Why Do We Need Blockchain?

Whether you are a newbie or an experienced cryptocurrency enthusiast, it can be difficult to understand why we need blockchain. However, the technology is here to stay and the future holds so much potential.

Self-sovereign identity

Using the power of blockchain technology for self-sovereign identity is a promising way to tackle data insecurity and to secure digital identities. Its decentralized structure provides better privacy and transparency.

Currently, many organizations store huge volumes of personal data. The risks of data theft and privacy breaches are increasing. It is estimated that over two billion consumer records were exposed in data breaches last year. This cost an estimated $654 billion.

Self-sovereign identity is a technology that uses decentralized identifiers to create a secure, peer-to-peer network. It relies on verifiable credentials to ensure the authenticity of the user.

While there are other digital identities on the market, they have their own setbacks. They are vulnerable to online hacks and can put sensitive information in the hands of malicious actors.

Self-sovereign identity also offers users more control over their data. Users can decide what information is shared and with whom. Unlike other digital identities, these are not stored in a wallet. They are issued to users and can be used for a variety of purposes. They can be used anywhere in the world.

There are several countries that are testing the use of self-sovereign identity. The United Arab Emirates, Malta, Estonia and Switzerland have launched pilot programmes for the use of this technology.

In addition, Bosch Research is working on a project to create an open digital ecosystem for decentralized identity management. Their goal is to allow users to verify their identity through a secure, tamper-proof public chain. They have also been awarded a $10,000 prize from Spark Money for their work on Dvara, a self-sovereign identity platform.

TNO is a national research institute in The Hague, Netherlands, and has been working on SSI technology for the last five years. The organization has been involved in a variety of SSI projects, including the Dutch Trust Network (DTN) and Trust-over-IP. It has also contributed to the W3C-CCG and Hyperledger Aries projects.

Digital payments

Currently, the digital payments industry is growing. The growth rate of digital payments is expected to rise at a CAGR of 39% over the next four years. However, digital payments are not as widespread as traditional cash transactions.

However, the industry is making progress, as more and more banks and other financial institutions are adopting this technology. It provides several benefits including a secure, fast, and low-cost means of conducting cross-border payments.

The payment industry has gone through many technological developments over the past few decades. In recent years, cashless payments have become more popular, thanks to the advent of mobile payment applications.

One of the most important benefits of blockchain is that it is secure. The data stored in an encrypted ledger cannot be changed. In addition, it is immutable. So no one can tamper with the records, making it safe for consumers. It also allows consumers to choose who they want to share their credentials with.

Another benefit of blockchain is its ability to speed up digital identity verification. Currently, banks must go through a series of steps to confirm a transaction. This includes checking the name of the person making the payment, confirming that the identity matches the profile on file, and confirming that the bank is the one making the transaction.

The process of verification is uncomfortable for consumers. The verification process may take a few hours or a few days. There are also many intermediaries involved. The verification process can cost money and cause long delays.

Blockchain can also be used to support a number of applications. This includes identity management, land registration, electoral voting, and supply chain traceability. It can also help automate business processes.

Intellectual property

Using blockchain to register and protect your intellectual property has its advantages. It can simplify and expedite the process, and provide a high level of transparency.

In the past, enforcing the letter of the law has been mostly a human affair. But a new shift in technology has spawned thousands of new ideas. Whether or not these innovations can make it into the legal system is another matter.

Using blockchain to register and protect your intellectual properties is a step up from other systems. However, case law has not yet addressed the major issues involving IP on the blockchain.

Using a digital ledger to monetize your work could be a game changer. But it will only do so if the information is accurate. It also could save you time and money.

A digital business service called WIPO PROOF is designed to make this possible. It offers a date and time-stamped digital fingerprint of any file.

It is no wonder that industries ranging from the food industry to diamonds are using blockchain technology. While the system may not be ready for prime time just yet, it is already providing benefits.

The blockchain is also a great way to prove the first use of your intellectual property. For example, if you have a patent, you can use it to claim ownership and establish the rights of your invention. You can then manage your sales through a platform that is automated and secure.

One of the other awesoems of the blockchain is its ability to be tamper-proof. In fact, blockchain technology has the potential to create an official register of all intellectual property.

The blockchain also offers the chance to create a smart contract, which can automate the assignment of rights, simplify the complexities of a sales contract, and streamline the complexities of an IP transaction.


Whether a public blockchain can scale to a large number of transactions and computations is the fundamental challenge. Several researchers are attempting to address the issue in detail.

Scalability of public blockchains is a combination of several parameters. The number of nodes, the storage capacity of the network, the consensus model, and the amount of bandwidth the network supports are all factors that determine the efficiency of a public blockchain.

The size of blocks affects the throughput and latency of the network. Block size is also a factor that influences the consensus model. Several solutions have been proposed to address the scalability issue.

A scalable and secure network will require a large number of active participants. In addition, a scalable network will increase the cost of running a node. A solution to the scalability issue should be feasible and implementable.

Public blockchains have huge storage requirements. In addition, the storage requirement grows with the number of nodes. One solution to this problem is increasing the number of partial nodes. Partial nodes only store a part of the blockchain.

Another solution to the scalability issue is adding shards on demand. Each shard is a separate block that holds a unique set of smart contracts. In a n-node public blockchain network, each block would be replicated n times.

The amount of storage required by a public blockchain depends on the types of application. A vehicle tracing database of 700 cars for 24 hours requires a storage capacity of around 4.03 GB. Increasing the size of blocks increases throughput, but also increases block propagation time.

The size of the blocks also affects the amount of computational energy used. The amount of energy required for computations is also dependent on the consensus model.


Using a blockchain to provide transparency can improve the quality of goods. Creating a decentralized immutable record of every transaction can also increase trust among end-market users.

It can also help businesses understand how subcontractor relationships are working. It can also prevent profit losses from counterfeit and gray market trading. It can also track donated money, making sure it gets to the intended recipients. It can even simplify sharing health information.

For example, using a blockchain to track donations to charity can help ensure the money gets where it’s supposed to. It can also reduce fraud involving high-value goods.

Another way to improve transparency is to reduce information asymmetries. Many suppliers’ business models require that they have access to different pieces of information. This is problematic because it could prevent them from joining a blockchain-based platform. It can also lead to issues for customers and competitors.

For example, it can be difficult to track the route of a container shipment. This is especially difficult for high-value goods. It’s also more difficult to track the charge for a large amount of unprocessed groceries.

One way to overcome the transparency challenge is to create a self-sovereign identity. A self-sovereign identity is a type of digital identity that can be trusted independently. Using a blockchain is one way to create a self-sovereign digital identity.

A second way to solve the transparency challenge is to use a permissioned blockchain. In a permissioned setting, a trustless system is likely to be adopted by stakeholders.

The use of a blockchain to provide transparency can improve the transparency of supply chains. A blockchain-based platform could also reveal information about a company’s relationships with other businesses. It would also reduce the complexity of reporting and governance.
