What is Dos Network

The vision is to offer standard and complete set of oracle services to all mainstream blockchains. Right now it's being built on Ethereum first, however, we're actively exploring and integrating with other blockchains like Thunder, Zilliqa, Neo, EOS, etc.

In the high level DOS Network consist of two parts: on-chain smart contract part and off-chain P2P network (client) part:

On-chain smart contract: A set of DOS system contracts are deployed on supported blockchains, including functionalities such as request handling and response/computation result verification, node registration and staking, group public key registration, stats monitoring, payment processing, etc. On-chain system contracts expose a universal interface to all user contracts across supported chains.

Off-chain P2P network: A P2P network consists of client software implementing the core protocol running by node operators. Client includes several important modules: event monitoring and chain adaptor module, VRF module, off-chain group consensus module, response parsing module, verifiable computation module, etc.
