Frequently Asked Questions

What is Blockstack?

Blockstack is a full-stack decentralized computing network that enables a new generation of applications where developers and users can interact fairly and securely. Blockstack uses blockchain technology to build 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 own data that they can take with them from app to app in the ecosystem, along with their Blockstack ID that eliminates the need for password-based logins. The end result is privacy, security, and freedom.

What is decentralized computing?

Decentralized computing has these attributes:

  • Personal keys for a digital life. Users will have keys that unlock all their software interactions, email, subscriptions, and social. These keys are in users’ hands and under their control similar to physical keys (in some cases they are physical). Corporations no longer create or manage these keys.
  • Security is a first-class concern. Users want systems that protect both their identity and the data associated with that identity — health, application, and relationships.
  • Convenient and auditable. Applications will be readily available as cloud applications are today but will be written with open protocols and code that allow them to be audited.
  • Innovation focused. The code and data in a decentralized computing lacks corporate and other boundaries, as a result, a global workforce can easily contribute and benefit from them.

Blockstack technology is a shift in how people use software, create it, and benefit from the internet. It puts people back in control of the computing systems that manage today’s world.

What is the Blockstack Ecosystem?

The Blockstack Ecosystem is the legal entities and community structures that support the Blockstack technology, the apps that rely on it, and the people that work with it. The ecosystem’s mission is to foster an open and decentralized Internet that establishes and protects privacy, security, and freedom for all users.

There are multiple business entities that have been created to focus on advancing the ecosystem, with plans for further decentralization:

  • Blockstack PBC is a Public Benefit Corp that drives the development of the core Blockstack protocol and developer tools. Blockstack PBC was founded in 2013 by Princeton computer scientists and after 4+ years of R&D, launched the Blockstack Platform alpha in early 2017. The Blockstack Platform is the easiest way to start building decentralized, blockchain-based applications. It provides a complete decentralized application stack, powered by the Stacks blockchain, and maintained by a open-source community.
  • Blockstack Token LLC is the entity responsible for developing and commercializing the Stacks tokens in a manner that is approved by the SEC. Blockstack Token LLC works on regulatory filings and compliance for the Stacks token. The LLC conducted the 2017 token offering to accredited investors. Stacks tokens created by Blockstack Token LLC were distributed in the genesis block of the Stacks blockchain in Fall 2018.
  • Blockstack Signature Fund I is a fund comprised of multiple VCs representing $25 million in funding that makes opportunistic investments in the ecosystem &emdash; whether it be Blockstack applications or into tools and platforms that accelerate the growth of the ecosystem. Learn more about the Signature Fund.
  • Non-profit Foundation Blockstack PBC intends to assist in the formation of a non-profit foundation dedicated to supporting fundamental digital rights and ensuring that core internet infrastructure remains decentralized. In the future, it may support people and projects with funding, research grants, or other.
  • New Internet Labs is an independent company headquartered in Hong Kong and founded by Larry Salibra, an early employee of Blockstack PBC and long-time Blockstack contributor. New Internet Labs serves as an App Reviewer as part of the App Mining program and working to develop a browser for the decentralized internet. Learn more about their efforts here.

Any person or organization working with the Blockstack technology in the open-source ecosystem is considered a part of it. Other than the above entities there are 80+ independent organization and apps built by teams of developers that are part of the Blockstack Ecosystem.

What is a decentralized internet?

We envision an internet where users control their data, and power flows back to the users. A decentralized internet was how the internet was intended to be, a place where application creators cannot sell data without a user’s authorization. Users choose which data to share and who to share it with. In a decentralized internet, no single company or organization tracks users’ activities without permission, and that permission is the users to give or to take away.

What can developers achieve with the Blockstack Ecosystem?

The Blockstack Ecosystem is working to enable developers to build software that protects users’ digital rights. This new kind of software is known as decentralized applications or DApps.

DApps use blockchain technology. Where Bitcoin is a decentralized value exchange on a blockchain, DApps use blockchain technology for more than value exchange; they use a blockchain to exchange data and support application interactions.

Decentralized applications potentially represent the next generation of computing. In an entirely decentralized world, all things occur using peer-to-peer networks, and the idea of centralized entities are non-existent. This distributed future is still being designed and built, but the early stages of development are looking promising.

What problems do Blockstack DApps solve for me as a user?

Applications developed with Blockstack’s technology run like the traditional, web applications you know. Unlike traditional, web applications, DApps avoid abusing users by adhering to the following principles:

  • Users control their data, not the application developer. If you stop using an application, the application cannot access your data. When you leave the application, you take your data with you.
  • Users determine where to store their data. You can store your data on your computer. Alternatively, you can choose highly-available commercial storage providers you trust. The providers can only host your data; it is encrypted so they cannot “unlock” it to view.
  • Users control which applications and which third parties can access their data. Applications ask your permission to read your data, and you can withdraw those same permissions at any time. Applications cannot sell or mine your data on behalf of a third party you are unaware of.

What problems does Blockstack solve for application developers?

  • Blockstack wraps blockchain operations in traditional REST calls. Developers can start programming using the same Javascript functionality they are currently familiar with.
  • Application data is stored off the blockchain for performance and scalability.
  • Blockstack ensures that all user data is signed and verified and (optionally) encrypted end-to-end, so users and developers can treat storage providers like dumb hard drives.
  • Developers do not host user data. Since users supply their storage and use public-key cryptography for authentication, applications don’t have to store anything–there’s nothing to steal when applications are hacked.
  • Moreover, many Web applications today can be refactored so that everything happens client-side, obviating the need for running dedicated application servers.

Who started Blockstack?

Blockstack was founded by two engineers from Princeton University, Muneeb Ali and Ryan Shea. They met at the Computer Science department at Princeton, where Muneeb was finishing his Ph.D. and Ryan was running the entrepreneurship club. In 2013, frustrated by the walled-gardens and security problems of the current internet they started working on a decentralized internet secured by blockchains. Blockstack is an open source project, and you can find the code on GitHub.

What is a decentralized application or DApp?

Decentralized applications or DApps are a new type of software application built with blockchain technology. Where Bitcoin is a decentralized value exchange on a blockchain, DApps use blockchain technology for more than value exchange; they use a blockchain to exchange data and support application interactions.

How do DApps differ from applications I typically use?

DApps (decentralized applications) differ from Web applications in these key ways:

  • Users have identities, not accounts. The user brings their identity to the applications; applications do not require the user to create accounts and passwords. A user can use a single identity on all applications.
  • Users determine where to store their application data. They can store their data on their computer or with a commercial cloud storage provider.
  • Users control data access. Users control access to their data. Software creators and their decentralized applications don’t keep or save your data. When a user logs into a DApp with an identity, the user gives the DApp authority to read existing data or write new data. When a user disconnects from a DApp, it no longer has access to the user data.

Do DApps work with a regular browser?

Yes! DApps run in the web browsers (Chrome, Safari, Internet Explorer, and so forth) you know today.

What is an identity or ID or Blockstack identity?

A name or identity, ID for short, is your “home” on the decentralized internet. Your identity is unique, like a passport number, only you have it. To use an application, you sign into the application with your identity and a secret key only you know.

Your data and where it is stored is connected with your identity. When you sign into a DApp, you give the DApp permission to read your data and write to your data store on your behalf. When you log out of an application, it no longer has access to your data or data store — until the next time you log in with your identity.

Do I need to keep my identity secret?

No. You can tell people your identity just as you tell them your name. What you need to secure and protect is your secret key.

How do I get an identity? Is it free?

Normally, registering an identity as a digital asset on the Stacks blockchain requires burning of Stacks tokens as fuel. However, Blockstack PBC is currently running a free service to pay for identities on behalf of the users. Through this service, you can get a free identity from Blockstack in the id.blockstack namespace. A namespace is similar to a domain (checklist.com, for example) on the old internet. So, a free identity has blockstack suffix in its name; for example, moxiegirl.id.blockstack is a free Blockstack identity.

If I forget my identity or my lose my secret key, can Blockstack help me?

If you forget your identity or lose your secret key, no one else, no person, no software, can help you get your identity back. This restriction protects your identity and your secret key which together control access to data about you. In the new, decentralized internet, no one can keep and store your data but you, not even Blockstack.

You need to keep your identity and secret key in a safe, secure place you won’t forget.

Where is my identity kept?

When you create an identity, your id and your private key are hashed (encrypted) and registered on Blockstack’s blockchain. The data you create through your identity is encrypted and kept off the blockchain in your data storage.

Can Blockstack delete my Blockstack ID or deny me use of it?

No. When you’re using a Blockstack client, you control your data and ID with a private key. As long as no one gets access to your private key, no one can control your data or ID. When you use Blockstack, by design, your private keys are never sent to any remote servers.

Can I get an identity without the Blockstack in the name, like steve.id?

Yes, you can get an identity in the .id space without Blockstack in the name. For example, you can create steve.id. You can even create a different space like username.frank without the id designation. These identities (.id) are not free; they cost a small amount of Bitcoin. A space (.frank) takes some technical knowledge to create and cost more.

Can I have more than one identity?

Yes, you can create as many identities as you want.

Do identities last forever or do they expire?

Identities with the like moxiegirl.id.blockstack or subdomain.name.namespace format do not expire. Names that have a single dot like name.namespace expire according to the rules set by the namespace creators. For example, name.id in the id namespace expires every two years and must be renewed. If a name.id expires, someone else can claim it.

Why do DApps ask me for an email in addition to an identity?

Your email is not kept by DApps or by Blockstack. It is stored in your browser client’s local web storage. (See the question about data storage for more information about web storage.) When you are logged into a DApp, it can use your email to send you any information you need to operate the DApp. When you log out, your email is no longer available to the DApp.

Where can I find Blockstack DApps that I can use?

You can see a list on the App.co site. Alternatively, you can go directly to your Blockstack Browser home page.

What is the Blockstack Browser?

The Blockstack Browser is a DApp used to create and manage Blockstack identities. To a user, it looks just like another tab in a standard browser. From the Blockstack Browser tab, you can find DApps to try, update settings related to your identity and storage – and much more.

Developers use the Blockstack Browser to handle login requests from DApps. From a Blockstack DApp, a user chooses the Log In with Blockstack button. Clicking this button sends users to a Blockstack Browser dialog. This dialog asks users to allow the DApp to access their data.

Do Blockstack DApps work with my web browser?

Yes! DApps using Blockstack run in the web browsers you know and love (Chrome, Safari, Firefox, and Edge). Blockstack DApps are web applications; they happen to use the blockchain. DApps are just as fast as traditional web applications, often more so. If you use our Web-hosted Blockstack Browser, you can get started using DApps right away.

Is there a downloadable version of the Blockstack Browser?

Yes. You can download a desktop version of the Blockstack Browser here.

What is Gaia?

The Gaia Storage System is a feature of the Blockstack Platform. Developers or organizations can use the Gaia Storage System to create a data storage provider. Users choose a data storage provider when they create an identity.

Where is the data about me kept or what is a data store?

Data about you appears in two locations, browser web storage and a data store. Web storage lives in your browser client, Chrome, Safari, and so forth. Data in web storage is sparse, it never leaves your device (computer or phone), and it is temporary. You can clear or remove your web storage just as you can your browser’s cache. Web storage data includes your email and your encrypted identity. Web storage never leaves your browser and never crosses a network to an external server.

Your Blockstack identity and any connected application data are kept in your data store. Unlike web storage, a data store has to live on a server accessible via the internet. That server is running the Gaia Storage System. The Gaia Storage System keeps the data encrypted. When you use an application, you give it permission to read and write from your data store. The application needs your permission to decrypt the data.

What kind of data does a Blockstack DApp keep about me?

Blockstack does not keep any data about you. When you login into an application, you are asked to provide an email. That email is in your browser’s web storage; it doesn’t leave your device (computer or phone). When you reset the Blockstack Browser or clear your browser’s web storage, the local storage and your email are removed.

What is a data storage provider?

A data storage provider is a person or a company that runs a Blockstack Gaia Storage System. You could, for example, run a Gaia Storage System on your own. Blockstack assumes that most users will use a commercial storage provider rather than a personal one.

Commercial storage providers typically use cloud computing services such as Digital Ocean, Amazon, or S3. These have the advantage of larger drives, regular backups, and more secure storage. Individual users can use these too, or they can use a local drive.

A Gaia Storage System has a location (URL) on the internet. The URL for a user’s storage provider is stored in their zone file. You can get a zone file with blockstack-cli lookup in the CLI. See the CLI documentation for more information about available commands.

Can I move my data from one storage provider to another?

Currently, moving your data from one storage provider to another is not supported via the UI. You can do this move with assistance from Blockstack.

Who should build with the Blockstack Platform?

Everyone! However, more seriously, if you are building an application in JavaScript that requires sign-in and storage, you should look at using Blockstack.

I’m a web developer. Can I build on the Blockstack Platform?

Yes! Blockstack is geared primarily towards web developers. All of your existing knowledge is immediately applicable to Blockstack. Anything you can do in a web browser, you can do in a Blockstack app.

I’m a non-web developer. Can I build on Blockstack Platform?

Yes! Blockstack implements a RESTful API which lets you interact with Blockstack from any language and any runtime. In fact, the reference client (blockstack.js) is mainly a wrapper around these RESTful API calls, so you won’t be missing much by using a language other than Javascript.

How do I get started using Blockstack to build decentralized applications?

The Zero-to-Dapp Tutorial is the best place to learn to build with Blockstack. The tutorial takes you through key aspects of building with Blockstack and takes less than 60 minutes. If you want something short and sweet, we have a Hello World that takes about 10 minutes. In the end, you’ll have a working demo and even get a free limited edition t-shirt!

What’s the difference between a web app and a Blockstack app?

Blockstack apps are built like single-page web apps — they are, in fact, a type of web application.

Blockstack apps are a subset of web applications that use Blockstack’s technology to preserve the user’s control over their identities and data. As such, they tend to be simple in design and operation, since in many cases they don’t have to host anything besides the application’s assets.

Do I need to learn any new languages or frameworks?

No. Blockstack applications are built using existing web frameworks and programming. The only new thing you need to learn is either blockstack.js or the Blockstack RESTful API.

What is the general architecture of the Blockstack Platform?

Applications built with Blockstack are serverless and decentralized. Developers don’t have to worry about running servers, maintaining databases, or building out user management systems.

Developers build an application in Javascript using the blockstack.js library. This library handles everything from identity and authentication to data storage. Applications can request permissions from users for read and write access to user resources. Data is stored off the blockchain in a storage provider running Blockstack’s Gaia Storage system. Gaia is simple and reliable and uses existing cloud infrastructure.

Under the hood, Blockstack provides a decentralized domain name system, the Blockstack Naming System (BNS). BNS is a decentralized public key distribution system and registry for apps and user identities.

What is a “serverless” app?

The application should not run application-specific functionality on a server. All of its functionality should run on end-points. Serverless can also mean applications where the application developer still writes some amount of server-side logic, but unlike traditional architectures, this logic is run in stateless compute containers that are event-triggered and ephemeral (may only last for one invocation).

However, applications may use some servers with the caveat that they must not be part of the application’s trusted computing base. The Gaia Storage System is part of most DApps’ computing base, but because user data is signed and verified end-to-end, the storage systems are not trusted to always serve correct data.

How does my web app interact with Blockstack?

The blockstack.js library gives any web application the ability to interact with Blockstack’s authentication and storage services. In addition, we supply a public RESTful API.

What does blockstack.js do?

This is the reference client implementation for Blockstack. You use it in your web app to do the following:

  • Authenticate users
  • Load and store user data
  • Reuse users’ public data in your application

There are also mobile libraries for iOS and Android.

How do I use blockstack.js?

Our documentation has several examples you can use to get started.

How do I register Blockstack IDs?

You should use the Blockstack Browser.

How can I look up names and profiles?

You can use blockstack.js, or you can use the public Blockstack Core endpoint.

What kind of scalability and performance can I expect from applications built with Blockstack?

Blockstack uses the blockchain only for name registration. Data storage is kept off-chain in the Gaia Storage System. This basic application architecture means any application can perform and scale as they do without a blockchain.

Is there a limit to the file sizes I can store in a Gaia Storage System

The file size limit is 25 MB per file.

Can I run a Gaia Storage System commercially?

Yes, you can. Anyone interested in running a Gaia Storage System can run one and make it available to users.

Is the platform private or open sourced?

The project is open-source, and anyone can contribute! The major contributors are mostly employees of Blockstack PBC. You can see the full list of contributors here: https://github.com/blockstack/blockstack-core/graphs/contributors

What programming language can I use to build these apps?

To make apps that run in the web browser using Blockstack, you can use JavaScript and any of the same web frameworks or libraries you use today such as React, AngularJs, Vue.js or jQuery. Blockstack Core is implemented in Python (the next major release will be in Rust), but you can use any language you like for native apps as long as it can consume a JSON REST API.

How is Blockstack different from Ethereum for building decentralized apps?

You can think of Ethereum as a “heavy” blockchain that does everything for you. All the complexity is handled on-chain, computations are run there, and all scalability and security concerns must be handled at the blockchain level. Ethereum amounts to a “mainframe” that runs all the applications in the ecosystem.

Blockstack puts minimal logic into a blockchain and handles scalability outside of the blockchain by re-using existing internet infrastructure. Our architectural design mirrors how computing has developed; moving from mainframes to smaller networked entities.

Can Blockstack applications interact with Bitcoin? Ethereum? Other blockchains?

Yes! Since Blockstack applications are built like web applications, all you need to do is include the relevant Javascript library into your application.

Where can I buy Stacks Tokens?

Blockstack Token LLC has filed an offering statement with the U.S. Securities and Exchange Commission (SEC) to conduct a $50 million token offering using the SEC Regulation A+ framework. Stacks Tokens won’t be sold until the SEC has qualified the offering statement. Please keep an eye out for updates at stackstoken.com, where you may also subscribe for updates by joining our mailing list.

When can I buy Stacks Tokens?

The timing of the sale depends on if and when the SEC qualifies the offering statement. We hope qualification will be in the near future. Please keep an eye out for updates at stackstoken.com, where you may also subscribe for updates by joining our mailing list.

How much do Stacks Tokens cost?

We are offering up to 215 million Stacks Tokens at a discounted purchase price of $0.12 to current holders of certain non-binding vouchers to purchase Stacks Tokens, up to a maximum of $3,000 in Stacks Tokens to each voucher-holder.

We are offering at least 40 million Stacks Tokens at a price of $0.30 per token to “qualified purchasers” generally (as such term is defined under Regulation A of the Securities Act of 1933). We may, in our discretion, increase the size of the general offering (up to a maximum of 62 million tokens).

Please refer to the preliminary offering circular filed with the SEC here for all information related to the proposed Regulation A offering of the Stacks token.

How are Stacks Tokens priced?

The valuation history of Stacks Tokens is disclosed in detail on page 71 of the preliminary offering circular. Please refer to the preliminary offering circular filed with the SEC here for all information related to the proposed Regulation A offering of the Stacks Token.

Why were Stacks Tokens valued/sold at $0.00012 prior to the 2017 accredited sale at $0.12?

Founders and early employees of Blockstack PBC received tokens at $0.00012 per token in October 2017 based on an independent valuation from Foresight Valuation Group, LLC when the Stacks Token was still in its earliest stage of development and before the publication of the token white paper at the end of that month. This grant was subject to a three-year time lock commencing upon the introduction of the genesis block to the Blockstack network in November 2018, and the nominal price reflected the early, high-risk support of founders and early employees.

Holders of Blockstack’s Series A convertible preferred stock—who had invested a total of $5.1 million as of late 2016 and funded Blockstack’s early growth and development before the decision to create a token, or the drafting or publication of any white papers—were also provided an opportunity to purchase tokens at the $0.00012 per token price. This opportunity to participate at a nominal price was given in return for their early support and in proportion to their equity ownership, and it was based on their reasonable expectation as early investors that they would receive tokens if Blockstack ever decided to create a digital token. These tokens are subject to a three-year time lock, commencing upon the introduction of the genesis block to the Blockstack network in November 2018.

Can I buy Stacks Tokens with either cryptocurrency or fiat currency?

As indicated in the preliminary offering circular, if qualified by the SEC, Stacks may be purchased using U.S. dollars, Bitcoin, or Ether. Please refer to the preliminary offering circular filed with the SEC here for all information related to the proposed Regulation A offering of the Stacks token.

I have a voucher. How do I redeem it for Stacks Tokens?

Vouchers cannot be used to purchase Stacks Tokens until the SEC qualifies the offering statement. At that time we will inform the community on next steps and how voucher holders can purchase up to $3,000 worth of Stacks Tokens at a price of $0.12 per token. Please keep an eye out for updates at stackstoken.com, where you may also subscribe for updates by joining our mailing list.

How do I check the validity of my Stacks voucher?

You may email [email protected] with your voucher ID and full name to check the validity of your voucher.

Can I transfer or sell my Stacks voucher?

Stacks vouchers are non-transferrable and may not be bought, sold or gifted. Only the original person or entity that registered for, and whose name is printed on, the voucher may redeem it.

How do I check the status of my previously purchased Stacks Tokens?

You may check the status of previously purchased Stacks Tokens at https://explorer.blockstack.org/. Additional wallet-related information is available here.

If I am not a U.S. person, can I buy Stacks Tokens?

We anticipate that people in certain foreign jurisdictions will be able to participate upon qualification, but we cannot currently share a list of countries, nor can we give you legal advice. Please keep an eye out for updates at stackstoken.com, where you may also subscribe for updates by joining our mailing list.

You should consult a local attorney in your country to determine whether your local country’s laws prohibit the sale of Stacks to you.

If am a New York State resident, can I buy Stacks Tokens?

No. Due to New York state laws, New York residents are excluded from participating in the proposed Regulation A offering.

Is there an exchange where I can buy and sell Stacks Tokens?

Currently, there is no authorized exchange or alternative trading system (ATS) for buying and selling Stacks or Stacks futures, and we cannot comment on when an exchange or ATS might list Stacks at this time. Please keep an eye out for updates at stackstoken.com. If you see Stacks listed on an exchange, please let us know at [email protected], as the listing may be illegal or a scam.

Can I sell or transfer Stacks Tokens directly to someone else?

If you purchased Stacks from our 2017 token sale, it may be possible to sell or transfer Stacks directly to another person in a peer-to-peer transaction. We recommend you consult an attorney before engaging in such a transaction, especially if buying from or selling to a U.S. person or entity, as we cannot give you legal or regulatory advice.

What is the holding or lock-up period for Stacks Tokens?

For Stacks Tokens under the proposed Regulation A offering, please refer to the preliminary offering circular filed with the SEC here for information relating to the lock-up period.

Stacks purchased from the 2017 token sale are subject to two separate holding or lock-up periods that run in tandem: (1) a one-year holding period required by law that prohibits sale or transfer of Stacks within one year of the date of purchase of the SAFT or fund interests that gave you the right to tokens, and (2) a monthly time-lock built into our blockchain that unlocks 1/24th of your Stacks on the date of the Blockchain launch on October 29, 2018, and then an additional 1/24th approximately each month thereafter. Because the 2017 token sale took place over one year ago, the one-year holding period should be over for most investors. You may check the status of your monthly time-lock at https://explorer.blockstack.org/.

I have a tax question about my Stacks Tokens. Whom should I talk to?

If you have a tax question about your Stacks Tokens, we recommend you speak to an accountant or tax lawyer. If you participated in the 2017 token sale through the Blockstack Token Funds, we’ll provide you with the necessary tax reporting forms by the required deadlines, but in general, we cannot give you tax advice.

What is a seed phrase?

When you create a wallet address, you also create a seed phrase. With one significant exception, a seed phrase is similar to a banking pin in that it gives you access to your wallet and your token allocation. Unlike a pin, if you lose your seed phrase, you can never access your wallet or your token allocation ever again.

Warning: Losing a seed phrase is final and destructive. Blockstack does not keep a copy of your seed. Blockstack cannot give you a new seed, get your access to your wallet, or return your tokens if you lose your seed phrase.

Keep your seed phrase secret. Just as with a banking pin, anyone that knows or steals your seed phrase can access your allocation.

You should write your seed phrase down and store the paper you write on in at least two secure locations. A safe or lock box is a good location. You can also store it online in an encrypted password manager such as 1Password. You should never simply store a seed phrase in Apple Cloud or Dropbox.

How do I keep my tokens secure?

The safety of your Stacks Tokens is extremely important to us. To help ensure that you complete the process of receiving your tokens correctly and securely, please read the following guidelines:

  • Website Safety: When inputting data on a website or verifying the presence of data on a website it is essential that you confirm that the URL is correct and that your browser is using HTTPS.

  • Email Safety: Blockstack will never ask for your personal identifying information over e-mail, or call you directly. When we ask verifying questions, we will only do so when you call us to confirm your identity. We will never ask you for money or your Seed Phrase (private key).

If you have large token holdings, make sure you take advantage of custodial services. A wallet does not provide the security of a custodial service.

When will the new Stacks wallet be available?

The Stacks wallet is available for download at wallet.blockstack.org.

What is a public Stacks wallet address?

During the initial grant process, investors submitted a public Stacks wallet address to Blockstack. This is a string of letters and numbers starting with an ‘SP’ or SM’, for example SP017AUV5YRM7HT3TSQXJF7FCCYXETAB276BQ6XY is a wallet address.

If you purchased Stacks tokens through CoinList, you can find your address at CoinList. If you submitted your Stacks address directly to Blockstack, you can either use the “Restore from Seed Phrase” feature on the Stacks wallet or contact us at [email protected] for help.

How do I get help from a person?

For questions or help regarding the Stacks token, you can contact us at [email protected].
