Hello guys, hope you all are doing well. Today I am writing home work task for professor @wahyunahrul which is about "P2P Messaging". Let's begin.

Please note that most of the images have been taken with other phone and so clarity may be the issue.

Give your opinion on the existence of Status on the current messaging app?

Status was introduced by Bennetts and Jarrad Hope in 2017 as a Blockchain based decentralised Peer to Peer messaging service . We are all aware of centralised messaging apps like Facebook, whatsApp, telegram etc and their working. These service are run by well known companies having absolute control over them. The episodes of hacking, data sharing without consent to the third parties and other security breech issues are not uncommon in centralised system. Owing to the shortcomings of centralised system and boom of technology in last decade, people have started moving towards more secure means of information / data sharing and blockchain technology has crucial role to play.

Status is empowered by blockchain as a P2P messaging service available as Android and IOS app for promoting wider accessibility. Unlike centralised apps, there is no centralised authority to monitor or access the content shared through Status. Moreover, if some tech savvy miscreants gain access to user account laterally, they can't read the shared content because the content shared via Status is ciphered once sent and is decoded only with the help of private key of recipient. Moreover, multiple serearvers are involved in keeping records so as to ensure security. Even the nodes or servers involved in maintaining records cannot read the shared content as they don't have access to private keys of users.

As for my opinion on Status is concerned, I would say that Status and such platforms represent future of social media platforms as for information sharing aspect is concerned. Such platforms are far superior than centralised counterparts in terms of security and privacy. As status is not only a messaging app, we shall explore its features in subsequent sections.

What is the message delivery mechanism used in Status? Give a complete explanation along with illustrations with pictures

The status app uses Blockchain based P2P and end to end message encryption mechanism of message delivery. Let's me explain, what that means.

In a centralised messaging platforms like Facebook, whatsApp users message their peers instantly but the message is recorded only on two servers involved in the message delivery to which the central authority has absolute access. It means that the two parties involved in messaging do not give their consent to third party but the owner company has absolute access to your private messages. Moreover, the hacking of these centralised social media platforms is not uncommon.

On status, the message is end to end encrypted which means that the message sent by one user is converted to a format that is non readable (encrypted) and the message can be read by reciever only after decryption to a readable format by making use of his/her private keys. As private keys are unique alphanumeric combinations that are not accessible to anyone other than a user of account, so it ensures secure message transmission. To avoid control by single authority, blockchain involves multiple nodes (servers) to store the message so that any attempt to alter the content of the message by any node is not replicated across other nodes and is declared as erroneous majority of other nodes. In this way, blockchain ensures highest degree of security.

In the above image, we can see that the message "Hello Alice" Is encrypted to non readable text which is decrypted at other end to the original text. The same ciphered text is distributed to all nodes involved in the networks.

What distinguishes the Key Cards offered by Status with Hardwallet in general? What's unique about it?

Keycards are hardware devices just like credit cards etc that are used to store private keys of status application in offline mode. We are aware of hardware key storage devices like Teezor, Keepkey etc . Keycard is similar device but the underlying technology is different. The NPC technology used in keycard doesn't require any intermediary to transfer keys from the card to the smartphone instead a user need to tap the keycard to the smartphone and keys are detected by application Itself to sign the transaction. A user is however free to enable PIN lock of the card and enter key everytime before performing transactions. This NPC based operation of Keepkey is unique and differentiates keepkey from other hardware devices.

Explore all the features in the Status application. (Screenshot required).

Status application is not just a messaging app. Just like a very famous centralised messaging application "WhatsApp" has adopted features like payment send/receive, Status has also adopted various other features to increase its use-case.

---

Wallet

---

It is analogous to payment sharing feature of whatsApp from chat field. Status being Ethereum blockchain based decentralised service, supports tokens matching ERC -20 and ERC-721 standards. Users are able to send and recive crypros with much ease and from chat field. Moreover, we can add other compatible wallets to the Status and operate from there. It means that, if we have funds on wallets other than that of native Status, wallet we can integrate that wallet with status and operate with ease.
