Kaleidoscope – a cryptographic protocol

Poker is arguably one of the most popular card games in the world, both in casinos and on the internet. Online poker has become increasingly popular after a boom in the early 2000s, fueling a growing market with revenues estimated in the tens of billions of dollars. However, the current model of online gambling forces users to blindly trust the online casinos, who could easily…

A solution for scalable randomness

It is well known that randomness is a fundamental resource for secure cryptographic schemes. All common encryption and authentication schemes are only as secure as their randomness sources are good. Using a poor randomness source can basically render insecure every cryptographic scheme that would otherwise be secure. In many cases, it is sufficient to have a trustworthy local…

Proof-of-Stake Protocol - IOHK

This is the regular seminar of the Input Output and Tokyo Tech/Tanaka Laboratory members. The topic this time is the Proof-of-Stake Protocol designed by Aggelos Kiayias, Ioannis Konstantinou, Alexander Russel, Bernardo David and Roman Oliynykov.

Bernardo, the presenter, divided the talk in two parts: the first reviews main topics in Cryptography which would help the viewer to understand the presentation and the protocol itself. Whereas the second is about the protocol itself.

First Part - Cryptography background

  • Commitments
  • Coin Tossing/Guaranteed Output Delivery
  • Verifiable Secret Sharing

Second Part - Proof-of-Stake…
