Mobile numbers are a wide social graph and several dApps built on Ethereum and it's L2s can benefit by tapping into the infrastructure that standardizes the linkage of mobile numbers to people's wallets. From decentralized telephony to on-chain OTPs (verification codes), the opportunities that developers will uncover to deliver value-added services to participants of this infrastructure are massive. This will make it easier for the Ethereum dApps to onboard the Web2 and Web2.5 folks since they already have mobile numbers and don't need to learn or re-learn new behaviors. Further, we also provide users the option to acquire +999-prefix anonymous virtual mobile numbers, which can help them avail telephony benefits privately, as well as have an identifier that they can choose to share with whomever they wish to transact with. Their mobile number, current or virtual, won't be exposed on-chain, since we're using a salting and hashing mechanism to store hashed versions of this information on-chain.
