Blockchain for Energy (B4E) is a non-profit, member-led consortium dedicated to driving digital transformation within the energy sector. Comprising major energy companies including Chevron, ExxonMobil, and Repsol, B4E was established to collaboratively develop and implement blockchain-based solutions that can enhance efficiency, reduce costs, and increase transparency across the industry.
The consortium's flagship product is the B4ECarbon platform, an advanced digital measurement, reporting, and verification (dMRV) solution. This platform integrates AI and IoT with distributed ledger technology to provide a secure and auditable system for managing emissions data. It enables energy operators to track, report, and verify their environmental performance in near real-time, helping to prevent greenwashing and ensure compliance with global standards. The B4E Network & Platform, built on Hyperledger FireFly, serves as the foundational layer connecting all of the consortium's solutions in a decentralised environment governed by its members.
The B4ECarbon platform is built on the Hedera public network, and has been a member of the Hedera Governing Council since June 2025.

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.
