FAQs of "relay chain" and "dot" in Poka ecosystem

“ 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 53 period , Relay chain is an important part of Boca heterogeneous Multi Chain Architecture , and DOT It also plays an important role in the network , Therefore, this issue will focus on the common problems of both .

Boca uses a relay chain Parallel chain “ Isomeric fragment multichain ” framework , Among them, the relay chain is also the central chain of Boca , It is responsible for the consensus of the whole network , At the same time, parallel chains connected to Boca relay chain share security .

actually , Relay chain mainly coordinates the whole system and parallel chain , Other work will be entrusted to parallel chains with different functions , Therefore, the operation efficiency of the network is greatly improved .

Besides ,DOT As the native digital asset of Boca, it also plays an important role in the whole network , Therefore, this issue of science popularization will focus on the relay chain and DOT Common problems of .

The trunk chain

What is the blocking time of the relay chain ？

Kusama And Boca network are currently based on every 6 It runs at the speed of one block per second .

This may change in the future . After optimization , It may be as low as two to three seconds , Or it may increase , In order to deal with the capacity of parallel chain network in real-time environment .

Does poca have a smart contract ？

No, —— Also have . Boca relay chain itself does not realize smart contract . The reason why there is no smart contract on the relay chain is part of Boca's design concept , It determines that the relay chain should be the minimum logic required to complete its work .

however , Boca will become a platform for other chains to realize smart contracts . Parallel chain can enable smart contract function , Then benefit from Boca's security and interoperability functions . Besides , The existing smart contract chain can be connected to Boca as a parallel chain or through a bridge .

Although Boca relay chain does not directly implement smart contracts , But there is no doubt that , There will be parallel chains doing this . So Poka ecosystem has a smart contract than “ Boca has a smart contract ” Better .

How to connect the external chain in the ecosystem ？

One of the blockchain interoperability technologies being studied and developed for deployment on Boca is the cross chain bridge . Bridges take many forms , The degree of trust associated with it is also different .

Poca mainly studies the model of trust minimization , This mode will bring economic costs to bridge operators , Therefore, it is economically safe . The bridge is being coordinated with other projects in the ecosystem .

Final , There will be a bridge between Boca and most other major chain stores .

DOT

DOT（ used ） New DOT What's the difference? ？

On Boca DOT（ used ） The unit is after the decimal point 12 position , Also known as 1e12 The Planck . stay 2020 year 8 month 21 Japan , Denomination date ,DOT（ used ） The value is revalued as 1e10（10000000000, or 100 Billion ） The Planck , That means new DOT The value of is ten decimal places . After repricing , new DOT be called DOT.

DOT What is the inflation rate of ？

The inflation rate is about 10%.

Part of the inflation is rewarded to verifiers to perform their duties , And the other part may be directly included in the national treasury . The specific percentages of the two are different , It's based on Staking Of DOT The amount depends .

Why can't we pledge all loans DOT？

Through the success of the parallel chain Crowdloan Contribute to the activity DOT, It is bound throughout the lease term . The lock-in period on Boca is two years .Crowdloan Of DOT Cannot be used for any other DOT Practical functions , for example Staking And democratic governance .

As a pair of DOT Lose Staking Reward or liquidity Exchange , Parallel chain teams may offer rewards to contributors .

Crowdloan DOT Provide rental funds for parallel chain slot auction . pledge DOT The purpose of is to reward / cut down （Slash） Mechanism to protect the network .

Allow for Crowdloan Of DOT Conduct Staking Will lead to complex consequences , For example Crowdloan Of DOT Conduct Slash, And these DOT Should have been bound throughout the lease term of the parallel chain .

In a way ,Crowdloan DOT Inaccessibility and lack of access throughout the lease period Staking Reward , Contributors are encouraged to support projects of value to the ecosystem .

At present, dozens of parallel chains have been launched on Boca relay chain , Heterogeneous Multi Chain interoperability is becoming a reality .

meanwhile , With the participation of more and more users , lock DOT The problem that leads to limited liquidity is also being solved , More and more projects have been launched around DOT The new product , Provide richer liquidity for locked assets , And more ways to get benefits .
