A blockchain is a worldwide distributed ledger that records transactions on thousands of computers. These are saved in a way that makes it impossible to modify them later. In a cost-effective and transparent manner, blockchain technology improves the security and speed of information exchange. It also eliminates the requirement for third parties whose primary role was to provide transaction trust and certification (such as notaries and banks).
The significance of blockchain has sparked the interest of corporations across many industries in companies developing blockchain services with the banking sector now being the most engaged. Blockchain has led in the creation of thousands of new jobs and businesses, ranging from mobile payment solutions to health care applications. A block represents the digital data or information that is recorded in a blockchain. Cryptography, which is simply a way of keeping information separate and secure, is used to link blocks together. The accumulation of these blocks forms a chain that functions similarly to a public database.
Blockchain, which was created as the basis for Bitcoin, has quickly acquired prominence for its capacity to create a huge, globally distributed ledger that can record anything of value across millions of machines.
Blocks of transactions are organized and recorded in a chain of blocks (thus the term "blockchain"). Cryptography safeguards the connections between blocks and their contents, prohibiting the erasure or falsification of previous transactions. The ledger and transaction network can be trusted without a central authority or an intermediary.
The blockchain's ability to record, store, and move any type of asset with great ease, automation, and decentralization has grabbed the interest of startups and the financial services industry in general.

Blockchain consulting is becoming much more accessible for businesses because of the popularity of blockchain technology. Blockchain has the ability to improve cross-border payments by reducing costs and removing many of the traditional middlemen. At the same time, it would lower the cost of money transfers.
Until now, remittance costs ranged from 5 to 20%. Blockchain technology has the potential to cut transaction costs from 2% to 3% of the total amount and deliver guaranteed, real-time cross-border transactions.
Santander was the first bank in the United Kingdom to use blockchain to send live international payments through mobile app. Ripple, the founder and developer of the blockchain-based Ripple payment system and exchange network, offered the technology for the solution.
Blockchain in digital identification

When online identity is moved to a blockchain-enabled infrastructure, users can choose how they identify themselves and with whom their identity is shared.
Users must still register their identities on a blockchain, but once they have done so, they do not need to do so again for each service provider, as long as those providers are likewise connected to the blockchain. For example, a digital single source of identifying information could enable more frictionless account opening, reduced resources and expenses, while ensuring data privacy. A number of startups are creating applications in the area of identity management.
Companies Developing Blockchain Services
There are companies in the US that have been associated with blockchain services for quite some time now. Moogle Labs, S-Pro, OpenXCell, etc.
Final Words
Blockchain service providers estimate that blockchain will gain more popularity in the near future because of its uses in digital identification, healthcare, and banking.
