HALO is a decentralized oracle solution that can provide a complete data
solution for any smart contract on blockchain.
It adopts a node ecological mechanism of quotation and dual-role verification.
Any user can pledge HALO tokens with a low threshold to become a quotation
node and obtain mining rewards. The high-threshold ordinary verification
nodes and the institutional verification nodes which are appointed by the
HALO community can provide the ultimate security guarantee for the entire
network in the verification and arbitration process.
This mechanism takes into account both decentralization and anti-attack.
