The blockchain is the world's leading software platform for digital assets. This blockchain platform offers the largest production in the world, using new technology to build a radically better financial system. The blockchain is technologically advanced wide-reaching system that will not only revitalize financial services, but also other businesses and industries. This storage device is a financial database that stores a constantly growing list of ordered records, called blocks. Each block has a timestamp and a link to a previous block, successfully maintaining the transaction history of every user in one concrete database. This concept was first introduced in 2008, and then quickly released to the public in 2009 as part of the digital Bitcoin currency. It serves as the public ledger for all Bitcoin dealings. Using this blockchain system, Bitcoin was able to became the first digital currency to solve the double spending problem. So, what makes blockchain so secure? The security system is built into the blockchain through a distributed time stamping server and a peer-to-peer network. Consequently, the database has also become autonomous through a decentralized system. This makes block chains excellent for recording events, such as medical records — transactions, proving provenance and identity management. It is essentially offering the potential of mass disintermediation of trade and contract processing. Blockchain technology allows someone to send currency anywhere in the world to someone who has access to the blockchain file. However, a person must have the private, cryptographically-created key to access the blocks an individual owns. By implementing this strategy, the system establishes trust and identity. The only downside is that no one can edit a blockchain without having the conforming keys. Without the keys, unverified edits can be rejected. Also, while there is the possibility of the keys being stolen, new code can be generated to keep someone's information kept secure with little expense. In other words, major fraud prevention functions normally carried out by banks can be carried out by blockchains more quickly and efficiently. When it comes to transferring value or money, we are usually forced to fall back on old fashioned, central financial establishments, such as banks. In fact, the online payment method which came into existence since the birth of the internet, generally required the integration of a bank account or credit card. It is predicted that by 2025, 10 % of the global GDP will be stored on blockchains or blockchain-related technology, meaning that this is an innovation people should get acquianted with now. However, without taking the time to learn all the benefits and aspects of blockchains, decreases the rate of influence in the global economy. Blockchains can be used to store any type of digital information, including computer code. While this code is programmed to assist multiple users, a contract has to be agreed upon to ensure to efficient transaction. Besides that, the external data feeds like stock prices, weather reports, and news headlines can be analyzed by computer code, which, in turn, helps to create contracts automatically “signs off” when stated conditions are filled. These are known as “smart contracts”. With so many safeguards and added features, this technology has nearly limitless potential.
