# Core Concepts

{% hint style="info" %}
This section covers the core concepts you need to understand to build on 1Money, including accounts, token permissions, transactions, and more.
{% endhint %}

#### Account Model

On 1Money, all data is stored in what are referred to as "accounts”. The way data is organized on the 1Money network resembles a key-value store, where each entry in the database is called an "account".

Learn more about [**Accounts**](#account-model) here.

#### Token Permissions

1Money utilizes standard APIs for token and permission creation, with a structured permission model designed to optimize token economics and security.

Learn more about [**Token** **Permissions**](#token-permissions) here.

#### Transactions and Instructions

On 1Money, we send transactions to interact with the network. Transactions include one or more instructions, each representing a specific operation to be processed. The execution logic for instructions is stored on built-in programs deployed to the 1Money network, where each program defines its own set of instructions.
