You know an ecosystem is truly blossoming when it’s actually hard to compile quarterly updates and make them fit in a single email. It’s always amazing to see just how much gets done toward our mission of building a user-owned internet on Bitcoin every 3 months.
I’m thankful for the many long days and late nights I see from the PBC team and from community members throughout the world as we collectively push toward the launch of Stacks 2.0. It will be an incredible moment for the Stacks ecosystem as well the crypto industry, as we bring a world of new possibilities to Bitcoin via apps and smart contracts.
While I know we’re all looking ahead at Stacks 2.0, it’s important to take a moment to celebrate what’s been done recently. Here are some of my favorite recent highlights (please don’t miss many more below):
If you take one thing away from this message, it’s buckle up! The time between now and mainnet should be filled with plenty of opportunities to get involved with events, ecosystem entities, and the Stacks community. The Blockstack PBC (soon Hiro Systems PBC) team has moved out of Slack and onto Discord full time to be closer to the community on a daily basis, so please connect with us there if you haven’t already.
Last, but not least, look out for information on the Stacks 2.0 launch event soon.

Over the past few months, we worked with the community to establish branding that visually captures the spirit of the ecosystem and we were thrilled to unveil the brand system for Stacks. The Stacks blockchain and Stacks (STX) cryptocurrency are the fundamental building blocks upon which a vibrant ecosystem is growing and now we have a brand that unites us.
Blockstack PBC Is Becoming Hiro, Celebrating its Cypherpunk Roots and Developer Community
Blockstack PBC will soon become Hiro Systems PBC, or 'Hiro' (pronounced he·ro), and our primary focus will narrow to providing developers the tools they need to build a new internet on Bitcoin. This change will come as our work on the Stacks 2.0 public infrastructure winds down after launch and the Stacks ecosystem continues to decentralize and grow. The change to Hiro is both a signal of our commitment to developers, as well as a practical change designed to shift focus (previously often put on Blockstack PBC) to the Stacks ecosystem. → Learn More
In early October, Blockstack Co-Founder, Muneeb Ali published a comprehensive model that allowed users to estimate potential earnings based on various assumptions and variables, such as participation rate, the number of miners, transaction fees, as well as others. Coupled with the implementation of Stacking on the testnet, we’re seeing a lot of excitement about this type of novel value-creation mechanism. → Stacking Calculator

Decentralization and Partnerships
Daemon Technologies Launch
Last quarter, we welcomed a new Asia-based entity, Daemon Technologies, to the Stacks ecosystem. Headquartered in Hong Kong, it will serve as an important entry point and hub for the Stacks Ecosystem in Asia, while further decentralizing the ecosystem. Daemon’s Founder and CEO, Xan Ditkoff, has been on the ground in Hong Kong, researching, preparing, and launching Daemon Technologies. Daemon plans to experiment with software that leverages the Proof-of-Transfer infrastructure of the upcoming Stacks 2.0 chain, including an open-source mining bot. → Learn More
Freehold: Empowering The Stacks Community
In September, yet another entity joined the Stacks Ecosystem. Freehold, founded by former Blockstack PBC Head of Growth, Patrick Stanley, will be taking on the role of empowering tightly knit communities to collaborate on open protocols, starting with Stacks. Freehold is the ‘Contribution Entity’ as outlined in the Stacks ecosystem’s path to decentralization. Freehold’s initial goal is to advance ideas and projects in the space by first encouraging active contributions to the ecosystem. Members will later be able to earn rewards by completing various challenges related to community building. To learn more or get involved with Freehold, go to joinfreehold.com.
Chainlink: Stacks 2.0 + Chainlink Oracle Technology
Blockstack PBC and Chainlink announced that they are joining forces to integrate Chainlink as the preferred oracle solution for the Clarity smart contract language. The initial integration will revolve around integrating Chainlink’s widely used Price Feeds, but will likely evolve into a generalized oracle solution for Stacks 2.0. → Learn More
Blockdaemon to Provide Robust Node Tools for Stacks 2.0
In August, we announced a partnership with Blockdaemon to provide a seamless path to running a Stacks 2.0 node. Blockdaemon makes it possible for users to directly launch Stacks 2.0 nodes with just a few clicks via their marketplace → Learn More
Clarity Arweave Bounty & Integration
Last month, Blockstack and Arweave teamed up to host a bounty for a compiler that would allow Clarity smart contracts to run on the Smartweave platform. The bounty was a success! Arto Bendiken built Sworn, a compiler that parses .clar files and translates them into an equivalent SmartWeave program in the form of JavaScript code.
The core theme of engineering related work in Q3 continued to be Stacks 2.0.
PoX Mining & Stacking (Krypton Phase of Testnet)
September 24th marked one of the most significant milestones yet on the path towards the launch of Stacks 2.0: Phase 3 of the Testnet (Krypton), including a full implementation of Proof-of-Transfer (PoX), was made live on the testnet. This means that developers and miners are able to interact with the full PoX mechanism, and users can experiment with Stacking rewards. It also means that over 90% of the design for Stacks 2.0 from our whitepapers have now been implemented! → Learn More
Transaction Signing with Blockstack Connect
At the end of July, a brand new version of Blockstack Connect went live for developers who want to build apps that sign transactions with Clarity smart contracts on the Stacks 2.0 Testnet. This is mission critical infrastructure for nurturing a vibrant and versatile dApp ecosystem. We’re looking for feedback from developers on specifically how this release satisfies their immediate development and testing needs. → Learn More and Try It Out
This September, we unveiled a significant docs refresh both inside and out. The docs were updated to use new tooling (Next.js + MDX) and an improved design that meshes with other properties. Page speed scores went from 60s to upper 90s, and styling was standardized via @blockstack/ui. They even added a beautiful new dark mode. → Go to the docs
Recently, we announced the Stacks.js public beta! Stacks.js is a reorganization of libraries in the Stacks ecosystem, composed of nine modular libraries all residing within a single Github repository. With Stacks.js, you get everything you need to build apps on Stacks 2.0. If you have an existing app, read the migration guide. → Learn More
To accompany all the experimentation happening on the Stacks 2.0 testnet, we released a specialized blockchain explorer to make developers’ lives easier! This tool is your one-stop-shop for looking up transactions, requesting funds from the faucet, deploying contracts, or playing in the Sandbox. → Try it
Stacks Hackathon Series & Clarity Hack Winners
This summer we announced the Stacks Hackathon Series to incentivize robust experimentation and development on the Stacks 2.0 testnet. The first event in the series was Clarity Hack, a month-long sprint to produce powerful smart contracts written in the new Clarity programming language. The results exceeded all expectations, and there were a multitude of fully-fledged, useful, open-source smart contracts including an adaptive currency, a library for uint-256 numeric values, and even a crowdfunding mechanism! → Winners
→ The Stacks 2.0 Hackathon is still ongoing with HacksStacks and HackDefi!
