HALO is a decentralized oracle solution that can provide a complete off-chain data solution for smart contracts on any underlying chain. It adopts the node ecological mechanism of quotation + dual-role verification. Any user can pledge HALO tokens with a low threshold to become a quotation node and obtain mining rewards. Institutional verification nodes audited by the HALO community and ordinary verification nodes with high thresholds can Provide ultimate security for the entire network in the authentication and arbitration links.

This mechanism takes into account the characteristics of decentralization and data defense.
