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.

Identity Snap, developed by Tuum Technologies, is an open-source plugin that extends the functionality of MetaMask to include support for decentralized identifiers (DIDs) and verifiable credentials (VCs). This transforms MetaMask into a DID wallet, allowing users to manage their digital identities in a secure and self-sovereign manner.
The core of the Identity Snap service is its ability to create, manage, and verify DIDs and VCs directly within the MetaMask interface. It supports multiple DID methods, including did:pkh, did:key, and did:hedera, giving users a range of options for creating and controlling their digital identities. Key features include the ability to resolve DIDs to their corresponding DID documents, create and save VCs, and generate verifiable presentations (VPs) for sharing with other parties.
Identity Snap's did:hedera method allows users to anchor their digital identities on the Hedera public ledger, taking advantage of its high throughput, low fees, and robust security. The Hedera Consensus Service (HCS) is used to create a transparent and auditable record of all DID and VC events, ensuring the integrity and verifiability of the credentials.
Pyth Network is a first-party financial oracle network that supplies extremely low-latency real-world price data across crypto, equities, forex, commodities, and ETFs. In February 2024 the Pyth catalog of over 400 price feeds was launched on Hedera via a partnership with the HBAR Foundation, giving developers permission-less access to real-time data and confidence intervals to improve DeFi risk management. HLiquity, a decentralized borrowing protocol on Hedera, became the first application to integrate these feeds to ensure accurate pricing and proper collateralization.

Taskbar is a decentralized freelance marketplace and gig-economy platform built on the Hedera blockchain network. It connects clients with freelancers for on-demand tasks and services in a more efficient, transparent, and equitable Web3 environment. It acts as an alternative to traditional freelance websites by addressing issues such as high commission fees and slow payment settlements.
Taskbar facilitates payments in HBAR, USDC, and other Hedera-based tokens, enabling near-instant settlement directly to a freelancer's wallet. A key feature is its on-chain escrow system, where funds for a job are locked in a smart contract and released automatically upon successful completion of the task, ensuring security for both parties. It also boasts a gamified reputation system implemented to build trust and incentivize positive user behavior.
To enhance transparency and trust, Taskbar utilizes the Hedera Consensus Service (HCS) to create an immutable and auditable log of all critical platform activities, including task creation, proposals, and reviews. This forms the basis of a verifiable on-chain reputation system for freelancers.
