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.

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.

Carbon Central, developed by Australian tech firm NoviQTech, is an enterprise-grade software platform designed to help large organizations manage the complexities of carbon accounting and environmental, social, and governance (ESG) reporting. The platform provides a unified, end-to-end solution for companies to measure, analyze, and report on their environmental footprint, particularly their Scope 1, 2, and 3 carbon emissions. It aims to replace disparate spreadsheets and manual data collection methods with a single, auditable system of record.
The platform is built on the Hedera network, leveraging its technology to bring a high level of integrity and trust to the ESG data management process. A key feature of Carbon Central is its use of the Hedera Consensus Service (HCS) to create an immutable and verifiable audit trail. As enterprises input emissions data, supplier information, and other critical ESG metrics into the platform, a cryptographic hash of that data is submitted to the Hedera public ledger. This process provides a tamper-proof timestamp and a transparent, auditable record that can be securely shared with and verified by regulators, investors, and other stakeholders.
EtaSwap is the first decentralized exchange (DEX) aggregator on the Hedera network. Its primary purpose is to consolidate liquidity from various decentralized exchanges within the Hedera ecosystem into a unified interface. This allows users to trade Hedera-based digital assets more efficiently, circumventing the need to navigate multiple platforms to find the best terms.
The platform functions by identifying the most advantageous prices and optimal trading routes across integrated DEXs for a given token swap. Key features include route optimization, direct integration with multiple Hedera DEXs, and a user-friendly interface designed to simplify the trading process. EtaSwap offers the potential for better execution rates and reduced slippage on their trades.
EtaSwap aggregates liquidity from prominent Hedera DEXs including SaucerSwap , Pangolin, HeliSwap, and HSuite. It serves as a single entry point for token swaps on Hedera, offering users seamless access to the combined liquidity of these platforms and is open to integrating additional exchanges.
Korbit is a South Korean cryptocurrency firm base in Seoul and launched in 2013. It was the first exchange to launch a Bitcoin-Korean Won (BTC/KRW) market.
