Update frequency of digital currency code
transaction security technology includes anonymous technology, identity authentication technology, anti plicate transaction technology and anti-counterfeiting technology. Anonymity technology realizes controllable anonymity of digital assets through blind signature (including blind parameter signature, weak blind signature, strong blind signature, etc.) and zero knowledge proof; The identity authentication technology verifies the user's identity through the authentication center to ensure the validity of the digital asset trader's identity; The anti plicate transaction technology ensures that digital assets are not reused by means of digital signature, serial number and time stamp; Anti counterfeiting technology ensures the authenticity of digital assets and transactions by means of encryption and decryption, digital signature and identity authentication. Secondly, the online transaction and offline transaction of digital assets are realized by transaction technology. Digital asset trading technology mainly includes online trading technology and offline trading technology. As a legal currency, digital assets should not be rejected by any unit or indivial, and can be traded online or offline. Online transaction technology realizes online transaction of digital assets through online device interaction technology, online data transmission technology and online transaction processing; The off-line transaction technology realizes the off-line transaction of digital assets through the off-line device interaction technology, off-line data transmission technology and off-line transaction processing technology. Finally, trusted guarantee technology is used to provide a safe and reliable application environment for the issuance, circulation and transaction of digital assets in blockchain. Digital asset trustworthiness assurance technology mainly refers to trusted service management technology. Based on trusted service management platform (TSM), it ensures the security and trustworthiness of digital asset security mole and application data, and provides security chip (SE) and application life cycle management function for digital asset participants. Trusted service management technology can provide application registration, application download, security authentication, authentication management, security evaluation, trusted loading and other services for digital assets, which can effectively ensure the security and credibility of digital assets system
what is blockchain? Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records. Blockchain technology development blockchain technology development what is a blockchain system? Blockchain system is a database system with integrity. The data written into the system will be automatically copied to the nodes of the blockchain, which can achieve transactional data preservation, support the management and development of databases in various instries, and be proced in combination with various needs. 294.497 billion US dollars, or 2.60%. This week, five new projects entered the top 100, namely FST, ZB, Wix, wax and MXM. On August 11, the price of bitcoin was $11523.58, up 3.20% from last week, and Ethereum was $216.09, down 3.86% from last week. The 24-hour turnover of this week increased by 2.63% over the same period last week; Among the top 100 projects, the total market value and average market value of currency projects increased significantly, and the classification composition of global blockchain assets top 100 projects was stable.
The globalization process of digital currency is still progressing steadily. All countries are trying to develop their own blockchain applications and have great expectations for the innovation brought by new technologies. However, ordinary people do not seem to be very interested in these technologies. They prefer to get benefits from blockchain technologies, so more people still learn blockchain because of currency speculation, The threshold to enter the blockchain instry itself is very high. Basically, in the early stage, it was the technology God that entered. Later, some financial practitioners with foresight entered the instry through the currency circle, and then the capital market led by 3M poured into bitcoin and Leyte, which gave birth to the whole bull market of digital currency, Then we knew everything about it, which triggered a new crowd financing, which gave rise to the bubble and then returned to the present value. p>
the result of this round of market is to let the people of the world realize what blockchain is and what blockchain can change. Some scholars and experts really participate in the blockchain instry, drive the whole economic system to study blockchain technology, and directly establish the blockchain instry as the general trend in the next 5-10 years. It seems that ordinary investors can only invest in digital currency, which makes it easier for them to overtake on the curve of wealth. Therefore, if we love the coin circle, we should cultivate it deeply, because the existence of the coin circle has become a trend, and it is a sunrise instry at least. On the contrary, if you are curious about blockchain technology, you should also practice it well. In the future, central enterprises, state-owned enterprises and listed companies will need talents who understand blockchain. It's better to understand the code together. In any case, it will be easier to make money in the tide of trend. Choice is more important than struggle
market analysis
bitcoin:
6600 did not break down effectively yesterday. Your breakthrough selling point in yesterday's hour chart is a good application. Look at the chart:
< img Src=“ https://iknow-pic.cdn.bcebos.com/a2cc7cd98d1001e9c8925f8cb40e7bec55e79783 "/ >from the day before yesterday, Bitcoin continues to gain support in the important position of 6600. As you can see, the trading volume that touched 6600 before was relatively large. Yesterday's small trading volume falling below 6600 platform support is not an effective breakthrough, and it does not constitute the large volume falling below. Therefore, it is a false breakthrough, so it was pulled back soon after falling below 6600. From the trading volume of the big Yang line, Similarly, it is not big, which indicates that bulls only hold the key point for a short time and have no ability to reverse the trend
bitcoin has come out of a small bottom. Yesterday, it was said that if 6600 stands, bitcoin will have a concussive rebound at this position. However, it is expected that the rebound will be limited, just extending the time of decline. Therefore, the market has stabilized 6600 for three consecutive days and established a small bottom of 6600
judging from today's rebound trading volume, it is still insufficient, so the short-term rebound range will not be too large. The strong pressure level above is around 7700, and the energy of bulls in this round is limited, so 7700 is regarded as the rebound limit for the time being, and the big downward trend still remains unchanged, There are local opportunities in the short term. The position should still be below 30%
eth:
like the daily line, bitcoin has almost established a small bottom, which will be accompanied by a certain rebound, but the overall situation will not be very strong, so it is still a linked market. The specific analysis method has been given to you yesterday, using the K-line of various currencies and bitcoin to make a comparison, and then select those currencies that are willing to operate, and find out the currencies that are likely to rise, Only the large market value currency is valid for the K line of usdt
ADA, xvg:
yesterday, I compared the two charts with the trend of bitcoin, and gave the conclusion that the main force of xvg is willing to control the price of bitcoin in the short term, so the independent market of xvg rose continuously yesterday and today. This is a good case of converting the chart into language through the technical analysis of disk. If you can draw such a conclusion through the comparison, I believe the probability of making money will increase greatly. The same is true of ADA. If we compare it with March 18, bitcoin has fallen far below the low point of 3.18, while ADA is still hovering and stabilizing at 3.18, which is also a signal for the main force to enter. However, by comparing with xvg, we can draw the conclusion that ADA is long-term and xvg is short-term hot money behavior. If someone ambushes xvg after reading the article yesterday, they can hold the money along the 5-day line for the time being. The coordination of quantity and price is not bad, and the washing up is quite sufficient. They have the will to continue to rush up
LTC:
take out the diagram and compare it with BTC to understand why linkage has been mentioned all the time. Let's not talk about it. It's still two words: linkage
in the past two days, the price of currency has not been speculated, and some teams have begun to do the same trick again, forking out candy. No, OMG and BTG are clamoring to fork out and give forked currency. However, it is difficult for these news to stimulate the price of currency again. After all, what they split out is not a star project, so it is difficult for people to have the desire to buy currency for candy. So this kind of message can be evaluated as neutral
recently, some currencies cooperating with large companies have gone well. If you want to speculate, you can think along this main line. If you want to find relevant information and do some latent work, you may have good short-term opportunities
there are not many other things to talk about. The money making effect is still not strong. mining and hoarding money are the main factors. Generally speaking, the trend of money price is weak. The bear market makes money, and the bull market makes money. Digging money is more suitable for the current market than frying money. Now we know that the decline of money price leads to the decline of mining machinery. Once the money price recovers, the mining machinery will rise in a positive proportion, so we can rest assured to invest in digging money. After all, if the currency price exceeds 7700, don't keep catching up. It's easy to lose more than gain
network virtual currency can be roughly divided into
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. Mainly used for Internet financial investment, can also be used as a new currency directly for life
popularity: there is no doubt that bitcoin and lightcoin have the highest popularity in the cryptocurrency circle. Even though they have many shortcomings, they still have the largest number of players and the highest amount of money. They have large plates and are not easy to be controlled by the makers. Of course, the relevant infrastructure is relatively perfect
Innovation: dog coin is popular because it caters to the western small reward culture. The reason why Fuyuan coin can become the leader of the new generation of cryptocurrency is that it mainly focuses on the currency business circle, which is an applied cryptocurrency
operation mode: for example, the operation mode of Vicat coin has been exposed as pyramid selling. Although Yuanbao coin has been criticized before, the operation team will not give up, and Yuanbao coin is still the leader of domestic currency.
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block.
