Account System and Assets 💼

The XRP Ledger's account system forms the foundation of its functionality. Accounts are created when they receive their first XRP payment, with a minimum reserve requirement of 10 XRP to prevent spam. XRP Ledger addresses are derived from public keys, starting with 'r' and ranging from 25 to 35 characters.

🔑 Key Management

• Cryptographic key pair: public key (address) and private key (secret)
• Optional regular key pair for enhanced security
• Multi-signing capabilities

The XRPL supports two main types of assets:

1. XRP 💎
   • Native digital asset
   • Total supply: 100 billion XRP
   • Used for fees and as an anti-spam measure
   • No counterparty risk
2. Issued Currencies 💱
   • Represent value held by an issuer (similar to stablecoins)
   • Can represent fiat currencies, cryptocurrencies, commodities, etc.

Fees and Reserves 💰

The XRPL uses a system of fees and reserves to prevent spam and ensure network stability:

• Base transaction cost: 10 drops of XRP
• Fee escalation during high network load
• Account reserves: Base reserve (10 XRP) + Owner reserve (2 XRP per object)

Validators can vote to change fees and reserves, adapting to network conditions.
