Day #3 and #4 of Creating Private Blockchain Workshop 🙂
Today we develop a blockchain implementation for election/voting 🙂
Election Results 🙂
The code
The class
Setting up for vlog 😀
After class
Having big headache LOL
*Photos and videos are also available here
We’re ready to create our private blockchain today 🙂
Mbak Ayu from BDV is opening the workshop 🙂 Thanks to BDV for providing us with everything: classroom, internet connection, lunch and great opportunities to learn together 🙂
Now Blockchain opportunities 🙂
How transaction is performed and recorded
A simple blockchain demo
The class
Some screenshots of what we did in class 😉
We can do transactions and even stealing each other ether 😀
A big leap today 🙂 Going to learn how to do voting with blockchain on the next class 🙂
*Photos and videos are also available here
OK, Day #2 of Minecraft Modding Coding Camp 🙂
Today kids did more coding, they typed lots of lines and then execute it in Minecraft 🙂
We created lots of structures, starting from piles of blocks to bridge, tunnel, skyscraper, igloo, pyramid, triangles and so much more!

Aidia taught Gazka how to create a roller coaster in Minecraft (behind Capt. Faris was creating the JavaScript coding version :D)
And this is our Blockchain coding research with Python in the background 😀 Capt. Faris was busy improving the code 😀
Lots of coding and progress today, tomorrow kids will be working in groups and be given challenge 😉
Hello 🙂 This week kids are getting better coping with the fasting 🙂 Less whining and more working 😉
Vian was still experimenting with command blocks as usual 🙂
And Nadine started to add button to activate a LED
The code 
and worked just fine 🙂 
The next project is adding one more LED 
The first LED will be turned on each time we press the button in short time 
When you push the button for longer time, the second LED will be turned on 
The code 
Koosha brought his own project 
Koosha wanted to control a circuit via Discord, with Python 😉 We did lots of debugging to this code and found some version incompatibility, problems with libraries and many errors 🙂 
We still need to figure things out because we still cannot install one of the library in Python to connect Discord to the outside world. We’ll work this out next time, don’t worry Koosha 🙂 
Firaas learned GameMaker and Minecraft Modding today 
This the latest version of Firaas’ PacMan Game 🙂
So typical of Firaas 🙂
Neat and interesting as always, and Firaas was given a homework to start his own Agario Game 🙂 
Sam was struggling with making Agario work 🙂 
There are still some bugs, but that’s how we learned: how to take those bugs down one by one 😉
Capt. Faris spent half of the time gave a undergraduate student tutorial about tensorflow
… and the other half to explore blockchain coding in Python 🙂
Faris had learned how to modify the genesis and the mining process and many things in the code
The number of attempts to get the required hash function
The chain
Fadhlan forgot to bring his laptop and some of the essential parts needed for the project so he just continued attaching things to the robot 🙂 In the picture: connecting wires to the servo
This is how Fadhlan brought his stuff to the class OMG 😀 He seriously needs a toolbox (a big one) 
He also got most of the components in the box contaminated with superglue! 
Ain + his command blocks projects: a big smile 😀
Fathan’s Agario started working 🙂 Still struggling with the code, just like Sam 😀
Nafis forgot to bring his robot, so that he was given a task to control micro servo via cloud so later he can apply it to the robot 🙂
He brought the toolbox so there are enough micro servo to be tested 😉 
This is how ProCodeCG Kids learn: by solving problems, by being challenged, by working in a team and by following their intuition and curiosity 😉
Will be reporting again soon 🙂
ProCodeCG attended IBM Hyperledger Blockchain Workshop yesterday 🙂
The agenda
Not many people have the opportunity to learn this 🙂
The trainers 🙂 From left to right: Pak Andre Jenie, Mas Aldred and Mba Janice 🙂
Taking notes 🙂
Some of many screenshots we did yesterday 🙂 We finally successfully build a to do list on HLF 🙂 Can you imagine a to do list on a blockchain platform? This is it 🙂
on the left, the transaction on the chaincode
Soon ProCodeCG will give training about this topic, probably for kids too 😉
ProCodeCG codeMeetUp() #111 🙂
Philosophy of Blockchain by Prof. Budi Rahardjo 🙂
Blockchain is not equal with Bitcoin
Example of transaction
how miner work
initiating amount of bitcoin for A and A send some to B
A chain will be created for each transaction
The transaction will be hashed with certain criteria
Example of simple hash
A demo of transaction recording and creating chain in PERL
creating hash that meets criteria for each transaction
the code: generating chain, calculate hash, etc. Showing how mining is done
How miner work
Summary
The audience
We had long discussions 🙂
Thanks for coming 🙂
See you on the next ProCodeCG codeMeetUp() 🙂
Today, we had Founder of Exclusor, Tata Tricipta, sharing about CryptoEconomics on ProCodeCG codeMeetUp() #108 🙂
About Exclusor (from the WhitePaper):
“Exclusor introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. Reducing energy consumption and high cost in block creation, thus lowering the customer fee unlike current blockchain transactions. This can be achieved by implementing new consensus algorithm and deploying consortium network model.”
We set up the room while waiting for more people to come 🙂
This is a very recent topic involving cutting-edge technology 🙂
Introduction about Blockchain
The ecosystem
What is cryptoeconomics?
Implementation of cryptoeconomics
Exclusor protocol
Exclusor Decentralized Autonomous Organization
IDAEX
Some notes
and some more
The audience
Us 🙂
QA Sessions and discussion after the presentation 🙂
