Ledger Nano S & Ledger Blue
Platform
Blockchain Open Ledger Operating System (BOLOS) is an embedded secure OS powering Secure Elements (SE), Hardware Security Modules (HSM), Secure Enclaves (Trusted Execution Environment -- TEE, Intel SGX). Contrary to legacy solutions such as Java Card or other industry OS, Ledger features an asynchronous architecture which enables a full orchestration of business code directly from the secure world. BOLOS is an unobtrusive framework allowing to run multiple applications all in isolations from each other, and build open source native code which will be portable from one secure platform to another.
AGNOSTIC
The Hardware Abstraction Layer (HAL) allows BOLOS to run on any kind of secure hardware. Thanks to the extensive crypto APIs, applications can leverage all types of blockchains (Bitcoin, Ethereum...)
SECURE
Isolation is natively provided by hardware mechanisms (each application can only access its own memory region, and operates in User mode, interacting with the Operating System running in Supervisor mode) or through a simple virtual CPU engine.
ASYNCHRONOUS
BOLOS breakthrough innovative architecture enables orchestration of embedded systems directly from the secure element. This enables proof of execution and origin, adding cryptographic attestation and integrity to critical data sources.
OPEN
All applications running on BOLOS can be Open Source and do not require any proprietary API. Native code (C) ensures maximum performance and flexibility.
I was checking out the ledger nano last week. I will probably get one in the near future, 🤞🏻When I have something really worth using it for.
Now I gotta dig into some of this ledger blue you speak of. Thanks for the info for a crypto newbie👍🏻👍🏻
