The relationship between small business chain and Ethereum
what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
although bitcoin and Ethernet are both digital currencies, unlike bitcoin, the main purpose of Ethernet is not to build itself as a payment substitute, but to facilitate and monetize the operation of Ethereum, so that developers can build and run distributed applications
eMule is better than BT's decentralization and more suitable for sharing resources.
there are 10 grades of steel procts: H40, J55, K55, N80, C75, L80, C90, C95, P110 and q125
proction range: oil casing
4-1 / 2 & quot
to
20 & quot
(usually seamless pipe)
button type: BTC, LTC, STC
for N80 casing, the manufacturer's proction length is R-1 (4.88-7.62m), R-2 (7.62-10.36m) and R-3 (10.36m-longer)
the surface defects of unqualified N80 casing include fish scale fold, slag inclusion fold and slag pit. When choosing the cooperative manufacturer, we should pay more attention to the time and place of the manufacturer
through negotiation between the manufacturer and the demander, submerged arc welded straight seam pipe can be used for large diameter casing (diameter greater than 508mm) used to transport natural gas, gas, oil, water and other liquids and gases
in order to rece the cost, improve the safety and prolong the service life of the casing of the demander, the type of pipe end buckle can be selected as long round thread, partial trapezoidal thread, short round thread and special buckle. The Demander shall specify the type of pipe end buckle in the contract when selecting< The mechanical properties control requirements of N80 raw materials selected by the manufacturer:
in order to make the mechanical properties of N80
grade (36Mn2V)
hot rolled seamless tube meet the API requirements, it is stipulated that the continuous casting slab is heated evenly, the starting rolling temperature is controlled at 1150 ~ 1220
℃, the rolling rhythm is well controlled, and the finishing rolling temperature is 920 ~ 950
℃< N80 oil casing pipe is a kind of seamless steel pipe with high strength and toughness.
the commonly used methods in the world are as follows:
quenching and tempering (including direct quenching and tempering after rolling), normalizing, normalizing +
tempering and tempering after rolling
36Mn2V
is a special steel for N80
grade oil casing, which belongs to microalloyed non quenched and tempered steel. The steel is suitable for processing by temperature control, cooling control and deformation control. The steel pipe can achieve the required performance without quenching and tempering, thus simplifying the proction process and recing the manufacturing cost of steel pipe
the demander's conversion of common units in the inquiry sheet of casing manufacturer: outer diameter 25.4mm = 1in, weight 1.49kg/m
= 1lb / ft, length 1m = 3.28ft.
It can improve the basic boxing proficiency, add a little at a time, add a little more at the highest level, a little more than the burnt yellow paper, the literacy level is greater than 1, and the basic boxing level is lower than 60. It can improve the basic fist and foot proficiency, reading literacy level is higher than 1 and basic fist and foot level is lower than 60

blockchain 1.0 mainly refers to bitcoin. Blockchain 2.0 extends to all assets, while blockchain 3.0 goes beyond currency, finance, even commerce, and all areas of our lives, including politics, social relations, ecation, medical care, etc. According to the prediction and conception of people in the instry, the era of blockchain 3.0 will be realized in the next five years. At that time, blockchain will be recognized and accepted by all the public like the Internet, thus completely subverting our lives
McKinsey has submitted a technical report on blockchain to the Federal Insurance Advisory Committee of the United States. The report calls 2009-2016 the "Dark Age" and believes that all blockchain solutions ring this period are based on bitcoin, and the new era of blockchain will begin in 2016. At that time, the application of blockchain will become unprecedented. Applying an original sentence in McKinsey report: Based on the current development speed of blockchain, we believe that blockchain solutions may realize their full potential in the next five years.
