Cold Storage

Introduction

Cold storage is basically like a wallet, an offline wallet that is used for storing bitcoins. 

With regards to cold storage, the digital wallet is stored on a platform which is not connected to the internet, thereby protecting the wallet from any kind of unauthorized access and other such vulnerabilities that system which is connected to the internet is suspected of.

Importance of Cold Storage

  1. Prevents unauthorized access: Specifically, the private keys that actually control access to the crypto wallet, which makes sure that the platform can be an online platform hence prevents any unauthorized access.
  2. Protects from theft: Private keys which are stored on a wallet and are further connected to the internet are vulnerable to network-based theft. 

These wallets are known as ‘hot wallets. Cold storages on the other hand, resolves this issue by signing the transaction with the private keys in an offline environment. 

Any transaction which are generally initiated through online platforms are temporarily transferred to an offline wallet kept on a device such as a USB, CD, hard drive, paper, or offline computer.

Types of Cold Storage

Technically, any storage method that involves keeping your private keys offline would count as cold storage. This can range from any latest hi-tech solutions to the downright primitive, such as:

  • Writing down private keys on a paper.
  • Storing private keys on a USB.
  • Keeping the private keys on specialized offline wallet software built on a computer.
  • Using a dedicated hardware wallet built especially for offline storing.
  • crypto exchange with its own reserves in several protected and secured servers.
