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.

Starling Lab for Data Integrity is an academic research center that operates at the intersection of cryptography, decentralized web protocols, and the humanities. A joint initiative between the USC Shoah Foundation and Stanford University's Department of Electrical Engineering, the lab's mission is to develop and prototype tools and principles to establish trust in digital records. In an era of rampant misinformation and AI-generated content, Starling Lab is pioneering new methods to securely capture, store, and verify digital media.
The core of their work is the Starling Framework for Data Integrity, a comprehensive, open-source methodology for authenticating digital content. This framework is built on three pillars: Capture, which involves creating a chain of custody from the moment a photo or video is taken, Store, which uses decentralized networks like IPFS and Filecoin to securely distribute and preserve content, and Verify, which leverages immutable ledgers to register and audit the provenance of digital assets. This end-to-end approach has been applied in various real-world scenarios, from documenting the 78 days of the 2020 U.S. presidential transition with Reuters to preserving the USC Shoah Foundation's archive of 55,000 holocaust testimonies.
Bitcarbon is a digital asset created by Diamond Standard, founded in 2018. Bitcarbon functions as the governance token for the "Carats" ecosystem, which is a system of commodity tokens backed by physical Diamond Standard Coins and Bars held in secure vaults.
The core product is a fungible and transparent diamond commodity, which is tokenised to create liquidity in the previously illiquid diamond market. Each "Carat" token represents a fractional ownership of a Diamond Standard commodity, providing a trustless store of wealth that can be used for payments. The Bitcarbon token, in turn, governs the Carats smart contract and earns revenue from the transaction and custody fees generated by the Carats ecosystem. This creates a unique digital asset that is intrinsically linked to the value and utility of a physical, real-world asset.
Bitcarbon and the entire Diamond Standard ecosystem are deeply integrated with the Hedera network. The company uses the Hedera Token Service (HTS) to mint and manage its digital assets, including the tokens that represent ownership of the physical diamond commodities.
HLiquity is a decentralized borrowing protocol built and deployed on the Hedera blockchain network. It offers users a method to take out loans against their HBAR collateral and enables HBAR holders to access liquidity in the form of a USD-pegged stablecoin without selling held HBAR assets.
The core mechanism allows users to deposit HBAR into a smart contract to mint the protocol's stablecoin to obtain interest-free loans with a one-time borrowing fee. HLiquity operates on a system of over-collateralization, requiring borrowers to maintain a collateral ratio above a specified minimum to secure their debt.
A key component of the protocol is the Stability Pool, where users can deposit the HLiquity-issued stablecoin. These deposits are used to absorb debt from liquidated positions, and Stability Pool providers are compensated with a share of the liquidated HBAR collateral. HLiquity aims to provide a capital-efficient and censorship-resistant borrowing solution within the Hedera DeFi ecosystem.
Buidler Labs is a software development and consulting company that specializes in building solutions on the Hedera network. It creates tools and infrastructure for developers to build and deploy decentralized applications (dApps) on Hedera, with a focus on enhancing the user experience and driving adoption of the ecosystem.
The firm's products include open-source libraries, hashgraph-react-wallets, and lightweight library that simplifies the process of connecting dApps to various Hedera-supported wallets such as Hashpack and Kabila. It also offers the Hedera Strato JS SDK, which provides a comprehensive toolkit for JavaScript developers. In addition to these developer-focused tools, Buidler Labs provides consulting services to help businesses design, build, and launch their own Hedera-based applications.
Buidler Labs’ work is aimed at lowering the barrier to entry for building on Hedera, particularly for developers who may be more familiar with Ethereum-based tools. Buidler Labs is a key player in expanding the developer base and the overall capabilities of the Hedera network.
