Blockchain and how it is useful in digital currency

The blockchain is essentially a digital ledger, or list of transactions. In a public blockchain, anyone on the internet can read what’s on it and can verify for themselves that these transactions are true. The best known example is Bitcoin, but numerous other public blockchains have been created in the last couple of years.

In a private blockchain, the participants are known and trusted: these transactions are visible only to those who are “members” in this virtual club.

Bitcoin, the first cryptocurrency to gain popularity, is currently worth around $43,000 per coin. That price has been steadily climbing over the last year, and the total value of all Bitcoin in circulation is now just north of $1.03 trillion.

The rise in value of cryptocurrencies has led many people to wonder if their own businesses should start accepting digital currencies in addition to or in place of traditional currencies. Some have argued that the market will see a correction, others that adoption is inevitable.

Another application for blockchain technology is voting, where the same cryptographic technology can be used to verify voting records. In essence, blockchain technology is a way of creating transparent and secure voting records that cannot be manipulated.

The technology could also reduce instances of voter fraud by making it harder to commit voter fraud and ensuring that votes cannot be changed after they have been cast. It can also improve elections by providing voters with even more information on candidates and their positions through on-platform updates via news feeds.

With this technology, every participating computer receives a copy of the blockchain and processes transactions in real time, so there is no opportunity for one party to use its resources to gain an unfair advantage.

Automated processing and lower fees could also reduce costs in a number of other ways. For example, smart contracts can be used to program payments to automatically go through when certain conditions are met – such as when a shipment arrives at its destination, or a service is completed. This can eliminate the need for costly third-party intermediaries, which both saves money and reduces the potential for error.

Business owners are often mulling over how to take advantage of the blockchain and its potential to change the way their business operates. But potential blockchain applications for business go far beyond those that have been widely discussed in the media.

Once a block is created, miners work to solve a difficult mathematical problem, one that requires an immense amount of computer processing power. Once solved, the verified transaction is added to the blockchain and the miners move on to the next set of transactions (hence the term “blockchain”). As each block enters the system, it must be accepted by the rest of the network.
