content: HyperCash is a cryptocurrency designed to allow value transfer among blockchains and between blockchains and blockless cryptocurrencies. HyperCash supports private transactions, DAO governance, and quantum resistance. Overview HC is a cryptocurrency, similar to Bitcoin (BTC), with a strong focus on community input, open governance, and sustainable funding and development. It utilizes a hybrid “Proof-of-work system” and “proof-of-stake” mining system to ensure that a small group cannot dominate the flow of transactions or make changes to HC without the input of the community. A unit of Currency is called an ‘HC’ (HC). To ensure the integrity of the currency and prevent people from making fraudulent transactions or creating their own coins, HC uses a method of recórding transactions known as a blockchain. Hcash is the cryptocurrency of a distributed ledger that links block-based and blockless blockchain systems. HC create a new platform that can be connected to different blockchains (such as Bitcoin blockchain and Ethereum blockchain), thereby allowing value and information to circulate freely among systems, and redefining the value of blockchain . The HCASH network has two chains running laterally, with each serving different functions within the ecosystem. These two chains serve to provide us with an interlinked, bifocal dual-token, dual-chain ecosystem that will help us solve interconnection, privacy, and security issues prevalent in the current blockchain ecosystem. The HCASH ecosystem consists of two chains that include the HyperCash (HC) main chain and the HyperExchange (HX) chain which is derived from the main chain, but also work towards bridging communication between blockchains including BTC, ETH and others, and non-blockchains such as DAGs. HCash is Designed to facilitate the exchange of information between blockchains and non-blockchain networks. It is also a highly secure network, featuring quantum-resistant signature technology. Decentralized autonomous governance HCash is a community-driven autonomous governance model that can adequately fulfill the needs of the HCASH community, ensuring the efficiency of decision-making, and creating a more sustainable and inclusive development environment. PoW+PoS hybrid mechanism Under the hybrid Pow + PoS consensus mechanism, all PoW-generated blocks are verified by PoS miners in order to join the blockchain. Having both miners and stakeholders participating in block production eliminates the possibility of a hash power monopoly to a great extent while ensuring the security of the network. Privacy-Preserving Protocols HCASH implements post-quantum lattice RingCT protocols and improves and optimizes zk-snarks, providing clients who use HCash platform with more effective options for safeguarding users privacy in the future Post-quantum Signature Technology HCASH supports multiple post-quantum signature schemes, and is compatible with traditional ECDSA signatures, providing a high-level security protection scheme for users in a future quantum computing environment. HCASH Ecosystem The HCASH Ecosystem allows users to process complex cross-chain transactions and asset verification through Turing complete smart contracts in the HyperExchange chain, providing developers with support for DAPP development, laying the foundation for cross-chain distributed business applications. Hshare Hshare offers enormous technical potential in the industrial, private network sector. Multi-compatible and multifunctional software, which is already designed for quantum processors, makes it possible to combine a wide variety of crypto technologies. This offers advantages in the Fintech area, in finance, in dealing with Big Data, and also in the application area of the Internet of Things. Hshare seems to be not subject to any limitations. HyperCash Dual-token HyperCash and HyperExchange are the two core hubs of the HCASH parallel symbiotic-chain ecosystem. The tokens produced by HyperCash and HyperExchange are HC and HX, respectively. HC HC is the asset that will be distributed through the HyperCash chain and a 1:1 conversion ratio from HSR will take place (refer to the HCASH Foundation’s future official announcement regarding conversion details). HC is the value token that maintains the ecological stability of the HCASH network. HC can be used as an asset on the HyperCash chain to participate in the governance of the HyperCash chain, and can also be used as a pledged asset to participate in the production of HX tokens on the HyperExchange chain. HX HX is a functional token on the HyperExchange chain, its function will primarily be to maintain and invoke related functions within the HCASH ecosystem. HyperExchange HyperExchange is acting as one of the two core hubs of the HCASH parallel symbiotic-chain ecosystem, takes the lead in implementing inter-blockchain information interconnection by implementing a Blockchain Multi Tunnel (BMT) protocol, a HyperExchange Axis, Indicators, Smart Contracts, and more. HyperExchange is not only achieving cross-chain interconnection but will enable Turing-complete smart contracts, laying the foundation for complex distributed business applications.
