2. INTRODUCTION
When blockchain technology took birth in 2009, the innovation had a viable promise to society, yet
limiting themselves to a small horizon in terms of applicability. The technology of blockchain
shimmered in and around the cryptocurrencies it introduced.
However, the industry application in blockchain was very limited and narrowed. But today, the
situation is different. Hardly there are industries that haven’t tasted the secret sauce of blockchain.
Industries like supply chain management, health, automobiles, defense, telecommunication, needless
to say even food industries have adopted blockchain technology to carry their industry operations and
have witnessed qualitative changes in their processes.
Document verification using blockchain technology is yet another generic that got recently
explored. Needless to say, this kind of document verification can enhance the authenticity and
integrity of the records, confidently establishing a label of trust on both - issuing authority and
claimers.

3. blocktick is one such application that helps you to ascertain the integrity of your records. The
medium helps institutions to generate, verify and issue professional certificates with much ease.
The institutions can establish a label of trust and reliability via offering tamper-free certificates to
the participants, be it the students or the employees.
The participants can thereby own a credible, cryptographically signed documents and can share
their credentials anytime to third-parties for further verifications.
In this world, where certificates are a marketing tool for the institutions and certificates, a living
proof of the participant’s earned credits, blockchain applications like blocktick can be of great
help to both institutions and its partakers.
The blockchain-powered system can help these institutions via providing a decentralized,
unalterable and secure information or asset storage to generate tamper-free records. Rather
depending largely on third-party providers, the institutions can independently store data,
generate certificates based on collected data and issue them confidently.

4. On the other hand, aluminis get all the benefits of having secure digital versions of their credentials,
which can be easily shared with their recruiters and other delegates. The partakers are also freed from
long-running waits of certificate-seeking, cost of issuance charged by authorities, much seen in
conventional zones.
The blocktick application can truly revolutionize the communication channels, enhance the efficiency
and transparency within the educational sector and job market via its feasible practice. With zero
dependencies on third party, no time-consuming processes, the blockchain assisted verification
process, simply enhances the issuing and verification of credentials. Be it the academic credentials or
professional certifications, blocktick helps in ensuring longevity and interoperability of your digital
records. The blockchain anchored document verification platform gives institutions the tool to
independently verify and issue credentials and other related documents. With blocktick, one can take
full advantage of the highest security and privacy levels of your digital records.

5. Also, blocktick is committed to self-sovereign identity of users, enabling user control of their claims via
easy-to-use verification portal. Without a single point of failure and a long span of time, blocktick
commits to verify and issue credentials in the most professional manner.
The document verification app contains components for issuing, viewing, and verifying certificates
across the blockchain. These components form all the parts needed for a complete ecosystem.
3 components of blocktick platform.
1. Issuing subsystem
a. A Linux based desktop application.
2. Verification subsystem
a. A verification server, written in node.js.
b. A web portal for verification.

6. 3. Blockchain subsystem
a. A highly efficient blocktick smart-contract in EOS blockchain.
b. Components which interconnect issue and verification subsystems.

7. Deliverables
1. A Linux based desktop application.
2. A web application in nodejs for verifying documents.
3. A complete portal for document management.
a. Admin portal.
b. User document management portal.
c. Verification portal.
d. Email templates.
4. An extendible XML schema

8. Workflow
In 3 simple steps you get your credentials verified and shareable.

9. Let’s dive deeper.
1. The blocktick’s issuing desktop application works on XML data. Making use of the highly
customizable XML schema, the user can export their batch of data from different sources, say
database or spreadsheet into the XML format.
2. Input the XML file to the Linux based desktop application. Within a few clicks, the desktop
application enables you to issue the documents into the blockchain. While showing the minimalistic
efforts to end-users, there are several processes that are performed in the background, which includes
a. Generating individual documents in JSON format from the input XML file.
b. Generating crypto elements out of these documents.
c. Signing and pushing a transaction on EOS blockchain, utilizing highly optimized blocktick smart-
contract embedded with crypto elements.

10. d. Updating each JSON document with this blockchain transaction details, so that each documents are
independently verifiable.
e. Storing updated JSON documents into the output folder with a folder name, which comes as the
batch name.
3. Upload these documents into your customized document management portal.
And finally, verify these documents from anywhere anytime by entering the document ID.
On each verification requests sent to the nodejs verification server, there are 5 efficient tests
performed to assure the document’s credibility.
1. Existence check - Check whether the issuance is recorded on the blockchain or not.
2. Integrity check - Check for any data manipulation.
3. Revoke status check - Check whether the document is revoked or not.

11. 4. Authenticity check - Check whether document issuer is genuine or not.
5. Validity check - Check whether the document is expired or not.
These tests are performed using the crypto elements recorded on each document with the help of
EOS blockchain. If any of the above tests fail, the verification process is put to stop and the specific
reason is shown to the users.
Not yet finished.
You can embed your document with a QR code so that simply scanning the document with your
smart-phone suffices your document verification process.
As per our policy, anyone can verify anyone’s document by simply entering document ID. This doesn’t
expose any document data to users. If the document verification succeeds, in the next step users can
proceed to view the document.

12. Users privacy is also taken care of blocktick. The application helps you in setting document visibility as
‘Everyone’ or ‘Privileged’ based on your preference. Our process flow makes super easy to manage
this. The users can seamlessly request their access for the document in case of necessity.
Share the documents that have a label of trust. The blocktick is an easy way to share your verified
credentials. Request demo to know more on the application
