## Description

This talk with introduce a decentralized way for all users to access Ethereum in a resource efficient way, but still maintain full access to the state. The video discusses the challenges of accessing Ethereum in a decentralized manner due to the high requirements for running a full node, such as significant storage, constant operation, and technical knowledge. The speaker introduces the portal network as a solution that allows nodes to store only the data they need, reducing the burden on individual nodes while maintaining access to necessary information. The portal network operates on a peer-to-peer protocol and utilizes distributed hash tables for data storage, ensuring that data remains accessible and isn't flushed from the network. The incentive model for the portal network is based on low participation costs with high data value. The speaker outlines various networks within the portal framework, including ones dedicated to history, state, and transactions, and explains how data validation works using accumulators and Merkle-Patricia trees.

The timeline for launching different components of the portal network is discussed, with some parts already operational. Portal integration could significantly reduce storage requirements for running a validator or full node. The speaker mentions upcoming improvements like vercal tries and an EIP that would allow offloading old blocks. They also highlight that participation in the portal network requires minimal resources.

Various teams are building clients compatible with the portal network, including an Ethereum Foundation team working on a Rust client called Trim. The video concludes with an invitation to learn
