Paper Title: Multi-Threshold Asynchronous Reliable Broadcast and Consensus.
TLDR:
Most known fault-tolerant distributed protocols provide security guarantees in an all-or- nothing fashion: if up to t parties are corrupted, all security guarantees remain. However, if more than t parties are corrupted, the protocols do not provide any security guarantees.
Multi-threshold protocols (also known as hybrid security) provide different security guarantees depending on the amount of corruption, thereby allowing a graceful degradation of security.
This work considers consensus and reliable broadcast protocols with separate thresholds for validity, consistency and termination, respectively.
For consensus, both variants of (1 − ε)-consensus and almost-surely terminating consensus, where termination is guaranteed with probability (1 − ε) and 1, are considered respectively.
The protocols work without the use of signatures and in the purely asynchronous model without the need to make any timing assumptions.
The contributions give a very complete picture of feasibility and impossibility results.

3. Paper Title: Blockchain, Bitcoin and Stigmergy: An Explanation and a New Perspective for Regulation.
Summary: This essay tries to create a model based on swarm intelligence and stigmergy explaining the “organization without organizer”. This innovative model can be useful to obtain a new framework that accounts for the different dynamics of cryptocurrencies and how regulation could affect different classes of actors.
