We’ve featured a few of NODE’s open source products here before, and they’re all focused on protecting your personal privacy and security. Because anonymity is part of the very nature of cryptocurrency, it’s imperative that you protect it—once your Bitcoin is gone, there’s no getting it back. All a ne’er-do-well needs is your public and private keys, and they can empty your account.
If you plan to access that account frequently, you may want to check out NODE’s other hot wallet offerings. But, if you want to let your cryptocurrency just sit there and increase in value, the new Icebox mixed technology cold wallet is ideal. A cold wallet is designed to store your account information — and therefore your funds — offline for long periods of time.
The “mixed technology” moniker applies because the Icebox can store your keys in a few different ways. The entire Icebox is contained within the kind of hard plastic case used for 1oz silver bars. Inside that case is a pair of 2KB NFC chips for storing your public key and your private key, and both of them are only connected to the antenna when the corresponding buttons are pushed, which means they’re inaccessible until then.
If NFC isn’t your style, there is also room for a micro SD card. You can store your keys on there, or other useful things like wallet software. Finally, there is room to simply leave a slip of paper inside with your keys written on it if you’re particularly suspicious of digital data storage. You can buy an Icebox from the NODE store for £10.50, or make one yourself from the open source files.
