币界网报道：According to the news on June 27, Charles Guillemet, chief technology officer of Ledger, said on the X platform that the current 320kb memory of Nano S is difficult to support new applications, feature submissions and updates. LedgerOS, Bitcoin, Ethereum and exchange applications alone almost fill up the memory, resulting in the inability to support new features and security enhancements such as multi-application parallelism, clear signature improvements, transaction checks and Ledger Sync™, exchange (such as interaction with THORChain, etc.), device language packages, etc. In complex encryption environments, these features are critical to improving clarity, usability and security, and require stronger hardware support. Guillemet emphasized that if the existing Nano S users have normal devices and the mnemonics have been backed up, their assets will remain safe and accessible, and the basic operations (sending/receiving/transactions) of mainstream currencies such as BTC/ETH will not be affected. However, upgrading to a new device can obtain more comprehensive application support, future new features and the best security experience. Earlier yesterday, news that Ledger is about to phase out Nano S has caused dissatisfaction among users and has been questioned for forcing users to buy new devices.
