• Multisig added to HD Wallet
• Use the concept of an Oracle, originally coined by Alan Turing and adapted to Bitcoin by Mike Hearn. An Oracle in this context is a trusted third party that signs transactions only when certain conditions are met, in order to enforce security or implement other functions.
• HDM wallets with a third-party Oracle can provide security while not compromising usability. The user retains custody of 2 out of 3 keys, and does not experience counterparty risk, while still relying on a trustworthy third party to countersign normal transactions. The trusted third party, an Oracle, vets transactions to protect a user from theft, fraud and risk without being able to take possession or control of funds. The Oracle can also alert the user to wallet compromise and merchants with negative reputation.
