Network Configuration

In-depth explanations and articles concerning specific topics of interest.

📄️ Network Passphrases

Stellar’s Mainnet, Testnet, and Futurenet each have their own unique passphrase. These are used when validating signatures on a given transaction. If you sign a transaction for one network but submit it to another, it won’t be considered valid. By convention, the format of a passphrase is ‘[Network Name] ; [Month of Creation] [Year of Creation]’.

📄️ Federation

The Stellar federation protocol maps Stellar addresses to an email-like identifier that provides more information about a given user. It’s a way for Stellar client software to resolve email-like addresses such as name*yourdomain.com into account IDs like: GCCVPYFOHY7ZB7557JKENAX62LUAPLMGIWNZJAFV2MITK6T32V37KEJU. Federated addresses provide an easy way for users to share payment details by using a syntax that interoperates across different domains and providers.

📄️ Ledger Headers

Every ledger has a header that references the data in that ledger and the previous ledger. These references are cryptographic hashes of the content which behave like pointers in typical data structures but with added security guarantees. Think of a historical ledger chain as a linked list of ledger headers. Time flows forward from left to right, hashes point backwards in time, from right to left. Each hash in the chain links a ledger to its previous ledger, which authenticates the entire history of ledgers in its past:

📄️ Inflation

The inflation operation is deprecated. Here’s why:
