Stellar Blockchain (XLM): Configuration Options

## Configuration Options

There are five main configuration options that are relevant as of now, and these are _Account Merge_, _Manage Data_, _Set Options - Home Domain_, _Set Options - Weight, Thresholds, and Signers_, and _SetFlags_.

### Account Merge

An _Account Merge_ operation is used when you want to delete an account on the Stellar blockchain. In order to delete an account, you must get rid of all your native XLM and subentries; such as trustlines, additional signers, open offers, and data entries.

### Manage Data

The _Manage Data_ operation consists of setting, modifying, or deleting data entries within an account’s metadata. Data entries are a key/value pair of application-specific data attached to an account. Each data entry increases the account’s minimum balance by one base reserve- 0.5 XLM.

### Set Options: Home Domain

The _Set Options_ operation enables many different configurations. The _Home Domain_ configuration option allows an individual account to point to a web browser domain. The domain serves a TOML file that displays information about the account's Stellar integration. The stellar.toml file proves who owns the HTTPS domain linked to a Stellar account, and that the owner is responsible for accounts and assets linked on it.

### Set Options - Weights, Thresholds, and Signers

Again, the _Set Options_ operation enables many different configurations. The weights, thresholds, and signers configuration options allows an account to set weights for the master key and additional signers, set thresholds for operations, and add additional signers to an account for multi-signature transactions. The weight of a signer determines how much leverage the signer has in each transaction, and the default weight for the master key is one. Each operation is categorized as having either a low, medium, or high threshold (0-255), and the default threshold value for each category is zero; which guarantees that the master key can always sign the transaction. If the thresholds are set to be greater than zero, then the master key's plus additional signers weights need to be greater than the operation threshold. It's possible to lock yourself out of your account if the operation thresholds are set to be greater than the signature weights added up together.

### Set Options: Set Flags; Set Trust Line Flags

Again, the _Set Options_ operation enables many different configurations. There are four flags that can be set: _Authorized Required_, _Authorization Revocable_, Authorization Immutable_, and _Clawback Enabled_. The authorized required flag will require another account to be approved before it can hold the issued asset. The authorization revocable flag will enable the issuing account to revoke another account from being authorized; which prevents the other account from transferring or trading the asset, and closes any open orders. The authorization immutable flag restricts any of the other flags from being set and disables the issuing account from being mergeable. The clawback enabled flag gives the issuing account the right to get back any portion of the other account's balance of the issued asset. When interacting with issued assets, it's important to know which flags they have set so you're not caught off guard by revoked or clawbacked assets.

The _Set Trust Line Flags_ operation enables the issuing account to set flags for individual trustlines. There are two flags that can be set for this operation: _Authorized_ and _Authorized To Maintain Liabilities_. The authorized flag gives full authorization to another account (truster) allowing it to transact freely with the issued asset. The authorized to maintain liabilities flag gives limited authorization allowing it to maintain current orders, but prevents future operations from occurring without approval.

## Outro

I plan on writing corresponding blog posts with relevant code examples. For now, I am simply learning the basics of the Stellar blockchain and utilizing the Stellar Laboratory in order to interact with the test net.
