## ⚙️ Origins of Consensus: Federated Byzantine Agreement (FBA)

<mark style="color:$info;">In</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**2012**</mark><mark style="color:$info;">, the developers of the</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**XRP Ledger**</mark> <mark style="color:$info;"></mark><mark style="color:$info;">pioneered the</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**Federated Byzantine Agreement (FBA)**</mark> <mark style="color:$info;"></mark><mark style="color:$info;">— a consensus protocol:</mark>

* <mark style="color:$info;">Inspired by</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**Classical Consensus**</mark>
* <mark style="color:$info;">Based on</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**Byzantine Fault Tolerance (BFT)**</mark>
* <mark style="color:$info;">Enhanced with</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**modifications for performance and efficiency**</mark>

With **XRP** as the native digital asset, the main objective was to build a **faster, cheaper, and more sustainable Bitcoin** — enabling **peer-to-peer value transfer** at scale.

## 🔄 How the Consensus Protocol Works

<mark style="color:$info;">To uphold performance,</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**XRPL uses a consensus protocol**</mark><mark style="color:$info;">.</mark>\ <mark style="color:$info;">Designated servers called</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**validators**</mark><mark style="color:$info;">, which anyone can operate, come to an agreement on the</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**order and outcome of XRP transactions**</mark> <mark style="color:$info;"></mark><mark style="color:$info;">every</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**three to five seconds**</mark><mark style="color:$info;">.</mark>

<mark style="color:$info;">All servers in the network:</mark>

* <mark style="color:$info;">Process transactions according to the same rules</mark>
* <mark style="color:$info;">Confirm valid transactions</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**immediately**</mark>
* <mark style="color:$info;">Operate in a</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**public and transparent**</mark> <mark style="color:$info;"></mark><mark style="color:$info;">way</mark>
* <mark style="color:$info;">Rely on</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**strong cryptography**</mark> <mark style="color:$info;"></mark><mark style="color:$info;">to ensure system integrity</mark>

<mark style="color:$info;">📢 Currently,</mark> <mark style="color:$info;"></mark><mark style="color:$info;">**over 120 validators**</mark> <mark style="color:$info;"></mark><mark style="color:$info;">are active on the ledger, run by:</mark>

* <mark style="color:$info;">Universities</mark>
* <mark style="color:$info;">Exchanges</mark>
* <mark style="color:$info;">Businesses</mark>
* <mark style="color:$info;">Independent individuals</mark>

As the **validator pool grows**, the **consensus protocol ensures decentralization** of the blockchain over time.

{% tabs %}
{% tab title="In a nutshell" %}
The **XRP Ledger (XRPL)** is a:

* **Layer 1 blockchain**
* **Open-source**, **public**, and **decentralized**
* **Led by a global developer community**
  {% endtab %}

{% tab title="Extensive" %} <mark style="color:$info;">The XRP Ledger (XRPL) is an open-source, public, and decentralized Layer 1 blockchain led by a global developer community that pioneered DeFi by introducing the first DEX, tokenization of assets, smart contract features, and more.</mark>&#x20;
