Blockchain is first of all a traditional distributed system ; secondly , By technical means ( Hash 、 Public key system 、 Merkel tree, etc ) Built trust in all parties to the deal , Making anonymous secure transactions possible ; In turn, it makes all parties more willing to participate in the transaction , Let value ( Also with the help of similar ERC20 And so on ) Flow between nodes , Finally, the value Internet will be formed .
One dimension : The bottom chain -> All kinds of agreements ( Such as 0x、uniswap etc. ) -> Various applications ( game 、 exchange 、 Blockchain and other application technologies ); Another dimension : infrastructure ( Such as Infura)、 Tools ( Such as all kinds of Multi Chain wallets ).
The idea of digitalization has gradually entered the hearts of the people , After years of internal cultivation , Internal informatization tends to be perfect . With the further popularization of the Internet , Information integration among enterprises is the general trend . meanwhile , Technology is driving further changes in business .
The first two questions will be 【 Blockchain 】 Switch to 【 A technology 】 or 【 B technology 】 The same applies .
To some extent , Blockchain technology is an inter enterprise 【 Information Integration 】 Natural choice .
Direct operation node The most simple , But it's almost worthless ; According to their own business characteristics to build their own runtime It's development Substrate Apply normality ; The last one is similar to being implemented entirely in another language , Just follow the technical specifications Substrate standard , Similar to Ethereum multilingual client ecosystem .
however , I haven't seen the third way yet .
As far as my understanding is concerned ,Substrate runtime The ability to develop makes ink! It seems superfluous . Given that Ethereum is one of the biggest Ecologies for blockchain development , If you want to take advantage of previous technology investments , Consider introducing Substrate EVM modular , Accordingly , It also lists the main Ethereum development tools .
See also Substrate The document operates on its own .
The relationship between node and business can be compared to Tomcat And Web app The relationship between , You are planning to support multiple businesses with one node , Or do you plan to have one node for each business ?
The relationship between account and business is about authority , It's also analogous to :
One person is responsible for the business between enterprises
The spokesperson of an enterprise is responsible for all the business related to the enterprise
Dealing with different people at different stages of a business process
First ,Token Not a monster ; secondly , No use Token We all need to abide by laws and regulations . Use or not depends on the business process and business model .
There are different participants involved in different stages , Building a blockchain around such a scenario is valuable , And once on the chain , The relevant materials and archives are clear , It provides a foundation of trust for the next stage participants .
contrary , If you just focus on a single stage , Such as operation and maintenance , It may not have too much value .
in the final analysis , Blockchain should support the participants , To put it bluntly, it is also a support for a good business ecology .
Problems in sharing
1. How can different points between enterprises be connected through blockchain ?
answer : Can handle Substrate The node is implemented as a multi tenant integration system , The simplest design of each user's points is :( Enterprises id、 user id、 integral ); secondly , Realize the exchange gateway between enterprises , This exchange rate needs to be negotiated by enterprises themselves ; Last , We need to make sure that the general ledger is consistent , namely A Enterprises 100 Exchange points to B Enterprise 10 After integral , It needs to be increased and decreased .
At the same time, we also need to pay attention to the problem of how integral is generated , There may be different approaches according to different logics . One way, for example, is to , Exchange produces ; The other way is that exchange and production have nothing to do with each other , At this time, if there is no surplus B Enterprise points cannot be exchanged . In reality, there may be more .
2. How to determine the exchange rate ?
answer : This is more about business , Not a technical problem , It can only be determined by relevant business personnel .
3. It's very difficult for enterprises to determine the exchange ratio .
answer : ditto , The return of Technology , Business belongs to business ,.
