# What is the blockchain?

**A blockchain** is a **digital, decentralized ledger** that records transactions across a network of computers. Each transaction is grouped into a **"block,"** which is linked to the previous block, forming a **secure and unchangeable chain**.

**How ebioro uses blockchain:**
* **Decentralized control:** Transactions happen without a central authority, giving you more control over your funds.
* **Transparency and security:** Every transaction is recorded on the **Stellar blockchain**, making it traceable and extremely secure.
* **Fast and low-cost transactions:** Using **Stellar**, ebioro can offer instant transfers with minimal fees.

**Blockchain** allows you to **send, receive, and manage digital assets like USDC safely and efficiently**, without depending on traditional banks.
