Zcash Engineering Office Hours #4: Memo Bundles and On-Chain Storage Considerations

​Memo Bundles (ZIP-231) propose a way to make Zcash memos more expressive and scalable, reducing the amount of required on-chain storage while also supporting richer application workflows and preserving core privacy properties.

​In this Office Hours, Kris Nuttycombe will walk through what Memo Bundles are, why they matter, and what they enable for wallets and app developers.

​We’ll also zoom out to the economics of “on-chain storage” more broadly: what data belongs on-chain, how long it should live there, how (and when) we can prune history, and how we might think about charging for block space over both the short and long term.
