We provide: underlying data structure : optimized implementation of
rank-based skip list(together with authenticated and ordinary skip lists) as a library.
Optimized proof mechanism between client and server (prototype)
What is next: Optimizations with parallel I/O and cryptographic
computation Implementation on mobile devices Energy consumption measurements and application of
energy-efficiency methodologies
