“ Boca knowledge map ” It's our entry-level article on poca from zero to one , Let's try to start with the most basic part of Boca , To provide you with a comprehensive understanding of the contents of Boca , Of course, it's a huge project , And it's full of challenges , However, we hope that through such efforts, we can make people correctly understand Boca , It also makes it convenient for people who don't know poca to master poca related knowledge quickly , Today is the third day of the column 40 period , To get to know Polkadot And Kusama What is the difference between two independent networks ？
Boca and Kusama The current parallel chain slot of the network Auction Have entered normalization , Although they use similar code bases to build , But at the changing frequency 、 The application threshold is different .
In order to ensure that the project can have a more stable state before launching Boca network , Almost all projects will be in Kusama Testing and iteration on the network .
however ,Kusama And Boca are still independent of each other , also Gavin Previously said Kusama It's not just a test network ,Polkadot and Kusama Are independent networks with different priorities .
Kusama It's wild and fast ; Ideal for bold experimentation and early deployment .Polkadot More conservative , Give priority to stability and reliability .
After all, there are differences between cousins .
What do the two networks have in common ？
Kusama Is used for Polkadot An earlier version of the same code was released , This means they share the same underlying architecture ： Proof of interest based on nomination （NPoS） Multiple chains of 、 Heterogeneous fragment design .
The two networks also share key innovations , Such as chain governance 、 Heat exchange without bifurcation Runtimes、 Chain upgrade and cross consensus messaging （XCM） Interoperability of .
Polkadot and Kusama Governance is designed to be decentralized and unlicensed , Let have a native pass （Polkadot by DOT,Kusama by KSM） Everyone can have a say in how the network works .
therefore , as time goes on , These networks will develop independently according to the decisions of their respective communities 、 Fusion or differentiation .
The main difference
There are several important differences to explain .
These two networks also have different circulation and supply .
Polkadot and Kusama The first key technical difference between is ,Kusama Modified governance parameters , For faster upgrades .
Kusama Faster than Polkadot Four times faster , The pass holder can 7 Vote on the referendum within days , And then there was 8 The promulgation period of days , After that, the referendum will be issued on the chain .
This means that if stakeholders want to keep up with all proposals 、 Referendum and escalation , You need to be active and alert , and Kusama Verifiers on usually need to update in a short time .
stay Polkadot On , The vote continued 28 God , And then there was 28 The promulgation period of days .
It doesn't mean that Kusama Blockchain itself is faster , In terms of block time or transaction throughput （ These are the same on both networks ）, It means shorter time between governance events , For example, propose a new referendum 、 Vote and issue approved upgrades . This makes Kusama Be able to compare Polkadot Adapt and develop faster .
Teams that want to run parallel chains need to bind a pass as a guarantee .Kusama Binding requirements may be lower than Polkadot The requirements of .
The application case
Polkadot It is and will be the main network for deploying enterprise applications and high-value transactions that require bank level security and stability .
Kusama The initial use case was as a pre production environment , One “ The Canary network ”. For the average developer , This seems to be a testing network , What's the difference? ？ What exactly does Canary mean ？
Canary is a kind of bird ： in the past , Coal miners will put canaries in the coal mine , To measure the amount of toxic gas present .
Again , Canary testing is a way to verify Software , By offering to a limited number of users , Or maybe it's an isolated environment to release software , Without hurting people and birds .
stay Kusama A release on can be considered a canary release （Canary Releases）. These releases are usually phased . stay Kusama Early stage , The network is not only used for innovation and testing changes of parallel chain candidates , And still right Polkadot Proof of the concept of piecewise model .
In a typical blockchain development pipeline ,Kusama Will be located at “ Test net ” and “ Main network ” Between
As you can imagine , First, in the Kusama Build on , Can let the team in a real 、 Completely decentralized 、 Testing in a community controlled network , And Polkadot comparison , Lower risk of problems or errors .
Many projects will maintain parallel chains on both networks , stay Kusama Test and test new technologies and functions on , Deploy them to Polkadot.
Some teams will decide to stay only Kusama On , This may be where we see some exciting new technology experiments . Projects that require high throughput but not necessarily as secure as banks , For example, some games 、 Social networks and content distribution applications , Especially suitable for this use case .
Kusama It may also prove to be governance 、 incentive 、 Monetary policy and DAO（ Decentralized autonomous organization ） Ideal environment for ambitious new ideas and innovative experiments in fields such as .
Polkadot Runtime Future upgrades may also be in Polkadot The main network is deployed to Kusama.
In this way , We can not only see the introduction of these new technologies and functions Polkadot Previous performance under real-world conditions , And the teams already deployed to these two networks will also have an in-depth understanding of the performance of their own technologies under these upgrades .
Looking forward to the future
Final ,Kusama and Polkadot Will continue to exist as a separate network , They have their own communities 、 Own governance and own complementary use cases , Although they will continue to maintain a close relationship , Many teams may deploy applications on both networks .
future , We may also see Kusama Bridge received Polkadot To achieve interoperability across networks .Web3 The foundation continues to work on the development of these two networks , Provide important support and guidance to the team building the ecosystem .
