1. VideoWiki
Online and immersive digitalization of Content, Curriculum, Coaching, and
Classroom.
Abstract: ​In the education system, more than 90% of students are impacted due to
school and university closures. Learning has been disrupted due to the pandemic.
There is a requirement for a new education model. The map is a depiction of countries
that are experiencing lockdown in terms of a countrywide or a localized lockdown. The
education sector is affected by these lockdowns. An estimate of 1.5 billion students
have been affected worldwide due to the pandemic.
Introduction : ​Inspiration Theoretical knowledge online is what most universities
have achieved, but practical training online so far seems unique. There is no such
platform which allows educators and students at the same time to create content and
collaborate on it to create a better educational model.
The theoretical form of learning may not be as efficient as ​practical learning​. Thus, the
effective means to enhance virtual teaching is the tool proposed in this plan. Based on
our survey, teachers are finding it hard to adapt to the digital means of teaching. The
requirement for a new education model has risen. The major problem is for the teachers
to convert their teaching material into ​digitized content​. Thus, the technicians in the
team are developing a simple tool that will assist the teachers. It will make the process
for conversion from normal text-based content into digitized content easier. The

2. teachers can develop and deliver classes through media platforms using this tool.
Currently, media platforms allow the addition of material for reference by the students.
Thus, the teachers would prefer the new platform which creates media files for them.
The children will benefit from the ideology of ​immersive and in-depth education​. The
new education model will ensure that the impact of the global virus pandemic is not too
severe in the education sector.
The solution is to tackle the situation by providing the teachers with an assisted course
creation tool to develop interactive media lessons for the students. This shift to virtual
learning enables students to learn through this digitized media anytime and at any
place. In this manner, the teachers, as well as students, can continue the education
from a place of safety and a protected environment of their homes.
We are building tools to auto-generate (convert) text-based content to video-based
online content with an extension towards gamification and immersive techniques for
advanced pieces of training.
We’ve created the version control on the Blockchain so that all the content can be
tracked along with their contributors so that they can be incentivized based on their
contribution.

3. Project Description : ​We offer a method for students to participate in applied
educational processes from their homes. Many technological mobile devices such as
computers and tablets are widely used in homes. These tools are effective for students
to be involved in applied training. For the K12 level or up to university students we build
video solutions, using simple AI techniques and some APIs available openly (list
available on request). We developed endpoints for these services for others to use and
innovate their own solutions.
The Blockchain ​Process flow begins with the user creating the content and uploading it
onto the VideoWiki platform.
The window variable recognizes if web3 is injected onto the browser or not.The content
developers need their metamask credential and address registered during the sign up.In
case, a viewer wants to create on top of existing content then he/she has an option to
register their metamask id so they can carry out developer operations. Once the user
clicks on to create a new video,the user is prompted to sign a transaction that generates
a node key. Once confirmed, it urges the user to sign another transaction to create a
repository. All these transactions are signed by the user through a Metamask popup
which comes on the screen once the button is clicked.
MetaMask pulls a neat trick by creating a JavaScript library that allows your normal web
browser to communicate with Ethereum nodes. Metamask is a cryptocurrency wallet
and a browser extension. This means that it works like a bridge between normal
browsers and the Ethereum blockchain. It lets you run the Decentralized Application
without being part of the Ethereum network as an ethereum node. Instead, it lets you
connect to another ethereum node called INFURA and run the smart contracts on that
node.Metamask also holds your public and private keys in the form of 12 seed words so
making it easier for the owner to access it and the extension is available for Chrome,
Firefox, or the new Brave browser. The interaction between Metamask and the user is
done through a JavaScript library called Web3.
This would redirect the user to the studio where the content is created.
Using AI-based text classification methods, we can identify the context of the content
and make queries to public video media libraries using APIs. These can be given back
to the teachers as an assisted course creation tool to develop interactive digital media
lessons for their students.

4. We offer a tool for teachers. They copy-paste the content they want to convert to a
video.
● The AI uses ​'sentence detection' algorithms to break the content into scenes
or Short or Long intervals (As selected by teacher), the grammar and
punctuation are checked by another AI process similar to the common
spell-checker.
● Then another AI algorithm detects the important keywords from each scene.
This tagging helps in identifying the context of the sentence/scene might be.
● Then we use the open media libraries to check stock videos around those tags
and fetch the relevant clips to present back to the teacher to pick. (Until here,
the only part the teacher/creator has done is paste the required content, rest all
is done automatically.)
● Now the teacher can review the suggested scene sequence, the overlaying
text and if everything is correct with prediction, then go ahead and stick the
videos together preview and publish.
● If the teacher wants to add narration, or change text, or change video scenes,
he would be able to do that and customize the course​.

5. Once published the node key is stored along with the video on the database.Now, new
developers can ​‘Fork’ ​these videos to break them apart and add new sections.After
finishing up their workspace,they have options to make a ‘​Merge Request’. ​After one
person’s request gets approved by the owner of the video, a notification is sent to all
other users that a request is approved to merge so they can wait till the latest version is
available or they continue to create their own repository apart from the parent
repository.
The user who was approved can now ‘​Merge’ ​his/her contribution and these changes of
versions and contribution details are stored on the ​blockchain​.
We will be maintaining a list of all editors using structures,we will map the addresses to
these structures to design ​access modifiers ,payment functions etc.
The list of contributors is maintained on the contract and can be further utilized in the
incentives system.

6. System Design and Testing :
The create contract has already been deployed from the side of VideoWiki. Users are
given access to this contract to create their node key. The second contract would be
used to create a repository structure. After the content creation the rest of the
blockchain functionality is done using the access control smart contract. The chain of
version control is first created in the two step flow of creating node key and repository.
The forking functionality and creation of a new branch apart from is a one step process
on the blockchain.
Incentivising Layer :
Token Creation, ICOs, Conducting Airdrops:
Using an ERC-20 complaint token for the platform which will be used for incentivization
on the VideoWiki platform.
The Ethereum blockchain allows you to create your own cryptocurrency, or token, that
can be purchased with Ether, the native cryptocurrency of the Ethereum blockchain.
ERC-20 is simply a standard that specifies how these tokens behave, so that they are
compatible with other platforms like cryptocurrency exchanges.
