Two important milestones of blockchain
blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology 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
let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".
2. Blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era. In recent years, the development and application of blockchain is of great significance to technological innovation and instrial revolution. This experience introces the relevant knowledge of blockchain technology
3. Blockchain is a distributed ledger, which can contain financial and / or non-financial transactions. It can be replicated (distributed) on multiple systems in almost real time through peer-to-peer network. Each participant "owns" the same ledger and gets updated when adding any transaction. Each participant helps to determine the inherent "invariance" of all existing records, Using cryptography and digital signature to prove identity, authenticity and enforce read / write access, there is a mechanism that makes it difficult to change history, and it is easy to detect someone trying to change it.
Smart contract
smart contract is based on these trusted and tamperable data, which can automatically execute some pre-defined rules and terms, allowing trusted transactions without a third party, and these transactions are traceable and irreversible. The concept of smart contract was first proposed by Nick Szabo in 1995. The purpose of smart contract is to provide a better security method than traditional contract and rece other transaction costs related to the contract
The digital form of
extended data
means that the contract has to be written into computer-readable code. This is necessary, because as long as the participants reach an agreement, the rights and obligations of smart contract establishment are executed by a computer or computer network
to further explain:
(1) when the parties to the agreement
smart contract reach the agreement, the answer depends on the implementation of the specific smart contract. Generally speaking, the contract is discovered when the parties are committed to the execution of the contract by installing the contract on the contract host platform
(2) the real meaning of "execution" also depends on implementation. Generally speaking, implementation means active implementation through technical means(3) computer readable code
in addition, the specific "digital form" required by the contract is very dependent on the agreement that the parties agree to use
1. Banng Conference
in 1955, the Asian African Conference was held in Banng, Indonesia, also known as "Banng Conference". A total of 29 countries (18 in Asia and 6 in Africa) attended the conference. This is the first time in the history of the world that a large-scale international conference on the vital interests of the people of Asian and African countries was held by the independent countries of Asian and African nations without the participation of Western colonial countries. Premier Zhou Enlai led the Chinese delegation to attend the meeting. The conference adopted the final communique of the Asian African Conference, which includes economic cooperation, cultural cooperation, human rights and self-determination of the people in the dependent areas and the Declaration on promoting world peace and cooperation. The Banng Conference and its final communique embody the spirit of the struggle of the people of Asian and African countries to safeguard national independence, safeguard world peace and promote friendly cooperation, which is known as the "Banng spirit". The post conference communique of the Asian African Conference was widely quoted as one of the most important documents in post-war international relations because it represented justice, unity, friendship and progress. The five principles of peaceful coexistence, first proposed by China and jointly advocated by China, India and Myanmar, extend to the ten principles of peaceful coexistence for development, and are recognized by most countries in the world as universal principles of international relations
the Banng Conference is the first ever intercontinental conference of people of color. The convening of the Asian African Conference is of far-reaching significance not only in the history of Asia and Africa, but also in the history of the whole world. First, for the first time, the Asian African Conference has jointly issued a loud voice for the Asian and African people to oppose colonialism, safeguard and strive for national independence, safeguard world peace and promote friendly cooperation. Second, the Asian African Conference has created a new situation in international relations“ It marks that a new group of countries, the third world, has officially stepped on the international stage, and declares the end of the history of colonialists' hegemony in Asia and Africa. Third, the Banng Conference has effectively promoted the vigorous development of the Democratic National Liberation Movement. Fourth, the Banng Conference sowed the seeds of friendship, understanding and cooperation< In September 1961, launched by Yugoslavia, Egypt, Indonesia, India and Afghanistan, the first summit of heads of state and government of non aligned countries was held in Belgrade, attended by 25 countries. The conference adopted and issued the declaration of the conference of heads of state and government of non aligned countries and the statement on the danger of war and calling for peace, marking the formal formation of the non aligned movement. The non aligned movement pursues the purposes and principles of "anti imperialism, anti colonialism, anti hegemony and support for the national liberation movement" and "independent, non aligned and non bloc". It calls on the third world countries to strengthen unity, maintain world peace, and advocate the democratization of international relations and the establishment of a new international economic order. After the cold war, the focus of the movement has been graally adjusted and the purpose and direction for the future have been established: on the one hand, the movement will continue to adhere to the purpose and principles of the non aligned movement, oppose hegemonism and interference by major powers, and fight for the establishment of a new international order of peace and development; on the other hand, the movement will shift its focus to the economic field, The main task in the future is to help developing countries get rid of poverty, ignorance and backwardness
the non aligned movement is a proct of historical development, and its existence and development are in line with the historical trend. As a powerful political movement, he actively supported the liberation struggle of the oppressed nations, promoted the development of the national independence movement, accelerated the collapse of the imperialist colonial system, broke through the regional restrictions of the Banng Conference, faced the world, greatly improved the international status of small and medium-sized countries, and made positive contributions to the democratization of international relations; It has played a great role in opposing hegemonism of superpowers, launching an arms race, easing international tensions and maintaining world peace; Actively safeguarding the economic interests of the third world countries has made important contributions to improving their economic status, improving North South relations, promoting South South cooperation, and striving for the establishment of a new international economic order< The group of 77 is a group of developing countries established to safeguard their economic rights and interests, strengthen economic cooperation, and jointly oppose Western powers' control of plunder. The group's activities began in 1963. When the 18th UN General Assembly discussed the issue of trade and development, 73 Asian, African and Latin American countries and Yugoslavia and New Zealand jointly put forward a joint declaration, which was called the group of 75 at that time. In 1964, the number increased to 77, and issued a joint statement opposing unreasonable international economic relations, So the group of 77 got its name. In 1992, the number of members of the group reached 132, but the name has always been used
the establishment and development of the group of 77 is a milestone in the formation and development of the third world and plays an important role in the international arena. First, it has played a leading role in the struggle for the establishment of a new international economic order. Second, it has made positive contributions to promoting South South cooperation and safeguarding the economic rights and interests of developing countries. In 1964, the concept of "developing countries" was first put forward. In 1967, the Algerian charter adopted by the group first used the concept of "least developed countries". The group adopted a series of programmatic documents, which focused on the guiding principles of South South cooperation, strengthened the unity and cooperation of developing countries, and jointly opposed hegemonism and the oppression and exploitation of new and old colonialism. Third, we have made unremitting efforts and made great achievements in promoting North South dialogue and cooperation
in a word, the rise of the third world completely disintegrated the imperialist colonial system, greatly promoted the world's historical process, had a profound impact on the world's political and economic development, and brought about profound changes in the whole world that are beneficial to the people of all countries, world peace, and human progress. The rise of the third world is a major historical event in the 20th century.
