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.

Hyundai Motor Company has launched the Supplier CO₂ Emission Monitoring System (SCEMS)—an AI‑powered, blockchain‑based platform built on the energy‑efficient and highly scalable Hedera Network. SCEMS tracks carbon emissions across Hyundai’s entire supply chain, including raw material sourcing, manufacturing processes, and transportation, ensuring data integrity, transparency, and real‑time visibility.

By leveraging Hedera’s robust Distributed Ledger Technology, Hyundai securely collects and verifies environmental data, enabling accurate measurement, predictive forecasting, and compliance with emerging global emissions standards.
This solution simplifies and automates supplier reporting while strengthening stakeholder and investor confidence in the veracity of carbon data. Hyundai’s adoption of SCEMS exemplifies a real‑world enterprise use case within the Hedera ecosystem, demonstrating how sustainability-driven innovation can be powered by trusted, high‑performance DLT.

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.
