BPP (Bitcoin Payment Performance, Bit Light) is a fork based on the original Bitcoin chain. BPP shortens the transaction confirmation time by 15 seconds, reaching bank-level confirmation speed, which greatly improves the friendliness of blockchain technology for micropayments. BPP improves parallel processing capabilities through multi-channel expansion, can verify batch transactions at the same time, and adopts technology similar to zero-knowledge proof to achieve commercial-level payment privacy and confidentiality. BPP's technical strength is clearly ahead of similar competition in the market. BPP opens the prospect to a huge potential micropayment application in every dimension.
