Lightcoin wallet public key private key
bitcoin is rising wildly, and e-money has set off a wave of speculation. Light currency (LTC) soared more than ten times, reaching a high price of 300 yuan. At the same time, a large number of counterfeit coins appeared, and the increase was amazing. It's not unusual to see them rise several times a day. E-money market has shown a strong speculative, investment risk has emerged. But is bitcoin the only winner? Is there any other e-coin that can "" the miracle of bitcoin, or even surpass it
assuming the success of e-money in the future, some people say that we only need one e-money. If the number of bitcoin is limited, it's OK to use mbtc or smaller units to trade when the price is very high. Other electronic coins are repetitive and meaningless
let's see how bitcoin has changed from "meaningless behavior" to a successful case, and what experience can be summed up
firstly, based on the combination of private key and public key of electronic cryptocurrency, bitcoin creatively proposed the block chain mechanism, as well as the binding of mining (protecting the whole network) and currency issuance rewards. And the implementation of a constant total to create deflation expectations, difficulty automatic adjustment to ensure fairness, as well as competitive mining and competitive block branches, to maximize the protection of the interests of the holders and miners, to achieve a win-win situation
this mechanism mobilizes the enthusiasm of miners and forms a virtuous circle. BTC rises, calculating power rises, calculating power rises, BTC is more stable and has higher value, so as to promote the price to continue to rise. Until now, bitcoin has formed an indestructible block chain system, which is the most valuable part of the bitcoin system, ensuring the maximum security of bitcoin holders, as well as the decentralized network structure, ensuring the openness and fairness of the bitcoin world. Social capital has invested a lot in bitcoin, forming a whole instrial chain. This is the value created by bitcoin from scratch. Although there are speculative factors, to a certain extent, the market value of bitcoin reflects this value
BTC market value: http://blockchain.info/charts/market-cap
BTC calculation force: http://blockchain.info/charts/hash-rate
but does this mean that bitcoin must be the most successful, and it will forever occupy the market share of the whole e-money in the future without further improvement
next, I'll make a comparison with LTC. Instead of recommending buying LTC, I'll talk about whether LTC can solve some problems of BTC and whether it will cause some new troubles< First of all, BTC has the following problems:
1, long confirmation time
I casually selected the current mining records and found that the block confirmation time was too long. First of all, the BTC default 10 minutes out of the block, has been a relatively long time. For some deals, it's a time of impatience. And because the difficulty is already very high, the block time is further uneven, sometimes it is normal not to block for 20 minutes. These 20 minutes, together with the confirmation waiting time and other processing time of various trading websites, often result in extremely slow recharge and withdrawal speed. It is common to wait for an hour. Waiting for a bitcoin transaction is really a boring thing, which limits its application in reality. Even for this reason, a third party, similar to Alipay's third party centralization letter, is needed to solve.
the two-and-a-half block time of LTC greatly alleviates this problem. An LTC transaction will be completed in a short time without any anxious waiting. It can be said that LTC solves the problem of BTC
2, centralization
although BTC claims to be a decentralized currency, it is relative to legal currency. In practice, e to historical problems and ASIC mining machine problems, BTC's centralization problem is very serious, which can be discussed from two aspects
the first is the centralization of computing power. Although ASIC mining machine is inevitable in history, BTC is rising rapidly, so the centralization of computing power is very serious. It can be seen from this picture that the first and second mines are ready to start 51%. Although it is said that 51% will destroy the whole network, which is not good for the mining pool, bitcoin is a place outside the law after all. Everything is guaranteed by mathematical formulas and algorithms, and credit is established voluntarily. In the face of huge profit temptation, it is inevitable that nothing will happen, or the confidence of the holders will be affected. This is not good for bitcoin
some people say that LTC will develop special mining machines sooner or later, so as to enter the era of centralization. I think there is a degree of problem. After all, it is a fact that bitcoin mines are seriously concentrated, and as long as the concentration of LTC is lower than BTC, the risk can be smaller
the second is the centralization of holding money. I don't have statistics of LTC holding currency here, but I have statistics of BTC holding currency. This centralization of holding money is appalling. This means that a very small number of people control the vast majority of the wealth of the entire network. Of course, some addresses belong to the exchange, but this is absolutely very serious differentiation. Here's the data: http://btc.ondn.net/search
and the centralization of computing power aggravates this situation: half of bitcoin has been g out and concentrated in the hands of a few people, and then the rest that has not been g out will also be g out by a few people (because of the concentration of computing power). The new people have no choice but to pay for it
although some people refute me that since BTC is valuable, it should be exchanged with legal currency. The problem is that when the existing BTC has been monopolized, the future BTC will also be monopolized, and the price is not set by the buyer. It's like everyone says that China's real estate is unfair. If the existing houses are controlled by a few "real estate uncle" people, The land development in the future is also tightly controlled by the Bureau of land and resources. Isn't it true that the common people have to pay for it, and how much they will pay for it is up to them
- the original attitude towards real estate changed when it came to BTC. Of course, the reason is that the bottom of the BTC holder determines the head. As if you bought a few suites, you will say that the real estate market is fair
by contrast, LTC has only g up a quarter of the total, and the computing power is relatively average. Any ordinary people can buy a graphics card to dig their own mines. At least the new LTC can be obtained at a relatively balanced price. From this point of view, if the overall value of e-money needs to be increased by 10 billion or even 100 billion US dollars in the future, then adding all of them to BTC will only lead to a few people becoming millionaires of 100 billion US dollars, which is obviously not the original intention of developing e-money< There is a serious problem with Nakamoto's BTC, which is that Nakamoto has more than 2 million BTCs. Now we are willing to believe that Nakamoto is a good man and a God, but how can we trust an indivial when we believe in mathematics and physics? On the premise of minimum trust, Nakamoto is also a mortal. If the market value of BTC is large enough, Nakamoto's goods will become a time bomb. Even if he doesn't drop the price, he becomes the God of the world and has the most wealth. Not to mention that some BTCs confiscated by the FBI will be auctioned sooner or later. This good thing that has contributed to the American people will be left to the people of the world
LTC does not have this problem. The history is very clean. We dig together and everything is open. When digging LTC, many players already have BTC experience, so the mining is relatively balanced at the beginning, and there is no private situation such as the founding team stealing. This has laid a good foundation for LTC.
4. Whether the gold silver ratio is applicable to BTC and LTC is a funny question, which just shows the ignorance of public speculators. Bitkin, Wright silver, said that this statement of the media is a manifestation of extreme ignorance
first of all, is the value of e-money related to the circulation? If the circulation of LTC is a quarter of that of BTC, is the value of LTC a quarter of that of BTC? If I issue a kind of NCC with brain damage now, with only one circulation, should the price be 9999999
it's just as ridiculous to anchor the issue volume as to compare the circulation of stocks. Money can only be valued by the total market value. It's meaningless to talk about circulation. As for the gold and silver ratio, it's a big laugh. The ratio of gold and silver is determined by the instrial value and output of gold and silver. Electronic money has no value other than monetary property, and there is no such thing as output and reserves. The output and reserves of money are only monetary units. If you don't understand this, you can go back to the furnace
moreover, BTC and LTC have direct exchange markets, and their proportion is the result of market game, which is the short-term optimal solution in itself. There is nothing to say. What the market says is what it says, which has nothing to do with the current market, let alone gold and silver
5. About Shanzhai coin
some people say that LTC is also a kind of "counterfeit" currency, which has no value. Some people think that with so many counterfeit coins, you can fry any one that is not. I think both views are wrong
first of all, BTC is an open-source e-coin, and the word "Shanzhai" itself contains a strong central idea in the minds of the Chinese people, hoping that an Immortal Emperor or Nakamoto congda God has made a kind of immortal coin, and the others are all from "Shanzhai". In the open source world, everyone has the right to make money. Any money is "counterfeit" money. Bitcoin was worthless before, and its value was given after the market recognized it. As long as another currency can also be recognized and accepted by the market, it is reasonable to give it a market value, and the amount of market value given is also determined by the market, which may not exceed bitcoin
assuming that the long-term market is effective, excluding speculation, whether a currency can be given value by the market mainly depends on several factors (I personally think)
bitcoin is an e-money payment system based on the global network
bitcoin is an e-money system based on the global decentralized network system, without the participation of central banks and third-party institutions, with a fixed total amount. Bitcoin has the characteristics of payment system and currency at the same time. Global network nodes are maintaining the bitcoin network all day<
English: bitcoin currency symbol: abbreviation: BTC or XBT
Introction to bitcoin by wiki
different from traditional currency, bitcoin's operation mechanism does not rely on the support or credit guarantee of central bank, government and enterprise, but on the network agreement reached with seed files in the network, which is a decentralized and self-improvement monetary system, Theoretically, it ensures that no one, institution or government can control the total amount of bitcoin or create inflation. Its total amount of money graally increased at the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140<
Introction to bitcoin in network
bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction<

the difference between bitcoin and bitcoin
it should be noted that
in English, the words bitcoin and bitcoin represent two concepts of payment network and monetary unit
bitcoin starting with capital B represents bitcoin network system or bitcoin network protocol, which is a payment system based on decentralized network
you can simply understand bitcoin as a public accounting system built on the Internet and not manipulated by any third party. Bitcoin, which starts with lowercase B, refers to the digital currency (e-money, e-cash, cryptocurrency) built on bitcoin network. Bitcoin is the payment accounting unit built in bitcoin payment system. We call bitcoin the network system that proces bitcoin<
in Chinese, bitcoin and bitcoin are both called bitcoin without distinction in many places
its main features are as follows:
1. Decentralization
bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom< Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership
private key is required to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost
bitcoin can be remitted free of charge, but in the end, a small transaction fee will be charged for each transaction to ensure faster transaction execution
5. No hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay<
6. Bitcoin is not completely anonymous

it will take some time to protect privacy when using bitcoin. All bitcoin transactions are publicly and permanently stored in the network, which means that anyone can view the balance and transaction records in any bitcoin address. Unless the bitcoin holder discloses personal information ring the transaction, the bitcoin address will not be associated with the real identity of the bitcoin holder. This is why it is recommended that bitcoin holders use multiple bitcoin addresses; In fact, you should create a new address each time to receive bitcoin. This is especially important when using bitcoin in public places, such as on websites. In addition, you can also consider using tools like tor to hide your IP address from being recorded.

7. Bitcoin is still experimental
bitcoin is an experimental new currency in active development. Although its experimentality is diminishing with its increasing usage, remember that bitcoin is a new invention, exploring ideas that have never been tried before, so no one can predict the future of bitcoin.
Fire coin is a bitcoin trading platform. As of the end of 2016, the accumulated turnover of fire coin reached 200 billion yuan
bitcoin is a virtual encrypted digital currency in the form of P2P
Bitcoin is different from all currencies. Bitcoin does not rely on a specific currency institution. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

back up your entire wallet
some bitcoin wallets use many hidden private keys inside. If you only back up the private key of the visible bitcoin address, most of the money may not be recovered from the backup
encrypt online backup
any online backup is easy to be stolen. Even a computer connected to the Internet is vulnerable to malware. Therefore, it is a good security habit to encrypt any backup exposed to the network
using multiple secure repositories
single point of failure is not concive to security. If your backup is not limited to only one place, it is less likely that something bad will happen and your wallet will not be restored. You can also consider using different storage media, such as USB flash disk, paper and CD-ROM.
keeping a backup of your wallet in a safe place can protect your wallet from computer failure and many human errors. If you encrypt your wallet, it can also be used to restore your wallet when your mobile phone or computer is stolen

regular backup
the wallet needs to be backed up regularly to ensure that all the latest bitcoin change addresses and newly created bitcoin addresses are included in the backup. However, soon all applications will use wallets that only need to be backed up once.
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chipuses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fastthe reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank youat the same time, Kushen users can set seed password and payment password to strengthen the multiple protection of Kushen wallet
the layered certainty of Kushen digital currency wallet allows users to manage multiple bitcoin addresses with a single seed password
Kushen digital currency wallet is easy to use. Kushen users can set service charges and multiple target bitcoin address book on the wallet to facilitate the management of multi account digital assets
Kushen digital currency wallet has only one screen as a single output device and only one camera as a single input device. He communicates with Kushen Internet app through two-dimensional code communication.
Generally speaking, blockchain wallet is used to store digital currency. In fact, blockchain wallet does not store digital currency, but a tool to store key (private key and public key). With the key, you can have the right to control the digital currency in the corresponding address, and use the digital currency collection address generated in blockchain wallet, You can accept the digital currency transferred to you by others, and you can also transfer the digital currency you own to others.
classification of digital currency wallets:
can be roughly divided into two categories, hot wallet (online wallet) and cold wallet (offline wallet)
first, hot wallet
Hot wallet is also called online wallet, It includes light wallets and heavy wallets (all node wallets). The wallets that need to be connected to the Internet can be directly traded
1. Light Wallet:
does not store the complete blockchain, only stores the data related to itself. It is small in size and can run on mobile phones, computers, web pages, etc
advantages and disadvantages: it does not occupy memory, supports a variety of digital assets, has a good user experience, is fast for novices, but transaction verification is a little slow
2. HEAVY WALLET (full node wallet)
maintains all blockchain data, completely decentralizes and synchronizes all data. It has better privacy and can verify the validity of transaction data locally
advantages and disadvantages: it has better privacy and faster verification of information, but it needs to synchronize data before each use, takes up a lot of hard disk space, and does not support multiple digital currency transactions
Second, cold wallet
cold wallet is not connected to the Internet, also known as offline wallet; For example, professional hardware devices, or private keys (mnemonics) written on paper
1. Hardware wallet
Hardware wallet is to store digital currency with professional hardware, store the private key of digital assets in a chip, isolate it from the Internet, and plug and play
2. Paper wallet
the advantages and disadvantages of writing the private key on paper and then deleting
cold Wallet:
is relatively safe, but it is very troublesome to create a wallet and trade. It is difficult for novices to operate, and the price of wallets is relatively expensive, generally ranging from thousands to tens of thousands of yuan. If you don't have a large amount of digital assets, you don't need to consider
generally, it's recommended for novices to use light wallet. Light wallet is easy to operate and easy to use. Personal used geekwallet
simple and convenient light wallet supports bitcoin (BTC), lightcoin (LTC), Ethereum (ETH), EOS Storage and management of mainstream digital currency assets such as usdt
using bip44 mnemonics, local private key, off-line signature and other security mechanisms, as well as mobile phone and computer al backup strategy, completely solve the loss of digital currency assets caused by hacker attack, virus infection, mobile phone loss, forgetting mnemonics and other ways, and provide users with online Multi Chain digital assets one-stop management service. The platform also has tiaoshao market, which can carry out token trading of physical assets on the chain
for consumers, digital wallets are free and easy to get. For example, when a consumer makes a purchase on a merchant's website that has set up a server-side digital wallet, he enters his name, payment amount and delivery information into the merchant's own form. At the end of the purchase, he was asked to sign the user name and password for the wallet of his choice. Users can also get wallets from the wallet provider's site
although wallets are free for consumers, the suppliers charge the merchants for using wallets.
digital currency refers to the digitization of currency. Digitization doesn't mean scanning. This is just like digital signature. Digital signature does not mean scanning your signature into a digital image, or using the touchpad to obtain the signature, let alone your signature. Digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, and that money is virtual. Of course, the virtual money will also have its real value. For example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing. Virtual money is not necessarily digital. For example, children play games with pebbles as virtual currency.
