Chainlink
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.

Turtle Moon is a Web3 software development and solutions company that functions as a core infrastructure builder for the Hedera ecosystem. It focuses on creating open-source tools, services, and standards that empower developers and accelerate the growth of decentralized applications on the Hedera network.
One of Turtle Moon's most significant contributions is the creation of the HCS-20 standard, a framework for issuing and managing fungible tokens using the Hedera Consensus Service (HCS). This standard provided an efficient, low-cost alternative to smart contracts for tokenization. They have also developed and open-sourced a suite of "Turtle Moon Tools" for NFT minting and management, making it easier for creators to launch projects on the network.
Beyond infrastructure, Turtle Moon is an active participant in the Hedera community, closely associated with leading the technical development for projects like HGraph Punks.
