BTC Ηardware Wallets

BTC Hardware wallets are the most safe way to protect your bitcoins and better that online bitcoin wallets.
At internet you can find many companies that produce those wallets.

We have test some products of them and we want to recommend you the No1 company that builds solutions to bridge the physical world and the blockchain.
We talk about the Ledger. *
Ledger offers three families of products:

1. Personal Security Devices for end users, 
2. Hardware Security Modules for servers and 
3. Hardware Oracles for connected objects, machines and IoT.  

Technology.

Ledger’s core technology is a low footprint embedded Operating System built for Secure Elements and CPU enclaves. Thanks to its innovative asynchronous architecture, Ledger OS enables full orchestration of code and systems directly from the secure world.

The missing link.

Blockchain applications live in their own digital realm, totally orthogonal to the physical world. In order to exist and solve real life problems, they must interface with human operators or machines through atomic transactions and contract function calls. As much as a blockchain is intrinsically secure thanks to its consensus based mechanism, the global security architecture ultimately depends on the reliability of the inputs fed to the system. If transactions generation is compromised, or if a data source is corrupted, the whole security model collapses.
Ledger solves this major security issue by providing a trust layer between the IT system and the physical world: security devices to keep private keys out of reach of hackers and ensure a proof of presence of the user to mitigate man in the middle attacks, security modules for servers to enforce hard rules, and hardware oracles to measure and attest the existence of physical events (GPS location, vehicle speed, power consumption…).

Platform.

Blockchain Open Ledger Operating System (BOLOS) is an embedded secure OS powering Secure Elements (SE), Hardware Security Modules (HSM), CPU 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 (public, private...)

• 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.
  
  

  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.
  
  

  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.
