Miden Blockchain

Years in the making.
Based on research at Meta and Polygon, Miden redefines financial infrastructure.

One-of-a-kind

In development for seven years, Miden's combination of privacy, security, and scalability is unmatched.

01

Programmable privacy

On Miden, users decide who can see their transactions.

02

Client-side proving

By moving execution off-chain, Miden's infrastructure becomes highly scalable.

03

Quantum security

Our ZK-STARK infrastructure is future-proofed against quantum computing.

Client side execution

Every blockchain broadcasts everything.  Miden doesn't.

Bringing practical privacy to financial markets. Selective disclosure, regulatory compliance, and counterparty confidentiality — engineered for the institutions that move global capital.

Miden vs Other Chains

How Miden stacks up

The key differences between Miden and other blockchains

Old blockchains
Every balance and transaction is public by default
Anyone with a block explorer can see your net worth, your history, and everything you hold
All "state" lives on-chain forever, so the ledger bloats as usage grows
General purpose, not designed for any specific use case
Miden
Selectively private: you choose what stays private and what goes public
Only a ZK proof gets posted to the chain, so disclosure happens on your terms
State lives with users, not the chain. The network stores commitments and stays lean at any scale
Purpose-built for private, compliant finance, not an all-purpose chain retrofitted for it
Live with Miden
