Metadisk: Blockchain-Based Decentralized File Storage Application

Storj is an open source software project seeking to prove conceptually that cloud storage services can be made decentralized, more secure, and more efficient while providing hard asset backing for sound money. In furtherance of this goal, we propose developing two distinct, interoperable, and interdependent software applications: 1) BitCumulus, a file hosting web application that […]

How to Use Bitcoin to Incentivize Correct Computations

We study a model of incentivizing correct computations in a variety of cryptographic tasks. For each of these tasks we propose a formal model and design protocols satisfying our model’s constraints in a hybrid model where parties have access to special ideal functionalities that enable monetary transactions. We summarize our results: Verifiable computation. We consider […]


SafeCoin is the official coin of, a project that began in Scotland in 2006 to create a distributed internet using user-donated computing resources. Safecoin incentivizes people to contribute data storage resources to the network; as the network grows, it can handle more traffic and resemble the centralized internet used today. Maidsafe stands for Massive […]
