// Blocks, blocks will have transactions.
// Transactions/contracts are updated in goroutines
// Each contract should send a message on a channel with usage statistics
// The statics can be used for fee calculation within the block update method
// Statistics{transaction, /* integers */ normal_ops, store_load, extro_balance, crypto, steps}
// The block updater will wait for all goroutines to be finished and update the block accordingly
// 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
