I’m writing a small blog post about the applicability of PoW fraud proofs towards improving light client security, while retaining the low resource usage of such clients. The post summarizes my experiments with a lightweight node implementation that I’m working on, Floresta, and how we would ship this idea into clients that work on contained devices, like smartphones.
The idea is still very early on, and I would love to see some feedbacks on the idea and general design. There are some open problems, specially related to DoS, any solution to this would also be much appreciated.
