Was looking for something else related to Ethereum, but saw this Reddit comment & felt compelled to respond.
1. Ethereum's version of keccak is different than the SHA3 standard because they decided to move ahead before the authors of the algorithm sent in their final submissions (to the NIST competition; 'Blake' was another finalist here).
2. The "NSA" did not force the authors to tweak their algorithm. The U.S. agency responsible for holding the competition, liaising w teams, publishing information & ultimately adjudicating the competition was the NIST.

Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised.

How to Use Bitcoin?
n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
