NFT Grade
NFT Grade is a service that provides a standardized, objective grading system for non-fungible tokens (NFTs), aiming to bring greater transparency and trust to the digital collectibles market. The company's mission is to create a reliable method for assessing the value and rarity of NFTs, similar to how physical collectibles like trading cards are professionally graded.
The core of NFT Grade's service is its proprietary algorithm, which analyzes the metadata of an NFT to determine its rarity and overall grade. This process takes into account various factors, including the individual traits of the NFT and their prevalence within the entire collection. The platform provides a detailed "Grade Card" for each assessed NFT, which includes an overall score, a breakdown of its trait rarities, and a unique serial number. This allows collectors and investors to make more informed decisions by providing a clear and objective measure of an NFT's value.
NFT Grade utilizes Hedera's high-throughput and low-cost infrastructure to create a secure and transparent record of its grading process. Each Grade Card is minted as an NFT on the Hedera Token Service (HTS), creating an immutable and auditable record of the grade.

Siki is a Los Angeles-based company founded in 2021 that is building a multimedia and social platform centered around music and NFTs. The company's mission is to create a more sustainable entertainment ecosystem where artists and curators can directly monetize their work and engage with their communities in new ways.
The Siki platform combines several key services into a single social ecosystem. It functions as an NFT music streaming service, allowing artists to mint their songs as NFTs and earn higher royalties compared to traditional streaming platforms. It is also an NFT marketplace, where users can buy, sell, and auction these music NFTs. The platform is designed to be a social hub where users can connect with each other and their favorite artists, with features like tipping and live streaming integrated directly into the NFT experience.
The Hedera Token Service (HTS) is used by artists on the Siki platform to mint their music as NFTs. This allows for efficient and low-cost creation and transfer of these digital assets. By building on Hedera, Siki can provide a secure, scalable, and environmentally friendly platform for its users to stream, trade, and engage with music in a novel way.

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.
