Introducing Ord Games, a protocol for creating game assets on the Bitcoin blockchain in just 3 minutes.

We are exploring a new concept of introducing games into Bitcoin: the Ord Games protocol. With its unique model and game design potential, Ord Games allows creators to directly forge game universes and items on the Bitcoin blockchain. Let’s dive in!

Introduction to Ord Games

Ord Games is a foundational protocol designed to define a Bitcoin game world consisting of individual players and loot. Game designers and developers can use this protocol to build unique, open-source, and decentralized games on the Bitcoin blockchain. Through Ord Games, game avatars, weapons, armor, and other basic game items can be forged in a completely decentralized manner.

The core of Ord Games is built on the “Ord Games protocol.” Each game world launched based on the protocol is defined through a “boot operation,” which includes parameters such as the game name, an avatar representing the game, and an array defining available loot and player types.

The boot operation serves as a unique identifier for each game world and can be referenced during item forging and player interaction. The structure of the boot operation typically follows the JSON5 format:

In the example above, GameName is the name of your game world, and GameAvatar is an optional image inscription used as a game icon. PlayerType and supply represent the categories and total count of each player type in the game. Similarly, class, name, power, and supply provide detailed information on the category, name, power level, and total supply of each loot.

Disclaimer: Blind Forging

One of the main drawbacks of this emerging protocol is the lack of reliable indexing services. This means that, in the early stages, the inscription process can only be done blindly. Users can only forge their items without any real-time inventory information. This means that users can easily waste gas by attempting to forge items that are already out of supply. It is strongly recommended to exercise extra caution during the inscription process until the indexing service is launched to track Ord Games inscriptions.

Example: Wizords Game World

Previously, we introduced the basic structure and concepts of Ord Games. Now let’s take a look at an example game world created on this protocol: Wizords.

Wizords is an on-chain battle game where you can forge wizards, orcs, and other mythical creatures, as well as assemble loot such as weapons, armor, and magical items. The “boot operation” for Wizords is as follows:

The gameplay involves players forging specific avatars and the best loot they can obtain. They assemble a “complete” player character for battle by placing the avatar and five pieces of loot into a Bitcoin wallet. This signals to the Wizords game client that they want to challenge other players.

Wizords also introduces the concept of “dual-key incarnation”, where players are defined by a unique private key and public key pair. The public key, visible to all players, is used to identify other players on the Bitcoin network. The private key, known only to the player, represents the player’s secret weapon.


Ord Games is a novel and exciting protocol that opens up a new world of gaming possibilities on the Bitcoin blockchain. Despite its experimental nature and associated risks, it offers a fresh approach to decentralized gaming and has the potential to disrupt the industry. If successful, it could become the protocol that brings games to Bitcoin!
