I'm currently working on headers-first sync, which I believe is generally very useful (it fixes tons of edge-cases block synchronization currently experiences), but it's also a first step towards SPV mode. So headers-first sync means you first synchronize just the headers, and then, when you already know (or have strong evidence for a guess on) the best chain, start requesting blocks along that best chain - potentially in parallel from different peers. SPV mode is basically headers-first sync, but never do the full block sync step, and replace it with a bloom/birthday/...-based fetching of blocks interesting to the associated wallets. In SPV you'll also need to disable the mempool though, and there will be more small changes, but I think the separate headers-sync phase will be most of the work. -- Pieter ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
