TeleMessage, a cloned version of encrypted messaging app Signal, has suspended service following a security incident where sensitive materials were accessed by a hacker.

Rinke Zonneveld, CEO of Invest-NL, states that Invest-NL's investment safeguards the Netherlands' leading role in cryptography, particularly during this critical period of transition.

Secure Multi-Party Computation (SMPC) allows multiple parties to compute functions collaboratively while ensuring that individual inputs remain private, highly relevant in untrustworthy settings.

One of the main advantages of XOR is its reversibility. Applying XOR between the ciphertext and the key retrieves the original message.

In Go, hashing is categorized into two main types: non-cryptographic hashes like FNV for speed, and cryptographic hashes like SHA-256 for security.

The service, QuarkID, has been integrated into miBA, the city's seven-year-old app for accessing municipal services and documents. The idea, in short, is to give 3.6 million porteños - residents of Buenos Aires - greater control over their personal information. The ZK proofs will let users show that a document has indeed been authenticated by the government without disclosing information that is irrelevant to the task at hand.

"With the Spring 1.0 upgrade and the introduction of the Savanna consensus algorithm, we're achieving something rare in the blockchain world: changing our core consensus algorithm. Very few Layer 1 blockchains have ever done this. In doing so, we're standing on hallowed ground."
