Toward Mobile Distributed Ledgers

Boi Faltings, Sujit Prakash Gujar, Dimitrios Chatzopoulos, Anurag Jain

Advances in mobile computing have paved the way for new types of distributed applications that can be executed solely by mobile devices on Device-to-Device (D2D) ecosystems (e.g., crowdsensing). Sophisticated applications, like cryptocurrencies, need distr ...

La Havane en mouvement: d'une rive à l'autre (Cuba)

Marcel Perrin, Philippe Bechet

En 2009, Cuba fêtait le cinquantième anniversaire de la révolution qui, bon gré mal gré, a résisté à toutes les tempêtes économiques et politiques. En dépit de cette longévité héroïque, il semblerait que l'île soit à la croisée des chemins, comme en témoig ...

Mapping biological ideas: Concept maps as knowledge integration tools for evolution education

Beat Adrian Schwendimann

Many students leave school with a fragmented understanding of biology that does not allow them to connect their ideas to their everyday lives (Wandersee, 1989; Mintzes, Wandersee, & Novak, 1998; Mintzes, Wandersee, & Novak, 2000a). Understanding evolution ...

Semi-passive replication and Lazy Consensus

André Schiper, Xavier Défago

This paper presents two main contributions: semi-passive replication and Lazy Consensus. The former is a replication technique with parsimonious processing. It is based on the latter; a variant of Consensus allowing the lazy evaluation of proposed values. ...

Specification of Replication Techniques, Semi-Passive Replication, and Lazy consensus*

André Schiper, Xavier Défago

This paper brings the following three main contributions: a hierarchy of specifications for replication techniques, semi-passive replication, and Lazy Consensus. Based on the definition of the Generic Replication problem, we difine two families of replicat ...

Agreement-related problems

Xavier Défago

Agreement problems constitute a fundamental class of problems in the context of distributed systems. All agreement problems follow a common pattern: all processes must agree on some common decision, the nature of which depends on the specific problem. This ...

Semi-Passive Replication

André Schiper, Xavier Défago, Nicoleta Sergent

This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring agreement on a primary (usually done using a membership service). Passive replicati ...
