The Nakamoto upgrade has begun rolling out, learn more!
Nakamoto: Pre-Launch Testnet Activated
March 11, 2024
Hey Stackers, we’ve reached another milestone on the way to the Nakamoto upgrade! Today, the Pre-Launch Testnet (fka Argon for all you OGs!) was ‘Activated’, making the Nakamoto rules live. This means developers can now interact with all the new code that makes Nakamoto so exciting.
Nakamoto rules are the logic that makes Nakamoto different than the version before it called Stacks 2.4. The key difference is that under Nakamoto, block validation logic requires Signers to sign the blocks to be confirmed as anchor blocks. At Step 1 (Instantiation), this logic, or the ‘Nakamoto Rules’ remains inactive, meaning the network follows the block validation rules of Stacks 2.4. Once the testnet (and later mainnet) reaches Activation, the network switches to running these Nakamoto rules and all the features we’re excited about go live for everybody.
The Pre-Launch Testnet offers accelerated <= 2-day cycles to help developers simulate behaviors and outcomes in their applications much faster. As these developers use the testnet, Core Developers will continue to gather valuable insights for further enhancements. In addition, most of what they create on testnet should be a seamless transition to mainnet!
If you’re not familiar with the Nakamoto rollout process, this post is key to helping you navigate. The short version is each testnet and then mainnet follows the same two-step rollout process: Instantiation, then Activation. Today, the Pre-Launch testnet has reached the Activation step and is therefore ‘launched’. It will be continually upgraded as we go along and developers should expect some bumpy performance and bugs along the way.

Primary Usage: Core Developers, (some) App Developers
About:
Next: The Pre-Launch testnet is set to move to Step 2 (Activation) on March 11th, meaning at that point it will be a complete testnet representation of the network with the Nakamoto rules live (except of course that it moves through blocks much faster).
Get Started: Hop to the Docs
About:
- This testnet will exist until the Nakamoto launch is complete and features an accelerated Stacking cycle length of 2 days so that core devs and builders can simulate a lot of blockchain history (and PoX cycles) in a short time.
- This testnet can run against Bitcoin Regtest or Bitcoin Testnet
- Given ongoing audits and testing, this testnet may have bugs, be reset, or run into occasional performance issues as tweaks are made.

About:
Status: This testnet is expected on March 25th
About:
- This testnet features the standard one-week accelerated Stacking cycles that Stacks developers are familiar with on the current Stacks Testnet
- This testnet will always run against Bitcoin Testnet
- This testnet will be the ‘main’ Stacks Testnet going forward and maintained into perpetuity alongside mainnet as a service for any developer or partner starting to work with Stacks.
Status: This testnet is expected on March 25th
Get Started
For developers who are looking to try Nakamoto, you have two paths:
Expect some bumps and bugs, but try Nakamoto today!
You can jump into the docs and code today and understand that while the testnet won’t be perfect, but you’ll have an accelerated Nakamoto environment and can begin building out your applications and smart contracts. This will be especially helpful for any developers interacting with the new pox-4 contract. To get started on this path, here are the links and resources you may need:
Check out the docs for a walkthrough of how to start experimenting with the testnet

Pre-Launch Testnet Links:
- API status endpoint: https://api.nakamoto-1.hiro.so/extended/v1/status
- Burn Block endpoint: This will allow you to get the hashes of fast Stacks blocks as they are added to the chain and see their associated burn blocks. https://api.nakamoto-1.hiro.so/extended/v2/burn-blocks
- New stacking contract: pox-4.clar is the new stacking contract for Nakamoto. If you are interested in experimenting with proof of transfer use cases including state changes, solo stacking, and pool stacking, all the functions you’ll need can be found at the deployed contract.
- Stacks Explorer: The explorer will allow you to view fast blocks as they come in. Be sure to turn on “Live updates” to see them coming in in real time (see image above).

Try the Nakamoto Testnet on March 25th
You can wait until roughly March 25th for the Nakamoto Testnet which will offer more complete documentation and an overall smoother experience. You can read more about this and the associated testnet program below.
Waiting for the Nakamoto Testnet is the path we recommend for most as well as for prospective Signers. If you’re interested in following this path, please enter your email here to receive a notice when it is available. Signers, please feel free to enter your email or get in touch here.

Nakamoto Testnet Program
Next up will be the more formal Nakamoto Testnet expected around March 25th. This will be brought online as a more managed service for builders and partners and is the testnet that will be maintained alongside the live network. You can think of the Nakamoto Testnet as a refinement of the Pre-Launch Testnet that builders can depend on going forward, whereas the Pre-Launch Testnet’s main purpose to date has been serving the Core Developers as they did the heavy lifting on the protocol.
Along with it, the Nakamoto Testnet Program will kick off. Much like the program help for the sBTC Developer Release, this is a program designed to help app developers, Signers, and others test their builds and get ahead of their mainnet launch. This will offer invaluable feedback to developers about their apps and to the Core Devs as they fine-tune the release.
As part of this testnet program, we have lined up 50 testers for each app in the program. These testers will use the app and provide valuable feedback via survey and direct commentary on functionality and usability. This feedback loop is crucial for refining the signing process, enhancing user experience, and improving documentation. We’re grateful to apps like Hermetica, Velar, Uasu, and others who are already working with us on this!
To be considered for the program, developers can join any of the next two open Office Hours sessions with Kenny Rogers, Developer Advocate here at the Stacks Foundation.
In addition to onboarding more developers, the BD Working Group and some Core Developers will spearhead efforts to onboard Signers to the Nakamoto Testnet. This effort will include one-on-one calls to gather feedback from Signers, ensuring they understand the nuances of the signing process and are equipped for a seamless transition to mainnet upon release. If you’re a Signer interested in support, please visit the sBTC Signer page, click Get Started, and enter your information.
