Functions

func CalcCreateQuota

func CalcCreateQuota(fee *big.Int) uint64

func CalcPoWDifficulty

func CalcPoWDifficulty(quotaRequired uint64) *big.Int

func CalcQuota

func CalcQuota(db quotaDb, addr types.Address, pledgeAmount *big.Int, difficulty *big.Int) (quotaTotal uint64, quotaAddition uint64, err error)

quotaInit = quotaLimitForAccount * (1 - 2/(1 + e**(fDifficulty * difficulty + fPledge * snapshotHeightGap * pledgeAmount)))

• quota used by prevBlock referring to the same snapshot hash

quotaAddition = quotaLimitForAccount * (1 - 2/(1 + e**(fDifficulty * difficulty + fPledge * snapshotHeightGap * pledgeAmount)))

• quotaLimitForAccount * (1 - 2/(1 + e**(fPledge * snapshotHeightGap * pledgeAmount)))

snapshotHeightGap is limit to 1 day e**(fDifficulty * difficulty + fPledge * snapshotHeightGap * pledgeAmount) is discrete to reduce computation complexity quotaLimitForAccount is within a range decided by net congestion and net capacity user account gets extra quota to send or receive a transaction if calc PoW, extra quota is decided by difficulty contract account only gets quota via pledge user account genesis block(a receive block) must calculate a PoW to get quota

func CalcQuotaV2

func CalcQuotaV2(db quotaDb, addr types.Address, pledgeAmount *big.Int, difficulty *big.Int) (uint64, uint64, error)

func CanPoW

func CanPoW(db quotaDb, addr types.Address) bool

func CheckPoWLimit

func CheckPoWLimit(db quotaDb) (bool, error)

A single account is limited to send 10 tx with PoW in one day

func GetPledgeQuota

func GetPledgeQuota(db quotaDb, beneficial types.Address, pledgeAmount *big.Int) (uint64, error)

func InitQuotaConfig

func InitQuotaConfig(isTestParam bool)

func IsPoW

func IsPoW(nonce []byte) bool
