Blockstack April 2019 Overview blockstack.org

This communication may be deemed “testing the waters” material under Regulation A under the Securities Act of 1933. This process allows companies to determine whether there may be interest in an eventual offering of its securities. We are not under any obligation to make an offering under Regulation A. We may choose to make an offering to some, but not all, of the people who indicate an interest in investing, and that offering might not be made under Regulation A. If we go ahead with an offering, we will only be able to make sales after we have filed an offering statement with the Securities and Exchange Commission (SEC) and the SEC has “qualified” the offering statement. The information in that offering statement will be more complete than the information we are providing now, and could differ in important ways. You must read the documents filed with the SEC before investing.

No money or other consideration is being solicited, and if sent in response, will not be accepted. No offer to buy the securities can be accepted and no part of the purchase price can be received until the offering statement filed by the company with the SEC has been qualified by the SEC. Any such offer may be withdrawn or revoked, without obligation or commitment of any kind, at any time before notice of acceptance given after the date of qualification.

An indication of interest involves no obligation or commitment of any kind.

Any person interested in investing in any offering of Stacks Tokens should review our disclosures and the publicly filed offering statement relating to that offering, a copy of which is available on this website.

You may obtain a copy of the preliminary offering circular that is part of that offering statement at stackstoken.com.

What is Blockstack? A complete decentralized computing platform and app ecosystem Blockstack is a full-stack decentralized computing platform that enables a new generation of applications where developers and users can interact fairly and securely. Blockstack builds protocols and developer tools designed to enable a fair and open Internet that returns digital rights to developers and consumers. Led by some of the world's foremost experts on distributed systems, Blockstack allows users to own their data that they can take with them from app to app in the ecosystem, along with their ID that eliminates the need for password-based logins. The end result is privacy, security, and freedom.

The Next Wave of Computing Computing systems have followed a swing of a pendulum, with centralized computing on one end and decentralized computing on the other. The mainframes of the 60s and 70s had a “centralized” computing model where a single mainframe would serve an entire office building. The desktop revolution of the 1980s and 1990s was a massive shift away from mainframes and people had computers in their homes. In the 2000s and 2010’s we saw a shift towards cloud computing. Our laptops are just screens and all of our compute-jobs go to the cloud. The next wave of computing is going to be a shift away from cloud computing towards decentralized computing. Blockstack aims to accelerate and facilitate this new age of decentralized computing.

The History of Blockstack Blockstack was started by Muneeb Ali & Ryan Shea in 2013 out of the CS department at Princeton University. The project was largely in R&D stage between 2013 to 2016 and a first component of Blockstack, a decentralized identity system, launched in March 2014. Blockstack graduated from Y Combinator in the Summer of 2014. Union Square Ventures (USV) led the Seed round. In 2016, three peer-reviewed research publications come out of the work. In 2016, development began on the core platform and the team raised $4M in a Series A funding round led by Union Square Ventures. In 2017, the Blockstack developer platform was launched with a developer-release of Blockstack Browser and Gaia, a decentralized storage system.

Conducted a token offering in Q4 2017 which resulted in ~$50 million total raised, and over 800 accredited investors, qualified purchasers, and institutions participating. In 2018, the Stacks blockchain testnet launched. Other launches included iOS and Android SDKs, multiplayer storage, and the Stacks wallet. Hosted Blockstack Berlin, keynoted by Edward Snowden. In 2019, ramped App Mining pilot to include 65 independent startups, launched iOS and Android authentication, and released prototype of virtual machine (VM) for Stacks smart contracting language. In 18Q4, the Stacks Blockchain launched, tokens were distributed and the first Stacks transaction was sent. Achieved Milestone 1, unlocking $25M in capital. Launched App Mining Pilot. Held the Decentralizing the World Tour with 31 global meet ups.

How Blockstack Works Users download Blockstack and it installs everything they need to gain access to the new internet for decentralized apps. Users create an account and a keychain is created on user devices. This keychain lets them sign and encrypt their files locally before it is synced and backed up to the cloud, enabling true data ownership. Users create and verify the first identity they truly own, a Blockstack ID. This means strong protection against account hijacking and impersonation. Users can rest easy knowing they’re talking to the right people and signing in to the right apps.

Application Growth 65 Startups have launched production apps on our infrastructure in the past 5 months. App Mining, an app growth engine, is accelerating developer adoption. App Growth We worked with Princeton and NYU game-theorists to build funding mechanism to incentivize app developers and catalyze an app -quality flywheel. Only $100K flowing through pilot (10x increase soon).

Developer Growth 2,375 Developers attended our recent Decentralizing the World tour which included 47+ meet ups internationally and 3 larger events in Hong Kong, London, and New York City. Community Member Growth The Blockstack community is filled with enthusiastic members across the forums, the mailing list, the Slack group, the subreddit, and the meet up groups. Developer evangelists congregate in their own Slack channel an d coordinate about events and best practices on weekly conference calls.
