What is Cryptocurrency?

On 31 October 2008, a link to a paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System was posted to a cryptography mailing list. Nakamoto implemented the Bitcoin software as open-source code and released it in January 2009. This marked the birth of Bitcoin, the first cryptocurrency, and opened up a new frontier in the world of finance and beyond.

 1. The Birth of Cryptocurrency

The birth of Bitcoin was a revolutionary moment in the financial world. It introduced a new type of currency, one that was digital and independent of any central authority. Bitcoin was created as a response to the financial crisis of 2008, with the aim of providing a more secure, private, and efficient way of transferring money.

2. What is Cryptocurrency?

A cryptocurrency is a digital or virtual currency that uses cryptography for security. This makes it nearly impossible to counterfeit or double-spend. Most cryptocurrencies exist on decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.

3. Understanding Cryptography 

Cryptography is the practice and study of techniques for secure communication in the presence of third parties. In the context of cryptocurrencies, cryptography is used to secure transactions and control the creation of new coins. Two important aspects of cryptography used in cryptocurrencies are private keys and seed phrases.

1. Private Keys

A private key is a sophisticated form of cryptography that allows a user to access their cryptocurrency. A private key is an integral aspect of Bitcoin and altcoins, and its security makeup helps to protect a user from theft and unauthorized access to funds.

1. Seed Phrase

On the other hand, a seed phrase, seed recovery phrase, or backup seed phrase is a list of words that store all the information needed to recover a Bitcoin wallet. A wallet typically generates a seed phrase and instructs the user to write it down on paper.

If the user's computer breaks or their hard drive becomes corrupted, they can download the same wallet software again and use the paper backup to regain their Bitcoins.

 4. How Does Cryptocurrency Work?

Cryptocurrency operates similarly to bank credit on a debit card. In both scenarios, a complex system issues currency and records transactions and balances, enabling people to send and receive currency electronically. Just as with banking, online platforms can be used to manage accounts and move balances. The primary difference between cryptocurrency and bank credit is that an algorithm issues the currency and maintains the ledgers, not banks or governments.

To explain the concept of cryptocurrency in detail, it's important to highlight its digital nature, peer-to-peer transfer system, use of blockchain technology, encryption, decentralization, and distribution across multiple computers. Additionally, cryptocurrencies are traded on online exchanges, much like stocks.

Klever Wallet, for example, provides its users with a Swap feature, where they can exchange crypto with ease inside Klever Wallet, with lower fees and fast speed. 

5. How do Crypto Transactions Work?

Transactions in the cryptocurrency world are sent between peers using software called “crypto wallets.” 

• The user creating the transaction uses the wallet to transfer balances from one account (a public address) to another.

•  A password, also known as a private key associated with the account is needed to transfer funds. 

• Transactions made between peers are encrypted and then broadcast to the cryptocurrency’s network and queued up to be added to the public ledger.

• Every participant in a specific cryptocurrency network can access its ledger if they wish. 

• The transaction amounts are publicly visible, but the sender's identity is encrypted, offering a degree of pseudo-anonymity. 

• Each transaction can be traced back to a unique set of keys, which signifies ownership of the corresponding cryptocurrency amount. 

• Each transaction is associated with a unique transaction hash. This hash, a cryptographic code generated by the transaction data, serves as a unique identifier, ensuring the integrity and security of the transaction on the blockchain.

• Many transactions are added to a ledger at once. These “blocks” of transactions are added sequentially by miners or validators. That is why the ledger and its technology are called  “Blockchain.” It is a “chain” of “blocks” of transactions.

6. Validating a Cryptocurrency Transaction

As for mining, cryptocurrencies use different consensus mechanisms to validate transactions and add them to the blockchain. The two most common are Proof of Work (PoW) and Proof of Stake (PoS).

Proof of Work is the mechanism Bitcoin uses and involves miners solving complex mathematical problems to validate transactions and add them to the blockchain. This process requires a significant amount of computational power and energy.

Proof of Stake, conversely, involves validators who hold and lock up some of their coins as a 'stake' in the system. The chances of a validator being chosen to validate a transaction depend on the number of coins they hold and are willing to 'stake'. This mechanism is less energy-intensive than Proof of Work.

KleverChain, for instance, uses Delegated Proof of Stake (DPoS), a variation of the PoS model, where coin holders vote for a few delegates that will secure the network on their behalf. This model aims to be more democratic and efficient than the traditional PoS and PoW models.

It's important to note that the choice of consensus mechanism has implications for the network's security, decentralization, and scalability.

7. The Impact and Future of Cryptocurrency

Cryptocurrency's global impact is profound, reshaping industries and redefining 'currency.' Its potential to disrupt traditional finance, democratize financial systems, and create new business models is immense. Despite differing views, the influence of cryptocurrencies is expected to be significant and long lasting.
