+# asmt
+
+asmt is a GoLang sparse merkle tree. 
+
+A forked of [Aergo SMT](https://github.com/aergoio/aergo/tree/develop/pkg/trie) with minor style code modifications 
+and some new methods: Walk() WalkWithRoot() and GetWithRoot().
+
+This module includes an abstraction layer to make the SMT more developer friendly with a very easy to use API:
+
++ Init(name, dataDir string) error
++ LastAccess() (timestamp int64)
++ Add(key, value []byte) error
++ AddBatch(keys, values [][]byte) (failedIndexes []int, err error)
++ GenProof(key, value []byte) (mproof []byte, err error)
++ CheckProof(key, value, root, mproof []byte) (included bool, err error)
++ Root() []byte
++ HashExists(hash []byte) (bool, error)
++ Dump(root []byte) (data []byte, err error) // Dump must return a format compatible with ImportDump
++ DumpPlain(root []byte) (keys [][]byte, values [][]byte, err error)
++ ImportDump(data []byte) error
++ Size(root []byte) (int64, error)
++ Snapshot(root []byte) (Tree, error) // Snapshot is a frozen trie on a specific Root hash that cannot be modified
+
