Regarding the safety of storing mnemonic phrases in NOTE.SV, The query involves multiple sub-questions: Q1: Is the encryption secure? A1: Yes, we employ Electrum #ECIES, with a different set of encryption keys for every Create, Update, and Delete operation, ensuring robust security. Q2: Can mnemonic phrases be stored? A2: While possible, it’s not recommended. Encryption security doesn’t equate to user error immunity. Loss or leakage of the NOTE.SV mnemonic could lead to unauthorized access to notes, and if other wallet mnemonics are stored, the risk escalates. We advocate for traditional paper and physical safe methods for mnemonic storage. Q3: Can long-term storage be guaranteed? A3: This question seems directed at @Dr_CSWright . The longevity of #BSV’s stability, to run for a century, is uncertain; it hinges on the upkeep of its economic model and ecosystem. Anticipating this, we’re exploring multi-chain synchronization, including #RXD, #BCH, #IPFS, alongside local backup solutions. – at Nakano-ku, Tokyo
