“Man is born free and everywhere he is in chains,” this opening sentence from philosopher Jean-Jacques Rousseau’s ‘The Social Contract’, written over 350 years ago, finds resonance even today.

Businesses, integral to any social contract throughout history, want the freedom to transact without an intermediary. Business leaders and visionaries, usually realistic and pragmatic, dream of transactions happening in the presence of an entity or a mechanism that all parties can trust, at nominal cost. After a long and impatient wait, the answer to this pressing puzzle was discovered in 2009. It is uncanny that the new radical way of perceiving the world of transactions is named blockchain technology.

Blockchain moves transactions to a distributed ledger (an entity storing transaction record in a physical form; be it paper, hard drives or bank software, etc) across a computer network, making any central authority redundant. Its game-changing benefit is the immutability of transactions, once finalized and recorded on the blockchain. This is what endows it with trust, the most valuable ‘currency’ across history.

Having said all this, why is blockchain important for the future?

The blockchain is a bouquet of revolutionary technologies that open up infinite possibilities to run your business based on the way you structure transactions. In just over a decade since its discovery, Blockchain 4.0 is in the works. Combined with Web 3.0, these technologies will fundamentally change our perceptions on how business is done.

We can expect the world to be a starkly different place within a decade. Nation states may lose their hold on levers of power, with their writ on allowing or disallowing transactions of any kind — not just monetary — being usurped by blockchains.

A version of democracy will develop within a single blockchain, and between distinct kinds of blockchains; the overwhelming majority, as of today, are public.

The mechanism powering all blockchains is algorithm-driven, which provides a clear layer of accountability and offers the flexibility to develop a fount of applications.

For instance, type Axie Infinity on your device and you get to play a blockchain-based game. IBM has built a Food Trust around blockchain and is promising to herald a new era in the world’s food supply.

Blockchain technology will soon be a tangible part of our daily lives (on the scale of the internet or the smart phone) and this makes it critical for us to stay updated on all its facets. Its prime benefit is building trust and allowing collaboration among hitherto disparate businesses, resources, or lifestyles. If we use it right, we can create magic that is bigger than any the world has ever seen.

Here's a status check on blockchain. Today, we have the capacity to take any information (transactions are just one kind) online, distribute and access it, when necessary, within a network we choose to trust, without any kind of coercion or paying any cost for intermediation.

To date, almost all business transactions needed a central authority as an intermediary to validate and verify the exchange of value. Yet, the process that has ledgers and contracts as the nuts-and-bolts of the transaction is unfair due to uncertainty over rules, the high intermediary charges, and so on.

Training Module IV: Key Blockchain Components

In Training Module IV, ‘Key Components of a Blockchain’, we learn of the basic structure of the much-hyped block. The critical thing to remember that a block is the result of finding a unique question to create it (technically referred to as mining), and that each block in any chain includes all transactions.

As with every technology, there are ideas that make it special. Here, it is the block and the way these align to make a chain. The process is super-smooth, though energy-intensive. We study the basic structure of a block, a mere 1 MB in computing storage, and how the hash function (the question) is necessary to its creation.

Training Module V: Consensus Mechanisms in Blockchain

Consensus Mechanisms in Blockchain, our Training Module V, takes you into the intricacies of achieving an agreement, within a blockchain, on the transactions that are to be verified and validated. This consensus is actually an algorithm that securely updates data on the blockchain without the need for intermediaries.

The first of these consensus mechanisms, in use since the technology was discovered is the Proof of Work, and holds relevance even today. Each consensus mechanism is evaluated on eight variables, of which transaction speed and election criteria for miners are fundamental to the quality of the blockchain.

The blockchain network now needs a mechanism to ensure that transactions on it are acceptable to everybody, without any intermediary. We also need a system to ensure that the network, at all times, is free of double-spending. The import of all this is to create a new block to complete transactions on the blockchain network.

We may perceive these set of conditions as the substitute for an intermediary. The genius of blockchain, however, lies in its ability to generate a new block for each transaction on the network. Its second ‘wow!’ factor is having each of these blocks store all transactions, and attaching to the chain, elongating it in the process.

Keep in mind that this creation of a block and its attachment to the chain is taken care of under a previously agreed-upon consensus mechanism.

Training Module VI: Benefits and Challenges of Blockchain

Click here to get complete access to the comprehensive Blockchain Technology deck

Next up, in challenges and benefits before the technology, we learn that their decentralized nature, immutability, and low cost makes it unique. Governance, the system of key management (akin to today’s passwords for access to funds), is a big challenge, but research on solutions is on at a rapid pace.

Click here to get complete access to the comprehensive Blockchain Technology deck

Benefits of the technology range from individual control over data to significant reduction in cost of doing business. Our module lists 12 benefits.

Security and privacy of data is also assured to a higher degree. Tokenization could also be a game-changer as assets and ownerships are divided into multiple shares in the form of tokens.

In challenges, scalability is an issue, but work is on to overcome it. The irreversible nature of the transaction could also lead to heartburns, as more people adopt blockchain. There will always be some percentage of those on the network, who lose their private key and will never be able to use their funds. Getting a consensus mechanism agreed upon from all nodes (users) is a difficult task.

As with traditional business organizations where ownership decides category, a blockchain is classified on the basis of accessibility. These are Private, Public, Hybrid, and Consortium blockchains.

A private blockchain appears to be a bit of a contradiction, as a single organization controls it. Yet, it can offer partial decentralization. A public blockchain is, of course, open to all with full transparency. To be sure, high consumption of power plagues the public blockchain, especially if it uses the Proof of Work consensus mechanism, but it is good for user empowerment.

In a consortium blockchain, more than one organization operates a blockchain network. It has low transaction costs, but lacks a stable economic model. In a hybrid blockchain, which is a combination of public and private, one can again save on costs. Flexibility with scalability and transparency, however, remain two key challenges.

In decentralization, the blockchain transfers decision-making authority to a single distributed network to it, ensuring that there is no single-point of failure. In the module, we also learn to build each of these three systems, to accomplish specific, pre-defined tasks.

We guide the trainer to clear misconception of participants around the blockchain technology. The two beliefs most resistant to change are:

Every blockchain is public
Blockchain is the same as cryptocurrency

Training Module IX: Types of Attacks in Blockchain

In Training Module IX, we put the spotlight on shoring up businesses’ defenses against attacks that blockchain networks suffer, with the ultimate aim of the looters being to capture the chain and manipulate transactions.

The manifestation of this is in the form of 51% attacks, when an individual or organization takes over more than half of the validation power, manipulating transactions, and settlements of nodes (could be you, me, or any of our readers).

The second attack we study is Distributed Denial of Service; another is the routing attack, as also the User Wallet Attack. The module also covers the Sybil and the Mining Pool Attack.
