HALO is a decentralized oracle solution that provides comprehensive off-chain data solutions for smart contracts on any base chain. It employs a quote + dual-role verification node ecosystem mechanism, allowing any user to become a quoting node with low-threshold staking of HALO tokens and earn mining rewards. Institution verification nodes vetted by the HALO community and high-threshold regular verification nodes offer ultimate security assurance for the entire network during the verification and arbitration process.

This mechanism balances decentralization characteristics with data attack-resistance.
