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.

The InterWork Alliance (IWA) is an organization focused on simplifying and standardizing the use of token-powered services for businesses. As an initiative of the Global Blockchain Business Council (GBBC), the IWA works to create a common language and framework for tokenized assets, which allows different blockchain networks and applications to work together seamlessly.
The alliance's primary mission is to empower organizations to adopt and use token-based distributed services in their day-to-day operations. To achieve this, the IWA has developed several key frameworks, including the Token Taxonomy Framework (TTF), which provides a common set of definitions and standards for tokens of all types. The IWA also has a strong focus on sustainability, with task forces dedicated to creating standards for Voluntary Ecological Markets and Carbon Emission Tokens.
The Hedera network and its ecosystem partners are active members and contributors to the InterWork Alliance. Hedera has collaborated with the IWA on its Sustainability Working Group, and several applications built on Hedera are designed to be compliant with the IWA's standards.
