Starling Labs
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.

Circle's USD Coin (USDC), integrated with the Hedera network, offers a regulated, fiat-backed stablecoin pegged to the US dollar. This collaboration allows USDC to be minted natively on Hedera, leveraging the network's fast settlements (around 3-5 seconds), low transaction fees (typically $0.0001 to $0.001, paid in HBAR), and high scalability.
USDC on Hedera provides a trusted, stable, and reliable bridge for decentralized finance (DeFi) applications and end-users on the Circle and Hedera networks. Circle's increasingly popular suite of developer APIs offers full support for USDC on Hedera, facilitating its use in various applications including both payments and micropayments.
With USDC, enterprises and financial institutions have access to cross-platform liquidity and secure cross-border transactions. It’s currently used to facilitate payments and micropayments within applications such as Calaxy, Dropp, and Scintilla as well as to in support of numerous DeFi, NFT projects, and network bridge applications building on Hedera including SaucerSwap and Hashport.

EarthID is a UK-based company founded in 2018 that has developed a decentralised identity and verifiable credentials platform. The company's mission is to combat identity fraud, enhance data privacy, and build customer trust in an increasingly digital world.
The core of EarthID's service is a platform that enables organizations to issue and verify digital credentials in a secure and frictionless manner. This includes solutions for Digital KYC, which streamlines customer onboarding, and passwordless authentication, which enhances security by removing the need for traditional passwords. The platform is designed to be compliant with global data regulations including GDPR.
EarthID's platform is built on the Hedera network and uses the Hedera Consensus Service (HCS) to create an immutable and auditable log of all identity-related transactions, ensuring a high level of trust and transparency. The integration with Hedera is fundamental to EarthID's ability to offer a scalable and secure decentralised identity solution that can be used by organizations and individuals around the world.

Logstash is an open-source, server-side data processing pipeline from Elastic NV. It ingests data from multiple sources simultaneously, transforms it, and then sends it to a chosen destination. It is a core component of the Elastic Stack, often used for centralizing and processing logs, metrics, and other event data.
In the context of the Hedera blockchain network, Logstash can be integrated using tools such as the logstash-output-hedera plugin. This specific Java Output Plugin is designed for the Hedera Consensus Service (HCS). It enables Logstash to send processed events or logs directly to an HCS topic. Users configure the plugin by specifying details including their HCS topic ID, an operator account ID, and the associated private key for that operator account. An optional submit key used for topic creation can also be provided, along with the target Hedera network, which can be "mainnet" or "testnet".
By using this plugin, applications can leverage Logstash's data collection and transformation capabilities to then record events onto the Hedera public ledger via HCS. This creates an immutable, verifiable, and timestamped log of the data, enhancing transparency and auditability for any system employing this integration.
Pangolin is a community-driven, multichain decentralized exchange (DEX) that was initially launched in 2021. As a DEX, Pangolin facilitates the automated, peer-to-peer trading of digital assets through the use of smart contracts, eliminating the need for a central intermediary. The platform is designed to offer a user-friendly experience with fast settlement times and low transaction fees.
Pangolin's core service is providing a platform for token swaps, where users can trade a wide variety of digital assets. In addition to simple swaps, It offers a range of decentralized finance (DeFi) tools, including liquidity pools, yield farming, and staking for its native governance token, PNG.
Originally built on Avalanche, Pangolin has expanded to become a multichain DEX, with deployments on several networks, including a significant integration with Hedera. This integration allows Hedera users to access a robust and established DEX for trading HTS tokens and other digital assets within the Hedera ecosystem.
