DoraHacks organises intensive collaborative programming challenges internationally, having launched with assistance from Tsinghua University in 2014.

DoraHacks, a China-based collaborative computer programming organiser launched with support from Tsinghua University, has raised an undisclosed sum in a round led by bitcoin and computing technology developer Bitmain Technologies.

Other investors in the round were not disclosed.

Founded in 2014, DoraHacks organises collaborative coding conventions known as hackathons in which developers work intensively to achieve challenging objectives within a short space of time. It has so far arranged more than 100 hackathons involving more than 10,000 participants.

DoraHacks will use the capital to sustain its services and infrastructure with the aim of tackling more challenges across various industries at its hackathons. It was established with help from Tsinghua’s Open Wisdom Lab, which aims to foster open and participatory scientific concepts.

DoraHacks has not publicly disclosed details of its earlier funding, but its previous investors reportedly include company founder Zhang Jiannan, TopHacker Group, 8 Decimals Capital and BA Capital.

You Bixue, investment director of Bitmain, said DoraHacks had built a strong rapport with the computer development community by becoming one of the earliest Chinese companies in the space.

DoraHacks also collaborates with blockchain companies, which could give developers more experience in a technology integral to Bitmain’s cryptocurrency business.
