Leader-based consensus algorithms are fast and efficient under normal conditions, but lack
robustness to adverse conditions due to their reliance on timeouts for liveness. We present …

Distributed ledger technologies, such as blockchain systems, have in recent years emerged
as promising platforms for machine-to-machine commerce and other forms of multi …

It has recently been shown that, contrarily to a common belief, money transfer in the
presence of faulty (Byzantine) processes does not require strong agreement such as …

In this paper, we consider the Byzantine reliable broadcast problem on authenticated and
partially connected networks. The state-of-the-art method to solve this problem consists in …

We introduce Rabia, a simple and high performance framework for implementing state-
machine replication (SMR) within a datacenter. The main innovation of Rabia is in using …

Causal broadcast is a communication abstraction built on top of point-to-point send/receive
networks that ensures that any two messages whose broadcasts are causally related (as …

Prototy** and implementing distributed algorithms, particularly those that address
challenges related with fault-tolerance and dependability, is a time consuming task. This is …

In today's world, everyone wants a good profit with a tiny investment and distributed
computing is a boon for this purpose. Cloud computing, fog computing, and the Internet of …

Blockchains are distributed secure ledgers to which transactions are issued continuously
and each block of transactions is tightly coupled to its predecessors. Permissioned …
