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.

Attestiv is a digital media validation company founded in 2018 to combat the rising threat of deepfakes and AI-generated content. Headquartered in Utah, the company provides solutions for businesses that rely on the authenticity of photos, videos, and documents, with a primary focus on the insurance, cybersecurity, and financial services industries.
The core of Attestiv's offering is its AI-powered platform that analyzes digital media to detect alterations, tampering, and generative AI content. The platform provides a "tamper score" to indicate the likelihood of manipulation and can identify specific anomalies through a forensic scan. This technology is delivered through a suite of products, including APIs and SDKs that can be integrated into existing workflows, as well as a user-friendly dashboard for manual analysis. Attestiv's solutions are designed to automate fraud detection, streamline processes like insurance claims and underwriting, and protect businesses from the reputational and financial risks associated with fake media.
Attestiv uses a distributed ledger to create a "digital fingerprint" that is recorded on the Hedera blockchain network. This allows for the immutable and verifiable timestamping of each asset, ensuring its authenticity can be validated at any point in the future.
Hedera Coinflip is a decentralized application (dApp) built on the Hedera network that offers a simple, "double or nothing" style betting game. Users can wager HBAR for a 50/50 chance to double their bet. The platform's core value proposition lies in its commitment to transparency and fairness, which is achieved through its unique use of the Hedera Consensus Service (HCS).
The fairness of each flip is guaranteed by a provably fair mechanism that prevents manipulation by either the player or the platform operator. When a user initiates a flip, a combination of a server-provided seed and a client-provided seed is submitted to the Hedera network via HCS. The immutable and unpredictable consensus timestamp assigned to this transaction by the decentralized network is then used to determine the outcome. Because this timestamp cannot be influenced or known in advance, the result of the coin flip is truly random and publicly verifiable.
A small percentage of each wager contributes to a progressive jackpot, which can be won by players who achieve a specific, consecutive number of wins. This jackpot serves as the platform's primary revenue model while also creating an exciting, high-reward target for dedicated players.

Acoer is an Atlanta-based technology firm founded in 2015 that specialises in developing blockchain-enabled software for the healthcare industry. The company's mission is to make health data more connected, usable, and secure by creating interoperable solutions that break down data silos and provide real-time insights.
Acoer's product suite includes the Health Data Explorer for analyzing medicolegal death investigation data, and HashLog, a data management and visualization tool. One of its key technologies is the Cryptographic Data Mesh, which creates a tamper-proof, auditable trail for data transactions. The company also developed RightsHash, a decentralised engine that uses NFTs to manage individual rights, such as patient consent for clinical trials.
Acoer's solutions are fundamentally integrated with the Hedera network. The company utilises the Hedera Consensus Service (HCS) to create immutable logs of data transactions, ensuring a verifiable "chain of custody" for sensitive health information. This allows Acoer to provide computational trust and cryptographic proof of data authenticity.
