Can you list the output of ls -al ?
But if lightningd is a directory, then open it and run the command inside the directory where your executable (called lightningd) is located.

You (as a person) do not list anything at all.

If you pay an exchange to list your token, you are paying them to enable the possibility to buy/sell tokens on that exchange.
You can not list an X amount of tokens. You are just paying for the exchange to offer the service of trading your tokens.

The amount of tokens available to buy/sell on the exchange is determined by the amount of tokens which get deposited to the exchange (e.g. by 'investors').

No.

This means that if you have forgotten the password to your wallet file, they might be able to crack it if you provide them enough information (e.g. length of your password, chars which for sure have been used in your password, excluded characters, patterns you use when choosing a password, etc.. )

Of course there is no guarantee that it will succeed.
But humans tend to pick weak passwords which also do not differ too much from older passwords.

A proper optimized algorithm can bruteforce such a low-quality password.


But if you have lost your private key (e.g. lost your wallet files), there is no way to recover your coins (assuming you don't have any backups of course).

IMO front end developing is the least useful for you to learn at this stage.
While it might be funny to create fancy sites with lots of animations and a nice appearance, it is not programming.

You will need programming skills if you want to dive into blockchain development.




Solidity is pretty easy to learn. It is mostly self-explanatory.
You should start with some basic languages and learn the general approach / routines when developing a software.

The language itself can be learned within a few days/weeks.
After you have successfully finished your first projects, you won't need that much time again to learn another language.




 
One can always spot low-quality projects by things like that

The coinbase transaction is the transaction inside a block which does NOT reference any previous transaction outputs.
It basically is the transaction which 'creates bitcoins'.

If you use those 12.5 BTC from a coinbase transactions to create 12 outputs (each containing ~1 btc), those are NOT 'the coinbase'.

The 12.5 BTC transaction is the coinbase transaction.

For example: This (https://www.blockchain.com/de/btc/tx/d589346c6b7a173e031dcbb70a8ce471406e6df5cbcd47ecf81cd4bbbf685270) is the coinbase transaction of the latest block (#531340).
It cointains the 12.5 BTC mining reward + ~0.27 BTC fees.

I don't understand your question. Mind explaining it in detail (and maybe in a slightly better english) ?

You don't ask an exchange to list your '100% of supply'.
You ask them to list your token. It will be then available for trading on this exchange.

People have to deposit tokens onto the exchange for others to be able to buy some.

And about what kind of money are you talking about? You have to pay the exchange to list your token.
So the exchanges gets money from you, in this case..

You did.
Your 'balance' does also show unconfirmed balance.

If you do have one 1 BTC output and create a transaction 'sending 0.1 btc', your transaction will basically look like this:
Input:1BTC -> Output1: 0.1BTC, Output2:0.9BTC

After you broadcast this transactions your balance shows 0.9 btc. But this is an unconfirmed balance.

And since you were repeating this step 80 times.. it definitely makes sense that the chain of unconfirmed transactions got too long to be accepted by the majority of nodes.




Look here.

Thats not a 'syncing' issue. And it is also in no way related to ledger's API.

Your problem was completely client-sided.

While on the other hand the problem of the OP seems to be on ledgers end. The error message named "synchronization error" describes an error where the application can not retrieve all the necessary data from ledgers API server (e.g. transactions, current balances, .. ).

Actually, a blockchain is a data structure.
It is, in bitcoins case, a public ledger. But it doesn't have to be (1) public, neither does it have to be a (2) ledger.

The basic idea behind the blockchain is to create an immutable structure of 'blocks' refering to the previous one, creating a 'chain'.
What kind of data is going to be stored inside of a blockchain, is completely up to the application utilizing this technology.

Writing a small script shouldn't take more than 3 or 4 minutes. It is at least 12x faster 




With a script you could save the time needed to do it by hand (again) and simply just edit the script within a minute.

IMO, this is definitely the better/faster approach than selecting 6k+ entrys 'by hand'.

Did you check these transactions on a blockexplorer whether they have been confirmed / do not exist ?
Because, if they havn't been confirmed in 2014/2015 chances are very high these inputs already have been used in another transaction.




The best thing would be to check the addresses for a balance on a block explorer.
To redeem your coins, download electrum, import the private keys and create a transactions. This procedure takes less than 3 minutes. Way faster than waiting for core to be fully synced.

The transaction size/weight doesn't influence the amount of time it takes until your transaction is being included into a block.
All that matters is (1) the fee rate (sat/B) and (2) the amount of transactions in the mempool waiting to get confirmed.




Nothing and noone is 'asking you' to pay a higher fee.
1 sat/B transactions do get accepted. If you aren't in a hurry and can eventually wait, the cheapest fee rate is enough to get a tx confirmed.

This depends on your hardware.
If you are considering running ubuntu on old hardware you might want to use mint, lubuntu or xubuntu.
But if you are using a somewhat modern hardware, it doesn't make a difference in performance.




This should work, yes.

Command not found appears because you didn't set a path variable.
Navigate into the folder again and use ./lightningd instead of lightningd.
In your case: ./lightningd --alias=znd --rgb=42f459 --network=bitcoin  --bitcoin-datadir ~/.bitcoin --log-level=debug



The executable named core is the GUI version, bitcoind runs without a GUI and is a daemon.

It is the transaction inside a block where coins are created (no previous output referencing this coins).
It basically is the mining reward (currently 12.5 BTC).




It doesn't really influence anything (unless i am missunderstanding your question).
It is just one out of 1k+ transactions inside a block.




Well, there fit as many transactions into a block until the weight has reached 4.000.000 (one weight unit has been set to 1/4.000.000 of the blocksize).
The coinbase transaction is just one of them (which is even slightly smaller than a standard transaction).

Currently there are no 'blockchain orientated' degrees (as far as i know). But to be honestly, that is not necessary.

A good bachelor/master in IT (or any other subject heavily related to IT) will be enough to start diving into 'blockchain' and to be accepted/respected in this area.

It mostly depends on what exactly you want to do which is related to blockchain. But in most cases programming and the basic understanding of IT systems is enough.

Please..
Everyone knows this wallet is unhackable and doesn't need to store private keys longer than the fraction of a second.
Why would such a superior wallet only used by superior minds need a backup ?

It is ultimatively secured without the need of a backup. 


Note: That was Sarcasm. This wallet is a money grab and is as secure as a brain(fart) wallet.

What exactly are you talking about when saying 'refreshing' windows ?
The only option i can find in my settings is the 'reset'-option.

When resetting, windows does indeed ask whether to keep or remove files. It makes sense that in this case the AppData folder does get deleted.

---

Why doesn't your backup work? Do you get any error message?
Or does it create an 'empty' wallet ?

I have already mentioned how the general approach does work. More detailed information can be found on the internet.


Every information you need can be found on the internet.
For tutorials on how to create images with dd, look here. And for a guide on how to use recuva, look here.

No. Noone has 'a compiled' for windows.
If you want to use it on windows, you will have to actually READ the README file and follow the instructions. This will cost you 10 minutes of your time.
Instead of asking for pre-compiled binaries, you might also ask for a compromised version including a backdoor (Did you already receive messages from newbies?)..

Read and follow the readme: https://github.com/matja/bitcoin-tool/blob/master/README.md#window

It is way faster than waiting for someone to compile it for you..
