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))

type TrustedCheckpoint added in v1.8.20 

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

}

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.
