“Blockchain” was developed to represent a new approach to the Internet and financial system. The system, according to its creators “will connect people across the globe by using real-time digital currencies”. There are two layers to the Blockchains system; the public and the private. The protocol enables users to send or receive, keep track of and be part of the worldwide financial network. Blockchains will let people store data on a ledger which tracks both the public and private keys associated with an account. This allows users to keep track of their balances online and manage their money without the need for a computer expert.
The reason some refer to Blockchains “digital golds” is due to the fact that it is similar to the gold standard, in that it helps identify the gold that was purchased. This ledger, however, makes use of digital gold rather than physical. The ledger allows users to add transactions to and edit them instantly, all done at the convenience of their desktops, laptops or even smartphones. Transactions can be made within the same network or across multiple networks. A ledger enables transactions to be completed and received without the need for third parties or banks. This is why the majority of businesses use it.
Another major aspect of the Blockchain is its decentralized structure. The ledger allows blocks to be connected together through specific computers, however the entire system is composed of thousands of individual ledgers distributed around the world. The ledger is extremely low in transaction fees and downtime. The decentralization aspect of the system is what gives it the ability to handle a large volume of transactions while providing excellent security at the same time. If one computer is damaged, then it’s over; no other computer on the system can complete the necessary transactions.
The usage of a hash chains is one of the key characteristics of the Blockchain. A hash chain is simply an array of transactions happening in chronological order. The transactions occur between nodes in the ledger at the most basic level. Nodes are computers that are connected to each other through a peer-to–peer networking protocol. Transactions take place through the simple confirmation that each computer transmits to the others, and then the transaction is added to the chain.
The Blockchain makes use of an open ledger, rather than a central one. This allows multiple chains to be in existence simultaneously. If you’re wondering about how it all works, here’s the explanation. When a transaction occurs an output is created by the node that the transaction is to be sent to. A second block is then generated, containing the proof-of-work for the particular transaction.
Once two chains are created, transactions take place and are added to your ledger. The third block, also known as a chained-together block, is created at this stage. It is added to the previous two. The entire ledger is updated when the final block has been created. The Blockchain is, in essence, a way to secure the entire ledger to ensure that only valid transactions can been recorded and verified.
It is fascinating to look at how the Blockchain works. Imagine that the whole planet is interconnected by computers’ networks. They function as banks by working in concert with one another and processing large-scale transactions. But because the computers aren’t tied to a specific location, the ledger is decentralized and all the computers act in concert. This is the appeal of the Blockchain every transaction is handled by the entire system in a way that is highly secure from hacking.
This raises a important question: how can cryptosporters secure the confidentiality of their transactions? A central authority. By ensuring that every transaction is handled on each individual computer, no one is able to alter the ledger or take any transactions from the ledger. It also requires the collaboration of multiple computers, which means it’s impossible for hackers to penetrate and compromise the system, thereby weakening the cryptography used.
