// Blocks, blocks will have transactions.

// Transactions/contracts are updated in goroutines

// The statics can be used for fee calculation within the block update method
|

// Statistics{transaction, /* integers */ normal_ops, store_load, extro_balance, crypto, steps}

|
// in one go and should use minimal IO overhead.
|
|
// The actual block updating will happen within a goroutine as well so normal operation may continue
