This week, the keyword highlighted by Miden is 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐚𝐥 𝐏𝐫𝐢𝐯𝐚𝐜𝐲 (Practical Privacy)

This is not an abstract concept, but a real-world issue that all blockchain users will encounter and is often overlooked:

👉What kind of privacy do we actually need?

On most mainstream public blockchains, privacy is almost nonexistent.
For example, Ethereum, your wallet balance, every transaction, and the protocols you've interacted with are all open and transparent, anyone can query with a single click. It’s more like a permanently public bank statement, and it’s accessible to the entire world.

For ordinary users, this is already somewhat uncomfortable;
For institutions, enterprises, and DAOs, it’s almost unacceptable.

But going to the other extreme also presents obvious problems.
Chains like Monero with “absolute privacy” hide all transaction details, indeed protecting users, but also tipping the power balance too far in the other direction, making regulation almost impossible to intervene, which is why it is frequently “focused on” by regulatory agencies.

So the issue becomes very practical:
👉Complete transparency is not acceptable, complete concealment is also not acceptable, so what is the middle ground?

@0xMiden’s answer is: Practical Privacy.

It’s not about “hiding everything,” but about redesigning where privacy appears.

In Miden’s logic, data is executed locally by default, and truly sensitive transaction details do not need to be broadcast publicly. The chain only verifies, uploading proofs of “I did it correctly,” rather than the entire process of “how I did it.”

What does this mean?
You can prove that a transaction is compliant, valid, and rule-abiding,
without having to show all your assets, history, and business strategies to strangers.

To use a life analogy, it’s actually very easy to understand:
🔸Cash transactions: Completely private, but high risk and easy to abuse
🔸Bank transfers: Highly compliant, but almost no privacy
🔸Alipay/Privacy Payments: Sufficient privacy for ordinary people,
but still auditable and accountable for the system

What Miden aims to do is precisely the third.
It’s not privacy for “hiding dirt,” but providing protection for normal people, normal business, and normal financial activities.

This is why I believe the concept of “Practical Privacy” is truly important.
Privacy should not be demonized, nor should it be absolute. The meaning of privacy has never been about making bad people disappear, but about ensuring good people don’t have to run naked.

As blockchain moves toward large-scale adoption, and more ordinary users and institutions enter the on-chain world, privacy is no longer an “optional feature,” but part of the infrastructure.

And what @0xMiden is trying to do is find the most comfortable and also the most realistic middle ground for the future of finance.
