This past Sunday, after months of hard work, Galileo-3, the Andromeda Chain went live on testnet. The blockchain was built from scratch, with 25 validators ready to create blocks. The Andromeda chain is already up to 100 healthy validators ready to support and build the ecosystem.

Creating Andromeda’s own Layer 1 chain gives Andromeda Protocol a level of sovereignty it would not have otherwise. Andromeda Protocol’s chain is freestanding, which allows the technology to function without being reliant on any other blockchain.

But why did Andromeda Protocol need its own blockchain and what makes the Andromeda Protocol chain unique? The decision to build its own chain was based on several factors:

  1. First, it is important in organizing and protecting the tech stack. This allows Andromeda Protocol to have complete control when building the technology and the ability to make decisions without being impacted by external factors. This allows Andromeda Protocol to be neutral, free from affiliations or biases.
  2. Having its own chain gives Andromeda Protocol sovereignty. Andromeda Protocol is not beholden to any chain. It is a part of the Cosmos because of the Cosmos SDK and Comet, but it is not subordinate to it. The Andromeda blockchain is not in competition with any other chains.
  3. It needs the ability to run smart contracts on a chain Andromeda Protocol controls in order for the technology to function properly. While the “hub” on the Cosmos chain cannot run smart contracts, the Andromeda chain can. This allows for the ability to deploy our the Andromeda Operating System, or aOS, on-chain soon after launch.

But, the journey doesn’t stop there. Testing and layering are key to its success after deploying aOS, the next stage is to test the Command Line Interface (CLI). In parallel, the indexer is scanning each block and looking for certain actions. This information will then be put into a mutable database, allowing the CLI to query data on the chain.

After the aOS, CLI, and indexer are deployed on Galileo-3, the web app will begin being rolled out in phases.. The first phase is the ADO builder, which allows Andromeda Protocol to deploy on Terra2. This will be a significant milestone because it will allow Andromeda Protocol to move objects and operations across chains. We will be able to see everything in action, all on testnet.

However, the focus is not on getting people to build on the chain. Instead, it’s about having the ability to run the technology without relying on others being impacted by external factors. We want to ensure that the chain is easier, better, and faster than anything else out there.

Building the Andromeda blockchain has been worth the effort. We believe having sovereignty over the system and decisions makes the technology reliable and dependable. The decision to build its own chain allows Andromeda Protocol to run smart contracts and deploy on multiple chains. While it is not in competition with other chains, it is unique in its ability to maintain its own stack. We are excited to see what the future holds for the chain and how it will continue to evolve. This is just the beginning of how Andromeda Protocol makes Web 3 easier, better, faster.
