BTQ in Taiwan!
BTQ is happy to announce that the company has received government approval for the establishment of a branch office in Taiwan. While BTQ initially set up a representative office in 2021, our Taipei operations have grown considerably since then, and the transition to a branch office structure is the logical next step for the company. BTQ now has a bustling office in the heart of Taipei’s Zhongzheng district, and registering as a branch office of the parent company has expanded the scope of available business activities, which were somewhat more constrained for our previous representative office. By setting up a branch office in Taipei, BTQ has deepened its commitment to building next generation encryption technology within Taiwan’s world-class semiconductor ecosystem, with an ever-growing IP portfolio generated by Taiwan’s brightest talents in the field of post-quantum cryptography. With additional offices in Australia and Liechtenstein and collaborations with high-level research institutions including Taiwan’s ITRI, BTQ is now poised to take the lead in bringing quantum secure technology to the global market.
Blockchain security in the quantum era
Blockchain public-key infrastructure is built on top of two mathematical problems: integer factorization and discrete logarithm problems, both of which are vulnerable to quantum attacks. This essay describes some of the options and challenges in light of the quantum threat.
Keelung - A toolkit for fast, private and secure applications
We are excited to announce Keelung, a zero-knowledge cryptography development toolkit for fast, private and secure applications. Keelung makes it simple to build zero-knowledge proofs (ZKPs) for your application regardless of the business logic or use case. Zero-knowledge cryptography has a bright future, and we want to make it easy for teams to build and ship.
