* Initial draft of brain dump of chandler. Nothing yet set in stone. * Will most likely move the storage of all structs to a more “column” oriented approach. Such that, small updates like incrementing the total satoshi sent don’t result in the entire struct being serialized and written. * Some skeleton structs for other possible data we might want to store are also included. * Seem valuable to record as much data as possible for record keeping, visualization, debugging, etc. Will need to set up a time+space+dirty cache to ensure performance isn’t impacted too much.
