What is the Nakamoto Release?

Summary: The Nakamoto Release updates the Stacks blockchain, focusing on better useability. It speeds up transactions and boosts security to match Bitcoin's level. The release brings in sBTC, enabling Bitcoin's features in a more flexible, programmable way on Stacks. It also changes how blocks are made, now involving Stackers (STX stakers) more in the process.

Timed with the Bitcoin halving to broaden its reach and effect, this update aims to enhance blockchain tech by merging Stacks' new features with Bitcoin's established security, marking a notable advancement in the field.

What is the Nakamoto Release?

The Nakamoto Release is set to transform the Stacks blockchain by enhancing its connection with Bitcoin significantly. This upgrade leads to faster transactions and ensures transactions are as permanent as those on Bitcoin. It introduces sBTC, a programmable version of Bitcoin, strengthening the link to Bitcoin and paying homage to Satoshi Nakamoto, its creator.

In this update, the method for creating Stacks blocks changes from being dependent on miner elections to a system where miners produce blocks consistently, using a fixed schedule. For a fork to happen, it would require the approval of 70% of PoX Stackers, making any reorganization as challenging as it would be on Bitcoin. 

In sum, the update aims to speed up transactions, solidify transaction finality, reduce miner extractable value (MEV) risks, and improve reorganisation resistance.

How Does the Nakamoto Release Work?

The Nakamoto Release introduces significant enhancements to the Stacks blockchain, aimed at improving its efficiency and integration with Bitcoin. Key to this update is the role of Stackers, who are participants that lock up their STX tokens to support network consensus and security. Here’s how the update works:

• Faster Block Production: By separating Stacks block production from Bitcoin block times, miners can now generate multiple Stacks blocks within the span of one Bitcoin block, significantly speeding up transaction processing.
• Stacker Collaboration: For a block to be added to the blockchain, Stackers must collectively approve it. This process is crucial for maintaining consensus and for Stackers to earn their PoX rewards.
• Governance by Stackers: Stackers ensure the blockchain remains consistent and fork-free by endorsing the last confirmed block and only accepting new blocks that build on this agreed-upon foundation.
• Enhanced Blockchain Integrity: Miners are required to link their block commitments to the history of both the Stacks and Bitcoin blockchains, ensuring a secure and continuous ledger.
• Fair Mining Practices: Adjustments to the mining process aim to prevent the exclusion of honest transactions for personal gain, ensuring a more equitable network.

This overhaul not only boosts transaction speed but also fortifies the Stacks network’s security, with Stackers playing a central role in its governance and integrity.

What is sBTC?

sBTC is a new asset introduced with the Nakamoto Release on the Stacks blockchain. It's essentially Bitcoin but made programmable for developers and users. sBTC maintains a 1:1 value with Bitcoin, allowing the secure, reliable aspects of Bitcoin to be used in smart contracts and decentralized applications on Stacks. This creates opportunities for Bitcoin to be more than just a currency or store of value, it can now be used in various blockchain applications without losing its core characteristics.

Downsides of the Nakamoto Release

The changes brought by the Nakamoto Release lead to discussions on its impact on the Stacks blockchain's security reliance on Bitcoin. Previously, Stacks closely tied its security and operations to Bitcoin, a method proven to be robust and secure. With the new release, Stacks moves towards a model where it handles transactions more autonomously, raising concerns about whether this could lead to a reduction in the security benefits derived from Bitcoin.

While the intent is to improve the system's efficiency without sacrificing security, there's a nuanced change in how Stacks ensures its network's safety. This adjustment in the security model aims to maintain strengths while enhancing the platform's scalability and transaction speed.

Nakamoto Release Date

The rollout of the Nakamoto Release is planned to coincide with the next Bitcoin halving, a move aimed at harnessing this critical time for maximum impact and broader adoption. This timing is symbolic, marking a fresh chapter in Bitcoin’s story, but it’s also practical, positioning the Stacks network to make the most of the increased attention Bitcoin receives during this time. 

After the Nakamoto Release, the focus will shift towards further improvements, including refining the sBTC mechanism to better integrate and function within the Stacks and Bitcoin ecosystems.

‍

Bottom Line

The Nakamoto Release is a significant update for the Stacks blockchain, focusing on enhancing transaction speeds and deeper Bitcoin integration. It introduces sBTC, making Bitcoin programmable for a wider range of applications. Adjustments in block production and the strengthened role of Stackers aim to make transactions quicker and the network more secure, without sacrificing Bitcoin's proven security framework.
