Block chain is a living body, economies. Future block chain in the world can not do without its own measure of value construction
Public essentially different chains and chain Alliance
Block chain by all the attention should be October 2015. At that time universal in Shanghai to engage in a block chain Summit, because universal throughout the financial world more influential, with "The Economist" made a cover story called "trust the machine" in October , block chain began to be concerned about a lot of mainstream groups, especially financial groups. Block chain shared book itself is a technique, including asymmetric encryption, data block structure and the P2P communication, which combines a series of technical formed. The current scenario is mainly focused in four main areas: digital currency, recording as evidence, financial securities and intelligence contracts. Basically we talk block chain will be marked with this label: reliable, transparent, traceable, can not be changed, digital and more.
When the ants gold dress, we participate in the creation of the Ministry of Industry standard white paper block chain technology. 1.0 Block chain technology infrastructure, it would like to express it is basically Bitcoin. Block chain technology infrastructure 2.0, well explained to the Ethernet Square represented by block chain platform to put forward intelligent contracts, scripts can be executed in the block chain and judge it.
I have a basic view for the block chain classification. As you know, the public is divided into blocks chain chain chain and alliances in both directions, of course, a private chain, where we discuss, but more because of limited practical use within the enterprise, then do not block chain does not matter. Public chain block chain is an open community-based, enterprise-class alliance chain block chain. Public chain represents a non-trust based, non-privileged form of open block chain. But representatives of the Union is based on trust chain, block chain closed limited form of privilege, the two are essentially different.
The current block chain in the world of pain points
The current block chain pain points of the world focused on three aspects:
First, the mutual lack of interoperability between the block chain. Interoperability is a protocol across the chain, interact with information and assets between the chain and the chain. Interoperability is now inadequate, each block chain are islands of information.
Second, the slow progress in upgrading systems and protocols. Is 7 × 24 hours on the block chain nature, there is no way the system offline. Of course, this system is written by people, there will be bug, how to modify those bug? This is a very important issue. In addition to bug, how the system upgrade is also very important issue. Bitcoin on August 1 this year, there may be several bifurcation, it may produce a new kind of Bitcoin. This is also because its agreement no way to get a good upgrade, it produced a split system tokens and communities. Bitcoin upgrade issues have been controversial for several years, greatly reducing the rate of Bitcoin innovation iteration. We can see the Ethernet Square as well. Ethernet Square last year to do a fork, bring direct result of community split into two kinds of coins.
Third, the contract and the application can not be retrieved. We can say that Bitcoin is represented by one-dimensional linear world, because the electronic cash transfer is nothing more than you forwarded to me, I forwarded to you. Square with Ethernet as the representative of the second generation block chain system put forward the concept of smart contract like an open surface, there has been a two-dimensional world, so all of a sudden had a lot of interesting applications and intelligent decentralized to contract. When the block chain world is getting rich, not only exchange assets and assets inside there will be more and more applications and contracts, how to find information useful to the user, contracts and applications? This is also the challenges and pain points.
