Party
-----
Identities on the network are represented by ``AbstractParty``. There are two types of ``AbstractParty``:
Parties on the network are represented using the ``AbstractParty`` class. There are two types of ``AbstractParty``:
* ``Party``, identified by a ``PublicKey`` and a ``CordaX500Name``
* ``AnonymousParty``, identified by a ``PublicKey`` only
* ``AnonymousParty``, identified by a ``PublicKey``
Using ``AnonymousParty`` to identify parties in states and commands prevents nodes from learning the identities
of the parties involved in a transaction when they verify the transaction's dependency chain. When preserving the
anonymity of each party is not required (e.g. for internal processing), ``Party`` can be used instead.
For example, in a transaction sent to your node as part of a chain of custody it is important you can convince yourself
of the transaction's validity, but equally important that you don't learn anything about who was involved in that
transaction. In these cases ``AnonymousParty`` should be used by flows constructing when transaction states and commands.
In contrast, for internal processing where extended details of a party are required, the ``Party`` class should be used
instead. The identity service provides functionality for flows to resolve anonymous parties to full parties, dependent
on the anonymous party's identity having been registered with the node earlier (typically this is handled by
``SwapIdentitiesFlow`` or ``IdentitySyncFlow``, discussed below).
The identity service allows flows to resolve ``AnonymousParty`` to ``Party``, but only if the anonymous party's
identity has already been registered with the node (typically handled by ``SwapIdentitiesFlow`` or
``IdentitySyncFlow``, discussed below).
Party names are held within the ``CordaX500Name`` data class, which enforces the structure of names within Corda, as
well as ensuring a consistent rendering of the names in plain text.
Party names use the ``CordaX500Name`` data class, which enforces the structure of names within Corda, as well as
ensuring a consistent rendering of the names in plain text.
The support for both Party and AnonymousParty classes in Corda enables sophisticated selective disclosure of identity
information. For example, it is possible to construct a Transaction using an AnonymousParty, so nobody can learn of your
involvement by inspection of the transaction, yet prove to specific counterparts that this AnonymousParty actually is
owned by your well known identity. This disclosure is achieved through the use of the PartyAndCertificate data class
which can be propagated to those who need to know, and contains the Party's X.509 certificate path to provide proof of
ownership by a well known identity.

``AnonymousParty`` actually corresponds to your well-known identity. This is achieved using the
``PartyAndCertificate`` data class, which contains the X.509 certificate path proving that a given ``AnonymousParty``
corresponds to a given ``Party``. Each ``PartyAndCertificate`` can be propagated to counterparties on a need-to-know
basis.
The PartyAndCertificate class is also used in the network map service to represent well known identities, in which
scenario the certificate path proves its issuance by the Doorman service.

Confidential Identities
Confidential identities
-----------------------
Confidential identities are key pairs where the corresponding X.509 certificate (and path) are not made public, so that parties who
are not involved in the transaction cannot identify its participants. They are owned by a well known identity, which
must sign the X.509 certificate. Before constructing a new transaction the involved parties must generate and send new
confidential identities to each other, a process which is managed using ``SwapIdentitiesFlow`` (discussed below). The
public keys of these confidential identities are then used when generating output states and commands for the transaction.

exchange new confidential identities, a process which is managed using ``SwapIdentitiesFlow`` (discussed below). The
public keys of these confidential identities are then used when generating output states and commands for the
transaction.
Where using outputs from a previous transaction in a new transaction, counterparties may need to know who the involved
parties are. One example is in ``TwoPartyTradeFlow`` which delegates to ``CollectSignaturesFlow`` to gather certificates
from both parties. ``CollectSignaturesFlow`` requires that a confidential identity of the initiating node has signed
the transaction, and verifying this requires the receiving node has a copy of the confidential identity for the input
state. ``IdentitySyncFlow`` can be used to synchronize the confidential identities we have the certificate paths for, in
a single transaction, to another node.
parties are. One example is the ``TwoPartyTradeFlow``, where an existing asset is exchanged for cash. If confidential
identities are being used, the buyer will want to ensure that the asset being transferred is owned by the seller, and
the seller will likewise want to ensure that the cash being transferred is owned by the buyer. Verifying this requires
both nodes to have a copy of the confidential identities for the asset and cash input states. ``IdentitySyncFlow``
manages this process. It takes as inputs a transaction and a counterparty, and for every confidential identity involved
in that transaction for which the calling node holds the certificate path, it sends this certificate path to the
counterparty.
.. note:: ``CollectSignaturesFlow`` requires that the initiating node has signed the transaction, and as such all nodes
providing signatures must recognise the signing key used by the initiating node as being either its well known identity
or a confidential identity they have the certificate for.
SwapIdentitiesFlow
~~~~~~~~~~~~~~~~~~
``SwapIdentitiesFlow`` is typically run as a subflow of another flow. It takes as its sole constructor argument the
counterparty we want to exchange confidential identities with. It returns a mapping from the identities of the caller
and the counterparty to their new confidential identities. In the future, this flow will be extended to handle swapping
identities with multiple parties at once.

Identity synchronization flow
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
IdentitySyncFlow
~~~~~~~~~~~~~~~~

to require knowledge of which well-known identity each confidential identity maps to. ``IdentitySyncFlow`` handles this
process. You can see an example of its use in ``TwoPartyTradeFlow.kt``.

.. note:: ``IdentitySyncFlow`` works on a push basis. The initiating node can only send confidential identities it has
the X.509 certificates for, and the remote nodes can only request confidential identities being offered (are
referenced in the transaction passed to the initiating flow). There is no standard flow for nodes to collect
confidential identities before assembling a transaction, and this is left for individual flows to manage if
required.
``IdentitySyncFlow`` will serve only confidential identities in the provided transaction, limited to those that are
signed by the well known identity the flow is initiated by. This is done to avoid a risk of a node including
states it doesn't have the well known identity of participants in, to try convincing one of its counterparties to
reveal the identity. In case of a more complex transaction where multiple well known identities need confidential
identities distributed this flow should be run by each node in turn. For example:
Meanwhile, ``IdentitySyncFlow.Receive`` is invoked by all the other (non-initiating) parties involved in the identity
synchronization process:
.. container:: codeset

``IdentitySyncFlow`` will serve all confidential identities in the provided transaction, irrespective of well-known
identity. This is important for more complex transaction cases with 3+ parties, for example:
* Alice is building the transaction, and provides some input state *x* owned by a confidential identity of Alice
* Bob provides some input state *y* owned by a confidential identity of Bob
* Charlie provides some input state *z* owned by a confidential identity of Charlie
Alice, Bob and Charlie must all run ``IdentitySyncFlow`` to send their involved confidential identities to the other
parties. For an illustration of the security implications of not requiring this, consider:
1. Alice is building the transaction, and provides some input state *x* owned by a confidential identity of Alice
2. Bob provides some input state *y* owned by a confidential identity it doesn't know the well known identity of, but
Alice does.
3. Alice runs ``IdentitySyncFlow`` and sends not just their confidential identity, but also the confidential identity
in state *y*, violating the privacy model.
Alice may know all of the confidential identities ahead of time, but Bob not know about Charlie's and vice-versa.
The assembled transaction therefore has three input states *x*, *y* and *z*, for which only Alice possesses
certificates for all confidential identities. ``IdentitySyncFlow`` must send not just Alice's confidential identity but
also any other identities in the transaction to the Bob and Charlie.

Trader demo
-----------
This demo brings up four nodes: Bank A, Bank B, Bank Of Corda, and a notary/network map node that they all use. Bank A will
be the buyer, and requests some cash from the Bank of Corda in order to acquire commercial paper from Bank B, the seller.
To run from the command line in Unix:
1. Run ``./gradlew samples:trader-demo:deployNodes`` to create a set of configs and installs under ``samples/trader-demo/build/nodes``
2. Run ``./samples/trader-demo/build/nodes/runnodes`` to open up four new terminals with the four nodes
3. Run ``./gradlew samples:trader-demo:runBank`` to instruct the bank node to issue cash and commercial paper to the buyer and seller nodes respectively.
4. Run ``./gradlew samples:trader-demo:runSeller`` to trigger the transaction. If you entered ``flow watch``
you can see flows running on both sides of transaction. Additionally you should see final trade information displayed
to your terminal.

1. Run ``gradlew samples:trader-demo:deployNodes`` to create a set of configs and installs under ``samples\trader-demo\build\nodes``
2. Run ``samples\trader-demo\build\nodes\runnodes`` to open up four new terminals with the four nodes
3. Run ``gradlew samples:trader-demo:runBank`` to instruct the buyer node to request issuance of some cash from the Bank of Corda node
4. Run ``gradlew samples:trader-demo:runSeller`` to trigger the transaction. If you entered ``flow watch``
you can see flows running on both sides of transaction. Additionally you should see final trade information displayed
to your terminal.
.. _irs-demo:
IRS demo
--------
This demo brings up three nodes: Bank A, Bank B and a node that simultaneously runs a notary, a network map and an interest rates
oracle. The two banks agree on an interest rate swap, and then do regular fixings of the deal as the time
on a simulated clock passes.
To run from the command line in Unix:
1. Run ``./gradlew samples:irs-demo:deployNodes`` to install configs and a command line tool under ``samples/irs-demo/build``
2. Run ``./gradlew samples:irs-demo:installDist``
3. Move to the ``samples/irs-demo/build`` directory
4. Run ``./nodes/runnodes`` to open up three new terminals with the three nodes (you may have to install xterm).
To run from the command line in Windows:
1. Run ``gradlew.bat samples:irs-demo:deployNodes`` to install configs and a command line tool under ``samples\irs-demo\build``
2. Run ``gradlew.bat samples:irs-demo:installDist``
3. Run ``cd samples\irs-demo\build`` to change current working directory
4. Run ``nodes\runnodes`` to open up several 6 terminals, 2 for each node. First terminal is a web-server associated with every node and second one is Corda interactive shell for the node.
This demo also has a web app. To use this, run nodes and then navigate to
http://localhost:10007/web/irsdemo and http://localhost:10010/web/irsdemo to see each node's view of the ledger.
To use the web app, click the "Create Deal" button, fill in the form, then click the "Submit" button. You can then
use the time controls at the top left of the home page to run the fixings. Click any individual trade in the blotter to view it.
.. note:: The IRS web UI currently has a bug when changing the clock time where it may show no numbers or apply fixings inconsistently.
The issues will be addressed in a future milestone release. Meanwhile, you can take a look at a simpler oracle example https://github.com/corda/oracle-example
.. _attachment-demo:
Attachment demo
---------------
This demo brings up three nodes, and sends a transaction containing an attachment from one to the other.
To run from the command line in Unix:
1. Run ``./gradlew samples:attachment-demo:deployNodes`` to create a set of configs and installs under ``samples/attachment-demo/build/nodes``
2. Run ``./samples/attachment-demo/build/nodes/runnodes`` to open up three new terminal tabs/windows with the three nodes and webserver for BankB
3. Run ``./gradlew samples:attachment-demo:runRecipient``, which will block waiting for a trade to start
4. Run ``./gradlew samples:attachment-demo:runSender`` in another terminal window to send the attachment. Now look at the other windows to
see the output of the demo
To run from the command line in Windows:
1. Run ``gradlew samples:attachment-demo:deployNodes`` to create a set of configs and installs under ``samples\attachment-demo\build\nodes``
2. Run ``samples\attachment-demo\build\nodes\runnodes`` to open up three new terminal tabs/windows with the three nodes and webserver for BankB
3. Run ``gradlew samples:attachment-demo:runRecipient``, which will block waiting for a trade to start
4. Run ``gradlew samples:attachment-demo:runSender`` in another terminal window to send the attachment. Now look at the other windows to
see the output of the demo
.. _notary-demo:
Notary demo
-----------
This demo shows a party getting transactions notarised by either a single-node or a distributed notary service.
All versions of the demo start two counterparty nodes.
One of the counterparties will generate transactions that transfer a self-issued asset to the other party and submit them for notarisation.
* The `Raft <https://raft.github.io/>`_ version of the demo will start three distributed notary nodes.
* The `BFT SMaRt <https://bft-smart.github.io/library/>`_ version of the demo will start four distributed notary nodes.
* The Single version of the demo will start a single-node validating notary service.
* The Custom version of the demo will load and start a custom single-node notary service that is defined the demo CorDapp.
The output will display a list of notarised transaction IDs and corresponding signer public keys. In the Raft distributed notary,
every node in the cluster can service client requests, and one signature is sufficient to satisfy the notary composite key requirement.
In the BFT SMaRt distributed notary, three signatures are required.
You will notice that successive transactions get signed by different members of the cluster (usually allocated in a random order).
To run the Raft version of the demo from the command line in Unix:
1. Run ``./gradlew samples:notary-demo:deployNodes``, which will create node directories for all versions of the demo,
with configs under ``samples/notary-demo/build/nodes/nodesRaft`` (``nodesBFT``, ``nodesSingle``, and ``nodesCustom`` for
BFT, Single and Custom notaries respectively).
2. Run ``./samples/notary-demo/build/nodes/nodesRaft/runnodes``, which will start the nodes in separate terminal windows/tabs.
Wait until a "Node started up and registered in ..." message appears on each of the terminals
3. Run ``./gradlew samples:notary-demo:notarise`` to make a call to the "Party" node to initiate notarisation requests
In a few seconds you will see a message "Notarised 10 transactions" with a list of transaction ids and the signer public keys
To run from the command line in Windows:
1. Run ``gradlew samples:notary-demo:deployNodes``, which will create all three types of notaries' node directories
with configs under ``samples/notary-demo/build/nodes/nodesRaft`` (``nodesBFT``, ``nodesSingle``, and ``nodesCustom`` for
BFT, Single and Custom notaries respectively).
2. Run ``samples\notary-demo\build\nodes\nodesRaft\runnodes``, which will start the nodes in separate terminal windows/tabs.
Wait until a "Node started up and registered in ..." message appears on each of the terminals
3. Run ``gradlew samples:notary-demo:notarise`` to make a call to the "Party" node to initiate notarisation requests
In a few seconds you will see a message "Notarised 10 transactions" with a list of transaction ids and the signer public keys
To run the BFT SMaRt notary demo, use ``nodesBFT`` instead of ``nodesRaft`` in the path (you will see messages from notary nodes
trying to communicate each other sometime with connection errors, that's normal). For a single notary node, use ``nodesSingle``.
For the custom notary service use ``nodesCustom`.
Distributed notary nodes store consumed states in a replicated commit log, which is backed by a H2 database on each node.
You can ascertain that the commit log is synchronised across the cluster by accessing and comparing each of the nodes' backing stores
by using the H2 web console:
- Firstly, download `H2 web console <http://www.h2database.com/html/download.html>`_ (download the "platform-independent zip"),
and start it using a script in the extracted folder: ``sh h2/bin/h2.sh`` (or ``h2\bin\h2`` for Windows)
- If you are uncertain as to which version of h2 to install or if you have connectivity issues, refer to ``build.gradle``
located in the corda directory and locate ``h2_version``. Use a client of the same major version - even if still in beta.
- The H2 web console should start up in a web browser tab. To connect we first need to obtain a JDBC connection string.
Each node outputs its connection string in the terminal window as it starts up. In a terminal window where a **notary** node is running,
look for the following string:
``Database connection url is : jdbc:h2:tcp://10.18.0.150:56736/node``
You can use the string on the right to connect to the h2 database: just paste it into the `JDBC URL` field and click *Connect*.
You will be presented with a web application that enumerates all the available tables and provides an interface for you to query them using SQL
- The committed states are stored in the ``NOTARY_COMMITTED_STATES`` table (for Raft) or ``NODE_BFT_SMART_NOTARY_COMMITTED_STATES`` (for BFT).
Note that in the Raft case the raw data is not human-readable, but we're only interested in the row count for this demo
.. _bank-of-corda-demo:
Bank Of Corda demo
------------------
This demo brings up three nodes: a notary, a node acting as the Bank of Corda that accepts requests for issuance of some asset
and a node acting as Big Corporation which requests issuance of an asset (cash in this example).
Upon receipt of a request the Bank of Corda node self-issues the asset and then transfers ownership to the requester
after successful notarisation and recording of the issue transaction on the ledger.
.. note:: The Bank of Corda is somewhat like a "Bitcoin faucet" that dispenses free bitcoins to developers for
testing and experimentation purposes.
To run from the command line in Unix:
1. Run ``./gradlew samples:bank-of-corda-demo:deployNodes`` to create a set of configs and installs under ``samples/bank-of-corda-demo/build/nodes``
2. Run ``./samples/bank-of-corda-demo/build/nodes/runnodes`` to open up three new terminal tabs/windows with the three nodes
3. Run ``./gradlew samples:bank-of-corda-demo:runRPCCashIssue`` to trigger a cash issuance request
4. Run ``./gradlew samples:bank-of-corda-demo:runWebCashIssue`` to trigger another cash issuance request.
Now look at your terminal tab/window to see the output of the demo
To run from the command line in Windows:
1. Run ``gradlew samples:bank-of-corda-demo:deployNodes`` to create a set of configs and installs under ``samples\bank-of-corda-demo\build\nodes``
2. Run ``samples\bank-of-corda-demo\build\nodes\runnodes`` to open up three new terminal tabs/windows with the three nodes
3. Run ``gradlew samples:bank-of-corda-demo:runRPCCashIssue`` to trigger a cash issuance request
4. Run ``gradlew samples:bank-of-corda-demo:runWebCashIssue`` to trigger another cash issuance request.
Now look at the your terminal tab/window to see the output of the demo
.. note:: To verify that the Bank of Corda node is alive and running, navigate to the following URL:
http://localhost:10007/api/bank/date
In the window you run the command you should see (in case of Web, RPC is simmilar):
- Requesting Cash via Web ...
- Successfully processed Cash Issue request
If you want to see flow activity enter in node's shell ``flow watch``. It will display all state machines
running currently on the node.
Launch the Explorer application to visualize the issuance and transfer of cash for each node:
``./gradlew tools:explorer:run`` (on Unix) or ``gradlew tools:explorer:run`` (on Windows)
Using the following login details:
- For the Bank of Corda node: localhost / port 10006 / username bankUser / password test
- For the Big Corporation node: localhost / port 10009 / username bigCorpUser / password test
See https://docs.corda.net/node-explorer.html for further details on usage.
.. _simm-demo:
SIMM and Portfolio Demo - aka the Initial Margin Agreement Demo
---------------------------------------------------------------
Background and SIMM Introduction
********************************
This app is a demonstration of how Corda can be used for the real world requirement of initial margin calculation and
agreement; featuring the integration of complex and industry proven third party libraries into Corda nodes.
SIMM is an acronym for "Standard Initial Margin Model". It is effectively the calculation of a "margin" that is paid
by one party to another when they agree a trade on certain types of transaction.
The SIMM was introduced to standardise the calculation of how much margin counterparties charge each other on their
bilateral transactions. Before SIMM, each counterparty computed margins according to its own model and it was made it very
difficult to agree the exact margin with the counterparty that faces the same trade on the other side.
To enact this, in September 2016, the ISDA committee - with full backing from various governing bodies -
`issued a ruling on what is known as the ISDA SIMM ™ model <http://www2.isda.org/news/isda-simm-deployed-today-new-industry-standard-for-calculating-initial-margin-widely-adopted-by-market-participants>`_,
a way of fairly and consistently calculating this margin. Any parties wishing to trade a financial product that is
covered under this ruling would, independently, use this model and calculate their margin payment requirement,
agree it with their trading counterparty and then pay (or receive, depending on the results of this calculation)
this amount. In the case of disagreement that is not resolved in a timely fashion, this payment would increase
and so therefore it is in the parties' interest to reach agreement in as short as time frame as possible.
To be more accurate, the SIMM calculation is not performed on just one trade - it is calculated on an aggregate of
intermediary values (which in this model are sensitivities to risk factors) from a portfolio of trades; therefore
the input to a SIMM is actually this data, not the individual trades themselves.
Also note that implementations of the SIMM are actually protected and subject to license restrictions by ISDA
(this is due to the model itself being protected). We were fortunate enough to technically partner with
`OpenGamma <http://www.opengamma.com>`_ who allowed us to demonstrate the SIMM process using their proprietary model.
In the source code released, we have replaced their analytics engine with very simple stub functions that allow
the process to run without actually calculating correct values, and can easily be swapped out in place for their real libraries.
What happens in the demo (notionally)
*************************************
Preliminaries
- Ensure that there are a number of live trades with another party based on financial products that are covered under the
ISDA SIMM agreement (if none, then use the demo to enter some simple trades as described below).
Initial Margin Agreement Process
- Agree that one will be performing the margining calculation against a portfolio of trades with another party, and agree the trades in that portfolio. In practice, one node will start the flow but it does not matter which node does.
- Individually (at the node level), identify the data (static, reference etc) one will need in order to be able to calculate the metrics on those trades
- Confirm with the other counterparty the dataset from the above set
- Calculate any intermediary steps and values needed for the margin calculation (ie sensitivities to risk factors)
- Agree on the results of these steps
- Calculate the initial margin
- Agree on the calculation of the above with the other party
- In practice, pay (or receive) this margin (omitted for the sake of complexity for this example)
Demo execution (step by step)
*****************************
**Setting up the Corda infrastructure**
To run from the command line in Unix:
1. Deploy the nodes using ``./gradlew samples:simm-valuation-demo:deployNodes``
2. Run the nodes using ``./samples/simm-valuation-demo/build/nodes/runnodes``
To run from the command line in Windows:
1. Deploy the nodes using ``gradlew samples:simm-valuation-demo:deployNodes``
2. Run the nodes using ``samples\simm-valuation-demo\build\nodes\runnodes``
**Getting Bank A's details**
From the command line run
.. sourcecode:: bash
curl http://localhost:10005/api/simmvaluationdemo/whoami
The response should be something like
.. sourcecode:: none
{
"self" : {
"id" : "8Kqd4oWdx4KQGHGQW3FwXHQpjiv7cHaSsaAWMwRrK25bBJj792Z4rag7EtA",
"text" : "C=GB,L=London,O=Bank A"
},
"counterparties" : [
{
"id" : "8Kqd4oWdx4KQGHGL1DzULumUmZyyokeSGJDY1n5M6neUfAj2sjbf65wYwQM",
"text" : "C=JP,L=Tokyo,O=Bank C"
},
{
"id" : "8Kqd4oWdx4KQGHGTBm34eCM2nrpcWKeM1ZG3DUYat3JTFUQTwB3Lv2WbPM8",
"text" : "C=US,L=New York,O=Bank B"
}
]
}
Now, if we ask the same question of Bank C we will see that it's id matches the id for Bank C as a counter
party to Bank A and Bank A will appear as a counter party
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" -X GET http://localhost:10011/api/simmvaluationdemo/whoami
**Creating a trade with Bank C**
In what follows, we assume we are Bank A (which is listening on port 10005)
Notice the id field in the output of the ``whoami`` command. We are going to use the id assocatied
with Bank C, one of our counter parties, to create a trade. The general command for this is:
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" -X PUT -d <<<JSON representation of the trade>>> http://localhost:10005/api/simmvaluationdemo/<<<counter party id>>>/trades
where the representation of the trade is
.. sourcecode:: none
{
"id" : "trade1",
"description" : "desc",
"tradeDate" : [ 2016, 6, 6 ],
"convention" : "EUR_FIXED_1Y_EURIBOR_3M",
"startDate" : [ 2016, 6, 6 ],
"endDate" : [ 2020, 1, 2 ],
"buySell" : "BUY",
"notional" : "1000",
"fixedRate" : "0.1"
}
Continuing our example, the specific command we would run is
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" \
-X PUT \
-d '{"id":"trade1","description" : "desc","tradeDate" : [ 2016, 6, 6 ], "convention" : "EUR_FIXED_1Y_EURIBOR_3M", "startDate" : [ 2016, 6, 6 ], "endDate" : [ 2020, 1, 2 ], "buySell" : "BUY", "notional" : "1000", "fixedRate" : "0.1"}' \
http://localhost:10005/api/simmvaluationdemo/8Kqd4oWdx4KQGHGL1DzULumUmZyyokeSGJDY1n5M6neUfAj2sjbf65wYwQM/trades
With an expected response of
.. sourcecode:: none
HTTP/1.1 202 Accepted
Date: Thu, 28 Sep 2017 17:19:39 GMT
Content-Type: text/plain
Access-Control-Allow-Origin: *
Content-Length: 2
Server: Jetty(9.3.9.v20160517)
**Verifying trade completion**
With the trade completed and stored by both parties, the complete list of trades with our couterparty can be seen with the following command
.. sourcecode:: bash
curl -X GET http://localhost:10005/api/simmvaluationdemo/<<<counter party id>>>/trades
The command for our example, using Bank A, would thus be
.. sourcecode:: bash
curl -X GET http://localhost:10005/api/simmvaluationdemo/8Kqd4oWdx4KQGHGL1DzULumUmZyyokeSGJDY1n5M6neUfAj2sjbf65wYwQM/trades
whilst a specific trade can be seen with
.. sourcecode:: bash
curl -X GET http://localhost:10005/api/simmvaluationdemo/<<<counter party id>>>/trades/<<<trade id>>>
If we look at the trade we created above, we assigned it the id "trade1", the complete command in this case would be
.. sourcecode:: bash
curl -X GET http://localhost:10005/api/simmvaluationdemo/8Kqd4oWdx4KQGHGL1DzULumUmZyyokeSGJDY1n5M6neUfAj2sjbf65wYwQM/trades/trade1
**Generating a valuation**
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" \
-X POST \
-d <<<JSON representation>>>
http://localhost:10005/api/simmvaluationdemo/<<<counter party id>>>/portfolio/valuations/calculate
Again, the specific command to continue our example would be
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" \
-X POST \
-d '{"valuationDate":[2016,6,6]}' \
http://localhost:10005/api/simmvaluationdemo/8Kqd4oWdx4KQGHGL1DzLumUmZyyokeSGJDY1n5M6neUfAj2sjbf65wYwQM/portfolio/valuations/calculate
**Viewing a valuation**
In the same way we can ask for specific instances of trades with a counter party, we can request details of valuations
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" -X GET http://localhost:10005/api/simmvaluationdemo/<<<counter party id>>>/portfolio/valuations
The specific command for out Bank A example is
.. sourcecode:: bash
curl -i -H "Content-Type: application/json" \
-X GET http://localhost:10005/api/simmvaluationdemo/8Kqd4oWdx4KQGHGL1DzULumUmZyyokeSGJDY1n5M6neUfAj2sjbf65YwQM/portfolio/valuations

Observer nodes
==============
Posting transactions to an observer node is a common requirement in finance, where regulators often want
to receive comprehensive reporting on all actions taken. By running their own node, regulators can receive a stream
of digitally signed, de-duplicated reports useful for later processing.
Adding support for observer nodes to your application is easy. The IRS (interest rate swap) demo shows to do it.
Just define a new flow that wraps the SendTransactionFlow/ReceiveTransactionFlow, as follows:
.. container:: codeset
.. literalinclude:: ../../samples/irs-demo/cordapp/src/main/kotlin/net/corda/irs/flows/AutoOfferFlow.kt
:language: kotlin
:start-after: DOCSTART 1
:end-before: DOCEND 1
In this example, the ``AutoOfferFlow`` is the business logic, and we define two very short and simple flows to send
the transaction to the regulator. There are two important aspects to note here:
1. The ``ReportToRegulatorFlow`` is marked as an ``@InitiatingFlow`` because it will start a new conversation, context
free, with the regulator.
2. The ``ReceiveRegulatoryReportFlow`` uses ``ReceiveTransactionFlow`` in a special way - it tells it to send the
transaction to the vault for processing, including all states even if not involving our public keys. This is required
because otherwise the vault will ignore states that don't list any of the node's public keys, but in this case,
we do want to passively observe states we can't change. So overriding this behaviour is required.
If the states define a relational mapping (see :doc:`api-persistence`) then the regulator will be able to query the
reports from their database and observe new transactions coming in via RPC.
.. warning:: Nodes which act as both observers and which directly take part in the ledger are not supported at this
time. In particular, coin selection may return states which you do not have the private keys to be able to sign
for. Future versions of Corda may address this issue, but for now, if you wish to both participate in the ledger
and also observe transactions that you can't sign for you will need to run two nodes and have two separate
identities.
