Adiantum: Wide-block mode. This is not a primitive but rather a scheme of some sort (utilizes a combination of XChaCha20 + AES) <—- but where's the AEAD part that you get with the poly1305??
Ah, its in there per an explanation of the specifications.
States, "It works by first hashing almost the entire plaintext using a keyed hash based on Poly1305 and another very fast keyed hash function called NH"
NH? Never heard of that (hashed key function).
Feistel Network: Allows you to decrypt ciphertext that has been hashed right? Not sure need to check in on that

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
NEWS: Telegram supports Facetime video calls NOW!
Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
