Blockchain UTC

1.

Many places in China are experimenting with the use of digital RMB, and the convenience of digital RMB is as follows:

First: Digital RMB can be used offline

although mobile payment is very common now, any third-party payment software needs to be connected to the Internet. Alipay and WeChat also monopolize the third party payment market, but once these two software are not connected, they will not be able to complete the payment. Although it's all right to go out with your mobile phone now, you don't need to bring your wallet and cash, but all this is based on the fact that your mobile phone has electricity and network

The consumption habit of

is unhealthy, so digital RMB is actually a more real and planned payment method, which is helpful for young people to develop good consumption habits. This can avoid over consumption and other bad habits

2. bitcoin gold (BTG) is a branch of bitcoin, which can prevent ASIC from mining. Bitgold splits the bitcoin blockchain as planned after block 491406 (2017-10-24 01:17:35 UTC).

About dragonex dragon token

1, basic introction

Dragon token (DT) is a token issued by dragonex based on Ethereum erc20 standard, and each dragon token stored on the platform has the right of project dividend

every day, the transaction commission income of dragonex project will be distributed to all dragon coin holders according to the holding proportion of dragon coin

2. Mining method

longcoin can not be obtained through ICO or pre excavation

all dragon coins can only be generated in the form of "mining", and the only way of mining is to trade on the platform“ Miners (i.e. platform users) contribute to the platform through trading behavior, and the platform issues dragon coins to miners as rewards

the total number of dragon coins issued was 37339500, and promised never to be issued

3. Release rules of dragon coin

Dragon coin is a token based on Ethereum smart contract. Since the launch of Genesis, the smart contract will be released for a total of 3650 times, with an interval of 24 hours and a cycle of 365 times

in the first cycle, 51200 dragon coins will be released each time; The yield of each cycle will be 50% lower than that of the previous cycle

4. Longcoin distribution mechanism

the platform will make statistics on the mining situation of "miners" every day, and the statistical cycle is 0:00:00-23:59:59 on that day; Each time the smart contract releases the Dragon coin, the platform will allocate the new dragon coin to the corresponding "miner" account on the next day according to the statistical data

"miners" dig out dragon coins through trading behavior, but the excavated dragon coins are not 100% owned by miners, among which:

① "miners" get 30% dragon coin reward and

② market brokers get 20% dragon coin reward Market broker: if miner a uses the invitation link of user B when registering, then B is the market broker of user a)

③ dragonex project party gets 10% block dragon coin Award (frozen for one year: for project marketing)

(4) dragonex project party gets 40% block longcoin Award (permanently frozen: used for platform technology research and development, talent introction, project operation, buy back longcoin and destroy)

note: Singapore standard time (UTC / GMT + 08:00)

5. Longcoin dividend mechanism:

① 100% of the daily platform revenue will be distributed to longcoin holders according to the proportion of longcoin holdings

② the platform will take a snapshot of the balance of dragon coin holders at 23:59:59 every day. Since the Dragon coin g up on the same day will arrive the next day, the user can share the Dragon coin on the same day = snapshot data + dragon coin g up on the same day. Dividends will be paid the next day, in the form of usdt to each holder's account

③ dividend formula:

project party's income to be paid dividends = transaction fees + other income of the project

dividend income of currency holding users =

income to be paid dividends * [number of indivial dragon coins held / (number of issued dragon coins - number of destroyed dragon coins)]

6. Online time of dragon coins

Dragon coins began to "mine" and calculate dividends from November 2, 2017

e to the fact that Longyuan is still in the development stage, it can not be released to miners and market brokers. However, the project side will record the data of everyone, and after the development of longcoin is completed, the longcoin and dividends e to everyone will be distributed to the account

longcoin is expected to be developed before November 25, 2017, and will be traded online on dragonex platform. The specific online transaction time will be subject to the official announcement later

I believe there is a fraud in issuing digital currency, but there is a fraud in mining. Unless you buy a "nonexistent" mining machine or computing power, the probability of being cheated is almost zero. Next, let me talk about UTC's past and present lives

So, it's hard to say whether UTC is a fraud, but this model is indeed an innovation in the currency circle. After all, digital currency is getting more and more attention, and it may not become "currency", but it may become "alternative investment goods". Personally, I'm optimistic about this mining model

moreover, as far as I know, the team behind UTC, as well as the financial and technical support are quite reliable. If it is really a scam, the institutions that invest in UTC will not make such a big battle to cheat people

What is a timestamp? Time stamp is a complete and verifiable data that can represent the existence of a data at a specific time point. So what's the use of timestamps

function of time stamp

the client is making a request to the server interface. If the request information is encrypted and intercepted by a third party, the request packet can be used for repeated request operation. If the server does not carry out anti replay attack, the server pressure will increase, and the use of timestamp can solve this problem

tamper proof: the common way to use is to splice parameters, the current project appkey, the "key" agreed by both parties, and add them to the dictionary dictionary set, sort them according to ABCD order, and finally encrypt them in MD5 +. The client sends the encrypted string and request parameters to the server together. After splicing and encrypting according to the above rules, the server compares whether it is equal to the incoming encrypted string

anti multiplexing: encryption in the above way can not solve the problem of anti multiplexing. At this time, it is necessary to generate UTC timestamps on the client and the server respectively. This UTC is to prevent your client and the server from not being in the same time zone, hehe, Then the timestamp can be spelled in the ciphertext, as for the effectiveness of anti reuse.
