Blockstack is a blockchain-based network for decentralized applications[1]. Blockstack provides protocols and software libraries for authentication, storage, and app publishing in a decentralized manner. Blockstack aims to address the centralization at the application-layer of the internet and provides decentralized alternatives to internet's domain name system and public-key infrastructure. Developers have built decentralized apps like word processors and spreadsheets[2], messaging apps[3], business productivity[4], and social networking apps amongst others, using the software.

Blockstack is often described as a new internet, separate from the traditional internet, with a focus on privacy, security, and data ownership[5][6]. Season 5 of the HBO Silicon Valley show partially based their concept of a new decentralized internet on the MaidSafe and Blockstack technologies[7], and Blockstack founders Muneeb Ali and Ryan Shea were technical advisors to the show[8].

Overview[edit | edit source]

Blockstack is being developed by a group of engineers and researchers coming from both industry and academia[9] and is released as open-source. Blockstack's blockchain name system (BNS) is the first implementation of a decentralized DNS system on top of the Bitcoin blockchain.[10] It combines DNS functionality with public key infrastructure and is primarily meant to be used by new blockchain applications. Other systems like Namecoin have implemented decentralized DNS using blockchains earlier by using blockchains other than Bitcoin. Blockstack became operational on the Bitcoin blockchain in September 2015.[11]

In May 2017, at CoinDesk's "Consensus 2017" blockchain conference in New York, Blockstack released a decentralized browser add-on,[12] described as "a kind of Netscape for the decentralized internet, running apps on a plethora of blockchains".[13] The purpose of this add-on is to allow developers to use Blockstack's tools (decentralized identity, storage, and payments) to "create consumer-facing apps". The add-on works with any browser, including Chrome, Safari, and Firefox.[12]

History[edit | edit source]

The project was started by Muneeb Ali and Ryan Shea, in 2013, who met at the Princeton University Computer Science department[14]. While Blockstack is an open-source project, Muneeb and Ryan went through Y Combinator and raised venture capital for a C-corp dedicated to supporting the development of the open-source software[15].

Blockstack Inc. raised $4 million venture capital Series A round from Union Square Ventures, Lux Capital, AngelList founder Naval Ravikant, Digital Currency Group, amongst others and Albert Wenger joined the board.[16]. In September 2017, Blockstack Inc. converted itself into a Public Benefit Corporation, switching from Blockstack Inc. to Blockstack PBC.[17]

In December 2017, Blockstack PBC raised ~$50 million from the sale of a token[18]. Winklevoss Capital, Union Square Ventures, Kevin Rose, Michael Arrington, Foundation Capital, and others participated in this token offering.[19]
