Questions tagged [holochain]

Use this tag for all questions related to both the Go-based prototype and the Rust-based official version of Holochain. Additionally tag with `holochain-proto` or `holochain-rust` if you need to be specific.

Holochain is a framework for building peer-to-peer, cryptographically secure applications that non-technical users can enjoy. Unlike blockchain smart contracts and dApps, Holochain apps do not use global consensus or leader selection algorithms, tokens, or central ledgers. Each agent interacts directly with agents it cares about, and public data is published to a DHT, where a small number of peer validators (randomly selected based on distance of the data's hash to their node address) notarize it and keep a backup copy. This results in blockchain-level data integrity with Git-level data storage and energy consumption.

Does Holochain do anything to prevent excessive storage use?

If one peer's source chain receives far more events than average, and ends up needing much more storage (and compute) than a typical peer, does the network punish that or mitigate the cost to others, in any way? Is anything for that planned? (As an…
