Abstract of Edsko’s Talk:

A cryptocurrency wallet is the primary means by which end users from private individuals to large exchange nodes interact with a blockchain. Its primary function is to keep track of the user's unspent outputs and enable them to submit new transactions into the network. As part of the redesign of the Cardano wallet we have written a detailed mathematical specification (available at ) , which we use for development and testing. In addition, we have done extensive research into "coin selection", the process of choosing unspent outputs from the user's wallet to fulfill a payment request. In this presentation we will give a high-level description of both of these strands of work and provide an opportunity to ask questions.

Abstract: Bernardo's Talk:

In this talk, Dr. Bernardo David introduces Ouroboros, the first blockchain protocol based on proof-of-stake with rigorous security guarantees. Ouroboros is currently used by the Cardano project blockchain.

Bernardo also walks us through the Ouroboros praos protocol, which improves on the efficiency of Ouroboros and is scheduled to be deployed in the next versions of the Cardano project. He will highlight the main techniques developed in the process of designing these protocols, which find applications in the design and security analysis of other PoS protocols.
