Basic Concepts of Bitcoin Explained by Hong Jin Kyung

Understanding Bitcoin

Bitcoin as a digital currency

Bitcoin is a form of digital currency that can be stored on a smartphone or computer. It is not physical money like cash or credit cards but exists only in digital form. This means that you can save it on your device and use it for online transactions. Bitcoin was created to provide a decentralized and secure method of making online payments.

Bitcoin’s value

The value of Bitcoin has seen significant fluctuations since its inception. Initially, it was worth around 2,000 won but has now increased to around 20 million won. At one point, the price even rose to 80 million won for just one Bitcoin. The increase in value can be attributed to factors such as increased demand and the perception of Bitcoin as an investment rather than just a currency.

Acceptance as a form of payment

Although Bitcoin is not accepted everywhere as a form of payment, there are online stores where it can be used. In the past, Bitcoin was primarily used by hackers and people who wanted to hide their identity due to its anonymous nature. However, it has now expanded to regular cafes, restaurants, and general stores. Despite the increase in acceptance, there are still stores that do not accept Bitcoin as a payment method.

Bitcoin as an investment

Due to the fluctuations in Bitcoin’s price, it is now seen more as an investment rather than a traditional currency. People who buy Bitcoin are more likely to hold onto it in the hopes that its value will increase over time. This perception of Bitcoin as an investment has led to a decrease in its use as a currency for daily transactions.

Limited supply of 21 million coins

One unique aspect of Bitcoin is its limited supply. There will only ever be 21 million Bitcoins in existence. This is different from traditional currencies that can be printed by central banks. The limited supply of Bitcoin adds to its value and scarcity. It also means that once all the 21 million coins have been mined, no new Bitcoins will be created.

Blockchain Technology

Counterfeit detection and transaction security

Blockchain technology is the backbone of Bitcoin and other cryptocurrencies. It serves as a digital ledger that records all transactions made with Bitcoin. One of the main advantages of blockchain technology is its ability to catch counterfeit digital currency. The decentralized nature of the blockchain ensures that each transaction is verified and recorded, making it extremely difficult to counterfeit or manipulate.

Creation during a global financial crisis

Bitcoin was created in 2008 during a global financial crisis. Its creation was inspired by the need for a currency that did not rely on traditional banks and financial institutions. Bitcoin provided an alternative decentralized method of conducting transactions and storing value, independent of the traditional financial system.

Decentralized management of blacklists

In traditional financial systems, blacklists of counterfeit currency are managed by centralized entities, such as banks. However, with blockchain technology, the management of blacklists becomes decentralized. This means that users with blockchain programs installed can vote on and verify the validity of each transaction, ensuring the security and integrity of the system.

Examples of decentralized electronic currencies

Bitcoin and Ethereum are two popular examples of decentralized electronic currencies that use blockchain technology. These cryptocurrencies operate independently of central banks and are not controlled by any single entity. Their value and security are derived from the decentralized network of computers that participate in verifying and recording transactions on the blockchain.

Blockchain programs and voting on blacklists

Blockchain programs allow users to participate in the management of blacklists. Every ten minutes, users with blockchain programs installed can vote on the validity of transactions and verify the accuracy of the information recorded on the blockchain. This process ensures transparency and security within the system, as it relies on the consensus of multiple participants.

The Process of Mining

Explanation of mining

Mining is the process by which new Bitcoins are created and added to the blockchain. It involves using high-performance computers to solve complex mathematical problems. Miners compete against each other to find a solution and are rewarded with new Bitcoins for their efforts. This process is essential for maintaining the integrity and security of the blockchain.

Rewards for accurate and fast miners

In the mining process, miners who can solve the mathematical problems accurately and quickly have a better chance of being rewarded with new Bitcoins. This incentivizes miners to invest in high-performance computers and dedicate their resources to the mining process. The rewards for mining serve as a way to compensate miners for their computational power and ensure the continued operation of the Bitcoin network.

Electricity usage and high-performance computers

Mining requires a significant amount of electricity due to the computational power needed to solve the mathematical problems. Miners often set up specialized mining rigs, which are high-performance computers designed specifically for mining purposes. The electricity usage associated with mining has raised concerns about the environmental impact of cryptocurrency mining.

Bitcoin and Ethereum

Transparency and investment perception

Bitcoin and Ethereum are viewed as types of investments rather than scams due to increased transparency. The blockchain technology underlying these cryptocurrencies provides a transparent record of all transactions, which can be verified by anyone. This transparency has contributed to the perception of Bitcoin and Ethereum as legitimate investment assets.

Geopolitical factors and international recognition

Unlike traditional currencies, Bitcoin and Ethereum are not affected by geopolitical factors such as government policies or exchange rates. This gives them the advantage of being recognized internationally. Bitcoin, in particular, has gained recognition as a global currency that transcends traditional borders.

The Future of Bitcoin

Relying on user demand

The future of Bitcoin hinges on user demand and adoption. As more people recognize and accept cryptocurrencies, the demand for Bitcoin is likely to increase. However, the future also depends on factors such as government regulations and the development of alternative cryptocurrencies.

Desire for anonymity and increased value

The desire for anonymity and the opportunity for increased value are driving factors for the future of Bitcoin. Many individuals are attracted to the anonymity that Bitcoin provides, as it enables them to make transactions without revealing their identities. Additionally, the limited supply of Bitcoin and the potential for its value to increase make it an attractive investment option for some.
