Comparator decentralized currency

1. bitcoin is valuable under certain circumstances, but it is worthless under certain circumstances. Because it's not legal tender. It is impossible for any country to get the right to issue legal tender to use any mining machine. Bitcoin is just a virtual number. While it's still possible to change money, change it quickly! It's too late to wait until it's worthless at the end.

2. Because bitcoin does not exist in the issuing institutions (bitcoin is extracted from the network), nor does it exist in banks, but directly through a personal to personal transfer.

3. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.

4. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

Many people think that the reason why bitcoin is valuable is because it is "rare", and if bitcoin is no longer "rare", then it will not have value

this is a misunderstanding. Let's consider a question: what is the essence of all "currencies"

the answer is trust. The biggest reason for the value of the dollar is because of the credibility established for the dollar under the Bretton Woods Agreement, rather than the so-called equivalent exchange with gold (although others say so). The main reason why RMB is valuable is because of the trust system of RMB in China and neighboring countries, rather than the exchange with us dollar reserves (see offshore RMB). This can explain why the currencies of some countries (such as the ruble of Russia, as well as the Zimbabwean currency as you all know) have been greatly devalued, because the government and the current world situation have led to a trust system that does not support the existence of this currency. The so-called economic sanctions and currency speculation are very superficial and superficial reasons

the essence of money is trust

What about bitcoin

bitcoin has no centralized Trust Measurement institution. The value of bitcoin, namely its "credit system", comes from distrust of centralized units. Every country finds that seigniorage is too easy to collect, which leads to the increasingly poor trust between countries. Even the people of all countries do not trust the national currency

and trust, like quality, is conserved. Trust in centralized money decreases, while trust in decentralized money increases naturally

this is the essential reason why the value of bitcoin continues to rise. Therefore, for digital currencies such as bitcoin, there are only two outcomes. Either countries want to understand that they will no longer issue excess currencies, issue additional currencies in a scientific and reasonable way, unify stable exchange rates, and maintain the credit system of centralized currencies, then the value of bitcoin will be infinitely close to zero. Or countries will continue to drink water to quench their thirst, and more frantically use the method of issuing excess currency to collect seigniorage from everyone, then the trust in the centralized currency will be lower and lower, and the total value of bitcoin, a decentralized currency, will be infinitely close to the gross labor value of all the units that do not trust the government and other governments, but need international trade

either the price is crazy or it's worthless

after understanding these, we can answer this question. Will bitcoin be replaced by other digital currencies

swindlers like * * and even the old Wang next door can come and yell, "I spent 10 minutes to change bitcoin's core and create a new digital currency called SBC. Come and join my ICO and pay me seigniorage ~". So, if this happens, will you immediately choose to use Lao Wang's SBC next door

the answer is that some speculators will participate, but the market will not. The reason is very simple, the new cryptocurrency has not been recognized by the market, the application has not been proced, this kind of currency has no way to exchange for means of proction. Then this kind of currency is not money, but a virtual commodity for speculation. In other words, even if old Wang ICO next door has an SBC, no one will choose this kind of currency except those speculators who have no brains

in the current market, there are many other digital currencies, such as Ethereum, EOS, XRP, and so on, which may have technological advantages in some aspects (in fact, BTC has been evolving, and it will also learn from the advanced technologies of other digital currencies that have been successfully proved by the market. LTC and other currencies can be said to be the experimental currencies of BTC's advanced technologies.), There may be more application scenarios than BTC in the future, but they are not likely to challenge the status of BTC. BTC will always be the first consensus in the currency circle, which is the belief of many people. BTC will exist for a long time as the gold in the currency market, not mainly for the circulation of digital currency

6. The design of "decentralization" determines that the "centralized" government cannot touch bitcoin
the emergence, development, amendment, circulation and extinction of bitcoin do not depend on the government, so "whether the government allows" has nothing to do with "whether bitcoin exists"
for example, the birth, development and extinction of the solar system do not need the permission of the government
if bitcoin is exchanged with the government controlled "legal tender" (such as US dollar), the government can influence the performance of bitcoin by controlling the legal tender
if the recognition of such assets reaches the bottom line of% 35 in 2019, the world pattern will be more reasonable, transparent and open

how should we deal with the coming risks- Buy bitcoin quickly to deal with the risk of "no bitcoin".

7. Litecoin is a kind of network currency based on "peer-to-peer" technology, which can help users pay to anyone in the world immediately. At present, lightcoin is the second virtual currency after bitcoin in global circulation market value. The legends of bitcoin, Wright silver, infinite copper and pennies aluminum (Internet) are popular in the circle. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Litecoin is inspired by bitcoin (BTC), and has the same implementation principle in technology. The creation and transfer of litecoin is based on an open source encryption protocol, which is not managed by any central authority. Litecoin aims to improve bitcoin. Compared with bitcoin, litecoin has three significant differences. First, the liteoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the output of litecoin network is expected to be 84 million litecoin, which is four times the amount of currency issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in litcoin's workload proof algorithm, which makes it easier to mine litcoin on ordinary computer than bitcoin. Each litecain is divided into 100000000 smaller units, defined by eight decimal places. Lightcoin needs to be generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoin at one time. At present, the computing power of lightcoin is growing rapidly, and miner can't dig mine through several computers. Therefore, it needs to be added to the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher. At present, the well-known ore pools abroad include: wemineltc, coinotron, etc

8. This is based on a specific code. A specific number of coins are limited, so many are made, many are printed, so the proportion of bitcoin is very unstable, and it is normal to rise or fall by thousands
mining is equivalent to using a mining machine (which looks like a computer host, but it's very difficult to kneel down for tens of thousands) to find it on the Internet according to calculation
what else do you don't understand

In bitcoin white paper "bitcoin: a peer-to-peer e-cash system", Nakamoto explained in detail how he designed the system. Among them, he established the main design principles of all blockchain systems since then

a real peer-to-peer e-cash should allow direct online payment from the originator to the other party without the need to go through a third-party financial institution

although the existing digital signature technology provides some solutions, if a trusted third party organization is needed to prevent "double payment", the main benefits (Brought by e-cash) will be lost

aiming at the problem of "double payment" in e-cash, we provide a solution with peer-to-peer network technology

in this network, transaction records are time stamped, hashed and merged into a growing chain, which is composed of hash based proof of work. If the proof of work is not redone, the resulting records cannot be changed

the longest chain is not only a proof of the observed sequence of events, but also a proof that it is generated by the largest pool of CPU processing power. As long as the computer nodes that control most CPU processing power do not join forces to attack the network itself, they will generate the longest chain and leave the attacker behind

the network itself only needs the simplest structure. Try your best to broadcast the information on the whole network. A node can leave and rejoin the network at any time. It only needs (when rejoining) to take the longest workload proof chain as the proof of the transaction occurred ring the node's offline period
