The blockchain has a hybrid consensus mechanism, with elements of Proof-of-Existence (PoE), Proof-of-Process (PoP), and Proof-of-Audit (PoA).

The Band Protocol is a decentralized data curation protocol that aims to connect off-chain data with smart contracts. Band provides community-curated on-chain data feeds, and uses a system of incentives that ensures the data stays accurate. Developers can create applications with the Band protocol's infrastructure and then connect with any open API without needing to rely on a centralized party.
