After watching the latest Veritasium video about how Newton figured out a novel approach to solving PI which was dramatically simpler than the previous thousand-year old methods, I wonder if someone will come along and figure out a simple mathematical way to break these encryptions. That would be horrifying of course, but also really cool.
More cryptographic details: Bitcoin uses the SHA-256 and RIPEMD-160 hash functions for public keys. It uses double-SHA-256 for transaction IDs and blocks (mining).
Related question, what are the dominant NFT platforms. I only know of ETH based tokens, but I assume there are others... which is a bit weird for something that's supposed to be unique. Could you be unique on two different platforms and sell a token "twice"?
Perhaps this only refers to the cryptography used to sign transactions, i.e., cryptography used by the clients or wallets. For instance, Algorand uses additional cryptography such as verifiable random functions. Nevertheless, extremely valuable.
This is a great table of information. It’s news to me that Tether is based on Ethereum tokens. If Ethereum falls out of favor and offers an appealing 51% attack, or if the proof of stake transition has a vulnerability, would this affect Tether spectacularly and then impact BTC and all other CCs?
