1. According to present evaluations, ECDSA is possible to break with 1000 qubits, true or false?

2. Balancing the proof-of-work scheme needs approximately equal opportunity to obtain calculation power, which enables quantum computing to unbalance the present proof-of-work schemes, true or false?

3. When designing a blockchain, there are four factors to consider: speed, transparency, privacy and security. These factors are interconnected so that there are two pairings possible. If we value transparency which of the following is lost with a transparent system?
