IBI, or Individual Bitcoin Interface, is a technology that issues human-readable payment identifiers for everyone. It works on top of the Bitcoin Lightning Network, a layer-2 solution for Bitcoin. IBI is built on open standards like LNURL and Boltcard, powered by Tiankii's state-of-the-art and enterprise-grade self-custodial infrastructure, and aligns with the peer-to-peer and eCash Bitcoin ethos.
