-See [https://github.com/bigchaindb/bigchaindb/blob/master/CODE_OF_CONDUCT.md](https://github.com/bigchaindb/bigchaindb/blob/master/CODE_OF_CONDUCT.md)
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, sexual identity and orientation, or species—no picking on Wrigley for being a buffalo!
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at conduct@bigchaindb.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

-# Our Release Process
-
-## Notes
-
-BigchainDB follows
-[the Python form of Semantic Versioning](https://packaging.python.org/tutorials/distributing-packages/#choosing-a-versioning-scheme)
-(i.e. MAJOR.MINOR.PATCH),
-which is almost identical
-to [regular semantic versioning](http://semver.org/), but there's no hyphen, e.g.
-
-- `0.9.0` for a typical final release
-- `4.5.2a1` not `4.5.2-a1` for the first Alpha release
-- `3.4.5rc2` not `3.4.5-rc2` for Release Candidate 2
-
-**Note:** For Git tags (which are used to identify releases on GitHub), we append a `v` in front.
-
-We follow [BEP-1](https://github.com/bigchaindb/BEPs/tree/master/1), which is our variant of C4, the Collective Code Construction Contract, so a release is just a [tagged commit](https://git-scm.com/book/en/v2/Git-Basics-Tagging) on the `master` branch, i.e. a label for a particular Git commit.
-
-## Steps
-
-1. Make sure you have a recent version of node and npm.
-1. `npm install`
-1. Update all npm package dependencies, where possible. You might have to freeze some versions. Run all tests locally (`npm run test`) and make sure they pass. Make a pull request (to be merged into the `master` branch) and make sure all tests are passing there (in Travis). Merge the pull request.
-1. Make sure your local `master` branch is in sync with GitHub: `git checkout master` and `git pull`
-1. Do a test build:
-
-   `npm run build`
-
-   If that fails, then get it working.
-1. We use the [release-it](https://www.npmjs.com/package/release-it) package (from npm) to automate most of the release. Make sure you have a recent version.
-1. Login to npm using your npm credentials, so you can publish a new [bigchaindb-driver](https://www.npmjs.com/package/bigchaindb-driver) package there. (The npm account must have permission to do so).
-
-   `npm login`
-
-1. release-it needs a Github personal access token so it can interact with GitHub on your behalf. To get one, go to:
-
-   [https://github.com/settings/tokens](https://github.com/settings/tokens)
-
-   and then make that token available as an environment variable, e.g.
-
-   `export GITHUB_TOKEN="f941e0..."`
-
-1. Do the release:
-
-   - For a patch release, do `npm run release`
-   - For a minor release, do `npm run release-minor`
-   - For a major release, do `npm run release-major`
-
-   If your npm account is using two-factor authentication,
-   you will have to append a one-time password (OTP) like `--npm.otp=123456`.
-   The above command will automatically do a bunch of things:
-
-   - bump the project version in `package.json`, then git commit and git push it.
-   - create a new Git tag of the form `v{verson}`, e.g. `v1.2.3`
-   - create a new [GitHub release](https://github.com/bigchaindb/js-bigchaindb-driver/releases).
-   - publish a new npm release
-
-   To see all the arguments passed to `release-it`, search for "release" in [package.json](package.json). The arguments are documented in the [release-it GitHub repo](https://github.com/release-it/release-it).
-
-1. Make sure everything worked as expected.
-
-   - Was the version number bumped properly in [package.json](package.json)?
-   - Was a new Git tag created? See the [list of tags](https://github.com/bigchaindb/js-bigchaindb-driver/tags).
-   - Was a new GitHub release created? See the [list of releases](https://github.com/bigchaindb/js-bigchaindb-driver/releases).
-   - Was a new npm package published on npm? [Check on npmjs.com](https://www.npmjs.com/package/bigchaindb-driver).
-
-1. You can edit the description of the GitHub release to add or remove details.
-
-If the docs were updated since the last release, [login to readthedocs.org](https://readthedocs.org/accounts/login/) and go to the **BigchainDB JavaScript Driver** project, then:
-
-1. Click on "Builds", select "latest" from the drop-down menu, then click the "Build Version:" button.
-1. Wait for the build of "latest" to finish. This can take a few minutes.
-1. Go to Admin --> Advanced Settings
-   and make sure that "Default branch:" (i.e. what "latest" points to)

-   (It won't be an option if you didn't wait for the build of "latest" to finish.)
-   Then scroll to the bottom and click "Save".
-1. Go to Admin --> Versions
-   and under **Choose Active Versions**, do these things:
-
-   1. Make sure that the new version's tag is "Active" and "Public"
-   1. Make sure the **stable** branch is _not_ active.
-   1. Scroll to the bottom of the page and click "Save".
-
-Congratulations, you have released a new version of the BigchainDB JavaScript Driver!

-Advanced Examples
-=================
-
-Crypto Conditions
------------------
-
-Let's start with a basic use case example. Alice bought a bicycle for €240.
-She will use the bike for a year and will give it to her daughter afterwards.
-First, we create an asset registering the bicycle:
-
-.. code-block:: js
-
-    const txCreateAliceSimple = driver.Transaction.makeCreateTransaction(
-        {'asset': 'bicycle'},
-        {'purchase_price': '€240'},
-        [
-            driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(alice.publicKey))
-        ],
-        alice.publicKey
-    )
-
-    const txCreateAliceSimpleSigned = driver.Transaction.signTransaction(txCreateAliceSimple, alice.privateKey)
-
-After a year, she decides it's time to transfer the bicycle to her daughter Carly.
-However, Alice wants to maintain the right over the bike so she can possibly sell it. If she would transfer the bicycle to Carly, she won't be able to do this.
-So, Alice needs a crypto conditions that defines that she or her daughter can sign the ``TRANSFER`` transaction to a possible buyer.
-
-We need to define a threshold as well. This defines how many persons have to sign the transaction to ``TRANSFER`` it.
-In this case, we define two subconditions with the public keys from Alice and Carly. Next, we set the threshold to **one**.
-This means that just one of the subconditions has to sign the transaction to transfer it.
-This can be the mother Alice, or Carly herself.
-
-.. code-block:: js
-
-    // Create condition for Alice and Carly
-    let subConditionFrom = driver.Transaction.makeEd25519Condition(alice.publicKey, false)
-    let subConditionTo = driver.Transaction.makeEd25519Condition(carly.publicKey, false)
-
-    // Create condition object with threshold and subconditions
-    let condition = driver.Transaction.makeThresholdCondition(1, [subConditionFrom, subConditionTo])
-
-    // Generate output with condition added
-    let output = driver.Transaction.makeOutput(condition)
-
-    // Add Carly to the output.public_keys field so she is the owner
-    output.public_keys = [carly.publicKey]
-
-    let transaction = driver.Transaction.makeTransferTransaction(
-  		[{ tx: txCreateAliceSimpleSigned, output_index: 0 }],
-      [output],
-  		{'meta': 'Transfer to new user with conditions'}
-  	);
-
-    // Add alice as previous owner
-    transaction.inputs[0].owners_before = [alice.publicKey]
-
-    // Because the addition of crypto conditions, the id for the transaction has to be regenerated
-    delete transaction.id
-    transaction.id = sha3.sha3_256
-        .create()
-        .update(driver.Transaction.serializeTransactionIntoCanonicalString(transaction))
-        .hex()
-
-    // Alice has to sign this transfer because she is still the owner of the created asset
-    let signedCryptoConditionTx = driver.Transaction.signTransaction(transaction, alice.privateKey)
-
-As you can see, we need to generate a new transactionId because we have added crypto conditions.
-We do this with the js-sha3 package, you need to install this package through ``npm``:
-
-``npm install --save js-sha3``
-
-Don't forget to import the package in your code:
-
-.. code-block:: js
-
-    import * as sha3 from 'js-sha3'
-
-
-If you would like to see a more complex example, please have a look [here](https://github.com/bigchaindb/project-jannowitz/blob/code-examples/js-examples/crypto-conditions.js)

-
-Older versions
---------------------
-
-**Version 4.x.x**
-
-	As part of the changes in the BigchainDB 2.0 server, some endpoints were
-	modified. In order to be consistent with them, the JS driver does not have
-	anymore the `pollStatusAndFetchTransaction()` method as there are three
-	different ways of posting a transaction:
-
-	- `commit` using the `postTransaction` or the `postTransactionCommit`: the response will return after the transaction is committed to a block.
-	- `sync` using the `postTransactionSync`: the response will return after the transaction is validated.
-	- `async` using the `postTransactionAsync`: the response will return immediately and not wait to see if the transaction is valid.
-
-	By default in the docs we will use the `postTransactionCommit` as is way of
-	being sure that the transaction is validated and commited to a block, so
-	there will not be any issue if you try to do any other action with the asset immediately.
-
-	Note: In order to not create breaking changes, both methods `postTransaction` and `postTransactionCommit` are kept although
-	they do exactly the same
-
-
-**Version 3.2.x**
-
-	For versions below 3.2, a transfer transaction looked like:
-
-	.. code-block:: js
-
-		const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
-		    txCreated,
-		    metadata, [BigchainDB.Transaction.makeOutput(
-		        BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
-		    0
-		)
-
-		const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
-			keypair.privateKey)
-
-
-	In order to upgrade and do it compatible with the new driver version, this
-	transaction should be now:
-
-	.. code-block:: js
-
-		const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
-			[{ tx: txCreated, output_index: 0 }],
-			[BigchainDB.Transaction.makeOutput(
-	        BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
-			metaData
-		)
-
-		const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
-			keypair.privateKey)
-
-
-	The upgrade allows to create transfer transaction spending outputs that belong
-	to different transactions. So for instance is now possible to create a transfer
-	transaction spending two outputs from two different create transactions:
-
-
-	.. code-block:: js
-
-		const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
-			[{ tx: txCreated1, output_index: 0 },
-				{ tx: txCreated2, output_index: 0}],
-			[BigchainDB.Transaction.makeOutput(
-	        BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
-			metaData
-		)
-
-		const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
-			keypair.privateKey)

-====================
-Basic Usage Examples
-====================
-
-For the examples on this page, we assume you've
-:doc:`installed the bigchaindb_driver JavaScript package <quickstart>`,
-and you have determined the BigchainDB Root URL (issue: move this to general docs)
-of the node or cluster you want to connect to.
-
-This example guides you through creating and transferring an asset.
-We walk through the code explaining its use, some pieces are left out
-because they have no real use (e.g. definition of global variable)
-*Full working code* can be found at the bottom of this document.
-The following code are just snippets.
-
-Getting Started
----------------
-We begin by importing the BigchainDB driver:
-
-.. code-block:: js
-
-	const driver = require('bigchaindb-driver')
-
-Next, we define a constant containing the API path.
-
-.. code-block:: js
-
-	const API_PATH = 'http://localhost:9984/api/v1/'
-
-Create a Connection with BigchainDB
------------------------------------
-
-A simple connection with a BigchainDB node can be established like this:
-
-.. code-block:: js
-
-	const conn = new driver.Connection(API_PATH)
-
-If the BigchainDB node requires special HTTP request headers
-(such as ``app_id`` and ``app_key``),
-they can be included like this:
-
-.. code-block:: js
-
-	const conn = new driver.Connection(API_PATH, {
-		app_id: 'app_id_value',
-		app_key: 'app_key_value'
-	})
-
-A more complex connection can be created if the BigchainDB network
-has several nodes, each with a different API path and different required headers.
-The connection strategy will be the one specified in BEP-14_.
-
-.. _BEP-14: https://github.com/bigchaindb/BEPs/tree/master/14#connection-strategy
-
-.. code-block:: js
-
-	const conn = new driver.Connection([
-    API_PATH_1,  // the first node does not use custom headers, only common headers

-
-Cryptographic Identities Generation
------------------------------------
-
-Alice and Bob are represented by public/private key pairs. The private key is
-used to sign transactions, meanwhile the public key is used to verify that a
-signed transaction was indeed signed by the one who claims to be the signee.
-
-.. code-block:: js
-
-	const alice = new driver.Ed25519Keypair()
-	const bob = new driver.Ed25519Keypair()
-
-Digital Asset Definition
-------------------------
-
-As an example, let’s consider the creation and transfer of a digital asset
-that represents a bicycle:
-
-.. code-block:: js
-
-	const assetdata = {
-		'bicycle': {
-			'serial_number': 'abcd1234',
-			'manufacturer': 'Bicycle Inc.',
-		}
-	}
-
-We'll suppose that the bike belongs to Alice, and that it eventually will be
-transferred to Bob.
-
-In general, you are free to define any JSON object you which to store for the
-``'data'`` property (assetdata).
-
-Metadata Definition (*optional*)
---------------------------------
-
-You can `optionally` add metadata to a transaction. Any JSON object is accepted.
-
-For example, the bicycle will be transferred on earth which is metadata:
-
-.. code-block:: js
-
-	const metadata = {'planet': 'earth'}
-
-Asset Creation
---------------
-
-We're now ready to create the digital asset. First, let's make a 'CREATE'
-transaction:
-
-.. code-block:: js
-
-	const txCreateAliceSimple = driver.Transaction.makeCreateTransaction(
-   		assetdata,
-   		metadata,
-
-		// A transaction needs an output
-		[ driver.Transaction.makeOutput(
-			driver.Transaction.makeEd25519Condition(alice.publicKey))
-		],
-		alice.publicKey
-	)
-
-Transaction needs an array of Output objects.
-Think of these as the recipients of the asset after the transaction.
-For `CREATE` Transactions, this should usually just be a list of
-Outputs wrapping Ed25519 Conditions generated from the issuers' public
-keys (so that the issuers are the recipients of the created asset).
-
-``alice.publicKey`` can be considered as the Input for the transaction.
-Each input spends/transfers a previous output by satisfying/fulfilling
-the crypto-conditions on that output. A CREATE transaction should have
-exactly one input. A TRANSFER transaction should have at least one input (i.e. ≥1).
-
-Sign the transaction with private key of Alice to fulfill it:
-
-.. code-block:: js
-
-	driver.Transaction.signTransaction(txCreateAliceSimple, alice.privateKey)
-
-And sent over to a BigchainDB node:
-
-.. code-block:: js
-
-	conn.postTransactionCommit(txCreateAliceSimpleSigned)
-
-Notice the transaction ``id``:
-
-.. code-block:: js
-
-	txid = txCreateAliceSimpleSigned.id
-
-Asset Transfer
---------------
-
-Imagine some time goes by, during which Alice is happy with her bicycle, and
-one day, she meets Bob, who is interested in acquiring her bicycle. The timing
-is good for Alice as she had been wanting to get a new bicycle.
-
-To transfer the bicycle (asset) to Bob, Alice must consume the transaction's output in
-which the Bicycle asset was created.
-
-Alice could retrieve the transaction:
-
-.. code-block:: js
-
-	conn.getTransaction(txCreateAliceSimpleSigned.id)
-
-First, let's prepare the transaction to be transferred.
-
-.. code-block:: js
-
-	const txTransferBob = driver.Transaction.makeTransferTransaction(
-		// signedTx to transfer and output index
-		[{ tx: txCreateAliceSimpleSigned, output_index: 0 }],
-
-		[driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(bob.publicKey))],
-
-		// metadata
-		{price: '100 euro'}
-	);
-
-The function ``makeTransferTransaction()`` needs following parameters:
-
-- Unspent outputs: Array of `unspent transactions outputs`. Each item contains `Transaction` itself and index of `unspent output` for that `Transaction`.
-- Array of output objects to add to the transaction: Think of these as the recipients of the asset after the transaction. For `TRANSFER` transactions, this should usually just be a list of outputs wrapping Ed25519 conditions generated from the public keys of the recipients.
-- Metadata for transaction (e.g. price of sold bike)
-
-Fulfill transaction by signing it with Alice's private key.
-
-.. code-block:: js
-
-	driver.Transaction.signTransaction(txTransferBob, alice.privateKey);
-
-And sent over to a BigchainDB node:
-
-.. code-block:: js
-
-	conn.postTransactionCommit(txTransferBobSigned)
-
-Check the status again:
-
-
-Bob is the new owner:
-
-.. code-block:: js
-
-	console.log('Is Bob the owner?', txTransferBobSigned['outputs'][0]['public_keys'][0] == bob.publicKey)
-	// Output: true
-
-Alice is the former owner:
-
-.. code-block:: js
-
-	console.log('Was Alice the previous owner?', txTransferBobSigned['inputs'][0]['owners_before'][0] == alice.publicKey )
-	// Output: true
-
-
-Querying for Assets
--------------------
-
-BigchainDB allows you to query for assets using simple text search. This search is applied to all the strings inside the asset payload and returns all the assets that match a given text search string.
-
-BigchainDB also allows you to query for metadata, but there are some differences. The response of the text search call, beside retrieving the asset or metadata in each case, it consist of:
- - In the assets search the call returns the asset id which is the same id of the transaction that created the asset.
- - In the metadata search the call returns the transaction id that contains this metadata.
-
-Let’s assume that we created 3 assets that look like this:
-
-.. code-block:: js
-
-	assets = [
-	   {'data': {'bicycle': {'serial_number': 'abc', manufacturer: 'Bicycle Inc.'}}},
-	   {'data': {'bicycle': {'serial_number': 'cde', manufacturer: 'Bicycle Inc.'}}},
-	   {'data': {'bicycle': {'serial_number': 'fgh', manufacturer: 'Bicycle Inc.'}}}
-	]
-
-Let’s perform a text search for all assets that contain the word 'Bicycle Inc.':
-
-.. code-block:: js
-
-	conn.searchAssets('Bicycle Inc.')
-    		.then(assets => console.log('Found assets with serial number Bicycle Inc.:', assets))
-
-Which leads to following result:
-
-.. code-block:: js
-
-	[
-	   {
-		'data': {'bicycle': {'serial_number': 'abc', manufacturer: 'Bicycle Inc.'}},
-		'id': '7582d7a81652d0230fefb47dafc360ff09b2c2566b68f05c3a004d57e7fe7610'
-	   },
-	   {
-		'data': {'bicycle': {'serial_number': 'cde', manufacturer: 'Bicycle Inc.'}},
-		'id': 'e40f4b6ac70b9c1b3b237ec13f4174384fd4d54d36dfde25520171577c49caa4'
-	   },
-	   {
-		'data': {'bicycle': {'serial_number': 'fgh', manufacturer: 'Bicycle Inc.'}},
-		'id': '748f6c30daaf771c9020d84db9ad8ac4d1f7c8de7013db55e16f10ba090f7013'
-	   }
-	]
-
-
-This call returns all the assets that match the string 'Bicycle Inc.', sorted by text score, as well as the asset id.
-
-
-Querying for Metadata
----------------------
-
-Similar as querying for assets, in BigchainDB you can query for metadata using simple text search.
-This search is applied to all the strings inside the metadata payload and returns all the metadata payloads that match a given text search string.
-
-Having 3 metadata objets that look like this:
-
-.. code-block:: js
-
-	metadata = [
-	   {'state': {'price': 145, 'eur/us': '1.32'}},
-	   {'state': {'price': 236, 'eur/us': '1.15'}},
-	   {'state': {'price': 102, 'eur/us': '1.32'}},
-	]
-
-Let’s perform a text search for all metadata that contains the word '1.32':
-
-.. code-block:: js
-
-	conn.searchMetadata('1.32')
-    		.then(assets => console.log('Found assets with serial number Bicycle Inc.:', assets))
-
-Which leads to following result:
-
-.. code-block:: js
-
-	[
-	   {
-		'metadata': {'state': {'price': 145, 'eur/us': '1.32'}},
-		'id': '14045a0e27ea971f8ac88762d2d74518d3a21f3f0fcd9d8a9a3b644b689cf3eb'
-	   },
-	   {
-		'metadata': {'state': {'price': 102, 'eur/us': '1.32'}},
-		'id': '6dd91f4700b3f66c55c50be009018e96f026d37f565d042d1aedfb322623d17d'
-	   }
-	]
-
-
-This call returns all the metadata objects that match the string '1.32', sorted by text score, as well as the transaction id corresponding to each metadata object.
-
-
-
-Recap: Asset Creation & Transfer
---------------------------------
-
-.. code-block:: js
-
-	const driver = require('bigchaindb-driver')
-
-	// BigchainDB server instance or testnetwork (e.g. https://example.com/api/v1/)
-	const API_PATH = 'http://localhost:9984/api/v1/'
-
-	// Create a new keypair for Alice and Bob
-	const alice = new driver.Ed25519Keypair()
-	const bob = new driver.Ed25519Keypair()
-
-	console.log('Alice: ', alice.publicKey)
-	console.log('Bob: ', bob.publicKey)
-
-	// Define the asset to store, in this example
-	// we store a bicycle with its serial number and manufacturer
-	const assetdata = {
-		'bicycle': {
-			'serial_number': 'cde',
-			'manufacturer': 'Bicycle Inc.',
-		}
-	}
-
-	// Metadata contains information about the transaction itself
-	// (can be `null` if not needed)
-	// E.g. the bicycle is fabricated on earth
-	const metadata = {'planet': 'earth'}
-
-	// Construct a transaction payload
-	const txCreateAliceSimple = driver.Transaction.makeCreateTransaction(
-		assetdata,
-		metadata,
-
-		// A transaction needs an output
-		[ driver.Transaction.makeOutput(
-				driver.Transaction.makeEd25519Condition(alice.publicKey))
-		],
-		alice.publicKey
-	)
-
-	// Sign the transaction with private keys of Alice to fulfill it
-	const txCreateAliceSimpleSigned = driver.Transaction.signTransaction(txCreateAliceSimple, alice.privateKey)
-
-	// Send the transaction off to BigchainDB
-	const conn = new driver.Connection(API_PATH)
-
-	conn.postTransactionCommit(txCreateAliceSimpleSigned)
-		.then(retrievedTx => console.log('Transaction', retrievedTx.id, 'successfully posted.'))
-		// With the postTransactionCommit if the response is correct, then the transaction
-		// is valid and commited to a block
-
-		// Transfer bicycle to Bob
-		.then(() => {
-			const txTransferBob = driver.Transaction.makeTransferTransaction(
-				// signedTx to transfer and output index
-				[{ tx: txCreateAliceSimpleSigned, output_index: 0 }],
-				[driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(bob.publicKey))],
-				// metadata
-				{price: '100 euro'}
-			)
-
-			// Sign with alice's private key
-			let txTransferBobSigned = driver.Transaction.signTransaction(txTransferBob, alice.privateKey)
-			console.log('Posting signed transaction: ', txTransferBobSigned)
-
-			// Post with commit so transaction is validated and included in a block
-			return conn.postTransactionCommit(txTransferBobSigned)
-		})
-		.then(tx => {
-			console.log('Response from BDB server:', tx)
-			console.log('Is Bob the owner?', tx['outputs'][0]['public_keys'][0] == bob.publicKey)
-			console.log('Was Alice the previous owner?', tx['inputs'][0]['owners_before'][0] == alice.publicKey )
-		})
-		// Search for asset based on the serial number of the bicycle
-		.then(() => conn.searchAssets('Bicycle Inc.'))
-		.then(assets => console.log('Found assets with serial number Bicycle Inc.:', assets))
-
-
-Ed25519Keypair Seed Functionality
----------------------------------
-
-BigchainDB JavaScript driver allows you to create a keypair based on a seed.
-The constructor accepts a 32 byte seed. One of the ways to create a seed from
-a string (e.g. a passphrase) is the one used by ``bip39``, specifically the function ``mnemonicToSeed``.
-
-Install bip39 with npm: ``npm install bip39``
-
-Next, require ``bip39`` in your file like this: ``var bip39 = require('bip39')``
-
-At last, we can create the keypair based on a string. The function will transform the string to a byte array.
-As our constructor ``Ed25519Keypair()`` only accepts a seed of 32 bytes, we slice the first 32 bytes: ``slice(0,32)``.
-
-.. code-block:: js
-
-	var keypair = new driver.Ed25519Keypair(bip39.mnemonicToSeed("yourString").slice(0, 32))
-
-You can use the ``Ed25519Keypair()`` constructor as well without seed.
-
-.. code-block:: js
-
-	var keypair = new driver.Ed25519Keypair()
-
-
-
-Websocket Event Stream API Usage
---------------------------------
-
-The Event Stream API enables new ways to interact with BigchainDB,
-making it possible for your application to subscribe
-to all newly–confirmed transactions that are happening in the system.
-Below piece of code can be opened in your web browser.
-It will connect to your websocket (if you are using the testnet, redefine
-``var wsUri ='wss://insert-testnet-subdomain-here.com:443/api/v1/streams/valid_transactions'``).
-This web page will display all validated transactions.
-

-		console.log("\nTransactionId: ", json.transaction_id)
-		console.log("AssetId: ", json.asset_id)
-		console.log("BlockId: ", json.block_id)
-	});
-
-
-Difference unspent and spent output
------------------------------------
-An unspent output is simply an output of a transaction which isn't yet an input of another transaction.
-So, if we transfer an asset, the output becomes spent, because it becomes the input of the transfer transaction.
-The transfer transactions its output becomes unspent now until he transfers the asset again to somebody else.
-
-We will demonstrate this with a piece of code where we transfer a bicycle from Alice to Bob,
-and further we transfer it from Bob to Chris. Expectations:
-
-* Output for Alice is spent
-* Output for Bob is spent
-* Output for Chris is unspent (he is the last person in transaction chain)
-
-.. code-block:: js
-
-	const driver = require('bigchaindb-driver')
-	const API_PATH = 'http://localhost:9984/api/v1/'
-	const conn = new driver.Connection(API_PATH)

-			return conn.listOutputs(bob.publicKey, true)
-		})
-		.then(listSpentOutputs => {
-			console.log("\nSpent outputs for Bob: ", listSpentOutputs.length) // Spent outputs: 1
-			return conn.listOutputs(bob.publicKey, false)
-		})
-		.then(listUnspentOutputs => {

-			return conn.listOutputs(chris.publicKey, false)
-		})
-		.then(listUnspentOutputs => {
-			console.log("Unspent outputs for Chris: ", listUnspentOutputs.length) // Unspent outputs: 1
-		})
-		.catch(res => {console.log(res)})
-
-Output of above code looks like this. As you can see, Chris has no spent output, but one unspent output.
-
-.. code-block:: js
-
-	Spent outputs for Alice:  1
-	Unspent outputs for Alice:  0
-
-	Spent outputs for Bob:  1
-	Unspent outputs for Bob:  0
-
-	Spent outputs for Chris:  0
-	Unspent outputs for Chris:  1
-
-Divisible Assets
-----------------
-
-All assets in BigchainDB become implicitly divisible if a transaction contains more than one of that asset (we’ll see how this happens shortly).
-
-Let's assume we have created a token to pay each other for small transactions like a beer or some food between friends.
-
-.. code-block:: js
-
-	const token = {
-		'value': '1 euro'
-	}
-
-Let's create the asset. Note that we give an extra parameter to the ``makeOutput()`` function.
-We give it the parameter ``'4'`` to indicate that we want to create 4 tokens.
-**Pay attention to give the function a String instead of a plain Number.**
-
-.. code-block:: js
-
-	const txCreateAliceDivisible = driver.Transaction.makeCreateTransaction(
-		token,
-		{metaDataMessage: 'I am specific to this create transaction'},
-		[driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(alice.publicKey), '4')],
-		alice.publicKey
-	)
-
-Alice goes dining at Bob and Carly. She decides to give a small fee to Bob and Carly.
-Alice decides to issue 4 tokens as a payment for her food: one to Bob, two to Carly and one to herself.
-Why one to herself? If you decide to fulfill an output, you have to spend all tokens.
-So if you want to keep one token for yourself, you have to transfer it to yourself.
-As you can see, we fulfill the first output of the create transaction (it's 0 because we start counting from 0).
-This gives us 4 tokens to transfer.
-
-.. code-block:: js
-
-	const txTransferDivisible = driver.Transaction.makeTransferTransaction(
-		[{ tx: txCreateAliceDivisibleSigned, output_index: 0 }],
-		[
-			driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(carly.publicKey), '2'),
-			driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(bob.publicKey), '1'),
-			driver.Transaction.makeOutput(driver.Transaction.makeEd25519Condition(alice.publicKey), '1')
-		],
-		{
-			metaDataMessage: 'I am specific to this transfer transaction'
-		}
-	);
-
-To make the use of the last parameter of ``makeTransferTransaction()`` function more clear, we will do another transfer.
-We will fulfill the first and second output of the create transaction (0, 1) because Carly and Bob decide to redistribute some money.
-
