“Blockchain” was created to represent a fresh way of looking at the Internet and financial system. According to its founders “will connect people around the world by using real-time digital currencies”. There are two layers in the Blockchains system: the public and the private. The protocol allows users to send and receive, as well as store, record, and participate in the worldwide financial network. Blockchains are a way to store, transfer, and record money. Blockchains can be used to keep their data in a ledger which tracks both private and public keys associated with a specific account. This allows users to keep track of the balances of their accounts and track their money over the internet without the need to be a computer expert.
Blockchains are often referred to as “digital golds” because they track gold purchased. The difference though is that this ledger, instead of using physical gold, utilizes digital gold. The ledger lets users add transactions and modify them in a matter of minutes, all via their desktops, laptops, or even mobile phones. Transactions can be done within the same network, or across multiple networks. A ledger allows for transactions to be recorded and received with no need of banks or third parties. This is the reason why a majority of businesses use it.
The Blockchain’s decentralized design is another important aspect. The ledger permits blocks to be connected together through specific computers, however the entire system is composed up of thousands of individual ledgers that are distributed across the world. The ledger is extremely low in transaction costs and downtime. The decentralized aspect of the system is what gives it the ability to handle a large volume of transactions, while also providing high security at the same time. If one computer crashes the system will shut down and the other computers will be able to handle the necessary transactions.
One of the most important features of the Blockchain is the use of hash chains. A hash chain is simply referring to a set of transactions that occur in chronological order. The transactions take place among nodes of the ledger at the most fundamental level. Nodes are computer systems that are connected to one another via a peer-to–peer networking protocol. Transactions happen as a result of the simple confirmation that each computer sends to the other computers, and then the transaction is added to the chain.
The Blockchain utilizes an open ledger, rather than a central one. This allows multiple chains to be in existence simultaneously. Here’s how it works. The transaction occurs when an output is generated by the node to which the transaction is being sent. A second block is then created, which contains the proof-of work for the transaction.
After two chains are created the transactions are recorded and recorded in the ledger. At this point, the third, or chained together block is made, adding to the two blocks before it. After the last block is made, it’s the entire ledger that’s being updated. The Blockchain is, in essence, is a way to secure the entire ledger to ensure that only valid transactions are recorded and verified.
The way the Blockchain operates is truly intriguing. Imagine how the entire world is connected through networks of computers. These computers serve as banks by coordinating with each other and processing large-scale transactions. However, since they aren’t tied to a specific location the ledger is distributed and all computers work in concert. The benefit of Blockchain is that each transaction is processed by the entire system in a manner that is extremely resistant to hacking.
This raises a great question: How can cryptosporters protect their transactions? A central authority. By ensuring that every transaction is processed on every individual computer, nobody can change the ledger and eliminate any transaction from the ledger. It also requires collaboration between several computers, so it is impossible for hackers to gain access and hack into the system, thereby weakening the security of the cryptography used.
