const (
	Wei   = 1
	GWei  = 1e9
	Ether = 1e18
)

These are the multipliers for ether denominations. Example: To get the wei value of an amount in 'gwei', use 

new(big.Int).Mul(value, big.NewInt(params.GWei))

ChainConfig is the core config which determines the blockchain settings.

ChainConfig is stored in the database on a per block basis. This means that any network, identified by its genesis block, can have its own set of configuration options.

Rules wraps ChainConfig and is merely syntactic sugar or can be used for functions that do not have or require information about the block.

Rules is a one time interface meaning that it shouldn't be used in between transition phases.

type TrustedCheckpoint 

type TrustedCheckpoint struct {
	Name         string      `json:"-"`
	SectionIndex uint64      `json:"sectionIndex"`

	CHTRoot      common.Hash `json:"chtRoot"`
	BloomRoot    common.Hash `json:"bloomRoot"`
}

TrustedCheckpoint represents a set of post-processed trie roots (CHT and BloomTrie) associated with the appropriate section index and head hash. It is used to start light syncing from this checkpoint and avoid downloading the entire header chain while still being able to securely access old headers/logs.
