1. The difference between code chain and blockchain:
blockchain originates from the underlying technology of bitcoin and is the blockchain technology of Internet. IP is connected by blockchain technology to form distributed accounting. It is not easy to tamper with and decentralize
code chain technology is the code chain technology of the Internet of things, which superimposes the Internet of things IDS one by one in a two-dimensional way to form personal records. The application of "code chain" technology will bring more efficient link forms of "people to people", "people to things" and "things to things"
Introction to code chain:
"code chain" refers to a "two-dimensional code chain" formed by using a smart phone to aim at the "two-dimensional code" and "scan", that is, to "generate a new two-dimensional code containing the scanner's DNA" and access to the "service". The whole process can be traced, supervised and managed
"code chain technology" is the most widely used two-dimensional code "scan" payment technology
code chain technology can realize more efficient link form of people to people, people to things and things to things
Introction to blockchain:
blockchain is an important concept of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
the difference between code chain digital currency and blockchain digital currency:
the difference between "code chain digital currency" based on code chain technology and the existing blockchain digital currency is that "code chain digital currency" is based on the control of property rights, and uses "intelligent two-dimensional code" as the medium to transform the contracts of various instry chains into divisible, tradable, transferable, exchangeable Traceable "smart contract" and real right exchange within the code chain alliance. In the code chain monetary system, "intelligent two-dimensional code" means "SGR". That is to say, each commodity corresponds to a "smart QR code", and this "QR code" represents the "special reference property" of the commodity. Through special reference to the exchange of property rights, the exchange of goods (barter) can be realized. This two-dimensional code, which represents "special mention of property rights", can be used as the carrier and payment means of digital currency at the same time, and payment can be completed through "two-dimensional code scanning".

2. Compared with the past, various anti-counterfeiting technologies have been adopted in commodity traceability, but the results are not satisfactory. Using the traceability of blockchain technology, through the deep combination of logistics management, commodity anti-counterfeiting, commodity traceability, manufacturing management, instry collaboration and other fields, the traceability and security of commodities are increased. Cipher finance mimacaijing focuses on blockchain information.
3. This is part of the application of blockchain in the financial instry, and the feasibility of the integration of blockchain and bills is great
bill is a kind of valuable voucher, which needs a hidden "third party" role to ensure the safety and reliability of both parties in the transaction. However, with the help of blockchain, there is no need for a third party to supervise and verify the information transmitted by the two parties, nor for a specific physical object to be used as a proof to connect the two parties to obtain trust, thus realizing the "invisible" transmission of value between point-to-point
in the development of bill platform based on blockchain, Yingtang Zhongchuang said that the application of blockchain technology in the development of bill platform has the following functions: to realize the disintermediation of bill value transmission; Effectively prevent the risk of bill market; Change the existing system structure of electronic commercial draft; Improve operation efficiency; Standardize the market order and rece the cost of supervision
the advantages of the blockchain bill platform are as follows: the system construction and data storage do not need a central server, nor do they need a central level application; The integrity, transparency and verifiability of data can be traced and queried for any value exchange; The form of smart contract makes the bill programmable and controllable in the whole life cycle.

4. http://tieba..com/f?kz=913443610 This is a post of DNF gun god bar, which is specially about ignoring defense damage
then the test conclusion is that ignoring damage is equivalent to fixed attack power, which has nothing to do with your own attributes, level gap, and monster defense
specifically, there is no time. You can see for yourself. It's OK

5. Bitgem Asset Management Co., Ltd. (BAM) and its head office, precious Investment Co., Ltd., will launch the crowdsoale project for pinkcoin, its first cryptocurrency with diamond reserve. To be exact, pinkcoin is a cryptocurrency with fixed color diamond asset pool as reserve and based on Ethereum. Crowdsale project will be officially launched on January 18, 2016 at 9 am. Third party diamond insurance is valued one by one by Lloyd's group in London
a pinkcoin token will initially represent a point in the fixed valuation of the diamond pool. This represents the first fixed valuation of a dollar
the two companies said that the diamond pool would be valued regularly
pinkcoin can be converted into bitcoin or private gems according to the existing valuation of the diamond pool described in the terms of the crowdsole project. Initially, the asset pool was valued at $5 million, so the crowdsole project would contain 5 million pinkcoin tokens. BAM can issue 95 million new pinkcoin tokens in a non diluted way in the future
pinkcoin holders can convert it into other properties or tokens reserved by the asset pool in the bitgem retail market. The retail market will be open in the second quarter of 2016
users can trade pinkcoin with exchange providers or wallets that support token trading, and comply with the Ethereum standard contract APIs including Ethereum customer agreement
in fact, it may not be as big as he planned, and so is Fuyuan coin in China. Recently, it seems that it has encountered some problems. Down to earth is king. Bitcoin, Ruitai coin and Weimeng coin are developing slowly, but they are still developing steadily.
