covering a lot of #cryptography and #privacy stuff lately. Time to revisit some of my older privacy-related threads

find below

- the #privacy bull case

- @SecretNetwork and its TEE infrastructure

- @MantaNetwork and zk-tech

- @DuskFoundation and zk-enabled #RegFi

1/ the privacy bull case

$SCRT $MANTA $PHA $DUSK $XHV $MINA

2/ TEE infrastructure on $SCRT network

5/ the rise of the zkEVM

zk-rollups enable scalability & privacy. While for now most teams focus on scalability, the privacy preserving capabilities of ZKPs will surely gain importance over the coming months. Hence also worth mentioning here

0/ What are Non-Interactive Zero-Knowledge Proofs (NIZKPs)? 🧙‍♂️✨

(0/10) 🧵👇
1/ First of all, what are zero knowledge proofs (ZKPs) in general?

ZKPs are a #cryptographic technique that allow individuals or entities to prove to another that a statement is true, without revealing any information beyond the validity of the statement.
2/ One variant of ZKPs are non-interactive zero-knowledge proofs (NIZKPs), which don't require interaction between the certifier and verifier.

0/ What is Homomorphic Encryption (HE)? 🧙‍♂️✨

(0/10) 🧵👇
1/ HE is a cryptographic tool that allows you to perform certain types of computations directly on the homomorphically encrypted ciphertext, generating the same results as if you performed the operations on the plaintext.
2/ There are two types of HE: partially homomorphic encryption (PHE) & fully homomorphic encryption (FHE). PHE allows for a limited number of operations on the ciphertext (e.g. addition or multiplication), while FHE allows for any computation to be performed on the ciphertext.

0/ What are Ring Signatures? 🧙‍♂️✨

(0/16) 🧵👇
1/ Ring signatures are a privacy technology that aims to keep user's identities private when making (signing) transactions in public #blockchain networks
2/ In ring signature schemes, a group of users, called the "ring," can sign a message anonymously using their personal secret keys.

0/ What are Hash Pointers? 🧙‍♂️✨

(0/7) 🧵👇
1/ Hash pointers are a type of pointer that point to a specific location in a data structure, specifically a block in a blockchain. They are an essential part of the structure and security of blockchains.
2/ To understand hash pointers, it's helpful to know what pointers are more generally. Pointers are variables that store the address of another variable, allowing you to indirectly access and manipulate the value of a variable by referring to its memory location.

0/ What are Hash Functions? 🧙‍♂️✨

(0/12) 🧵👇
1/ A hash function is a function that converts data into a fixed-size output, also known as a hash.
2/ Cryptographic hash functions are a type of hash function that are designed to be one-way functions, meaning it is computationally infeasible to find the original input from the hash output.

0/ What is the Elliptic Curve Digital Signature Algorithm (ECDSA)? 🧙‍♂️✨

(0/21) 🧵👇
1/ The Elliptic Curve Digital Signature Algorithm (ECDSA) is a digital signature scheme that is based on the algebraic structure of elliptic curves. It is widely used in many #cryptographic systems, including $ETH, $BTC, and other blockchains.
2/ In the #Ethereum blockchain, ECDSA is used to sign transactions and messages to prove the authenticity of the sender.
