Vitalik Buterin has introduced Kohaku, a native privacy framework designed to make everyday transactions more private without breaking the rules that regulators and institutions rely on.
It is the most ambitious privacy upgrade the network has outlined so far. Kohaku aims to bring simple, intuitive privacy to Ethereum at a moment when interest in secure crypto activity is growing across the market.
How Kohaku Keeps a Transaction Private
The easiest way to understand Kohaku is to follow a simple flow. Imagine Alice wants to send 1000 dollars in crypto to Bob. Bob has a normal public wallet that anyone can see. To gain privacy, he creates a special stealth keypair that is linked to his real wallet but not visible to the public. When Alice wants to pay him, she uses Bob’s stealth key to create a one-time stealth address. This address exists only for that single payment.
vitalik introduced Kohaku—ethereum’s native and compliant privacy framework.
it’s the biggest privacy upgrade path ethereum has ever outlined.
i try to explain the flow in the most intuitive way possible.
so let’s say alice wants to send $1k to bob.

Alice sends the funds to the stealth address. Bob scans the network with his stealth key to see which of these one-time addresses belong to him. Once the transfer is completed, the stealth address becomes inactive. No one watching the blockchain can easily connect that address to Bob’s main wallet. Kohaku is doing all of this behind the scenes. It takes Bob’s public information and generates an ephemeral address that breaks the link between the sender, the receiver, and the long-term identity that follows a wallet around.

Ethereum’s main flaw is transparency. Every wallet action is public and relies on centralized RPCs.

This solves a real problem. Right now, anyone can track payments and map wallet activity with simple tools. A privacy solution that works at the protocol level gives regular users the same privacy that large financial networks already use.
Why Kohaku Stays Fully Compliant
Privacy does not mean secrecy. Kohaku takes a balanced approach that gives users privacy by default while allowing them to disclose information when required. The key idea is selective transparency. If a regulator, auditor, or institution needs proof that a payment belongs to a verified user, that user can reveal the link between their main wallet and their stealth address. Until they choose to do that, the blockchain keeps the information private. This gives individuals and businesses confidence without exposing every detail publicly.

A good example of why this matters comes from the growth of tokenized assets. BlackRock’s BUIDL fund passed 500 million dollars in assets within months of launch, showing how fast regulated institutions are moving on chain. These groups need privacy for normal operations, but also need clear audit paths. Kohaku is built for that world.
A New Direction for Ethereum
Kohaku marks a turning point for Ethereum. It blends privacy with openness in a way that fits modern regulation and the growing use of blockchain in traditional finance. Developers, investors, and newcomers now have a clearer path toward private activity that still works within legal and institutional frameworks.
