BOB (Blok on Blok) is the world’s first modular smartphone powered by blockchain and developed by Pundi X, which is one of the largest decentralized cryptocurrency sales networks. The phone was showcased during the Consumer Electronics Show (CES) 2019 and is also the CES 2020 Innovation Award Honoree.
The company has an XWallet cryptocurrency service as well as an XPOS (point-of-sale) device for buying, selling, and accepting digital currencies. However, the BOB, previously called the XPhone, offers an entirely decentralized ecosystem for users to have absolute control over their data.
BOB runs on Function X OS, which is an open-source operating system. As it uses the blockchain ecosystem, every task on the phone, be it sending texts, making calls, browsing the web, and file sharing, all happen on a decentralized network, making it highly encrypted and thus secure. Each unit of the BOB is a node that supports the entire Function X blockchain system.
