Method GenerateBlock

protocol/block.go:39–51

GenerateBlock generates a valid, but unsigned, candidate block from the current pending transaction pool. It returns the new block and a snapshot of what the state snapshot is if the block is applied. After generating the block, the pending transaction pool will be empty.

(ctx context.Context, timestampMS uint64, txs []*bc.CommitmentsTx)

// After generating the block, the pending transaction pool will be
// empty.

	err := c.bb.Start(c.State(), timestampMS)
	if err != nil {

// CommitAppliedBlock takes a block, commits it to persistent storage and
// sets c's state. Unlike CommitBlock, it accepts an already applied
