The term “Blockchain” has been coined to represent a new approach to thinking about the financial system and the Internet. According to its founders Blockchain “will connect people worldwide by utilizing real-time, digital currencies.” The Blockchains system has two layers that are private and public. The protocol lets users transfer, receive and store money, as well as record transactions and join the global money network. Blockchains can be used to keep their data in a ledger which tracks both the public and private keys that are associated to an account. This allows users to track their balances online and manage their finances without having to be a computer expert.
The reason some refer to Blockchains “digital golds” is due to the fact that it is like the gold standard, in that it can help keep track of the gold that has been bought. The ledger utilizes digital gold instead of physical gold. The ledger lets users create transactions and edit them instantly, all from their desktops, laptops, or smartphones. Transactions can occur within the same network or across multiple networks. A ledger enables transactions to be made and received without the need for third parties or banks. This is why most businesses make use of it.
Another major characteristic of the Blockchain is its decentralized structure. The ledger permits blocks to be linked together through specific computers, however the entire system is made of thousands of ledgers that are distributed across the world. The ledger has very low fees for transactions and also has very little downtime. Its decentralized nature is what allows it to manage large quantities of transactions and also provide excellent security. If one computer is damaged, then that’s it. No other computer in the system will be able to perform the required transactions.
One of the major advantages of the Blockchain is the use of hash chains. A hash chain is simply an accumulation of various transactions happening in chronological order. The transactions take place among nodes of the ledger at the most basic level. Nodes are independent computers that communicate with each other through a peer-to-peer networking protocol. Transactions occur through the simple confirmation that each computer sends to others, and then the transaction is added to the chain.
The Blockchain makes use of a distributed ledger instead of an centralized one. This allows multiple chains to operate simultaneously. Here’s how it works. The transaction happens when an output is generated by the node to which the transaction is being sent. The second block is then generated, which contains the proof-of work for that transaction.
After two chains have been created the transactions are recorded and added to the ledger. The third block, also known as a chained together block, is created at this moment. It adds to the previous two. The entire ledger is updated once the final block is created. The Blockchain is, in essence, a method of securing the entire ledger, ensuring that only valid transactions can been recorded and verified.
It’s fascinating to observe how the Blockchain works. Imagine how the entire world is connected through networks of computers. These computers act like banks, cooperating with each other and processing transactions on a broad scale. Since the computers aren’t tied to any specific location, the ledger is decentralized and all the computers operate in sync. That’s the beauty behind the Blockchain as each transaction is processed within the entire system in a manner that is extremely resistant to hacking.
This brings up a very good question: how do cryptosporters secure the confidentiality of their transactions? Central authority. By ensuring that every transaction is processed on each individual computer, no-one is able to alter the ledger or take any transactions from the ledger. It also requires collaboration between several computers, so it’s impossible for a hacker to infiltrate and attack the system, weakening the cryptography used.
