HashLog
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.

Inara World is a publishing platform that is working to create a new, tokenized economy for ebooks. Its focus is on solving the revenue and engagement challenges that authors face in the traditional publishing market.
The core of Inara's service is its "Streaming Ebooks" platform. This innovative model allows readers to pay for what they read, one page at a time, through a system of micropayments. This eliminates the need for readers to purchase an entire book upfront or to subscribe to a service. For authors, the platform provides a direct and transparent revenue stream, where they are paid for every page that is read.
The entire Inara World platform is built on the Hedera network. This integration is fundamental to the platform's ability to process a high volume of micropayments in a fast, secure, and cost-effective manner. By using Hedera, Inara provides a seamless and scalable solution for its tokenized ebook economy, creating a more equitable and engaging experience for both authors and readers.
