+## Summary
+Contract module for simple authorization and access control mechanisms. 
+
+## Value Proposition 
+Contract module which provides a basic access control mechanism, where there is an account (an owner) that can be granted exclusive access to specific functions.
+
+## Motivation
+This module could be used through inheritance. It will make available the modifier `onlyOwner`, which can be aplied to your functions to restrict their use to the owner.
+
+## Non-Goals
+
+## Success Metrics
+
+## Description
+<!-- *  Summary of the context and proposed improvement. -->
+ 
+## Specification
+Based on Solidity implementation https://github.com/OpenZeppelin/openzeppelin-solidity/blob/master/contracts/ownership/Ownable.sol
+
+## Logic
+<!-- * Walk-through of the design and specification considerations, choices and approach. Provide practical examples of similar implementations, feedback from the community and perspectives on possible concerns. -->
+
+## Risks & Assumptions
+
+## Test Cases
+[Test cases reference implementation](https://github.com/protofire/AIP-011-Ownable/blob/master/src/test/java/com/altoros/aion/OwnableTest.java)
+## Implementations
+
+### Definitions
+[Reference implementation](https://github.com/protofire/AIP-011-Ownable/blob/master/src/main/java/com/altoros/aion/Ownable.java)
+
+### Methods
+
+**`getOwner` function**
+
+Returns the address of the current owner.
+
+> **returns:** Address of the owner
+
+``` java
+public static Address getOwner()
+```
+
+**`renounceOwnership` function**
+
+Leaves the contract without owner.  Can only be called by the current owner.
+
+> **Note:** Renouncing ownership will leave the contract without an owner,
+thereby removing any functionality that is only available to the owner.
+
+
+``` java
+public static void renounceOwnership()
+```
+
+**`transferOwnership` function**
+
+Transfers ownership of the contract to a new account (`newOwner`).
+Can only be called by the current owner.
+
+``` java
+public static void transferOwnership(Address newOwner)
+```
+> **parameters**  
+> `tokenHolder`: Address for which the balance is returned.
+
+
+**`onlyOwner` function**
+
+Stops transaction if called by any account other than the owner.
+Do not work for function calls
+
+``` java
+private static void onlyOwner()
+```
+
+
+**`OwnershipTransferred` event** <a id="revokedoperator"></a>
+
+Indicates ownership change form `oldOwner` address to `newOwner` address.
+
+> **parameters**  
+> `oldOwner`: Address of previous owner.  
+> `newOwner`: Address of new owner.
+
+``` java
+private static void emitOwnershipTransferredEvent(Address oldOwner, Address newOwner)
+```
