Tiancheng Zie - Full STARK implemention version of SSF Problem: - Want to prove full node consensus - 20k-30k signatures, frequent committee changes - Verify 20k+ BLS signatures in 12 seconds - Their machine can prove 30k signatures in 6 sec - Hardware requirement: - Stable network - Mobile cpu - 16gb ram - Current eth solution divides validator committee into slots where each has a fraction of validators - To reach majority consensus, you need to wait for a lot of slots - At least 20 slots to reach majority vote - several minutes - Most exchanges wait 2 epochs - long compared to block time - Problem: Need to translate signatures as a bitfield in a network - Too congested for the whole network - With this sig scheme you only transfer to the bitfield, can simplify communication between devices -
