(Newswire.net — July 15, 2020) — Decentralized virtual currency is built on the basic technology called block chain. This is a mechanism that prevents double use of coins that are electronic data, so if used correctly, safety can be expressed. Although there are technical issues with block chain, improvements are steadily progressing.
Bitcoin and Ethereum, which can be said to be the precursors of decentralized virtual currencies, are not managed by operators but run by a code program called block chain. It is designed so that it works correctly even if there is no operator in the center, and the value expressed as a coin cannot be used twice, and only the person who has the private key can move the coin. The Bitcoin Code is best software for bitcoin trading.

Furthermore, what is important for safely handling virtual currencies is a technology called multi-signature multi-sig, in which value cannot be transferred unless you have two or more keys. To use Bitcoin, put wallet software Wallet in your smartphone, but only the private key is in it. The unused UTXO balance is recorded by computers called nodes that are distributed all over the world. There are about 11,000 nodes in the world, sharing all transaction records. On the other hand, the value of the coin can be transferred if you get the private key, so you will be the target of the attack. Since it is very difficult to protect a machine in a general environment from a professional cyber attack, the use of multi sig has advanced.
Until a certain time, when you opened an account on a virtual currency exchange, it set up a web wallet and displayed the address of Bitcoin and the transaction history held here. This allows users to check whether the transactions they have made are correct, and multi sig ensures the security of private keys that cannot be protected by them having professional involvement. He was able to do it.
However, recently, instead of using multi sig to give users bitcoin addresses, exchanges tend to set up accounts for customers collectively and operate it as exchange account transactions. While efficient for exchanges, users will not be able to see the transactions they have requested on the block chain corresponding to their private key.
Block chain is a natural audit system
Even if the audit firm does not investigate anything afterwards, the audit ends when the transaction is made on the block chain. The multi sig mentioned here is an example of block chain technology, but there are other proposals to improve security. It can be said that the tragedy mentioned above is caused by the fact that the superiority should be utilized most and not utilized.
It is said that by building an economic and social platform that utilizes block chain, an autonomous smart economy that minimizes human involvement will be realized. This is called the block chain economy. The block chain economy consists of a three-layer structure, a payment service, a block chain platform that provides services, and a legal system enforcement system.
The public decentralized crypto currency block chain is designed so that once it’s started, no one can change it. It’s an engine or a chronicle that operates according to the rules without human intervention, so you think it is right to handle the payment service part as it is.
It is expected that the block chain-based service provision platform on top of that will not exist independently of the first-tier payment services, but will spread as an integral part. This is because even if there are no referees in the middle, that is, people who do not know who they are carry out economic activities according to their contracts.
A virtual currency that became a hot topic in the fraudulent out flow problem in the first half of the year. There are multiple types such as Bitcoin, Ethereum and Ripple, and the distribution volume is basically increasing. In 2017, the word billionaire was born, which earned a huge amount of wealth through virtual currency investment. On the other hand, there are many people who are worried about the unfamiliar virtual currency. What is virtual currency for, and how will it affect your lives?
