var PrefixDBCacheSize = 0

PrefixDBCacheSize is the size of the cache for the MutableTree IAVL databases

Functions

func AddTx 

func AddTx(vtx *models.Tx, txBytes, signature []byte, state *State,
	txID [32]byte, commit bool) ([]byte, error)

AddTx check the validity of a transaction and adds it to the state if commit=true

func AdminTxCheck 

func AdminTxCheck(vtx *models.Tx, txBytes, signature []byte, state *State) error

AdminTxCheck is an abstraction of ABCI checkTx for an admin transaction

func AminoKeys 

func AminoKeys(key crypto25519.PrivKey) (private, public []byte, err error)

AminoKeys is a helper function that transforms a standard EDDSA key into Tendermint like amino format useful for creating genesis files.

func CheckProof 

func CheckProof(proof *models.Proof, censusOrigin models.CensusOrigin, censusRoot, processID, key []byte) (bool, *big.Int, error)

CheckProof checks the validity of a census proof (depending on the origin). key is the data to be proof in behalf the censusRoot. In case of weighted proof, this function will return the weight as second parameter.

func GenerateNullifier 

func GenerateNullifier(address ethcommon.Address, processID []byte) []byte

GenerateNullifier generates the nullifier of a vote (hash(address+processId))

func NewGenesis 

func NewGenesis(cfg *config.VochainCfg, chainID string, consensusParams *types.ConsensusParams, validators []privval.FilePV, oracles []string) ([]byte, error)

type TenderLogger 

type TenderLogger struct {

	Disabled bool
	// contains filtered or unexported fields

TenderLogger implements tendermint's Logger interface, with a couple of modifications.

First, it routes the logs to go-dvote's logger, so that we don't end up with two loggers writing directly to stdout or stderr.

Second, because we generally don't care about tendermint errors such as failures to connect to peers, we route all log levels to our debug level. They will only surface if dvote's log level is "debug".
