\n\n**IMPORTANT NOTES ON MULTIPLE PRIZE ELIGIBILITY (Updated April 29, 2023):**\n\n- A project can win a maximum of either one (1) Track OR one (1) additional Bonus prize. This means a Project cannot win a Track prize and the Determination Prize or the Project Engagement prize.\n\n- A unique project can only win one (1) TRON DAO Forum Prize.\n\n- If there are no eligible submissions or participants for a prize, that prize will not be awarded.\n\n- Projects that won a prize in TRON Grand Hackathon Season 3 are NOT eligible to win prizes in Season 4. Entrants who submitted winning projects may submit and win with NEW projects or by submitting their existing project into the Builders Track and clearly stating their significant changes within the Hackathon time period.\n\n\n**A. Substitutions & Changes:** Prizes are non-transferable by the winner. Sponsor in its sole discretion has the right to make a prize substitution of equal value. Sponsor will not award a prize if there are no eligible submissions entered in the Hackathon, or if there are no eligible Entrants or submissions for a specific prize.\n\n**B. Verification Requirement:** THE AWARD OF A PRIZE TO A POTENTIAL WINNER IS SUBJECT TO VERIFICATION OF IDENTITY, QUALIFICATIONS AND ROLE OF THE POTENTIAL WINNER IN THE CREATION OF THE SUBMISSION. No submission or submitter shall be deemed a winning submission or winner until their post-competition prize affidavits have been completed and verified, even if prospective winners have been announced verbally or on the competition website. The final decision to designate a winner shall be made by the Sponsor and/or Administrator. It should be noted that all non-US based winners will be required to establish a verified account on Huobi, attain Level 3 status and provide their TRC20 USDD address from said platform in order to receive their prizes.

Prize Delivery:** Prizes will be payable to the Entrant, if an individual; to the Entrant’s Representative, if a Team; or to the Organization, if the Entrant is an Organization. It is the responsibility of the winning Entrant’s Representative to allocate the Prize among their Team or Organization’s participating members, as the Representative deems appropriate. Sponsor and Administrator disclaim any responsibility as to the distribution or allocation of the Prize amongst Team and Organization Entrants. A monetary Prize will be mailed to the winning Entrant’s address (if an individual) or the Representative’s address (if a Team or Organization), or sent electronically to the Entrant, Entrant’s Representative, or Organization’s bank account, only after receipt of the completed winner affidavit and other required forms (collectively the “Required Forms”), if applicable. Failure to provide correct information on the Required Forms, or other correct information required for the delivery of a Prize, may result in delayed Prize delivery, disqualification or the Entrant, or forfeiture of a Prize.

Additionally, it should be noted that non-US based winners will be required to provide a verified TRC20 USDD address from [Huobi](https://huobi.com/), attained by creating an individual account on the platform and reaching Level 3 status, in order to receive their prizes. US-based winners will only be required to provide their verified TRC20 USDD wallet address for prize disbursement.\n\n**D. Fees & Taxes:** Winners (and in the case of Team or Organization, all participating members) are responsible for any fees associated with receiving or using a prize, including but not limited to, wiring fees or currency exchange fees.

About TRON\n\nTRON is dedicated to accelerating the decentralization of the Internet via blockchain technology and decentralized applications (DApps). Founded in September 2017 by H.E. Justin Sun, the TRON network has continued to deliver impressive achievements since MainNet launch in May 2018.\n\nJuly 2018 also marked the acquisition and the ecosystem integration of BitTorrent, a pioneer in decentralized services boasting nearly 100M monthly active users. This would later on create the BitTorrent chain that bridges together ETH, BSC and TRON. https://bt.io/\n\nThe TRON network has gained incredible traction in recent years, with over 138 million users on the blockchain and upwards of 4.7 billion transactions.\n\nIn addition, TRON hosts one of the largest circulating supply of stablecoins across the globe, overtaking USDT on Ethereum in April 2021.\n\n# 7.

Whether it's coming across a wallet address or the owner of an NFT you found on a marketplace that you'd like to talk to. \n\nThat's where Yinbox comes in. We wanted to bridge that gap, and give people the ability to make connections with anyone on the blockchain. \n\n## About the Project\n\n**Message any wallet address on the blockchain.**\n\n

\n $\"\"$ \n

\n\nYinbox is the first fully integrated messenger app with end-to-end encryption on **TRON**, **NEAR Protocol** and **Ethereum**. Strike a conversation with anyone on with only their wallet address, **link NFTs** on the network, **send tokens** directly in conversations, and engage in a rich and intuitive messaging experience. Just connect your wallet and you're good to go, **no signups required**.\n\n## Features\n\n

\n $\"\"$ \n

\n\n**End-to-End Encryption**\n- Your messages are secured so only you and the person you're communicating with can read them. No one else in between can see your conversation, not even us at Yinbox.\n\n**Real Time Messaging**\n- Messages are sent and received in real time with no delays.\n\n**Direct Message & Private Groups**\n- Send direct messages to a wallet address, or create chat groups and invite multiple wallet addresses into a conversation.\n\n**Public Channels (Coming Soon)**\n- Create public channels that anyone on the internet can join.\n\n**Add-Ons**\n- Unlocks exciting features and blockchain integrations like linking any NFTs and sending tokens directly in conversations.\n\n## Business Model\n\n

\n $\"\"$ \n

\n\nWhile we strive to keep the majority of features free so anyone can experience and use Yinbox, we impose a small fee for additional usage in order to sustain the project's development.\n\nAfter exhausting free quotas, a small fee is imposed for each private group and public channels created. Direct messages are unlimitedly free.\n\n**Add-Ons**: In future development, we also want to open up our add-ons capabilities to enable other developers to build their own add-ons and monetize them. We are studying the model of this and are leaning towards commission based fees.\n\n## Technical Details\n\n### Architecture Overview\n\n

\n $\"\"$ \n

\n\nWe wanted to build a practical application with strong consideration for speed, security and convenience. After rounds of design reviews, we decided to go with a hybrid approach of leveraging both on-chain and off-chain services.\n\n#### Web Application & APIs\n\n- The frontend Web Application is developed in **React** using the **NextJS** framework. The authentication and core APIs are developed in NodeJS. We have plans to convert the core API to GraphQL to facilitate third-party integrations. These applications are hosted on Vercel.\n\n#### Real-Time Messaging\n\n- [Ably](https://ably.com/) service is used for maintaining an active connection to enable real-time message transmission in conversations.\n\n#### Blockchain Smart Contract\n\n- **TRON**: The Yinbox TRON Smart Contract is written in Solidity and is responsible for managing conversations creation, quotas and fee collections See [Smart Contract](#smart-contract) for details.\n\n#### Offchain Database\n\n- The offchain database is used to store the encrypted messages and various operations of the application. The database is hosted on MongoDB Atlas.\n\n### Process Flow\n\n

\n $\"\"$ \n

\n\n#### Connect Wallet\n- Users first connect to the chain they want using a wallet provider like TronLink, NearWallet or MetaMask. After connecting, user then signs a message to Yinbox Authentication API, which verifies the authenticity and returns a generated JWT token for access to Yinbox Core API calls.\n\n#### End-To-End Encryption \n- When starting a conversation, a session key is generated. This session key is unique for each conversation and is shared only with the participants of the conversation. This key is used to encrypt and decrypt messages on the user's browser.\n\n#### Conversation Activation\n- All conversations are created on the blockchain. The Yinbox Smart Contract manages the activation, fee collection and quota balances for each type of conversations: Direct Message, Private Groups and Public Channels.\n\n#### Message Transmission \n- All messages are encrypted on users browser using the conversation session key before they are sent across the network. They remain encrypted even on Yinbox and is only decrypted on the recipient browser.\n\n### Smart Contract\n\n| Function | Access | Description |\n|---------------|---------------|-----------------------------------------------------------------------------|\n| setOwner | Owner Write | Creates a listing of an NFT token making it available for receiving offers. |\n| setFee | Owner Write | Cancels a listing.
