Our Journey
2012-2016: Hashgraph

In 2012, Dr. Leemon Baird begins to work on solving how to achieve distributed consensus at scale.

In 2015, Dr. Baird develops the breakthrough innovation now called hashgraph, and knew it had the potential to be revolutionary. A few months later, Dr. Baird and his longtime friend and business partner, Mance Harmon, form Swirlds, Inc. (a portmanteau of “shared worlds”) to develop proofs of concept and to commercialize hashgraph for private implementations. Their larger and longer-term vision is to use hashgraph to enable a truly decentralized, fast, fair, and secure public distributed ledger that could achieve mainstream adoption and serve as the “trust layer of the Internet”.

They focus on proving the benefit and value of the hashgraph data structure and consensus algorithm for enterprise use. The Hashgraph whitepaper is published on May 31, 2016, and hashgraph is selected over more established solutions for use in private network pilots. The time comes to turn focus to creating a public distributed ledger powered by hashgraph.

2017-2018: Formation of Hedera
Q1 – Q2 2017

Swirlds raises its seed investment round. Funds from that financing are used to bootstrap the formation of Hedera. Mance and Leemon spent time developing the main governance philosophy, conceptualizing the structure and role of the council and its governing members, determining the licensing terms for use of hashgraph for a public implementation, developing the strategy to prevent forking, and teaching people about how hashgraph differs from – and offers key advantages over – blockchain.

Q3 2017

Mance and Leemon begin to grow the project. Over the summer, they meet Andrew Masanto, Founding CMO, who helps bootstrap the company, providing key early contributions and introducing Mance and Leemon to a number of Hedera’s initial team members (including executives Jordan Fried, Natalie Grunfeld Furman, and Tom Trowbridge).

Founding team is brought onboard, including executives Jordan Fried (SVP, Business Development) who joins in August 2017 to lead Hedera’s global business development and Council recruitment and Natalie Grunfeld Furman (General Counsel), who joins in September 2017 to develop Hedera’s legal and regulatory strategy. Initial business strategy meeting with potential advisors and investors held in NYC.

Hashgraph Consortium, LLC is created as a Delaware limited liability company. Hashgraph technology is displayed publicly to the world for the first time at TechCrunch Disrupt in San Francisco, CA.

Q4 2017

Additional team members and executives are brought onboard, including Tom Trowbridge (former President) to lead Hedera’s financing and assist with recruiting initial Council members, and Edgar Seah (Head of APAC), who runs business development in Asia and assists with Council recruitment. First Letters of Intent are signed by potential Council members.

Q1 2018

First formal meeting of the executive team and advisors is held. Hiring continues. “Hedera Hashgraph” is selected as the brand and company name, and the HBAR logo is designed. Additional Letters of Intent are signed by potential Council members.

Hedera launch event is held on March 13 in NYC, drawing 1,000 people live and more than 21,000 livestream viewers. The event unveils Leemon and Mance’s vision for a public network – a network to be built on the patented hashgraph algorithm, governed by a Council of 39 global enterprises, and guaranteed not to fork – to the general public for the first time. HederaHashgraph.com goes live and the Hedera whitepaper is published.

Q2 2018

Hedera continues to educate the market and developers about hashgraph technology. Additional LOIs signed. Company name is formally changed to Hedera Hashgraph, LLC. Multi-member LLC Agreement, the document governing the Hedera Council, is drafted. Work continues to prepare for launch of Hedera mainnet and minting of hbars.

Q3 2018

Hedera mainnet goes live on August 24, 2018. 50 billion hbars are minted. The first meeting of potential Council members is convened to review the Hedera LLC Agreement and details of Council membership.

Q4 2018

Hedera18, Hedera’s first developer conference and global hackathon, occurs at eight locations around the world. Hedera launches mainnet early access and the phase one community testing programs, giving developers and users the ability to test the network for the first time. COQ Proof conducted by Carnegie Mellon confirms hashgraph algorithm is Asynchronous Byzantine Fault Tolerant (to date, the only algorithm in the public market to achieve this gold standard of security).

2019: Governing Council & Open Access
Q1 2019

The first Hedera Governing Council members are announced, and the first Governing Council meeting happens in Seoul, Korea, alongside the first Hedera Annual Assembly, hosted in Seoul.

Q2 2019

Additional Governing Council members sign the LLC Agreement, and the second Governing Council meeting happens in New York City. Phase two of the Community Testing Program begins, opening up the Hedera network to further testing from interested developers and users.

Q3 2019

Hedera's Mirror Node software enters alpha on August 29th, 2019. Mirror nodes provide a way to store and cost-effectively query historical data from the public ledger, while minimizing the use of Hedera network resources.

The Hedera mainnet (beta) is made openly accessible on September 16th, 2019. Anyone can build and deploy their applications on the Hedera mainnet and create accounts for themselves and/or end users of their applications.

Hedera continues to support integrations with third-party software that support the use of the mainnet and hbar including wallet software, exchange services, custody services, and more.
