Every round can be slightly different and this kind of little bit difference is sort of a protection against certain types of attacks. There are some classes of attacks that the metronol very well is the attacks that try to walk around the number of rounds for example what we call meeting the middle or rebound attack. But ultimately the more rounds you have the more security so if you have like an infinite number of rounds it should be fine unless you have attacks like the slide attack that metronetionUnless you have a structural weakness but then you have a different design paradigm which is what reinforced concrete is doing.
In this week’s episode, Anna and Kobi Gurkan speak with Dmitry Khovratovich, researcher at the Ethereum Foundation, Dusk Network, and ABDK Consulting and JP Aumasson CSO at Taurus. This episode compares symmetric and asymmetric cryptography as well as a deep dive into hash functions. They explore what hash functions are used for, the process of developing and improving hash functions, and what it means for a hash function to be zk friendly.

Anoma is a set of protocols that enable self sovereign coordination.
Anoma's first fractal instance Namada is planned for later in 2022, and it focuses on enabling shielded transfers for any assets, with a few second transaction latency and near zero fees.
