# Glossary

* **DAS**, a general user proxy for the entire Decentralized Account Systems project.
* **DAS account**, refers to each individual account, e.g. alice.bit, bob.bit.
* **DAS domain**, another name for a DAS account.
* **Registration**, refers to the process of obtaining a DAS account by paying a fee to the DAS contract.
* **Owner**, each account has an owner, who owns the DAS account and can modify the owner and administrator.
* **Manager**, each account has an manager, who owns the DAS account and can modify the account's parsed record.
* **Parsed Record**, every data associated with a DAS account, if a BTC address, a Twitter account, is called a parsed record.
* **Registration Fee**, there is a yearly fee for holding a DAS account, which varies for accounts with different character lengths.
* **Storage Fee**, each account's parsed record is stored on the blockchain and requires a fixed size storage space, so a storage fee is required. The storage fee will be refunded when the account is reclaimed.
* **Inviter**, any DAS account can be used as an inviter. You can get a certain discount when you fill in an exisiting DAS account as an inviter when you register your account; others can also get a certain bonus when they fill in your DAS account as an inviter when they register their account.
* **Channel**, any product that integrates a DAS registration service (such as a wallet) can be called a channel. If a user completes a registration through a channel, the channel can receive a percentage of the registration fee.
* **Registrar**, an organization/individual that provides a registration interface and payment method for users.
* **On-chain time**, the time on the blockchain, which usually lags slightly behind real world time and does not pass as evenly as real world time.
