What we mean by decentralized is that there is no central authority like banks or the government to regulate this type of currency. This decentralization and the method of encrypting transactions make it nearly impossible to counterfeit or manipulate cryptocurrencies. As we know many companies issue their own currencies which can then be used to trade specifically the goods and services that the company provides, for example, all our money, Zometa wallet, or even casino chips. The difference between these token currencies and cryptocurrencies is precisely what we talked about earlier, decentralization and secure transactions.
In fact, crypto in cryptocurrency refers to the cryptographic techniques and encryption algorithms that it uses. Along with that, to manage and record transactions. Most cryptocurrencies use a technology called blockchain, which keeps an online ledger of all the transactions that have ever been conducted and spreads them out across various computers. Bitcoin was the first blockchain-based cryptocurrency and it still remains the most valuable and popular. Let's look at this record-keeping technology behind bitcoin. Blockchain is basically a specific type of database. What is a database is a collection of information is stored electronically on a computer system.
Typically, information or database are structured in a table format, to allow easier search and filter options, kind of like a spreadsheet, but bigger, faster, and accessible by any number of users at once. So how does a blockchain differ from a database? Well, all blockchains are databases. But not all databases are blockchains. The key difference lies in the way the data is structured. A blockchain collects information together in groups that are known as blocks. These blocks have a certain storage capacity and when full, are chained onto the previously filled block, forming a chain of blocks containing data. Hence the name blockchain. Any new information is now added to a fresh block which will again be added to the chain. Once filled. Each block is given an exact timestamp as to when it is added to the chain.
This system results in an irreversible timeline of data if implemented in a decentralized way. And in bitcoins case, as we know blockchains lasers are spread across various computers, so no single person or group has control. Instead, all users store data collectively. So each computer or a group of computers is operated by separate individuals or groups in a different geographical location. These computers that make up the bitcoins network are called nodes. And in blockchain, each node has a full record of the data stored on the blockchains. Since its inception, in the case of Bitcoin, the entire history of Bitcoin transactions.
So if one node has an error in its data, it can use the 1000s of other nodes as a reference point to correct itself. This way, no one node within the network can alter data, again, making the history of transactions in each blockchain irreversible, it makes the system transparent.
Let's say you want to hack and alter the blockchain. To steal Bitcoins. If you just change your copy, it will just be rejected by the other nodes as illegitimate to actually pull off a feed like that you will have to control and chain at least 30% of all the nodes at the same time and attacks so use will cost more than it can steal, making it practically fruitless. This technology that makes it impossible to forge transactions is central to the appeal of Bitcoin or other cryptocurrencies.
