Stellar is an open source, decentralized protocol for digital currency to fiat money transfers which allows cross-border transactions between any pair of currencies.[1] The Stellar protocol is supported by a 501(c)3 nonprofit, the Stellar Development Foundation.[2][3][4]


In 2014, Jed McCaleb, founder of Mt. Gox and co-founder of Ripple, launched the network system Stellar with former lawyer Joyce Kim. Before the official launch, McCaleb formed a website called "Secret Bitcoin Project" seeking alpha testers.[5] The nonprofit Stellar Development Foundation was created in collaboration with Stripe CEO Patrick Collison and the project officially launched that July. Stellar received $3 million in seed funding from Stripe.[6][7] Stellar was released as a decentralized payment network and protocol with a native currency, stellar. At its launch, the network had 100 billion stellars. 25 percent of those would be given to other non-profits working toward financial inclusion.[8][9] Stripe received 2 percent or 2 billion of the initial stellars in return for its seed investment.[10] The cryptocurrency, originally known as stellar, was later called Lumens or XLM.[11] In August 2014, Mercado Bitcoin, the first Brazilian bitcoin exchange, announced it would be using the Stellar network.[12] By January 2015, Stellar had approximately 3 million registered user accounts on its platform and its market cap was almost $15 million.[13]

The Stellar Development Foundation released an upgraded protocol with a new consensus algorithm in April 2015 which went live in November 2015.[14] The new algorithm used SCP, a cryptocurrency protocol created by Stanford professor David Mazières.[15], a for-profit entity of Stellar, launched in May 2017 as the commercial arm of the company.[16] In September 2017, Stellar announced a benefits program, part of its Stellar Partnership Grant Program, which would award partners up to $2 million worth of Lumens for project development. In September 2018, Lightyear Corporation acquired Chain, Inc and the combined company was named Interstellar.[17]

Real-world applications[edit]

In 2015, it was announced that Stellar was releasing an integration into Vumi, the open-sourced messaging platform of the Praekelt Foundation.[18] Vumi uses cellphone talk time as currency using the Stellar protocol.[19] Stellar partnered with cloud-based banking software company Oradian in April 2015 to integrate Stellar into Oradian's banking platform to add microfinance institutions (MFIs) in Nigeria.[20][21]

Deloitte announced its integration with Stellar in 2016 to build a cross-border payments application, Deloitte Digital Bank.[22] In December 2016, it was announced that Stellar's payment network had expanded to include, a mobile payments startup in the Philippines, ICICI Bank in India, African mobile payments firm Flutterwave, and French remittances company Tempo Money Transfer.[23]

In October 2017, Stellar partnered with IBM and KlickEx to facilitate cross-border transactions in the South Pacific region. The cross-border payment system developed by IBM includes partnerships with banks in the area.[24][25]

In December 2017, TechCrunch announced Stellar's partnership with SureRemit, a Nigerian-based non-cash remittances platform.[26]


Stellar is an open-source protocol for exchanging money or tokens using the Stellar Consensus Protocol. The platform's source code is hosted on GitHub.

Servers run a software implementation of the protocol, and use the Internet to connect to and communicate with other Stellar servers. Each server stores a ledger of all the accounts in the network. 3 nodes are operated by the Stellar Development Foundation, in conjunction with 21 other organizations, providing for a total of 66 validator nodes[27]. Transactions among accounts occur not through mining but rather through a consensus process among accounts in quorum slice.[28] The current network fee is 100 stroops, equivalent to 0.00001 XLM or 1/10,000th of a cent[29].
