# Protocol

## Core <a href="#core" id="core"></a>

`Antelope Core` provides the basic building blocks for the `system` layer and because they are not implemented as smart contracts they do not provide the same level of flexibility. Nevertheless, the `core` implementation is also open source and thus it can be modified as well to suit custom business requirements.The core protocols are:

1. ​[Consensus Protocol](/infrablockchain-antelope/for-developers/overview/protocol/consensus-protocol.md)
2. ​[Transactions Protocol](/infrablockchain-antelope/for-developers/overview/protocol/transactions-protocol.md)
3. [Network Peer Protocol](/infrablockchain-antelope/for-developers/overview/protocol/network-peer-protocol.md)​
4. [Accounts & Permissions](/infrablockchain-antelope/for-developers/overview/protocol/accounts-and-permissions.md)

## System <a href="#system" id="system"></a>

The Antelope blockchain platform is unique in that the features and characteristics of the blockchain built on it are flexible, that is, they can be changed, or be modified completely to suit each business case requirement. Core blockchain features such as consensus, fee schedules, account creation and modification, token economics, block producer registration, voting, multi-sig, etc., are implemented inside smart contracts which are deployed on the blockchain built on the Antelope platform. These smart contracts are referred to as `system contracts` and the layer as the `Antelope system` layer, or simply `system` layer.&#x20;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.infrablockchain.net/infrablockchain-antelope/for-developers/overview/protocol.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
