Obtaining and Running Graphene
Graphene is Open Source software available on GitHub. The root repository may be found at the Cryptonomex site. There are three projects to be cloned: graphene, graphene-ui, and fc. OCI’s GitHub page includes forks of graphene and graphene-ui, which serve as our research base repository. You may clone OCI’s copy of graphene by visiting
https://github.com/objectcomputing/graphene and
https://github.com/objectcomputing/graphene-ui Comprehensive build and deploy instructions for both kits are included in their respective Readme.md file.
Graphene ships with three executables: the witness_node, cli_wallet, and genesis_util. Once built, you can try running a witness node. Note this example shows how to run the witness node with command line options.

Bitshares was the first Coin to do Tokens, and the Bitshares Tokens are called User Issued Assets (UIAs). The OpenLedger Platform is a Decentralized Exchange Platform, where Nodes are held open by people who are Voted for. So no single person or Company really operates it, it exists on a Blockchain.
Here is OpenLedger
https://openledger.info/Here is the Cryptofresh Blockchain Explorer, which keeps track of the Transactions on OpenLedger.
http://cryptofresh.com/All of that is on the Blockchain.
Here is the OpenLedger Github Repo
https://github.com/bitshares/bitshares-coreBitshares UI
https://github.com/bitshares/bitshares-uiSo, that is the Smart Contracts and the Exchange.
Now, more recently Steemit was made. Which is like OpenLedger, but Social. And it is like Reddit, where you can Vote.

https://objectcomputing.com/resources/publications/sett/march-2017-graphene-an-open-source-blockchain/Steemit is a Reddit Clone, and is limited in that fact. Of all the Social Media Websites on the Internet, Reddit is not really the best example. Reddit is almost secondary. Everyone is either on Facebook, Twitter or Instagram, or all of them. But Reddit is Secondary, like YouTube.
Steemit would do much better as a YouTube platform, where videos are uploaded and earn money, instead of Blogs. We will be launching a YouTube Graphene Clone eventually if someone else doesn’t.
That explains Steemit on a superficial level. I am not saying that Steemit is a failure, I am saying that it would be better if there were a YouTube version.
So secondly, Steemit is a platoform connected to a Coin. There is a backend to Steemit, called Steemd, and you can look at Steemd, just google it. And there are other things, like Blocktrades, which actually connects Steemit and Bitshares. The coin called STEEM, is a DPoWS, which stands for Delegated Proof of Work and Stake.
So let me explain what Delegated Proof of Work and Stake means:
Proof of Work is like Bitcoin and Litecoin and Dogecoin, where everyone Mines with Mining Machines.
Proof of Stake is like Temple Coin or PeerCoin or various other Coins. The way Proof of Stake Works in Steemit, is that anyone that has Coins, has Coins that gain value. And they gain value at a very very high rate the first year or something, then they don’t gain as much after that. And you get coins via Proof of Work, or via Delegated Votes on your Steemit posts, which awards you STEEM from the Blockchain.
Delegated means that the Proof of Work is Voted on, this is done through the “Witness” system. And any Computer or Server or Laptop or anything can be a Node and be a Witness. And Witnesses have the Obligation to Hold Open Nodes, and Mine Coins, which processes transactions and keeps the Blockchain moving. And they get a lot of Coins out of that. Delegated also applies to the Voting on Posts. On Steemit, you get paid when you get Votes, you get paid for Voting (more for posts that end up being popular and you voted early), and you can get votes on your Comments on Steemit. So the Delegated part is important to Steemit.
Here is the Witness page on Steemit
https://steemit.com/~witnessesWitnesses are secretly very important to Steemit, and anyone can become one by being voted for, but they don’t advertise that because they don’t want to get taken over.
So that is the basics of how Steemit works.

At this point, you can use the help command to explore how to use the wallet interface.
Programming with Graphene
The basic API for Graphene is based on remote procedure calls. The specific functions available depend on the terms of the contracts, defined by a particular blockchain instance. A common authentication module is accessed first through the login API. After authenticating, the client application is able to gather other remote object references and make calls to them.
The FC library is used to manage the transport details, allowing the nodes to accept a variety of transport protocols. As currently delivered, the witness_node application is configured to accept HTTP formatted requests. From a C++ application, the Graphene apps library and FC library work together to provide a simple programming model for such access.
Here is an example, taken from the cli_wallet application, showing how to connect to the node server, log in, and make additional calls.
fc::http::websocket_client client;
idump((wdata.ws_server));
auto con = client.connect( wdata.ws_server );
auto apic = std::make_shared<fc::rpc::websocket_api_connection>(*con);
auto remote_api = apic->get_remote_api< login_api >(1);
edump((wdata.ws_user)(wdata.ws_password) );
// TODO: Error message here
FC_ASSERT( remote_api->login( wdata.ws_user, wdata.ws_password ) );
auto wapiptr = std::make_shared<wallet_api>( wdata, remote_api );
wapiptr->set_wallet_filename( wallet_file.generic_string() );
wapiptr->load_wallet_file();
fc::api<wallet_api> wapi(wapiptr);
auto wallet_cli = std::make_shared<fc::rpc::cli>();
for( auto& name_formatter : wapiptr->get_result_formatters() )
wallet_cli->format_result( name_formatter.first, name_formatter.second );
Without getting too deep, what is shown here is that wdata is some collection of initialization information collected from the command line, config files, etc. This is then used to create a client connection, log in (asserting that it was successful), creating an instance of the wallet API that communicates through the authenticated reference to make further calls.
