The Future is a Safe And Dark Web. This Is What It Will Look Like:

This article first appeared on Nesta.org.uk as one of the top finalists in The Decentralised Future Prize essay competition. “Mass surveillance by governments and corporations will become normal and expected this decade and people will increasingly turn to new products and services to protect themselves from surveillance. The biggest consumer technology successes of this decade […]

Creating Unpredictability: Random Number Generator Use Cases

“Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin. For, as has been pointed out several times, there is no such thing as a random number — there are only methods to produce random numbers.” – John Von Neumann Random number generators (RNGs) are a crucial part of many […]

Scalability Magic: BLS Signatures

Blockchain Scalability Blockchain scalability has likely been one of the most researched topics in crypto environments in the past few years. Regardless of their involvement in the crypto world, almost everyone at this stage is aware of the ridiculously low amount of transactions processed per second of Bitcoin with respect to VISA for example. To […]

Provable Randomness: How To Test RNGs

And The Future of RNG Analysis

How do you know if something is really random? When testing Random Number Generators (RNGs) for randomness you quickly run into the “is that really random” dilemma. As pattern seeking creatures, we naturally look for patterns on an ongoing basis. Like many things, randomness varies. Most of the time, pseudo-random numbers generators (PRNGs) are basically […]

Introduction to Self-Sovereign Identity

What is Self-Sovereign Identity (SSI)? How to implement SSI on top of blockchain?

Foreword Everyone had the experience of answering the question “Who are you?”. When you were asked, how did you introduce yourself? Did you give your name and title? Identity card number? Or the registration number of an event? When we are trying to answer “who are you”, we are also defining our identity. Identity can […]

Infrastructure Threats to P2P Networks

Internet Backbone It’s fair to say that most people without a deep understanding of networking probably consider the internet to be a globally decentralized network, which is a reasonable assumption though incorrect. Thousands of internet service providers and telephone companies globally all vying to offer connectivity to householders and end-users give the illusion of a […]

Security in Chaos and Entropy

True Random Number Generators

In many systems, “random” numbers are supplied by algorithms called pseudo-random number generators (PRNGs) or deterministic random bit generators (DRBGs). These algorithms generate long sequences of seemingly random bits that are based on a secret initial value called a seed, and other possible inputs [1]. This approach creates the illusion of unpredictability. In practice, however, […]

A Brief History of Random (In)security

Random Number Generator Hacks and Exploits

Most software and operating systems use random numbers for security processes. And because software is often built with cost and speed in mind, developers tend to use pseudo-random number generators (PRNGs) to create cryptographic keys and other system encryptions. PRNGs are algorithms that use mathematical formulas or precalculated tables to produce sequences of seemingly random […]

Privacy, Blockchain and Onion Routing

Why is Privacy Important? Is Blockchain Anonymous? How can Onion Routing Improve Blockchain?

Foreword Since blockchain was introduced in 2008, it has been regarded as Web 3.0 and is expected to further bring about a great leap in finance and governance for mankind. The blockchain may become an infrastructure like the World Wide Web. If we have begun to protect our privacy on the Internet, then we should […]

Why Decentralized ID (DID) Matters to our Self-Sovereign Future

Decentralized IDs have the potential to help internet users around the world wrest back control of their data from the corporations that presently control it.  

Why Decentralized IDs matter Decentralized Identifiers (DIDs) have recently gained more attention for being one of blockchain’s most exciting use cases, and the hype is well founded. In concept, DIDs aim to use cutting-edge cryptography and unique identifiers to enable users to validate themselves online, while still dictating when and how that identity data is […]
