P1: Goal and Problem statement

**Goal**: To use single cryptographic key pair to do transactions on multiple chains.
**Problem:**
Every day new blockchain coming up. In order to get services (by doing transactions, essentially) of these chains, a user has to manage their respective key-pairs which is becoming a hassle for them. The problem exists specially in an enterprise setting where an user (employee) has been using username and password for single sign on (SSO), and now one (or some) of the registered service provider (SPs) want to implement blockchain (same or different) in their ecosystem either for payment (on Bitcoin blockchain) or for smart contract execution, in either of the case, they require user to manage key-pair for doing transactions. Now the user has to manage set of key-pairs, since these SPs may or may not use same blockchain, apart from current username and password. User also has fear that tomorrow if another SP start using a different blockchain, then he has to manage another set of key-pair.
