What are RUFF Tokens

As an architecture combining block chain and internet of things (IoT), Ruff Chain includes a public chain for development as well as a distributed operating system. It extends the point-to-point network and consensus mechanism from the virtual to real world, and promotes the motion of atomic flow by information flow. RUFF Tokens, validated by virtual currency contracts, are placed in the Ruff Chain; they are the standards for incentivizing, consuming, and trading in the Ruff Chain community.

How RUFF Tokens are Used

  • Property or data exchange consumes virtual coins as they are settlement standard

  • Exchanges based on property right and device data generation can be settled with virtual coins

  • Any Ruff Chain based Smart Contract of Things can claim their virtual coins for settlements

  • IoT community provides node resources. Producers who contributes to the community will acquire RUFF tokens

  • RUFF Tokens is used to settle contract deployment and resource consumption

About Ruff Chain

IoT’s structure is essentially a network constitutes by multiple nodes. There are one or more applications in this network. All applications will interact with the chain through application interface while the computing power required by the local applications comes from edge computing units, could be gateways or routers. Applications can then manage the local network in a centralized or decentralized fashion and interacts with the chain.


  • Light Node (Executor)

    Interface for objects controlled by application
    After receiving authentication info through internet request, verifies and executes contract for the user, such as releasing the property right
    Cheap easy devices with no storing power can still undertake the light node job

  • Full Node (Recorder)

    Records info, event registration, and modification broadcast is voter and can change to representative node acted by devices with stronger capacities in the network PoW consensus algorithm was not used, so computing power requirement is relatively low Smart devices such as $200 HTPC, height router, NAS can all capable

  • Representative Node (Judge)

    The 105 nodes with most votes
    Must stick to the rules and responsible for packaging the blocks
    Once caught for malicious behavior, will be forgone by voters and loses the representative qualification
    Representative node can attain mining income through selling blocks

  • Control Node (SPV Wallet)

    Has certain computing power
    Can store headers for all blocks
    Can authenticate if designated exchange is registered on chain
    Can initiate an exchange using P2P protocol security
    Compared to the full node, no need to save and be online 24/7
