Our paper "Improving Authenticated Dynamic Dictionaries, with Applications to Cryptocurrencies" will appear at the Financial Cryptography 2017 conference in Malta in April. It was also presented at the Real World Crypto 2017 conference in New York and I highly recommend watching the impressive presentation from Leonid Reyzin, professor of computer science at Boston University…

Mathematicians with a curiosity about the algorithms behind blockchain came to hear Aggelos Kiayias speak at Oxford university’s Mathematical Institute on Wednesday. Professor Kiayias, Chief Scientist at IOHK, had been invited to the university to give a talk on his work on Ouroboros, a provably secure Proof-of-Stake algorithm for blockchain.

Winter School on blockchain

The year got off to an invigorating start for IOHK when a team of its researchers arrived in a chilly Shanghai for the first ever Winter School on cryptocurrency and blockchain technologies.

The 121-year-old Jiao Tong University – one of China’s leading institutions with alumni including the former president of China Jiang Zemin – hosted the conference in step with a rising interest in blockchain in China, including in its capital of commerce, Shanghai. The winter school follows a similar event in Greece last year, the first Bitcoin Summer School, run by the International Association for Cryptologic Research.

The main hall at the university’s technology building was packed for the three-day event, with a cast of renowned cryptographers on the stage, including IOHK chief scientist Aggelos Kiayias. Professor Kiayias presented a double session on his work on proving the security of blockchain protocols. Jonathan Katz from the University of Maryland spoke on game theory, as…

On a frosty Friday morning in Switzerland’s commercial centre of Zurich, an audience arrived early at the university to learn about the emerging field of smart contracts in a presentation given by Charles Hoskinson. A completely new way of quantifying concepts like trust, reputation and ambiguity, smart contracts are a digital legal system – a computer protocol that facilitates…

The Grothendieck Team

Hi everyone, it's my pleasure to officially announce the new team known as The Grothendieck Team! The team has been named after Alexander Grothendieck, a German-born French mathematician who became a leading figure in the creation of modern algebraic geometry. They have been committed to Ethereum Classic by IOHK in order to build a Scala client for ETC based on IOHK's …
