New post on ! Using Portal network protocol for history-expiry By: - morph-dev 🔗 Highlights: - The Finalized Chain History subnetwork is designed to provide decentralized storage for finalized historical Ethereum data. - Nodes that are Execution Layer clients will store all historical headers locally, while others will need a method to obtain block headers for verification. - The content id derivation function is crucial for evenly distributing content across the network and allows for future batch requests. - The subnetwork supports standard protocol messages like Ping, FindNodes, and FindContent, which facilitate communication between nodes. - Future improvements may include better network support and the ability to perform range queries, enhancing the efficiency of data retrieval. ELI5: This research introduces a new way to store historical Ethereum data using a special network protocol called the Portal wire protocol. It allows nodes (computers in the network) to keep track of past transactions and blocks in a decentralized manner, making it easier for them to verify and access this information.
