Moonbeam Network builds cross chain DApp, provides a smart contract platform compatible with Ethereum, and can easily build local interoperability applications. It is supported by the Poka Polkadot network and developed by PureStoke. With Moonbeam smart contracts and compatibility with the Ethereum development toolset, bridge based integration can quickly build decentralized applications for use with users and assets on remote chains.Moonriver, as a decentralized smart contract platform, requires a River token to play a role. This tag is the core of Moonriver design and cannot be removed without sacrificing basic functionality.Some uses of River tokens on Moonriver include:Natural gas metering that supports smart contract execution;Encourage collaborators and provide motivation for creating a decentralized node infrastructure on which the platform can run;Promote governance mechanisms on the chain, including proposing a referendum, electing members of the Council, voting, etc;Pay transaction fees online.The economic behavior of supply and other tokens on Moonriver is the same as Moonbeam, but token allocation will be different to support the unique goals and attributes of the network. Moonriver will serve as Moonbeam's "canary net", but it is also a community led experiment, and the community will determine its development direction. Among other things, Moonriver will use a large parallel chain crowdfunding loan to obtain its initial parallel chain slot in Yayoi Kusama....
