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.

Qples is a digital promotions platform that specializes in the creation, distribution, and validation of digital coupons for Consumer Packaged Goods (CPG) brands and retailers. The platform provides an end-to-end solution for delivering targeted offers to consumers through various channels, including mobile wallets and print-at-home formats.
It’s goal is to address long-standing challenges in the coupon industry, most notably fraud and the lack of real-time validation through its integration with the Hedera blockchain network. By leveraging the Hedera Consensus Service (HCS), Qples creates a verifiable and immutable record for each digital coupon it issues. When a coupon is created, its unique data is hashed and submitted to the Hedera public ledger, generating a "proof of state" with a secure, tamper-proof timestamp.
This on-chain verification allows for real-time authentication at the point of sale, effectively preventing fraudulent redemptions and unauthorized duplication through the creation of a universal, single-use digital asset. Its integration with the Hedera blockchain network enables Qples to offer brands a highly secure, transparent, and data-rich promotions solution.

By hashing these critical documents and recording them on the Hedera public ledger, Maalexi provides a high degree of security and transparency, which in turn helps to build trust between buyers and sellers.
Apache Log4j is an open-source, Java-based logging utility used by developers to record application events, errors, and operational data. It is a popular tool for debugging, system monitoring, and conducting audits across myriad Java platforms.
In the Hedera ecosystem, the log4j2-hedera repository offers a specific integration for Log4j 2.x and provides a custom appender that enables recording of logged events directly to the Hedera network via the Hedera Consensus Service (HCS). This allows applications to interact with HCS to submit their log entries, effectively writing them onto Hedera's distributed ledger.
The primary benefits of this integration include ensuring that logged data is distributed, secure, and transparent providing provable security. Furthermore, it guarantees the integrity and immutability of the recorded log information, as each entry is validated by Hedera’s consensus mechanism. This specialized appender provides a robust solution for applications requiring verifiable, tamper-resistant logging. This use case is distinct from how Hedera's core network software and provides additional verification.
