This question is open for invention. A blockchain can have no money at all. People can just play games on it and everyone will agree on the objective history of all games played. For example, you can assume that there is a fixed amount of m

If you are the manufacturer, who already know the root private key and can make some fake users, you still won't be able to print new money from nowhere. Yes, you CAN make double spending, but this will just split the network, because

If his vote is not decisive then yes. But, in theory, a vote of the representative that has low stake can be decisive. The commitment of two conflicting votes can split the network, thereby ruining it.

NANO has delegated Proof-of-Stake. It's the representatives who vote on transactions. And it's supposed they don't have incentives to ruin the network. It's true, but a single representative can be captured by villains,

Not really. If someone will be able to tamper the device and submit conflicting transactions then this will just split the network. This will be seen and just ruin the network. He can't print additional money in this way.

It has no incentives to do that. Device keys are second-factor keys. The user has its own, personal (software) keys. You need both to make a transaction.

The threat model is heavily based on tamper-resistance of the devices. But I don't think it can't survive. Also, tampering the device can ruin the network, but it can't print new money.

Yes, there should be a defense against device simulations. For example, a manufacturer can insert its root private key in the devices and use it for additional signing.

The hardware isn't supposed to connect to manufacturer servers, so how manufacturer is going to make decisions?

You can register another hardware key with your personal (software) key. It's mentioned in the article.

FIDO has a device attestation https://developers.yubico.com/U2F/Attestation_and_Metadata/ But their scheme indeed looks like flawed. There is a way to make it correct, though. Device manufacturer also has to injec

Silk Road is just one example, there a lot more. Though, you can use logic. Money transfers without governments control is what criminals want the most.

Avoiding 1,1,1, in a code like this for x1 in range(1, 10): for x2 in range(1, 10): if x2 in [x1]: continue for x3 in range(1, 10): if x3 in [x1, x2]:

Backtracking is not only a subject of logical programming. This definition [1] is quite general, so a loop with a single predicate can be called backtracking too. Though I agree that the word "backtracking" is mostly used in a log

From a more abstract point of view we just build a loop through all permutations of numbers 1,2,..,n. Probably the most efficient algorithm for this task is this one https://en.m.wikipedia.org/wiki/Steinhaus%E2%80%93Joh

The existence of a cloned physical key is not possible due to FIDO U2F protocol. Every sign operation increases a counter on the device. It's supposed that services will keep track of this counter and don't accept signatures with

I think it's time to put Bitcoin on the ignore list. You will never learn anything new about it, only the same stories: 1. It's a disastrous waste of energy resources. 2. HODLers like to compare it with gold and use it as a store

This is all valid points, except we can't predict how fast the number of qubits in a quantum computer will grow. Moore's law, even for classical computers, is just unscientific, in my opinion. Also, quantum mechanics is not only a
