New York-based blockchain company tZERO, which is a majority-owned subsidiary of Overstock.com, announced Wednesday that a former in-house attorney at Mastercard has been named the company's chief legal officer.

Alan Konevsky is responsible for overseeing the company's legal, regulatory, public policy and compliance functions. He is the leader of the company's in-house team and reports to tZERO's CEO, Saum Noursalehi. According to Konevsky's LinkedIn profile, he began working at tZERO in November. It was not immediately clear if he is the company's first chief legal officer.

“I am thrilled to join the tZERO team at such an exciting juncture in its history, particularly as we are working to launch one of the world's first regulated STO exchanges. I am looking forward to working closely with policymakers, regulators, business partners and other stakeholders in our ecosystem to create more efficient and transparent capital markets with blockchain technology,” Konevsky said in the news release.

Noursalehi said, “Given Alan's vast legal experience, we believe that his insight will be a valuable asset for the problem-solving required to create the next generation of capital markets,” in the release.

The company recently announced that it is prepared to release a Cobalt-backed security token. The Hong Kong based GSR Capital, a private equity firm, retained tZERO to develop a smart contract token that will be used for an upcoming sale of Cobalt, according to the announcement.

According to his LinkedIn profile, Konevsky worked in a variety of roles on the in-house legal team at Mastercard. He served as senior managing counsel of mergers and acquisitions, senior vice president and strategic initiatives counsel and senior vice president and strategic initiatives and technology counsel. He has also worked as a managing director and senior counsel at Goldman Sachs in London. Before going in-house, Konevsky was an associate and special counsel at Sullivan & Cromwell. He graduated from Harvard Law School.

TZERO is a portfolio company of Medici Ventures, which is Overstock.com's blockchain subsidiary, according to the news release. The company was founded in 2014 with the goal of using blockchain technology to make financial processes less reliant on traditional institutional market structures.
