Secure Kademlia Library

DAS Networking in Ethereum requires lots of small blob samples to be placed in a distributed network where arbitrary nodes can query “the network” to make sure these samples are available.

Development Update #10

Before we get to the normal Dev Update... Over the past 4 months I dove deep into Danksharding, Ethereum Networking, and then p2p networking in rust + building out a discv5 overlay simulation. A few days back, I read a few "big-picture" Ethereum developer documents: Network Layer and Data Availability. Somewhere along the journey I lost the thread. I was building this Data Availability Sampling p2p network simulation without understanding the "why" behind it all.

EPF Final Update

Tackling the DAS Networking problem requires a p2p network that has low-latency, is privacy preserving and is sybil-resistant. The idea behind Model DAS is to measure benchmarks on DAS querying via Secure Kademlia DHT Discv5 overlay network. This Secure K-DHT is a seperate validator-only overlay network that leverages validators' incentive alignment to create a robust DAS network if the primary network were to come under attack. Status Report The original vision for Model DAS didn't entail creating a new DAS simulation; the idea was just to extend the functionality of another. But seeing that I was new to gerenal networking concepts and the Rust programming language, it quickly became aparent that building a simplified version of DAS Prototype was an escential prerequisite to executing the vision behind Model DAS.

Summary of DAS Playground (WIP)

Within this document I talk about specific concepts within DAS-Playground.   Motivation Required Reading: What is Danksharding? A TLDR on Required Reading: Ethereum's rollup-centric roadmap requires extra blob data to be placed on chain. The more blob data that can be placed on chain, the more Ethereum can scale. But... Extra data = extra cost to run a node = reduced decentralization =    : (
