Programmable Tokens on Cardano: How a Token Learns to Follow Rules

Most blockchain tokens can go anywhere, to anyone, with no questions asked. That freedom is powerful, but it is also the reason banks, fund managers and stablecoin issuers have struggled to put regulated assets on a public chain. Cardano's new programmable token standard, CIP-0113, gives a token its own rulebook that the network checks every time it moves, while the token stays a normal Cardano asset. Here is how it works, in plain words.

A Proof Is Not a Promise: Closing the Hole in Our Midnight Age Check

We built a Midnight circuit that proves someone is over 18 without revealing their birthday. It compiles and produces a valid zero-knowledge proof, yet a 16-year-old could still pass it. Why? Because a proof can verify the math without verifying the truth of its inputs. This article explains the flaw in plain language and explores how trusted time and authenticated birth-date credentials can help fix it.

DUST Sponsorship: How Midnight Lets New Users Transact Without Holding a Single Token

A brand-new Midnight wallet holds zero NIGHT, which means it generates zero DUST and without DUST, it can't submit even its first transaction. DUST sponsorship is the mechanism Midnight built to break that deadlock: one wallet covers another's fee, without ever being able to act as that user or alter what they're doing. Here's exactly how it works, sourced directly from Midnight's official guide.

How Midnight Keeps a Secret on a Public Blockchain: Hash Functions and Cryptographic Commitments Explained

A blockchain is supposed to be an open book that anyone can read. So how does Midnight let you prove you're over 18, prove you own something, or prove you paid a bill, without ever putting your birthdate, your identity, or your balance on that open book? The answer is two simple ideas doing almost all of the work: hash functions and cryptographic commitments. Once you understand them, the rest of how Midnight protects your privacy stops feeling like magic.
