most certainly however your context may differ from others as to how the blockchain is used.

if the piece of music contained a certain note structure where there was 1 answer to the question, the answer could be hashed so as not to give away the text based answer. this answer would be published on the blockchain for all to see wet her it was correct or not.

your other method of reward would be a payment ledger which is what our beloved bitcoin is, its a DL of payment transactions.

not sure how you would implement it in your case to record and answer and issue a payment but i guess it could be possible.

My use is not so complex its just a ledger of users issued certificate.

I believe Lightning Network derived HTLC or hash time-locked contracts could do this, however it in itself is complex.

In a nutshell it involves 2-3 parties that have a hash of their own and each user adds their hash to complete the transaction based on another users hash. Within this contract there is a condition to be met, in your case it could be that their answer must equal the same hash and thus the correct hash answer releases a reward. Their is also a time component where if the user fails to meet the hash outcome within a specified time the reward is cancelled, or if someone cheats they are forfeited. Again this is just my gleaned and brief understanding.

I am still in the early days of LN and HTLC, but its something i am currently setting up. I am working on my own LN channel as i type.

Lots to learn and we are still in the early days of Bitcoin derived blockchain and DLT. Have fun.

I am using this as basic tracking of certificates of completion for an education and training system i am working on.

I am basically just storing the cert hash on the blockchain. That certificate hash is made up of the users details then added to the chain.

The next step is auto integration where when a user completes the training in that very instance it is added to the chain instantly. Small steps but i find blockchain and DLTs fascinating, hence being here.

Not many people like the command line aspect, some dont like the API aspect. My sentiment is dont let the unknown defeat you, attempt learn what you dont know now and ease into it. Its how most / every person learns new things.

I know we have an enormous experience base here on bitcointalk.org so i plead with more advanced users not to berate or flame newbies. I welcome them as thats how i started myself.

Good luck and remember if you are really determined you will accomplish most things, if not all things you are passionate about.

You could also want to build some small centralized blockchain for your small project or even of some company, limitations are endless. Building blockchain is not strictly tied to building next altcoin as money is just one application that can be built on top of it.

You can try checking out some of the stuff on Coursera. I just started this one tonight so can't vouch for it in any way.

There are a few others there too on Cryptography.

if you have all the resources you need you can get started now i have seen many situations where other steel an idea from the original owner of it an airdrop case for instance in the name of litecoin a lot of them were claiming the same name the real one was forced to rebrand it is name to ELTCOIN so it is possible to have the same name your idea may be stolen.

Hello to everyone here

I am new with mining, I am doing it just for fun on my rig some time now.Everything is fine but one thing. When using wallet cli I get balance 0 and pending balance 0.Is there some bug or I am doing something wrong? I did everything step by step, I tried admin privileges,tried everything.And is there an online way to see my wallet balance?

Thanks
