This type of invention is expected when cryptocurrency is getting bigger, i read the article and it stated the platform in already available on ledger wallet.
Is this project centralized or we just misunderstand them because they claimed not to hold user private keys?
Even now that there is no undo button for transactions, a lot of people are still being scammed because they sent their money to a scammer or they sent to a wrong address.
Sending to wrong address doesn't means you got scammed, it's stupidity.
Not in a situation of someone whose computer was attacked by copy clipboard hijack.
That's why it's better to request for both qr code and wallet address of sender when sending a transaction. All you need is two devices, a PC and a mobile phone that you're going to send the coin from.
Thats still a better option but most of us dont usually request for the qr code.
Anyone can recover lost coins by creating Hardfork, but will the entire network be forced to follow, no.
You can take back all your currencies or even create a new transaction with thousands of currencies.
The value of these currencies will be zero because no one will want them.
If this happens to Bitcoin, its value will be zero.
I don't understand what you're to say here but the hard fork has nothing to do with recovering of lost coins and aside from the platform discuss on this thread the other option to recover lost coins is through double spending when the transaction is yet to be confirmed.
