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.

Twigital is a decentralized application (dApp) that enables users to create tokenized digital twins of physical objects. These digital twins are represented as 3D objects, which can be minted as non-fungible tokens (NFTs) on the Hedera network. The platform allows users to memorialize objects in the Web3 space.
The Twigital mobile application is available on iOS where it uses photogrammetry to capture real-world objects. Users can generate 3D models of objects from photographs. The app guides users through this process with detailed instructions and, once created, these 3D models can be minted as NFTs.
A key feature of Twigital is its integration with the Hedera network. Users connect their Hedera wallets to manage digital assets. This enables easy valuation, trading, and viewing of NFT details. The assets created are content-addressed using interplanetary file system(IPFS), providing unique identification for each digital twin. These unique twins can then be linked to minted NFTs. Twigital covers the transaction fees for creating these NFTs, which are factored into the cost of using the service.
