February is Black History Month, and it’s worth recounting that cryptocurrency and blockchain technology have already had a significant impact on the African-American community.
Peoples of color own cryptocurrencies at consistently higher levels than white people, surveys show, while anecdotal evidence suggests crypto has also unleashed a wave of innovation and entrepreneurial energy in the Black community — from New York City’s new mayor converting his first paycheck into crypto to basketball star Kevin Durant launching a new special-purpose acquisition company to focus on cryptocurrencies and blockchain.
The African-American community has been actively engaged in the education challenge, according to Mesidor. “Over the last decade, it has been innovators of color in crypto that have launched education campaigns and built products and services to dismantle long-standing economic inequities in urban and rural areas here in America,” she continued. “The efforts of Black and Latinx industry leaders is the reason why crypto adoption in communities of color leads the nation by double digits.”

Any investment that is made to appear to look like it can save anyone is doomed to fail. MP clearly indicates such stories usually tend to be a warning of an intermediate to longer-term top. It will probably be one of the main reasons why BTC will most likely plunge to new lows before surging to new highs. MP states that the markets are not made for the masses and this story seems to imply that Blockchain via cyrtpo could help empower the black community.
Btw BTC is incredibly ineffective when it comes to the speed at which transactions occur. If it was adopted as a mainstream form of payment, it might hours to days for your fast food order payment to go through. So you would have to order your pizza several days in advance
Blockchains can be slow and cumbersome
Once again due to their complexity and their encrypted, distributed nature, blockchain transactions can take a while to process, certainly compared to “traditional” payment systems such as cash or debit cards. Bitcoin transactions can take several hours to finalise, which means there are inherent problems in the idea that you will be able to use them to pay for a cup of coffee in your lunch hour, unless the vendor is willing to take on an element of risk. And wasn’t that something which the “trustless” nature of blockchains was expected to remove from the equation?
In theory the principle extends to blockchain networks which are used for something other than as a store of value, for example logging transactions or interactions in and IoT environment. These chains – really just computer files, after all – have the potential to become slow and unwieldy as they grow in size, and the number of computers accessing and writing to the network grows. Hopefully this is a problem which will be solved with advances in engineering and processing speeds, but at this point in time it remains a problem, nonetheless.

And then we have Quantum computing which could end blockchain
Blockchain consists of encrypted nodes connected on a chain, which currently makes it almost impossible to hack. The order of entries adheres to the blockchain protocol, which makes it counterfeit-resistant.
To successfully hack a blockchain, you would need to alter both the targeted block and all of the blocks connected. Blockchains are synced throughout a peer-to-peer network. In this type of system, there is no central point of failure for hackers to penetrate. For a hacker to have a chance of penetrating the network, they would need to simultaneously alter at least 51% of the blockchain.
Altering half of a blockchain seems impossible now, but the power of quantum computers could easily crack the system.

In today’s technology landscape, the blockchain promises unbreakable data security, but that will all be undone as soon as quantum computers come on the scene. Blockchain security is based on mathematical puzzles that are incredibly difficult for even the best conventional computers to crack. One commonly used puzzle is to determine which two prime numbers have been multiplied together to create a new number, a challenge that gets nearly impossible as the numbers get bigger. In 1994, mathematician Peter Shor devised a way—called Shor’s algorithm—to quickly find a number’s prime factors and solve the puzzle. However, that algorithm requires a quantum computer to run
Possible solution is QKD but we all know nobody works on the solution until there is a big problem
Quantum Key Distribution (QKD) however takes advantage of the laws of quantum mechanics, allowing two parties exchanging secure data to detect whether a third party is attempting to eavesdrop on their exchange. Using quantum keys in conjunction with a blockchain network could be one way to help secure against attacks from both classical and quantum computers.
