How? It was already done with physical gold so we do know how that happened, but the other, can you explain it? If not, why do you make this claim?
If you're asking about bitcoin, I don't follow it that closely, but there have been instances of markets getting hacked or nuking people's accounts, but that's not exactly what I'm talking about.
There are two major problems with money, one is that loving it is the root of evil, and the other is the temptation to be dishonest with its creation, and there are many ways to do so, going back to the first bankers who issued more paper receipts than what gold they had in deposit because it seemed to them unlikely that the depositors would figure out the scam.
The major problem now is that money can be created outside of rules and without transparency so that the value of the existing money is decreased, which is a type of theft that occurs on the scale of many trillions of USD$ of value sucked out of the wallets of normal people every year.
Wall Street, for example, can effectively create money through both its reported and totally unreported exotic financial instruments, like those that led to the financial crash of 2008, e.g. collateral debt obligations (fractionalized mortgages from unqualified borrowers re-sold under false pretenses of high ratings). Because it is not required to report some categories of this type of money creation, partly enabled by the repeal of Glass-Steagall, the general rules of operation are broken for the benefit of a few and at the expense of the many. It's theft on an unimaginable scale.
The Federal Reserve system has immense power to create money, especially since the initial 2008 TARP where Congress increased the Fed's authority, so they gave TRILLIONS out in near-zero interest loans to the too-big-to-fail banks (I linked Ben Bernanke's 2009 admission of this earlier), and afterward just ran the printing presses for "quantitative easing" to provide liquidity for their endless Ponzi schemes, which they continue to do according to new rules they make up as they go.
Sometimes they break the letter of the law, sometimes the spirit, and this is inevitable without transparency mechanisms functioning constantly, which will never happen because the temptation to create money for oneself and the few who are in the position to do it in relative secrecy or the obscurity of complex check-kiting operations at Wall Street and the central banks is too great.
As far as bitcoin and blockchain technologies, how many instances of rug pulls do we need to see its vulnerability?
In addition to that, I believe that every technology that makes it into the public domain was created many years before its availability and is only allowed because it ultimately serves the purpose of those in control at the top. I am sure that whatever security blockchain tech appears to provide can be circumvented by another technology not in the public domain, either directly by a hack or indirectly by a legal control.
Therefore, I do not believe that blockchain money solves the inherent problems of the temptation of covert money creation, ie. the breaking of the rules made for the plebes to follow under threat of law, but always broken by the elites who worship mammon.
EDIT: After re-reading this and my earlier comment, I see that I'm being repetitive, but I hope I gave more detail that helps.
