+## 1.0.0
+- significantly redesigned interface
+- based on [Waves Crypto](https://github.com/wavesplatform/waves-crypto-java) and [Waves transactions](https://github.com/wavesplatform/waves-transactions-java) libraries
+- supported most of Waves Node API
+- feature #15 of Waves Node 1.2 Malibu release is now supported
+
 ## 0.17.0
 - new InvokeScriptTransactionStCh with stateChanges attribute was added. It was design to provide an additional information about Invocation transaction and couldn't be used to post invokes into blockchain. That why constructor was marked as package-private
 - new AllTxIterator class to navigate over all account transactions. It has a generic semantic and can be used for other endpoints and transaction.

 ## Basic Usage
 Create an account from a private key ('T' for testnet):
 ```java
-String seed = "health lazy lens fix dwarf salad breeze myself silly december endless rent faculty report beyond";
-PrivateKeyAccount account = PrivateKeyAccount.fromSeed(seed, 0, Account.TESTNET);
-byte[] publicKey = account.getPublicKey();
-String address = account.getAddress();
+String seed = Crypto.getRandomSeedPhrase();
+PrivateKey privateKey = PrivateKey.fromSeed(seed);
+PublicKey publicKey = PublicKey.from(privateKey);
+Address address = Address.from(publicKey);
 ```
 
 Create a Node and learn a few things about blockchain:
 ```java
-Node node = new Node("https://testnode2.wavesnodes.com/", Account.TESTNET);
+Node node = new Node(Profile.MAINNET);
 System.out.println("Current height is " + node.getHeight());
 System.out.println("My balance is " + node.getBalance(address));
 System.out.println("With 100 confirmations: " + node.getBalance(address, 100));
 ```
 
 Send some money to a buddy:
 ```java
-String buddy = "3N9gDFq8tKFhBDBTQxR3zqvtpXjw5wW3syA";
-String txId = node.transfer(account, buddy, 1_00000000, 100_000, "Here's for you");
+Address buddy = new Address("3N9gDFq8tKFhBDBTQxR3zqvtpXjw5wW3syA");
+node.broadcast(TransferTransaction.builder(buddy, Amount.of(1_00000000, Asset.WAVES)).getSignedWith(privateKey));
 ```
 
 Set a script on an account. Be careful with the script you pass here, as it may lock the account forever!
 ```java
-String setScriptTxId = node.setScript(alice, "tx.type == 13 && height > " + height, Account.TESTNET, SCRIPT_FEE);
+Base64String script = node
+    .compile("{-# CONTENT_TYPE EXPRESSION #-} sigVerify(tx.bodyBytes, tx.proofs[0], tx.senderPublicKey)")
+    .script();
+node.broadcast(new SetScriptTransaction(publicKey, script).addProof(privateKey));
 ```
-
-Sign a transaction offline:
-```java
-Transaction tx = Transaction.makeTransferTx(account, buddy, 1_00000000, Asset.WAVES, 100_000, Asset.WAVES, "");
-System.out.println("JSON encoded data: " + tx.getJson());
-System.out.println("Server endpoint to send this JSON to: " + tx.getEndpoint());
-```
-
-Now send it from an online machine:
-```java
-node.send(tx);
-```
-
-Create a DEX order:
-```java
-Node matcher = new Node("https://testnode2.wavesnodes.com", Account.TESTNET);
-String matcherKey = matcher.getMatcherKey();
-String wbtcId = "Fmg13HEHJHuZYbtJq8Da8wifJENq8uBxDuWoP9pVe2Qe";
-Order order = matcher.createOrder(alice, matcherKey,
-                new AssetPair(Asset.WAVES, wbtcId),
-                // buy 10 WAVES at 0.00090000 WBTC each
-                Order.Type.BUY, 90_000, 10 * Asset.TOKEN,
-                // make order valid for 1 hour
-                System.currentTimeMillis() + 3_600_000, MATCHER_FEE);
-System.out.printf("Filed order " + order.id);
-```

-```
-mvn clean package -DbenzPrivateKey=YourPrivateKeyOnTestnetWith10Waves
