Cryptocurrencies appearance today

Postby Vuk В» 07.01.2020


Today cryptocurrencies Buy Crypto have become a global phenomenon known to most people. In this guide, we are going to tell you all that you need to know about cryptocurrencies and the sheer that they can bring into the global economic system. Take our blockchain courses to learn more about the blockchain. But beyond the noise and the press releases the overwhelming majority of people — even bankers, consultants, scientists, and developers — have very limited knowledge about cryptocurrencies.

They often fail to even understand the basic concepts. Few people know, but cryptocurrencies emerged as a side product of another invention. Satoshi Nakamoto, the unknown inventor of Bitcoin , the first and still most important cryptocurrency, never intended to invent a currency. His goal was to invent something; many people failed to create before digital cash. Announcing the first release of Bitcoin, a new electronic cash system that uses a peer-to-peer network to prevent double-spending.

In the nineties, there have been many attempts to create digital money, but they all failed. After seeing all the centralized attempts fail, Satoshi tried to build a digital cash system without a central entity. Like a Peer-to-Peer network for file sharing. This decision became the birth of cryptocurrency.

They are the missing piece Satoshi found to realize digital cash. To realize digital cash you need a payment network with accounts, balances, and transaction. One major problem every payment network has to solve is to prevent the so-called double spending : to prevent that one entity spends the same amount twice. Usually, this is done by a central server who keeps record about the balances. So you need every single entity of the network to do this job.

Every peer in the network needs to have a list with all transactions to check if future transactions are valid or an attempt to double spend. But how can these entities keep a consensus about these records? If the peers of the network disagree about only one single, minor balance, everything is broken.

They need an absolute consensus. Usually, you take, again, a central authority to declare the correct state of balances. But how can you achieve consensus without a central authority? Nobody did know until Satoshi emerged out of nowhere. In fact, nobody believed it was even possible.

Satoshi proved it was. His major innovation was to achieve consensus without a central authority. Cryptocurrencies are a part of this solution — the part that made the solution thrilling, fascinating and helped it to roll over the world. If you take away all the noise around cryptocurrencies and reduce it to a simple definition, you find it to be just limited entries in a database no one can change without fulfilling specific conditions.

This may seem ordinary, but, believe it or not: this is exactly how you can define a currency. Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes?

Money is all about a verified entry in some kind of database of accounts, balances, and transactions. So, to give a proper definition — Cryptocurrency is an internet-based medium of exchange which uses cryptographical functions to conduct financial transactions. Cryptocurrencies leverage blockchain technology to gain decentralization, transparency, and immutability. A cryptocurrency like Bitcoin consists of a network of peers. Every peer has a record of the complete history of all transactions and thus of the balance of every account.

After signed, a transaction is broadcasted in the network, sent from one peer to every other peer. This is basic p2p-technology. The transaction is known almost immediately by the whole network. But only after a specific amount of time it gets confirmed. Confirmation is a critical concept in cryptocurrencies. You could say that cryptocurrencies are all about confirmation. As long as a transaction is unconfirmed, it is pending and can be forged. When a transaction is confirmed, it is set in stone.

Only miners can confirm transactions. This is their job in a cryptocurrency-network. They take transactions, stamp them as legit and spread them in the network. After a transaction is confirmed by a miner, every node has to add it to its database. It has become part of the blockchain. For this job, the miners get rewarded with a token of the cryptocurrency, for example with Bitcoins.

Principally everybody can be a miner. Since a decentralized network has no authority to delegate this task, a cryptocurrency needs some kind of mechanism to prevent one ruling party from abusing it. Imagine someone creates thousands of peers and spreads forged transactions. The system would break immediately. So, Satoshi set the rule that the miners need to invest some work of their computers to qualify for this task. In fact, they have to find a hash — a product of a cryptographic function — that connects the new block with its predecessor.

This is called the Proof-of-Work. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins. This is part of the consensus no peer in the network can break. If you really think about it, Bitcoin, as a decentralized network of peers that keep a consensus about accounts and balances, is more a currency than the numbers you see in your bank account.

Basically, cryptocurrencies are entries about token in decentralized consensus-databases. Cryptocurrencies are built on cryptography. They are not secured by people or by trust, but by math. It is more probable that an asteroid falls on your house than that a bitcoin address is compromised. Describing the properties of cryptocurrencies we need to separate between transactional and monetary properties. While most cryptocurrencies share a common set of properties, they are not carved in stone.

By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. If you send money, you send it. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters.

While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real-world identity of users with those addresses. Since they happen in a global network of computers they are completely indifferent of your physical location. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers make it impossible to break this scheme.

A Bitcoin address is more secure than Fort Knox. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper. In Bitcoin, the supply decreases in time and will reach its final number sometime around the year All cryptocurrencies control the supply of the token by a schedule written in the code.

This means the monetary supply of a cryptocurrency in every given moment in the future can roughly be calculated today. There is no surprise. To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible, and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens.

As money with a limited, controlled supply that is not changeable by a government, a bank or any other central institution, cryptocurrencies attack the scope of the monetary policy. They take away the control central banks take on inflation or deflation by manipulating the monetary supply.

Sometimes it feels more like religion than technology. Cryptocurrencies are digital gold. Sound money that is secure from political influence. Money promises to preserve and increase its value over time. Cryptocurrencies are also a fast and comfortable means of payment with a worldwide scope, and they are private and anonymous enough to serve as a means of payment for black markets and any other outlawed economic activity.

But while cryptocurrencies are more used for payment, its use as a means of speculation and a store of value dwarfs the payment aspects.
