The 7th blockchain in 2017
The following are the reasons why 2017 will be the most critical year for blockchain:
the lasting value of bitcoin
bitcoin, the initial tool of blockchain, ended 2016 with a high profile, which is a good omen
just after the new year, fortune reported that
"after the prosperity of 2016, the price of bitcoin has reached $1000, which has increased by 120% since the beginning of this year, and recently reached the highest point in three years. The reasons, including the devaluation of RMB, the risk of China's currency control and geopolitical instability, have been considered as the key factors for the success of cryptocurrency. Another reason for bitcoin's landmark year is its staying power - the longer it stays, the more familiar it will be, and more like a real store of value. "
whether it is fair or not, the feasibility of blockchain technology is always closely related to the performance of bitcoin. If the decentralized database can succeed in the financial field, it can also be widely used in other places. According to convention, the healthy development of digital currency has triggered a discussion on how to integrate blockchain into new areas. With healthy bitcoin, blockchain can expand rapidly in other fields
existing participants
of course, this has existed for some time, because the blockchain has been firmly bound to bitcoin. Over the years, many groups have invested a lot of money to apply the technology to a wider range of areas, while adding new features and creating new applications. If 2017 is a great year for blockchain, these existing players must be ready to grow with it
this trend is marked by the addition of 8 new members to the hyperledger project before the end of 2016. Software company CA technologies, blockchain project factcom foundation, healthcare alliance hashed health, Korean koscom, accounting company ledgerdomain, trade ecosystem developer lykee, sovrin foundation and telecom company Swisscom all joined in the project
Thehyperledger project has entered 2017 with an eye-catching membership list, and plans to introce blockchain feasibility case studies in actual use cases
new investment
the sign that the technology will make progress this year is that companies all over the world have laid the foundation for using blockchain status. Companies around the world applied for or accepted 356 patent applications related to blockchain or digital currency in November last year, almost double the number in the first month of 2016, according to the report of blog technology
Marc Kaufman, financial technology intellectual property expert at Reed Smith, told blog:
"we have witnessed an exponential growth in the number of patent applications, and we expect to see thousands of blockchain patents in the next five years."
the company is submitting patents in such a rapid way because the blockchain has finally achieved its goal from Utopia to digital ledger tool. With the increase of the number of patents, the new discovery of the index blockchain will enjoy wider legitimacy in 2017
it is only time to know the development trend of blockchain in 2017, and vice versa. However, it is obvious that the status of blockchain technology can be seen by all, which also proves the expectation of early investors for its potential and may develop new potential in the future
blockchain has also become a hot topic in the financial sector in China, and all major domestic financial institutions have tested blockchain projects. China Post and IBM have jointly developed a set of blockchain asset custody system; Puyin group launched the tea based digital currency Puyin
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
as people's misunderstanding of blockchain technology graally dissipates, we will see that next year, the financial services, insurance and medical instries will carry out comprehensive deployment of blockchain technology
blockchain technology will subvert our payment system internationally - the old profit model and other processes will become obstacles, and payment will become faster, cheaper and safer
however, as blockchain becomes more and more mainstream, we can no longer ignore the main obstacles on its development path. For example, the banking instry must develop a clear roadmap for blockchain adoption and cooperate on the basis of global standardization
2, the standardization process is about to start
with the more and more extensive application of blockchain, it will become extremely important to establish standardization methods between each other. But there are complex and political processes that can get in the way - there are conflicts of interest between instry organizations, and companies are trying to gain a clear advantage
with the implementation of various blockchain schemes, we will see that the situation will change to the process of standardization and integration. Once competing organizations graally realize the benefits of alliance and start to accelerate the trade process, strengthen detection and optimize data management
in 2017, there may be only a few dynamic blockchain alliances left, but instry players will have to cooperate and reach an agreement on a flexible and universal open logo. Governments and regulators will also play an important role in protecting consumers and encouraging innovation
stakeholders driving the development of blockchain standards will need to be creative and can envision a future in which these standards can be used to create new and powerful tools
3, fintech is accelerating development
fintech is bringing great changes, from simple payment to complex global financial operations are being subverted by it
the in-depth changes that are expected to happen next year are as follows:
blockchain combined with machine learning can jointly accelerate the existing process and optimize efficiency
emojis, payment, will be more widely used, and mobile devices will become more and more secure
lending network will become one of the hottest areas of blockchain
all countries in the world will be more interested in the development of digital currency
4, it's time to subvert the field of payment
in the field of payment transaction, blockchain technology is used to overcome the problems existing in the agent banking system and international remittance
there are many proceres and incoherent processes in cross-border non cash transactions, which can be eliminated by eliminating the third-party institutions, direct currency transfer and efficient inter-bank settlement. This possibility of creating a competitive market for liquidity providers may ensure the optimal exchange rate for international exchange and payment transactions
payment systems are based on local banking regulations and practices, but lack of common standards, which reces the ability of seamless transmission of data and background information, and brings settlement and non settlement risks
the extensive implementation and use of blockchain will change and subvert the existing financial services instry and payment system on a global scale
in addition, although the blockchain was very popular in 2016, there was very little substantive progress. Only coin Ying China and China Post really put it into practice, and other projects just stayed in the theoretical stage.
under the ideal situation of big bird mount + no one grabs the mines with you + opposing camp doesn't kill you + familiar with the mines, more than 1000g per hour
under normal circumstances, e to various interference factors, 500g per hour is good, minus 200g per hour, the actual income is 300g per hour, If you are engaged in manual mining, you should also consider the fatigue factor. The more mining, the lower the efficiency. It is not recommended to use this lowest level method of earning money. Just like the wage earners in big cities, they can barely earn a living (point card money), but they have no future
In 2014, Barry Silbert, founder of secondmarket, separated the bitcoin investment fund from the original company and established grayscale investments
in 2015, gray investment company was merged into the newly established digital currency group (DCG). DCG is not only focused on digital currency and blockchain investment, but also an incubator for start-ups. In addition to gray investment company, DCG also has two subsidiaries, namely, genesis, a cryptocurrency OTC broker, coindesk, a blockchain news and information website, and more than 150 other blockchain companies / projects invested
after years of development, gray investment company has become the largest cryptocurrency asset management company in the world, and its cryptocurrency trust scale has reached US $2.58 billion
{rrrrrrr}
extended information:
in 2013, Barry Silbert, the founder, convinced the board of directors of secondmarket company to set up a bitcoin investment fund called bitcoin investment trust, which is the predecessor of gray scale bitcoin trust. It was not until September 2017 that gray investment's bitcoin trust fund began to grow explosively
it has become the largest bitcoin investment trust in the world, with more than 408500 bitcoins, nearly 2% of the total. In addition to bitcoin trust funds, gray investment company also launched BCH, ETH, etc, horizon, LTC, XLM, XRP and Zec trust funds, as well as grayscale digital large capital fund with mainstream currencies. Gray investment company's cryptocurrency trust procts provide convenience for institutional users to purchase cryptocurrency
