THORChain is a decentralised liquidity protocol that allows users to easily exchange cryptocurrency assets between different networks. The platform's native token is the RUNE, which is the base currency of the THORChain ecosystem and is an integral part of the platform's governance and security system, in that THORChain nodes must have at least 1 million RUNE to participate in consensus processes. The platform is not for profit. All fees generated by the protocol are paid directly to the users. THORChain was built using the Cosmos SDK and is powered by the Tendermint consensus mechanism. This makes the network secure against attacks, as a number of validators collaborate to validate and finalise transactions. In addition, THORChain's smart contracts are verified by several external security companies.
