Blockchain: What you need to know

What Is a Blockchain?

Blockchain is a way to securely record transactions into digital blocks and store them in a digital ledger. Blockchain has the potential to fundamentally change the way we conduct transactions, manage records and exchange assets. Blockchain will transform financial services, supply chain management and healthcare, among other areas. Blockchain technology can be used to create a permanent, public “ledger” of transactions between two parties without requiring any middlemen or central authority to authenticate or oversee the activity.

Blockchain offers the possibility of reducing costs for businesses by making transaction settlements faster and more efficient. Blockchain’s decentralized structure also provides specific benefits for activities such as voting and crowdfunding where people need an alternative to traditional models that rely on one central authority or individual. Blockchain may spark powerful new economic opportunities for some of the world’s poorest people by providing them with access to the global financial system.

How Does Blockchain Work?

A blockchain is essentially a digital ledger of transactions, events or data that is distributed across a network of computers. Blockchain technology uses cryptography to secure and verify these transactions. Blockchain is different from other digital ledgers because it is decentralized, meaning it is not controlled by anyone central authority.

Instead, the ledger is distributed across a network of computers, known as nodes, each of which has a copy of the entire ledger. When a new transaction or event occurs, it is added as a block to the end of the ledger. Once a block has been added to the ledger, it cannot be altered or removed without changing all subsequent blocks in the chain. This makes Blockchain a more secure and transparent way to store data.

Why Blockchain Is Gaining Traction?

Blockchain has been around for about a decade, but it is only recently that the technology has begun to gain traction. There are several reasons for this, including:

-The growing interest in cryptocurrencies such as Bitcoin and Ethereum, which are built on Blockchain technology.

-The increasing awareness of the benefits of Blockchain technology, including its transparency, security and efficiency.

-The development of new Blockchain platforms and applications that make the technology more accessible to businesses and consumers.

What Are the Benefits of Blockchain?

There are many benefits of Blockchain technology, including:

-Security: Blockchain is a very secure way to store data. Blockchain uses cryptography to secure transactions and prevent tampering.

-Transparency: Blockchain is a transparent way to store data. Transactions on the Blockchain are visible to everyone on the network.

-Efficiency: Blockchain is a more efficient way to conduct transactions. Blockchain can automate many processes, such as settlements and record keeping.

-Decentralization: Blockchain is a decentralized technology, which means it is not controlled by any central authority. This makes it more democratic and accessible.

What Are the Disadvantages of Blockchain?

There are also some disadvantages of Blockchain technology, including:

-Scalability: Blockchain is still a new technology, and it has not been tested at scale. It is unclear how well Blockchain will perform when it is used by millions of people.

-Interoperability: Blockchain platforms are still not compatible with each other, which makes it difficult to use Blockchain for cross-border transactions.

-Regulatory uncertainty: The regulatory environment for Blockchain is still uncertain, and businesses are hesitant to invest in the technology until there is more clarity.

How Might Blockchain Be Used in the Future?

There are many possible applications of Blockchain technology in the future, including:

-Currency: Blockchain can be used to create digital currencies such as Bitcoin and Ethereum. These currencies can be used to conduct transactions without the need for a central authority.

-Asset Management: Blockchain can be used to manage and track assets such as securities, land titles and digital assets.

-Supply Chain Management: Blockchain can be used to track the movement of goods through supply chains. This would make supply chains more efficient and transparent.

-Voting: Blockchain can be used to create a secure and tamper-proof voting system. This could help to increase confidence in the electoral process.

-IoT: Blockchain can be used to connect devices in the Internet of Things (IoT). This would allow devices to share data and conduct transactions without the need for a central authority.

Blockchain is a new and exciting technology with the potential to transform the way we live and work. However, there are still many challenges that need to be addressed before Blockchain can reach its full potential. businesses and consumers alike should keep an eye on Blockchain, as it is likely to play a big role in the future.

Transparency

Transparency is a quality of being open, clear and straightforward.

=>Transparency in business refers to the degree to which necessary information about an organization’s activities is available from one point within the organization (or from outside observers) so as not to be hidden or obscure. Transparency also means that accounts are monitored for accuracy and probity.

=>In our daily lives, transparency means we see through something such as glass or water without difficulty or distortion. It is simply visibility without obstruction, seen by all sides with no secrets.

=>Transparency is also a key part of the trust. When we are transparent with others, they trust us more because they know what we are doing and why. We can be open with them about our mistakes, intentions, and feelings, and they can do the same with us.

=>When something is transparent, it usually has nothing to hide. And that is the goal for most businesses – to be open and have nothing to hide from their customers or stakeholders. This way, everyone can work together towards the same goal of success.

Security

Blockchain technology was originally created as a way to track Bitcoin ownership.

Cryptography is used in Blockchain technology to make all of the transaction ledgers in the system public so that no one entity can control them all at once. This makes the system more secure as it is difficult to hack into multiple computers at once.

=>Hacks can occur when a business’s computer systems are compromised by thieves who want to steal information or money. Hackers use a variety of methods to gain access to computer systems, including stealing passwords and infecting systems with malware.

=>When a business’s computer systems are hacked, the thief can access sensitive information such as customer data or financial records. They can also steal money from the business’s bank account or use the company’s credit card to make fraudulent purchases.

=>A business needs to have strong security measures in place to protect itself from hackers. These measures can include installing firewalls, using encryption, and requiring employees to use strong passwords.

Fraud prevention

Blockchain technology can also be used to prevent fraud.

=>When a transaction is made, it is stored in a block of data that includes a timestamp and information about the transaction. The block of data is then added to the blockchain, which is a digital ledger of all the transactions that have been made.

=>The blockchain is transparent and secure, so it is difficult for anyone to tamper with the data. This makes it difficult for fraudsters to commit fraud because they would need to change the data in all of the blocks in the chain, which would be very difficult to do without being detected.

=>Blockchain technology can be used to track other things besides financial transactions. For example, it can be used to track the provenance of food or drugs, or to prevent fraud in the voting process.

Efficiency

Blockchain technology is more efficient than traditional systems because it doesn’t require a third party to verify transactions.

=>In traditional systems, such as banks, a third party (such as a central bank) is needed to verify and approve all transactions. This can slow down the process and make it more expensive.

=>With Blockchain technology, transactions are verified by the network of computers that maintain the blockchain. This means that transactions can be approved much faster and at a lower cost.

=>The efficiency of Blockchain technology is one of the reasons why it is being adopted by more and more businesses. It can help businesses save time and money, and it can make the process of doing business more efficient.

Blockchain offers many benefits to businesses, including transparency, security, fraud prevention, and efficiency. This technology is still in its early stages, but it has the potential to revolutionize the way we do business. If you want to learn more about Blockchain, contact us today.

Bitcoin vs. Blockchain

Stuart Haber and W. Scott Stornetta were the first to describe blockchain technology in 1991. They wanted to create a system that would prevent document timestamps from being altered. It wasn’t until nearly two decades later that the first application of blockchain technology was realized. This was due to W. Scott Stornetta and Stuart Haber, who were researchers who wanted to create a system where document timestamps could not be altered.

Blockchain is the basis of Bitcoin’s protocol.

It is important to remember that Bitcoin uses blockchain to transparently record payments. However, blockchain can theoretically be used to immutably store any number of data points. This could include transactions, votes in elections, product inventories and state identifications. Deeds of homes can also be used.

Tens of thousands of projects currently seek to use blockchains to support society in many ways beyond just recording transactions. For example, to secure voting in democratic elections. Fraudulent voting will be much more difficult due to blockchain’s immutability. A voting system could be designed so that every citizen of a country is issued one token or cryptocurrency. The candidate would be assigned a unique wallet address and voters would send their tokens or crypto to that address. Blockchain’s transparent and traceable nature would eliminate the need to count votes and allow bad actors to alter physical ballots.

Blockchain vs. banks

Blockchains are being touted as a disruptive force in the financial sector, especially when it comes to banking functions and payments. But banks and decentralized Blockchains are very different.

Let’s see how banks differ from the blockchain. Let’s look at the banking system in comparison to Bitcoin’s implementation.

What are the uses of blockchains?

We now know that blocks on Bitcoin’s Blockchain store information about monetary transactions. There are currently more than 10,000 cryptocurrency systems that run on blockchain. Blockchain is a reliable method of storing transaction data.

Walmart, AIG and Siemens are just a few of the companies that have already implemented blockchain. IBM, for example, has its Food Trust blockchain that tracks the route food products take to reach their destinations.

This is why? There have been many outbreaks of E.coli, salmonella and listeria in the food industry. Inadvertently introducing hazardous substances to foods has also led to numerous other problems. It has taken weeks in the past to determine the of these illnesses or what caused them.

Blockchain allows brands to track the route of food products from their origin through every stop they make and then finally to their destination. If food is found to have been contaminated, it can be tracked back to its through all stops. These companies can now see all other food it has come into contact with. This allows for the detection of the problem much sooner, potentially saving lives. This is just one example of blockchain implementation in practice. There are many more.

Banking and Finance

Banking is perhaps the most likely industry to reap the benefits of integrating blockchain technology into its business operations. Banks are only open during business hours, which is usually five days per week. If you attempt to deposit a check Friday at 6 p.m. you’ll likely need to wait until Monday to see the money in your account. Even if your transaction is made during business hours, it can take up to three days for the transaction to be verified due to the volume of transactions banks have to settle. Blockchain is a system that never sleeps.

Consumers can have their transactions processed within 10 minutes by integrating blockchain into their banks. This is regardless of whether it’s holiday time or what time of the week it is. Banks can also exchange funds faster and more securely with blockchain. Stock trading, for instance, can take up three days to settle and clear. If trading internationally, it may take longer. This means that money and shares will be frozen for that time.

Banks can face significant risks and costs due to the large sums involved.

Currency

Blockchain is the foundation for cryptocurrencies like Bitcoin. Federal Reserve controls the U.S. Dollar. The Federal Reserve is technically in control of currency and data. The client’s personal information could be at risk if their bank is hacked. The currency value of the client’s money could be at risk if their bank fails or if they live in unstable countries. In 2008, several banks that were insolvent were saved by the government. These were the fears that Bitcoin was created and developed.

Blockchain allows Bitcoin and other cryptocurrencies to function without the intervention of central authority by spreading their operations over a network. This reduces the risk and eliminates transaction fees. It can be used to give people in unstable countries or with poor financial infrastructures a stable currency that can accept more applications and allows them to do business with more institutions and individuals.

For those without state identification, it is particularly important to use cryptocurrency wallets as a way of paying or saving. Certain countries might be in war zones or lack the infrastructure necessary to provide identification. These countries might not have savings or brokerage accounts, and therefore no safe way to store wealth.

Healthcare

Blockchain can be used by healthcare providers to store patients’ medical records securely. A medical record can be signed and generated on the blockchain. This gives patients the assurance that it cannot be altered. This private key could be used to encode and store personal health records on the blockchain.

Property Records

You will be familiar with the inefficiency and burden of recording property rights if you’ve ever worked in your local Recorder’s Office. A physical deed needs to be given to a local government employee at the recording office. The county’s central database and public Index will then be manually entered it. If there is a property dispute, the claims must be reconciled to the public index.

This is a time-consuming and costly process. It is also susceptible to human error. Each inaccuracy can make tracking property ownership more difficult. Blockchain can eliminate the need to scan documents and track down physical files at a local recording office. Owners can be confident that the deed is correct and permanent if it is stored on the blockchain.

It can be difficult to prove ownership in war-torn areas or areas without a financial or government infrastructure. A group of people in an area that is affected by war can leverage blockchain to establish transparent and clear ownership lines.

Smart Contracts

A smart contract can be a code built into the blockchain that facilitates, verifies, or negotiates a contract agreement. Smart contracts are subject to a set conditions that users must agree to. These conditions must be met before the agreement can be executed.

Imagine a tenant who wants to rent an apartment with a smart contract. After the tenant has paid the security deposit, the landlord will give the tenant the key code for the apartment. The smart contract would receive the agreement from both the landlord and tenant. It would then exchange the code for security deposit and hold on to it. The smart contract will refund the security deposit if the landlord fails to provide the code before the lease begins. This would eliminate fees and other processes that are usually associated with hiring a notary or third-party mediator or attorney.

Supply Chains

Like the IBM Food Trust example above, suppliers can use Blockchain to track the origins and purchase of materials. This would enable companies to verify not only the authenticity of their products but also common labels like “Organic,” “Local,” and “Fair Trade”

Forbes reports that the food industry is adopting blockchain technology to track and monitor the safety and path of food during the entire farm-to-user journey. 4

Voting

Blockchain could be used to facilitate modern voting systems, as mentioned previously. Blockchain voting has the potential to reduce election fraud and increase voter turnout. This was demonstrated in November 2018 in West Virginia. 5 Voting using blockchain would be nearly impossible to alter. Blockchain protocol would ensure transparency and provide officials with almost instant results. This protocol would eliminate the need to recount or any concern about fraud threatening the election.

Blockchain: The pros and cons

Blockchain’s potential to be a decentralized record-keeping system is nearly limitless despite its complexity. Blockchain technology could have many other applications than those listed above. It can provide greater privacy, heightened security, lower processing fees, and less errors. There are some drawbacks.

Blockchains have many benefits

Accuracy of the Chain

A network of thousands of computers approves transactions on the blockchain network. This eliminates nearly all human involvement in the verification process. It results in less human error, and a more accurate record of information. Even if one computer made a mistake in computation, it would not affect the rest of the blockchain.

Cost reductions

A bank is usually paid to verify a transaction. A notary may sign documents or a minister can perform marriage ceremonies. Blockchain eliminates the need to verify third parties and all associated costs. Because banks and payment-processing firms have to process these transactions, small fees are charged by business owners when they accept credit card payments. Bitcoin on the other hand has no central authority and is subject to a limited number of transaction fees.

Decentralization

Blockchain doesn’t store any information in a central place. Instead, the blockchain information is copied and distributed across a network. Every computer on the network updates their blockchain whenever a block is added to it. Blockchain is easier to manipulate if it is distributed across the network rather than stored in a single database. A hacker could only access a single copy, and not the entire blockchain, if they had access to it.

Efficient Transactions

Transactions made through a central authority may take up to several days to settle. For example, if you try to deposit a Friday night check, you might not see the funds until Monday morning. While financial institutions are open during business hours five days a semaine, blockchain works 24 hours a days, seven days per week, and 365 consecutive days. Transactions can be done in a matter of minutes and are considered secure within a matter of hours. This is especially useful for cross border trades which can take longer due to time zone issues and the fact all parties must confirm payment processing.

Private Transactions

Many blockchain networks function as public databases. This means that anyone can access the transaction history of any network. While users can view transaction details, they are not able to access the identifying information of those who made them. A common misconception is that blockchain networks such as bitcoin are anonymous. In reality, they are confidential.

 

A user can make a public transaction by entering their unique code, which is known as a public key. This information is stored on the blockchain. Their personal information is not. A person can only make a Bitcoin purchase on an exchange that requires identification. However, their identity is linked to their Blockchain address. But a transaction, even if tied to a name, does not reveal any personal data.

Secure Transactions

The blockchain network must verify the authenticity of a transaction once it is recorded. The transaction details are verified by thousands of computers connected to the blockchain network. Once a computer validates the transaction, it is added into the blockchain block. Each block on the blockchain has its own hash and the hash of any block before it. If the information on a particular block is changed in any way, its hash code will change. However, the hash code of the block following it would not. This discrepancy makes modifying information on the blockchain extremely difficult.

Transparency

Many blockchains are open- software. This means anyone can see its code. Auditors have the ability to inspect cryptocurrencies such as Bitcoin for security. This means that it is not clear who or what controls Bitcoin’s code and how it is edited. Anyone can suggest upgrades or changes to the system. Bitcoin can be updated if a majority of network users agree that the upgraded version of the code is valid and worth the effort.

Bank for the Unbanked

The most important aspect of blockchain and bitcoin is its ability to be used by anyone regardless of their ethnicity, gender, or cultural background. The World Bank estimates that 1.7 billion people do not have any bank accounts, or other means to store their wealth or money. Most of them live in developing countries where cash is scarce and the economy is still in its infancy.

They often make a small amount of money, which is then paid in cash. These people then have to hide the cash in safe places in their homes and other areas of their lives, making them vulnerable to theft or violence. The keys to a bitcoin wallet are stored on paper, on a cheap phone or can even be memorized. These options will be more difficult to conceal than a small amount of cash under a bed.

The future blockchains are looking for ways to not only store wealth but also to store property rights and medical records.

Blockchains have their drawbacks

Technology Cost

Blockchain can help users save money on transaction fees but it is not free. The PoW system, which is used by the bitcoin network to verify transactions, requires a lot of computational power. 8 In real life, the power of the millions upon millions of bitcoin network computers is comparable to the annual consumption of Norway and Ukraine.

 

Users continue to increase their electricity bills despite the high cost of mining bitcoin. This is because they need to verify transactions on the blockchain. Because miners can add a block of bitcoin to the blockchain and are rewarded with enough bitcoin that it makes their effort worthwhile. However, miners must be compensated or incentivised to verify transactions on blockchains that don’t use cryptocurrency.

These problems are being addressed by solutions. Bitcoin-mining farms, for example, can be set up to make use of excess natural gas from fracking sites or solar power.

Speed and data inefficiency

The inefficiencies that blockchain can bring to bear on Bitcoin are well-executed by the case of Bitcoin. 9 It takes approximately 10 minutes to add a block to Bitcoin’s PoW network. At this rate, the blockchain network can only handle seven transactions per second (TPS). While other cryptocurrencies like Ethereum perform better than Bitcoin, their capabilities are still limited by the blockchain. For context, Legacy brand Visa can process 65,000 TPS. 

This issue has been solved for many years. Blockchains boasting over 30,000 TPS are available at the moment

Another issue is that each block cannot hold more data. The block-size debate is one of the most important issues to consider for future scalability of Blockchains.

Illegal Activity

The blockchain network’s confidentiality protects users against hacks and preserves their privacy. However, it allows for illegal trading and other activity. Most cited example of blockchain being used to illicit transactions is the Silk Road. This online marketplace for illegal drug and money laundering was active from February 2011 through October 2013. It was shut down by FBI agents.

The dark Web lets users buy and sell illegal goods anonymously. The current U.S. regulations require that financial service providers obtain customer information when opening an account. They also need to verify each customer’s identity and confirm that they are not on any terrorist list. his system allows anyone to access financial accounts, but criminals can transact more easily. Many argue that cryptocurrency has many positive uses, such as banking the unbanked, and also allows criminals to transact more easily, especially since most of the illegal activities are still done through untraceable cash.

Although Bitcoin was initially used for these purposes, its transparency and maturity as an asset have seen illegal activity migrate away from Bitcoin. Today, only a small percentage of Bitcoin transactions is illegal.

Regulation

Many people involved in the crypto industry have expressed concern about government regulation of cryptocurrencies. As Bitcoin’s decentralized network grows, it becomes increasingly difficult and almost impossible to stop it. However, governments could make it illegal for anyone to own or participate in cryptocurrencies.

As large companies such as PayPal allow ownership and use of cryptocurrency on their platforms, this concern has become less important.

What is a Blockchain Platform?

The blockchain platform allows developers and users to make new uses of existing blockchain infrastructure. Ethereum is one example. It has a native cryptocurrency called ether ( ETH). But, the Ethereum blockchain allows for the creation of smart contracts and programmable tokens that can be used in initial coins offerings (ICOs),, as well as non-fungible tokens. All of these are built around the Ethereum network and protected by nodes.

What are the Numbers of Blockchains?

Every day, the number of active blockchains grows at an ever-increasing rate. There are over 10,000 active cryptocurrencies that are based on blockchain as of 2022. There are several hundred additional non-crypto currency cryptocurrencies.

What is the difference between a private and public blockchain?

A public blockchain is also known as an open, or permissionless, blockchain. Anyone can join the network and create a node. These blockchains are open and must be protected with cryptography and a consensus system such as proof of work (PoW) because of their open nature.

For a private or authorized blockchain, however, each node must be approved before it can join. Nodes are trusted so layers of security don’t need to be as strong.

Who invented blockchain?

W. Scott Stornetta and Stuart Haber, two mathematicians, first proposed blockchain technology in 1991. Nick Szabo suggested using a Blockchain to secure a digital payment system. 

What’s next for Blockchain?

Blockchain is making waves, thanks to many practical applications that have been implemented and explored. Blockchain is a popular buzzword in the country and will make government and business operations more efficient, secure and cost-effective. There will be fewer middlemen.

As we enter the third decade with blockchain technology, it is no longer a matter of whether legacy companies will adopt the technology. It’s more about when. We see an increase in NFTs and tokenization of assets. Blockchain will experience significant growth in the coming decades.
