Background of the founder of Ethereum
bitcoin is a digital currency designed by Nakamoto in 2009. The identity of its founder "Nakamoto" has always been a mystery. Rumors about "father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura. Matcha exchange can find out more about Ethereum bitcoin
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"
skycoin also includes the cancellation of mining incentives, the development of energy-saving customized hardware, the realization of transaction speed comparable to visa's similar projects, and the creation of a safer and more efficient Internet
the above achievements are realized thanks to the five robust component cores of skycoin ecosystem:
skycoin: a fast and secure currency supported by bandwidth
skywire: a truly decentralized mesh network
skyminer: hardware facilities to realize the real decentralized mesh network of skywire
fiber: an open decentralized blockchain network
skysuite: distributed application suite< The founder of skycoin is one of the earliest developers of bitcoin. Skycoin was founded eight years ago to create a new decentralized network. He is currently a consultant for several cryptocurrency projects. Synth has a background in mathematics, distributed systems and symbolic logic< br />✨ Houwu Chen, founder of
houwu is one of the developers of Ethereum and the author of the oblelisk white paper on the decentralized consensus protocol of skycoin distributed network and cryptocurrency. He studied for a doctorate in Tsinghua University.
Recently, a & lt; The 27 year old founder of ether coin made a profit of $1.1 billion; The news of, caused the hot discussion of broad netizens, make boiling on the net. We know that with the development of society, digital currency has emerged in all currencies. The largest digital currency is bitcoin. Bitcoin has risen from less than one cent at the beginning to more than 300000 yuan now, with a huge increase. After bitcoin, it is the second largest digital currency, ether coin, which was launched in 2015 and is now up a lot. So who is the founder? What does he do
The founder of vitalik buterin is a 27 year old programmer who created ethercoin in 2013 and launched ethercoin in 2015. He is a Russian Canadian{ RRRRR}the above are my views on this issue. They are purely personal views and are for reference only. If you have any different views, you can leave a message in the comment area for discussion
Ethereum, the world's second largest cryptocurrency, broke through $3000 for the first time on Monday, and rose further on Tuesday, once breaking through $3400, reaching a new high. Its market value once reached US $395.2 billion, ranking 18th in the global asset market value, surpassing MasterCard and NVIDIA and approaching Wal Mart. Traders attribute the rise of bitcoin to the rise of bitcoin at the end of 2020, and the upgrade of blockchain Ethernet makes bitcoin more useful. So far this year, Ethereum has grown by about 365%
bitcoin network is actually a distributed database, and Ethernet goes a step further. It can be seen as a distributed computer: the blockchain is the ROM of the computer, the contract is the program, and the miner of Ethernet is responsible for the calculation and plays the role of CPU. Of course, this computer is not and can not be used for free, otherwise anyone can store all kinds of junk information and carry out all kinds of trivial calculations
OK, that's what we're going to share in this issue strong>

logocentrism is another name of Western metaphysics, which is Derrida's general ruling on western philosophy by inheriting Heidegger's ideas. As the name suggests, logocentrism is a structure centered on logos, so we should first understand & quot; Logos & quot;
& quot; Logos & quot; From ancient Greek, for λ In the first volume of the history of Greek philosophy, gersley, a famous historian of philosophy, analyzed in detail the usage of the word "oyos" in philosophy, literature, history and other documents before the fifth century B.C., and summed up ten meanings: (1) anything spoken or written 2) Things mentioned and related to value, such as evaluation and reputation 3) The inner consideration of the soul, such as thought and reasoning 4) Develop from what is said or written to cause, reason or argument 5) And & quot; Empty talk& quot; Excuse & quot; On the contrary, & quot; The real logos & quot; It is the truth of things 6) Scale, propriety 7) Correspondence, proportion 8) General principle or rule, which is a relatively late usage 9) The ability of reason, such as the difference between man and animals, is that man has logos 10) Definition or formula to express the essence of things.
later generations mainly from & quot; Rationality& quot; Truth& quot; Law & quot; Even & quot; Logic & quot; To grasp & quot; Logos & quot; In Heidegger's being and time, this meaning is not groundless, but it is not its original meaning; Logos & quot; Far away from the basis of existentialism, & quot; Logos is experienced as a ready-made thing and interpreted as a ready-made thing; Similarly, the existential shown by logos also has the meaning of being; Therefore, he wants to put & quot; Logos & quot; From & quot; Logic & quot; In his opinion, he thought that "the first is to liberate and restore its original meaning"; Logos & quot; The original meaning is & quot; Talk & quot; Or & quot; Speaking & quot;, Its verb form is legein and its root is 1eg. The basic meaning of 1eg is & quot; Talk & quot Speech is the basic link of human being's Dasein, which forms the whole meaning of Dasein. It links human being's Dasein as a whole in the way of articulation; Heidegger's later period (from the introction to metaphysics in the transitional period) was not satisfied with the analysis of logos as & quot; Talk & quot;, Therefore, it continues to trace its origin, and holds that its original meaning is & quot; Aggregation & quot;, Gathering brings the miscellaneous and mutually exclusive things into the presence. Speech is also a kind of gathering, which makes all things gather into one and show up; Logos & quot; It is not only the omnipresent operation of being, but also the omnipresent operation of language; Aggregation & quot; To explain & quot; Logos & quot; And use & quot; Talk & quot; Explanation & quot; Logos & quot; Although there are differences between existentialism and ontology, they do not change the two core meanings, that is, to refer to & quot; at the same time; Speech & quot The speech of Dasein or being) and & quot; Presence & quot;, In & quot; Logos & quot; Derrida agrees with Heidegger's research that the pursuit of logos is the pursuit of all presence through speech; However, Derrida believes that & quot; Logos & quot; No matter it is in the normal sense & quot; Rationality & quot; Or & quot; Logic & quot; Or Heidegger insisted successively & quot; Talk & quot; And & quot; Aggregation & quot; In all kinds of metaphysical systems, there is always an unchanging presence as the center of its construction system. Derrida has a good summary of this in the opening of structure, symbol and game in the discourse of Human Sciences: there is a desire for center throughout the history of metaphysics, Different centers organize different structures; The history of the whole concept of structure must be regarded as a series of activities in which the center replaces the center, just like a chain of centers. The center obtains different forms and names in a way of successive emergence and mutual coordination. The history of metaphysics, like the whole history of the west, is the history of these metaphors and metonymies, It can be proved that all these names related to the basis, principle or center indicate an unchanging presence -- Eidos [essence], arche [origin], telos [purpose], Energia [energy], ousia [presence], existence [existence], substance [entity], Suiet [subject], Aletheia [Truth], Transcendentalite, conscience, Dieu, homine and so on; The historical manifestations of these presence are as follows: & quot; The presence of things as Eidos facing eyes, as entity / essence / existence, as temporal presence of present or moving point, as self presence of thinking, consciousness and subjectivity, as common presence of self and others; Derrida's philosophy is just a response to these various modes of presence. He re grasps logos from the perspective of signifying activity, that is, Heidegger's interpretation of logos from the perspective of ontology; Presence & quot; Interpretation is examined at the linguistic level (this is mainly influenced by Saussure, later on in detail): the so-called presence means that the signified is separated from the signifier. In the movement of signs, the signifier is originally indivisible, but metaphysics can make the signifier self erase and make the signified appear, and further regard the signified as the unchanging center and the basis of determination, In order to construct metaphysical edifice, Derrida called it & quot; A priori reference & quot According to Derrida, Heidegger's & quot; Logos & quot; Heidegger liberated language from logic, but constrained language in the presence of logos. Therefore, Derrida wanted to liberate language from logos (no matter what kind of logos it is) and classify it as the game's & quot; Words & quot In Derrida's opinion, logocentrism contains two rather contradictory views: first, it is a sound centered concept, namely phonocentrism. In the phenomenon of expressing meaning with symbols, the medium of sound is superior to that of words. Sound is internal and closest to meaning, while words are external, It can only approach meaning through sound circuitously, which is an ideological tradition based on Western phonetic characters. Secondly, in the activity of care, the sound must be hidden and self erased, so that the meaning can be completely and directly present. This is what Derrida called & quot; Metaphysics of presence & quot In this regard, sound centralism is attached to logos centralism, which serves for logos centralism. The only reason for its existence is to let logos lose its superiority when it is present
the climate is hot and humid in summer. When people sweat in hot weather, the watch may leave green or black marks on the wrist when it encounters sweat. Due to the different pH value in sweat, the degree of clock erosion is also different. Therefore, it is an important issue for watch lovers to take the initiative to maintain their watches
watch maintenance in summer
the reason why the watch turns green with sweat is that the watch factory adopts gold-plated copper-clad plating which is easy and beautiful in color, but if the gold-plated technology is not handled properly, it will cause the watch oxidation. Nowadays, PVD stainless steel plating technique is widely used in gold plating of watches and clocks, so it is rarely found. Therefore, it is recommended to buy stainless steel or K-gold materials. As for the problem of wrist blackening when wearing a watch, it is directly related to poor air quality and st stuck in the watch strap for a long time. In this case, it's best to give it to a professional watch shop for cleaning. You should also pay attention to the cleaning of the watch when you wear it on weekdays.
