@3b6a3d3b…af3eeb84 already gives this orthogonal perspective. The rendering of the timechain is the orthogonal view on the linear explorer. But at every block height we should be able to rotate the perspective 90° to be looking at that block through the entire chain towards Genesis. If this rendering was coded, it would display the active utxo set at each selectable height bounded by supply of that time. You’d see only the full active surface of utxos and each utxo would be some distance in time from the block of observation. I believe this is would be equivalent to our internal perspective of “space”. The furthest utxo in time if we rendered the spatial distance of time would be the unspent genesis utxo that is the referential anchor to the system. No bit of value would overlap on this surface, value would be bundled in utxos and each would exist at different keys in space at different points in time.
