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.

Hashlog is a data verification service that leverages the Hedera Consensus Service (HCS) to create immutable events or data logs. It enables applications and enterprises to submit messages to the HCS, where each message receives a consensus timestamp from the Hedera network, ensuring its integrity and order. This process provides a secure and transparent "proof-of-action" or "proof-of-event" capability.
Its core functionality offers a data trail for on-chain information. Once data is logged via Hashlog to the HCS, it cannot be altered or retrospectively tampered with, providing a high degree of data integrity. This is particularly useful for use cases requiring regulatory compliance, dispute resolution, or the tracking of critical operational processes. Developers integrate Hashlog systems using APIs or SDKs.
By utilizing Hedera, Hashlog provides decentralized trust, cryptographic verification, and public accessibility (if desired) for the logged information. Its applications span across multiple domains, including supply chain management for tracking goods, IoT data streams for device event verification, and legal tech for timestamping documents.
Headstarter is a decentralized fundraising platform and launchpad built exclusively for the Hedera network. Its primary purpose is to accelerate the growth of the Hedera ecosystem by providing a secure and streamlined environment for new projects to raise capital and build an initial community.
The platform operates on a tier-based system centered around its native token, $HST. To gain access to token sales, prospective investors are required to stake a certain amount of $HST, which places them into different tiers. These tiers determine the size of the allocation a user is guaranteed in an upcoming IDO, with higher amounts of staked tokens granting access to larger investment opportunities. This model creates utility and sustained demand for the $HST token while ensuring a fair and organized capital-raising process.
For projects, Headstarter provides an end-to-end solution for launching a token, handling the technical complexities of the sale and providing access to an engaged community from day one. For investors, it offers a vetted and secure venue to discover and support promising, early-stage Hedera-native projects.
MoonPay is a financial technology company that serves as a bridge between the traditional financial system and the Web3 economy. Its core business is providing a seamless and user-friendly payment infrastructure for buying and selling cryptocurrencies and NFTs. MoonPay offers both on-ramp services, allowing users to purchase digital assets with fiat currencies, and off-ramp services, enabling them to convert crypto back into traditional money. This is facilitated through a wide range of familiar payment methods, including credit/debit cards, bank transfers, Apple Pay, and Google Pay.
For businesses, MoonPay’s primary product is an embeddable widget that can be integrated directly into decentralized applications, wallets, and NFT marketplaces. This allows end-users to acquire digital assets at the point of use without having to leave the application, significantly simplifying the onboarding process and improving conversion rates for developers. The company handles all the complex backend processes, including payment processing and regulatory compliance such as know-your-customer and anti money laundering checks.
As a multi-chain platform, MoonPay supports a vast array of blockchain networks, including an official integration with Hedera. This partnership allows users to directly purchase HBAR, Hedera’s native cryptocurrency, making the ecosystem more accessible to a global audience.
Acoer is an Atlanta-based technology firm founded in 2015 that specialises in developing blockchain-enabled software for the healthcare industry. The company's mission is to make health data more connected, usable, and secure by creating interoperable solutions that break down data silos and provide real-time insights.
Acoer's product suite includes the Health Data Explorer for analyzing medicolegal death investigation data, and HashLog, a data management and visualization tool. One of its key technologies is the Cryptographic Data Mesh, which creates a tamper-proof, auditable trail for data transactions. The company also developed RightsHash, a decentralised engine that uses NFTs to manage individual rights, such as patient consent for clinical trials.
Acoer's solutions are fundamentally integrated with the Hedera network. The company utilises the Hedera Consensus Service (HCS) to create immutable logs of data transactions, ensuring a verifiable "chain of custody" for sensitive health information. This allows Acoer to provide computational trust and cryptographic proof of data authenticity.
