# Coretime on Paseo steps: 1. launch coretime chain 2. assign slots to coretime chain 3. check weights for XCMs in the migration 4. check config for amount of availablity cores, etc 5. 2 validators per parachains -> maximize pov 6. then we can trigger the migration --- manage on demand cores on demand are served directly from the relay. bulk cores are served through the coretime chain via sales. permissionless bulk sales. --- Kusama coretime config calls: https://kusama.subscan.io/referenda_v2/375 `0x32000a000000e0c40000e0c40000b013000000ca9a3b0080c3c901b0130000` ![image](https://hackmd.io/_uploads/BJWlnA1QC.png) `0x32123400` ![image](https://hackmd.io/_uploads/H1PE2R1XR.png) `0x320104ffffffffffffffffffff01` ![image](https://hackmd.io/_uploads/rybI20y70.png) `0x3204005039278c04000000000000000000003400` ![image](https://hackmd.io/_uploads/rkI9h01m0.png) ## Set leases for parachains - postmortem - https://forum.polkadot.network/t/kusama-v1-2-0-coretime-migration-xcm-failure-a-postmortem/7536
