Hashlog is a data verification service that leverages the Hedera Consensus Service (HCS) to create immutable events or data logs. It enables applications and enterprises to submit messages to the HCS, where each message receives a consensus timestamp from the Hedera network, ensuring its integrity and order. This process provides a secure and transparent "proof-of-action" or "proof-of-event" capability.
Its core functionality offers a data trail for on-chain information. Once data is logged via Hashlog to the HCS, it cannot be altered or retrospectively tampered with, providing a high degree of data integrity. This is particularly useful for use cases requiring regulatory compliance, dispute resolution, or the tracking of critical operational processes. Developers integrate Hashlog systems using APIs or SDKs.
By utilizing Hedera, Hashlog provides decentralized trust, cryptographic verification, and public accessibility (if desired) for the logged information. Its applications span across multiple domains, including supply chain management for tracking goods, IoT data streams for device event verification, and legal tech for timestamping documents.

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.
MyHBARWallet is a free, open-source, and client-side interface that allows users to interact with the Hedera network. It was one of the first wallets to support HBAR, the native cryptocurrency of Hedera, and has played a significant role in the growth of the ecosystem.
Its core services is providing a user-friendly and secure wallet that allows users to create new Hedera accounts, generate and manage private keys, and send and receive HBAR and other tokens issued on the Hedera Token Service (HTS). It also supports staking, which allows users to earn rewards for helping to secure the network. A key feature of MyHBARWallet is its support for hardware wallets such as the Ledger Nano.
MyHBARWallet is a dedicated wallet for the Hedera ecosystem and utilizes all of Hedera's core services. It uses the Hedera Token Service (HTS) for all token-related functions, the Hedera Consensus Service (HCS) for any necessary transaction ordering and logging, and the Hedera File Service (HFS) for storing any relevant data. This deep integration with Hedera's fast, secure, and low-cost infrastructure makes MyHBARWallet a powerful and efficient tool for anyone looking to interact with the Hedera network.

SEALSQ is a Swiss-based semiconductor company that specialises in developing secure microcontrollers and implementing post-quantum cryptography. A subsidiary of WISeKey, SEALSQ provides the hardware foundation for securing connected devices in a wide array of industries, including smart energy, automotive, industrial automation, and consumer electronics.
SEALSQ’s product portfolio is centred on providing end-to-end digital security. This includes the VaultIC family of secure elements, which are tamper-resistant microcontrollers offering cryptographic services for authentication and data integrity. They also develop secure ARM platforms and are pioneering post-quantum RISC-V chips to protect against future threats from quantum computing. Beyond the chips themselves, SEALSQ provides Public Key Infrastructure (PKI) and provisioning services, allowing for the secure management of a device’s digital identity throughout its lifecycle.
SEALSQ is partnered with Hedera to integrate its quantum-resistant semiconductors directly into the Hedera network's infrastructure. This partnership aims to protect the Hedera ecosystem from the emerging threat of quantum computing by "future-proofing" digital signatures and communication channels. Specifically, SEALSQ's hardware will be used in the SEALCOIN project, a tokenised platform for machine-to-machine (M2M) transactions on Hedera, which is a core component of the DePIN (Decentralised Physical Infrastructure Network) being developed by WISeKey and its subsidiaries.
