Functions ¶

func GetBlockByHash ¶

func GetBlockByHash(blockBucket *bbolt.Bucket, hash []byte) (*ngtypes.FullBlock, error)

func GetBlockByHeight ¶

func GetBlockByHeight(blockBucket *bbolt.Bucket, height uint64) (*ngtypes.FullBlock, error)

func GetLatestBlock ¶

func GetLatestBlock(blockBucket *bbolt.Bucket) (*ngtypes.FullBlock, error)

func GetLatestHash ¶

func GetLatestHash(blockBucket *bbolt.Bucket) ([]byte, error)

func GetLatestHeight ¶

func GetLatestHeight(blockBucket *bbolt.Bucket) (uint64, error)

func GetOriginBlock ¶

func GetOriginBlock(blockBucket *bbolt.Bucket) (*ngtypes.FullBlock, error)

func GetOriginHash ¶

func GetOriginHash(blockBucket *bbolt.Bucket) ([]byte, error)

func GetOriginHeight ¶

func GetOriginHeight(blockBucket *bbolt.Bucket) (uint64, error)

func GetTxByHash ¶

func GetTxByHash(txBucket *bbolt.Bucket, hash []byte) (*ngtypes.FullTx, error)

func PutNewBlock ¶

func PutNewBlock(blockBucket *bbolt.Bucket, txBucket *bbolt.Bucket, block *ngtypes.FullBlock) error

PutNewBlock puts a new block into db and updates the tags. should check block before putting dev should continue upgrading the state after PutNewBlock

Types ¶

type BlockStore ¶

type BlockStore struct {
	*bbolt.DB
	Network ngtypes.Network
}

BlockStore managers a badger DB, which stores vaults and blocks and some helper tags for managing. TODO: Add DAG support to extend the capacity of store initialize with genesis blocks first, then load the origin in bootstrap process

func Init ¶

func Init(db *bbolt.DB, network ngtypes.Network) *BlockStore

Init will do all initialization for the block store.

func (*BlockStore) ForcePutNewBlock ¶

func (store *BlockStore) ForcePutNewBlock(blockBucket *bbolt.Bucket, txBucket *bbolt.Bucket, block *ngtypes.FullBlock) error

ForcePutNewBlock puts a block into db regardless of local store check should check block self before putting

func (*BlockStore) InitFromCheckpoint ¶

func (store *BlockStore) InitFromCheckpoint(block *ngtypes.FullBlock) error
