# HIO Content Planning for Logos | Q2 2023
`Examples: see Ingonyama, Risc0, ZK Whiteboard videos on YouTube as inspiration for content format, digestibility and duration`

## Nomos
### **Video Series on Consensus**
*Interview w/ Moh and Alvaro*
3 short videos 15 min a piece per question extracted from a 45 min video that includes all of the questions below for each H3 header.
#### **Carnot Consensus** (45 min)
- What is Carnot consensus? (15 min)
- How does it differ from the others? (15 min)
- What are the pros/cons of it? (15 min)

#### **Commitee Selection and Security** (45 min)
*Interview w/ Alexander*
3 short videos 15 min a piece extracted from a 45 min video to explain each of the two papers and math to lay people starting from first principles:
- Math primer of primitives necesssary to learn in order to understand the analysis (15 min)
- Analysis of the committee formation security and requirements for Carnot (15 min)
- Framework of analysis for Avalanche family of consensus algorithms (15 min)

## Codex

Can do a single 15 min video per each of Codex's features similar to the content outlined in the blog post

#### **Data Durability** (1 hour)
*Interview w/ Dmitriy*
15 min. per segment with a single one hour video encompassing this entire concept.
- What is decentralized storage? (15 min)
- Why do we need it vs centralized storage? (15 min)
- What are existing projects that exist in this space? (15 min)
- How does Codex differ in it's approach to providing a new decentralized storage solution? (15 min)
- High-level answering of the question of "What is Data Durability?" which consists of a method to check data integrity, data retrieval, and repair.

- Discuss data-sharding
- How is the block data protected against erasures and attacks?
- Discuss 2D RS encoding and KZG committments
- How is sampling implemented and how much we need to sample?
