Taking bitcoin aptitude tests, and other cryptocurrency tests is a totally great idea, and one that should be abducted by investors in the system, especially newbies. this will help test your knowledge of the system, and indirectly broaden your knowledge. With tests likes these, you will be able to know how well informed you are about the system and where you would have to improve your knowledge.

Thank you for the feedback. We are looking to improve our offering.

After you register the hyperlink for Unit 1 should be available. Click on it to begin the course.

I did... and there's still no hyperlink available. Shows the course, the Unit 1 and 2. But no hyperlink. It shows me my username so I think the registration worked. Funny thing is I didn't get any confirmation email in my inbox used to register though. Maybe that needs to happen and I need to verify first?

Anyone else tried with success? Purely out of curiosity for me.



After you register a new account, the Bitcoin Aptitude Test should automatically be made available to you. Let us know if you have any troubles and we would be happy to assist you.

OK so I tried registering. Just for the heck of it. Curious to see what a commercial test would rate me in terms of aptitude (just Bitcoin right?).

Anyway, once you register and are logged in, you can't click on any part of the Aptitude course. It just shows me a table, with the 1 module and 2 units. Can't enter, can't click can't anything. No test to take.

After you register the hyperlink for Unit 1 should be available. Click on it to begin the course.

You should confront your doctor directly. Nothing better than a yelling match in the hospital halls.

Ask him if he was smoking. If he doesn't answer with a clear answer get right up in his face. Don't be afriad to raise your voice and start jabbing him in the chest with your index finger.

Be strong. Show him who is boss.

Shake your head as you leave his office cursing under your breath.

Over the past couple weeks, our team at Diginomics Corporation has been putting together an online tutorial on How To Fork Bitcoin. Although the course is still in development, and will be released gradually, lesson-per-lesson, over the next couple weeks, I wanted to make an early offering to the people of bitcointalk. The first lessons are available immediately with the following lessons to come online in the next few days.

For the first 21 people who use the code 'Xrs3&2sde' registration into the course is absolutely free. For those who use the code afterwards, a discount of 15% will be available with the code. You also get an additional 10% off when you pay in bitcoin.

We designed this course for the people who are interested in forking bitcoin to begin mining a new chain or creating their own cryptocurrency from genesis. This course allows you to:

  • Understand how forking works
  • Set up your development environment and fork the bitcoin core repository
  • Introduce technical customizations to the blockchain

We have also designed a support forum for students that is available for questions about any of the courses. Instructors check into the forum periodically to answer questions and post updates. Please take a look at the support forum.

If you have any feedback for the course please contact us directly or leave it in this thread. Once again, bear with us as the course content is updated (written tutorials, video screencaps, and timed examinations).

Thank you for reading and we look forward to seeing you inside the course!

First of all, I wish you success in your new initiative. But there will be a general criticism. We've spent 2 years on the fork. Everybody knows about Bitcoin Cash, but there are so many Bitcoin forks in the market that you'll be amazed at once.

Here is the part I will criticize. We don't need any forks on bitcoin. I don't even think we need a fork on any network. I think that only fork can be accepted for system upgrade. I advise you to be more sensitive about this.

I'm sure your training programs will be useful. I hope you'll be very successful.
If you will allow me to answer your query and concern ...

It is true that there are numerous forks of bitcoin on the market today but we do not see this as a sign that "we don't need any forks", but rather that there is a clear market demand for forks. Additionally, forking bitcoin does not necessarily pose a threat to it but challenges its robustness and makes it more resiliant to compeititon.

It is good if there are many forks of bitcoin because it demonstrates that the technology is useful. We should be worried if there were exactly zero forks of bitcoin.

48  Bitcoin / Bitcoin Discussion / Will Bitcoin Lead to the SIngularity? on: April 20, 2019, 06:03:15 AM
In 1993, professor Vernor Vinge of San Diego State University, published a paper predicting a point in the near future where technology itself would be capable of creating greater-than-human intelligence. This point, Vinge characterized, would see large computer networks and their associated users “wake up” as superhumanly-intelligent entities. In such a scenario, technology would be capable of improving upon itself in such rapid succession, that from the purely biological perspective, it would be seen as an “intelligence explosion”. This future point in time at which technological development irreversibly changes the conditions of human civilization, has come to be known as ‘The Singularity‘.

“This change will be a throwing-away of all the human rules, perhaps in the blink of an eye — an exponential runaway beyond any hope of control.

It’s fair to call this event a singularity. It is a point where our old models must be discarded and a new reality rules, a point that will loom vaster and vaster over human affairs until the notion becomes a commonplace. Yet when it finally happens, it may still be a great surprise and a greater unknown.”

– Vernor Vinge, Technological Singularity


Due to the rapid progression of fantastically powerful computer networks, this point of no return, the technological singularity, now appears more accurate and imminent than ever. The bitcoin network, for example, has demonstrated exponential growth in total hashrate since it first came online in 2009.


The uniqueness of the bitcoin network, and the manner in which the blockchain verifies large quantities of data, creates the perfect application for artificial intelligence to make sense of communication patterns (transfers of value) which appear seemingly unrelated to the untrained eye. Artificial intelligence will be capable of performing fantastic analysis of the data time-stamped into the bitcoin blockchain. These analyses will give rise to astonishingly accurate predictions.

One of the most intriguing developments in the bitcoin industry is the growing trend of forking. With this practice, individuals can inherit the technology of the original bitcoin implementation (bitcoin core) and introduce new technical specifications and parameters running on an entirely new software ecosystem. Already, many new “versions” of bitcoin have been created by forking the original source code. Many of these new implementations have targeted increased payment scalability and additional software use cases (such as the addition of a turing-complete scripting language). In this course, we will guide the student on how to initiate a hard fork of the original bitcoin core implementation in order to create their own adjacent (and completing) blockchain.

Tutorial: How To Fork Bitcoin

This course is of particular interest to individuals:

  • creating their own cryptocurrency for investment and profitability potential
  • bringing new use cases for bitcoin and cryptocurrency to market
  • proposing methods to sustainably scale the bitcoin payment network

In this course, we will complete a “bare essential” hard fork of bitcoin core – meaning that we will target an upcoming block on the network timeline and create a parallel network with little or no new modifications to the source code.

After we have familiarized ourselves with this procedure, we will attempt more advanced implementations such as:

  • alternative scaling methods (increasing the average block size and block data limit)
  • introducing a turing-complete scripting language to the blockchain platform (Solidity/JavaScript) for programmable applications
  • Examining and enabling previously disabled opt-codes (done for security purposes in the early stages of development)

Please note that this area of bitcoin research and blockchain development is at the cutting edge of industry. Therefore, we advise leaving room for making mistakes and also ask the student to understand that there will be many modifications to the course instructions contained within. Many courses available today in the bitcoin and blockchain industries target the programming of bitcoin but fail to deliver on how and why a developer may wish to experiment with these new internet protocols.

In this tutorial on How To Fork Bitcoin, we will show the user not only how to create and run their own parallel network, but why we believe forking the existing software repository of bitcoin will be one of the prime opportunities for bringing new applications to market.

In the world of bitcoin, I wanted to see what people are most interested in learning about. Here we have presented a few options to get a better feel for the community here on BitcoinTalk. Please select which topic you would like to learn more about as we continue to develop bitcoin and cryptocurrency.
51  Bitcoin / Bitcoin Discussion / Introductory Course On Bitcoin & the Blockchain on: November 11, 2018, 09:34:05 AM
Way back in late 2012/early 2013, when I first heard about bitcoin, my immediate inclination was to jump on my computer and search "bitcoin forum". Naturally, this brought me to BitcoinTalk where I remain an active poster today. That 2012 query has completed changed the course of my life as well as my financial status. It has been show to me that the best place to learn deeply about a subject, when there are no other available options, is an online community.

BitcoinTalk was and still is that community for me and today I would like to express my gratitude.

If you are someone who is interested in learning more about bitcoin on a deep level, and considering the implications of digital money, I encourage you to take a look at our Free Introduction to Bitcoin Course.

It has already been well received by the community and we would like to continue further development on it. Students who are enrolled today will have the course content made available to them as long as we continue to update the materials.

I am hoping to get some valuable feedback on this course.

Thank you all and good luck!

Bitcoin is digital currency and it is decentralized and peer to peer network. If we introduce it in a paper currency it won't be decentralized. So the idea may good but it decreases bitcoin popularity.

The idea is to have a physical currency that is also redeemable for bitcoin. The physical aspect of it would require a centralized issuer.
53  Bitcoin / Bitcoin Discussion / Re: How To Issue A Paper Currency Backed By Bitcoin? on: November 11, 2018, 03:27:48 AM
It’s called Casascius coins and it’s illegal (without expensive licenses).

https://en.bitcoin.it/wiki/Casascius_physical_bitcoins

“As of Nov 27, 2013, Mike Caldwell suspended sales of items that contain digital bitcoins. The Financial Crimes Enforcement Network (FinCEN), a branch of the Treasury Department, informed him before, that minting physical bitcoins qualifies him as a money transmitter business, which means he needs to register at the federal level and probably get state licenses too.”

And I assume the legal requirements are similar in other countries.

Quote from: Paleus link=topic=5067124.msg47780957#msg47780957
The authority presents their public key, prints a cryptographically signed message on each note in the form of a QR code, and promises that it will be redeemable for 0.0001 BTC?

How would it be redeemed? Is a fixed exchange rate necessary? Why not print the private key on the note itself? If the paper currency is directly redeemable for 0.0001 BTC, than why not simply use bitcoin itself?
1.Through The Bitcoin Note Issuer.
2.Yes It Necessary,To Ease The Transaction.
3.It Would Make The Paper Note Single-Use,Unless Somehow You Can Make A Change Between Redeemed And Unredeemed Note.(Maybe You Can Copy The Gift Card Mechanism)
4.For Offline Transaction.

The main purpose for printing it on a physical paper note would be for offline transactions. We do not want to require everyone to carry around with them a mobile wallet. Therefore a physical, paper currency could work.

Eventually however, the ledger held by the issuing authority would need to verify their balances into the blockchain for the public to see. This could be done by embedding the data of the ledger into the blockchain (or even coinbase). The formatting would be in a manner that takes advantage of compression and also possibly in an encrypted manner that is revealed only to those who hold the necessary decypher key.
56  Bitcoin / Bitcoin Discussion / Blockspace Is the Commodity of Bitcoin on: November 11, 2018, 02:23:30 AM
Read original research: https://diginomics.com/2018/11/10/blockspace-commodity-bitcoin/

When an individual makes a transaction on the bitcoin network, no actual currency is moved. That is – no file has moved, no commodity or asset has moved, no private or public key has moved. Rather, the only thing which changes is the percentage of the blockchain ledger which User A & B claim control over.

When a transaction occurs in the realm of bitcoin, the image of the blockchain is altered. Nothing ever changes but the composition of this blockchain record. The blockchain is a historical record of its ownership. It is a downloadable file (.dat) which began at zero and is now ~ 189 gigabytes (GB) in size.

There is no separation to be made between the blockchain and bitcoin. They are one in the same. Without the blockchain, you have no bitcoin ecosystem. Without an accompanying cryptocurrency, you have no measuring tool to determine the ownership of the blockchain. Money is now an image, rather than something which can be separated from the system itself. This image of money is being constructed by machines acting as miners across the globe. The miners are the painters of the blockchain image.

On the bitcoin network, money is an image continuously being generated (coinbase), re-attributed, and verified by way of cryptographic authorization – the application of numerical law.

The commodity of bitcoin is blockspace – that is, space within the blockchain where data can be timestampped and verified into existence through the decentralized network of computers who are contributing their labour (hashing proof-of-work) in order to propagate the next iteration of the blockchain record.

Each hash performed by a bitcoin miner produces a random number between 0 and the maximum value of a 256-bit number. The SHA-256 hash of a block's header must be lower than or equal to the current target to be accepted by the network. If not, miners increment the nonce (completely changing the hash) and try again. This is the contributed labour that all miners contribute to the ledger of bitcoin.

The process of verifying information into the blockchain is the work performed. Each unit of bitcoin gains its value from the amount of work (hashpower) that went into solving the latest block.

Blockspace is the commodity!

You can do as you described - provide a cryptographic signature on every banknote to somehow prove that the banknote is backed, but what's the point really? It all boils down to a centralized entity that holds the coins and exchanges them on demand, so you can skip the signature part and just issue paper notes and provide proof separately to auditors or the public by showing your cold wallet addresses and signing some message.

The authority presents their public key, prints a cryptographically signed message on each note in the form of a QR code, and promises that it will be redeemable for 0.0001 BTC?

How would it be redeemed? Is a fixed exchange rate necessary? Why not print the private key on the note itself? If the paper currency is directly redeemable for 0.0001 BTC, than why not simply use bitcoin itself?

59  Bitcoin / Bitcoin Discussion / How To Issue A Paper Currency Backed By Bitcoin? on: November 11, 2018, 01:07:36 AM
Let's say we had a bitcoin wallet with exactly 1.0 BTC in it. We wanted to use this 'reserve' to issue your own physical, paper currency.

This could come in the form of a bond or security. The necessary thing is that it must be tradable, counterfeit proof, and hold value.

If we printed a circulation of this paper currency, perhaps we could call it a note redeemable for bitcoin within the wallet at a fixed exchange rate.

1 Physical Note = 0.0001 BTC

It would seem that a signature from the private key of the reserve wallet would be required to produce a QR code which can be printed on the physical note. Each note must be signed cryptographically.

When the note is presented to the authority, it is redeemed from the bitcoin wallet to the customer?

How could such a system work?
