Karate Combat is a unique experience combining professional martial arts with gaming and Web3 technology. It features a full contact karate league with fighters from various karate styles and, occasionally, other striking-based martial arts, compete in a unique, 6.5m x 6.5m "combat pit" with 45-degree angled walls that promote continuous action.
A hallmark of Karate Combat is its innovative use of technology. Fights are streamed globally and feature immersive CGI environments created with the Unreal Engine, offering a visually distinct experience. The league is deeply integrated with Web3 technologies, and leverages the Hedera blockchain network.
This integration includes the $KARATE token, which allows fans to participate in the "Up Only Gaming" system which rewards users for wins without forcing them to wager tokens. Through a dedicated mobile app, fans vote for fighters, potentially increasing the fighters' prize pools, and earn more $KARATE tokens if their chosen fighters win, without losing tokens for incorrect picks.
Karate Combat’s unique combat system features rules emphasizing exciting, striking-based combat, with three-minute rounds and a scoring system that rewards aggression and effectiveness. It’s known for its fast-paced action, powerful knockouts, and unique presentation.

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.

Transak is a global Web3 payment provider that builds developer-focused tools to bridge traditional finance with digital assets. The company’s core service is to enable users to seamlessly buy and sell cryptocurrencies directly within any decentralized application (dApp). This is primarily achieved through a simple, embeddable widget or API that developers can integrate into their platforms with just a few lines of code.
By handling the complex backend processes of payment processing, fraud monitoring, and regulatory compliance like KYC/AML, Transak solves a critical onboarding challenge for the Web3 ecosystem. It eliminates the need for users to leave a dApp, register on a centralized exchange, and manually transfer funds, which significantly reduces friction and improves user conversion rates. The platform supports a wide array of local payment methods across more than 150 countries, including credit/debit cards, bank transfers, and other regional options.
Transak is integrated with the Hedera network. This enables developers building on Hedera to provide their users with a direct and localized on-ramp to purchase HBAR and other Hedera-based tokens.
