Syllabus the first steemit workshop in Lhokseumawe, Aceh, about the introduction of Blockchain, Cryptocurrency, and digital investment opportunities. I gave this open lecture to all the participants who had attended on Saturday evening, March 24, 2018, at the VVIP restaurant meeting hall "Ayam Penyet Pak Ulis". Participants come from various backgrounds, entrepreneurs, students, lecturers, academics, local government, and religious observers.
The activities went smoothly and conducive, the participants were very enthusiastic and interested in the material delivered.
I acknowledge that there are still many shortcomings in my course materials, and also because time constraints cause me to press every point of submission, I also know that I find it difficult to find the appropriate language equivalent to interpret some points of discussion so that there are some participants who have difficulty digesting.
I deliberately publish my lecture material so that for the future participants and the steemit community, in general, can develop and complete the course material.

KEYWORDS
- Blockchain
- Cryptocurrency
- Investment
BLOCKCHAIN
- The ledger that records every transaction and continues to grow, the book is called a block, each block is connected and secured with cryptography
- Blockchain using cryptocurrency was discovered in 2008 by Satoshi Nakamoto (anonymous)
- Blockchain 1991 was once used by Stuart Haber and W. Scott Stornetta to send messages
- Blockchain uses a decentralized system (not centralized)
Cryptography
- Derived from greek (kryptós and Graphein which means Kryptós = hidden/secret
Graphein = to write - Previously used by spies to convey messages

Public-key cryptography, where different keys are used for encryption and decryption. Image source wikipedia
Message translator
Transaction
Blockchain simplification
- The ledger containing the note (block = book)
- Each book has a capacity (more than 30GB or less)
- It takes 4 seconds or more to create a new book/block (Depending on the built system)
- The recording will continue (after 4 seconds or more) on the next book/block
- Each book has a unique code, and is related to previous books
- Those who record and provide books are accountants (miners or witnesses in steemit)
Blockchain Scheme
CRYPTOCURRENCY
- Cryptocurrency can be used as a digital asset and is created as a means of exchange that uses cryptography to secure transactions
- Can be created limited or not
- Can not be intervened
- Can be owned by anyone
- Not legally recognized as a medium of exchange in Indonesia
INVESTMENT
Where?
- Creating a new cryptocurrency (altcoin)
- Being miners/provide services (in steemit, miners are also called witnesses)
- Collecting/stockpiling cryptocurrency (in steemit, increasing steem power-SP)
- Merchant (conventional money exchange service/IDR/USD etc.)
When is the price of cryptocurrency rising/expensive?
- Nobody knows
- The more market demand is likely to increase (economic principles)
Investment = accept the risk of failure 99%
- Very high fluctuations
- The analysis is just an opinion
- No one is responsible
- Vulnerable fraud and abuse
- Must understand the system
- Very dependent on the network (internet)
Steem Prices from 18/4/2016 to 24/3/2018 (IDR)
- April 18, 2016 steem price = Rp 8,490.-
- Steam price March 23, 2018 = Rp 27,072.-
- April 18, 2016 to March 23, 2018 = 704 days
- Lowest price of March 11, 2017 = Rp 962.-
- Highest price January 03, 2018 = Rp 110,473.-
Finally, I have to analogy every point of the matter, blockchain, cryptocurrency, and how to invest.
In fact, I have much to say, and I should also make sure the audience can digest every point of matter that I preset to be useful in the future, and finally. because of the limited time then the matter I stop and solid until it's there, then I will have a personal discussion with the participants.
Thanks to @pakulis who has sponsored this workshop (without you this workshop may not materialize), thanks also to colleagues who have worked to succeed this workshop (@saifuelbahrie, @azirgraff, @teukumukhlis, and @jumaidafajar) also to all journalists who have attended the event.
