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 eftpos solution by Australian Payments Plus provides a cost effective, secure and flexible payment infrastructure for Australian businesses. It supports real time debit transactions, tap to pay on mobile devices, eftpos QR payments and least cost routing, which allows merchants to automatically direct debit transactions through the lowest cost network to help reduce the cost of acceptance.
Australian Payments Plus has worked with Google to enable least cost routing in Google Wallet, with ANZ and Suncorp the first issuers to offer this capability. It is also partnering with Giesecke and Devrient to develop eftpos Click to Pay with integrated least cost routing, an online checkout service that uses tokenisation to protect card credentials and is scheduled for rollout from early 2026 following pilot trials.
These developments enhance payment efficiency, improve security, support domestic data sovereignty and align with Reserve Bank of Australia findings that least cost routing can materially reduce merchant debit acceptance costs.
