Launch the Testnet

Why does Aleph Zero
need a testnet?

Testnet is a part of our development process. Initially, new features are deployed to Aleph Zero internal devnet. Later on, they're moved to testnet, where we can battle-test different solutions together with our community.

This is just the beginning! We will be communicating exciting news as soon as we know about it. 

A powerful, scalableand open sourceinfrastructure layer

Aleph Zero is a public blockchain that has been designed to offer superior speed, security, and scalability. It boasts a DAG-based consensus protocol and an integration with customized Substrate modules. The protocol is also distinguished for being peer-reviewed and garnering academic support. 

More Features


Level 1

Only ten nodes will operate at this stage. The first feature revealed is native token transfer. Our first step towards operability! 

Level 2

25 nodes will function. The network will be hosted by AZF, CC, and validators chosen from an authority list. We will update the authority list every couple of days. At this stage, smart contracts will be implemented. 

Level 3

100 validator nodes with random selection. Validators are required to stake coins (provided by AZF to everyone on the authority list). Features? Wrapped coins, bridges, DEX, and more.

Level 4

At this stage, the validator list will include 200 entities, including select members of the public. DAO treasury voting will be introduced, and smart-contract-based bridges to popular network will be created.

Frequently asked questions

With the launch of Aleph Zero’s testnet last month, we’ve seen extensive interest and $TZERO transactions being executed every 10 seconds on average. As we move forward with building and launching the next levels of the testnet, we’d like to share our Frequently Asked Questions (FAQ).

How long will each level last? 

Setting up a testnet is a difficult process that isn't just about delivering a product, it's also a great educational tool for our development team to troubleshoot every single aspect of the protocol before launching the mainnet. Before moving on to the next level we want to bulletproof every network feature. We will be announcing the launch of a new level 7-14 days in advance, but only once we are 100% sure that the current level is running without a catch. 

Do you plan to launch an incentivized testnet? 

An incentive program will be launched to battle-test new features. To be up to date with the details on how to take part in this process remember to follow us on our communication channels for sign-up announcements.

How do I get on the validator authority list? 

The validator authority list will be centrally managed by our project team and it is going to be run on an invite-only basis. To ensure smooth collaboration and to maximize network uptime we have decided to cooperate with professional validators only. To become a part of the list we are going to favor diversity and professionalism. A sign-up form will soon be readily available for you to put forth your candidacy. 

When will the testnet open to the public? 

The testnet will become open to the public as we move from Level 2 to Level 3. Sign-ups will be open beforehand. This will be communicated through our communication channels. 

Will I be able to run nodes on Amazon Web Services? 

It will be possible to run a node through AWS, but only a limited number of validators will be permitted to do so. You can check out the hardware recommendations and requirements here

How many validators will be onboarded to the testnet? 

As we progress through our four testnet levels more participants will be invited to take part in this exciting process. The exact number of participants cannot be stated at this stage as it will depend on our operational support capabilities We can use all the help we can get so if you'd be interested in assisting our DevOps team, please contact us via A more detailed roadmap regarding the number of participants that will take place can be found here.
