Odyssey is primarily a decentralized sharing economy and peer-to-peer ecosystem, aiming to compete with and replace the likes of Airbnb and Uber. Odyssey dreams big - aiming to completely replace the concept of private ownership with an economy in which everything is shared and little is owned. It’s a long way from its goals, of course, but making peer-to-peer sharing more efficient with smart contracts is certainly a step in the right direction. The Odyssey website lists 9 advisors, with its primary two being Yi Shi, the CEO of Shanghai’s Avazu Holding, a leading global advertising platform, and Justin Sun, the backbone of the TRON cryptocurrency. The advisory team also includes Goh Jian Kai, founder and CEO of Southeast Asia’s cross-border payment solution system RateX. Odyssey has lofty goals, aiming to create a world where sharing is the norm and ownership or sharing monopoly doesn’t come in the way of people’s lives. A decentralized sharing platform where all service providers and customers are connected definitely sounds attractive. It’s a new currency, so it needs development to reach its goals. Of course, the fact that buying a large number of OCN tokens will not put a major dent in your pocket is a definite point in its favour.
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.
