**What is High Performance Blockchain (HPB)?**

High Performance Blockchain is the first permissionless public blockchain to innovate with hardware acceleration and provably random numbers:

* acceleration delivers fast, ultra low-fee, on-chain transactions

* provably random numbers support 100% fairness


HPB (the coin) is used to pay transaction gas fees and to reward node operators.

**How is this different from other blockchains?**

 High Performance Blockchain offers the following benefits:

* Provably random numbers: Generates on-chain, per-block, provably random numbers. A physical variable (tiny changes in voltage) makes these numbers impossible to predict.

* Hardware-accelerated: Faster than peers, thanks to the BOE accelerator card supplied to node operators, with a random number generator on board.
 
* High-throughput: Processes 5000 transactions per second, so suitable for DeFi, GameFi and NFTs.

* Secure: Hackers would have to compromise both code and distributed accelerator hardware.

* Supports smart contracts: Supports the contracts, code and tools preferred by Ethereum developers.

* Supports multiple languages: Software development kits in Java, JavaScript, Unity, .NET, Ruby and Python.

* Public: A permissionless blockchain with independent global node operators.

* High-performance: Proof of Performance (PoP) Consensus sends higher rewards to nodes with more  bandwidth, votes and staked HPB.

* Sustainable: PoP is much more energy-efficient than Proof of Work. The chain has been active since 2018.

* Community-driven: Moving towards a DAO structure. You can vote for nodes and community proposals.

**Where can I get HPB?**

HPB coin is available on both centralised and decentralised exchanges.

Roobee (ROOBEE) is a blockchain-based investment platform that allows users to invest in products from both the traditional and crypto markets. The platform is under active development and is already operational. Behind the platform is a team of developers who won prizes in hackathons, including the 2017 and 2019 ETHWaterloo hackathons held in Canada by ETHGlobal.

The mission of Roobee is to give any person with any level income an opportunity to invest starting just from $10 in investment products that are only available to big institutional players, qualified investors, millionaires, and funds. With the help of the Roobee platform, the goal is to empower people from all over the world to invest in any of the many investment products available on the platform: crypto, stocks, ETFs, IPOs, real estate, and more.

KardiaChain is a blockchain platform that aims to be fully interoperable and "non-invasive," meaning that blockchains can connect to the network without needing to make technical modifications to their own protocols. KardiaChain uses a dual-node structure to facilitate the connection between its own ledger and other blockchains, sharding for scalability and smart contracts for developers.

The platform relies on a native token, KAI, which is used for staking, transaction fees, participating in services and deploying smart contracts.

KardiaChain was first announced in October 2018, and its mainnet went live in December 2020.

CyberVein's big-data solution is based on the PISR (private, interlink, secure, robust) distributed database, database operations are stored on CyberVein blockchain network which runs on a Proof-of-Contribution (PoC) consensus mechanism. The solution is focusing on enterprise-level "blockchain + big-data" customized services.

CVT is the native utility token that is used for:

Storage payment: The data owner pays the corresponding storage fee based on the file size and bandwidth consumed in such a process.

Computing power payment: Payments from user to owner for usage, and remuneration for software developers is going to be exclusively conducted in CVT.

Data exchange: On CyberVein's federated learning platform, the data acquirer trades the data at a price contracted between the two parties for distributed modeling applications.

CROSS NFT issuance payment: Dapp businesses are obligated to pay for Storage and Data Exchange in light of network resources occupied, and may set up CyberVein token as a means of payment to issue NFT or conduct business in accordance to their desired business model.

CyberVein tools include:

PISR Consortium database, creates better data management: through safe and reliable virtual machine operation and maintenance of user data, data is efficiently aggregated for upstream data, and data traceability and tracking are realized to ensure the reliability of data sources and outputs, and achieve cross-level, cross-departmental data sharing to improve the timeliness, diversity, stock and density of data to realize the commercial value of data, and truly solve the problems in data flow.

DAG storage chain, creates safer data storage, with better efficiency, no block confirmation, low transaction fees, and also eliminates miner, supports asynchronous verification and parallel processing of each node, the more nodes, the faster the speed, the stronger the scalability, which leads to better scalability. The database backup on DAG storage chain provides an extra layer of security for businesses.

Cytrix, allows GPU to be shared. Nodes can contribute part of their GPU to the network, in return for compensation through the Proof of Contribution mechanism. The contributed GPU can aid enterprises or individuals in data modeling with federated learning.

Federated Learning Platform, enables data to be monetized. Federated Learning is a distributed machine learning workflow. The datasets are first trained locally, and the data of all parties is kept locally, without revealing privacy or violating regulations.  Individual terminals return trained models to the server to create a shared model. Effectively protect data privacy and security, solve the problem of information silo, and thus realize the value of data. The platform will also provide algorithms to support data modeling operations by enterprises and individuals.

Hive (HIVE) is a blockchain running on a delegated proof-of-stake (DPoS) consensus mechanism. It launched in March 2020 as a hard fork of the centralized Steem blockchain and as a gateway from Web 2.0 to Web 3.0. The blockchain claims to offer “lightning-fast processing times and fee-less transactions.” Examples of use cases include social media with monetized rewards for content creators, interactive blockchain games, identity management, micro-loans and more. The platform powers decentralized applications (dApps) like Splinterlands, PeakD and HiveBlog.

Hive is a social network of apps and services, where users discover the capacity of blockchain technology, connect to the platform and securely share content through equitable redistribution of value. Thus, the users are the proprietors of the network, and sponsors can contact communities and artists directly without intermediaries.

Hive is an open source blockchain that focuses on scaling through layer-2 sidechains, while still benefiting from a common layer-1 blockchain backbone to ensure distributed data integrity. The Hive ecosystem runs on two cryptocurrencies — the native governance token, HIVE and the USD-pegged HBD stablecoin.
