# KVStore
The KVStoreApplication is a simple merkle key-value store.
Transactions of the form `key=value` are stored as key-value pairs in the tree.
Transactions without an `=` sign set the value to the key.
The app has no replay protection (other than what the mempool provides).
Validator set changes are effected using the following transaction format:
```md
"val:pubkey1!power1,pubkey2!power2,pubkey3!power3"
```
where `pubkeyN` is a base64-encoded 32-byte ed25519 key and `powerN` is a new voting power for the validator with `pubkeyN` (possibly a new one).
To remove a validator from the validator set, set power to `0`.
There is no sybil protection against new validators joining.
