DOS Network is a decentralized oracle service network that supports multiple chains. It provides solutions for Layer-2 networks that solve blockchain data acquisition and complex computing problems. The oracle service network provides real-world reliable data input and verifiable computing power for multiple chains. The DOS token is a utility token based on the Ethereum ERC20 standard, which can be used to motivate various participants in the system and ensure the growth and development of the ecosystem.

The problem the project solves

In addition to the widely discussed public chain performance issues, there are currently two major issues that hinder the implementation of smart contracts and large-scale commercial decentralized applications:

Blockchain is a closed deterministic system, which means that when the same smart contract code is executed, all verification nodes must reach an unanimous result, otherwise the consensus will be destroyed. This is an inherent and inherent limitation of blockchain consensus mechanisms. Therefore, the smart contract does not allow network I/O communication with the outside world, and the input of the smart contract can only come from the state and transaction data on the chain.
The resources allocated to smart contracts on the chain are very limited, such as the storage on the chain is very expensive, and the execution of smart contracts is limited (such as the block fuel limit of Ethereum, the CPU time limit of EOS, etc.). All of these hinder the birth of complex smart contract applications.
The mission and value of the DOS network is to solve the two problems mentioned above. As an infrastructure, it provides real-world data and more off-chain computing power for smart contracts and decentralized applications, and provides blockchain The landing of the chain and the large-scale application pave the way.
