A user recently shared a link to a bitcoin forum discussing a simple and interesting HD wallet design. The user is seeking input on whether there are any flaws in the design or if it is safe for practical use. The design appears to use pure ECDSA and SHA-256, with a masterPublicKey generated from the masterPrivateKey multiplied by G. The masterChildPublicKey is derived from the masterPublicKey and a 256-bit nonce using SHA-256 and mod n. Similarly, the masterChildPrivateKey is derived from the masterPrivateKey and nonce using SHA-256 and mod n. Notably, all keys begin with a 02 prefix and the design allows for potentially unlimited custom derivation paths.
