the block chain , in the current industry is already in full swing . block chain in the industry to solve ideas , bright spots are all top - level design , production , finance and so on . This paper from both ideologies links going back over the blockchain technology , including the concept , advantage and how to go to the centre of discussion and so bold .
What is blockchain
For those not familiar with the blockchain , the blockchain might surprise you . I ' m thinking it a couple of people have not heard of it .
the block chain is capable of increasing infinite computational power , speed and safety of the promising technology . By eliminating the " intermediate layer " , and the safety speed will automatically increase , which in itself increases in computing power .
Today many startup company starts to follow the block chain , banking , insurance , video , game and other industries and companies are seriously considering a chain block , or already in use .
In fact , most have heard of the blockchain might automatically associate the bitcoin revolution .
the inventor of the blockchain is one person or team , known as Satoshi Nakamoto ( Japanese ) , he is also the inventor of bitcoin and design . Bitcoin is a peer - to - peer transactions , meaning that there is no intermediary . transaction by the network node , and then recorded in the blockchain .
So specifically , what is the blockchain ?
Briefly , the blockchain is the public pocket book .
the block chain is a growing " block " list , they are linked to each other and use encryption technology to protect the records . Most of us heard it , this wonderful invention almost synonymous with bitcoin . However , this is just the beginning .
block - chain technology has incredibly fast and safe , an on - going " slowly " and risky business . Especially with hacking becomes more and more powerful , and the block chain is no longer replicated information , but the distribution of the information . No " maybe " , the block chain will have a dramatic development , it is possible to create an entirely new type of Internet backbone .
Bitcoin transaction operates on the principle that someone somewhere in the requested transaction , then the transaction is broadcast to the P2P network , which is called by the network node of the computer .
the network node using a known algorithm to verify that the transaction state and user state . Verified transactions may involve cryptographic currencies like Bitcoin , protocol , or other digital information to be recorded .
Once the transaction has been verified , it will be combined with other transaction ledger is to create a new data block , the new data blocks are to be added to the existing data block in the chain . This entire process is permanent and cannot be changed . At this time , the transaction is completed .
In 2015 the Institute Don Tapscott pointed out : the most basic of the blockchain is global spreadsheet for cheap digital ledger , and programming may be recorded as financial transactions . But almost all of it may be recorded as an important human value : birth and death certificates , marriage certificates , title deeds , educational degree , financial accounts , medical procedures , insurance claims , referendum , smart objects between the transaction and any other available code . This account represents truth , through mass collaboration and constant perfection .
This is definitely a good news , think of us as a real - life protocol while the things we ' ve done before signing to assess them all , even with respect to the retaining of a lawyer . using the blockchain has inherently a large number of real information available , it is possible to immediately verify or deny out of hand .
Tapscott said , adding that some people think , the double - entry bookkeeping , the entire contents of which are the achievement in the nation and the country prosperity , if new digital recording platform capable of achieving reconciliation , reconciliation also referred to as digital . Everything requires a unified ledger , all commercial and economic achievements of the precise numbers and metering . To World Wide Ledger is ready , the blockchain will make on the planet and nationalism and conspiracy theorists of the spine to feel a little cold .
Whether you like it or not , the blockchain technology will break down borders , one is able to accurately track each company ' s global single government opened the door . Failure of the minority in the " system " within the person may not be able to obtain any services , including food , medical and other basic services . In one exceeded 70 billion people on Earth , many see a single , fully integrated with the centralized global system , it is possible to ensure that each member in a sandbox to play very well , with sufficient food and appropriate medical care and other benefits .
An alternative definition of the manner in which the block chain , which can be handled as a single distributed database . It is equivalent to a large computer network on the repeated thousands of times Excel document , all of the blocks of the chain network design enables a local file updated on a regular basis .
stored in the block chain on all the information is shared and regularly update a part of the database . Since the database is not stored in a single location , its record is , it is easy to verify . data is not stored in a central node , it is impossible for hackers breached all of the server . while at the same time data hosted on millions of computers , but anyone can access data from anywhere .
block - chain technology has an advantage ?
Now just like 2000 years before the internet of an early stage , the developer should open all possibilities in order to learn the blockchain technology . However , we can still rely on previous technologies by virtue of the accumulation of learning and practice .
For example , such as file - sharing . In the blockchain technology does , we have always done is to let people send documents , others modify it . He then waits for the modified file returns , after we received and we will see a change . If you still have the defect , the user has to repeatedly revised several times .
The two positions of two different people , even in the same position on the computer , also cannot simultaneously in the same database on the work . The traditional system will lock one of the user , until the other person can use to logout .
banks in the same manner as in the work . Every time a request to transfer funds from one customer to another customer ' s account , they must spend time and resources in coordination , synchronization and check to ensure that the transaction is fully expected to occur . For example , each time an online transfer , funds held by the founders , until receipt of confirmation of funds received is successful .
Imagine , for a domestic or international banks , this time is quite expensive .
block - chain technology has been eliminated and a lot more than this cumbersome process , because it uses a single transaction ledger and they are entitled to access the database only recording . while the protocol is simplified and the verification process , which saves the time and resources , and , of course , money .
the blockchain technology safe ?
looks a lot like the Internet , the blockchain and not by a single machine even small LANs , a type of network , has the robustness . Regardless of whether a server failure , and even some servers are down , there is no relationship . block chain that looks a lot like the Internet , from a large server cluster is configured .
because the same information block is stored in the network , the block chain cannot by any control entity , and cannot have a single point of failure .
Bitcoin is the obvious example of this is that Satoshi Nakamoto invented in 2008 , 2009 , and released the first version . Thereafter the digital currency that has been operating without any apparent interruption .
Perhaps the biggest - ever regret there is basically one in which the initial dig in around 7500 bitcoin at the British , but he didn ' t really see the future as well . When his computer crashed , and he put the host is taken out from the hard disk , which contains his Bitcoin " wallet " , then he will be a hard disk in a drawer for a period of time , finally it is thrown into the trash . his supply , bitcoin ' s development and we now know , not only persisted , but also to increase exponentially . When he ran to the landfill looking for old hard drives , it was found to be buried in a landfill about 2 feet , covered with an estimated 25 million cubic meters of debris and soils .
In addition to the above - mentioned heart - wrenching story , there are a number of computer hacking and mismanagement and other issues . with the bitcoin blockchain - related questions came from human error and malicious attacks . It ' s like the Internet itself , the technology underlying the blockchain is not a problem .
Since the blockchain network maintain a continual open condition exists , and automatically checked once every 10 minutes , so it is neither transparent , nor the destruction . It uses digital self - test system , the network every 10 minutes for automatic coordination of a transaction .
Indeed , no one can destroy the block chain on any of the information unit . Because of the whole network changes to the powers required by the will of the calendar .
Who can control block chain ?
this exciting technology is one of the truly interesting facts , it is its impact upon business .
no man control block chain . In other words , it is the design of a distributed network . In a peer - to - peer network on the basis of their own under the management of the operation . Bitcoin has now been widely accepted around the world , it is managed by the network , rather than by any central authority . Such architecture has more powerful ?
The latest example is China trying to crack down on user and control its concealment of the territory . This makes the rest of the world briefly , we have witnessed a bitcoin was worth the short - term decline . With the release of the policy , after a month , and maintaining the momentum of bitcoin .
Indeed , it is this very distributed design not only lets the bitcoin become mainstream , but has now been created hundreds of new cryptocurrencies and new terminology : ICO ( initial coin products ) . As for the property using the blockchain technology is completely unregulated , often highly risky . ICO is becoming like the start - up the implementation of the capital of the most popular crowdfunding . When the ICO for a little while , " casting " of the encryption of a certain proportion of the currency would accept cash or other component of an established encrypted money .
By 2017 , there are 400 more in the ICO ' s financing . Yitai Square by 2013 , and 2014 by crowdfunding the development , growth and development in 2015 . ICO has become the leading of the blockchain platform , holding more than 50 percent of market share .
As of December 2017 , the ICO to continue more than 20 above the rate of occurrence . Nobody knows what ' s going to happen , or how this will affect the value of money . ICO is very useful for many things , including its financing and charity fund - raising , but also full of a lot of fraud .
That ' s why governments around the world are working on how to manage it . Does this mean that they would oversee the blockchain technology itself ? They can ? Whether any government for the successful management of the Internet ?
reality of solving method , the specification of only the block chain method , is turned off . With the popularity of smart phones , portable solar battery and satellite Wi - Fi coverage can be almost anywhere on earth , " pulling the plug " also becomes less realistic .
Who will use the blockchain ?
Since the blockchain can eliminate intermediaries in financial transactions , and financial institutions therefore need to change their business model . After all , they are by far the biggest financial " intermediary " .
By the block chain , the user may be a point to point on the basis of almost any transaction of the transaction , without any bank involvement . Although the bank will likely lose its intermediaries , but now many banks are provided and various encrypted transaction currency of associated services . They also use the blockchain to do the record - keeping management and other aspects , the tremendous cost savings . banks and others are scrambling to hire the blockchain developer . Experienced developers may be able to claim the blockchain almost whatever they liked for a salary , seems to be the billable hours .
- is only now beginning to see the blockchain will take us . Some people also called Web 3.0 , seems more apt . block chain and their derivatives of the new business application of great potential in itself is another article , perhaps even beyond .
You will learn the blockchain ? Are you going to use it ? Maybe you already are one . If you ' re not , are not aware of the blockchain technology , it ' s time to take a look at it .
