Lets explore the Notary Platform Beta

Before moving forward please note that it is essential for both parties (Buyer & Seller) to be registered in application.

Deal will be initiated by seller. Buyer will be notified and will review the information and approve it, if every thing is correct. Contract fee 5 NTRY tokens will be charged from buyers account.

1) Log in to the application

2) Click on “profile” and fill out your data. You can also switch the picture with a click on the existing one.

3) When you slide the main menu to the left a screen with 3 tabs appears: Contacts, Purchased and Sold. Choose contacts and click “add contact”

4) Write the contacts name and click “search”. When you get a match please add it with the plus on the right side.

You can see that the contact was added successfully

5) Please go back to the main menu and choose “create contract”. Choose the contract party you want to sign a contract with. I have chosen Yumna.

6) Fill out the required data and click “create contract”

The message with contract information appears. Review the info and click “ok”.

Your contract is sent to buyer for approval. You can find it in ‘Sold’ tab with pending status.

7) At the same time, the buyer will receive the notification and contract will be added in his ‘Purchased’ list with the pending status. If the buyer approves then the status will be changed to ‘Enacted’.

8) After the status turns to “enacted” the contract is signed on the blockchain. You can find your contract on blockchain at Notary Platform Car Smart Contract. Please note the ID of your contract and visit this link: https://rinkeby.etherscan.io/address/0xd5a2378b5c7d2381a5f6fd1faaef47a736b757cd#readContract .

9) Enter your contract ID in row 4 (getDeal)

click on ‘Query’ button. You will find both buyer and seller address with hash of your contract data.

Smart contract includes important parameters of the contract which defines the deal. Defined are seller and buyer IDs as well the unique hash of the deal as immutable proofs on the Ethereum blockchain.

Conclusion

As you can see our current release of the app is a working prototype/Proof of Concept in which we have proved, that the merging of blockchain and a smartphone is possible and working.

Our goal in the next few months it to evolve the existing solution further and upgade it with more user friendly ways (signup process, design polishing and incorporation of some new technology).
