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
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
