### How Bolt Works

Bolt integrates seamlessly with the Züs decentralized storage network, allowing you to monetize storage, stake tokens, and secure your crypto transactions with ease. Follow these simple steps to participate:

#### Step 1: Swap to ZCN

* Convert your ERC-20 tokens quickly and effortlessly to ZCN tokens directly through Bolt.

#### Step 2: Stake on a Blobber

* Choose a Blobber (storage provider) with available capacity, competitive pricing, and a strong quality rating.
* Staking your ZCN tokens earns you a share of the Blobber's storage earnings and additional crypto rewards.

#### Step 3: Transact Securely with Split-Key

* Secure your crypto using Bolt’s innovative air-gapped wallet and split-key authentication mechanism.
* Split-key authentication requires both your mobile and laptop, each holding separate cryptographic keys, ensuring maximum security during transactions.

### Bolt's Advanced Security: Split-Key Authentication

Bolt uses serverless, two-factor authentication called **split-key authentication**. This method involves two distinct keys stored separately—one key on your mobile device and another on your laptop.&#x20;

Both devices must cooperate to authenticate and sign transactions, significantly enhancing transaction security and preventing unauthorized access.

To further enhance security, Bolt recommends these best practices for key management:

**Cloud Backup (Encrypted):**

* Securely save your private key to the cloud with encryption.
* Additionally, store a physical copy securely offline.

**Secure Set-Up:**

* Generate cryptographic keys (`KEY1` and `KEY2`) on your mobile device.
* Transfer the second key (`KEY2`) to your laptop.
* Once your set-up is confirmed, securely delete the private key and the transferred `KEY2` from your mobile device, retaining only the essential keys for transaction authorization.

**Transaction Execution:**

* Transactions initiated from your mobile device (`KEY1`) must be approved separately on your laptop (`KEY2`), creating a robust security layer for every action on the blockchain.
