Chainlink is a decentralized oracle network connecting smart contracts on various blockchains with real-world data, events, and off-chain computation. Its fundamental purpose is to enable hybrid smart contracts by providing them with secure and reliable access to external resources, thereby bridging the gap between on-chain and off-chain environments. Chainlink is recognized as an industry standard for building, accessing, and selling oracle services.

‍

The platform offers a comprehensive suite of services to developers and enterprises. These include “Chainlink Price Feeds,” which deliver accurate and tamper-proof financial market data to DeFi applications, “Chainlink VRF” (verifiable random function) for generating provably fair randomness essential for NFTs and blockchain gaming, and “Chainlink Automation,” which provides decentralized and reliable smart contract automation. Furthermore, “Chainlink Functions” allow smart contracts to connect to any external API and run custom computations, while the cross-chain interoperability protocol (CCIP) facilitates secure data and token transfers across different blockchain networks. Chainlink Proof of Reserve offers automated verification of on-chain and off-chain reserves.

Tune.FM is a decentralized music streaming platform and NFT marketplace built on the Hedera network. It’s designed to upend and modernize the music industry's traditional compensation model. Its core mission is to enable transparent, secure, and instant artist payments while fostering direct connections with fan communities. 

‍

The Tune.FM platform is built on the Hedera blockchain network and utilizes the Hedera Token Service (HTS) for its native JAM token ($JAM), which relies on embedded Hedera features to facilitate real-time micropayments for artists, who are compensated for every second their music is streamed. 

‍

Tune.FM’s "play-to-earn" model features high speed processing with comparatively low fees, thus potentially allowing artists to retain a significantly greater portion of their earnings when compared to traditional streaming platforms.

‍

Beyond streaming, Tune.FM features an integrated NFT marketplace where artists can mint and sell digital music collectibles including songs, albums, artwork, and exclusive fan experiences such as backstage passes via JAM tokens. For listeners, Tune.FM offers a platform for new music discovery, direct artist interactions and support, and a way to earn JAM tokens through fan engagement.

The Hashgraph Tower is a real estate investment platform that democratizes access to property ownership through fractionalization and tokenization. Its aim is to allow anyone to invest in real estate projects from anywhere in the world, with a focus on environmental sustainability and transparency.

‍

The core of The Hashgraph Tower's service is its online platform, where investors can browse and purchase tokens representing a share in a specific real estate property. These "HTOWER" tokens provide investors with a claim to the monthly income generated by the property, as well as the potential to profit from the appreciation of the asset. The platform is designed to be a "hands-off" investment, with The Tower managing all aspects of the property and investment. Key features include a promised average profitability of 9%, no entry or exit fees, and the ability to resell tokens at any time.

‍

All investment projects are registered on the Hedera distributed ledger, which provides a transparent and immutable record of ownership and transactions. The platform utilizes smart contracts on the Hedera network to manage the investment process, from the initial funding of a project to the distribution of monthly income to token holders.
