#Note this is a draft copy, improved version coming soon to Steemit

Datacoin - How to Etch an IBM PCx86 simulator to the Blockchain Pt 2 (Applications)


Windows Tutorial

Continuing from the previous guide your simulator should be up and running, it's now time to add some software using the links feature
included with Apertus. Links allow you to use previously etched content stored in the Apertus root index.
The following tutorial will demonstrate how to add a copy of VisiCalc, a trailblazing spreadsheet program
released for the Apple II in the late 1970's. More information on VisiCalc is available below.


1. Create a new folder called ibmapps and add the following files from your ibmjs directory

  index.html
  PCDOSS100.json
  visicalc.json
  components.css
  components.xsl
  example.xml
 
 

2. In your ibmapps folder, open example1.xml in notepad, scroll across and add in the following before line <chipset id..

<fdc id="fdcNEC" autoMount='{A: {name: "PC-DOS 1.00", path: "PCDOS100.json"}, B: {name: "VisiCalc", path: "visicalc.json"}}'/>

This line adds the floppy disk driver component and software VisiCalc

3. You may have noticed that we didn't copy accross a few of the files from the ibmjs folder, we will be using previously eteched
copies which will help us reduce the overall publishing cost.
Soon you be able to work out those savings in VisiCalc Wink


4. Go to your main Apertus directory and open the root folder. Unless you have etched multiple times you should have only one folder
listed if not open each folder until you find the content from the previous tutorial. Click on the folder containing your files and
highlight the long string, select copy. This is the transactoinid that you will be inserting into your new files to create the link.

5. Edit example1.xml in notepad, scroll across until you find an entry for ibm-basic.1.00.json, add / then the transactionid
i.e
6bf7c945623b1571571369769285dd350832703b880fa6978cdfd08db77398d8/ibm-basic-1.00.json

Repeat for
ibm.mda-cga.json
1981-04-24.json



Edit index.html, scroll across until you find an entry for pcx86.js again add / then the transactionid

Save both files.

6. Launch your Datacoin wallet and wait for it to fully sync then open Apertus.

7. You should already have a profile setup from the previous tutorial. Select your settings then
click attach and browse to your ibmapps folder. Select all files using ctrl + a and hit ok.
Providing you have enough DTC in your wallet to complete the transaction, click etch to publish your simulation to
the blockchain.

8. On startup it will display the dos command line, to run VisiCalc simply enter B:vc (no /)

[UPDATE]  The brpwser embeded into http://apertus.io has security limitations that prevent some pages from working properly.  we were so excited to see this work using the shortcut method you worked out above that we decided to save you and everyone a few steps by recreating the same functionality within the browser.   in the lastest release of Apertus v0.3.15-beta, you will see a new button in the top left corner of the browser window. clicking it loads whatever you are currently browsing into your default web browser.

On my Windows surface the edge browser has to be setup as my default web browser to get your example to work.

Thanks for your time.

Hi Embii,

Thanks for checking out the simulator tutorial and for providing this Apertus update.
I prefer chrome as my default browser so this new addition is much appreciated  Smiley

I am running a small ad campaign on Facebook for the next couple of days targeting cryptocurrency
users in the US & Australia. The image provided links back to our main announcement page.
Anyway will be interesting to see the stats when they come back

dtc, IndiaMikeZulu are Australian crypto geeks. I don't hold Datacoin, but it's fine to see a community 'boot strapping' themselves -- I see you have 'no active markets' on Coinmarketcap. EDIT: but you have pop -- gonna have a look at that.

If we can be of small service, PM me -- we have a lot of experience with p2p markets.

The image is only being displayed correctly on one of the display types, so I can
see why people would be reluctant to follow the link.
I am actually more disappointed in the reach figures shown

What is the goal of capitalization of your project?

Our first goal now is just to get it listed on an exchange.  I have no idea what the market will do to the price.

You're on an exchange, extro: BTCpop. I signed up so I could have a look at it. EDIT: But an in-house p2p market would have a bunch of uses!

But from the PMs: I am absolutely superbusy out the wazoo (with another bootstrap project . . . ) But I recall this coin from its launch, and will pop in and watch events.

My Absolute Bottom Line: gotta have click-n-go wallets.

IBM Hyperledger

I see IBM Hyperledger has an asset trading app called Marbles:   https://github.com/IBM-Blockchain/marbles.  
There is a video here:   https://www.youtube.com/watch?v=jhB15Hi_Yok.

There is also a smart contract framework called Chaincode.

We don't have smart contracts and Asset Trading at the moment.  Seems that we could align Datacoin with the Hyperledger framework to quickly gain these capabilities.

Dtc2017 has done some preliminary investigations and believes it is doable.  Lets see how far we get.

Thank you for the support!

Hope you are well loaded up with DTC for the day when the price rises!

Hi Extro,

Here is a fork of the marbles demo
https://github.com/dtc20017/marbles

I am still setting up our blockchain as I want to share accesss across all interested team members rather that running it locally.
IBM Bluemix service offer free trial accounts but they don't include blockchain services and
charge around $1300 per peer. In the mean time we can use my Ubuntu server on google cloud.

I have already emailed IBM Blockchain support for some advice, still waiting to hear back.
Some good news - Hyperledger is definitely compatible with the Datacoin algo.

Also had a look at some of the other technologies under the Hyperledger Framework, Fabric has the most support from industry and is well documented so will stick with that unless you have any objections.

Kind Regards,

A quick update:

I rediscovered Hyperledger composer, using the online testing environment I have been able to create 2 participant types and an asset and then transfer asset ownership from one user to another - all very simple.
then installed ubuntu 64bit and full composer, from the cli I then created a Datacoin test network again with 2 participants and an asset. This can now be published to a .bna file and deployed to a peer.

Integration
I am still working things out but what it seems we can do use the node.js process included with composer to expose the Datacoin test network as a rest api.
Then we can pull data from dtc network and convert that data into assets on the hyperledger network.
I'm still exploring the limits of the testing environment.

cheers
dtc2017


This is very interesting and impressive work by DTC2017.  Datacoin lacks a Smart Contract environment and IBM/Linux Foundation Hyperledger seems to be a good solution.  I don't believe we have the resources to re-invent the wheel, especially as Hyperledger is agnostic w.r..t cryptocurrencies.

I have updated the OP with a link to a fork of the Marbles asset trading application created by IBM Hyperledger.

I have also been busy with Hyperledger Composer Web Playgound:   https://composer-playground.mybluemix.net.
Very nice.  You program your business onto the blockchain via smart contracts.  All is then collected into a .bna file which I presume is then deployed on a server.  Correct me if I am wrong.

So you say the Datacoins will be represented on Hyperledger via a REST API.  With constant communication to the Datacoin blockchain via a local Datacoin client?

Hi Extro,

Yep it works out something like that, there are of course other things you have to do before you
can deploy i.e unit tests but I was just keeping things short and snappy for our forum readers
I highly recommend the main development tutorial which takes you through the entire process in detail.

As for integration I was speculating about how it could done based on what I had
read up to that point, I will probably take a look to see what other blockchains have accomplished
you can see a few listed there on the Hyper members link I posted.

For the moment I am only focused on building our smart contracts platform and trying to
scam a couple of free Bluemix peers from IBM Smiley


BTW - We need a hyper graphic for the OP (you may need to resize)





Cheers,
