15 Applications for Blockchain Technology The Motley Fool

Another way to invest in blockchain technology is to invest in startups built on blockchain technology. Finally, there is always the option to invest in pure blockchain technology. Also sometimes known as hybrid blockchains, permissioned blockchain networks are private blockchains that allow special access for authorized individuals. Organizations typically set up these types of blockchains to get the best of both worlds, and it enables better structure when assigning who can participate in the network and in what transactions. A blockchain is a distributed, immutable, and decentralized ledger at its core that consists of a chain of blocks and each block contains a set of data.

A blockchain can maintain title rights because, when properly set up to detail the exchange agreement, it provides a record that compels offer and acceptance. The implementation of the blockchain within bitcoin made it the first digital currency to solve the double-spending problem without the need of a trusted authority or central server. The bitcoin design has inspired other applications and blockchains that how to build a blockchain are readable by the public and are widely used by cryptocurrencies. This naturally led to the emergence of various types of cryptocurrency, such as Bitcoin, which builds on a technology commonly known as Blockchain. To attain the desired objective, after presenting an inevitable, brief overview of Blockchain technology, the collected papers have closely been analyzed along seven key research questions.

Individual control of data

This means that if you wanted to, you could track a bitcoin wherever it goes. A blockchain allows the data in a database to be spread out among several network nodes—computers or devices running software for the blockchain—at various locations. This not only creates redundancy but maintains the fidelity of the data. For example, if someone tries to alter a record at one instance of the database, the other nodes would prevent it from happening. This way, no single node within the network can alter information held within it. Transactions follow a specific process, depending on the blockchain they are taking place on.

  • The security offered by blockchain technology is a largely tamper-proof method of data storing and sharing, with the owner traceable throughout the block height.
  • Blockchain-based smart odometers integrated with GPS can completely solve this issue.
  • Financial institutions are exploring how they could also use blockchain technology to upend everything from clearing and settlement to insurance.
  • This inherently secure nature of distributed blockchain technology means that it prevents damage to the entire blockchain shared database and can cut off a hacking attempt at one block.
  • Satoshi Nakamoto is, in fact, a pseudonym and the author of the Bitcoin whitepaper that appeared in 2008.
  • This would make it easy to integrate various flows of transactions across firms.

Opponents say that permissioned systems resemble traditional corporate databases, not supporting decentralized data verification, and that such systems are not hardened against operator tampering and revision. Nikolai Hampton of Computerworld said that “many in-house blockchain solutions will be nothing more than cumbersome databases,” and “without a clear security model, proprietary blockchains should be eyed with suspicion.” Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree. Each block includes the cryptographic hash of the prior block in the blockchain, linking the two. This iterative process confirms the integrity of the previous block, all the way back to the initial block, which is known as the genesis block . To assure the integrity of a block and the data contained in it, the block is usually digitally signed.

Blockchain Applications in Other Industries

To be sure, it is a life-changing technology that will bring great things over the years to come. Each block in the chain is chronologically connected to previous blocks and synched with the network nodes. This means that changing the data in one block would mean having to reverse all previous blocks before it, making it very hard to tamper with–very hard, although not entirely impossible. The immutable nature of blockchain, and the fact that every computer on the network is continually verifying the information stored on it, makes blockchain an excellent tool for storing big data. As stated earlier, the encryption that is central to blockchain makes it quite useful for record management because it prevents duplicates, fraudulent entries, and the like.

Why blockchain technology is used

Any attempts to copy data are immediately noticeable when they misalign from every other users’ code copies. Most people have heard something about blockchain technologies, likely in relation to the transaction of cryptocurrencies. Blockchain as we currently know it was introduced with the first ever cryptocurrency — Bitcoin — in 2009, and has since taken over the cryptocurrency market. However, as nice as it sounds to bring money to the people, this is easier said than done.

Manage Business and Software Risk

Unlike cash, crypto uses blockchain to act as both a public ledger and an enhanced cryptographic security system, so online transactions are always recorded and secured. Blockchain-based digital identities will be powerful across multiple industries, consumer applications, and within the public sector. Tenant and investor identities from mutualized blockchain-based KYC/AML procedures can streamline background checks, reduce costs, and increase security.

Why blockchain technology is used

In the food industry, blockchain can help ensure food safety and freshness, and reduce waste. In the event of contamination, food can be traced back to its source in seconds rather than days. Blockchain creates an audit trail that documents the provenance of an asset at every step on its journey. In industries where consumers are concerned about environmental or human rights issues surrounding a product — or an industry troubled by counterfeiting and fraud — this helps provide the proof.


There are many types of blockchain platforms for different needs, such as Ethereum, Hyperledger, etc. Private blockchains are only open to selected people, while public blockchain is open to the general masses. Blockchain is a shareable ledger that records transactions and is difficult to modify or change. In this blockchain program, you will learn how to master blockchain concepts, techniques, and tools like Truffle, Hyperledger, and Ethereum to build blockchain applications and networks. Although we just skimmed the industry-wide potential of blockchain applications in this article, the career potential in this field is growing exponentially.

Documentation can be stored on the blockchain along with transaction details, eliminating the need to exchange paper. There’s no need to reconcile multiple ledgers, so clearing and settlement can be much faster. Your data is sensitive and crucial, and blockchain can significantly change how your critical information is viewed.

Motley Fool Investing Philosophy

Health-related organizations can create a centralized database with the technology and share the information with only the appropriately authorized people. In all of these cases , leveraging blockchain technology by creating Smart Contracts will enable any organization to ‒ both — improve operations and keep more accurate records. The smart contracts are what allows the blockchain to be used for more than just a database. Traditional blockchains like Bitcoin and Ethereum, use a consensus mechanism called PoW, which requires computational power and electricity to solve complex mathematical puzzles. This energy-intensive process has raised concerns about the environmental impact of blockchain technology because it produces carbon emissions and consumes a huge amount of electricity.
