Hgraph.io is a network explorer and analytics platform for the Hedera Hashgraph public ledger. It provides a comprehensive interface to access, search, and analyze real-time and historical data generated on the Hedera network. This includes detailed information about transaction status, timestamps, involved accounts, and memos.

‍

The platform’s services apply to HBAR accounts and allows users to view balances, transaction histories, and associated Hedera Token Service (HTS) tokens or non-fungible tokens (NFTs) in real time. Hgraph.io also presents key network statistics, which can include overall transaction volume, the operational status of consensus nodes, details on HBAR supply, and usage metrics for Hedera network services such as the Hedera Consensus Service (HCS) and Hedera Smart Contract Service (HSC).

‍

Hgraph.io also serves as an HTS token explorer, providing data on total supply, distribution, and transfer activities. For developers and businesses it is a valuable tool for monitoring network activity, verifying transactions, and analyzing on-ledger events. It aims to enhance transparency and accessibility within the Hedera ecosystem by making ledger data easily navigable and understandable.

Chainlink is a decentralized oracle network connecting smart contracts on various blockchains with real-world data, events, and off-chain computation. Its fundamental purpose is to enable hybrid smart contracts by providing them with secure and reliable access to external resources, thereby bridging the gap between on-chain and off-chain environments. Chainlink is recognized as an industry standard for building, accessing, and selling oracle services.

‍

The platform offers a comprehensive suite of services to developers and enterprises. These include “Chainlink Price Feeds,” which deliver accurate and tamper-proof financial market data to DeFi applications, “Chainlink VRF” (verifiable random function) for generating provably fair randomness essential for NFTs and blockchain gaming, and “Chainlink Automation,” which provides decentralized and reliable smart contract automation. Furthermore, “Chainlink Functions” allow smart contracts to connect to any external API and run custom computations, while the cross-chain interoperability protocol (CCIP) facilitates secure data and token transfers across different blockchain networks. Chainlink Proof of Reserve offers automated verification of on-chain and off-chain reserves.

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.
