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.

Ping Identity is an identity and access management (IAM) solutions firm that was founded in 2002. It offers a comprehensive suite of services that enable secure and seamless digital experiences for employees, customers, and partners.
The core of Ping Identity's offering is the PingOne Cloud Platform, an identity-as-a-service (IDaaS) solution that provides a wide range of capabilities, including single sign-on (SSO), multi-factor authentication (MFA), and API security. A key product within this platform is PingOne for Individuals, which leverages the ShoCard digital wallet to give users control over their own verified personal data.
Ping Identity uses the Hedera blockchain network to provide security and immutable record-keeping.. The PingOne for Individuals solution is built on the Hedera distributed ledger, which is used to ensure that all verified credentials are tamper-proof and that all transactions are securely recorded. By leveraging Hedera's high-throughput and low-cost infrastructure, Ping Identity provides a scalable and reliable platform for managing digital identities.
MetaStable is a decentralized finance (DeFi) platform that aims to provide a secure, private, and compliant environment for trading synthetic assets. The company is focused on leveraging advanced cryptographic techniques to solve some of the key challenges in the DeFi space, such as high slippage, impermanent loss, and regulatory uncertainty.
The core of MetaStable's service is its Automated Market Maker (AMM), which is designed to facilitate the trading of synthetic assets with minimal price impact. A key feature of the platform is its use of Zero-Knowledge Proofs (ZKPs), which allows for the verification of transactions without revealing the underlying data. This provides a high degree of privacy and confidentiality for users. The platform also includes a "DeFi Firewall," a proprietary technology that helps to ensure regulatory compliance by preventing illicit funds from entering the ecosystem.
MetaStable’s "chain-agnostic" design and support for EVM-compatible DLTs allows it be interoperable with various networks including the Hedera blockchain.
Edge is a US-based non-custodial cryptocurrency wallet provider that was founded in 2014. Its primary product, Edge Wallet, is a multi-asset mobile application that allows users to buy, sell, store, and trade a wide variety of cryptocurrencies.
Key services include in-app cryptocurrency purchases through various third-party providers, crypto-to-crypto swaps, and the ability to purchase gift cards with cryptocurrency. A distinguishing feature of Edge is its "zero-knowledge" security architecture, which means that the company has no access to user funds or data. The wallet uses a simple username and password system for account creation and backup, which is a more familiar experience for mainstream users compared to traditional seed phrases.
Edge has a direct integration with the Hedera network, providing full support for HBAR and other Hedera-based assets. This allows users to securely store and manage their HBAR within the Edge wallet. The integration is seamless, enabling users to easily send, receive, and trade HBAR alongside other major cryptocurrencies.
The Hyperledger Fabric plugin for Hedera Consensus Service (HCS) enables Hyperledger Fabric networks to utilize the Hedera public network for transaction ordering. This plugin allows developers to replace or augment traditional Fabric ordering services such as Raft or Kafka with HCS, leveraging Hedera's asynchronous Byzantine Fault Tolerant (aBFT) consensus mechanism.
The core function of the plugin is to have Fabric orderer nodes submit endorsed transactions to a designated topic on the Hedera Consensus Service. HCS then assigns these transactions a unique, immutable, and verifiable consensus timestamp and sequence. Fabric orderers subscribe to this topic via a Hedera mirror node, retrieve the ordered transactions, and use this sequence to consistently form blocks and propagate them within the private Fabric network.
By integrating HCS, Hyperledger Fabric applications gain several benefits including enhanced trust and decentralization in the ordering process, public verifiability of transaction sequences for increased auditability, and potentially reduced operational complexity compared to managing a traditional private ordering service.
