When people hear the term “blockchain,” they often think of Bitcoin. While Bitcoin was the first and is perhaps the most well-known application of blockchain technology, the potential uses of blockchain extend far beyond cryptocurrency. In this article, we’ll explore blockchain, its key features, and how it is revolutionizing various industries. We’ll also introduce you to Jackocoins, a peer-to-peer (P2P) trading platform that leverages blockchain to provide fast, secure, and high-quality trading services.

What is blockchain?

Imagine a chain made up of blocks, with each block containing a list of transactions. When a new transaction is made, it’s added to a block. Once the block is full, it’s linked to the previous block using a unique code called a cryptographic hash. This hash is like a digital fingerprint that uniquely identifies each block and links it to the next one, forming a continuous chain. Because each block contains the hash of the previous block, altering any single block would disrupt the entire chain, making it extremely difficult to tamper with the data.

Why is blockchain such a big deal?

One of the most fascinating aspects of blockchain is its immutability. Once a block is added to the chain, the information within it cannot be changed. This is because changing a block would require changing all subsequent blocks, which would require the consensus of the majority of the network participants. This feature ensures that once a transaction is recorded, it remains a permanent part of the blockchain. This immutability is achieved through cryptographic techniques that secure each block and the connections between them.

What makes blockchain technology even more exciting is its ability to cut out the middleman. In traditional systems, intermediaries like banks or clearinghouses are needed to verify and process transactions. Moreover, instead of being stored in a single location, this ledger is distributed across multiple computers, known as nodes, all over the world. This decentralized approach ensures that no single entity has control over the entire network, making it incredibly secure and transparent.

Is blockchain just about cryptocurrency?

No, its so much more than just cryptocurrency. It is the online purchase you make from Amazon, the QR code on a Pringles can, and most importantly, the digital medical records from your hospital.
Simply put, blockchain is everywhere.

Take supply chains, for example. With blockchain, every step of a product’s journey from the manufacturer to the consumer can be recorded in a transparent and immutable ledger. This means you can track the origin of your coffee beans or ensure that the seafood you’re eating is sourced sustainably. By providing an unalterable record of a product’s history, blockchain helps combat fraud, ensure quality, and build trust with consumers.

What has blockchain been doing lately?

Most people see blockchain as something complicated and futuristic, but right here and now, this technology is doing amazing things in our daily operations.

Imagine being able to track your coffee from the farm where it was grown to the store where you bought it. Blockchain makes this possible by recording every step of a product’s journey on an immutable ledger. This visibility helps combat fraud, ensures the authenticity of products, and promotes ethical sourcing practices. Companies like Walmart and IBM are already using blockchain to improve their supply chain processes and enhance transparency.

And that’s just the tip of the iceberg!

Chronicled, a medical research institution located in California, US, builds blockchain networks that demonstrate chain-of-custody. The networks help pharma companies make sure their medicines arrive efficiently, and they enable law enforcement to review any suspicious activity, like drug trafficking.

Let’s not forget our very own financial institutions. There are more ways to bank now than there were 15 years ago. Some banking institutions only require your fingerprint to authorize a transaction, right from the comfort of your home!

What makes blockchain so versatile?

Awesome is a much better word, because whatever can manage my foreign transactions and still provide real time data on my Jumia purchase, deserves nothing less. But how does blockchain do it?

Basically, there are three key features of blockchain technology, including decentralization, security, and transparency. Integrate these into any app, and you’ll operate differently. Let me explain further:


One of the coolest things about blockchain is its decentralized nature. In traditional systems, a central authority, like a bank or a government, controls the entire network. But with blockchain, there’s no central authority. Instead, the control is distributed across a network of computers, known as nodes. Each node has a copy of the entire blockchain, and they work together to verify and record new transactions. This decentralized approach means that the system doesn’t rely on a single point of failure, making it much more resilient and secure.


Security is a major highlight of blockchain technology. Each transaction on a blockchain is secured using cryptographic techniques, which are like advanced mathematical puzzles that need to be solved before a transaction can be added to the blockchain. These puzzles make it nearly impossible for anyone to alter the data once it’s been recorded. When a block of transactions is completed, it gets a unique cryptographic hash, which acts like a digital fingerprint. If someone tries to tamper with the block, the hash changes, signaling that the data has been compromised.

This means that even if a hacker tried to alter a transaction, they would need to control the majority of the network’s nodes to succeed, which is practically impossible. This combination of cryptographic security and consensus mechanisms ensures that blockchain is one of the most secure ways to record and verify transactions.


Transparency is another key feature that sets blockchain apart. Because the blockchain ledger is distributed across all the nodes in the network, everyone has access to the same data. This means that every transaction is visible to all participants, making the entire process open and transparent. It’s like having a public bulletin board where everyone can see what’s posted. This transparency builds trust among users, as they can verify transactions themselves without needing to rely on a central authority.

This level of transparency has significant implications for industries like finance and supply chain management. In finance, for example, it allows for real-time auditing and reduces the risk of fraud. In supply chains, it means that every step of a product’s journey can be tracked and verified, ensuring authenticity and quality. Consumers can see exactly where their products come from and how they were made, fostering greater accountability and trust in the system. By making information openly accessible, blockchain technology promotes a culture of honesty and integrity.
