Supply chains show their weaknesses following Avast and NordVPN attacks

Antivirus solution provider Avast and VPN service NordVPN both disclosed data breaches caused by exposed credentials that granted attackers remote access to internal systems. The twin developments come as supply chain attacks — compromising a third-party vendor with a connection to the true target — targeting security-related apps are becoming a common vector to install malware.

Sidechains vs Plasma vs Sharding

Special thanks to Jinglan Wang for review and feedback One question that often comes up is: how exactly is sharding different from sidechains or Plasma? All three architectures seem to involve a hub-and-spoke architecture with a central “main chain” that serves as the consensus backbone of the system, and a set of “child” chains containing actual user-level transactions.

A Guide to 99% Fault Tolerant Consensus

Special thanks to Emin Gun Sirer for review We’ve heard for a long time that it’s possible to achieve consensus with 50% fault tolerance in a synchronous network where messages broadcasted by any honest node are guaranteed to be received by all other honest nodes within some known time period (if an attacker has more than 50%, they can perform a “51% attack”, and there’s an analogue of this for any algorithm of this type).
