The Cosmos network consists of many independent, parallel blockchains, called zones, each powered by classical Byzantine fault-tolerant (BFT) consensus protocols like Tendermint (already used by platforms like ErisDB). Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub. The architecture is a more general application of the Bitcoin sidechains concept, using classic BFT and Proof-of-Stake algorithms, instead of Proof-of-Work.Cosmos can interoperate with multiple other applications and cryptocurrencies, something other blockchains can’t do well. By creating a new zone, you can plug any blockchain system into the Cosmos hub and pass tokens back and forth between those zones, without the need for an intermediary. While the Cosmos Hub is a multi-asset distributed ledger, there is a special native token called the atom. Atoms have three use cases: as a spam-prevention mechanism, as staking tokens, and as a voting mechanism in governance. As a spam prevention mechanism, Atoms are used to pay fees. The fee may be proportional to the amount of computation required by the transaction, similar to Ethereum’s concept of “gas”. Fee distribution is done in-protocol and a protocol specification is described here. As staking tokens, Atoms can be “bonded” in order to earn block rewards. The economic security of the Cosmos Hub is a function of the amount of Atoms staked. The more Atoms that are collateralized, the more “skin” there is at stake and the higher the cost of attacking the network. Thus, the more Atoms there are bonded, the greater the economic security of the network. Atom holders may govern the Cosmos Hub by voting on proposals with their staked Atoms.
QUBITICA is a community of more than 1000 developers, IT companies and investors from over 20 nations who want to work together to advance blockchain technology. This community has developed the QUBITICA infrastructure and since May 2018 it has been working on new projects under the associated brands and websites. Subcontracting is organized within the community. This requires the holding of QBIT, the paticipation shares in QUBITICA and all related projects. A long-term goal of QUBITICA is the development of project-related Smart Contract Solutions. These projects are treated as independent tasks and subprojects advertised individually. This allows us to achieve a flexible pipeline adapted to the needs of the market. The general developments in Blockchain will grow disproportionately, which is why it is the right time to find an intelligent solution to accomplish these tasks. What sets QUBITICA apart from an IT company operating in this field? QUBITICA is not an IT company, but an association of like-minded developers, IT companies and investors. IT projects will be handled under future brands and websites, and QUBITICA will be responsible for exchanging ideas, prioritizing projects and managing the shares in QUBITICA. QUBITICA's QBIT is an ERC-20 token that honors achievements. This honor is also comparable to shares. Developers receive QBIT for the implementation of projects and thus a share in the assets of the platform. A developer becomes, so to speak, a miner of shares through the power of his programming. He can now keep this QBIT, which represents his share of the overall project, or exchange it for Ether or USD / Euro. The mining of QBIT as part of the development of QUBITICA itself is no longer possible. This process is complete. QBIT is also the unit through which investors can acquire shares in the projects. To do this, buy QBIT either from the developers, any holder or via the platform. A purchase on exchanges is of course also possible. For new projects under other brands, the introduction of additional tokens is possible. QBIT holders automatically receive shares in this token upon issue.
