In a narrow sense, a blockchain is a decentralized ledger in which blocks of data are assembled chronologically in a sequential manner into a chained data structure that is cryptographically guaranteed to be tamper-proof and unforgeable. Broadly speaking, blockchain technology is a new decentralized infrastructure and formalization of computation that uses block-chain data structure to verify and store data, decentralized node*** knowledge algorithms to generate and update data, cryptographic methods to guarantee the security of data transmission and access, and smart contracts composed of automated command code programs to program design and computing data.
Domestic blockchain application platforms include the digital currency crowdfunding platform CoinYing China, and the asset custody system based on blockchain technology developed by China Post and IBM.
What exactly is blockchain technology and why is it being speculatedBlockchain is a decentralized, node-participating, decentralized ledger system, on which the information stored cannot be forged or tampered with, and is open and transparent, and on which you can find the information recorded and the value owned by each account at any point in its history. The characteristics of the blockchain protocol provide the necessary basis for the execution of smart contracts, which can be automatically executed and trusted in accordance with the established conditions, without the need for auditing by any centralized institution.
Blockchain technology is the underlying core of the Bitcoin system, which is essentially a decentralized ledger. When people transact through the network, a new transaction will be recorded on the ledger, which is a decentralized ledger maintained by everyone in the network*** with the same, and people can see ongoing transactions at the same time, with control not in the hands of an institution or individual. The transaction cannot be tampered with, it cannot be forged, and it is permanently stored in the ledger.
As an example, the concentric mutual blockchain mutual aid platform, the application of blockchain technology has four major features:
Open and transparent
Open and transparent, all the information recorded on the blockchain, once recorded is difficult to tamper with, can not be hidden, the user at any time you can access.
Democratic Decision Making
Bottom-up Decision Making, blockchain proposes different **** knowledge mechanisms to help users effectively form bottom-up decision making and **** participate in major decisions.
Precise enforcement of rules
Precise enforcement of rules, the smart contract technology defined on the blockchain transforms all rules into public, clear program codes that can be precisely enforced, and no one can intervene once they are determined.
Never Downtime
Never Downtime, based on the public chain, the blockchain is not subject to the influence of any organization or individual, as long as the incentives are effective and the Internet exists, the blockchain exists.
What the hell is blockchain technology and why is it being hyped upWhat is blockchain? Blockchain is a technology for decentralized ****enjoyment bookkeeping, and what it's trying to do is enable the parties involved to establish a relationship of trust at a technical level. Blockchain can be roughly divided into two levels, one is to do the blockchain underlying technology; the second is to do the blockchain upper layer application, that is, based on the blockchain transformation, optimization or innovative applications. Blockchain is still in its infancy, a lot of people discuss with me how to ensure that at the same time and be able to confirm the right and be able to guarantee privacy, of course, now only in the exploration, both the entire network of impartial content and clear to be protected, this is what I can only talk about this, the future of the future I am so arranged.
Blockchain concept? Blockchain it is the idea of completely decentralized, is to rely on decentralized justice, that way the theory of the cost will drop a lot, proving that on the inter-network to the real assets and property rights in the inter-network direct correspondence. It solves the problem of decentralization and the problem of asset ownership that the first generation of Internet information did not solve, and now how big a role does big data play in financial innovation? Big data can only be used to register, in order to clarify who it belongs to, in fact, this has been our current problem can not be solved, this is not a small problem, any in the capital market there is a technology to the original is not clear property rights of the things clear property rights, that the whole market is a huge change.
What is blockchain? The blockchain technology itself can solve the data ownership, pricing and sharing mechanism. This is still not able to completely solve certain problems, to give a simple example talking about user privacy, I have a data placed on the machine, the cooperation party came over to do an insurance on the cooperation to analyze, there is a risk here is to give or not to give, is it possible to deal with a little bit or the laboratory property rights to be divided into a clear, and then the processing right, at the same time the right to data to say clearly that everyone produces the **** the same product is everyone *** same The, to be divided into different things, how to pricing, how to split, which in addition to the blockchain a decentralized repository of technology, talking about the above is the newborn task is another problem, and then up is the problem of pricing, this market mechanism, everyone all the field proved to recognize the rules, so this I think the blockchain is very good core technology, but can not cover all the problems.
Introduction to Bubi Blockchain
Bubi Blockchain's positioning is mainly to do commercial-grade blockchain infrastructure services, mainly including the creation of a blockchain system, and blockchain system and then build a support system with a high degree of expansion kit. And on top of that support system are applications for various industries. Bubi focuses more on the underlying technology of the blockchain, and in the past three years, a team of more than ten people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi blockchain chooses points has a little to do with the method of market promotion. As we all know, blockchain is a very suitable technology for digital asset issuance and trading, and points are a kind of digital asset that is naturally legal and compliant, and the impact is not too big because of the small amount. So it is a very suitable choice to take points as the first attempt to issue digital assets. The issuance of points based on the blockchain can also bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is just one aspect. In addition to reducing the cost of transferring property, blockchain technology can be used in a variety of areas involving company stock, financial derivatives, and loyalty programs for business organizations, to name a few. The blockchain community is now looking to advance the broader use of the technology in the financial asset space, and there has been significant investment in the various platforms that are still under development.
Blockchain concepts? They are very different in terms of structure or definition. The primary use of the US dollar, or any currency for that matter, by the typical definition, is to serve as a medium of exchange or store of value for economic activity. Within the geographic area in which a certain currency circulates, the people of that geographic area come to a ****ing understanding about the use of that currency, facilitating the use of the same currency by everyone to purchase goods or services (the medium of exchange function of money). There is a responsibility to manage money through monetary policy in order to ensure that it retains its value and to avoid inflation (the store of value function of money). In today's world, almost anyone uses some kind of currency in their daily lives.
What is blockchain? Even for developers who are within the blockchain community, it is often easy to lose sight of the big picture of the macros described above. There are a lot of competing projects within the blockchain community, and it's also full of all sorts of controversy about the direction of blockchain technology evolution. In time, some projects in the community will succeed, others will not be so lucky. Things won't always go the way we expect them to, but regardless of how these projects in the early blockchain community evolve, it is clear that blockchain technology brings us at least one revolutionary feature: it will dramatically reduce the cost of transferring financial property, and it will be used to control, manage, and transmit financial property.
What is blockchain? Blockchain concept? With a certain application analysis, let's go back to the beginning, this definition of blockchain technology is also bound to become richer and richer with the expansion of the application, and people will find out more about the wonders of blockchain technology.
Microsoft looks at the Bitcoin blockchain technology, in the end, what is itBlockchain (Blockchain) is an important concept of Bitcoin, essentially a decentralized repository, as well as the underlying technology of Bitcoin. A blockchain is a sequence of blocks of data associated using cryptographic methods, each containing information about a single Bitcoin Internet transaction, which is used to verify the validity of the information (anti-counterfeiting) and to generate the next block.
The blockchain is public on the net and can be queried in each offline bitcoin wallet profile. Bitcoin wallet functionality relies on confirmations with the blockchain, and a single validity check is called a confirmation. Usually several confirmations are obtained for a single transaction to take place. Lightweight bitcoin wallets use online confirmations, which means that they do not download blockchain data to the device's storage.
Many of Bitcoin's competing coins use the same design, with slight differences in proof-of-work and algorithms. For example, proof-of-stake and SCrypt are used, among others.
Blockchain timestamping services and proof of existence
The concept was introduced in Satoshi Nakamoto's whitepaper [1], in which he creates the first block, the "Genesis Block".
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left a never-to-be-modified sentence in the Genesis block:
"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks (2009) On January 3, the Chancellor of the Exchequer was on the brink of implementing a second bailout for banks)."
This was the moment when Britain's Chancellor of the Exchequer Darling was forced to consider a second bailout for the banking crisis, and this quote was the headline of a front page article in The Times that day.
With the blockchain's timestamping service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently preserved.
Bitcoin company BTCC launched a service in 2015 called "Chain of the Millennium", a blockchain lettering service that uses these principles. This service allows users to engrave text on the blockchain for permanent storage.
Bitcoin, Litecoin, Ritecoin, and Thousand Gold Card are all digital currencies based on blockchain technology.
What kind of technology is blockchain?Chongqing Jinwuwo analyzed that: blockchain is actually decentralized decentralized ledger database.
How hot is the blockchain technology
Blockchain technology makes DAC possible.DAC is something that can fundamentally disrupt the human social organization model. I believe its impact on society will surpass that of the Industrial Revolution and become the most profound change that the Internet has brought to the world.
Blockchain technology is essentially a decentralized and decentralized method of storing, transmitting, and proving data. It replaces the reliance on central servers on the Internet with blocks of data, and allows all data changes or transactions to be recorded in a cloud-based system, which theoretically enables self-proofing of data in the transmission of data.
Blockchain technology can be applied to a number of industries:
The art industry
Ascribe lets artists use blockchain technology to declare ownership and issue numbered, *** editions of their work, in digital form, for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without any intermediary services.
The legal industry
BitProof is the most advanced of the many file timestamping apps that have emerged in recent years, and will make traditional notarization a thing of the past. As opposed to free versions including Blocksgin and OriginStaemp, BitProof offers more services, including one for intellectual property rights. Interestingly, BitProof recently partnered with a San Francisco IT school to put all of their students' academic credentials on the blockchain, completely redefining how diplomas and student certificates can be processed and used.
Developing for the industry
Colu was the first to allow other businesses to issue digital assets, and their ability to "tokenize" a wide range of assets has impressed many. While the free Bitcoin wallet Counerparty also allows for simple tokens to be issued and traded between other wallet holders, Colu's tokens can be set to various states and types, can be detached from or re-entered into the system, and can be stored on the BitTorrent network when storing data on the blockchain becomes too large.
Net mutual aid industry
Musketeers mutual aid is the first landing and application of the blockchain net mutual aid platform, technology, through the blockchain and big data technology, eliminate the defects of the traditional net mutual aid model, to establish an open and transparent new net mutual aid platform.
What exactly is AITC?
Ait Cat is a virtual pet game produced under the blockchain technology, this virtual cat is similar to Baidu Lets Dogs, 360's pet cats, NetEase's Planet all belong to the same type of blockchain virtual products, then Ait Cat's difference lies in the design of the entire cat using the 3d stereo effect, so that the cat is no longer a picture of the display of the singularity of the cat, so that the cat can be moved to add the cat's interesting.
The cat's display is not a single picture.
