Blockchain is promising to do for value what the internet has done for information. Blockchain technology enables the facilitation of trust in an environment where individuals can securely reach consensus on a transaction’s validity, regardless of whether or not said individuals have a pre-existing relationship. For these reasons, blockchain is the technology best poised to […]
What are the properties of PBFT? Can cryptocurrencies be implemented on PBFT? (Part 2 on Practical Byzantine Fault Tolerence)
Foreword In the previous article, we provided an introduction to the process by which PBFT works. But now, how do we know whether it is really efficient (and effective)? The two main concepts that shall be studied in order to answer this question are safety and liveness. How does PBFT ensure that both safety and […]
What is PBFT and what are its main characteristics? Can cryptocurrencies be implemented on PBFT?
In this article, we want to introduce a long-lasting classic: Practical Byzantine Fault Tolerance, or PBFT for short. PBFT has already been in existence for over 20 years now, and its birth traces back to the well-known consensus problem in decentralized systems commonly known as the Byzantine Generals Problem. PBFT is not a consensus protocol […]
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 […]
“It is fair to say that today’s Internet, absent a native identity layer, is based on a patchwork of identity one-offs.” – Kim Cameron, former Architect of Identity at Microsoft The right to identity is a fundamental human right that exists from the moment we are born and lasts for life. This right is recognized […]
