boca ecology week observation parallel

◇ Polkadot From the Institute of ecology , It must be a boutique. ◇


Boca observes for a week , It's a sort out of what happened to the whole ecology of Boca last week , At the same time, we will share some of our observations on these events in the form of vernacular . This article aims to provide information and opinions , No endorsements for any project . Any item mentioned , No investment recommendation , Just for information .

1、 Observation and viewpoint

One 、 Why Boca is so late to go online Statemine?

Last week, , According to the plan , It should have been the first parallel chain Shell Will be upgraded to Statemine. however , It's too late to upgrade , You must be in a hurry . In fact, there was a little incident ,5 month 24 Japan ,Polkadot Nodes are due to blocks 5202216 Out of memory (OOM) Wrong and fail , The authorities have taken a little time to fix the problem . We need to understand the official , After all What Boca is doing now is more complex than all blockchains in the past , And no one has ever done . Poca spent 20-50 individual ( It depends on how to calculate ) It took three years for an expert developer to come to the version with full function parallel chain , And Ethereum's full functionality costs just Gavin and Jeff For a couple of weeks .

therefore , It's like building a small house with brick concrete structure before , Now we're going to build a building out of reinforced concrete , And it's the first time that a building has been built with reinforced concrete structure , therefore The difficulty is conceivable . On the other hand , We should look at Boca's current schedule with an inclusive attitude , Because what Boca is doing is something she's never done before , So for Boca , Every step must be taken with care , Naturally, the schedule is not as accurate as the time limit for building a house , Because in reality, building is a very mature technology , There are plans and methods in advance for how to solve the situation . But Boca is different , Its update iteration , Every step needs to go through the actual installation , Then observe if Boca is working properly , If it works well , Next update , Of course, this is an ideal state . But more often , There's a little bit of a problem running , Need to improve , And then see if it works , If there is a problem, adjust it , Until it works well .

therefore , Boca officials didn't mean to delay the pace , But out of rigor , We must have no problem before we launch the function , It's also for all those involved in Boca .

Last week was also the first anniversary of Boca's main network , It's still very young , Compared with other mature projects , Its rhythm is different , Still in the process of building momentum , One year after Ethereum was launched, it was still in its infancy , therefore , There's no need to worry . at present ,Shell The chain works well ,Shell Upgrade to Statemine It should be soon , Just be patient .

Two 、 Ethereal EVM With Boca WebAssembly It's not either

Last week, , The founder of Boca Gavin The doctor was invited to attend CoinDesk Of 2021 The consensus conference , He admitted that EVM In today's blockchain development status , But it also shows that EVM and WebAssembly It's not either , We should admit that EVM The historical position and role of the Chinese Communist Party , We have to explore the possibility of the next step , And this may be for him WebAssembly.

EVM full name ,The Ethereum Virtual Machine, That's the Ethereum virtual machine , It's part of the smart contract . And the current DeFi Most of the popular applications are around EVM To build smart contracts , therefore , Many emerging public chains , such as BSC,Heco,OKExChain,NEAR etc. , And by supporting EVM To attract Ethereum developers to their own Ecology .

however EVM It's not the best solution , It is itself Gavin A basic solution developed by doctor during his stay in Ethereum , There was no proper and mature solution at that time , You can only invent one yourself EVM. But now ,WebAssembly Technology has matured (WebAssembly It's a software format , abbreviation WASM), Some mainstream public chains also began to support WASM 了 ( such as EOS).WASM comparison EVM There are many advantages , Speed and efficiency have been significantly improved , Reduce or even eliminate precompiling , This can reduce gas cost , More languages will be supported , Comparable ratio EVM A broader toolset .

Even now EVM There are a lot of first mover advantages , But Ethereum also knows that EVM The shortcomings and WASM The advantages of , therefore , Ethereum will also be EVM Upgrade to eWASM( Ethereum version of WASM), So it seems , It's the Boca layout that comes first .

Boca's thinking is clear , Both admit that EVM Achievements , therefore , Technically compatible EVM Of ( After all, originally EVM It's also Gavin Invented ), But looking to the future , So Boca is more supportive of WASM technology .

If you put EVM and WASM Think of it as a traditional oil-burning car , And new energy vehicles with electricity , So Boca's goal is to be Tesla , But it's the same as hybrid cars right now . And in Boca Ecology ,Patract Open platform , It's for Boca WASM The parallel chain of smart contract ecology and DApp Development provides solutions , We're trying to make Boca better “ tesla ” Efforts .

therefore , For the whole blockchain, the trend will start from EVM go to WASM when , How to grasp the opportunity , You can pay more attention to Patract Trend of .

3、 ... and 、 Domestic mining is under pressure , Good PoS?

Since the vice premier proposed last week to crack down on bitcoin mining and trading , Domestic miners are fleeing , Or consider moving to storage mining . And last week some mining related bans and investigations were underway , I believe there will be rain and wind in the back , Will storage and mining be spared , That's a problem . On the other hand , As we mentioned earlier , China has a legal license in Hong Kong , Funds and exchanges that can operate cryptocurrencies , But now there is also a tendency to allow only qualified investors to participate in the investment , Maybe there will be something like Hong Kong stock investment , For example, the total amount of securities account and capital account cannot be lower than RMB 50 Ten thousand yuan , How to specify , It is not known if it will be carried out , But we can feel the domestic policy tendency , It's not allowing retail investors to participate , Reduce the financial impact of cryptocurrency , At the same time, in order to achieve the goal of carbon peak and carbon neutralization in China , Crackdown on power consuming bitcoin, etc PoW dig .

Is it not bright in the east , Bright in the West ,PoW It consumes a lot of energy , Basically no energy consumption PoS Would it be safer ? From the domestic policy tendency we just mentioned , Energy consumption , exactly PoS Will not be affected , for PoS It's good . But there's another level of tendency , In terms of reducing the financial impact , If the impact of cryptocurrency is still great , It is not ruled out that further detailed rules will be introduced in China , And it affects all cryptocurrencies , From this point of view PoS It's not immune . therefore , There are such expectations in , If there are further policies in the future , There's going to be more turbulence , We should make good psychological expectations .

Here are , Last week's introduction to Boca eco news , please Enjoy.

2、 Official news of Boca

An important announcement , We're starting to build groups !

Given the proliferation of ecological projects in Boca , But poor quality projects , Scam projects are all over the place , Be wary of , On the other hand, it is very difficult to understand the overall picture of the whole ecological development of Boca only in the group of Boca project parties , Missed a lot of opportunities .

therefore , We decided to build a Boca ecosystem , It's open to all the Boca eco projects , You can share your views on each project objectively , Understand the development of various projects in Boca , We can exchange information and seize opportunities together .

Official account “Polkadot Institute of Ecology ”, reply “ Into the group of ”, Add friends to the group .
