Hello everyone my name is Clarence Liu
and I'm the VP of Development for
Elastos welcome to another video of the
Elastos 2020 anniversary series.
So you may have heard from me in the
last video speaking about BD and CR
Regions. Well just so you know this is the last
video I'll be doing in this 10 part
series so don't worry you'll be hearing
from the other team leads shortly.
The reason i'm speaking on the Elastos
Ethereum Sidechain is because i'm
also an advisor to the
Cyber Republic Ethereum Task Force and I sort of act as a go between between the
Elastos foundation core team
that builds the Ethereum sidechain and
the ETH Task Force that develops
tools and services
for the Elastos ETH Sidechain
So in this short video I'll be covering
what the Elastos ETH Sidechain is
roadmap and milestones as well as
adoption strategies we'll be using to
attract users and developers to Elastos.
So what is the Elastos ETH Sidechain?
The Elastos ETH Sidechain is one of the
most important sidechains of

Chinese: 
大家好，我是Clarence Liu，亦来云开发总监。
欢迎收看Elastos 2020周年系列的另一个视频。
上个视频中我讲BD和CR Regions，可能你已经听过。
这是本视频系列中我做的
最后一个视频，很快你们
就会看到来自其它团队的视频。
我一直兼任CR 以太坊冲锋小队的
技术顾问，可以说我是亦来云
以太坊侧链核心开发团队和CR以太坊冲锋小队的链接枢纽。
以太坊冲锋小队主要负责
开发以太坊侧链的工具和服务。 
工具和服务。 
在这段简短的视频中，
我将介绍亦来云以太坊侧链的
路线图和时间节点，以及
我们吸引用户和开发者的策略。
那么如何定义亦来云以太坊侧链呢？
亦来云以太坊侧链支持智能合约，

Chinese: 
是Elastos最重要的侧链之一。亦来云以太坊侧链基于
以太坊虚拟机（EVM)，与以太坊dApps完全兼容。
所以开发人员介入以太坊侧链非常容易，
大多数开发人员已经知道solidity，
也就是Ethereum智能合约语言。
我们的以太坊侧链主要有两个特别之处:
我们的DPoS节点是通过亦来云主链采用基于POW共识的ELA
币选出的。这是一个巨大的安全优势，
因为有一个独立的共识过程来掌控挖矿。
与其他DPoS区块链相比，
对于其他区块链，如果攻击者获得了对共识的部分控制，他们可能会
挖矿获得额外的ELA，
然后用ELA为自己投票，从而巩固他们对整个
系统的控制。在亦来云上
我们使用混合的AuxPoW(合并挖掘)跟比特币联合挖矿，
如果攻击者想挖矿造币并给自己投票，
他们得攻击比特币区块链，这样的话他们想控制共识是非常困难的。
我们另外一个特别之处是我们的以太坊

English: 
Elastos because this is what supports
smart contracts. Our sidechain is based on
the Ethereum Virtual Machine and is fully
compatible with Ethereum-based dApps.
This makes onboarding developers very
easy because most
developers do already know solidity
which is the Ethereum smart contract
language. Our Ethereum sidechain is
unique for two primary reasons:
Our DPoS pool is elected by our PoW chain's token ELA
from our mainchain. This is a massive
security advantage because a separate
consensus process controls minting. This is in
contrast to other DPoS blockchains where if an attacker
were to gain partial control
of the consensus they may be able to
mint extra tokens and then vote for
themselves with that token thus
solidifying their control over the
system. With Elastos because we use hybrid
AuxPoW (merge-mining) with Bitcoin
this is extremely difficult because the
attacker would have to also attack the
Bitcoin blockchain in order to
successfully mint and grant themselves more votes.
The other reason that we're unique is
our ETH Sidechain is going to be

Chinese: 
侧链将与亦来云其他服务完全对接。
开发人员可以无缝对接存储
和身份以及亦来云平台上的其他服务。
目前，dApp开发人员不得
不把各种服务和工具拼凑在一起，比如存储和身份等方面的服务。
比如存储和身份等方面的服务。如此下来，
dApp的开发就很怪，有各种不同的库，而且非常混乱，
因为每个库必须为每个服务跟踪不同的东西。
亦来云会竭力避免这种情况的发生。
因为我们的DIDs有非常好的接口和API，
我们有Hive存储，我们还有用于通信和elastOS应用的Carrier。
亦来云核心团队负责以太坊侧链的核心开发。
任何与以太坊侧链运行有关的东西，
如软件、基础设施、
维护都由他们来处理。
Cyber Republic资助了以太坊冲锋小队，
希望未来更多的社区成员能够组成团队
与EF核心团队一起努力，

English: 
fully integrated with our other services. And developers
will be able to access storage identity and
more in a seamless manner where
everything's all under one roof.
Currently dApp developers have to
piece together different services and
tools for things like storage and
identity,
resulting in a bit of a frankenstein
dApp with all sorts of different
libraries and
a large mess because they have to track
different things for each of these
services.
With Elastos we hope that won't be
the case because we have a
very good interface and API for DIDs, and
storage with Hive, and carrier for communication and elastOS applications as well.
The Elastos foundation core team is generally responsible for the core
primary development of the Ethereum sidechain
So anything that's intrinsic to the running of the
Ethereum sidechain such as the software
the infrastructure, the maintenance
is handled by them.
The Cyber Republic funded ETH Task
force and hopefully many more teams in
the future
is made of community members who work with EF to build non-essential

English: 
tooling and services for the
Elastos ETH sidechain.
So this include external services
that support DeFi like oracles or token
bridges that all help with user onboarding.
For our roadmap and milestones the Elastos core team and ETH Task Force will both work
hand in hand to ensure that all of our
work complements each other.
For the Elastos core team by end of
October we hope to have full DPoS
consensus done.
And then we also hope to have the EVM
version upgraded to Constantinople. Where currently it's on an older version
called Byzantium.
We also expect the elastOS team will
have full Ethereum support in their
application and wallet
as well as their plugins.
On the Ethereum Task Force side
one of our first priorities is building
ElaMask which is a browser extension
similar to Metamask that we'll be using
just for our ecosystem.
By the end of the year we are looking at improved block time
proposals that could improve the performance of the
Ethereum sidechain. We believe this is
paramount to maintaining our

Chinese: 
为以太坊侧链建立必要的工具和服务。
这包括支持DeFi的一些外部服务，比如oracle或者token bridges，
这些服务都有助于引入更多用户。
亦来云核心团队和以太坊冲锋小队将携手合作，
互相配合完成我们的路线图和时间节点，以确保我们所有的工作是互补的。
对于Elastos核心团队，我们希望10月底能在以太坊侧链上完成完整的DPoS共识。
我们还希望EVM
版本能够升级到Constantinople，现在版本是Byzantium。
我们还希望elastOS团队能够让elastOS应用、
钱包以及插件提供
完全的以太坊支持。
对于以太坊冲锋小队，
我们的首要任务之一是构建ElaMask，
这是一个类似于Metamask的浏览器扩展，仅限我们的生态系统中使用。
到今年年底，我们正在研究一个区块时间改良提案，
目的是提高亦来云以太坊侧链的性能。
我们相信，对于不断增长的以太坊世界，

English: 
competitiveness
in the growing Ethereum space.
We also expect on the ETH Task Force that by the end of 2020 we'll have the token bridges,
money markets and other DeFi basic
components ready to go.
Early next year on the ETH Task
Force we will be pushing for ETH
Sidechain security audits.
This is important to instill confidence
in outside investors to move their
assets to Elastos.
We also will be expecting that the
Elastos core team will continue to
fine-tune and ready a production launch
for the
Elastos (ETH) mainnet once everything is done as well as the security audits
this will be a new marketing push that
hopefully we can have early 2021.
As for DeFi one of our initial goals at
the ETH Task Force is to build a
small proof of concept which will allow CR proposal
funds to be collateralized and elaDai
to be withdrawn. So elaDai is a
stablecoin so it's perfectly fine for
proposers and
developers to spend that elaDai up
front.

Chinese: 
这些措施都对提高我们的竞争力至关重要。
我们预计，到2020年底，以太坊冲锋小队已经把token bridges、
货币市场和其他DeFi的核心组件准备就位。
明年年初，以太坊冲锋小队将推动以太坊侧链安全审计。 
这些会提高外部投资者对我们的信心，
推动他们把资产转移到亦来云
我们期待着核心团队继续进行微调。
等安全审计以及其它一切就绪之后，
团队能够完全准备好以太坊侧链的全面量产化。
这将是一个全新的市场推广，有望在2021年初实现。
至于DeFi，我们以太坊冲锋小队的初衷之一是建立一个
小型的概念证明，实现抵押CR提案
资金并支取elaDai。elaDai是一个
稳定币，无论对于提案人和开发者来说提前花费
elaDai都是没有问题的。

Chinese: 
只有项目完成并且生态系统的利益得到兑现时，
他们才会拿到剩余的资金。
这也是一个很棒的项目，
项目可以开源，而且它展示了DeFi的基本功能。
从项目布局角度，这个项目需要oracles和货币市场（money markets）等支撑，
这些都是我们要开发的。
另外，为了引入更多开发者使用
Elastos ETH sidechain，我们决定开发ElaMask的产品
ElaMask与Metamask相似，
只是它是为亦来云以太坊侧链量身定做的。
目前Metamask与亦来云以太坊侧链是可以兼容的。
但是，Metamask通常与Ethereum相关联，
当用户必须在Ethereum dApps
和Elastos dApps之间切换时，
它的UX(用户体验)非常差，
因为用户不得不在Metamask插件(扩展)中随时切换网络。
如有一个独立的ElaMask扩展，
那么Elastos dApps将自动打开ElaMask扩展而不是metamask扩展，
并自动连接到Elastos网络。对于用户来说，
这将是一个更加流畅的过程。

English: 
Only when they are complete and the
benefit to the last ecosystem is
realized do they receive the remainder
of the funds.
This is also a great project because it
can be open sourced and it will
demonstrate the basic functionality of DeFi, so
this scheme will require
things like oracles and money markets
which we'll all have to develop.
One of the primary ways we want to drive
adoption for the Elastos ETH
sidechain is to work on a product called
ElaMask.
ElaMask would be similar to Metamask
except it will be tailored for
the Elasto ETH network. Now
currently Metamask does work with
the Elastos ETH Sidechain but
Metamask is more commonly associated to Ethereum and also it's extremely poor
UX (User Experience)
because when users have to switch
between Ethereum dApps and Elastos
dApps they have to switch the
network in their Metamask plug-in (extension) which is extremely
jarring. By having a separate ElaMask
extension
Elastos dApps will automatically
open the ElaMask
extension instead of the metamask
extension and automatically connect to
the Elastos network. This will be a much
smoother

Chinese: 
此外，ElaMask还将支持ELA跨链转移，
允许新用户更容易获得ELAETHSC，
这相当于Ethereum侧链上的ETH，
也就是大多数dApps所需要的gas。
作为一个优质项目，我们认为Elastos
应该为dApp开发我们自己的产品，
这将提高我们在其他区块链社区的知名度和声誉。
为了引入更多开发者使用亦来云以太坊侧链，
我们还计划构建token bridges。
把我们的以太坊侧链和广泛的DeFi生态系统连接是势在必行的。
我们看到其他区块链产品也大量引入DeFi。
他们也在构建各种桥接。
以太坊冲锋小队将开发token bridge，
这个项目实际上是CR稳定币和货币市场项目的一部分。
我们必须考虑的另一件事是盈利农耕（yield farming）。
建了桥还是不够的。

English: 
interface for users. Also ElaMask will
support ELA cross chain transfers
allowing new users to more easily get
their hands
on ELAETHSC which is the equivalent of
ETH on our Ethereum side chain
which is used for gas for most of the
dApps.
Finally as a top-tier project we believe
that Elastos should create our own product
for dApp usage
this will improve our recognition image
and reputation
to the rest of the blockchain community.
Another way we want to drive adoption is
through building token bridges.
It's imperative to connect our Ethereum
sidechain to the wider DeFi ecosystem.
We're now seeing massive adoption by
other blockchain products to embrace DeFi
as well.
They're also all building bridges themselves.
The Elastos Ethereum Task
Force will work with on the token bridge
as part of a larger stablecoin and
money-market project
that is on Cyber Republic. Another thing we have to look at attracting is yield
farming.
Even if we build the bridges the bridges

English: 
are not worth anything unless we have
something on our side of the bridge, on
Elastos to attract the financial assets
to move over here.
The things that we can build on our side, in our ecosystem are things like
staking pools,
that allow you to earn a
return on investment on your
stablecoins. Cross-chain DEXs or
collateralized loan platforms that allow
users to borrow and lend money which
would be very cool,
if we can create a way for people to
earn reputation points through their
Elastos DID for example
and increase an Elastos type credit score
and borrow money from other people
for a set interest rate. The key here is
as long as the interest rates
for lenders is higher than other
blockchain projects we'll be able to
attract yield farming.

visit crregions.com where's the
dedicated page for DeFi.
So here's kind of a small road map
snapshot from
our website, we'll be updating this
regularly with the projects and
progress of the projects we're working

Chinese: 
我们在桥的这边需要有一些真正的东西，
比如成功吸引金融资产到亦来云平台。
在亦来云生态系统中我们自身需要做一些准备。
比如赌注池，可以让
用户或者投资者从投资中获得回报。
还有跨链DEXs或抵押贷款平台，允许用户借贷，
这都是很酷的，
如果我们能开辟一个路径，
比如让用户通过他们的Elastos DID来赚取声誉积分，
增加Elastos信用分数，并可以绑定固定利率贷款。
只要贷款机构的利率高于
其他区块链项目，
我们就能吸引盈利农耕（yield farming）。

Thanks for listening and as you can see
we are still a little bit of a ways off
from having a fully functional Ethereum
sidechain, but we expect to get there early 2021.
thank you

感谢您的收看。
要开发一个功能齐全的以太坊侧链，
我们还有一段路要走。但我们预计2021年初就能实现。
谢谢！
