and fully distributed.
  • The major benefit of a public blockchain is decentralization.
  • A private blockchain is the opposite of a public blockchain.
  • Permission is required prior to gaining access to a private blockchain.
  • Public and private blockchains have many similar mechanisms.
  • A consortium blockchain is a mixture of public and private blockchains.
  • Only a select few nodes of the network reserve the right to authorize transactions on a consortium blockchain.

Blockchain and Artificial Intelligence

Published

Artificial intelligence (AI) was introduced in 1955 by John McCarthy

Artificial intelligence (AI) is the ability of a computer program to think, learn and mimic human thought. Introduced in 1955 by John McCarthy, artificial intelligence has several different fields of study. These fields include computer science, mathematics, psychology, and philosophy, among many others. AI is linked to several different use cases. The most prominent use cases include machine learning, supply chain optimization, speech recognition, self-driving cars, and manufacturing optimization.

Now we know a bit about AI, let’s review a few examples of how AI is improving decentralized networks like blockchain.

Cryptocurrency Trading

During the past few years, artificial intelligence has substantially increased its presence in the area of crypto trading. This is particularly true with high-frequency trading (HFT). Essentially, HFT is a type of algorithmic financial trading characterized by high speeds and high turnover rates. High-frequency trading is a perfect vehicle for cryptocurrency trading because the crypto universe has several different exchanges.

HFT uses artificial intelligence to analyze multiple technical indicators across various exchanges in an effort to take advantage of market opportunities. AI is still in its infancy stage in regard to crypto trading. Going forward, artificial intelligence will play a pivotal role within the crypto trading community. These are commonly known as trading bots.

Blockchain Security

Unfortunately, industries that find themselves in a hyper-growth phase are more susceptible to cyberattacks and malware. Without question, blockchain technology, along with digital assets, is currently experiencing an explosive rate of growth. Consequently, the blockchain industry has endured an exponential increase in malware, phishing, fraud, and digital theft. Based on data provided by industry experts, $9 million is lost to cryptocurrency scams on a daily basis.

The key to successfully thwarting a blockchain hack is to identify the threat and understand the nature of the attack as quickly as possible. Hackers are acutely aware that they must strike quickly in order to launch a profitable attack. Unfortunately, crypto exchanges have a poor track record in preventing cyber-attacks. AI-based cybersecurity systems are designed to detect a hack in real-time and dramatically increase the likelihood of stopping the attack. AI systems are far superior to traditional cybersecurity systems because AI has the ability to detect patterns from previous attacks. This information can be used to prevent future cyber threats.

Bitcoin Mining

As you know, all crypto transactions are verified and added to the blockchain by Bitcoin miners to maintain the integrity of the network. In exchange for their work, miners are rewarded with Bitcoin. Crypto mining requires energy consumption and computing power. Over the past few years, Bitcoin miners have explored the idea of using artificial intelligence to reduce energy waste and computing power to reduce costs.

A few of the largest mining companies have created AI-based systems, allowing companies to share power and increase profitability. AI algorithms have made crypto mining faster, more profitable, and more efficient. Without question, artificial intelligence will continue to play an essential role throughout the crypto industry.

How Does Blockchain Compare to Other Innovations

Probably, the most innovative discoveries of the past 100 years are the world wide web (i.e., internet) and the mobile phone. By now, both these things have become a must-have of modern human beings. Let’s look at the stats. In 1995, only 17% of USA residents were using mobile phones. By 2018, only 5% of US residents still did not have this device in use. While in 1995, only 16 million people (0,4% of the world’s population) were internet users, by 2018, this number increased to 4.2 billion, which is more than half of all people. Interestingly, during the first 5 years of the internet’s existence, only 5% of all people have found it worthy enough to use.

These numbers indicate how we interact with new technologies. As a general rule, most people are skeptical of discoveries and innovations at the early stages of their existence. Still, when the benefits of using a certain technology become obvious, it spreads all over the world with the speed of light.

Typically, it takes about 10 years before the average consumer makes an effort to research a new product or service. By this time, approximately 10% to 20% of the overall population had adopted the innovation. The remaining 80% to 90% of the population is still on the sidelines, unwilling to implement this new technology into their daily lives. Within 20 years of the new product’s existence, the majority of the population finally adopted it. Without question, consumers are very slow to implement new technologies.

Adoption of Blockchain Technology

But should we wait another 20 years to see the adoption of blockchain technology? Most likely, it will occur much faster than the internet, mobile phones, automobiles, or air travel. Why? Because once the blockchain infrastructure is in place, the old ledger system becomes useless. Therefore, soon, consumers will not have to choose between the new digital ledger and the old manual ledger. Companies that won’t migrate to the blockchain will be left behind and eventually forced out of business.

Within the next decade, blockchain technology will permeate our daily lives. For example, everyday things like voting, purchasing a vehicle or a home, visiting a medical care provider, investing in the stock market, obtaining a bank loan, going to college, or shopping at a retail establishment, will encounter blockchain technology.

Most probably, within the next five to 10 years, we will encounter blockchain technology daily. This explains why it will be exponentially larger than the internet.

Brief Summary of Blockchain In Comparison to Other Innovations

  • As a general rule, people are skeptical of discoveries and innovations.
  • It takes approximately 10 years for the average consumer to become a regular user of innovations.
  • Full adoption of a new product or service takes 20 to 30 years.
  • The adoption rate of blockchain will occur much faster.

What Is Blockchain Consensus Algorithm

Blockchain technology has many different moving parts. Hence, to operate smoothly, the architecture must be properly designed. An important piece of Nakamoto’s architectural design is the use of a consensus algorithm. 

Blockchain Consensus Algorithm in a Nutshell

In its simplest format, a blockchain consensus algorithm is a decision-making process. It is designed to assist in reaching a common decision by a group of people. Of course, in this particular scenario, the consensus algorithm involves blockchain-related solutions.

How Does it Work?

Let’s assume that 20 co-workers are asked to collaborate and offer a recommendation on a specific project. Each participant in the group will reach a decision that will provide the greatest individual benefit. The group must listen to each recommendation and decide which of them will provide the greatest overall benefit. The final recommendation must be accepted by all group members regardless of whether it offers the best solution for each individual.
