Will a cryptocurrency be created using a quantum random number generator by 2036?

According to physicsworld,

When numbers are used to securely encode information, the randomness of those numbers is crucial: a string of truly random numbers is one that a hacker can never guess. In classical physics, however, all processes – even chaotic ones – are deterministic, making true randomness impossible. [..] In the quantum world, in contrast, “there are these fundamentally non-deterministic processes,” says Nathan Walk, a physicist at Freie Universitat Berlin, Germany

Proof of Stake (PoS) is a type of consensus algorithm used by cryptocurrencies. Unlike Proof of Work (used by Bitcoin), PoS does not incentivize extreme amounts of energy consumption. PoS uses a pseudo-random process to select the validator to create the next block.

Scott Aaronson, a theoretical computer scientist with a focus on quantum computing, wrote in his blog that

because of my certified randomness protocol, which shows how a sampling-based quantum supremacy experiment could almost immediately be repurposed to generate bits that can be proven to be random to a skeptical third party (under computational assumptions). This, in turn, has possible applications to proof-of-stake cryptocurrencies and other cryptographic protocols.

Random number generators have been shown to be vulnerable in the past and the future of PoS cryptocurrencies may rely on their security. During the Hot Lotto fraud scandal,

It came to light in 2017, after Eddie Raymond Tipton, the former information security director of the Multi-State Lottery Association (MUSL), confessed to rigging a random number generator that he and two others used in multiple cases of fraud against state lotteries. Tipton was first convicted in October 2015 of rigging a $14.3 million drawing of MUSL's lottery game Hot Lotto.

Additionally, as part of the Bullrun program, the NSA was reported to have a backdoor in the Dual_EC_DRBG random number generator.
