HyperCash, the world's first post-quantum cryptographic digital currency based on bliss lattice signature. Services includes the development of main chain, browser, mobile wallet, RPC interface, OMNI protocol, voting system and so on.
Post-quantum cryptography
Post-quantum cryptography can resist the attack of quantum computers. HCASH integrates two most popular anti-quantum signature schemes, BLISS [DDLL13] and MSS/LMS [BDH11, 1LM95]. BLISS is the most efficient anti-quantum signature scheme at present. It has the smallest public key and the shortest signature size. MSS/LMS is the most efficient scheme based on hash signature.
The security assumption of MSS/LMS is very weak (that is, strong security). Its security only depends on the security of the underlying hash algorithm. Under this security assumption, MSS/LMS is provably secure.
Decentralized Autonomous Governance System
By deploying the voting and proposal system on the chain, the autonomy of the holder is greatly enhanced and the seamless transition from one set of rules to another is allowed. Decentralized decision-making and self-financing enable this model to build a strong and growing community without the influence of third parties.
PoW+PoS Hybrid Consensus Mechanism
In the field of public chain, a prominent contradiction has always been the contradiction between decentralization and performance. Block chains with PoWmechanism have done well in de-centralization consensus, but their performance is low and they can not support large-scale commercial applications.
The block chain with PoS mechanism will lead to over-centralization and over-centralization of power. PoW + PoS mixed consensus mining model can synthesize the advantages of both. Because we deployed the PoW + PoS mixed mining model.
Decentralized stake pool
HyperCash has built-in Stake pool function on the chain, which makes assets safer and profits more transparent. If the wallet is not running, it may cause users to miss the time when the ticket is added to the pool and when the ticket is voted as a ballot, so they can not get the opportunity of rights and interests reward. Therefore, if the wallet can not keep running 24 hours, the holder can choose to join the equity mine. Most of the mineral pools in the block chain are centralized, and there are risks of insecurity and opacity. One of the greatest benefits of decentralized pools is that users will not give control of tokens to the pool, and the pool is built in the underlying agreement, the rights and interests of the pool will be pre-determined in the agreement fees, but it can not obtain user assets, nor can it receive user incentives.
BLAKE256 algorithm
BLAKE256 is a very secure algorithm. Since its release in 2012, no effective attack against the algorithm has been found. As we all know, most block chain projects, including Bitcoin block chain, adopt SHA2 algorithm (SHA2 is a family of hash functions, including SHA256, SHA384 and SHA512, etc.). For example, Bitcoin uses SHA256 algorithm. SHA2 can be regarded as SHA1 with higher security factor, but it can not resist hash length extension attacks. It may have vulnerabilities. Compared with BLAKE256, SHA2 is obviously at a disadvantage in performance and speed. The BLAKE256 algorithm is deployed in HC main chain, which can ensure the security and efficiency of the system.
HCOMNI Protocol
HcOmni is a protocol layer for creating and trading custom digital assets and currencies. It is a software layer built on blockchain -- HyperCash. Omni transactions are HyperCash transactions that enable next-generation features on the HyperCash Blockchain. Our reference implementation, Omni Core is an enhanced HyperCash Core that provides all the features of HyperCash as well as advanced Omni Layer features.
Easily create custom currencies
With HcOmni it's simple to create tokens to represent custom currencies or assets and to transact these via the HC blockchain. The power and simplicity offered by HcOmni has helped to make it the leading HC based token protocol Blockchain
based crowdfunding
Decentralized crowdfunding is easy with HcOmni. Crowdsale participants can send hc coins or tokens directly to an issuer address and the Omni Layer automatically delivers the crowdfunded tokens to the sender in return - all without needing to trust a third party. HC implements and deploys the HCOMNI protocol layer, so that HC can also realize the functions of issuing tokens, crowdsourcing and so on.
