Kernel
Kernel structure
Coinstake kernel it's a virtual structure which created during Proof-of-Stake block validation attempt. This structure exists in database and memory, but not on the network. The kernel parameters are described in the following table.
| Field | Type | sizeof | Description |
|---|---|---|---|
| nStakeModifier | unsigned long int | 8 | Deterministic modifier, scrambles computation to make it very difficult to precompute future Proof-of-Stake at the time of the coin's confirmation. |
| nTimeBlockFrom | unsigned int | 4 | Timestamp for block which provided previous transaction, prevent nodes from guessing a good timestamp to generate transaction for future advantage. |
| nTxPrevOffset | unsigned int | 4 | Offset of previous transaction inside the block, used to reduce the chance of nodes generating kernel coinstake at the same time. |
| nTxPrevTime | unsigned int | 4 | Timestamp of previous transaction, used to reduce the chance of nodes generating coinstake kernel at the same time. |
| nPrevoutNum | unsigned int | 4 | Output number of previous transaction, used to reduce the chance of nodes generating coinstake kernel at the same time. |
| nTimeTx | unsigned int | 4 | Current timestamp |
