  • Solving the Scalability Trilemma
    by Emre Tekisalp
    2020-02-25
    Blockchain architectures today are very inefficient at being both scalable and decentralized, a challenge widely referred to as the scalability trilemma. In this piece, I propose a new mental model called ScaDe (Scalability-per-unit-of-Decentralization) that helps the industry design better blockchains.

  • Why SNARKs Are The Technology of the Coming Decade
    by Pranay Mohan
    2020-01-14
    What if we could, without trust, interact with other parties, and be assured through cryptography that our data would never be leaked? This is where zk-SNARKs come in. In the same way that Bitcoin was a call to action around reasserting our financial ownership, SNARKs in the same vein will help us assert our computational ownership.
