If you've been in cryptocurrencies for a while you already know about hardware wallet providers like Trezor, Keepkey and Ledger. If you haven't, using a hardware wallet is the safest means of storing your Bitcoins. Ledger has gone a step further and has released the world's first multi-currency crypto hardware wallet. The current firmware supports Ether (ETH), Ether Classic (ETC) and Bitcoin (BTC).





BOLOS (Blockchain Open Ledger Operating System)

BOLOS represents a major change compared to what the smartcard industry offers today — it puts developers in the driving seat, providing an unobtrusive framework to build source code portable native applications around a secure core, protecting the core against applications attacks, and isolating applications from each other without getting in the way (hence the french pun).
