During this period of time, blockchain has expanded well in the Chinese market and formed quite a lot of investment management, which should be paid attention to. Today, Xiaobian will give you some answers. What should we pay attention to when we set up Singapore blockchain company as an agent in the Chinese market? Since the blockchain fire, quite a number of people have chosen to set up the main public guarantee company (Singapore Foundation) in Singapore

what attracts people in Singapore to do blockchain ICO projects? First of all, the Singapore government supports the expansion of the blockchain ICO at the beginning; Moreover, Singapore has perfect laws on blockchain ICO, which can provide similar legal services in the later stage; Thirdly, the establishment cost of Singapore is moderate; Here, the main companies of the big money circle must be the Singapore foundation

at present, the main bodies of blockchain projects are all established in Singapore as public Guarantee Co., Ltd., which is also known as Singapore non-profit foundation in the circle

registration process:

1) provide name verification

2) signing agency contract

3) pay 50% deposit

4) provide information of directors

5) submit data for registration

6) the registration was completed

7) pay 50% of the balance

8) send company documents

the non-profit Singapore foundation has won the recognition of block chain ICO practitioners with its own advantages. In the later stage, it can issue relevant legal opinions to do legal compliance, prove that the company's operation is in line with the current laws of Singapore, and avoid legal risks. After all, blockchain is a new thing in recent years, the supervision is not very mature, and risks and opportunities coexist. It is best to consider the legal risks and avoid them to the greatest extent while capital operation

2. Sha family
Sha (secure hash algorithm) is a series of cryptographic hash functions designed by National Security Agency (NSA) and published by National Institute of standards and Technology (NIST). The first member of the family officially named Sha was published in 1993. However, it has now been given an informal name sha-0 to avoid confusion with its successors. Two years later, SHA-1, the successor of the first Sha, was released. There are also four variants that have been released to enhance the scope of output and to change some minor designs: sha-224, SHA-256, sha-384, and sha-512 (sometimes referred to as SHA-2)<
sha-0 and SHA-1
the algorithms originally specified were published in 1993, which are called secure hash standard, FIPS pub 180. This version is now often called & quot; SHA-0" It was withdrawn by NSA soon after its release, and released in 1995 as a revised version of FIPS pub 180-1 (commonly known as & quot; SHA-1") replace. According to NSA, it fixed an error in the original algorithm that would rece password security. However, NSA does not provide any further explanation or proof that the error has been corrected. In 1998, in an attack on sha-0, it was found that this attack was not applicable to SHA-1 - we don't know if this is the error found by NSA, but it may indicate that this correction has improved the security. SHA-1 has been closely examined by the public password community, but it has not been found to be unsafe. It is now considered safe
sha-0 and SHA-1 will generate a 160 bit digest from a message with a maximum size of 2 ^ 64 bits, and then encrypt it based on the similar principle of Ronald L. Rivest, Professor of MIT who designed MD4 and MD5 message digest algorithms<
Cryptanalysis of sha-0
on crypto 98, two French researchers demonstrated an attack on sha-0 (chabaud and joux, 1998): hash collision can be found when the complexity is 2 ^ 61; Less than 2 ^ 80 is an ideal hash function of the same size
in 2004, Biham and Chen discovered the approximate collision of sha-0 - two messages can hash out the same value; In this case, 142 and 160 bits are the same. They also found that sha-0 dropped to 62 bits after 80 full collisions
on August 12, 2004, joux, carribault, lemuet and jalby announced the hash collision of the complete sha-0 algorithm. This is the result of the attack of chabaud and joux. The collision was found to be 2 ^ 51, and it took about 80000 CPU hours to work on a supercomputer with 256 Itanium 2 processors< On August 17, 2004, Wang, Feng, Lai, and Yu announced the preliminary results of attacking MD5, sha-0, and other hash functions at the rump meeting of crypto 2004. Their attack on sha-0 is as complex as 2 ^ 40, which means that their attack results are better than those of joux and others. A brief summary of the rump meeting can be found here, and their discussions in sci.crypt, for example, suggest that people planning to use SHA-1 as a new cryptosystem need to reconsider
longer variants
NIST has released three additional Sha variants, each with a longer message digest. They are named by adding their summary length (in bits) after their original name: & quot; SHA-256", & quot; SHA-384" And & quot; SHA-512" They were published in the draft of FIPS pub 180-2 in 2001, and then passed the review and comments. FIPS pub 180-2, including SHA-1, was released as an official standard in 2002. These new hash functions have not been tested in detail by the public password community like SHA-1, so their password security is not widely trusted. In February 2004, a change notice of FIPS pub 180-2 was issued, and an additional variant was added; SHA-224"， The key length required for double key 3DES is defined
Gilbert and handschuh (2003) studied new varieties and found no weaknesses<
shad
shad function is a simple restatement of the same Sha function:
shad-256 (m) = SHA-256 (SHA-256 (m)). It overcomes the problem of extended length attacks
applications
SHA-1, sha-224, SHA-256, sha-384 and sha-512 are all used by the U.S. federal government, which needs secure hash algorithms. They also use other cryptographic algorithms and protocols to protect sensitive unclassified data. FIPS pub 180-1 also encourages private or commercial organizations to use SHA-1 encryption. Fritz chip will probably use SHA-1 hash function to realize digital rights management on personal computers
the first to promote the publication of secure hash algorithm is the combined digital signature standard
Sha hash function has been used as the basis of shacal block cipher algorithm<
description of SHA-1
the pseudocode of SHA-1 algorithm is as follows:
(initialize variables:)
A = H0 = 0x67452301
b = H1 = 0xefcdab89
C = h2 = 0x98badcfe
d = H3 = 0x10325476
e = H4 = 0xc3d2e1f0
(pre processing:)
paddedmessage = (message) append 1
while length (paddedmessage) mod 512 & gt; 448:
paddedmessage = paddedmessage append 0
paddedmessage = paddedmessage append (length(message) in 64-bit format)
(Process the message in successive 512-bit chunks:)
while 512-bit chunk(s) remain(s):
break the current chunk into sixteen 32-bit words w(i), 0 <= i <= 15
(Extend the sixteen 32-bit words into eighty 32-bit words:)
for i from 16 to 79:
w(i) = (w(i-3) xor w(i-8) xor w(i-14) xor w(i-16)) leftrotate 1
(Main loop:)
for i from 0 to 79:
temp = (a leftrotate 5) + f(b,c,d) + e + k + w(i) (note: all addition is mod 2^32)
where:
(0 <= i <= 19): f(b,c,d) = (b and c) or ((not b) and d), k = 0x5A827999
(20 <= i <= 39): f(b,c,d) = (b xor c xor d), k = 0x6ED9EBA1
(40 <= i <= 59): f(b,c,d) = (b and c) or (b and d) or (c and d), k = 0x8F1BBCDC
(60 <= i <= 79): F (B, C, d) = (b XOR C XOR d), k = 0xca62c1d6
e = d
d = C
C = B leftrotate 30
b = a
A = temp
H0 = H0 + a
H1 = H1 + B
h2 = H2 + C
H3 = H3 + d
H4 = H4 + e
digest = hash = H0 append H1 append H2 append H3 append H4
note: FIPS pub 180-1 shows the concept of, The efficiency can be improved by using the following formula:
(0 & lt= i <= 19): f(b,c,d) = (d xor (b and (c xor d)))
(40 <= i <= 59): f(b,c,d) = (b and c) or (d and (b or c)))

The use method similar to appointment not only saves passengers' time, but also alleviates the situation that it is difficult to take a taxi in remote places to a certain extent

At the same time, the subsidy policy implemented by many travel software can also save some expenses for passengers, rece the burden of passengers, and increase the desire of passengers to take a taxi. At the same time, it solves the problem of "empty car rate" of drivers, makes it more convenient for drivers to check the surrounding tasks and rush to the source of customers in time. Its targeted order receiving method greatly improves the utilization rate of taxi resources, improves the income of drivers, and promotes the social and economic development

in addition, the third-party software companies seize the opportunity to seize the opportunity to put into use. Once they successfully occupy the market share, it means that the company will have considerable profits in the future

in a word, com car comes at the historic moment, which will lead to new changes in social proction, promote the upgrading of social structure, bring real convenience to residents, and will become a popular travel platform in the future

4. For new models that have just been launched, I think we should observe the feedback and consider it again, because the quality and reliability of new models that have just been launched still need time to test. In addition, if the sales volume of some new models that have just been launched is not good, they are likely to rece the price by a large margin immediately, so it is very cost-effective to start with.

the above is more fun. Some of them are not accurate. But they are definitely better than the building owner's own blind punching.
because a lot of things are made in the front to pave the way for the things behind.
it's very convenient for me to have a mining number. It only cost about 500 for my thieves to wash jewelry. All the materials are used to practice mining.
the materials of level 60 old world are very expensive There is no... we serve a relatively large server,
these materials are still very few. And they are very pitiful... A sapphire can sell to 50g...
after 300, you can use TBC materials very quickly. Magic iron and refined gold are still very cheap.. there is no one to dig.. no one grabs the ore.
the decomposed gems are enough for you to rush to WLK jewelry
this stage is the cheapest
and then start WLK level Duan.. green and blue gems are also cheap now.. it's very easy to get to 425..
it's up to you later..
I made a prism to rush up one day...
because thieves are trumpets..
it doesn't cost much to spend money. Now the price of gems is not so scary.
the price of minerals has also fallen miserably.
... So to sum up, the most pitiful ones are the gems of the old world... Those who follow the market What's more, ah can make you bankrupt
