Career
In 1987, Haber joined Bell Communications Research (Bellcore) as a research scientist. In 1989, Haber met W. Scott Stornetta, his future scientific partner and collaborator, when Stornetta joined Bellcore. In 1994, Haber and Stornetta co-founded Surety Technologies, a spinoff of Bellcore. In 1995, Surety’s offering constituted the first commercial deployment of a blockchain and is currently the oldest continuously running blockchain.
In 2002, Haber joined HP Labs as a research scientist in the Princeton office, working there for 15 years on cryptography and security related problems.
Haber currently serves as a member of the advisory board for Kadena, a hybrid blockchain platform.
Contributions
Haber's research during his time at Bellcore, along with W. Scott Stornetta, is widely considered to be the foundation for Bitcoin and other digital currencies. Haber and Stornetta are the most cited authors in Satoshi Nakamoto’s original Bitcoin white paper, of the eight citations, three reference their work.
Their 1991 paper "How to Time-Stamp a Digital Document” is where they first describe a system now known as a "blockchain". In this study, Haber and Stornetta sought to create mechanisms to create digital time stamps, offering a solution for maintaining the integrity of digital records and ensuring that they could not be modified or manipulated.
In 1992, Haber, Stornetta, and Dave Bayer incorporated Merkle trees into their design, improving its efficiency by allowing many document certificates to be collected into one block.
In 2018, Haber joined Kadena as an advisor.
