Most digital privacy advocates take user consent as the go to solution to avoid Big Brother. But does that stand the test of reality?

This discussion stems from a thought provoking tweet, to say the least. “Maybe consent should have *no* place in privacy law”.


And how to solve it, in theory and in practice

Identity systems have traditionally been hierarchical directories. In organizations, central administrators define the rights that each user (or group of users) has on the system. And so, they need to know who the user is.

One the internet, nobody knows you’re a dog

More than a licence, we need to commit to a sustainable digital infrastructure.

A (very) brief history of open software movements

Both free software and opensource have had tremendous success.

Proof of stake (PoS) is a hot topic in the blockchain community. But will it work out as expected?

A short primer on consensus history

Why would we need Proof of Stake consensus algorithm, instead of Proof of Work? In short, the answer is two-fold : scalability and resource-efficiency.
