Logstash
Logstash is an open-source, server-side data processing pipeline from Elastic NV. It ingests data from multiple sources simultaneously, transforms it, and then sends it to a chosen destination. It is a core component of the Elastic Stack, often used for centralizing and processing logs, metrics, and other event data.
In the context of the Hedera blockchain network, Logstash can be integrated using tools such as the logstash-output-hedera plugin. This specific Java Output Plugin is designed for the Hedera Consensus Service (HCS). It enables Logstash to send processed events or logs directly to an HCS topic. Users configure the plugin by specifying details including their HCS topic ID, an operator account ID, and the associated private key for that operator account. An optional submit key used for topic creation can also be provided, along with the target Hedera network, which can be "mainnet" or "testnet".
By using this plugin, applications can leverage Logstash's data collection and transformation capabilities to then record events onto the Hedera public ledger via HCS. This creates an immutable, verifiable, and timestamped log of the data, enhancing transparency and auditability for any system employing this integration.

OneSpan is a Web3 platform that offers a dedicated eClosing solution designed to digitize and secure the entire lifecycle of high-value digital agreements, particularly in the mortgage and lending industries. The platform streamlines the closing process by enabling remote online notarization (RON), electronic signatures, and identity verification, all within a secure and compliant digital environment. A central component of this solution is the OneSpan eVault, a specialized repository for managing the authoritative copy of critical digital documents, such as promissory notes (eNotes).
To provide an unparalleled level of trust and auditability, OneSpan has integrated its platform with ProvenDB, a data integrity service built on the Hedera network. When a document is signed or a key milestone is reached in the eClosing process, a cryptographic fingerprint (hash) of the agreement is anchored to the Hedera public ledger. This action, facilitated by ProvenDB, creates a permanent and immutable timestamped record on the Hedera Consensus Service (HCS).

HiveTracks is a software company focused on providing digital tools and data-driven insights to beekeepers and supporting sustainable apiculture practices. It offers a comprehensive hive management platform through its web-based and mobile applications.
The HiveTracks platform enables beekeepers to meticulously record and monitor various aspects of their apiaries including colony health, inspections, treatments, feeding schedules, and honey harvests.
A significant aspect of HiveTracks' approach is its utilization of the Hedera Hashgraph distributed ledger technology (DLT). Leveraging the Hedera blockchain, HiveTracks enhances the integrity and traceability of beekeeping data by creating auditable records for hive health and establishing honey provenance. Furthermore, the Hedera integration enables beekeeper participation in emerging environmental markets such as carbon credits and data validation services.
HiveTracks specialized services empower beekeepers with robust data management capabilities while fostering a first-of-its-kind connected community. It also contributes to the overall health and longevity of bee populations and global climate health by promoting responsible and transparent beekeeping.
