DepositTrieSubset takes in a full tree and the desired size and returns a subset of the deposit trie.

func DepositsWithBalance added in v1.0.0 

func DepositsWithBalance(balances []uint64) ([]*ethpb.Deposit, *trieutil.SparseMerkleTrie, error)

DepositsWithBalance generates N amount of deposits with the balances taken from the passed in balances array. If an empty array is passed,

func DeterministicDepositTrie added in v0.3.0

func DeterministicDepositsAndKeys(numDeposits uint64) ([]*ethpb.Deposit, []bls.SecretKey, error)

DeterministicDepositsAndKeys returns the entered amount of deposits and secret keys. The deposits are configured such that for deposit n the validator account is key n and the withdrawal account is key n+1. As such, if all secret keys for n validators are required then numDeposits should be n+1.

func DeterministicDepositsAndKeysSameValidator added in v0.3.0 

func DeterministicDepositsAndKeysSameValidator(numDeposits uint64) ([]*ethpb.Deposit, []bls.SecretKey, error)

DeterministicDepositsAndKeysSameValidator returns the entered amount of deposits and secret keys of the same validator. This is for negative test cases such as same deposits from same validators in a block don't result in duplicated validator indices.

func DeterministicEth1Data added in v0.3.0 

func DeterministicEth1Data(size int) (*ethpb.Eth1Data, error)

DeterministicEth1Data takes an array of deposits and returns the eth1Data made from the deposit trie.

func DeterministicGenesisState added in v0.3.0 

func DeterministicGenesisState(t testing.TB, numValidators uint64) (iface.BeaconState, []bls.SecretKey)

DeterministicGenesisState returns a genesis state made using the deterministic deposits.

func FillRootsNaturalOpt added in v1.3.5 

func FillRootsNaturalOpt(state *pb.BeaconState) error

FillRootsNaturalOpt is meant to be used as an option when calling NewBeaconState. It fills state and block roots with hex representations of natural numbers starting with 0. Example: 16 becomes 0x00...0f.

func GenerateAttestations added in v0.3.0 

func GenerateAttestations(
	bState iface.BeaconState, privs []bls.SecretKey, numToGen uint64, slot types.Slot, randomRoot bool,
) ([]*ethpb.Attestation, error)

GenerateAttestations creates attestations that are entirely valid, for all the committees of the current state slot. This function expects attestations requested to be cleanly divisible by committees per slot. If there is 1 committee in the slot, and numToGen is set to 4, then it will return 4 attestations for the same data with their aggregation bits split uniformly.

If you request 4 attestations, but there are 8 committees, you will get 4 fully aggregated attestations.

func GenerateAttesterSlashingForValidator added in v0.3.2 

func GenerateAttesterSlashingForValidator(
	bState iface.BeaconState,
	priv bls.SecretKey,
	idx types.ValidatorIndex,

GenerateAttesterSlashingForValidator for a specific validator index.

func GenerateFullBlock 

func GenerateFullBlock(
	bState iface.BeaconState,
	privs []bls.SecretKey,
	conf *BlockGenConfig,
	slot types.Slot,
) (*ethpb.SignedBeaconBlock, error)

GenerateFullBlock generates a fully valid block with the requested parameters. Use BlockGenConfig to declare the conditions you would like the block generated under.

func GenerateProposerSlashingForValidator added in v0.3.2 

func GenerateProposerSlashingForValidator(
	bState iface.BeaconState,
	priv bls.SecretKey,
	idx types.ValidatorIndex,
) (*ethpb.ProposerSlashing, error)

GenerateProposerSlashingForValidator for a specific validator index.
